Question 1 - Specification section 02 82 11 paragraph 1.2 states that the quantities for abatement are on the drawings but the only drawing that mentions abatement is drawing ID1.0, The notes on this drawing say abate as needed. It does not confirm the presence of hazardous materials and it does not provide any way to calculate quantities for a fair competitive price. We request a hazardous material report or quantity information be provided.

Answer: See the provided ACM Sampling Reports for the Crawlspace and the remainder of the building. (See “BR-25-01”, “BR-25-Basement”, and “Pages from VA BHS Crawlspace Soil Sampling - B25”)

Question 2 - The scope of work mentions MEPS work but there are no drawings. Will drawings be provided so we can provide an accurate bid?

The HVAC Unit will be tied into this new panel. All remaining power for the space shall come from Panel “COPS” in Room 125B. Outages for this panel must be limited in number and coordinated at least 4 weeks in advance with the VA.

Answer: This Spec section was inadvertently included and can be ignored.

Questions 19: Per section 280500 it s tates that the Lynxx Panic Alarm System is to be duplicated, the Exacq Vision system it to be extended/relocated, the Hirsch Velocity system is to be duplicated. Unfortunately, these terms – duplicate, extended and relocated are not defined with specificity. Please detail what specific equipment is being relocated from one building to the other, what equipment should be purchased as new in duplicate, what equipment should be physically removed and re-installed at the new location. In addition, this specification s tates that there shall be no down time for these system but then states if there is downtime – it must be scheduled in advance. This is a contradiction – please confirm that down time is acceptable if scheduled in advance but more importantly how long each system can be “down” if scheduled in advance. This is needed for bidders to determine if a new equipment is required to maintain full operation.

Answer: Specification 28 05 00 Section 1.1C can be deleted in its entirety.

Questions 20:

Answer: Exterior Construction to infill the window shall be brick veneer. At exterior walls, the interior wall shall be reinforced CMU Wall per Detail 4, truss type horizontal reinforcement, full thickness Sound BATT Insulation, Metal Studs, and GWB.

RFI: Masonry

We noticed that the partition a t the interior that is the full length of the wall not jus t the window s ize .

Then noticed there was a partit ion type 5 where there is no infill.

Let me know how should carry these areas .

Question 21: Window schedule has windows A-D described as Double Hung Commercial Exterior Windows, with hollow metal frame to match Brockton Campus Bronze finish. I also found under "Painting Notes" it calls for Doors & Windows to be prepped to a Ballistic Level 5 Condition.

We installed all new Aluminum Windows around this building when we did the Courtyard with you guys.

1) Double Hung Windows are not available in Hollow Metal. Please clarify

2) Finish to match Campus would be Bronze Anodized (to match the windows we did). Hollow Metal frames do not come Bronze Anodized. Please clarify

3) Do the exterior windows need to be Level 5? If so, do we need to quote Ballistic Anodized Bronze Aluminum

Windows? Please clarify

Answer: VA requests aluminum windows per the Specifications. Aluminum windows are to match the existing windows on Campus. No additional ballistics requirements need to be met for the windows.

Question 22:

1. Plans indicate a symbol exists for which hardware set is to be installed on a par�cular door.

There is no such symbol shown on plans. Please advise.

2. The hardware schedule does not match listed door numbers. Addi�onal hardware & corresponding door numbers are required. Please advise.

Answer:

1. See sheet ID3.0 for hardware requirements.

2. See sheet ID3.0 for door requirements.

Question 23: Our subcontractors just provided us with additional RFIs, please see below.

1. Do any of the walls, doors, windows require physical security construction other than the holding cell and armory? – See Sheet ID3.0 for physical security requirements.

2. Are detention grade plumbing fixtures required for the holding cell? Is a lavatory in addition to the water closet to be provided? – See Specification 22 40 00 for plumbing fixture requirements in the holding cell. All fixtures are to be detention grade.

3. Please provide the elevations for the windows. – See Sheet ID3.0 Window notes for window elevations.

4. The SOW indicates to install a VAV system, however this is in conflict with the 3/1/24 HVAC Design guide which requires that HVAC systems be 20% more efficient that ASHRAE 90.1-2016. Please advise. – This design was completed prior to this issuance of the design guide. Contractors to provide what is shown in the design.

5. Can a VRF system be provided in lieu of the proposed VAV system. – No please install a VAV system as shown on the drawings.

6. Please confirm that adequate three phase power is nearby to support the proposed VAV system.

– The new VAV system does not need 3 phase power. The only power needed would be low voltage to control the damper and a reheat valve.

7. Please confirm the existing panels have enough capacity to support the proposed VAV system. – See the response to #6 above.

8. Please advise if the VA is providing the equipment for the CCTV, Security and other related access control for the contractor to install or is the VA providing and install the systems. – The GC is to furnish and install all materials related to the CCTV, Security, and other related control items.

Question 23: There are issues with the door schedule, drawing ID1.1, drawing ID3.0, and the door hardware sets listed on 08 71 00. They are not are not coordinated. The door schedule on ID3.0 has only door numbers 1,2, or 3 but the hardware schedule lists door numbers 101, 102, 103, 105, 106, and 105A.

• What do we bid? The plan or the hardware schedule in 08 71 00? What doors on the plan correspond to the door numbers in the HW schedule? – Sheet ID3.0 lists the required hardware for each door per room type.

• The door schedule on ID3.0 indicates there are 17 doors but drawing ID1.1 only shows (1) number 3 door, (3) number 2 doors, and (6) number 3 doors (10 doors total). The door schedule has (6) doors total. How many doors are we to provide? – Sheet ID3.0 has been updated to correct this discrepancy. [See “ID3.0_Schedules & Details_20240319”]

• The door schedule calls for security option SDO 228. What is this option? – See ID3.0 Physical Security Notes for SDO 228 information.

Question 24 –

1. Drawing ID3.0 calls for hollow metal windows but the specification includes a section 08 51 13 which is Aluminum. Also, the finish calls for matching Brockton Campus Bronze and the Bronze is an anodized aluminum color. We do not believe the hollow metal will meet the proper therms or U-value. Do you want Aluminum windows are we to provide the hollow metal per the drawings?

2. Also, do we need to provide blast resis tant frames or anti-terrorism frames?

Answer: See the response to RFI #21.

Question 25 - Are there specific requirements for the calculations for the roof HVAC?

Answer: Yes, calculations must be performed by a PE registered in Massachusetts.

Question 26 – Sheet ID3.0 states that a requirement of the holding cell is that “An observation window consisting of reflective glass protected by clear polycarbonate must be provided.”

Where is that to be provided?

Answer: This shall be installed in the door of the holding cell. The door shall meet the requirements of the design and specifications of the doors but should also be provided with an observation window. The window shall allow one way viewing from the corridor into the cell.

Question 27 – Can VA confirm the wall types at the Men’s Locker Room?

Answer: Wall types have been updated. [See “ID1.1_Floor Plan_20240319”]
