9 Can the Government clarify whether final programming and commissioning of security and fire alarm systems will be performed by the contractor or VA personnel?

The contractor is responsible for all programming, testing, validation, and other tasks as needed to fully update all systems touched or modified under this contract.

Contractor to demonstrate that new equipment functions and operates as intended.

10 Will a TCLP analysis of the waste stream be performed prior to bidding? A TCLP analysis has been completed in the provided report for all known lead-based paint. A TCLP would need to be performed after bidding for unforeseen materials that are encountered during construction of similarly characterized materials. Please see Atch 21 - 02 82 11.1 Hazmat Survey Report and Atch 22 - 02 83 33.13.1 Lead Based Paint Survey 07-2006.

11 Is the intention to attempt to remove the lead-containing paint prior to demolition? It is up to the contractor’s discretion for means and methods for practical hazardous waste disposal. Submit a detailed plan for disposal for approval by the COR of lead contaminated wastes generated by this work in accordance with all applicable Federal, State and Local regulations. See specification section 02 82 33.13.

12 Are we to assume that all painted materials are to be disposed of as hazardous materials since the Hazardous Materials Plan notes that all paint on the corridor is to be considered lead-based paint? If so, was this assumption considered when establishing the Waste Management Plan goal of 75% recycled waste?

It is assumed that all paint in the corridor is considered to be lead-based paint.

Materials containing hazardous materials are not considered recyclable. The contractor is to remove any materials containing hazardous waste from the 75% recycled waste calculations. The contractor is calculate the 75% recycled waste based off only materials that do not contain hazardous materials.

CONTRACTOR QUESTION VA RESPONSE

13 What are the requirements for subcontractor employees to obtain the appropriate badge?

Specifically, are there disqualifying background factors such as felony convictions or other restrictions?

14 What depth and quantity of soil identified as lead-containing is anticipated to require excavation and disposal?

The lead containing soil is flaked off lead-based paint. Excavate and dispose of the top 6” of soil under the entire corridor to 1’ outside of the roof driplines.

15 Is the intention to perform demolition work during night hours or to utilize noise controls?

What noise-control measures should bidders include in their pricing assumptions?

This is contained within the noise control plan which dictates when night work needs to occur. Refer to specification section 01 57 19. 1.5. F (Noise management plan) and drawing sheet G-003 (Noise control and phasing plan)

16 It is mentioned that the contractor must allow access to the main door and sections of the corridor during demolition operations. What access constraints or sequencing requirements should bidders carry in their estimates?

Temporary access points and sequencing are described on drawing sheet G-003.

17 Sidewalk is very close to the B74 generator pad. Is there enough area to fit a 6’ wide sidewalk through this area safely?

Yes. There is adequate space to incorporate a 6’ sidewalk. There is also an added safety railing installed around the corner of the generator pad.

18 Conduits from B78 generator emerging in pull box and transitioning to conduit hanging on corridor lack information about what to do on ED106 and EP105. The assumed replacement conduits are not identified on EP106 conduit schedule.

New drawings are added to power building 77 and temporary buildings.

19 There appears to be an elevation change between the sidewalk and B78. Is there a ramp or stairs shown on the plans for this change?

There is no need for an additional ramp or stairs to accommodate the difference in elevation. Per sheet C-404, the sidewalk “ramps” up at a slope of 1:12 to meet the existing elevation of the porch at building B78.

20 Are the four construction phases required to be performed strictly in sequence, with each phase substantially complete before the next begins, or may abatement, utility relocation, temporary-access work, and other activities overlap between phases with COR approval?

Please identify any required phase acceptance, turnover, or hold points.

REF: G-003; SOW 5

As shown on sheet G-003 the phases are to be performed in sequence, but the contractor is to develop a phasing plan based off their means and methods for construction of the project. The contractor may perform multiple phases at the same time, if approved by the COR, without affecting the operations on the facility.

