About this file
This document contains specifications for the construction of the Devils Lake Substation Stage 06 project in North Dakota. The project involves constructing steel structures, installing electrical equipment including transformers, circuit breakers, disconnect switches, current and voltage transformers, and capacitor banks. It also requires modifying existing steel structures. Estimated costs are provided for government-furnished equipment to be delivered onsite or by specified dates. The contractor must submit construction schedules and perform a post-construction survey. The NAICS code is 237130 and small business size standard is $39.5 million. The solicitation number is 89503420BWA000017 and was issued by the Department of Energy Western Area Power Administration for a project valued between $1-5 million.
