About this file
This file is a Technical Responses Q&A document for the EHRM Infrastructure Upgrades construction project at a VA medical facility in Philadelphia, covering Buildings 1, 2, 3, 21, and 30. The document addresses 100 technical questions and clarifications submitted by contractors regarding design specifications, materials, equipment, and construction requirements outlined in the 100% bid design documents.
Key technical requirements include: security systems featuring Avigilon H6a series dome cameras, Lenel LNL-M2220 and LNL-1320-S3B access control panels with LifeSafety power supplies, and an Avigilon NVR6-PRM-FIPS-FORM-D-160TB-NA video server; telecommunications infrastructure with Category 6A cabling, 48-strand OM4 and 24-strand OS-2 fiber optic backbone cables, and specific WAP reinstallation requirements; electrical systems including L21-20R receptacles for single-rack telecom room configurations with A/B power redundancy, split system HVAC units using A2L refrigerant, and fire protection systems classified as Ordinary Hazard 1 for telecom rooms per NFPA 13; architectural work including fire-retardant plywood (4'W x 8'H) mounted 16" above finished floor, vision lite doors (6" x 27"), and specific keyed note revisions and clarifications on finish schedules; and IT infrastructure modifications to the Building 2 Data Center involving new MDA cabinets in Row N connected to existing ED cabinets in Rows T, J, and G. Critical project constraints include construction restricted to 5pm-5am ET weekdays only due to occupied facility operations, with all materials removed and work areas cleaned by 5am daily, requiring five phasing zones and a 365-day period of performance under VA Infrastructure Standard for Telecommunications Spaces (ISTS) V4.0, June 1, 2023.

| Discipline | # | Question | Answer |
| Security | 1 | Access Control, Video and IDS equipment: Need Name brand of the Equipment installed on site today. | The current equipment is irrelevant, as we are using Pelco analog cameras that were discontinued decades ago. |
To align with the Avigilon camera project, EHRM rooms should be fitted with Avigilon H6a series dome cameras.
| Security | 2 | Existing security network rooms: If current security equipment lines/equipment are damaged/removed during construction, would that be considered part of this project to replace? | Yes, if contractor damages existing equipment during the installaition. |
| Security | 3 | Existing security network rooms: Can the exact Reader Model number from the manufacture be supplied to match the system on-site? | HID Signo Keypad Reader 40KHNKS-03-0004XR |
| Security | 4 | Existing security network rooms: Would the department owner of the security systems be available to go over system availability and connections prior to project starting? | Yes. We will also ensure that our onsite maintenance vendors Star Communication / Tri-M are on location to assist with technical details. |
| Security | 5 | Existing security network rooms: Can you supply information on existing panel capacity for Access, IDS and Video systems? | All panels, readers, power supplies are beyond service life and should be replaced with new equipment. Any new Access Controlled Door will require a combination of a Lenel LNL-M2220, LNL-1320-S3B and LifeSafety Power Supplies. |
| Security | 6 | Existing security network rooms: If any security system capacity has been reached or would be reached in some areas, would mitigation be considered part of this project? | Yes, if expasion or storage would be required to support the new equipment that would be included. |
| Security | 7 | Existing security network rooms: Based on initial design will changes in pathways be considered if it is found to be more advantageous to the security systems layout and possible be more cost effective? | Yes, but any deviations from the design would need to be approved by the design team |
| Multi-discipline | 8 | LAN Network: Can you provide a network map that indicates where that network is established? | TECH: The local network core is located in the Main Computer Room. |

Please confirm what the symbol represents if the sheet note already calls for the circuit to be fed by critical power. | No, the "E" Symbol is NOT a receptacle but represents Electrical Power Drop, one is for Magnetic Door Lock - See Keyed Note 2. The other power drop should have been for AC Power shown rough, not at specific location bc Condenser is outside and Evaporator is on the wall. See Equipment Data Schedule and Panelboard Schedules for Clarity. |
| Electrical | 35 | The Added Loads table for Building 30 on sheet 30-E-700 states that there is one (1) rack per telecom room, however, each TR is being provided with two (2) L21-30R receptacles, which is typical for a two (2) rack configuration. Please confirm if L21-30R receptacles should be provided or if two L21-20R receptacles should be provided. | The intent of the design is to support a single equipment rack per Telecom Room (TR). The two receptacles shown were intended to provide A/B power redundancy to the single rack, not to indicate a two-rack configuration. |
Accordingly, provide two (2) L21-20R receptacles per TR in lieu of L21-30R receptacles. The 20A configuration is sufficient for the anticipated single-rack telecom load while still maintaining the required redundant power arrangement.

| Discipline | Item # | Type | Division | Question | Column1 | Answer | |
| 1 | Rooftop Rigging | Div 05 / 23 | Setting the structural steel and CRAC units on the roof will require a heavy crane pick from the street level. Will the VA assist in expediting the necessary street closure/lane restriction permits with Baltimore City DOT, or is this entirely on the contractor? | Critical | |||
| 2 | Roof Warranty | Div 07 | Installing the new Division 05 rooftop steel requires penetrating the existing roof membrane. Who is the manufacturer of the existing roof, and who holds the active warranty so we can utilize certified installers for the flashing? | High | |||
| 3 | Phasing vs POP | Div 01 / SOW | The project requires 5 phasing zones, heavy 2nd-floor demolition, and long-lead rooftop CRAC units within a 365-day POP. Will the VA extend the POP to accommodate documented manufacturer delays for the HVAC and Electrical gear? | Critical | |||
| 4 | ICRA | ||||||
| Contradiction | 001A-P02a / SOW | Drawing 001A-P02a shows temporary poly access points, but the SOW requires ICRA levels from the bid enclosures. Will VA Infection Control permit poly access points, or are hard-wall anterooms strictly required? | High | ||||
| 5 | Firestopping Scope | Div 07 / SOW | The SOW mandates sealing "existing penetrations." Will the VA establish a fixed "Existing Firestop Allowance" (e.g., $50,000) to ensure all bidders evaluate this unquantifiable risk equally? | High | |||
| 6 | Fire Alarm Matrix | Spec 28 31 | Who is the proprietary incumbent Fire Alarm vendor for the Baltimore VAMC, so we may request a quote for the required programming and NFPA 72 matrix integration? | High | |||
