Responses to Questions Received and Clarifications

1. QUESTION: Are there any Commissiong requirements? Section 019100 is not included in the Specification Manual. If required, will the Commissioning agent be appointed by the VA?

VA RESPONSE: Commissioning is not required

2. QUESTION: There is not a specification for Testing, Adjusting and Balancing provided in the Manual. Please verify that TAB will be needed and provide a Spec.

VA RESPONSE: Plumbing tests are specified in Section 22 05 11, Part 3.10. For HVAC, we understand that some supply and return grilles may be affected during plumbing installation. In such cases, the contractor shall ensure that airflow rates remain unchanged. To verify this, the contractor shall measure the airflow at all impacted grilles both before and after the plumbing work is completed. TAB Spec will be provided.

3. QUESTION: Please confirm that and all Basis of Design items and materials that the VA has satisfied all Buy American Waivers, if applicable, and sole source requirements as needed. Please provide us any Buy American Act Waivers that would be provided under this contract. This is not currently in the plans, documents, or specifications?

VA RESPONSE: No Sole source requirements or Buy American Waivers are required for this project. The basis of design is for reference only. The specifications are performance specifications.

4. QUESTION: Will the VA pay for the engineering and design submittals, as well as applicable deposits required by various manufacturers to put equipment into design and/or production?

VA RESPONSE: Payment for the project will follow work completed by an approved schedule of values and cost loaded schedule.

5. QUESTION: Is the new VA memorandum on bolts for steam and hot water systems applicable to this project? To our understanding A307 bolts are no longer allowed.

VA RESPONSE: Yes. The bolt specifications are for Master Specification Hydronic Piping (Specification 23 21 13, Section 2.3) and Steam and Condensate Heating Piping (Specification 23 22 13, Section 2.3). The sections are not in this project but still note that A307 bolts will no be allowed.

6. QUESTION: TAX Exemption: Is this project sales tax-exempt? If so, can the government provide a tax exemption certificate for materials purchased?

VA RESPONSE: This project is not exempt from the payment of sales taxes.

7. QUESTION: Notice to Proceed NTP) How soon after a contract award is the NTP expected to be issued.

VA RESPONSE: The issuance of the notice to proceed is contingent upon receipt of bonds, both performance and payment along with a certificate of insurance from the firm in which the project is awarded to. Once received, a notice to proceed can be issued within a week.

8. QUESTION: Submittal Platform: Will the VA accept use of Procore software or equivalent as the primary submittal platform?

VA RESPONSE: Yes, VA will accept the use of Procore software or equivalent as the primary submittal platform, so long as it meets the requirements outlined in the contract specifications, specifically 01 33 23-8 1.6.

13. QUESTION: Temporary Facilities: Are contractors required to provide a temporary site office or trailer, or will space be allocated withing the existing facility?

VA RESPONSE: The facility does not have a specific space internal to the building to set up a job office. As work will be conducted on night shift, parking will be better available in general parking areas at the facility. A location for a job site trailer can be coordinated with the COR, but the trailer is to be provided by the contractor.

14. QUESTION: Parking and Staging: Will there be designated parking and staging area for contractor personnel? How many parking spaces will be provided if there is on-site parking?

VA RESPONSE: As work will be conducted on night shift parking will be better available in general parking areas at the facility. Staging areas are limited at the Clarksburg facility. Coordination can be done to create space but is not guaranteed at time of bid.

a. VA RESPONSE: The work in Room 3B-151 falls within a patient risk group 2 (due to its location in a medium risk area adjacent to a waiting room). If the construction work takes only a day or two, it can be considered construction activity type B - small scale, short duration, and ICRA Class II. If the contractor determines that the work in this room will take a few days or longer: the construction activity type will need to be upgraded to type C, and the ICRA Class upgraded to type III. For either Class II or III, a plastic sheet barrier is acceptable. Plastic barriers must be affixed to the floor and ceiling and secure from movement or damage. If hazardous materials are encountered and need to be abated, the construction activity will need to be upgraded to Type D, and the precautions will need to be ICRA Class IV and a hard barrier would be needed.

a. VA RESPONSE: Drawing #EP100B – Unit # CAWTMS41, CAWTMS37 – Please disregard CA-WTMS-40, CA-WTMS-41 tags shown on EP100B. These are the existing water heaters. Mark CA-WTMS-37 is for the existing Water Quality Monitoring Station.

b. Drawing #EP100D – Unit# CAWQMS32 – Please disregard CA-WTMS-32 mark shown on EP100D. This is an existing water quality monitoring station.

c. Drawing #EP103C – Unit# CAWTMS34 – Please disregard CA-WTMS-34 shown on EP103C. This is an existing recirculating pump.

57. QUESTION: How proximate are the following groupings: Are they within 100-150 feet. Can they be wired to a single central location?

1-WTMS-1, 1-WTMS-2, 1-WTMS-3

1-WTMS-6, 1-WTMS-7, 1-WTMS-8

CA-WTMS-6, CA-WTMS-7

VA RESPONSE: Intuition 9 controller is indicated as a basis of design. An equivalent can be used in place of Intuition 9 that satisfies project requirements.

60. QUESTION: Drawing P-504 Note A states: This sheet is for reference only.

Drawing P-504 Note B states: Provide pre-tab and post-tab for the entire HVAC system after completion of work in the area where supply diffusers, or return / exhaust registers are being isolated.

Drawing P-504 Note C states: In lieu of pre-tab and post-tab, construct ICRA Barriers so that supply / return / exhaust diffusers/registers are located outside of the ICRA barrier.

For clarification, does for reference only mean that there is no work to be performed in regards to this drawing, if not see the below questions.

What is meant by the items in note B being isolated?

Will the whole system that the isolated items are connected to, need to have pre-TAB and post-TAB performed? Yes

VA RESPONSE: This sheet indicates the extent of each HVAC system in case a pre-TAB and post-TAB is performed.

Please refer to detail 1 / G-001. Where area of work includes any diffusers / grilles / registers, a pre-TAB and post-TAB will have to be performed on the entire system affected. Alternatively (note C), ICRA barriers can be installed in a manner so that the area of work enclosed by the walls and the ICRA barriers do not include any diffusers / grilles / registers. When no diffusers / grilles / registers are affected by the work, no pre-TAB and post-TAB is required. Suggested ICRA placement is provided on general sheets to avoid pre-TAB and post-TAB.

Please also refer to Sheet note A on G-003 throgh G-009:

A. USE A HEPA CART MOBILE CONTAINMENT SYSTEM FOR ALL ABOVE-CEILING WORK AND ALL AREAS OF WORK UNLESS OTHERWISE NOTED BY KEYNOTE 1 BELOW.

61. QUESTION: Drawing P-001 Plumbing Demolition General Notes #13 states: Unless otherwise noted, cut out indicated dead leg piping at limits of demolition and within two pipe diameters of the main/riser and cap waterside piping.
