DPW-24246- RFQ ISU: Repair Utility Tunnel Phase 2

The steam and condensate lines in the utility tunnel system on the ISU Campus in Pocatello need to be replaced along with the tunnels. The project phases will replace sections of the 60-year-old and heavily corroded steam and condensate lines, insulation, steam valves, and steam specialties. The 80+ year old tunnel structure is also in need of replacement due to deterioration of the

concrete. This phase will replace about 350 feet of tunnel lid, floors, walls and access hatches. New Communication boring banks will be installed with about 635 feet with 5 conduits and

1,000 feet with 2 conduits. New Idaho Power boring banks with about 1,540 feet with 2 conduits and 465 feet with 1 conduit. Additionally, for Idaho Power there is about 860 feet of trenched

work containing 1 and 2 conduits.

The Communication work will require the installation of both fiber and copper lines along with terminations. The switchover at various buildings requires coordination with ISU and their providers.

The anticipated project Overall Budget of $6,273,706 has been established for all construction, consulting fees, contingencies, testing, and other associated project costs. With the Overall Budget, the associated Construction Budget is $5,000,000 and the current Construction Estimate is $6,500,000. It is anticipated that additional funds will be added to the project to increase the Construction Budget to the Estimate. A complete construction cost estimate and construction schedule will be required following the CM/GCs review of the preliminary Construction Documents and must be updated throughout the Construction Document process.
