1.1 Purpose of the NATSPEC National BIM Guide: The National BIM Guide is a reference document to be read in conjunction with the BIM Project Brief which defines the specific requirements for each project. A BIM Brief project, whether developed using NATSPEC's BIM Brief or otherwise, is expected to be formulated by the client in consultation with the project team. The guide can also be used by consultants as a planning tool to explain the proposed services they provide while preparing bids for projects. The National BIM Guide is designed to help clients, consultants and other stakeholders to explain their BIM requirements into a nationally consistent A. This will reduce confusion and duplication of effort. The National BIM Guide is an adaptation of the VA BIM Guide and the development philosophy is to keep as much of the original document as possible. Common sense is expected to interpret Americanism accordingly.

1.2 Design Requirements: It was essential to clearly define and understand the constraints associated with the design as preconditions for a successful design. The same principles apply to formulating requirements for using BIM: • Take the time to understand what is needed. • Realistic assessment of abilities and capabilities. • Defining the scope of the service. • Managing expectations and risk. • Award allocation proportional to effort and responsibility. For this reason, there is information in this document on the disclaimer of legal liability - it is the users' professional judgment that is responsible for submitting a request to determine what is appropriate in a given situation. It is highly recommended that a structured process define the requirements for using BIM in the project, customer and project team involvement is initiated as early as possible. References to documents that can help this (eg Penn State University's "Integrated Computer Design Research Program" Penn State University's BIM Project Planning Guide) can be found at the end of the NATSPEC BIM Reference Schedule.

1.3 National BIM Guide Documents NATSPEC: The National BIM Guide works with a series of supporting documents that should be compiled in a coordinated manner and read in conjunction with each other. All of them can be downloaded for free from www.natspec.com.au. Click on the "NATSPEC BIM" logo. They are: • The NATSPEC National BIM Guide (this document) is a reference document that outlines roles and responsibilities, collaboration procedures, approved software, modeling requirements, digital products, and documentation standards. Documents the range of possible applications of BIM in projects. • The project's BIM Brief documents the detailed requirements of the project. You can expand it using the NATSPEC Short BIM Template. In addition to identifying the project and project team members, it provides places to identify what BIM is to be used for in the project. It is also used to record standards from the NATSPEC BIM Reference Schedule. This layout allows the necessary flexibility to select the references to match the design details. The NATSPEC BIM Reference Program is a list of documents and standards to be considered as references that can be cited in a national BIM guide. The specific documents selected to be used in: The project is recorded in a BIM Brief. • NATSPEC BIM Object / Element Matrix is ​​a series of Microsoft Excel spreadsheets (.xls) that define a large number of objects and elements and their properties according to Uniformat / OmniClass classification and Development level (LOD) at different stages of the building life cycle. The purpose of this structure is to enable each edition of the National BIM Guide to function as a primary reference to document and limit the entire edition to a BIM Project Summary. This allows the National BIM Guide to be tailored to individual projects, while allowing for gradual updating in response to user needs from release to editing within a consistent, recognizable framework.

1.4 How to use the National BIM Guide NATSPEC: The National BIM Guide is not intended as a one-size-fits-all document that governs the use of BIM on all projects. It is impossible. A separate BIM project description is used to define project-specific requirements. Once the requirements for using BIM in the project have been determined and prior to the formal project, the National BIM Guide clauses begin, which must be retained, changed or deleted in order to meet the requirements documented in the BIM Brief. The BIM Brief contains the provisions of the National BIM Guide and should be read with it and the Project Agreement. A key element of the national BIM guide is the requirement for a BIM management plan (BMP) (sometimes also referred to as a BIM performance plan). The BMP is used to describe in more detail how a project will be executed, monitored and controlled in relation to BIM in order to meet the requirements written in the BIM Project Brief. NATSPEC BIM Object / Matrix Element can be used as an aid in BMP development. Other uses for the BIM object / element matrix include: • As a tool for the design team to decide what information should be included in the model at different stages of the project, and by whom. It can only be used for planning and guidance or for documenting an agreed agreement of obligations and responsibilities. • As it contains parameters specific to the Construction Information Exchange (COBie) for construction operations, it can be used during the design, construction and commissioning phases of a project to record information to be communicated for facility management purposes. • You can use it as a reference to ensure that all model object parameters follow a consistent naming convention and reflect industry standards. Whether and how the Object / Element BIM Matrix is ​​to be used in the project should be recorded in the Shortened BIM version of the project.

1.5 Exemptions: There may be occasions where compliance with parts of this standard may be problematic. In these cases, each negotiated waiver will be recorded in the contract.

2.1 Purchasing Strategy: The procurement strategy of the project will determine the creation of the BIM model, so a decision is necessary to use Design-Bid-Build (DBB) (traditional method), Design and Construct (D&C), Integrated Project Delivery (IPD) or one of the many other procurement methods are defined early in the project so that: BIM can be properly structured and managed to support procurement strategies. Contracts will specify the integration or separation of risks and responsibilities of the design and construction contracting entities and therefore the level of development (LOD) and segregation of duties. For example, there may be only one BIM Manager in the entire project if an IPD or D&C is used, and potentially two, a Design and Construction BIM Manager if a DBB is used. Likewise, the contractual risk will also determine whether they exist separately for the design and construction intent of BIM models, or whether they can be combined into a single model. Where BIM models are to be used for design / documentation and construction, a BIM management plan (BMP) should address how the model (s) can migrate between stages with minimal effort. Customers often require data interoperability as a strategic management issue in order to provide access to data building information throughout the asset's useful life. Therefore, any software that meets the customer's interoperability standards is acceptable for use in their projects, subject to approval. It is also very important available national standards, classification systems and protocols such as OmniClass, Uniformat and NATSPEC are used to develop models so that information can be machine readable and customer-standardized management goals. Maintain the unique global unique identifiers (GUIDs) assigned in the BIM data tools in workflows.

