BIDDER QUESTIONS

Herman Miller Compass Typical VA Brockton (Remove mobile linen cart).

RESPONSE: Please refer to revised MD111.1 – Pipes indicate with the (E) CHWR, and (E) CHWS are existing to remain per the key located on M001

· RESPONSE: Yes, refer to keyed note 8 on drawing EY651. Existing fiber to be removed once new fiber has been installed.

· Half-shaded network jack is already a 4-port jack with (4) Cat6 cables/jacks. Fully shaded telephone jack is an additional single port faceplate, which should remain separate.

· Yes, devices designated with an “SM” indicates surface mounting. Provide surface mounted wiremold backbox and raceway stubbed above accessible ceiling, per Legend E-001. Raceway shall be metal.

· Yes, refer to keyed notes 1,2,7 and general note 2 for scope of work by contractor on drawing EY651.

· Refer to keyed notes 5 & 9 calling for CAT6A on drawing EY651. A specific manufacturer has not been provided. Cable should be submitted for final approval by SMRT and VAMC

RESPONSE: Please refer to the attached report titled “VA Brockton & Jamaica Plan Dust & Soil Rpt_FINAL-021716”.

RESPONSE: Specifications for the temporary trailer are provided in Specification 01 50 00. Temporary Facilities shall be a delegated Design based on providing the appropriate SF associated with the SF taken out of service during the renovation refer to GI004-GI010 for program requirements. The basis of design employed is based on the attached drawings provided by a local vendor see C1 and A1. The specific scope of spaces required may vary based upon the program required for each phase.

RESPONSE: Phase 0 represents any enabling work that can be performed at Level 0 that prepares Level 0 services with the subsequent phases for the floors above. If areas indicated for the floors above are not occupied, then this work can be phased during the duration of the specific phase. If the proposed phasing does not meet the intended schedule, or the current construction climate then the contractor shall provide a schedule that meets the criteria of maintaining continuous operation of the facility during construction. During the installation and preparation of the temporary facilities the long lead items can be identified and ordered. The bidding, design, approval and installation of temporary facilities shall take a considerable amount of time. All infrastructure work assumes the need for temporary feeds from temp equipment to meet the phasing and occupancy goals.

RESPONSE: See note above Q14 as well as Level 0 phasing for each subsequent phase. – if temporary cooling or heating is required to meet the intent of the project schedule this should be part of the proposed construction sequencing and associated cost. All infrastructure work assumes the need for temporary feeds from temp equipment to meet the phasing and occupancy goals.

RESPONSE: It is not the intent of phase 0 to swap out ductwork. Ductwork shall be per each individual phase. Please refer to answers in Q14, Q15. All infrastructure work assumes the need for temporary feeds from temp equipment to meet the phasing and occupancy goals.

RESPONSE: Please refer to answers in Q14, Q15, Q16. If a temporary air handler is required to meet the phasing and occupancy requirements then this should be included in the contractors bid clarification as well as associated pricing. All infrastructure work assumes the need for temporary feeds from temp equipment to meet the phasing and occupancy goals.

RESPONSE: The intent is that in phase 0 that all horizontal runs are to be installed and prepared to receive vertical feeds as each phase is connected to the system. Please refer to answers in Q14, Q15. Q16, Q17. All infrastructure work assumes the need for temporary feeds from temp equipment to meet the phasing and occupancy goals.

RESPONSE: The intent is to install the new heating system while the existing remains in place. This will require on site coordination of between the two systems. It is anticipated that both systems can occupy space in the existing mechanical room. All infrastructure work assumes the need for temporary feeds from temp equipment to meet the phasing and occupancy goals.

RESPONSE: If temporary systems are required to support the new systems then this shall be included in the contractor clarifications and bids. The contractor can propose alternative locations if it meets the overall intent of the project scope, and schedule. All infrastructure work assumes the need for temporary feeds from temp equipment to meet the phasing and occupancy goals.

RESPONSE: New water service piping can be installed prior to the demolition of existing and the only down time would be the time to tie into the main, test the system and insure that water distribution system meets water quality standards prior to restoring this back to normal operations. All infrastructure work assumes the need for temporary feeds from temp equipment to meet the phasing and occupancy goals.

RESPONSE: That intent to install new piping to enable each phase is the intent. This work will require coordination between new and existing systems. It appears that there is sufficient space above the ceiling to accommodate new and existing systems. All infrastructure work assumes the need for temporary feeds from temp equipment to meet the phasing and occupancy goals.

RESPONSE: Disinfection is the intent for each phase in regards to turning over each phase. If the work associated with a new phase is isolated from the existing then disinfection would happen prior to turn over of the current phase. Any time associated with this requirement shall be coordinated with the building operations schedule.

RESPONSE: Much of the main waste piping is located in a sub-Level 0 area- pipe basement there appears to be sufficient space to run new systems without affecting the existing.

RESPONSE: As much of the existing sanitary piping is located in the pipe basement the demolition work associated with this scope could be accomplished during normal business hours as long as it does not affect the systems needed to support the services operating during each phase.

RESPONSE: Storm drainage shall follow the same phasing diagrams. Horizontal storm drainage designated to be replaced as part of phase 0 would be accomplished at this time and each subsequent phase of vertical risers. Final coordination of attachment of new roof drains to the vertical risers shall be considered as part of the roof replacement.

RESPONSE: E2 Telecom is the VA Brockton preferred vendor. However, any vendor complying with the specifications can be used.

RESPONSE: No, VA does not have the information for the UL listing for the existing lightning protection.

RESPONSE: New panel shall be fed from existing distribution panel ‘EQDP-LV’. Refer to panel schedule on sheet EP602.

RESPONSE: Fixture models shall be the same as ‘Type A’ and ‘Type D’ with an integral emergency driver.

RESPONSE: We do not believe there is existing cable tray in corridor ceiling.

RESPONSE: Provide J-hooks in corridor for low voltage cabling.

RESPONSE: New fiber is not required. Existing fiber runs from Building 2 into the basement of Building 5 the basement room is where the fiber is patched up to the 1st and 2nd Floor closets.

RESPONSE: CAT6A patch panels are provided by multiple vendors. Ortronics (Legrand) does make these.

RESPONSE: Contractor to coordinate with VAMC to confirm plenum requirements in certain areas of the building. Non-plenum cable is acceptable in non-plenum areas.

RESPONSE: Per the response to Q33, new fiber is not required to be brought back to Building 2.