26 Please provide a building-to-building utility matrix for every corridor connection at Buildings 77, T-1, T-2, 78, 75, 69, 80, 68, and 74, as well as each continuous trunk segment between those connections. For each utility, identify the utility type, size and material, source, destination, upstream and downstream termination, active or abandoned status, buildings and operations served, criticality, isolation points, available as-builts or one-lines, and required disposition (remove, relocate, retain, cap, or provide temporary service). Include normal and emergency electrical power, fire alarm, communications/fiber/copper, paging, controls, fire suppression, steam, condensate, heating or chilled water, domestic water, sanitary or storm service, irrigation, fuel gas, and any medical oxygen, vacuum, or other medical-gas system. The plans do not appear to establish a definitive active-status and building-service breakdown for all corridor utilities. If the VA cannot provide complete details for any utility, corridor segment, or building connection, please identify each item that remains unconfirmed and explicitly state which utilities or segments the offeror must field verify. For each required field verification, identify the permitted verification method, required access or outage coordination, whether the verification is expected before award or after award, and the contractual bid basis and risk allocation for conditions that cannot be verified before proposal submission.

REF: G-001; V-101/V-401 through V-406; ED101/ED102; M/FD/FP Drawings; SOW 1-2

The Existing Conditions Drawings contain all of the existing information that VCI is familiar with. Contractor shall perform utility locates in areas of disturbance.

CONTRACTOR QUESTION VA RESPONSE

27 The drawings state that underground utilities have not been field verified and that additional unidentified active circuits may exist. Please clarify the required bid basis for utilities or circuits not shown in the contract documents. Will discovery, identification, relocation, temporary service, and repair of previously unknown active systems be treated as a differing site condition or contract change, or must offerors include an allowance in the base proposal?

REF: G-001 General Notes; Electrical Demolition Notes

Contractors are to perform utility locates in areas of disturbance.

28 Please provide, by building and utility, the allowable shutdown windows, maximum outage durations, minimum advance-notice periods, approval process, required temporary-service criteria, testing, and recommissioning requirements. Identify which outages must occur after hours and whether VA personnel must perform or directly supervise isolation, LOTO, valve operation, restoration, or startup. Specifically address continuity and risk allocation for Building 75 food-service refrigeration/freezers and potential food spoilage; any patient-care, 24-hour, VA Police, emergency-power, medical oxygen/medical-gas, fire-protection, communications, and security functions; and any temporary power, cooling, gas, water, communications, or fire-protection systems required before an outage may proceed.

CONTRACTOR QUESTION VA RESPONSE

30 Please confirm the required fire-protection impairment sequence at Buildings 68 and 74, including allowable outage duration, temporary protection, fire-watch requirements, ILSM requirements, testing, inspection, and restoration. Confirm who is responsible for scheduling and issuing system impairments and whether existing dry systems and porch-attic protection must remain continuously operational except during approved outages.

REF: FD107; FD108; FP101; PCRA Attachments

It is anticipated that the disconnection from the rest of the building systems can be done fairly quickly. The temporary shutdown for the systems for the buildings will need to be coordinated with the COR per specifications. A temporary fire watch will need to be performed by the contractor during the shutdowns if the shutdown is longer than one work shift. Contractor shall submit a request for scheduling system impairments for approval by the COR. There is no additional testing required prior to putting the systems back online since it is just disconnecting the parts of the system that are being demolished. Validation that the systems are still functional after bringing them back on line is to be performed by the contractor.

31 Specification 02 82 11 states that asbestos quantities are based on an August 4, 2006 MCS survey and a June 12, 2025 TRC survey. Please provide the complete reports, including appendices, laboratory data, sample-location drawings, chain-of-custody documentation, material inventories, photographs, limitations, exclusions, and any subsequent addenda. Confirm whether these reports and HA101 cover the full demolition limits, all corridor connections, concealed spaces, piping and duct insulation, utility chases, roofing, below-grade materials, and soil that may be disturbed.