2.2 BIM Responsibilities: BIM Creation Tools, Data Integration and Teamwork Environment will be used to develop and present project information and documentation as required by the customer submission manual. The use of BIM should be maximized for design reviews, decision support, design analysis and quality assurance of the design phase. Presentation models, flights, etc may be required to present a design solution effectively or more specifically for the client or other stakeholders. It is the responsibility of all consultants and contractors to have or procure, at their expense, the trained personnel, hardware and software needed to successfully use BIM on the project. The equipment used by subcontractors during on-site coordination must meet the requirements of the software being deployed as well as not causing delays in modeling and redrawing. All technical disciplines (design) will be responsible for the integration and reliability of their data and contributing to the preparation of coordinated BIM.

2.3 Data Re-use: The ability to possess, re-use and properly manage construction data over the entire lifecycle of a facility is gaining importance for the customer. Therefore, the accurate creation, management and management of building information when creating a project are of utmost importance. Data created during planning and refined during the project implementation process can be a valuable resource for Facility Management (FM). The final BIM elements require the submission of BIM models for this purpose after construction.

2.4 Conditions of Use: The terms Design Team, Engineering Team, and Design / Build Team are used in this Guide to help determine to which group the guidelines apply. However, as purchasing strategies may define risk differently, in some projects responsibility may be transferred to the consulting team or the procuring entity, or both. The contract should properly define the obligations of the parties before BIM modeling begins.

2.5 Open standards: To ensure the use of the building information lifecycle, information supporting common industry outcomes should be provided in existing open standards, if available. For those contract products whose open standard formats have not yet been finalized, the results should be delivered in a mutually agreed format that allows building information to be reused outside the context of proprietary BIM software. The formats used are the best specified in the BIM management plan and include at least the following standards: a. The current version of the MFC (Model Foundation Foundation) (IFC) Model View Definition (MVD) formats: • Coordination: this format will be required for all products needed to demonstrate coordination of design discipline prior to construction or coordination of construction industries supporting the efficiency of fabrication, staging and assembly of prefabricated building elements. In addition to the file (s) coordination view, if required, the designer and contractor will provide a highlight report of automatically detected (hard and soft) clashes and identification of clashes that require further work by design or construction team. • Facility management: parts of this life cycle oriented data format may be required for a variety of different building information items to replace paper items. Products for FM MVD submission in COBie format include, but are not limited to: o Verification of the design solution against a design program (PFD). o Scheduled lists of buildings and equipment. o Construction Submission Register Requirements. o Identification of installed equipment and all labeled construction products. o Products to be handed over to the facility. b. Portable document format: copies of all validated documents and other documents normally shipped in traditional paper formats will be provided in PDF format. Documents developed directly by the project team will be converted to PDF format to allow text selection in the document. Documents by other authors but used by the project team (such as manufacturer data sheets) will be provided as PDF files provided by the manufacturer. Documents will be available if they are not available as PDF files from their authors scanned to create image-based PDF documents. down. ASTM E57 3D file format (for 3D laser point cloud data): Copies of approved documents to be presented as - embedded services and building conditions will be provided in the 3D ASTM E57 file format (per ASTM E2807), unless otherwise agreed with the project BIM manager.

BIM MANAGEMENT PLAN (BMP)

3.1 Introduction:

Description: A BIM Management Plan (BMP) is a formal document that sets out how a project will be made, monitored and controlled in relation to BIM. It is required to develop a BMP to provide the information / master data management plan and assign roles and responsibilities for modeling and data integration in the initiation project.

Requirements: BMP will align the needs and requirements of the procurement strategy in the project with PFD, technical customer standards, skills of team members, construction industry capabilities and technology maturity. Through this process, team members and project management jointly determine how, when, why, at what level and for which project results will be applied BIM In those projects where construction information is available at the design stage (using D&C or IPD project procurement strategies), the BMP will cover both design and construction activities. Where a DBB (traditional) procurement strategy is applied, a separate BMP for the project and potentially for construction developed and shipped to the customer with a focus on the model and data transfer from the design team to the construction team. The BMP should be considered a living document and it will be continuously developed and refined throughout the project lifecycle as required to ensure that the project is on schedule and meeting the requirements. Include a proposed method to facilitate this (eg Scheduled Review Meetings) in the initial BMP.

3.2 Designing the BMP: The BIM manager of the design team will submit the BMP to the client for review and approval prior to commencing the schematic design. Other than the BIM uses excluded by the BIM Brief project, Project BMP at least addresses:

The design team will be responsible for providing: • Federated BIM fully coordinated and assembled in model validation software format, eg Navisworks, Solibri. • Separate copies of each technical discipline model in the original software development tool • 2D plan set, derived from an assembled BIM, for contract bidding.

5.2 Auction of the structure: a. The qualifications, experience, and previous success in coordinating BIM and producing the proposed Construction BIM Manager, Contractor and major subcontractors to achieve the client's BIM goals should be part of the evaluation criteria when selecting a contractor. b. During the bidding, the application of the BIM Standards will be announced and checked with potential bidders and then verified with the selected Contractor and major subcontractors prior to construction commencement. down. The Contractor will have access to the Project's BIM during bidding and construction. Bid solicitation determines the legal status of the model to bidders (binding, informative, reference, reused) by specifying the contract record document (BIM models (models) or a separate set of 2D plans). This decision will be made based on the client's business interests, market maturity for BIM use, and other factors. re. Regardless of whether the project's BIM model (s) is a contract record, once the contract is awarded to the construction, the following must be provided to the appropriate contractors when required: Navisworks, Solibri. • BIM model (s) with coordinated design and all native BIM files.

The subcontractor's production models should be coordinated with the design model. Any corrections to the model design that need to be done prior to fabrication and construction must be reported to the design team in the Request for Information (RFI) form. Collision reports may also be issued by the Contractor as background information on RFI and uploaded documents.

6.1 Introduction: The success of a BIM-enabled project delivery process depends very much on the level at which the overall Design / Construction team can produce and manage information together for the duration of the project. This section describes some of the management procedures you can use for this purpose.

