Site Layout & Phasing

Introduction

The subsequent is an optimum site plan and phasing construction scheme for the Mollstrasse/Otto-Braun-Strasse development, aligned with RIBA Stage 5 (Technical Design) and German BaustellV/DGUV regulations. The scheme maximizes efficiency by zoning storage, access routes, welfare facilities, and crane operations, and addresses CDM 2015 safety requirements. A logistics plan minimizes congestion, and security measures (hoarding, CCTV, fire points) ensure a safe worksite.

Phasing has a formal five-stage process, with the potential for concurrent work flows, early handovers, and risk minimization. Enabling works, substructure, superstructure, fit-out, and Soft Landings handover are some of the key phases, a system which ensures smooth transition to occupancy by user engagement, performance monitoring, and post-occupancy review.

Justified by safety, efficiency, and regulation, this proposal finds a balance of multidisciplinary coordination (QS + CPM) and RICS/CIOB standards to present a feasible, client-usable proposal. The utilization of visual aids ( 3D diagrams) and HSE-compliant temporary works policies gives it further strength.

Site Layout

Overview: The site layout must facilitate safe, efficient movement of labour, plant, materials, and waste. comply with CDM 2015 regulations.

Zoning

Storage Zones

Clearly marked areas for materials and equipment, separated and shown in site Layout.

Access Routes

Routes for vehicles, separate pedestrian walkways shown in Site Layout.

Welfare Facilities

Toilets, break areas, and first-aid stations placed near the site entrance shown in Site Layout.

Site Offices

Clear visibility of operations without obstructing vehicle routes shown in Site Layout .

Cranes/Heavy Plant

Strategically positioned to cover maximum area with minimal repositioning in Site Layout

· Logistics Plan will be followed for deliveries to reduce storage needs and congestion.

· Security & Safety: Temporary fencing ( Hoarding sheets ) , CCTV, fire points ( evacuation points ), and emergency exits clearly demarcated in Site Layout.

Justification

A good layout optimizes site efficiency, reduces double handling of materials, improves safety, and minimize downtime. It also reduces environmental impact through better logistics.

Site Phasing

Overview: Site Phasing breaks down construction process into manageable sections or zones, This enabling smoother coordination and potential early handovers.

Process

Phase 1 – Enabling Works & Site Setup:

Site hoarding, temporary utilities, welfare setup.

Phase 2 – Substructure & Groundwork's:

Excavation will be Split into quadrants to allow parallel excavation and foundation work.
Coordination with underground utility installation will be followed for smooth process.

Phase 3 – Superstructure & Envelope:

Zone-based construction method will be followed (e.g., East Wing then West Wing).
Early closure of building envelope to enable internal works.

Phase 4 – Internal Fit-Out & Services:

Wing by wing to enable staged commissioning

Phase 5 – Final Testing, Commissioning & Handover:

Follow the Soft Landings methodology for smooth transition

Soft Landings

The Soft Landings process is a framework developed to ensure a smoother transition from construction to occupation of a building, with a focus on improving building performance, user satisfaction, and lifecycle value. It is closely aligned with the UK Government’s policy on achieving better outcomes for public building investments and is incorporated into the Government Soft Landings (GSL) initiative.

Soft Landings Process for a Construction Project

The process typically follows these five key stages:

1. Inception and Briefing

Objective: Align project goals with client and end-user needs from the outset.

Appoint a Soft Landings Champion (usually from the design team or client).
Define clear performance objectives (energy use, comfort, FM needs).
Engage end-users and facilities management (FM) early.
Integrate Soft Landings into project brief and procurement strategy.

Deliverables:

GSL performance targets.
Stakeholder engagement plan.
Project Soft Landings strategy.

2. Design and Construction

Objective: Ensure design aligns with performance and usability goals.

Hold regular design reviews and value engineering sessions.
Model predicted performance (e.g., using BIM or energy modeling).
Incorporate feedback from FM and users into design choices.
Maintain a focus on it's build ability, commissioning, and operational needs.

Deliverables:

Updated performance tracker.
Design-for-performance documentation.
Commissioning and handover strategy.

3. Pre-handover (Commissioning and Preparation)

Objective: Prepare the building, users, and management team for occupancy.

Conduct full system testing and commissioning (e.g., HVAC, lighting).
Provide user training sessions and building manuals.
Carry out technical reviews to ensure design intent is met.
Simulate building usage scenarios and rectify issues.

Deliverables:

Handover documentation and user guides.
Commissioning records.
Operational readiness checklist.

4. Handover and Initial Aftercare

Objective: Provide support during the crucial first few weeks of occupancy.

Keep the design/construction team involved post-handover.
Monitor systems, respond to user concerns, and fix early issues.
Conduct on-site presence (typically for 4-6 weeks).
Adjust controls and settings for optimal comfort and efficiency.

Deliverables:

Aftercare reports.
Fine-tuned building systems.
Post-occupancy issue log.

5. Post-occupancy Evaluation (POE) and Long-term Aftercare

Objective: Assess building performance and make long-term improvements.

Conduct POE at 3, 6, and 12 months post-occupation.
Evaluate energy use, indoor environment, and user satisfaction.
Compare actual vs predicted performance.
Inform future projects through lessons learned.

Deliverables:

POE reports.
Lessons learned summary.
Feedback loop to design and FM teams.

RIBA Stage Soft Landings Activity

Stage 0–1: Define performance outcomes, appoint champion

Stage 2–3: Design review, engage FM, embed Soft Landings into spec

Stage 4: Commissioning plan, user training prep

Stage 5: Pre-handover tests, occupant training

Stage 6: Aftercare, fine-tuning, POE

Stage 7: Ongoing monitoring and lessons learned

Benefits of Soft Landings

· Improved building performance and energy efficiency.
· Reduced post-occupancy complaints.
· Higher user satisfaction and comfort.
· Better-informed design and FM teams.
· Optimized lifecycle cost and asset management.

Justification

Phased delivery supports resource management, reduces rework, and enables staggered commissioning, improving client satisfaction. It also helps in managing risks by limiting disruptions to ongoing phases.

This policy outlines the principles and procedures to ensure the safe planning, design, installation, use, and dismantling of all temporary works on construction sites in Germany. Temporary works include scaffolding, shoring, form work, hoardings, access platforms, and site accommodations.

The company commits to:

Complying with the BaustellV, DGUV regulations, and DIN EN standards.
Eliminating or minimizing health and safety risks.
Promoting a culture of safe practices through training, communication, and continuous monitoring.

This policy applies to all employees, subcontractors, suppliers, and consultants involved in:

Design and supervision of temporary works.
On-site erection and dismantling of structures.
Inspections and maintenance during use.

Baustellenverordnung (BaustellV) – Construction Site Ordinance, ensuring coordination and safety planning.
DGUV Vorschrift 38 – Health and Safety regulations for construction work.
TRBS 1201 & TRBS 1111 – Technical rules for operational safety and risk assessment.
DIN EN 12811 – Requirements for scaffolding.
