E. BIDDER QUESTION AND ANSWERS:

1. REFERENCE: Specification section 40 60 00

QUESTION: This specification requires filling the LH2 and LO2 system with liquid nitrogen to perform a cold shock test which will equate to pressures at the base as high as 150 PSIG. Please verify the fill/drain and vent systems are designed to host these pressures.

ANSWER: All of the stainless steel lines have been designed to handle the weight and thermal stress of cold shock with LN2. Do not cold shock the 18x20" aluminum double walled pipe by filling with LN2; instead perform a localized cold shock on any field welds on the 18x20 pipe by using an external containment tub surrounding the weld and filled with LN2, or a cooling coil, or a similar method to achieve LN2 temperatures for one hour. The maximum static pressure head at the disconnect flanges at the base of the tower is 86 psig, which is below the pipe MAWP. See cold shock static pressure head tab. The contractor shall submit their cold shock procedure per section 40 60 00, paragraph 1.2.

2. REFERENCE: Specification section 40 60 00 and drawings K0000079480

QUESTION: The mass of liquid nitrogen for cold shock will be significantly greater than gaseous oxygen, liquid hydrogen and gaseous hydrogen the piping systems are designed to

NNK15524039R

Amendment 000011

support. Is the design of the cryogenic systems shown on K0000079480 capable of supporting the mass of liquid nitrogen when filled during cold shock?

ANSWER: Refer to response to previous question (Question #1 above).


QUESTION: Section 40 60 00 requires the systems to be filled with liquid nitrogen. Recommend cold shocking the systems transfer and vent elements independently to establish a worst case stress environment and most realistic stress environment between the liquid and vent/drain elements. Is this acceptable?

ANSWER: Yes, but do not cold shock the 18x20 inch aluminum vent pipe.


QUESTION: Typically components except for welded in bodies are not to be subjected to proof pressure testing. It is unclear if the cryogenic components if included in the GFE are included or suitable for proof pressure testing. Are the GFE components as provided suitable for the specified proof pressure test pressures?

ANSWER: Not all GFE components are suitable for the specified proof pressures, such as pressure gauges, pressure transducers, and pressure relieving devices. Refer to component information. Non-suitable components shall be isolated from the system using existing shut off valves or by the disconnecting and capping of lines. These procedures shall be included in pneumatic proof pressure procedure submitted by the contractor per section 40 60 00, paragraph 1.2.


QUESTION: The filling of the horizontal single wall lines with LN2 will cause the pipe to temporarily “bow” due to piping cross-sectional thermal differentials; we assume the design has taken this into account and the subsequent non-axial movement will not damage the expansion joints, components, or support structure. Is this a correct assumption?

ANSWER: Yes. Refer to response to previous question (Question #1 above).


QUESTION: The table in paragraph 3.4.3.2 shows the horizontal support spacing for ¼” tubing to be a maximum of 42”. KSC-SPEC-Z-0008 allows a maximum spacing of 48” for ¼” tubing. Please confirm 48” is acceptable support spacing.

ANSWER: The table in paragraph 3.4.3.2 in the Specification is applicable only for the MLT. The sentence after the table tells the contractor to use KSC-SPEC-Z-0008 only for the MLB. Therefore, 48" is acceptable in the base, but 42" is required on the tower.

Amendment 000011


QUESTION: Paragraph 2.7 designates the type of acceptable hydraulic fluids to be utilized in the hydraulic systems. Are these fluids to be GFE? If not, please provide an estimated quantity required for the ML hydraulic systems.

ANSWER: Filling the hydraulic systems is not within the scope of this contract for the TVC Servicing System (THSS) or HAASP.

8. REFERENCE: Technical Specification, SLS ML GSE Installation, K0000231317-SPC, Section 41 24 26, Paragraph 2.7, and Section 01 11 00, Paragraphs 1.4.1.6 and 1.4.1.7

QUESTION: Paragraphs 1.4.1.6 and 1.4.1.7 do not include filling the hydraulic system as a part of the scope of installation for the TVC or the HAASP. Paragraph 2.7 states that “hydraulic fluid shall be provided”. Please specify hydraulic quantity and installation requirements.

ANSWER:

The specification shall be amended as follows:

K0000231317-SPC, Section 41 24 26, Paragraph 2.7:

This is notification as to what hydraulic fluid will be used in each system. This is meaningful mostly for seal material compatibility (Sections 2.8 & 2.9). Filling the hydraulic systems is not within the scope of this contract for the TVC Servicing System (THSS) or HAASP.

