Job/Site layout can be defined as site space allocation for material storage, working areas, units of accommodation, plant positions, general circulation areas and also access and egress for deliveries and emergency services.

It is imperative that every construction project should be organized and executed in the most economical and safest manner.

To aid on the smooth execution of the project, a job layout is prepared.

This a scaled drawing of the proposed construction site showing all the relevant features such as entry and exit points to the site, storage areas for materials, contractors offices, area keeping for equipments such as mixer, bar bending area, labour housing, toilets etc.

It is also necessity that first aid kits are kept in the site engineer’s office.

The following factors should be considered in preparing site layout:

• Nature, Scope and Type of work: - the nature of site layout depends majorly on the type of work to be carried out. E.g. the site layout for a dam would be much more complicated and extensive as compared to that of a residential building.
• Topography of the site: - the topography of the site i.e. location, size, nature of terrain etc. of the site also effect the site layout. E.g. the site layout in case of rocky mountains terrain would be vastly different from that in case of a plain terrain
• Methods adopted for execution of work: - the method selected for the execution of work deeply affects the nature of site layout e.g. if the work is carried out mostly mechanically i.e. using more equipment and less labour, more emphasis has to be placed on providing facilities for the machinery than for the workers.

The following are the advantages of a good job layout: -

• Smooth and economical working of the project
• Reduces the completion time of the project.
• Provides more safety in the working of the project.
• Material wastage and deterioration are reduced.
• Material transactions become easy, speedy and economical.
• Increases the output from labour and machinery.
