About this file
This is Addendum No. 2 to the contract documents for the Kinross Correctional and NRT Facility Electrical Upgrades - Phase 2 project issued by the State of Michigan Department of Technology, Management and Budget, State Facilities Administration Design and Construction Division. The addendum modifies and clarifies the original contract documents for electrical upgrades at the Kinross Correctional Facility. Key modifications include adding two new line items to the base bid schedule for pad mount medium voltage transformers: a 225 KVA transformer for the Powerhouse/Steam plant (Item 12) and a 75 KVA transformer for the Admin building (Item 13), both requiring removal and installation of new units. Additional revisions include updating panelboard main circuit breakers to include LSI trip units per specification section 262416, and modifying multiple electrical drawings (E-200, E-201, and E-600) to reflect the removal and replacement of transformers T5 and T6, the addition of a new Incoming Utility Switch Cabinet #1 (IUSW #1), clarifications on medium voltage feeder installations, and updates to feeder tags for loop feeders from MVSW #5 through MVSW #7. The addendum was issued for bidding on August 25, 2026.
The base bid schedule includes 13 line items designated as lump sum (LS) work covering transformers and switchgear, miscellaneous electrical equipment, site restoration, electrical demolition, paint, concrete, arc flash work, mobilization, bonds, warranty, and as-built documentation. Two allowance amounts of $250,000 each are noted in the bid schedule for contingency purposes. All work must be completed in accordance with the original drawings and specifications except where specifically modified by this addendum, and all incidental items required to complete the modifications shall be included in the bid even if not explicitly described. Receipt of this addendum must be acknowledged on the Proposal Form by all bidders.
