25 C.F.R. § 256.19 – How are work plans prepared?

(a) First, a trained and qualified representative of your servicing housing office will visit your house to identify what renovation and or replacement will be done under the HIP. The representative will ensure that flood, National Environmental Policy Act (NEPA) and earthquake requirements are met, including the determination that the renovation or replacement is appropriately treated as a categorical exclusion.
(b) Second, based on the list of renovations or replacement to be done, your servicing housing office will estimate the total cost of renovation to your house. Cost estimates will be based on locally available services and product costs, or other regional-based, industry-recognized cost data, such as that provided by the MEANs or Marshall Swift. If the house is located in Alaska, documented, reasonable, substantiated freight costs, in accordance with Federal Property Management Regulations (FPMR 101-40), not to exceed 100 percent of the cost of materials, can be added to the cost of the project.
(c) Third, your servicing housing office will determine which HIP category the improvements to your house meet, based on the estimated cost of renovation or replacement. If the estimated cost to renovate your house is more than $60,000, your servicing housing office will recommend your house for replacement or refer you to another source for housing. The other source does not have to be for a replacement house; it may be for government-subsidized rental units or other sources for standard housing.
(d) Fourth, your servicing housing office will develop a detailed, written report, called a scope of work, that identifies what renovation or construction work on your house will be accomplished and how. The scope of work is used to inform potential bidders of what work is to be done. When the work includes new construction, the scope of work will be supplemented with a set of construction plans and specifications. The construction plans must:
1. (1) Meet the occupancy and square footage criteria in § 256.10 (d); and
2. (2) Provide complete and detailed instructions to the builder.
