Ref: I 702 and 703 Is the location for the new MIL-Spec connectors added to the enclosures a firm fixed location or is there flexibility in the locations? (ref sheets I-702 and I-703)

Yes the locations are flexible as constructability is the major factor in the connector locations. All connector relocations will need to be submitted in shop drawings for review

Sheet 1-702 Details for

RIO 3

On Sheet I-702 the right side detail for RIO 3 does not reflect existing conditions and cannot be located as indicated. Should these be moved to the top of the enclosure?

Yes. Locations can be adjusted as needed and shall be submitted in shop drawings.

1-613 I-613 shows a breaker added for each new connector on Enclosure 37568.

Note A indicates this is not to be connected to a power source. The reference drawing on I-703 does not show where the additional 22 breakers are to be installed. Please clarify the construction of this rail as to if it is to be a single rail configured for 1 source, or split for the 2 existing incoming sources as well as the impact to the testing requirements if the work indicated in note A is not completed prior to the start of this contract and the devices powered from these breakers are not functional.

The contractor to provide and install all circuit breakers, devices, and associated mounted hardware and cables. Cables configurations shall be per each cable identification labels. The breakers to be installed in side 37568. All end devices to be connected by dedicated cables shown on drawings. RIO 37568 is existing (two sources) . The power is existing and available, it should not be an issue for conducting the functional test.

Modification of the existing Source of power upstream is not part of this contract.

40 95 00, Section 3.3.1 Per 40 95 00, Section 3.3 .1 describes full loop calibration back to the PLC and validated at the HMI, but NASA is responsible for the PLC and any modifications to it. Section 3.3.3 provides exclusions of responsibility for the contractor but does not exclude errors due to PLC programming, HMI displays, or functionality controlled by the PLC. Please clarify the extent of the Controls testing required for this contract (It appears to be the intent for this contract to test to a prefunctional test level) and extent of the responsibility for functions/operations related to the PLC and

SCADA.

Controls testing will be limited to a pre-functional testing (i.e.

testing of the individual components to ensure functionality within the requirements identified in the contract documents).

The contractor will not have any responsibility for the PLC and

SCADA.

40 95 00 section 3.4 Per 40 95 00 Section 3.4 This contract requests a step by step procedure for system start-up as one of the required items.

Drawing M-402, Note A, Note M-405 Note B

Is the contractor to use the existing supports on reloacted humidifiers? Is the same type of supports to be used on the new humidifiers? Note: No support details for humidifiers are shown on drawings.

If an existing humidifier is being relocated to the same location, then the existing support system may be re-used. Otherwise provide a new support system as indicated on the Humidifer Support Detail on drawing M-614 Detail MBW.

General Overall Phase 1 question

Please confirm during Phase 1 that there will be no work in the ECS building despite the many notes to the contrary on the drawings.

Only work that cannot impact the existing ECS can be included in Phase 1. Predominantly, this work is exterior of ECS building.

However, the contractor may identify work fronts that are believed to not have an impact to the existing ECS. The Government will review these work fronts and approval is required prior to start of work.

3.1.2.1 Joints second paragraph states “Piping systems rated at 350 psi and lower require butt weld joints made with backing rings”. If the welding is to be per ASME B31.3 normal fluid service or better then 5% x-ray at a minimum will be required. Weld joints with backing rings will not satisfactorily pass x-ray. Please advise

Radiographic testing per ASME BPV Code, Section 5, Article 2 does not require removal of backing. However, if radiographic testing is not feasible due to equipment limitations, ASME B31.3 allows the use of UT or in-process examination in accordance with paragraph 344.6 or 344.7, respectively.
