RESPONSES TRACKING SHEET PROJECT TITLE: EHRM Infrastructure Upgrades Construction

# RECEIVED ANSWERED CONTRACTOR QUESTION VA RESPONSE

1 Confirmation of Grounding Bus Bar Installation Responsibility (Section 26-05-26 – Grounding and Bonding for Electrical Systems)

(Drawing No. TG-100 – Item #6 - Typical Flush Outlet Mounting) Keynotes denotes Provide by Electrical Installer. We want to confirm the Electrical contractor will be responsible for the installation and testing of Grounding Bus Bars for all rooms and areas where required.

The General Contractor is responsible for all requirements under the contract documents. How they choose to sub-contract and assign the work is a means and methods question.

2 Confirmation of Outside Fiber Optic cabling type (Section 27-13-23 – Communications Optical Fiber Backbone Cabling)

Section 26-05-226, Part 2 Products, paragraph 2.2 states - Single mode fiber optic backbone cables are specified for inside and outside plant (OSP) use. We want to confirm outdoor armored rated fiber optic cabling is being specified here.

Confirmed, armor rated cables are required due to exposed routes through building crawl spaces. The alternative would require conduit runs through utility and crawls spaces.

3 Fiber Optic Site Plan (00-CG-001 to 00-CS-302)

Along with the provided site drawings, can any up-to-date information be provided on the conditions of the existing campus outside plant (OSP) backbone interbuilding pathways such hazards, flooding issues, structural stability, etc. for access points, manholes, crawlspaces, ducts, underground vaults, and conduits?

All available information is in the Bid Documents

4 Has the VAProgram Manager (PM) for the Murfreesboro VA (EHRM) Infrastructure Upgrade developed a system cutover and transition plan that will address the following:

1. Limitingand coordinating end-users’ and stakeholders’ outages and service interruptions.

2. Transitioning network systems hardware and components by sections, functions,operations, and

3. Having routine detailed pre-transition coordination meetings withend-users and stakeholders educating them on the upgrade and addressing their concerns and questions.

4. Ensuring infrastructure network systemtransitions are conducted outside of normal business operating hours such as weekends and afterhours.

5. Ensuring infrastructure transition prerequisites stepsare completed prior to cutover.

6. Ensuring system rollback plansare developed prior to any system transition.

This plan will be developed by local and National OIT support teams at a later date.

5 Drawings 001-T-11- through 001-T-151 have new data work are outlets (WAO) on them with the amount of cables to each one. Also Drawing # 001-T-405 has a list of all WAO locations with quantity of cables. The 2 items do not show the same quantity of cables to be installed. Which of the drawings takes precedence?

See bid schedule for quantities.

6 We respectfully request that the Government revise or clarify the evaluation language to account only for contractor-initiated cost growth when applying the 7.5% threshold.

Specifically, we propose that the cost growth calculation exclude the value of Government-directed changes, contract modifications initiated by the VA, or documented changes in scope requested by the owner.

The evaluation language will not be updated. An explanation can be added to the narrative portion of the proposal.

7 Background: Specification Section 01 00 00, par. 1.6.D.1 lists requirements for construction of temporary partitions and smoke-tight partitions. Question: Would the VA accept the use of STARC panels for temporary partitions in lieu of FR construction partitions?

101 Background: ICRA drawings and specs do not define fire rating for temporary barriers. Question: Please confirm the required temporary barrier type (1-HR rated vs. non-rated) for various room types, especially Telecom rooms adjacent to patient zones.

Rating requirement for temporary barriers are defined in notes 2 and 5 of G-031.

In accordance with NFPA 241-2022, 4.12.3, if construction requires the impairment of the fire sprinkler system, the temporary barriers shall have at least 1-hour fire resistance rating. Opening protectives shall have at least a 45-minute fire resistance rating.

If construction requires the impairment of an existing fire barrier, the fire rating of the temporary barrier must match the impaired barrier to provide a continuous rated partition. Opening protectives shall have at least a fire resistance rating commiserate with the rated partition.

If the fire sprinkler system is not impaired, and the construction does not affect a rated partition, the temporary construction barrier is permitted to be of non-rated non-combustible or limited-combustible material.

102 Background: Exhaust path guidance is not included where exterior access is limited. Question: What discharge locations are acceptable for HEPA-filtered exhaust when direct exterior access is limited?

Refer to ICRA permit application provided on G-030.

HEPA carts are required for Corridor work.

111 Background: Monitoring responsibility is not clearly assigned. Question: Who is responsible for maintaining air pressure logs and in what format must they be submitted?

The general Contractor to maintain and log daily. Logs to be displayed at the barrier entrance. Readings shall be included in daily reports.

112 Background: Specs reference HEPA filters but not certification process. Question: Is third-party certification required for HEPA filters, or are factory certificates sufficient?

Factory rating, verification by particulate measurement when required. See provided ICRA precautions for each Level of prevention.

113 Background: Specs do not clarify room-level vs. phase sign-off. Question: Will complete telecom rooms be signed off and released individually, or must they be bundled by phase/floor?

TR’s must be accepted by BUILDING/FLOOR as represented by cabling zone.

114 Background: Specs do not describe EMS cleaning coordination. Question: Is the contractor responsible for coordinating EMS terminal cleaning, and what is the inspection sequence?

Terminal cleaning when required will be scheduled by COR after final Contractor cleaning and VA acceptance for turn-over.

115 Background: Specs do not define allowed hours for containment setup. Question: Can containment barriers be installed during regular hours, or is after-hours work required for all such setup?

After-hour work requirements will be defined by hospital area. Not work type. Outpatient clinic areas will require after hour work for cabling and cut-over.

116 Background: Specs do not identify material requirements for protecting adjacent finishes. Question: Are specific materials required to protect existing adjacent ceiling tiles and flooring not to be demolished?

Material used for protection is a means and methods consideration. Any damage to the existing materials and replacement of damaged material is the sole responsibility of the Contractor

117 Background: Specs do not address obstruction of existing fire alarm devices. Question: Are temporary fire detection systems required if existing fire alarm devices are obstructed by containment walls?

Yes. In the event that the construction of containment walls obstructs existing fire alarm devices, the Contractor is required to relocate or provide new temporary fire alarm appliances to retain notification or initiating coverage. The Contractor is required to test the affected devices during the temporary and final installations.

121 Background: No protocol is defined for accidental dust/fluid releases. Question: What is the contractor’s responsibility if hazardous dust or fluids are accidentally released outside containment?

Protocols vary by released contaminant.

EPA, OSHA and VA Guidelines apply.

Immediate VA notification required for any event.

122 Background: Administrative zones are included but barrier requirements unclear. Question: Please confirm if infection control barriers must be fire-rated or just airtight in administrative zones.

Rating requirement for temporary barriers are defined in notes 2 and 5 of G-031.
