This route is shown to run through the temporary mechanical enclosure west of B74, to be installed prior to the B74 West Wing demolition. It is our understanding that the temporary mechanical enclosure will remain in use until after Shop 06 vacates B74 which will not be until Phase 6. Please advise if this routing is to be revised to allow for installation of these utilities while the temporary mechanical enclosure is in place.

Routing will not be revised;

construction of mechanical utilities under the temporary mechanical enclosure will need to to be installed prior to temporary mechanical enclosure slab installation. Contractor to provide temporary caps as needed beyond footprint of slab.

For fans RF‐1, RF‐2, and RF‐3, all three fans operate at the same time, on individual VF drives. Per the sequence on drawing M‐706, if one fan fails, the damper for that fan closes, and the other fans increase speed to satisfy the air flow requirement. The fans are sized so that two fans can provide the full air flow and pressure required.

435 10/31/2018 RE DWG M709: M709 Shafts Area operating schematic shows a 3rd fan capable of an additional 100,500cfm over the requirement for the space. Is there anything in the control scheme that prevents the dust collectors and ducting system from being run over the specified air volumes? VLP operating scheme is the same.

Under normal circumstances, all three fans run at the same rotational speed to provide the required air flow rate, based on feedback from the air flow sensors. This will require programming the sequence of operations as written, into the control system. If one fan fails, its damper closes and the remaining two fans operate at higher speed to provide the required flow rate. This is the same control scheme as the air handlers, which have extra fan capacity and backdraft dampers in case one fan fails. The control sytem shall be programmed to not allow manual fan speed settings.

Please confirm that MERV 15 is acceptable for the primary/cartridge filters on the project. Also, please confirm if MERV15 is the minimum requirement for primary/cartridge filters

The Dust Collector Schedule on drawing M‐601 lists the final filtration requirement for the dust collector. If the dust collector has two stages of filtration, MERV‐15 is acceptable for the first stage. If the dust collector does not have a second stage of filtration, such as DC‐8 through 11, the dust collector will need to meet the MERV rating as scheduled.

440 10/31/2018 RE DWG M601: DC 1 thru 4, blast booth dust collectors state an air to media ratio of 1.8:1. This will result in a selction of a much larger dust collector than necessary for this application based on currently available technology. Can this AMR be deviated from?
