18. Section 10 14 00 also includes several different sign types that are not project specific and provide no location as to where these signs are to be installed and several signs provide no information as to the amount required for sign. Please provide direction as how we are proceeding. See number 17 above.

19. Detail 10/A600 is calling for a 36”x36” floor access panel rated at 330PSF. Section 08 31 13 does not provide a specification for this item.

Exterior Fire Retardant Treated Wood should be used in the crawl space. FR wood in all other interior locations.

24. Sheet S103 plan notes 1 – 5 are not on the drawing. See attached 405B Renovations Plan Notes S103 with the notes from that sheet with some clarifications by the VA.

25. Plumbing Drawings show the shower as P-601 and P-602. Section 22 40 00 indicates P-601 as a built in shower. Arch drawings the shower as a CT shower constructed in the field. Please what type of showers are correct. Architectural drawings show that the showers are built in.

26. Spec Section 22 40 00 does not have fixture P-602. Please provide Spec. A mistake is made on the plumbing drawing. The ADA shower in room 405B-4A is built-in. P-601 Shower Built-in is intended for all the showers. Use that fixture type for all the showers.

27. Detail 6/A100 provides a floor detail at carpet. Please provide a floor detail for all other floor finishes. Look at 3/A600, 4/A600, and 5/A600. The detail will be the same, just different finishes.

On drawing ES001 under communication cable system design Note 5 states “All cables shall be home runs from each workstation area to the designated communications room” please provide location of the communication room as it is not indicated on the drawings. The nearest Network Closet to 405B would be the one in 403A. Allow approx. 100’ from 405B.

37. Please confirm that the fixture added by Alternate 3 is the H fixture and the drawings are only adding two fixtures. Solar Tubes, fixture H, are REMOVED by Alternate #3.

Please provide direction as to what panel should be utilized or provided a distance that should be included in the bid. Panel 11 in the corridor south before bldg. 407. Approximately 150’ of run. The building is already tied in.

39. Mechanical room 405-3 on sheet ES202 does not indicate any power for DWH-1 which is indicated on the mechanical drawings MH102. Looks like there is power to the electric H.W. heater. May be DWH-1 is mislabeled EWH1.

40. On sheet MH101 Special note 2 calls for an existing radiator to be relocated per drawing MH102. Sheet MH102 provides no location of the relocated heater. Please provide a location. Remove all existing radiators.

41. Sheet PL401 calls for two DWH-1 Solar Domestic and Domestic water heater sheet PL102 only indicates one. Please clarify. Only one H.W. heater. Solar is removed from the project.

43. On Drawing MH 301 Variable Refrigerant Fan Coil Unit Installation detail calls for an auxiliary drain pans under the fcu’s in the crawl space is that correct? Will there be a need for drain piping from them run to somewhere or will the condensate that may happen just evaporate? Drain pans are not needed in the crawl space.

44. The asbestos test report (PDF file page 7 of 18) shows the following note: “*BEC advises that access to the roof was not available during the time of the inspection; therefore BEC was unable to sample any suspect material. As such, BEC advises this material shall be presumed asbestos containing until samples can be collected of the material.” Drawing A150 shows to demo the existing asphalt shingles and replace with a metal roof. Is the contractor expected to carry the cost of removing and disposing of the existing roof as an ACM product or provide testing on the suspected material and address a positive test result with a change order for removal and disposal of the ACM product? Disregard this note about assuming the existing roofing to containing ACM. We have not yet found any asphalt shingles or building paper to contain ACM. Sample can be taken by the VA to remove any doubt.

45. The ICRA document identifies this project as a type C, Group 1, Class 2. This class does not call out for construction barriers according to the documents. If construction barriers are required for this project, can a layout for the barriers be provided? Also, would plastic zip-wall barriers be acceptable? The Contractor can take up to half the corridor east side of 405B for a drywall and stud barrier wall. The door shall be a standard door with a hardware set compatible with our VA standard. See the Hardware specs. The VA locksmith will install the 7 pin core. Any laydown or work area outside the building will need to have a temporary chain link fence that is locked. See specification 01 00 00.

46. There is a specification for signage 10-14-00 (interior and exterior). Can a schedule be provided that identifies types and quantities for bidding purposes? See 17 above.

