CIHA personnel will conduct comprehensive building science, building energy efficiency, and weatherization assessments on mobile homes, single-family homes, and multi-family residential buildings. Multi-family buildings range from duplex buildings up to 120-unit apartment buildings. After the initial assessment is complete, written work scopes of potential building improvements are drafted by CIHA. Work scopes may include building envelopes, improvements, occupant safety improvements, environmental hazards remediation, mechanical improvements, electrical improvements, and especially energy efficiency improvements. CIHA will deliver to the Contractor Proposed Work Agreement stating the intended scope of repair or replacement improvements for all upgrades. Proposed Work Agreements give general direction regarding the nature of the installation and repaid tasks required. For example, such work scopes could be: “install a new exhaust fan in the crawlspace along with required wiring, junction boxes, and electrical controls; “or “install all wiring, conduit, junction boxes, etc. required to power and control a new boiler installed by others.” The Contractor must then visit the specified building within three (3) working days to survey first-hand the intended work scope. The Contractor shall then provide CIHA’s Senior Manager, Construction and Residential Rehabilitation, a cost quotation of materials, equipment, testing, labor, permits, etc., work scope that will best accomplish the intended improvement(s).
