1. What is the contract duration for this project inclusive of phases 1, 2, 3A, 3B, and 4 per drawing G-003 Phasing Plan? 515 calendar days. 90 for submittals, 60 asbestos abatement and 365 for construction Can any of the phases be completed concurrently or is it required to be sequential with completion of Phase 1 required before beginning Phase 2, 2 before 3A, 3A before 3B, 3B before 4? No, contractor is required to work the phases as planned. VA needs to maintain the required minimum beds on the floor. Upon contractor completion of an individual phase and government acceptance of that Phase for beneficial occupancy, the government shall release the next Phase to the contractor. Contractor shall not start a Phase until directed to do so by the government. The VA has determined that each Phase is critical and requires beneficial occupancy prior to contractor starting the next phase. Accordingly, it is a requirement that each Phase be completed and approved for beneficial occupancy by the government prior to contractor beginning the next phase. VA will provide approval of a Phase or provide notice of its non-approval within 10 business days. The VA will provide direction to move onto the next day within 4 business days of its approval of a phase.

See Revised G-003 Drawing with Bed Count summary.

1. Who is the existing fire alarm manufacturer? Edwards is MFG, Red Hawk service.

1. Who is the existing nurse call manufacturer? Westcall.

1. I have a question on drawing M-001 under Project General Notes, see attached, it states the Mechanical Contractor shall perform service and repair on the existing equipment. Is there a list of the equipment that needs repair or service? There are no repairs or service on equipment other than what is specifically called out for on the drawings and specifications.

1. On the demolition drawings it shows removing duct branch lines back to the mains and the HWS&R and CHS&R branch lines back to the mains. Does the insulation on the mains, duct and piping, get removed and replaced or does it just get repaired? In general, the mains do not get re-insulated. All new connection points coming off of existing mains do get repaired and insulated at the connection point.

1. Please provide room location and total count for the new lift, as well as the locations for the pre-existing lift systems. While Drawings S-200 & S-108 show the lifts, the first drawing says see Arch drawings for locations, yet also points to L1 as the lifts. Need to understand whether L1 in this sheet refer to the new lift systems and not pre-existing ones. Contractors are required to review Contract Drawings to determine the required number of new patient lifts. Note L1 on S-108 does reference the rooms that are to receive new lifts. Architectural reflected ceiling plans (A-308A, A-308B, A-308C) can also be referenced when looking at General Keynotes 01 and 02 on those pages to determine which rooms have reinstallation of salvaged patient lifts and which ones receive new ceiling mounted patient lifts.

1. Alternate #1 states the scope of work for certain rooms involves only mechanical work. I cannot find room A823 and how does this alternate pertain to the door/frames & hardware? Note: A823 is mentioned three times in the drawing set (See 1/A402 & E-701). Is A823 another name for the MECH 1 space labeled MS1 that is connected to the A822 Equipment room or is there another explanation? A823 is reference to an additional patient room that used to be in the plan before the Equipment A822 was added. Patient room A823 is no longer in the plans. Regarding the alternate that A823 was mentioned in, the intent of the alternate is to upgrade only the HVAC systems in patient rooms where the existing walls are to remain. This can also be determined by which rooms are denoted to have salvaged patient lifts to be reinstalled (A819, A826, A828, A835, A837, A841, A847, A846, A842, C842, C839, C837, C831, C827, C804, C807, C809). The room numbers provided here should be referenced for this alternate in-lieu of the original numbers provided.

1. Some of the documents make mention of STC rated walls and/or STC rated doors & frames. The door schedule on plan page A-601 does not appear to designate any units to have STC ratings?

1. Can equal hardware products be substituted for all of the Sargent brand items listed in the hardware sets?

All substitutes have to meet the drawings and specifications 100%. Contractor will be required absorb any issues or costs associated to hardware that does not fit.

1. Opening B814.1 calls for it to be LC/GS which by the elevation shows an Access Panel, but it calls for the size to 2’0” x 7’0” x 2” Thick. Is that correct? No. 2’0” x 7’0” x 1 3/4”. Per the designations and the elevations on A-601 that door is a 90 minute rated steel door for the laundry chute. It is small in size, but it is to be a swing door similar to what is utilized throughout the building for the laundry chute. It is not an access panel.
