1. Site layout

This is a plan of site and area around it shows the exact location placing the resources of construction.

The job layout for a project depends upon various factors such as:

  • Nature of the project
  • Location of the project
  • Safety measure
  • Availability of materials and equipment
  • Soil conditions

2. Storing and stacking materials on site

Material on site should be stored so as to prevent deterioration or mixing with each other.

Following are of prime importance while storing materials

  • Should be protected from atmospheric agencies- rain, sun, etc.
  • Construction materials should be stored by adopting suitable measures against risks
  • Materials susceptible to fine should be stored so as to prevent fire hazards
  • Materials easily affected by moisture should stake on the platform with waterproofing

3. Preparation of actual job layout

Job layout is the first duty of the site engineer before the execution of work. A careful site layout /planning ensures:

  • Effective and efficient methods of works
  • Safety to workman and visitors
  • Avoid wastage and deteriorat9ion of materials

4. No interference or disturbance to adjacent facilities

The job layout in the site organization should consider the area available for:

  • Warehouses
  • Offices
  • Storage of materials
  • Equipment
  • Formwork
  • Bar bending space
  • Toilets
  • Entry and exit

Method Statement
