Summary

This is Addendum No. 2 issued by the State of Michigan Department of Military and Veterans Affairs for Project 2651524024, "Construct Perimeter Roads and Parking Lots" at Grayling Army Airfield (GAAF) in Grayling, Michigan. The addendum, issued April 22, 2026, revises and clarifies bid documents for a construction project involving perimeter roads, parking areas, and associated infrastructure improvements. The bid opening is scheduled for April 29, 2026, at 2:00 PM EST. The project includes two deductive alternates: Alternate 1 for a new military parking area and Alternate 2 for a new POV (Personally Owned Vehicle) parking area, with revised pavement quantities of 14,522 square yards for Alternate 1 and 10,041 square yards for Alternate 2. Revised drawings include sheets C8 (site and demo plan), E1 (electrical MV/communications plan), E2 (electrical plan), and E3 (electrical details).

Key revisions include the removal of switchboards (Section 262413) and replacement with rack-mounted panelboards (Section 262416), simplification of lighting control systems to utilize Square D 8903L lighting contactors with McMaster-Carr watertight NEMA 4 enclosures and Tork photocontrols rather than fiber optic systems, and clarifications regarding asphalt pavement entry drives for both deductive alternates. Concrete aprons at overhead doors of the new GAAF Readiness Center are specified as 18 feet wide by 20 feet deep, with double man door stoops measuring 6 feet wide by 8 feet deep and single man door stoops measuring 6 feet wide by 6 feet deep. The silt fence length is corrected from 4358 inches to 4,358 feet. Bidders must acknowledge receipt of this addendum on the Bid-Summary Sheet. The project design manager is Jon Jorgensen of the Construction & Facilities Management Office.

Martin Luther King Blvd. Rm. 321 State Unit: Dept. of Military Affairs Lansing, Michigan 48906-2934

SUBJECT: Construct Perimeter Roads Parking Lots - GAAF BID OPENING: April 29, 2026, 2:00PM EST

ADDENDUM NO. 2

TO: All Bidders

SUBJECT: This Addendum is issued to revise and clarify the following items regarding the bid documents:

REVISED SHEETS:

SHEET C8 REISSUED

SHEET E1 REISSUED

SHEET E2 REISSUED

SHEET E3 REISSUED

ADDITIONS & REVISIONS TO SPECIFICATIONS:

REMOVE 262413 SWITCHBOARD AND REPLACE WITH 262416 PANELBOARDS

QUESTIONS/ANSWERS, REVISIONS, & CLARIFICATIONS:

1. Question: Is there any additional contact info or specific part numbers for Lighting Control Panels? The phone number in the Spec is contact info for another company that now owns Park Detroit and can provide control cabinets similar to the rest of the Airfield. But they are not affiliated with Hirschmann that was called out in Addendum 1.

Answer: Lighting controls have been revised and fiber optic cable has been removed from the scope. Each circuit of light fixtures are to be controlled with a lighting contactor and photocell. Lighting contactor to be a combination 480V lighting contactor with hand-off-auto bypass switch Square D 8903L or equal. Mount contactor/switch inside a McMaster-Carr Controlled-Access Watertight NEMA 4 Enclosure Powder-Coated Steel, 24" Wide x 30" High x 12" Deep hinged door with keyed lock #7619K142 or equal. Route wiring in conduit from contactor to 480V Stem-Mounted Photocell with Swivel Arm Tork Photocontrol Catalog No. 2008 or equal.

Lighting panel/panelboard concrete pad sizes have been reduced as shown on revised drawings. (Refer to reissued electrical drawings E1, E2, and E3.)

2. Revision: Pad mounted switchboards indicated on drawings have been revised to rack mounted panelboards (Refer to revised electrical drawings and newly issued specification section 262416 Panelboards.)

3. Revision: Entry drives into deduct alternate 1 and 2 parking lots were not shown as shaded to indicate asphalt pavement on the original bid drawings. Entry drives into the deduct alternate 1 new military parking lot are to be asphalt pavement matching the rest of the parking military parking lot. Entry drives into the deduct alternate 2 POV parking lot are to be asphalt pavement matching the rest of the parking lot. (Refer to reissued sheet C8)

4. Revision: Sheet C8 previously indicated on the site plan legend “gravel” areas. This has been revised to state

“HMA pavement” matching the other sheets. (Refer to reissued sheet C8)

5. Revision: Civil drawing legends had shown proposed alternate 1 pavement areas as 10,041 SY and alternate 2 pavement areas as 13,979 SY. Alternate 1 pavement areas are revised to 14,522 SY and alternate 2 pavement areas are revised to 10,041 SY. (Refer to reissued sheet C8.)

6. Revision: Refer to the Legend on sheet C2. The silt fence length should read 4358’ not 4358”.

7. Revision: The 4 Concrete Aprons at overhead doors at the new GAAF Readiness Center adjacent to the military vehicle parking lot will be 18’ wide and extend out 20’. Double man doors will have stoops 6’ wide and extend out 8’. Single man doors will have stoops 6’ wide and extend out 6’.

ACKNOWLEDGEMENT: The acknowledgement for this Addendum shall be noted on the Bid-Summary Sheet.
