Specifications include, but are not limited to: 1) 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 envelope improvements, occupant safety improvements, environmental hazards remediation, mechanical improvements, electrical improvements, and especially energy efficiency improvements. CIHA will deliver to the Contractor a 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 repair 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 Residential Rehabilitation Program Manager a cost quotation of materials, equipment, testing, labor, permits, etc., work scope that will best accomplish the intended improvement(s). 2) The Contractor’s quote shall include specific make and model of major equipment, parts, and other materials to be included and the respective costs of each. Non-major repair materials may be lumped together as one unit. Generally, major equipment and parts cost $500 or more or are singularly crucial to the complete system's performance. An example of major materials to be used would include environmental air exhaust fans, controller(s) for such fans, lighting fixtures, light bulbs, service panels, motors, etc. An example of non-major materials could be electric cable, outlet boxes, receptacles, conduits, sealants and caulks, and so on. The Contractor shall also separately list: hourly labor costs, permit fees, inspection fees, and shipping costs, but may aggregate each category if more than singular. For example, several inspection fees may be aggregated and a single “Inspection Fees” listed. The Contractor may lump and list other costs such as copying, mail, etc., together and listed as “Administrative Costs” if not already included as part of material or labor costs. Together, all costs listed shall constitute the whole and total cost for the work required. The separate listing of materials, labor, shipping costs, and so on provides CIHA with a general history of the expenses. CIHA can then estimate future projects to determine the general magnitude of project costs. In turn, budgeting for the program’s life and number of dwellings to be served can be more accurately forecasted, resulting in better service to the community and the Contractors servicing this program. In addition to costs, the quote shall also estimate and list the number of days and/or hours anticipated to complete the quoted work, from arrival time on-site to time of final departure. CIHA will pass this information on to homeowners to prepare their schedules to be home while the work is being done. It is understood that estimated workdays are just that estimated, especially considering the unpredictable nature of retrofit work. This quote shall be provided to CIHA within one (1) working day after the site visit unless CIHA grants an extension. Waiting for cost and shipping information for materials/equipment not available locally could be a reason for an extension. Cost quotes shall remain fixed for a minimum of 30 days following submittal to CIHA. 3) The Contractor shall not limit their proposed replacement equipment/materials to only the makes and models of equipment the Contractor sells or represents. The Contractor is encouraged to offer alternative equipment, materials, and solutions to the work CIHA prescribed if, in the Contractor’s opinion, a safer, quicker, and a less expensive or equal alternative is available.
