| 7/10/20 | ||
| 6 | I have a question regarding the HVAC specs and drawings for Chilled Water piping materials. The drawing M501 #3.4 says the chilled water piping about 6” can only be welded joints. But the spec 23 21 13 says the chilled water piping 2” and above can either be welded or grooved. Which of these is correct? | Chilled water piping 6" and above, shall be welded only. |
| 7 | Spec 23 07 11, Part 1.1, Paragraph A, Item 2 calls for reinsulation of HVAC piping, duct, etc. after abatement of asbestos. There are no pipe abatement specs given. Also, there is no pipe, equipment or duct insulation asbestos abatement scope shown on the drawings. Please clarify what the spec refers to. If there is insulation asbestos abatement please provide a clear scope and quantities. | There was no asbestos pipe and/or equipment insulation referenced in our report. Therefore, there shouldn’t be any planned abatement of pipe and/or equipment insulation at this time. |
| 8 | Insulation specs 230711-1 specifically call for re-insulation after Asbestos abatement. No drawings indicate removal of insulation due to asbestos abatement. Please confirm that this does not apply. | There was no asbestos pipe and/or equipment insulation referenced in my report. Therefore, there shouldn’t be any planned abatement of pipe and/or equipment insulation at this time. |
| 9 | Specifications are not clear on whether jacketing is used on Chiller plant indoors. Was there Aluminum or PVC Jacketing on piping to be demolished? | Provide color coated PVC jacketing per ASME A13.1 for chilled water piping. No known Aluminum or PVC Jacketing on piping to be demolished. |

Intent is not to abate areas of lead paint. All work requiring grinding, cutting, etc., to be performed in a safe manner per the contractor’s means and methods and the guidelines set forth by the Occupational Safety and Health Administration for lead: • Step 1: Determine if the Job Involves Lead-Based Paint. • Step 2: Set It Up Safely. • Step 3: Protect Yourself. • Step 4: Minimize the Dust. • Step 5: Leave the Work Area Clean. • Step 6: Control the Waste. • Step 7: Verify Work Completion with the Cleaning. | |
| 13 | Drawing S-001 calls for structural steel inspection, then continues to specify visual inspection of all welds, 10% of primary connection fillet welds get mag particle, and 100% get UT. There are different and more stringent specs called out in 01 45 29 for testing requirements. Which will be used to govern testing of concrete and steel? | More stringent requirements between dwgs and specs shall be followed. | |
| 14 | If steel is to be UT inspected, should it be inspected before galvanization and at the shop? Field UT of galvanized steel is not recommended. | Shop or field UT testing is acceptable. | |
| 15 | Spec section 23 05 11 uses the terms “Coordination/Shop Drawings”, but our understand of these two are very different. We interpret Coordination Drawings as those BIM or CAD drawings issued to ensure no interference/clashes between systems, whereas Shop Drawings are from the OEM. Please advise which drawings the VA is expecting. | Coordination drawings are submittal drawings (CAD or BIM) to be reviewed to assure disciplines have been coordinated and maintenance/access has been shown. Shop drawings (i.e. fabrication, erection drawings) are submittal drawings (CAD or BIM) to be reviewed to assure construction standards are being met. Both are required per the specs. | |

Please confirm. | As noted on SD103, all ex steel dunnage framing & bracing and existing pipe dunnage posts shall be selectively demolished. Existing steel wide flange dunnage post/column shall remain. | |
| 20 | Who is the existing roof contractor providing warranty on roof? | Firestone | |
| 21 | Please confirm only steel fabricators holding AISC certifications are approved for steel supply on this project. | Refer to specification section 051200-1.4 for required steel fabricators and installers qualifications/certifications. | |

| 7/14/20 | |||
| 50 | The mechanical details do not show a triple duty valve on the pump discharge, but the hydronic piping specs call for one at 23 21 13, 2.1, G,1. Please clarify. From experience, these are several thousand dollars and there are nine of them. All nine will cost several tens of thousands of dollars. | Triple duty valves not required or recommended. | |

| 52 | Reference: Contract Specification Section 02 82 13.21 Roof Asbestos Abatement (Note: Documents Contain two such sections the first is 4 pages long). Subject: Extent of Contractor Responsibilities Not Clear – Asbestos Abatement Monitoring, Testing & Inspection. Question: The specifications for the Roof Asbestos Abatement are confusing regarding the extent professional monitoring, testing and inspection required of the bidder as the specification seems to imply that the owner and the contractor are required to perform similar services (refer to sect 02 82 13.21 para 2.3 and elsewhere). Please clarify. | The contractor has a responsibility to monitor his own employees’ exposure to hazardous materials under 29 CFR 1910.120.

Question: The Contract Drawings note that “Existing Building has the presence of Lead Paint. Refer to the Specifications.” Since the specification’s do not delineate the location or quantities of lead paint, the scope of this work is undefined. Please Clarify. | See response to #12. | |
| 54 | Reference: Contract Drawings SD102, SD 103 and S 50. Subject: Existing Roofing System Undefined. Question: The Contract Drawings note that Contractor required patch, flash and seal the existing roofing where openings are closed or penetrations patched to “match the existing roofing material”, which is noted as a Firestone product. Please advise the existing type of Firestone roofing system, i.e. BUR, SBS, EPDM or PVC and approximate year installed. | Notes on SD102 (#7), SD103 (#5), SF-102 (#7), and SF-103 (#11) require the contractor to coordinate with the COR and Firestone’s instructions and details “so as not to void any warranty”. In addition, Detail #2 on S-502 also states for the contractor to “match existing”. | |
