Introduction
Before construction work begins in an area of a project, the contractor shall submit to the project officer the design and planned installation of temporary walkways, covered walkways, roads, foot bridges, fences, barriers and other facilities required in the project. Approval must be obtained before work is started.

Phasing plans must minimize disruption to the NIH campus. Continuation of normal activity on the campus is of the highest priority.

Roads
Temporary closure of a roadway shall be allowed only after submittal and approval of a "Request for Temporary Use/Closing of Road/Parking Lot/Sidewalks or other Paved Area" permit. (Appendix A)

Weekend and night work should be performed whenever possible to minimize disruptions to traffic flow, providing noise and light pollution does not impact the neighborhood community.

Walkways
Existing walkways should be maintained in a usable and safe condition at all times, unless changes are approved by the project officer. Temporary closure of a walkway shall be allowed only after submittal and approval of a "Request for Temporary Use/Closing of Road/Parking Lot/Sidewalks or other Paved Area" permit. Proposed changes to existing walkways must include a plan for temporary walkways to re-route pedestrians around the affected area.

Signage
Construction signs must be limited to the minimum required but not exceeding the allowances detailed in Section E. Excessive signage degrades the appearance of the campus.

Office
Trailers Office trailers should complement the appearance of the campus and each other'. The exterior color should be white, beige or off-white. Multiple office trailers on a project must be of consistent style and color. Skirting will be installed to enclose the area between the trailer and the ground.
