          TEMPORARY SERVICES AND FACILITIES



          It is extremely important during the planning of the construction project that all
          required temporary services and facilities are planned for to ensure that they are avail-
          able in a timely and sufficient manner to support the construction process. In order for
          a construction site to function properly, it must have access to water, electricity, and a
          sewer connection. Exhibit 6-17 is a checklist for temporary services. Prior to starting
          construction, the CM/GC should contact One Call in the area in which you are work-
          ing. (See Exhibit 6-18 for the One Call number in your area.) One Call will coordinate
          with the utilities, the marking out of all existing utility services coming in and out of
          the site, street and adjacent sites, and areas. This is imperative in an urban environment,
          where you have many utilities running below grade.

          Once all existing services are identified, then the CM/GC needs to contact all of the
          respective utilities and agencies to arrange for the securing of the existing services,  for
          those services that will be utilized during the construction process, and permanent
          services for the site. The following is a list of the utilities that should be contacted:
          1. Electric utility company
          2. Local gas company
          3. Local steam provider (if available)
          4. Department of water supply
          5. Department of sewers
          6. Local cable company
          7. Local telephone company


          An application to the appropriate utility along with an electric load letter (see Exhibit
          6-19 for a typical load letter) is often required by the CM/GCs and owner to arrange for
          the temporary and/or permanent services required for the project. It often takes quite
          some time to arrange for services from the utilities depending on whether the service is
          readily available in the area, the work backlog of the utility, the moratorium period
          during the holidays, and emergencies that the utilities may be facing. The orders must
          be placed as soon as the requirements are known.

          Once the utility services are provided to support the construction process, they need to
          be distributed within the site and building for use. The water service is secured with a
          valve at the foundation wall, with meters installed to measure consummation.
          Hydrostatic water pressure off the street mains is usually sufficient to allow water to
          rise to approximately the sixth floor of the building in most municipalities. To allow
          water to rise to higher levels, a pressure pump will be required. A hydraulic engineer
          should provide hydraulic calculations to ensure that an adequate quantity and pressure
          of water is available for construction purposes. Water will be needed for all temporary
          construction toilets on the site. These are normally located on the field office and shanty
          floors, along with approximately every five floors. Union jurisdiction and regulations
          of most construction trades working in urban areas will allow workers to walk up to five