6.2 Collaboration Standards: In the absence of the documented Information Management Standards required by the client, the BIM team will set a Collaborative Information Management Standard to be applied to the project. Any changes deemed necessary to these standards must be documented. Following BIM approval of the Collaborative and Change Information Management Standard, the Team will be adopted and managed to be consistently applied by the BIM Manager. The collaboration information management standard covers at least the following: • Lines of responsibility. • Communication modes. • Reporting procedures. • Approval and signature procedures. • Information management and exchange protocols. • Model sharing protocols. • Model coordination procedures. • Procedures for creating models and drawings.

6.3 Standards Management: National BIM Guide, Collaborative Informative Management Standards, BIM Modeling Standards, and CAD / Drawing Standards can sometimes cover similar subject areas. (See Modeling Requirements and 2D Drawing Requirements.) While areas of overlap or conflict should be identified in the project BIM glance, it is possible for inconsistencies to emerge between documents during the design. In these cases, BIM Manager will be notified immediately. In response, the BIM manager will determine, in consultation with the BIM Team (if necessary) which document will take precedence or if changes are required, and advise the entire BIM team on the ruling.

6.4 Project initiation orientation BIM Standards: Once the project is awarded, the client should facilitate a pre-negotiation orientation meeting which will review all client requirements including BIM requirements and answer questions from the project team.

6.5 Facilitating BIM Coordination: Face-to-face meetings where BIM models are used for design review and BIM clash detection / coordination Coordination is the preferred means of facilitating technical discipline coordination. However, a different design of circumstances will determine the most appropriate approach. Remote coordination measures such as web conferencing should only be considered after team members have established working contacts through face-to-face meetings or where no other practical alternatives exist. Consider the following ways to facilitate BIM coordination, and write down those selected in BIM Project Brief: BIM coordination meetings in an appropriately equipped room at a location agreed by the BIM team. b. BIM coordination meetings in the BIM coordination room. Depending on the project procurement strategy, there may be one room or there may be two rooms in succession. During construction, BIM Coordination The room should be located on or near the construction site to coordinate production models with relevant professions. For each BIM coordination room appropriate equipment and tools should be provided to meet the required performance requirements. down. BIM coordination meetings with the use of web conferences (webinar). The party responsible for infrastructure provision is identified when developing the BIM Management Plan (BMP)

Consider the following BIM applications and write down the ones selected in the Short BIM Project. Everyone should be systematically assessed against the goals of the project and the value they add. Where required by the BIM Brief project, below describes how to use BIM for each recorded task:

7.1 Design definition, planning and preliminary design

7.1.1 Modeling of Existing Conditions: Define a range of existing conditions to be modeled based on the project details in the Project BIM Brief, e.g. within property boundaries, facility plus directly adjacent buildings and objects, defined precincts Also define the required level of model detail, e.g. only block forms, detailed modeling, photorealistic modeling. Turn on a datum defined relative to true north and AHD. Customize your site with GIS information, North, East, etc. Select one of the following options: a. Create a topo 3D surface based on survey information. b. Model existing subsurface services and functions based on available information. down. Model geotechnical conditions. re. Integrate laser scanned data on existing buildings, services, vegetation and functions. to me. Split large sites into sites for individual buildings, development stages, etc. as per project requirements requirements

7.1.2 Site analysis: a. Failure of model planning, envelope building, etc. b. Map terrain gradients and drainage patterns. down. Access to maps and circulation patterns. re. Model view corridors, privacy patterns (to and from the site). to me. Model solar access and shade patterns. fa. Model climatic influences, wind patterns, etc.

7.1.3 Validation of space and equipment: General: Customers are encouraged to use Architectural Programming Software (APS) such as Affinity, Codebook, dRofus to compile their space (rooms etc) and hardware requirements. They are useful aids for brief formulation and creation of a design program (PFD). For applications to be truly effective, they must be able to export and import data to and from the model. APS also provides the BIM team with the ability to manage, track, and report space and model equipment during design and construction. This data can also be reused for facility management purposes. The purpose (s) for which the floor area will be measured (program validation, leasing, surface to floor ratio, etc.) should be defined before modeling begins as this will determine the appropriate measurement method (s). See appendix A: Measurement of space. Requirements Space and equipment data are captured in the BIM model. All BIM models must retain the tag field name and text values ​​found in the customer program. To do this, the final PFD for the project must be electronically exported from the SPA for import and reuse in BIM. The export can then be imported into BIM "space" software tools and hardware data into "items" or "objects" suitable for a specific BIM software or data can be linked to a database external to the BIM software. Premises and equipment should be obtained from the model and electronically verified against the PFD at each transfer stage.

7.2 Architectural modeling (design)

7.2.1 Architecture - spatial and material design models: The moment of level of development (LOD) required for components or systems will be entirely dependent on the procurement strategy used in the project as the results and their timing will be different for DBB than for D&C or IPD. The BIM Object / Matrix element shows the evolution of an architectural spatial model as it is being refined the design process as the design progresses towards construction. After selecting materials and components, general assemblies must be assigned material properties, sizes, tracked sustainability credits, and other specific component information defined to clearly identify building elements such as walls, floors, roofs, doors, and windows. Program space requirements are modeled in a spatial model and validated electronically against the PFD at each stage of the project and submitted with the required results.

7.2.2 Project visualization for communication and functional analysis: General BIM provides the possibility to build a virtual building and virtually test this building for the functionality of the project. This allows project stakeholders to see and understand design solutions that represent reality and can work on improving the building design before construction begins. The project team is encouraged to do so to find BIM performance and applications to improve project communication. The model should be at least integrated with design reviews, submitted reviews, and views of the 3D construction documentation. The areas that would do so will use 3D imagery and flyovers during the design and construction process identified and recorded in the BMP (s). Visualization tools relate to animated models, cruising flights, static 3D renderings, 4D process sequencing, and other techniques to aid decision making and understanding. Note that even if they contain BIM, most of the source information needed for a visualization may need to be further refined in a specific animation and visualization software to achieve the intended results. Particular attention should be paid to passenger and maintenance considerations during design. Consider the following uses BIM for communication purposes and records selected in the BIM Project Brief. Purpose, intended users, nature (static or animated), level of detail (outline, photorealism, etc.) and the scope of each should also be defined: Imagining behind. Views from the outside of the building. b. Enhanced visualizations for presentation using photorealistic rendering software and photomontages of the proposed design in the context of an existing street or landscape. down. Blackout studies of neighboring properties at times determined by the planning authority. re. Views of the interior of the building. to me. Simulated films from the building, eg Walks, "flights", "passages", "flights". Functional analysis for. The distances between the main functional spaces. b. Sighting lines for surveillance and security purposes. down. Processing areas where time and volume can be problematic, such as areas used for queuing, waiting, and delivery. re. Supply, processing and distribution (SPD) of materials. to me. Main construction equipment reservations for use, repair, maintenance and replacement of graphics or animations. fa. Color coding of floor panels to identify types of space functions, location of departments, circulation zones and floor surfaces.

