This is an Addendum No. 2 to bid documents issued by the State of Michigan Department of Military and Veterans Affairs, Construction & Facilities Office, for Project 2651522002 to construct tie-down pads at Grayling Army Airfield (GAAF). The addendum, issued on August 6, 2026, revises and clarifies bid document specifications prior to the bid opening scheduled for August 19, 2026, at 2:00 PM EST. The project involves constructing proposed apron pavement with tie-down pads and mooring points for aircraft. Key specifications include a two-lift bituminous pavement system (165 lbs/SYD per lift) over an 8-inch non-reinforced Portland cement concrete pavement base, supported by a 6-inch aggregate base course. The bituminous mix design requires PG 70-28P asphalt cement with a minimum stability of 2,150 lbs, 8-16 percent air voids, and 14.5 percent voids in mineral aggregate. Construction details include bituminous tack coat (SS-1h) application between pavement layers, restoration of disturbed areas with 4 inches of topsoil and turfing with Mixture B, bonded fiber matrix mulch at pavement edges, and mooring/tie-down point installations featuring 8-inch concrete pads with copper-clad steel ground rods and Shepard's hooks.

The addendum specifically revises pavement section A-A on sheet C-4 and updates the bituminous mixture table, incorporating changes from Addendum 1. Construction notes address the possibility of frost-susceptible materials within the proposed pavement areas, requiring proof-rolling with fully loaded tandem axle dump trucks and removal of soft, loose, or unsuitable materials with replacement using suitable on-site material. The bidder acknowledgement for this addendum must be noted on the Bid-Summary Sheet. No pricing information, set-asides, incumbent contractor details, or contract term specifications are included in this addendum document.
