Section E-1

Provisions for anticipated Temporary Services should be incorporated in the General Requirements of the specifications, but not in each product specification section. The responsibilities of each of the mechanical and electrical Contractors (or subcontractors) should be specifically defined where there are separate mechanical and electrical contractors, but not where work is under a single Prime Contractor.

When appropriate, the following Temporary Services should be addressed:

  1. Heat – as recommended in Section E-2
  2. Light & Power – as recommended in Section E-3
  3. Water supply – as recommended in Section E-4
  4. Barricades, Fending, Sidewalk protection
  5. Stairs, Netting and Planking for multi-story buildings
  6. Offices for field Superintendent/Inspector/etc.
