Delivery of all required materials is required to be delivered no later than 60 days after date of contract (ADC).

• Vendor’s proposal must properly address each characteristic as evaluation criteria. Unless otherwise stated (i.e. range of values, minimum, maximum), the following specifications are mandatory. Pre- Engineered Building will come as a package unit (1 kit) of all components to construct this facility.

• Vendor shall provide column reactions to the 819th RHS in order for the 819th to accomplish the foundation design.

• Incorporate overhangs at personnel doors to minimize water infiltration into the building.

Dimensions for overhangs shall be 4’ x 4’.

• Column reactions should be sent to 819th RHS personnel ASAP so they can accomplish the foundation design in a timely manner.

• Note: All interior office/bathroom walls, electrical, water/wastewater, comm, and HVAC design, material, and labor to be completed by others.

• Include fabrication and delivery of a free-standing mezzanine: 65’- 6” length x 29’ width x 12’ clear height. This will have offices built by others underneath and above, so spans must be able to support this weight without the need for additional support beams in the center. The required live load for the mezzanine shall be 200 psf.
