Appendix-G: Trailer Guidelines and Siting Procedures

1.1

General Occupancy Use Guidelines. Trailers on the campuses are appropriate only when (a) there is no practical alternative and (b) when there is a requirement for construction-related trailers, with a need for immediate proximity to a construction site.

1.2. Occupancy Use Guidelines Specific To Certain Trailer Types
  1.2.1 Construction contractor's field office trailers and (on large jobs) subcontractor trailers. Occupancy and use is under contractor control. Trailers are located within contract limits for construction site/staging area.
  1.2.2 Ready-issue materials storage trailers. There is no occupancy of these trailers. Use is under contractor control. Trailers are located within contract limits for construction site/staging area.
  1.2.3 Field support trailers for A/E or CQM contractors or NIH construction project staff. Occupants should be limited to those absolutely needed for daily on-site interaction. Trailers are located within (or near) contract limits for construction site/staging area.
  1.2.4 Office or laboratory trailers unrelated to a construction project. As a general policy, such trailers are not allowed. If an exception is sought, compelling cases should be addressed to the Associate Director for Research Services for consideration by the NIH Space Recommendation Board and subsequent siting by the Site Coordination Team. The request process is described in Attachment 2. This space is considered as temporary space as defined in the PHS Facilities Manual Vol. 1, Chapter 2-1 -10.E.
2. Trailer Siting Procedures. The selection of siting for trailers is established via the POR process or by sending a Site Selection Request to the Site Coordination Center. The request should be sent as soon as possible in the planning process so that site selection can be completed prior to the procurement process. Proposed trailer locations should be shown in accompanying documentation. Trailer site evaluation will include:
  2.1 Neighborhood impact. No trailers are to be located in the buffer zones as defined by the NIH Master Plans. The trailer site should have minimal impact on properties/roadways adjoining NIH. Impacts to be considered include visual, noise pollution, and traffic (location of entrances/parking).
  2.2 Emergency accessibly . Accessibility for Fire Department and other emergency equipment must be maintained.
  2.3 Site modification. The modifications required to make a site suitable for location of a trailer should be minimal. Unless part of an approved construction site, there should be no permanent landscaping impact (e.g. removal of trees or extensive regrading).
  2.4 Adjacency to existing structures. A minimum 40-foot distance should be maintained between the trailer and any existing NIH facility. In instances where this distance cannot be achieved, consultation with the NIH Fire Prevention Section (telephone 496-0487) will be required to identify additional fire safety features for the trailer and adjoining structures within the 40-foot perimeter.
  2.5 Utilities. Electrical, water, sewer, and telephone hookups should be available nearby, with minimal impact to local capacities.
3. Trailer Registration and Trailer Identification Numbers. All trailers including contractor-owned or leased trailers must be registered with the Site Coordination Team, which will provide trailer identification numbers. One number will be assigned for every trailer "structure," which may consist of several modular units. A numbering scheme will be used that identifies the trailer location with a nearby building (e.g. TR-49). If a trailer is moved to a new location, a new number will be assigned. The trailer identification number must be displayed at all times on a clearly visible sign near the main trailer entrance. Format of the sign (size, lettering) will follow DES standards. Trailer numbers will be retired at the time of removal and reused only if future siting presents similar conditions.
4. Operating Guidelines for Trailers.
  4.1 Sanitation services requirement. Custodial services in construction-related trailers are to be provided by the construction contractor as detailed in the DES Standard Specifications Section 01500 Series. Requests for custodial services in NIH leased or owned trailers (e.g. if approved as an exception under Section 2.4) should be addressed by memorandum to the Chief, Sanitation Services Branch, Division of Space and Facility Management. The following specific information should be addressed: Scope of work or description of housekeeping services to be performed; date or time frames requested for completion of work; total square feet to be serviced with copies of floor plans (when available); location of trailer and trailer identification number; proposed number of occupants; Common Accounting Number (CAN) to provide funding of requirement; contact person for coordination; and proposed period of performance (length of time trailer is expected to remain on site). A minimum of 60 days notice is required.
  4.2 Landscape Maintenance. Landscape maintenance around contractor-furnished trailers is to be provided by the contractor as detailed in the DES Standard Specifications Section 01500 Series. Landscape maintenance around NIH leased or owned trailers (e.g. if approved as an exception under Section 2.4) will be provided by the Grounds Maintenance and Landscaping Section (GMLS).
  4.3 Fire safe. Before a trailer may be occupied by a government employee, all items outlined in the DES Standard Specifications Section 0 1500 Series must be incorporated and approval obtained by the NIH Fire Prevention Section.
  4.4

Trailer Removal. Upon conclusion or termination of a construction project, a contractor controlled trailer must be removed from the site. All utilities must be shut-off, capped, and the site restored. It is the responsibility of the contractor to follow removal procedures as detailed in the DES Standard Specifications Section 01500 Series. The DES Project Officer will coordinate utilities shut-down procedures with the Maintenance Engineering Section. Any delivery or removal of a trailer that will involve the blockage of an NIH road, parking area, or walkway requires prior clearance by NIH Police and Fire Departments.