47. There is a specification for toilet accessories 10-28-00. Can a schedule be provided that identifies types (basis of design) and quantities for bidding purposes? NO. Do the best you can with the drawings and specs. We do not normally list manufacturers.

48. There is a specification for residential appliances 11-31-00. Can a schedule be provided that identifies types (basis of design specifically for oven range, refrigerator, and clothes washer and dryer) and quantities for bidding purposes? The VA will furnish and install all those items when the construction is complete.

49. There is a finish schedule provided on drawing AI100, however the drawings are dated from 2013 with no identification that this schedule was updated with the revision from the VA dated 2019. Can an updated finish schedule be provided to ensure product availability prior to bid? NO. Provide commercial products similar to those specified.

50. Drawing S101 calls for all wood to be fire rated, but the shear wall framing states to use 2 x 6 pressure treated wood 16” O.C. Is the shear wall framing wood to be pressure treated or fire rated as it cannot be both? See 23 above.

51. Drawing A100 Note 6 shows a floor detail @ carpet that looks to be building the floor up from existing subflooring with ¾ APA listed plywood underlayment with sanded face. Then 3/8” then a final layer of ½”. There is no carpet shown on the finish schedule. Is the contractor expected to build up the existing subfloor for other floor finishes on this project? If so, can a detail be provided for this? That detail contains mistakes. Overlay the existing floor sheathing with ¾” plywood. The original finish flooring is ¾’ T&G wood flooring. On the new plywood install ¼” underlayment, then the finish flooring. There should only be a minor transition from the new flooring with finish to the corridor on the west end of the building.

52. Drawing A300 shows an alternate #5, however there is no alternate #5 listed on the drawing. Can you please advise what the intent is on this description? There are only 3 alternates. See the notes on A300.

53. Drawing A600 has a window schedule that identifies the windows to be single hung. Can a basis of design be provided for these windows? Use the Aluminum Window spec.

54. Specification 01-00-00-1.6.I states “I. Construction Fence: 1. Before construction operations begin, Contractor shall provide a chain link construction fence, 2.1m (seven feet) minimum height, around the construction area indicated on the drawings. The drawings do not depict fencing. Is construction fencing required for this project? If so, can a layout be provided? See above references to laydown area and fencing.

55. The drawings only depict work on 405B. When painting on the exterior, does the whole building get painted or only on 405B? Just 405B. In the corridor, just the 405B side.

56. Specification section 01-00-00-1.9.D states “A National Pollutant Discharge Elimination System (NPDES) permit is required for this project. What scope of work on this project requires a NPDES permit as this normally is provided when larger site excavations are performed? Can a project allowance be provided for this item for bidding purposes? If so, what would that amount be for this permit? A storm water management plan and runoff controls will be required for disturbance around the building, but a permit will not be required.

57. The project work area was occupied during the pre-bid walk thru. Will the complete area of 405B be vacated during construction? All of 405B will be unoccupied, and any equipment the VA wishes to retain will be removed by the time the building is turned over to the Contractor.

58. Specification 01-00-00-1.15 states: “A joint 4 month and 9-month warranty inspection will be conducted, measured from time of acceptance, by the Contactor and the Contracting Officer.” Who will be required to participate in these inspections (i.e. subcontractors, vendors, etc.)? Just the Contractor representative(s), COR, CO, possibly a staff member representing the occupant, and any other interested VA staff member (shop, F.D., BioMed, etc.).

59. Specification 01-00-00-1.21 states: “Temporary toilets: Provide where directed, (for use of all Contractor's workmen). Are these required for this project? If so, where would they be placed? Provide temporary toilet(s). See above references to laydown area(s).

60. Specification section 01-00-00-38 states: “Contractor shall transmit each submittal to Architect using the submittal exchange website”. And also states “A particular service may be considered if submitted prior to bid date for pre-approval.” Is Procore an acceptable service platform in lieu of Submittal Exchange? Either one is acceptable.

61. Is it the intent of this project to include new fire protection in the crawl space area? YES. And, in the attic area, as well as below the first-floor finished ceiling. It is a dry system.