7.2.3 Code Checking: Use specially designed model check software, eg Solibri configured to check code. Define the code and clauses against which the model is to be validated, including applicable standards.

7.2.4 Assessment of sustainable development: a. Define an evaluation schema used to evaluate the model, such as Green Star Office. b. Assign properties to feature models based on schema schema criteria, eg Room air quality or link them to an external database for management. down. Adapt your measurement and material quantity planning methods to your assessment methods.

7.3 Modeling and structural analysis: a. Other disciplines should provide the structural engineer with models that determine the location and range of all major building components, including required transitions and finishes. b. Identify the load-bearing and non-load-bearing elements. down. Identify loads by all major installations and devices.

7.4 MEP modeling and analysis

7.4.1 Energy Analysis: The energy simulation and life cycle cost calculations are based on information obtained directly from BIM and validated by energy modeling. Models are created according to the LOD and the quality required to perform an energy analysis appropriate to the phase and decision requirements of the project. When there are internal spaces defined, they will be modeled using internal environment parameters for early MEP design. Design teams will use energy modeling and sustainable design software that extracts the BIM data into the appropriate file format for the analysis tool. Consider the following BIM applications for energy cost and life cycle analysis and write down those selected in Project BIM Brief: Passive Design Analysis - Model the building to enable use of specialized applications such as Computational Fluid Dynamics (CFD) Software. b. Mechanical Systems Analysis - see Virtual Testing and Balancing. down. Life Cycle Analysis (LCA) - Use certified analytical applications such as LCADesign. Use the material quantity of the measurement method and assign material codes to model objects according to the application requirements. Obtain LCA Data on products and materials from agreed sources using international standards assessment. Apply protocols to correctly use the data published by the source organization.

7.4.2 Virtual Testing and Balancing: Virtual testing and balancing of the architectural model will be used to support sustainable building systems design and analysis. You can read room data from a linked architectural model to create mechanical spaces (each space is the same as a room in the architectural model). Multiple spaces have been combined to create zones. This data can be used to calculate native heating and cooling analysis that is built into MEP software or exported with file formats such as gbXML to an external analytical application such as Trane / Trace or the US Department of Energy Based Analysis Programs (DOE ). Architectural Engineering (AE) consultants can then restore this data in the model to check their performance. One method is to create a Space / Room schedule that will display the calculated airflow versus the actual airflow. See Figure 7.4.2 below. All air flows can be checked for load balancing to the terminal box and the entire return path to the AHUs. Check with MEP modeling software companies for more information.

Define the scope of application, e.g. I. Only start and quantitative valuation. II. 5D BIM - Cost data related to 4D BIM, ie a model linked to time or schedule data. Use for generating cash flow reports etc.

7.6 Structural models

7.6.1 Clash Detection / Coordination: General • It is the responsibility of the design / construction team to conduct and manage an appropriate and thorough confrontation Detection process to ensure that all major interferences between building elements are detected and resolved prior to construction. The aim of the design / construction teams should be to reduce the number of shifts during construction due to major disturbance to the building to zero. • The BIM manager should assemble a model composed of all parts of the model for each design discipline with the goal of performing visual inspection of the building design for spatial and system coordination. Vertical shafts should also be inspected to ensure that there is adequate space for all risers. Mechanical systems (including service and maintenance access space) and that all shafts are in line with floor to floor. Before each scheduled co-ordination meeting, an updated clash report will be issued. BIM Manager to Technical Consultants. • The approach to coordination / clash detection will depend on the project. In the case of a multi-story project, for example, models may require a level breakdown for mechanical plumbing services coordination (MEPF). If the floor is particularly large, you may need to divide it into zones to reduce the file size. Typically, 3D collision detection / coordination continues on one floor until the building systems are fully coordinated and then continues on the next floor up. • Coordination software should be used to compile various design models for electronic identification, jointly coordinate resolutions, and track and publish disruption reports across all disciplines. The technical disciplines are responsible for updating their models to reflect the coordinated resolution. • The team will regularly review the model and clash reports during coordination meetings as needed (usually weekly) at all stages of the design, until all spatial and system coordination issues have been resolved. • During the construction phase, the accuracy of the production models should be verified. Prior to each production for submission for approval, manufacturing contractors will submit their models to the Contractor's BIM Manager for integration and conflict detection / coordination and resolution. • Internal Conflict Resolution: Project consultants and subcontractors who are responsible for multiple scopes are expected to coordinate clashes between these scopes before these BIM Manager models are available for spatial and system coordination. • Spatial Coordination Verification: Verify and track resolved conflicts of all trade co-ordination issues that may result in site changes or conflicts should be provided to the client at key points in the project, and should be fully resolved prior to bidding. • To facilitate identification during the 3D collision detection / coordination process, elements must be represented by the colors represented in the collision detection color coding standard. Minimum requirements for spatial coordination and collision detection behind. Architecture + Construction: Sub-class spaces, proposed floor slabs with large aisles, floor-to-floor heights, beam clearances, heavy media locations, floor loads, core and vertical shafts, beam depths and required clearances, floor-mounted equipment, slab thickness, columns , column plugs and seismic bracings. Provide adequate space for construction and maintenance access to structural components, construction equipment, and distribution systems. b.

