About this file

Written by GovTribe AI · Mar 11, 2026

This is a set of construction drawings and technical specifications issued by the State of Michigan's Department of Technology, Management and Budget for a steam tunnel repair and water infiltration remediation project at the Secondary Complex in Lansing, Michigan. The project involves comprehensive repair of concrete spalls and delaminations, structural steel stanchion maintenance, and water infiltration remediation within an underground steam tunnel system that serves multiple state facilities including the Police Training Academy, Michigan State Police Headquarters, Michigan Secretary of State Building, and other state operations buildings. The drawings detail repair locations across eight tunnel sections (Vaults 1 through 9) with specific repair items numbered sequentially, including spall/delamination repairs ranging from 1 to 60 square feet per location, stanchion base replacements, unistrut stanchion replacements, clean and coat operations on structural steel elements, and leaking penetration repairs. Construction is to be substantially complete by January 2027, with the project issued for bids and construction on February 26, 2026. The design incorporates the Michigan Building Code 2021 and includes three required engineered inspection phases: repair identification and boundary marking, repair preparation verification, and repair completion verification.

The work encompasses concrete reinforcement repair with specific splice lengths for various rebar sizes, temporary relocation of electrical conduit and cable trays to access degraded areas, hydraulic grout infill for leaking penetrations, and protective coatings for exposed steel. Repair quantities have been estimated based on visual inspections and sounding techniques, with final quantities to be determined during field preparation and verified by the engineer. Unit pricing for concrete repairs is to include costs associated with temporarily moving and reattaching utilities that obstruct work areas. The project specifically addresses corrosion of structural steel stanchions marked in the field with "CC" for clean and coat repairs, "BR" for base replacement, and "R" for unistrut stanchion replacement, with replacement members to receive a Perma-Green III finish or engineer-approved equivalent. All work must maintain tunnel cleanliness to allow unimpeded operations of the steam system, and contractors are responsible for any damage to lighting components, conduit, cable trays, pipe insulation, or other utilities encountered during repairs.
