4 Storey Commercial Building Floor Plan Dwg Free Download !!HOT!!

Designed as free-standing buildings, Commercial Building plans accommodate various businesses and other groups. This collection of commercial building plans includes designs that have one or more levels. Most are designed to accommodate more than one business or tenant. Commercial building plans are available in a range of sizes, styles and design. Smaller designs may provide one or two units, storefronts, or offices while the larger designs encompass office buildings and floor plans that can accommodate a number of tenants. Strip Malls and Miscellaneous Commercial plans are related to Commercial Building plans.

Commercial buildings are built to satisfy a variety of needs ranging from medical offices and retail outlets to small businesses. With some commercial building plans, each unit within the structure offers its own entrance while others share a common entrance used by all tenants. From small businesses to commercial chains in need of satellite offices or medical professionals with their own practice, these commercial building plans accommodate a broad range of business needs.

The dominance of steel in the multi-storey commercial sector is based on tangible client-related benefits including the ability to provide column free floor spans, efficient circulation space, integration of building services, and the influence of the site and local access conditions on the construction process. For inner city projects, speed of construction and minimum storage of materials on-site require a high level of pre-fabrication, which steel-framed systems can provide.

In many large commercial buildings, a two stage construction process means that the tenant is responsible for the servicing and fit-out, and so the building structure has to be sufficiently flexible to cope with these differing requirements. Many smaller buildings are designed for natural ventilation and with a high proportion of renewable energy technologies built into them. Many solutions are possible using steel construction.

The commercial sector demands buildings that are rapid to construct, of high quality, flexible and adaptable in application, and energy efficient in use. Steel, and in particular, composite construction has achieved over 70% market share in this sector in the UK where the benefits of long spans: speed of construction; service integration; improved quality; and reduced environmental impact are widely recognised.

The overall building economics are fundamental on the rationale for using steel construction in the commercial building sector, where the market share for steel has been consistently approx. 70% for the last 20 years.

Recent cost comparison studies show that the building superstructure generally accounts for only 10% to 15% of the total building cost and that the influence of the choice of structure on the foundations, services and cladding costs is often more significant. For example, a reduction of 100 mm in the ceiling to floor zone can lead to a 2.5% saving in cladding cost (equivalent to 0.5% saving in overall building cost).

Therefore, best practice building design requires a synthesis of architectural, structural, services, logistics and constructional issues. Where this synthesis has been achieved, long-span steel systems with provision for service integration dominate commercial building design.

Long spans allow the space to be arranged to suit open plan offices, different layouts of cellular offices and variations in office layout throughout the height of the building. Where integrated beam construction is used, the flat soffit gives complete flexibility of layout allowing all internal walls to be relocated, leading to fully adaptable buildings.

Steel and composite structures can be designed to reduce the overall depth of the floor zone by integrating major services within the depth of the structure, and/or by achieving the minimum structure depth. This is important in cases in which the building height is restricted for planning reasons, or in renovation projects.

The anatomy of a commercial office building is a function of its size and location, and client and planning requirements. Some key aspects of building anatomy are described below. The common features that influence the building design are:

Commercial buildings in city centres tend to be relatively tall (6 to 12 storeys is a typical city centre project) because of the high cost of land and the confinement of adjacent buildings and utilities. Planning requirements have a strong impact on the building form and its architecture, and in many parts of the country, it is a planning objective that commercial buildings are required to generate a proportion of their on-site energy use from renewable sources, e.g. photovoltaics, heat pumps, CHP, CCHP, as in the Palestra building near Waterloo, London.

An important aspect of many modern commercial building developments is the need for retail space at ground floor, office space above, and in many cases, below ground car parking. This can lead to complexity in the alignment of planning grids from floor to floor. A common solution is to create a transfer structure at ground or first floor levels to optimise the space use above and below.

Services also tend to be complex and some form of combined structure-services zone is considered in the building design. Vertical services are routed at discrete points on plan and distributed horizontally through the building. Long-span solutions are commonly used in this sector in order to optimise the internal space use. The building facades and roof tend to be lightweight, such as unitised curtain walling or infill walls supporting metallic or architectural faade systems.

The requirements for access to the upper levels of tall buildings and for overall stability mean that the core area is a high proportion of the plan area and is generally located centrally on plan. The office space wraps around the core, and from a functional point of view, this space should be as flexible as possible. The main beams therefore radiate from the core and are supported on perimeter columns. The provision of natural lighting tends to mean that the width of the office space is limited to about 15m. Services emanate from the core and are distributed through openings in the structure.

Larger commercial buildings are often designed around an atrium, which provides natural lighting and circulation space for the offices around it. There are many examples of this form of construction, such as in Mid-City Place, 7 More London and Tower Place in London. The plan form of 7 More London (a BREEAM Outstanding building) is shown below.

The area of the building on plan tends to be large (over 1,000m2 per floor) and the atrium is often located centrally, or may form part of an extended entrance area. The atrium is designed as part of the whole building energy and lighting strategy, and also provides the safe means of escape in fire; therefore smoke control in the atrium is a crucial part of the design solution.For a building layout point of view, the commercial space is typically 15 to 18m wide around the atrium and the cores are located at positions dictated by means of escape in fire. Generally, a minimum of two cores, and often as many as four separate cores are required on plan in buildings with atria. The simplified plan form of an office building with a central atrium is shown.

Mixed use buildings can be designed so that the column grid is compatible with the different uses. For buildings over car parking, the column layout has to be compatible with the space below. A 7.5m column grid in one direction allows for 3 car spaces, and in the other direction, the column spans are typically 5m, 7m and 5m, or combinations of these spans. A clear span of 17m is therefore the optimum for both the car parking and commercial space, and this can be achieved in steel construction.

Alternatively in residential buildings over commercial or retail areas, a steel transfer structure may be designed above the office or retail space, so that the residential space may be configured optimally. The transfer structure is designed to support the weight of the building above and so the use of a lightweight steel structure above leads to direct benefits in terms of the size and complexity of the transfer structure. This is an important market for steel construction.

Foundations tend to be simpler than in city centre projects. Solutions such as pad footings under columns and basements are not common unless used to house services plant. In that case, the basement does not usually extend over the whole plan area of the building. Services are also generally simpler than in city centre projects, and a wide range of faade systems are used depending on planning requirements, ranging from ground supported brickwork to curtain walling systems, .

The choice of this system depends on the form and scale of the buildings. In most buildings up to 6 storeys high, steel bracing is preferred, although its location is strongly influenced by the layout of the building. V or K bracing using tubular sections is often preferred as it is more compact and can be arranged around windows and doors in some cases. X flat bracing is preferred for use in brickwork as it can be located in the cavity between the leaves of the brickwork. 2351a5e196
