About this file
This document is a Request for Information (RFI) response spreadsheet for an Indian Health Service (IHS) construction project in Fort Thompson, South Dakota. The solicitation (No. 75H70125R00076) is for constructing one duplex building with an option for a second duplex, set aside exclusively for Indian Small Business Economic Enterprises (ISBEE) under NAICS code 236116. The project has a 365-calendar day performance period and will be awarded as a Firm Fixed Price (FFP) construction contract using a lowest price technically acceptable (LPTA) evaluation method.
The RFI responses cover extensive technical details including specific construction requirements such as exterior wall sheathing (R6-Zip system), flooring specifications (LVP with minimum 12mil wear layer), window and roofing details, utility connections, and various material and installation clarifications. Key points include installing water and sewer services for two duplexes, using specific sheathing and air barrier systems, confirming interior finishes, and addressing numerous technical questions about framing, plumbing, electrical, and architectural elements. The project involves residential construction with specific tribal considerations, including application of Tribal Employment Rights Ordinance (TERO) fees.