Possible future extensions will be considered in consultation with the customer and will be trouble-free. down. Architecture, structure and telecommunications MEPF / HVAC +: main distribution and collection systems, configurations and sizes of pipelines, ducts, cable ducts, power cables, fans; diffusers; inlets, large compressors Reservations regarding equipment maintenance, filter removal and equipment removal and replacement should be modeled with the equipment and signed for adequacy of the space reservation should be obtained from the facility manager if appointed. re. Architecture + Safety of Life Fire Protection: Safe zone and location of fire pipes, exit paths and requirements for exit distance, fittings and pipe penetrations. to me. Major Non HVAC + Architecture, MEPF, HVAC, Structural Major equipment positioning and location requirements, specialized service distribution and waste collection, e.g. medical gases and cryogenic pipe delivery, public transport and building inspection. This includes primary equipment neighborhoods and enclosures, barriers, pipes, venting and air inlet locations, and other restrictions. fa. Architecture / HVAC + Interiors: Connections include ducts and piping + ceilings and furniture, fixtures and fittings (FF&E) + HVAC. salt. Outer space validation: there will be no space gaps. The bounding boxes used to represent rooms and zones should be compatible with the architectural requirements and data values, and all should be coordinated with the values ​​specified in the Design Program. h. General model quality check: All walls should be properly connected to prevent “space leakage” in areas defined by wall surround. Bounding boxes cannot conflict. I. Security: security failures + structure + site. j. Regulatory Compliance: Wheelchair lanes and clearances + structure. (When using a rule-based model, proofing software such as Solibri Model Checker can be automatically checked for availability compliance.)

7.6.2 Building system design: BIM is used in the following cases: a. Modeling complex building systems, such as formwork and scaffolding, to improve planning, construction efficiency and safety. b. Modeling to improve buildability and assembly time through modular design components suitable for off-site construction.

7.6.3 Digital Manufacturing: The collaborative process can ensure that the manufacturer's knowledge and related performances are embedded in Design Models. Indicate in short the BIM project which of the following constructions the professions aim to provide 3D production models with parametric model objects: Steel structures. b. Mechanical piping system. down. MEP subcontractors (enable vendor models if available). re. Curtain walls. to me. Building envelope systems (rain covers, prefabricated panels, glazing systems). fa. Any additional production models generated by subcontractors.

7.6.4 Construction Schedule Planning and Sequencing - 4D: For design work that includes renovation swing sequencing or master planning for long-term development, 4D BIM is used to illustrate a plan for the stages of interaction, communication and final design approval and spatial sequencing with building occupants.

7.6.5 Construction Schedule and Sequencing Communication - 4D: The contractor will link BIM to the project schedule as a communication method to coordinate with the building's users and Facility Manager, where designated, in terms of logistics that affects existing building operations or requires the closure of any facilities and the affected tools. The animated step solution plan should address issues such as swing during construction, parking interruptions, and pedestrian / car rerouting, traffic or other construction activities that may affect construction operations. It is recommended that the Contractor also use BIM-4D in scheduling planning and communicating with the subcontractor and understand the impact of other changes on the construction schedule during the project.

7.6.6 Site Use Planning: Use 4D BIM to model permanent and temporary on-site facilities, equipment and materials, and movement, including deliveries for planning purposes, and to communicate on-site activities to facility personnel and building occupants.

7.6.7 Elevator Planning: The model can be used for planning engineering cranes, ie lifting large or heavy building elements and assembled on site. Elevator plan models can be created in collaboration between a structural engineer and experienced facility personnel, such as a crane manager, and used to communicate the elevator plan to those involved in its execution. The 3D model communicates the plan clearly to service personnel who may not be proficient in English or English reading 2D plans or written instructions. Elevator plan models should include: a. Location of cranes, hoists, rigging etc: b. Location of lifting team members. down. Pick up and set aside areas. re. Lifting paths and load rotation. to me. Boom angles. fa. Crane boom and clearances between other cranes, building components, obstacles and hazards (power lines etc.).

7.7 Facility management / As-built models: The as-built model with information captured during the design and construction phases can be a valuable resource in the operational phase of a project, if the data is in the right format. Define the object management requirements to determine what information to collect. Common uses include: a. Space management and tracking - space use, space allocation for building residents. b. Asset Management - Allocation and tracking of furniture, fittings and fixtures. down. Maintenance planning. re. Building system performance analysis. As a minimum, facility management information should be digitized and organized and indexed in a clear, logical manner that allows information to be easily retrieved by anyone with basic computer skills using readily available software.

7.7.1 COBie / Commissioning: General Construction Operations Building Information Exchange (COBie) is a methodology for electronic submission of building completion information for facility management purposes. Spreadsheets for some systems are available for download. See www.wbdg.org/resources/cobie.php. Third-party tools facilitate the automatic creation and transfer of some data between BIM and COBie spreadsheets via Industry Foundation Class Files (IFC) as an intermediate step, and some BIM software may involve creating and uploading data to, spreadsheet directly, without using intermediate files IFC. Where possible automated measures should be used to create and fill COBie spreadsheets. Requirements Model and facility data for commissioning, operation and maintenance of the project should meet COBie requirements and should be submitted in accordance with commissioning requirements. The data expected from BIM facility handover should comply with the following standards: Uniformat, OmniClass, Geospatial, COBie and IFC Building Information Standards. COBie data in the form of an Excel spreadsheet COBie and related commissioning information are provided electronically in suitable formats for inclusion in power and / or a planned CAFM system, Computerized Management Maintenance System (CMMS), Integrated Workplace Management System (IWMS), management system building (BMS) or any other system recommended by the customer. The design / construction team should consult the BIM software vendor (s) for the most up-to-date COBie tools. However, the completed COBie worksheets will also contain some information that is manually entered into the electronic file because the information currently cannot be conveniently extracted from BIM or because it does not reside in BIM. The design / construction team is encouraged to provide as much information in the COB as is known to be a deliverable. The required worksheets in COBie are completed according to the LOD and design phases (See BIM Object / Element Matrix). • The design / executive team should send the latest version of the COBie spreadsheet with the others. Required outputs at each stage of the project. • COBie Type and Component sheets are required for documents shipped with construction documents. These fields contain the component name, description, and creation date. Hardware listed in the Project for Design (PFD) software exported from architectural programming software should be noted on the COBie sheet.

