2 SCOPE SUMMARY

The following Purchase Description is for design, fabrication and delivery of a cold-formed steel pre-engineered metal building kit. Deliver all materials in kit to Mud Mountain Dam Fish Passage Facility, 25305 SE Mud Mountain Road, Enumclaw, WA 98022.

Submit a quote in response to this solicitation including drawings of floor plans for ground floor and mezzanine, elevation drawings from all four sides with details of finish and placement of components, and drawings showing the position and dimensions of structural members including isometric, plan and elevation drawings. Submit complete specifications with quote.

The minimum requirements listed in this Purchase Description must be met and specifications submitted with quote must indicate compliance. Dimensions and positions of components shown in the drawings included with this Purchase Description are advisory and your submitted quote may deviate from them to optimize for structural stability, constructability and user benefit in accordance with industry standards.

Submit stamped engineering drawings with calculations, concrete reactions and concrete anchor bolt layout with calculations and instructions for assembly no later than 60 calendar days after contract award. Deliver building kit no later than 4 calendar months after contract award to Mud Mountain Dam Fish Passage Facility and unload materials in locations indicated by government representative.

Design building strictly 50 ft by 50 ft at base, with eave height between 22 and 26 feet, and covered by gabled roof. Include a mezzanine and meet additional requirements in the Building Requirements section.

The building kit will be erected by government on an existing 6-inch-thick concrete pad constructed on subgrade of sandy gravel with silt and an assumed bearing capacity of 2,500 psf. The government will modify concrete pad as needed to accommodate reaction forces based on engineering provided by government after receipt of stamped engineering drawings, concrete reactions and concrete anchor bolt layout. Building structural members must be cold-formed steel to minimize modification to existing slab. Other types of structural members (hot-rolled, plate steel, red iron, etc....) are not acceptable due to the limits of the foundation and practical modifications. Building kit and all components must be capable of assembly without welding, brazing or other hot work.
