Materials due to the age of the piping.

Question 16: Reference Attachment D, SSC Task Order, SSC J-2 Drawing C 101. Can elevations be provided for high and low water within the lock and for the adjacent work areas?

Answer 16: High pool water elevation within the lock is roughly 18 feet above mean sea level

(MSL). Low pool water elevation varies based on river stage and tidal influence, but can be roughly approximated to even with MSL +/- 2 feet. Groundwater within the area around the lock is subject to constant recharge due to the adjacent canal. Seasonal variations will determine groundwater level, but groundwater elevation should be assumed to be at ground surface until proven otherwise for all design and construction purposes.

Question 17: Reference Attachment A (JSC) we have not been able to find Geotech reports within the RFP packages for the referenced project. Excavation work at Johnson Space Center requires the review of existing soil and groundwater conditions. How can we obtain these reports?

Structures, makes no mention of painting whatsoever and we are unable to find any information about painting of the piping, valves and miscellaneous steel supports in the drawings. Please provide information on the types of paint systems to be utilized for the work in this contract.

Answer 18: Painting of Piping and Components Coating: Carbon steel piping, pipe fittings, pipe spools and appurtenances that are not galvanized shall receive one shop coat of inorganic zinc primer (Carbon Zinc 11 or equal). Painting shall be performed after completion and acceptance of all welds to the maximum extent possible. Where field welds are required to enable transport of pipe spools to the job site and where use of mechanical pipe connections are not feasible, the pipe and fitting material shall be left unpainted within 6-inches of the field weld end preparations. Final painting with Carbon Zinc 11 or equal primer at field weldments and with full application of intermediate and top coats shall be performed in the field after erection of piping systems and completion of all welds. Surface preparation prior to painting and painting application processes shall conform to manufacturer specifications and recommendations.

Structural Steel and Miscellaneous Steel Coating:

Steel shall be hot dipped galvanized per ASTM A123/A123M or ASTM A153/A153M, as applicable. All damaged galvanized surfaces shall be repaired by applying an organic zinc repair paint complying with the requirements of ASTM A780/A780M. Galvanizing repair paint shall contain 95 percent zinc by weight. Thickness of applied galvanizing repair paint shall be no less than the coating thickness required by ASTM A123/A123M or ASTM A153/A153M as applicable. Contractor shall use ZRC cold galvanizing compound or approved equal for repairs.

Question 19: Reference Attachment C, MSFC Task Order Drawings Sheet M402, 2/M402

AH0035 indicates three supply ducts down to first floor – see sheet M112 for continuation. Sheet

M112 does not indicate the third supply duct. Please verify accuracy of Sheet M112.

Answer 19: The third duct is shown on sheet M111, as the sheet division between M111 and

M112 occurs in between the duct drops. Detail 2/M402 was revised to correctly call out the location reference for the third duct.

Question 20: Reference Attachment C, MSFC Task Order, Sheet M111, 1/M111 lower right corner indicates an exhaust duct (duct size – 24x18, 26x24 and 30x30) but does not continue on

Sheet M112. Please advise if continuation of this duct is missing on M112 and if so, what AH

Unit this goes to?

Answer 20: The sheet matchline cut on sheet M111 is too short, the drawing was amended to show the full length of the ductwork.

Question 21: Reference Attachment C, MSFC Task Order Drawing, Sheet M402, 2/M402 existing AH0035 indicates three (3) supply ducts down to first floor (see M112 for continuation) but M112 does not reflect this duct at Grid 8. Please advise as to this supply duct location on

M112?

Answer 22: The third duct is shown on sheet M111, as the sheet division between M111 and

Question 23: Reference Attachment C, MSFC Task Order Drawing, Sheet M402, 1/M402 titled

“E-9, Room 228 to read E-8, Room 228?

Answer 23: Correct, Room 228 should be E-8, the drawing was amended to show the correction.

Question 24: Reference Attachment C, MSFC Task Order Drawing, Sheet M212, 1/M212 indicates air supply / air return penetrations left of Gridline 13. Sheet M404, 3/M404 show this supply / return for AH0031 to be right of Gridline 13. Please advise as to the correctness of drawings?

Answer 24: The discrepancy comes due to a misalignment of the equipment room in respect to the column line between floors in the cad files. The location of the duct on either side of the column line is of no consequence to the design, since the space is open below. Install air handling unit in the room as shown on M404, and the ductwork will penetrate the floor as required as space dictates.

Question 25: Reference Attachment C, MSFC Task Order. Are we to provide new 4” housekeeping pads at all new AH units?

Answer 25: Reference detail 3/M503. All air handlers will require new 6” housekeeping pads, 6” larger than unit in each direction, unless condensate trap height dictates taller pad. Sheet

M503 was amended for this requirement.

Containing Materials. We do not have this section included in the specifications for the sanitary sewer work at JSC. There is a Section 02 82 14.00 10 – Asbestos Hazard Control Activities. We surmise this section is included in case the contractor encounters asbestos containing materials and that this work would be considered to be a change order since Section 01 22 00.00 80 –

Special Requirements, paragraph 1.26.2 says …”There are no asbestos containing materials expected to be in the work area.” We also do not find any reports of asbestos containing materials in the bidding documents for JSC. Please confirm the above and the intent of this asbestos abatement and removal section.

Answer 72: Specification Section 01 22 00.00 80, Paragraph 1.26.2 incorrectly states that no asbestos containing materials will be encountered on this project. The asbestos pipe in the work areas is identified as “Existing Concrete Pipe”. The contractor is responsible for identifying the work location and quantities associated with all aspects of this project. A change order will not be allowed for this asbestos work. Specification Section 01 22 00.00 80 has been edited to delete that statement. Specification Section 01 30 00 is not applicable to this project and has been deleted in its entirety. Specification Section 01 41 00.00 80 with its reference to the JSC Safety and Health Handbook (JPR 1700.1) is the applicable Section for the asbestos abatement requirements. Section 02 82 14.00 10 has been deleted in its entirety.

Question 73: Reference Attachment A, JSC Task Order Drawings. With respect to question above, General Construction Note 15 on drawing C4 says …”The existing asbestos concrete main will need to be breached in several locations to cap or plug the pipe or to tie the new line to the existing line.” We are unable to find such a connection in the drawings. Please clarify where this situation occurs.

Answer 73: The asbestos pipe in the work areas is identified as “Existing Concrete Pipe”. The contractor is responsible for identifying the work location and quantities associated with all aspects of this project.

Question 74: Reference Attachment A, JSC Task Order Specification, Section 01 45 04.00 80 –

Contractor’s Quality Control, paragraph 1.4.1.2, Quality Control Staff, indicates that specialized

CQC personnel shall be provided for electrical, mechanical, civil, structural, survey control, and environmental. Since this project does not include any buildings or structures, lift stations or pumping facilities, power transmission or controls systems, we question the need for the specialized CQC personnel for electrical, mechanical or structural. Please review and clarify these requirements.

Answer 74: The contractor shall provide the personnel necessary to ensure that the work being performed under this project is in compliance with the contract. Specification Section 01 45

04.00 80, Paragraph 1.4.1.2 refers to numerous disciplines since it is not the government’s intent to limit the contractor’s expertise at the job site. The contractor is responsible for providing the proper individual(s) with the proper expertise.
