3.4.2 BUILDING SYSTEM AND MATERIALS

The intent of this RFP is to allow the Contractor the maximum flexibility to design and construct this facility in an economical manner without sacrificing good engineering practices, quality materials and systems. The Government requires low or no maintenance finish materials to the greatest extent possible. Building materials as described herein for roofing, walls, ceilings, doors, windows and floors are minimum requirements and may require revision based on code compliance and criteria.

Design the architectural elements of this facility to withstand all site-specific environmental conditions such as wide seasonal temperature swings, local wind, rain, and earthquake conditions. All architectural features must be appropriately braced for anticipated seismic activity. The Contractor may propose alternate building materials to meet the facility’s requirements, but final selection of materials is subject to the approval of the COR. Consider economics not only in the initial acquisition, but also in the future maintenance of the materials, when selecting materials and building systems to be incorporated into the project. When requested, the Contractor must provide documentation demonstrating that a chosen alternative material is life cycle cost effective.
