For each specialty, please identify the required credential type, whether the requirement applies to the firm, individual personnel, or both, and when proof of compliance must be submitted.

See specifications for all licensure and certification requirements.

77 UPS system configuration for new data center:

Section 26 33 53 requires static uninterruptible power supply systems. Please confirm the required UPS capacity, battery runtime, redundancy configuration, and physical arrangement for the new data center UPS system. Please also confirm whether the UPS is ownerfurnished and contractor-installed or contractor-furnished and contractor-installed, and identify whether a maintenance bypass switch and static bypass are required as part of the base bid.

UPS is contractor furnished and contractor installed. UPS capacity, runtime, configuration, and arrangement shall be as shown in the contract drawings and specification 26 33 53.

78 Surge protective device locations and ratings:

Section 26 43 13 requires surge protective devices.

Please confirm all required SPD locations associated with the new data center, MCR, and all new or modified distribution panels under this project, including the required surge protection category, surge current rating, and nominal discharge current rating at each location, so bidders can accurately price the complete SPD scope.

Reference electrical one-lines and panel schedule sheets for panelboards requiring SPDs.

79 Interior and exterior lighting scope:

Sections 26 51 00 and 26 56 00 require interior and exterior lighting. Please confirm the complete lighting scope for all new rooms, ICRA restoration areas, and exterior areas affected by the data center addition and tower construction, including whether existing lighting fixtures in all areas disturbed by construction must be replaced, relamped, or restored to match original conditions as part of the base bid. Please also confirm the required lighting levels for new data center, MCR, and telecom tower rooms.

Reference electrical plans for lighting requirements.

80 Security access detection scope:

Section 28 13 53 requires security access detection.

Please confirm the complete scope of security detection devices required in the new data center and all new telecom tower rooms, including motion detectors, door position contacts, glass break sensors, and duress stations.

The drawings and specs do include the complete scope for this section. Please see the TN sheets for ceiling mounted motion detectors in all TRs and the MCR. NO glass break sensors or duress staions are required for this project.

81 Security access detection scope:

Please also confirm whether these systems tie into the existing campus intrusion detection system or operate as standalone systems, and identify the responsible trade for furnishing, installing, programming, and testing all detection devices.

These motion sensors are to be tied into the eisting access control system.

82 Division 28 commissioning scope and contractor Deliverables:

Section 28 08 00 requires commissioning of electronic safety and security systems.

Please confirm whether all Division 28 systems, including PACS, video surveillance, intrusion detection, and fire alarm, are subject to formal commissioning under Section 28 08 00 on this project.

Please identify all contractor commissioning deliverables required before Government final acceptance of Division 28 systems, including prefunctional checklists, functional performance test procedures, integrated systems test procedures, training documentation, and commissioning reports.

Specification Section 28 08 00 does apply to all systems in the division 28 section. All commissioning requirements are contained in that Specification Section.

83 Micropile contractor qualifications and licensure Requirements:

Please confirm whether the micropile specialty contractor must be pre-qualified or submit documented experience on comparable federal, VA, or healthcare projects prior to award or prior to beginning micropile work, identify the minimum qualification requirements, and confirm the required state licensure for the Micropile PE of Record for this West Virginia project.

Contractor does not need to be pre-qualified., but must submit prior experience per the specs. Confirmed PE of record should be for West Virginia

84 Emergency generator capacity and load bank testing obligations for new telecom rooms:

Please confirm whether the existing campus emergency generator system has sufficient capacity to serve all new telecommunications rooms, the new data center, and all associated UPS, precision cooling, and life safety loads required under this contract in addition to existing emergency loads.

Please also confirm whether load bank testing of the emergency generator is required, the required duration and load percentage, and who is responsible for providing the load bank and coordinating the test.

Reference generator capacity and load information schedule on sheet EP701 for generator loading information.

Load bank testing is not required for this project. Contractor shall coordinate with the VA to determine if load bank testing is desired.

85 Legacy 110V telecom rooms:

Please identify each telecommunications room or space that requires legacy 110V distribution in addition to the standard 208V rack power arrangement so bidders can correctly size feeders, transformers, branch circuits, and device counts

Reference electrical details (EP500 series) for rack configuration and power requirements. Reference enlarged electrical floor plans (EP400 series) for quantity of racks.