7.7.2 Other FM Information Transfer / Release Systems: General In the event that the customer and the BIM team determine that using the COBie system is not appropriate for the project, they will define the details required for facility management purposes and a strategy to deliver it. Requirements The proposed system development process covers at least the following considerations. Identification of facility management information required by end users. b. Organization and indexing of information to facilitate its retrieval according to the required search criteria. down. File formats to include. re. Applications required to access and / or manage information. to me. Required system functions and functions, eg. Ability to update information, create desired format reports, ability to integrate with building systems, eg. Building Management Systems (BMS). fa. The strategy of collecting the required information throughout the project and delivering it to the client at the specified time.

7.7.3 Safety Assessment and Disaster Planning: The as-built model can be used to assess the physical safety and survival of a facility. The as-built model can also be a useful emergency response planning tool, if handed over to emergency services. The model in conjunction with a building management system can be used to identify the nature and location of a building problem within the building and the best way to get there. The project team should work with local emergency service providers to establish their information requirements and agree emergency protocols. Record specific BIM uses for these purposes in the BIM Brief

8.1 General: BIM (s) should consist of objects and elements that represent the actual dimensions of the building elements and the construction equipment that will be installed in the project. Prior to modeling, BIM Manager will do this to collaborate with the design team to develop a model and model view extraction structure for the entire design of document files to ensure coordination across disciplines. This structure will be communicated to the client so that: Models can be recreated at a later date. BIM coordination requires the following model structure and functions. behind. The BIM manager will develop a floor height protocol so that the Technical / Commercial Discipline BIM can be modeled at the correct height. b. Clearance Reservations: All models should contain separate 3D representations of the required clearances for all mechanical devices for repair, maintenance and replacement, access to lighting fixtures, cable tray overhead access etc. These clearance / access models should be on separate layers for each transaction clearly labeled like. down. The graininess of the elements in the model should correspond to the proposed sequence of installation towards the side (e.g. more than one wall element for the entire floor). re. All 3D model files uploaded for collision detection must be "clean"; all external 2D and / or 3D references will be removed from the models. to me. When sending an email notification of uploaded files or any other project email correspondence, all email subject headings must be preceded by the acronym of the project name.

8.2 Subcontractor Coordination: Prior to installation, the Contractor will hold trade coordination meetings with subcontractors. The coordinated model will be used to review and optimize planning and installation in the field. Subcontractors must have natural persons involved, who can actively participate in the subcontractor's coordination process and make commitments regarding the schedule

9.1 Approved BIM Software for Projects: All BIM software used in a project should comply with the documentation in the BIM Shortcut for the project. To assess the suitability of the software for use in the project and any other than compliance with the criteria presented to the customer for approval. Object-oriented applications that conform to current industry interoperability standards and can be used in a collaborative environment are preferred. All software platforms should comply with: • Modeling software certified as suitable for use with the latest Industry version Foundation Class (IFC) file format available at the start of the project. • Modeling software certified as capable of exporting native files to the IFC file format without losing geometric integrity. • Commercially available model checking software that ensures the interoperability of different programs. Applications. • Traditional 2D documentation prepared with approved IFC compliant BIM software and plans, elevations, sections, schedules and details should be derived and fully coordinated with the coordinated building model. All other documents must be submitted in accordance with the requirements of the contract. • The BIM-based energy analysis software used should support IFC import or be the native format of the BIM model. IFC Compliant. The selection of energy analysis software will be based on the US Department of Energy (DOE) Recommendations and ANSI / ASHRAE 140-2007 (or the latest version) and are compliant with the Australian Code Board (ABCB) Protocol for Building Energy Analysis Software. • All BIM software support tools used to manage information directly related to the model, eg Database, Room Data Sheet management applications, should be configured and operated in a manner that ensures model integrity is not compromised.

10.1 General: a. BIM should be used for all building system design, development and analysis including, but not limited to, architectural, structural, mechanical, electrical, plumbing and fire protection, etc. as indicated in this manual. b. In the conceptual design, schematic design and project development phase, BIM technology should be used to develop and establish the performance of the building and the design basis according to the customer's standards. The model must be interoperable with analytical tools including but not limited to building envelope, orientation, lighting, energy consumption, building management system (BMS), renewable energy strategies, life cycle cost analysis and space requirements. down. When creating model objects, use BIM authoring software content libraries. Model objects should contain parts and components as opposed to simple 3D geometry (e.g., walls, doors, windows, railings, stairs and furniture, etc.). re. Model objects should contain Industry Foundation Class (IFC) parameters and related data applicable to system requirements. These components support the analytical process including size, material, location, mounting heights and system information, if applicable. For example, a light fixture may contain several parameters such as energy demand, the user's lighting levels, brand, model, manufacturer, and bulb life. to me. The contractor will use the model geometry and extract the graphical information to generate the structure Administrative documents from the project BIM (RFIs, Curator's Instructions, Bulletins, Order Variants etc.). The contractor should register the as-built conditions with BIM as part of the final delivery to the customer. fa. The submitted drawings, calculations and analyzes should be downloaded from the coordinated BIM. salt. Elements, items and equipment should be tagged with global unique identifiers (GUIDs).

10.2 Types of model elements: The model elements come from the following sources: a. Producer Model Items Items created by manufacturers and purchased from manufacturers often have more information that should be preserved in the BIM model; an appropriate level of detail for the design element should be maintained. However, the embedded performance data should remain for analysis and specification purposes. b. Custom Model Elements The custom model elements you create should use the appropriate BIM Authoring Tool Templates to create custom elements. Custom model components must be assigned as part and part of a family or group.