62. Drawing G002 Scope of work discusses the alternates as well as the base bid. However, there are 3 base bid items listed that are a little confusing as there are other notes in the structural and plumbing drawings.

1. BASE BID: Remove solar domestic water tank and piping connections. Replace with electric domestic hot water tank. Solar panels and storage tank shall remain for radiant floor heating.

2. BASE BID: Remove solar panels, solar storage tank, solar panels and all associated piping for solar connections to radiant floor. Radiant floor will be heated through electric hot water tank.

3. BASE BID: Remove all pex tubing, manifolds, electric storage tank and all associated equipment for radiant floor system. Replace sheathing and underlayment with plywood as required to maintain finish floor elevation.

Can clarification be provided as to what the base bid includes (i.e., no radiant floor (MH-103), no unsheathed stud wall (9-S101/S501), no solar panels (MH-104), no solar electric water heater (per schedule MH201), etc.? Solar collectors and radiant floors were removed from the design.

63. Note 1. On drawing G001 states ‘Designed in 2013 to codes in effect at that time. Any significant changes to a code should be brought to the attention of the COR and the CO.’ We will strive to discover significant changes to the work due to code changes since 2013, however we are not design professionals and cannot be held responsible to find all code changes that will significantly change the scope of work. Can you please advise on how to proceed? See item 4 above.

64. Drawing S101 shows a stem supporting wall in the crawlspace which is designed to carry the load of the radiant heat storage tank. It is our understanding that that storage tank is removed per Base bid note 3 on drawing G001. Can you please confirm if this understanding is correct? Solar and radiant floor removed. If the tank is removed, so is the support for it.

65. Drawing A300, note states to add standing seam roof over new 5/8” sheathing. Is there more detail to the 5/8” plywood? Is it CDX or Exterior grade. Is it 3 ply or 5 ply? What is commonly used in the industry for rood sheathing with some moisture resistance should be acceptable.

66. Drawing No. AD100 a. General Demotion Notes B & C. Seems as though the end of Note B and beginning of Note C run into each other. Could the VA clarify what both notes are intended to state?

IMMEDIATELY WITH SAME MATERIALS AS ADJACENT CONSTRUCTION. MAINTAIN

REQUIRED FIRE-RATING.

C. FURNISH AND INSTALL FULL HEIGHT TEMPORARY CONSTRUCTION BARRIERS

67. SHEET G001 NOTES: 1. Designed in 2013 to codes in effect at that time. Any significant changes to a code should be brought to the attention of the COR and the CO. The noted commented above eludes the VA has not reviewed all local, state and federal, other VA government codes, VA design documents nor every APPLICABLE PUBLICATIONS listed with-in the specification documentation since 2013. Question: Is it accurate to assume after this deign was vetted by the VA in 2013. See item 4 above.

68. Is Microsoft Project professional format an acceptable scheduling program for CPM schedules. YES.

69. Can the SSHO and the Superintendent be the same person? If they can meet the requirements and have a current OSHA 30-hour training card.

70. The exterior signs list the sign locations by number labels. (Location 1, 5, 7, etc). Is there a site map that lists these locations so that we can hopefully determine what surface the signs are being installed into (concrete base mount, in ground soil, etc)? See item 17 above.

71. Is there a sign schedule for the interior signs so that we know how many of each type of sign will be needed? See item 17 above.

72. SheetAD100 refers to all painted surfaces to be assumed to be lead paint. Drywall, metals and woods. Is this correct the entire demolition would be done under lead abatement procedures? A good idea, but it is up to the Contractor to make representations in their Safety Plan.

73. Can the Superintendent carry QC and SSHO responsibilities? See item 69 above.

74. Will there be a laydown or staging area provided for this project? See references to this above.

75. Will contractor be able to place a dumpster next to the building during construction? See references to this above.

76. Will facilities Industrial Hygienist handle air monitoring and clearing locations after abatement is completed or will contractor need to hire a 3rd party to do monitoring and post testing? The VA will be responsible for collecting any samples they think necessary during construction and the final air tests and inspection. The Contractor is responsible to see that the abatement contractor is complying with OSHA in collection of personal samples.

77. Is there a preferred manufacturer for the windows that are to be installed? NO. Just meet the specs.