K0000231317-SPC, Section 01 11 00, Paragraph 1.4.1.6:

All pressure and leak testing for THSS can and should be conducted using dry GN2.

K0000231317-SPC, Section 01 11 00, Paragraph 1.4.1.7:

All pressure and leak testing for HAASP can and should be conducted using dry GN2.

ANSWER: Information is provided for routing purposes. Connection details will be provided and added to the contract at a later date.

27. REFERENCE: Referencing the GFE (Facilities TAB) and Drawings K0000232118 (ODMS Sheet 227):

QUESTION: A.) Conversions, Inc. (CI), is the O.E.M. for the SMIC and ODMS. Per the O.E.M. drawings, CI has noted that as part of the contract, the SMIC is to be fully functional, which would include connection to ODMS #16 for complete SMIC proper function. The mentioned CI supplied O.E.M. As-Built drawing shows this connectivity exists, however as the time of testing during the original contract, this was not completed or tested. Can NASA verify if this connectivity exists? If not, should this be included in the current scope?

B.) The GFE indicates (2) two amber beacons, and we assume these will be utilized for Units #17 and #18 in AB10? (See E below).

C.) For the above, the drawing detail for #16 shows two Amber beacons , one on the LVL 305 and one going ??? on the cabling?

D.) For unit #16, no previous Remote Area Display Unit (RADU) and cable were installed due to pending changes. Is this now in the scope of work since it is shown on detail 1? If so, the GFE does not show this provided, hence should the RADU and required interconnect cable be provided in the vendor scope?

E.) Detail 2 and 3 show “Amber and Red Beacon Cabling”. Since in item A above, only two amber beacons appear on the GFE, we assume these are the units to be mounted in AB10. Where are the additional Amber beacons and who will supply them?

NNK15524039R

Amendment 000011

F.) On Drawing K0000232118, Sheet 339 shows both NEW ODMS Unit #17 and Unit #18 and the ADP’s per NOTE. 1 being attached directly to the structure. The ADP’s may be attached in this fashion as indicated, while the ODMS Units #17 and # 18 may not be installed as indicated without consequences.

Background: Conversions, Inc. conducted extensive testing over a three year period, to insure that the ODMS systems would survive a launch and the associated shock and vibration experienced from ignition to lift-off. Conversions, Inc. manufactured modified (slightly varies from the standard NASA 80K drawing) Part Number: S21-SMF-021 shock frames for units # 1 through # 16 that mount to the structure and then have the ODMS attached. These new fabricated frames provided by Conversions, Inc. were specifically modified from the Apollo/Saturn era shock mount design to include advanced metal formed braces and brass helical wound shock absorbing coils designed to dampen the effects of a launch sufficiently to survive without unit damage. Keep in mind we have recorded shuttle launches (Note: 3 – engines and two solid boosters, while the new spacecraft will have more engines and an additional solid segment in each motor section) which then resulted in a maximum of up to 7.2G’s of sinusoidal vibration for from seven and up to a maximum of fourteen seconds in duration, depending on the direction orientation. I have attached one of the series of test charts dated March 6, 2006, for reference. Much of the individual industrial computer, LED color display, electronic, and electromechanical base ODMS components utilized within the enclosure have ratings of a maximum of 1G instantaneous shock (some are higher) and sinusoidal vibration of 1G or less for 5 seconds or less manufacturer’s “as-shipped” rating. (Note: the spring coils are long-lead time, and have a very specific specification).

Conversions, Inc. has taken additional design precautions to secure the hardware within the enclosure to insure reliability, however it is based upon the additional dampening and vibration reduction provided by the typical Conversions, Inc. tested and proven shock mount*. Has the addition of the required shock mount been included somewhere else that we have not located in the documentation? *Note, Conversions, Inc. has an O.E.M. drawing for the previously supplied Unit 1-16 mounts, Conversions, Inc. catalog Part Number: S21-SMF-021 shock frame, provided with inorganic zinc coated and ready for painting, or pre-painted. The S21-SMF-021 is provided with drawings indicating the additional contractor supplied wall mount hardware (not supplied) for wall mounting installed in the field.

