Site layout plan for construction
Contents |
[edit] What are site layout plans?
Site layout plans are prepared by contractors as part of their mobilisation activities before work on site commences.
These are a crucial part of construction management, as sites can be very complex places involving the co-ordination and movement of large quantities of materials as well as high-value products, plant and people. Effectively and accurately laying out a site can help ensure that the works are undertaken efficiently and safely. Careful sizing and positioning of site facilities can help reduce travel times, congestion, waiting times, and so on, and help to make the site a more effective workplace with better worker morale.
[edit] How is a site layout plan prepared?
Site layout planning involves four basic processes:
- Identifying the site facilities that will be required.
- Determining the sizes, and other constraints for those facilities (such as access requirements, security, services and so on).
- Establishing the inter-relationships between those facilities.
- Optimising the layout of the facilities on the site.
As sites will change in nature during the course of the works, there may be a number of different site layout plans for different phases, and there may be more detailed plans showing particularly complex areas or sequences or describing specific functions.
The use of building information modelling (BIM) can help describe the construction site in three dimensions and through different phases, effectively creating a virtual construction model.
[edit] What should a site layout plan include?
Site layout plans might include locations for and sizes of:
- Zones for particular activities.
- Cranes (including radii and capacities).
- Site offices.
- Welfare facilities.
- Off-loading, temporary storage and storage areas (laydown areas).
- Sub-contractor facilities.
- Car parking.
- Emergency routes and muster points.
- Access, entrances, security and access controls, temporary roads and separate pedestrian routes.
- Vehicle wheel washing facilities.
- Waste management and recycling areas.
- Site hoardings and existing boundaries.
- Protection for trees, existing buildings, neighbouring buildings, and so on.
- Signage.
- Temporary services (including electrical power, lighting, water distribution, drainage, information and communications technology, site security systems, and so on)
- Temporary works (such as propping solutions for retained structures, sheet piling details, and so on).
- Areas for the construction of mock-ups for testing.
- Fabrication facilities.
[edit] Why is a site layout plan necessary?
Problems caused by poor site layout planning can include:
- Inappropriate storage which can result in damage to products and materials.
- Poor siting of plant.
- Poor siting of welfare facilities.
- Inadequate space provision.
- Unsatisfactory access.
- Security and safety issues.
- Poor way finding (due to complex layouts or inadequate signage).
- Demoralised workers, delays and increased costs.
