Job layout and site planning factors

Job layout

Job layout (site layout) is the planned arrangement of temporary facilities on the site, such as the site office, stores, material stacking yards, workshops, labour camp, batching area, plant and equipment, access roads, water and power supply and the work area itself, so that construction runs efficiently and safely.

Factors to consider in site planning

1. Site features: size, shape, slope, soil, drainage, existing trees, structures and utilities.
2. Access and transport: entry and exit gates, internal haul roads, turning space for trucks, one-way movement.
3. Location of the permanent works: temporary facilities must not block excavation, future work or the structure.
4. Material flow: stores and stacks near the work point and the crane or hoist to avoid double handling; heavy and frequently used items nearest.
5. Equipment placement: cranes, mixers and batching plants placed to cover the whole building within their reach.
6. Services: water, electricity, sanitation, drainage and telephone for the site and labour camp.
7. Safety and security: fencing, a gate with watchman, fire-fighting points, safe storage of explosives and fuel, and clear routes.
8. Labour facilities: canteen, toilets, first aid, rest sheds and camp away from noise and dust.
9. Office and supervision: the site office with a good view of the works, close to the entrance.
10. Environment and neighbours: noise, dust and nuisance control, and local by-laws.
11. Weather: protection of cement and steel in monsoon, shade, wind direction.
12. Future change: space for expansion as work stages change, and the cost of shifting facilities.