G.) On ODMS Schematics, Drawing K0000232118, Sheet 227, Note 1 states AL6XN Tubing be provided. Due to a variety of reasons which I can answer separately, Specific Conversions, Inc. provided ODMS Nylon Type 11 tubing was utilized previously throughout the installation on ML1. The ODMS units currently have through hole standard recommended quick-release connectors for the Nylon tubing, and not rigid tubing. Conversions, Inc. will assist the contractor with the same fittings required for a complete and recommended installation when the AL6XN Tubing requirement is replaced with Conversions, Inc. provided ODMS Nylon Type 11 tubing .

NNK15524039R

Amendment 000011

Is Note 1 going to be corrected or retained as it exists? If the non-recommended tubing is retained, the ODMS shall require an additional transition for tubing types.

ANSWER:

A.) Per the sheet 227 (aka M-603) the ODMS unit #16 is not and will not to be connected to the SMIC.

B.) The 3 amber beacons are to be mounted over units 17 & 18 in AB-10 and above Unit 16 in the level 305 per Sheet M-310. The GFE list will be modified to 3 amber beacons.

C.) The 3 amber beacons are to be mounted over units 17 & 18 in AB-10 and above Unit 16 in the level 305 per Sheet M-310. The GFE list will be modified to 3 amber beacons.

D.) Per detail 1 on sheet M-603, the cabling will be installed to a bulk head plate for the Crew Access Arm (CAA). The RADU is not part of this contract. The CAA is not part of this contract.

E.) The 3 amber beacons are to be mounted over units 17 & 18 in AB-10 and above Unit 16 in the level 305 per Sheet M-310. The GFE list will be modified to 3 amber beacons.

F.) The ODMS units that are being furnished by the government will be provide with vibration isolation.

G.) AL6XN tubing shall be used up to within proximity of the ODMS unit and converted to a flex tube to enter the unit per details 1-3 on sheet M603 (aka 227).

QUESTION: The answer to this question per Amendment #8 clarified that “The 2" and 3" Venturis must be stainless steel. The 10" is FRP. 2" Venturi Model 20183-2, 316/316L SS. 3" Venturi Model 20183-3, 316/316L SS.” However, the manufacturer of the Venturi flow meters, is questioning the use of FRP for the 10” flow meter, based on their historical design discussions with NASA. During these discussions, a stainless steel model was considered. Please clarify the material for the 10” Venturi meter.

ANSWER: Confirm, use Fiberglass Reinforced Plastic (FRP) for the 10" Venturi as stainless steel is not required.

Specifically, request the following (or equal):

The BIF Model 20182 Fiberglass ReinforcedPlastic (FRP) insert Universal Venturi Tube (UVT®)


QUESTION: GFE skids and components require a final cleaning. However, because some skid valves are actuated, please identify who will be responsible for the control system to activate the valves necessary to perform this final cleaning.

ANSWER: The install contractor shall be responsible for actuating the valves as needed. There is an option to remove valve plugs and other components with NASA approval.

QUESTION: Upon receipt of GFE VJ piping and skids, the contractor will be responsible to monitor and record the vacuum levels of each VJ assembly. Please advise if the VJ spools/assemblies vacuum trending records compiled while in the government’s procession will be provided as part of the data packages to the contractor.

ANSWER: Yes, the VJ spools/assemblies vacuum trending records compiled while in the government’s procession will be provided as part of the data packages to the contractor.

60. REFERENCE: Drawing K0000079480 and Specification K0000231317-SPC, Section 40 60 00, paragraph 3.1 under systems tests.

QUESTION: The language given in the referenced specification alludes the cryogenic vacuum jacketed piping cold shock is to be done before installation of the field joint cans. The historical intent of a cold shock is to subject the installed system to near operational stresses due to thermal movement and delta temperatures. If the VJ cans are not installed during cold shock the inner lines will be subject to all of the loads (especially at the field joints) and little will be transferred to the supported outer jackets which is not a simulation of operational conditions and may compromise the hardware. Recommend that the system VJ cans be fully installed and vacuum established before cold shock.

ANSWER: NASA has directed that the cold shock shall be done prior to the installation of the cans so that the field joint welds can be inspected after the cold shock. The cold shock shall be performed prior to the can installation as specified in K0000231317-SPC, Section 40 60 00.

Holes shall not be drilled in the pipe spool vacuum jacket until after the cold shock has been performed, and the holes shall be drilled just prior to the field can installation and close out.
