Rugged Base Performance Requirements ITMUS All Manufactured Homes

General

Manufactured homes to be procured under this contract will be used as part of the Federal Emergency Management Agency’s authority under Section 408 of the Stafford Act to provide temporary housing to disaster survivors. The Agency intends to reuse these manufactured homes to house disaster survivors in several disaster events. These units will be subjected to extended road travel (in excess of 6,000 miles over their lifetime), multiple installations and un-installations, and a wide variety of weather conditions. The manufactured homes must meet all of the requirements including having a complete Heating, Ventilation and Air Conditioning system and being furnished as described.

Legal Requirements

The manufactured homes (as defined in 24 CFR 3280) being procured using these Performance Requirements must meet and comply with all appropriate HUD requirements, regulations, standards, and guidance. This specification does not constitute any expressed or implied deviation from or waiver of any requirements of the U.S. Department of Housing and Urban Development (HUD) Standards, Regulations, or its amendments or interpretative bulletins thereof. These units must comply with HUD Standards, Regulations, and other appropriate HUD guidance and require a HUD Certification label to be placed as required in 24 CFR 3280.11 and a HUD Data Plate to be placed inside the unit as required in 24 CFR 3280.5. All units must comply and meet the HUD approval process. These specifications do not provide the manufacturer with a waiver of the approval process for receiving an “Alternative Construction Letter (ACL).”FEMA anticipates that the manufacturer will have to apply for one or more ACL to meet the requirements of these specifications.