10.3 Geographical position of the model: The spatial coordination (coordinates) of the main BIM file is established at the beginning of the project. Once upon a time, the established spatial coordinates will be changed only with the mutual consent of the team and the Customer Project Manager, with the issue recorded in the minutes of the meeting and BMP. Once the Project Coordinate System is set to Coordinate, each existing building model (s) relevant to the project will be converted to system coordinates used in each designed building. The geo-reference for locating the building accurately on the site and giving it the physical context of the location on a larger scale should be included in the BIM file. The BIM manager should develop geo-referenced site plans and building models for page layout overview and future use of the Geographic Information System (GIS) according to the Map Map from Australia (MGA) and Australian Height Reference System (AHD). The latitude and longitude points for GIS purposes will also be defined. The point of the BIM file and the latitude / longitude points must be at an agreed point on the site, i.e. easily accessible during construction and will not be moved. The MGA reference will always "read" as 0.0.0 - the project base point will read any distance from the MGA reference to the lowest point on the left side of the building framework.

10.4 Reference Points: The BIM Manager provides a 3D mesh for inclusion in the spatial coordination model. This will provide the browser with a quick reference when navigating in the model. Room information should also be registered.

10.5 Modeling space requirements: a. The method of measuring the floor area adopted in the project will be the kernel defining the space of the counting procedure for the client and constitute the basis of the Design Program (PFD). The method of measuring the floor area should be determined prior to modeling. See the Floor Area Annex for definitions and space measurements. b. The source will be space information imported from architectural programming software. PFD export creating space in BIM 1. down. Areas of 0.5 m2 or more should be tracked and identified by name, even if te sites are not listed in PFD Export Architectural Programming Software. re. Spatial data is generated and associated with the bounding elements (walls, doors, windows, floors, columns, ceilings). to me. When modeling each functional space, a defined PFD floor area measurement method should be used, using an appropriate BIM tool to capture and transfer information. Spaces should be represented and divided into functional spaces (e.g. office spaces, amenities, plant rooms) as defined in the PFD, even though they may be parts of a larger physical space. A physical space may contain several areas treated individually in the PFD spatial program. If two areas have a different functional space, the classifications, even if they fit in the same physical space, should be modeled as two separate spaces. For example, the security checkpoint areas in the lobby are modeled as separate items other than overlapping spaces. These spaces can also be grouped into a Zone for visualization and analysis purposes (e.g. for thermal simulation calculations). Users should consult the BIM authoring application vendor for a recommended method for creating space objects to be exported to Industry Foundation BIM class (IFC). fa. Plans and spatial / area diagrams should be dynamically updated from the model geometry. salt. The customer's spatial requirements should be verified with reports generated from BIM. 10.6 Metadata The BIM model (s) shall contain the following information: a. Project identification number. b. Project Name. down. Other information (building GUID, location, discipline owner, etc.) Necessary to allow specific software applications used in the project to run properly.

10.7 Space Naming and Coding: Each space should contain the following attributes that should be retained throughout the Design and Build of BIM models. behind. Building identification number. b. Wing (if applicable). down. Floor). re. Department (if applicable). to me. Subsection (if applicable). fa. Space name - English name and abbreviation. salt. Room Number - Wayfinding Room Number, h. Room Number - construction document number (if applicable. Used in large complex projects for contractor use). I. Space code - room code. j. Unique space number - 2k GUID. Space type by function - building information classification system. l. Space type by form - building information classification system. m. Measurement of space - use the defined measurement method adopted for the project.

10.8 Hardware Coding: Each individual piece of hardware, including mechanical hardware, should contain the following attributes and be maintained in all BIM models for design and construction: a. Course name - English name and abbreviation. b. Commodity code - equipment identification number 3. down. Unique item number - GUID. re. Element type (by function) - Building information classification system. to me. Item Tracking Number - Commodity identification number (if applicable. For specialized equipment). fa. Empty field for device type code or another (will appear later). salt. Other data available from Architectural Programming Software (APS), which is supported by the COBie Spreadsheet, if used, and is suitable for LOD at the assembly stage.

10.9 Additional Modeling Standards: In the absence of existing documented customer-mandated modeling standards, the BIM team will nominate from BIM the Modeling Standards to be used in the project. Any changes deemed necessary must be documented. Once BIM Modeling Standards and Revisions are agreed by the BIM Team, these will be adopted and managed to be consistently applied by BIM Manager. The BIM modeling standards cover at least the following: • Model configuration, including project templates. • Team member modeling protocols including definition of authorized uses. • Model naming conventions. • See naming conventions. • System naming conventions (services, etc.). • Element naming conventions (walls, partitions, doors, windows, etc.). • Conventions for naming materials and finishes. • Properties / parameters to consider for model objects. • Object property / parameter naming conventions.

10.10 Final BIM Elements: General One of the main advantages of the BIM model for the customer is that it is used to manage facilities after seizure. Information that matured during the build process should be captured in the appropriate models on the 2 Globally Unique Identifier (GUID). GUIDs must be preserved by generating and regenerating elements provided by IFC to thow was the object (space, equipment, etc.) can be properly tracked. GUIDs are automatically assigned by the BIM software. BIM See the software documentation to determine how copies of the hardware object instances in the reports output are handled and how they are handled internally in the software. 3 The item identification number will be used in the architectural programming software to associate the appropriate equipment with the appropriate room continuing through the construction phase. The use of these models is an evolving methodology, and different information formats are now required. Requirements At fixed times recorded in the project program, BIM files are summed up for the customer and cleaned up of foreign "scrap" or "workspace" layers, stories, abandoned projects, sites for creating and testing objects, blank layers, and other content that is typically produced during production BIM. Unless the project procurement strategy does not align these obligations, the client receives: 3D geometric elements - construction coordination model The contractor will be responsible for providing the client with consolidated as-built models for all construction systems. Model (s) should be fully coordinated and aligned with the Design Model for architecture and structure; the required instructions for configuring the files / folders should also be attached: 1. Contractor - Native file formats of the final Consolidated As-built Model (s) for building systems used in the multi-discipline coordination process (version agreed in BIM Management Plan (BMP). 2. Contractor - format IFC file (Consolidation Class) of Consolidated Building System Models (version as specified in the BIM Management Plan) 3D Geometric Elements - Design Intent Model The design team is to ensure that the intended design model remains current with all approved bulletins generally scope. that product-specific information will be added to this model Provide the model information for the architecture and structure teams and the required instructions for configuring the files / folders: 1.