REF: HA101; Spec. 02 82 11, Paragraphs 1.1.B and 1.2; Spec. 02 83 33.13

32 Please clarify whether the contractor must perform any additional pre-bid or post-award hazardous-material survey, destructive investigation, sampling, testing, or waste characterization for asbestos, lead, mercury, PCB-containing components, or contaminated soil. If required, define the scope, access, credentials, timing, quantities, reporting, and bid responsibility. Specification 02 82 11 requires the contractor to satisfy itself as to actual quantities and states that suspected RACM beyond the reports and drawings is to be identified and removed at no additional cost. Please reconcile that requirement with concealed or inaccessible conditions that could not be investigated before bid and confirm whether previously unidentified hazardous materials or quantities outside the documented survey limits will be handled as a contract change.

REF: HA101; Specs. 02 82 11 and 02 83 33.13; Hazardous-Materials Reports

The existing reports have been attached. If the contractor deems any additional testing will need to be performed, it will need to be included in the bid.

33 Please provide a definitive security-camera schedule identifying the required quantity, type, mounting location, pole assignment, field of view, and coverage objective for each Axis P3738-PLE panoramic camera and Axis Q1805-LE bullet camera. The material list identifies quantities as "as required," which does not establish a firm bid quantity.

46 How is any required emergency egress lighting being provided for buildings 68 and 69 following the removal of emergency power?

New general note added on EP102 and EP103 regarding additional emergency lighting with battery backup.

47 The plan to refeed Building 69 with two 6” conduits does not appear to be constructible as shown. Numerous pipe and equipment obstructions including asbestos insulated steam lines create conflict. Could the existing two 4” electrical conduits from the switchgear to the outside be reused? It could be feasible to place a pull box on the wall and run underground from just outside the building. See photos. Can the work at this building be accomplished without an extended power outage?

This was not the design intent, we will be reusing interior conduits but replacing exterior conduits to underground then have a transition to interior, this will be shown on the drawings and reissued.

CONTRACTOR QUESTION VA RESPONSE

48 With the removal of generator power, are any adjustments needed to support elevators in 68 and 69 during a loss of power, such as emergency lighting or battery lowering system?

New general note added on EP102 and EP 103 regarding additional emergency lighting with battery backup and elevator battery lowering system.

49 Please provide instructions for the disconnect on the south side of the east wing of Building 69. It is not rated for outdoor use. See photo

Disconnect will be replaced with equally rated disconnect but with outdoor rating. See attached ED105 & EP602.

50 Ensure update to ED103 to remove note that B77 power is underground and unverified This note has been removed

51 Reference EL102. Do not install lights on building 75 Lights have been added to poles and not onto the buildings. See attached EL102.

52 Is the intent that power to Building 69 as shown on EP103 is installed prior to demolishing this section of the corridor? How would the contractor hand dig through this area?

Have updated the drawings to route path alongside existing corridor for installation, and it will be before demolition. See attached EP103.

53 Clarify ED104 keyed note 3. Is this for the McQuay unit or the heat pumps? What is being installed underground? Is power being extended to the location to the southwest? Unclear intent

Clarified on keyed note, it is the heat pump. See attached ED104.

54 On Sheet E-504, please clarify keyed note 2. What is a “fiber optic power conduit?” Is there an intended distance limit for running power and FO in the same conduit? Unclear where the pull boxes are to be installed in relation to the junction boxes

Clarified on keyed note, intent was for both cables to be in one conduit. See attached E-504.

55 Detail C7 on EP106 shows a 24” depth to bottom of electrical conduits. Specification 26 05 41.3.3.B.1 and .3.a taken together appear to require concrete encased ducts for this project at a depth greater than detailed. Please clarify installation requirements for duct banks

24” in the detail is at the top of the concrete to match the specification, drawings now reflect. See attached EP-106.

56 Is there a requirement for the contractor to patch, seal, plug, etc. any and all gaps in wall partitions and exterior envelopes created by this project?

Yes, that is the requirement for the project for all disciplines.
