Addendum No. 2

State of Michigan Department of Technology, Management and Budget Ottawa Building-SIGMA Move to First Floor File No:171/26231.ABG October 16, 2026

TO ALL BIDDERS:

This ADDENDUM is hereby included in and made part of the Contract Documents whether or not attached thereto. All requirements of the original Specifications and Drawings shall remain in force except as noted by this ADDENDUM NO. 2.

THE PURPOSE OF THIS ADDENDUM IS TO ANSWER QUESTIONS RAISED DURING THE BIDDING

PROCESS:

GENERAL CLARIFICATIONS / RESPONSE TO BIDDER’S QUESTIONS

1. Question: Where is the IT room located for routing data cables?

Answer: There is an existing IT rack that shall be utilized for running and routing new services for this space. This rack is located in ELEC 113 (see attached schematic)

2. Question: Where is the FACP located?

Answer: See attached schematic. The existing FACP is located on the east side of the central core, one level below. Upper level ramp, room N204.

3. Question: Are we able to T tap on to existing fire alarm devices in order to add the new horn strobes and strobes?

Answer: Yes, there are new devices in new conference rooms. These devices are to be tapped into existing system. Existing devices shall remain unless affected by demolition.

4. Question: Do you know the dimensions of the existing coffin floor boxes?

Answer: The approximate dimensions of the existing coffin boxes are 12” x 4”. These dimensions should be field verified. The intent is to pull all new lines to accommodate the proposed design.

5. Question: Will all new floor boxes require a new core drill or saw cut in the floor to accommodate the installation?

Answer: Yes, all new floor boxes will require a new core drill or saw cut in the existing floor unless there is already an opening in the same location. All new boxes are shown on the plans. Existing boxes shall be utilized if applicable.

Ottawa Building-SIGMA Move to First Floor| October 16, 2026 Page 2 | 3

6. Question: On sheet E101, the floor boxes are indicated by a blue line. Can you confirm whether the floor boxes labeled JJ, with keynotes P3 and P5, will also require new floor openings?

Answer: Yes. Unless there is already a floor opening in the same location, floor boxes labeled JJ will require new floor openings.

7. Question: The current installed DDC system is never called out by name and it is important for me to know what system is installed so I can determine if it is an open system or if it is a proprietary system. I need to know if it is Niagara Johnson controls, Honeywell, Siemens, or anything else that may be installed.

Answer: The existing controls system uses Trane SC and is a BACNet system. Please see attached revised drawing for reference.

8. Question: In the specs under page 088000-6 (2,7), this section calls out for window film. I don’t see anywhere on the plans that designates where this would go.

Answer: Window film will not be required for this project.

9. Question: The plans do not call out for a glass type. I am guessing it is just ¼” tempered.

Answer: Please provide ¼” tempered unless directed otherwise.

10. Question: What is the height of the existing 5’x5’ ceiling grid?

Answer: 12’-5” above finish floor. Winning bidder shall verify as required.

11. Question: Will there need to be any reworking/patching/supporting of the existing 5’x5’ ceiling grid/tile where it is removed and where new walls are installed?

Answer: The design intent is to leave the existing 5x5 grid and tiles untouched during the construction process. New walls shall be constructed in a manner that if the new walls come down in the future, the existing grid and tile shall remain in place untouched.

12. Question: How much existing damaged ceiling tile should we account for the 5’x5’ ceiling tile? Do you know the manufacturer/model number of the existing?

Answer: If damaged during the course of construction, contractor shall use any salvaged tiles and use them to replace the damaged tiles if necessary.

13. Question: How much existing damaged ceiling tile should we account for the 2’x4’ ceiling tile?

Answer: If damaged during the course of construction, contractor will be responsible for replacing any damaged tiles as necessary.

14. Question: We are not seeing any fire alarm and Tel/data specs and who is responsible for this work? If it is the electrical contractor who is responsible for the fire alarm work, what fire alarm system is in the building?

Answer: The existing system is a Honeywell system. The electrical contractor shall be responsible for providing new devices on existing system.

Ottawa Building-SIGMA Move to First Floor| October 16, 2026 Page 3 | 3

15. Question: Door and window frames: I’m counting 10 door-frame assemblies marked HM-PT, plus the separate clerestory window frames. Should we also include repainting any existing door frames or exterior window frames? Please confirm that the sidelights and transoms are included as well.

Answer: To provide continuity, all existing doors/frames/side lights should be painted/finished to match the new ones installed.

16. Question: Scuff Master: The specifications include a Scuff Master coating system but I’m not seeing where it’s called out on the finish plan. Is it required anywhere? If so, could you identify which rooms or surfaces should receive it?

Answer: Please disregard section in specification that pertains to Scuff and Stain Resistant Systems.

This will not be applicable to this project. Revised specification shall be attached to this addendum.