Preferred standard: PDF / A-2. b. DWG (latest current version) format with associated views for each sheet. Delivering Digital Deliverables All digital products must be shipped on DVD / CD with clearly structured data and software versions labeled.

11.1 Project Folder Structure: Maintaining a consistent file naming and structure is critical to the proper functioning of linked files. Project teams and end users such as facility managers can download files quickly after the project is completed. For this reason, design and engineering teams should define a file protocol for the team when developing a BIM Management Plan (BMP). behind. BIM Folders - BIM files should be sorted by model files and sheet files. Model files - Original files from other disciplines should be linked to their discipline folder location and relative path to models. Model file names should follow the file naming convention described in the BMP.

Legal status of the design model to be built: • Binding: The imposition of a legal (contractual) obligation between the author (s) and recipient (s). When used in this context, do means a design model that represents what needs to be built according to the terms of the contract. • Informative: a design model that communicates non-binding information relevant to the project that may be useful to the recipient (s). There is no formal claim to its accuracy and is provided "as is". • Reference: Design model to be used for "read-only" purposes such as write model development at various stages of the design or clash detection. After designating models, "Reference", will not be further edited. Reference models can be used as the basis for bidding preparation, but cannot be part of the procurement documents. For this purpose, the "Binding" model must be determined - purpose, reason. Reference models must be sufficiently accurate for their intended purpose. • Reuse: design model authorized by the authors to be modified or further developed by the public.

Level of Development (LOD): American Institute of Architects Document E202 - 2008 Building Information Modeling Protocol The exhibition defines the level of development as follows: "The level (s) of development (LOD) describes the level of completeness to which a model element is developed." It describes the steps by which a BIM element can logically progress from the lowest level of conceptual approximation to the highest level of precision representation. The document defines the LOD as described below. Each subsequent level builds on the previous level and includes all the features of the previous levels. The defined levels (with associated content requirements) are: • LOD 100 concept: the overall mass of the building indicating area, height, volume, location and orientation can be modeled in three dimensions or represented by other data. • LOD 200 Approximate Geometry: Model items are modeled as generalized systems or assemblies with approximate amounts, size, shape, location, and orientation. Non-geometric information can also be attached to model elements. • LOD 300 Precise Geometry: Model items are modeled as specific assemblies accurate in quantity, size, shape, location, and orientation. Non-geometric information can also be attached to the Elements model. • LOD 400 production: Model components are modeled as specific assemblies, accurate in quantity, size, shape, location and orientation with complete manufacturing, assembly and detail information. Non-geometric information can also be attached to model elements. • As-built LOD 500: Model items are modeled as complex assemblies, real and accurate in quantity, size, shape, location, and orientation. Non-geometric information may also be attached to the model. Elements The level of development by definition applies to individual elements of the model. When describing a BIM model, it is generally assumed that all individual elements of the model have at least this LOD. In practice, strict consistency may not be necessary. A collaboration matrix or model progress specification as described in Document E202 describes how to determine the different detection levels required for model elements at each stage of the project.

15.1 Floor area: The purpose (s) for which the floor area will be measured, determine the appropriate measurement method (s) prior to modeling. Building surfaces are generally measured for three purposes: 1. To plan and evaluate the application. 2. In the case of the definition of rental and leasing. 3. For building analysis and comparison. Planning authorities in Australia have individual requirements for measuring areas in the city planning and building applications. As they can vary between states and territories, and between councils and authorities, you should check the measurement basis for each project with the appropriate authority. The measurement of the lease and lease area is generally calculated according to the Measurement: commercial or national measurement method as published by the Property Council of Australia. The floor area definitions below are for building analysis and comparison, and are abbreviated versions found in the Australian Institute of Surveying Institute's Area Book (AIQS). See full definitions. The unit of measure for each is square meter (m 2). Building Area (BA) The total area of ​​the building at all levels of the building floor, measured between the exterior walls of the surrounding walls. Total Floor Area (GFA) The sum of "Fully Enclosed Covered" and "Non-Closed Covered". The Totally Enclosed Area Covered (FECA) is the sum of all such areas at all levels of the building floor, including basements, calculated from a measurement from the normal inner surface area of ​​the exterior walls. The Unshielded Covered Area (UECA) is the sum of all such areas at all levels of the building, including covered balconies, open verandas, or attached open covered roads along buildings. Usable Area (UFA) The sum of the floor area measured at floor level from the total interior wall area of ​​all interior spaces related to the primary function of the building. UFA does not cover columns, service channels, service facility rooms, elevators, void spaces, amenities, service areas, and common areas, e.g. common areas such as foyers and hallways.

15.2 Measurement Procedures: Use an area measurement method that syncs practically with the main BIM creation tools. Area: BIM authoring tools allow you to automatically designate areas based on the surfaces of the surrounding walls that make up a polygon or based on a hand-drawn polygon. The areas of the included columns can be automatically subtracted in a flexible, size-dependent manner to obtain a usable area that meets the customer's definition. Manual area delineation methods are required to allow the use of centerlines of adjacent spaces allowing the corridor wall to constrain the space on the corridor side. Volume: The volume of space is determined manually and geometrically by specifying the surface area and assigning a height to it. Volume calculations in BIM do not change any of the existing Volume Guidelines found in the customer's documentation guidelines. Volumetric calculations may require some adjustments to the BIM design and plotted spaces, in particular with regard to multi-story spaces and void walls. As with BIM tools that create and place building elements, BIM "space objects" must be used as recommended by the BIM proprietary software if the volumes are to be correct, if the equipment location reports are to be correct, and if the exported IFC model is to be analyzed, aims to obtain correct results. For example, the amount of space occupied under a sloped building is typically adapted to accommodate the concepts of usable space. On the other hand, the hardware may take up space not otherwise counted as usable. The design team may consider this to be correct reporting goals, different categories of space covering almost the same volumes will need to be defined in BIM and informed wisely.
