parking area. All debris shall be removed from the NIST campus.
Contractor shall field verify all dimensions noted herein and on all contract documents. The word trailer
and building are used interchangeably in this SOW.
1. Location
The project and modular trailers identified as Buildings 412 and 413 at located on the National Institute
of Standards and Technology (NIST) Campus at 100 Bureau Drive, Gaithersburg, MD, 20899.

Building 224 / 226 loading dock driveway area.
2. General Information






Eight 12’ x 60’ modular / portable trailers configured end to end and side to side to produce two
separate buildings (blocks) with a 24’ x 120’ foot print.
Each 24’ x 120’ section is supported on 16” x 16” masonry piers.
The main steel beams under the trailer are 10” x3” x 3/16 I beam.
Cross members and other associated framing was not identified.
The trailers hitches lay under the edges of the trailers and are made from the same above 10” I
beam.
