About this file
This is a Construction Bid Addendum No. 02 issued by the Michigan Department of Technology, Management and Budget (DTMB), State Facilities Administration Design & Construction Division for the Replacement of Backup Generators project at Alpena CRTC in Alpena, Michigan. The addendum addresses seven questions and answers received from bidders regarding generator specifications, concrete pad installation, fence modifications, and generator downtime requirements. Key clarifications include: concrete pads must be 8 inches thick (4000 psi with 5% air entrainment and 3lb/cubic yard TUF-STRAND SF composite fiber) without footings; a $5,000 allowance is included in the base bid for fence gate modifications; the maximum allowable downtime for backup power at each location is thirty minutes; and the contractor must provide one-half tank of fuel for each generator unit prior to startup. The bid opening date is June 17, 2026, with the bid due date remaining unchanged.
The addendum clarifies that the base facility has an 80kw generator (277/480v) in Building 490 and a 100kw unit (120/208v) available for temporary use during replacement, though staggered deployment may be necessary. Contractors must include rental and fueling costs for temporary generators at locations where base equipment is unavailable. Regarding existing equipment, the base will retain the 20kw (120/240v) unit at Building 490, while contractors are responsible for disposing of all other existing generator units. The professional contact is Mike Iott of Sidock Group, Inc., with Project Director Josiah L. Meyers approving the addendum on June 1, 2026. Bidders must acknowledge receipt of this addendum in their bid submission, as failure to do so may result in bid rejection.

Q1 - Who is responsible for the fuel for the generators?

Q6 - Will the base be able to provide temporary generators during the replacement?
A6 - The base has a 80kw, 277/480v generator currently installed in building 490, as was seen during our walkthrough. The base also has a 100kw, 120/208v unit available. This unit could be available for several locations, but they would have to be staggered. For all other locations, include in your bid the cost of rental and fueling as needed.
