About this file

This is Addendum 1 issued by the Michigan Department of Transportation for Project No. 000575/15, a paving project at the Kalkaska Garage. The addendum, issued on March 22, 2018, modifies the original bid documents and specifications for the Kalkaska Garage parking lot pavement work. Key modifications include the removal of an embedded electronic sensor at the north entrance gate (requiring coordination with MDOT Electrician Kevin Tomich), clarification that contractors may peel back fencing to pave around embedded posts at the east entrance gate, and requirements for contractor responsibility in hiring independent testing agencies for density testing of aggregate, hot-mix asphalt (HMA), and subgrade materials. Additional provisions specify that HMA millings must be stored on-site west of the PITWS between the west fence and building, contractors may not perform work on Sundays, and contractors must contact the facility supervisor Bob Helsel at (231) 258-5611 prior to project commencement to discuss staging and facility usability. The addendum includes pavement core testing data from 15 test holes indicating existing pavement thicknesses ranging from 0.19 to 0.73 feet and gravel base thicknesses ranging from 1.02 to 1.63 feet, with removal quantities totaling 14,150 square yards of HMA surface, 3,165 cubic yards of excavation, and miscellaneous curb, bollard, and fence removal.

The bidding documents and acknowledgment of addendum receipt were required to be returned with the bid summary. No specific pricing terms, contract award dates, contract duration, or funding source information is contained within this addendum document.
