Item Question Response

1 Do the Superintendent, SSHO and QC Manager need to be 3 separate individuals?

The Superintendent can also act as the Safety Specialist. However, the Superintendent cannot act as the Quality Control Specialist. The Quality Control Specialist and Safety Specialist can be the same person.

2 Are there any phasing requirements? No, Contractor is resposible to develop project schedule.

3 If the building remains occupied, how many people will be in the building? Building is not occupied.

4 Are there any temporary heating/cooling requirements? Contractor is responsible to maintain

Can the period of performance be extended after award once the material/equipment lead times are confirmed due to current market conditions for the equipment for this project?

This can be considered.

Are soil boring reports available? If not, it will be assumed that excavation will be clear of rocks and obstructions.

See specification 01 11 00.

7 Please provide bidding quantities for deteriorated underlayment (roofing)/base course (paving).

Contractor to determine quantities based on the construction documents and the Site Condition Survey Report.

Please confirm the manufacturer of the existing roofing system and who carries the current warranty of the roofing system.

The roof membrane that is currently on the roof is a Johns Manville TPO membrane. The AE does not believe there is a warranty for the current roof system.

Please confirm whether asbestos or lead is present on this project, and if so, provide the relevant documentation.

NPS's understanding is that there is no asbestos or lead present on this project. However, we are not able to provide documentation.

10 Please provide the contact information for the building controls contractor. There is no building controls Contractor 11 Please provide the contact information for the building fire alarm company. Vector Security, 171 West Dunbar Cave Rd, Clarksville, TN 37040 12 Please provide the site visit attendee sign-in sheet.

In the Women's bathroom (002) sheet A7.1 of the drawings does not include the elevation detail for the entry door wall. Which, if any, wall tile will be going on this wall?

Tile W-3 shall be installed on that wall up to 5'-0" AFF (similar to details 3 & 5/A7.1).

In all of the bathrooms, the finish schedule calls for matching the tile base to the wall tile, is this correct even though each bathroom having two different types of wall tile?

The wall base tile shall be a 4x4 cove base tile that matches Tile W-3 for all the walls in each restroom/bathroom.

17 What should be used for the top of each wall tile to cap the tile? A bullnosed, finished edge.

Certain products and colors that are specified for this job have been discontinued and are no longer available, should we be getting as close to the requested color as possible, or is there an updated spec sheet?

Our recommendation is to replace the discontinued American Olean A81-Summer Rain with American Olean 0A36-Discovery and the discontinued American Olean 0045-Salt and Pepper with 4x4 Daltile ColorMatch Glazed Ceramic Tile CU33-Matte Carrara.

"The contract drawings and specifications list “Louvers, frames, and accessories” (Section 08 91 00), but several openings appear to include previously installed louvers, and at least one (A3.2) corresponds to a mechanical outside-air intake (“20 × 20 OA Intake” per M1.1). Please confirm:

A) Whether all exterior louvers under Section 08 91 00 are to be replaced in full or reused if existing units are serviceable.

The AE is not aware of any exterior louvers other than the one shown on A3.2, under the ramp. It was shown as 20"x20" on the construction documents, however, it was revised to 30"x20" in the submittal review and that is what was installed. The Site Conditions Survey Report states that this louver shall be replaced with a new aluminum louver. The louver shall be 30"x20" to match the opening. It shall have the appropriate trim flange to cover the gaps at the perimeter, and meet specification section 08 91 00 - Louvers.

B) If replacement is required, confirm model, performance criteria (AMCA 511, AAMA 2605 finish), and finish color (Benjamin Moore AC-29).

See specification section 08 91 00 - Louvers for requirements.

C) Confirm that the 20 × 20 fixed metal louver on A3.2 / A8.3 serves the mechanical OA intake, and that the architectural trade (Div 08) is responsible for furnishing and installing the louver assembly (frame, blades, finish, sealant), coordinated with Division 23 for ductwork termination, damper, and airflow testing."

As stated above, the louver is a fixed 30"x20" metal (aluminum) louver. The louver is specified in specification section 08 91 00 - Louvers. The General Contractor shall decide who furnishes and installs the louver.

20 "The Site Condition Survey indicates elevator installation is incomplete.

Elevator is stored in Thyssenkrup Elevators facility in Piperton, Tennessee. Contractor should coordinate elevator installation with Thyssenkrup. Jonathan Hord, Construction Superintendent M: 1-615-405-1629 jonathan.hord@tkelevator.com

Please confirm whether scope includes furnishing a new complete elevator system or completing work on existing equipment.

Elevator is stored in Thyssenkrup Elevators facility in Piperton, Tennessee. Contractor should coordinate elevator installation with Thyssenkrup. Jonathan Hord, Construction Superintendent M: 1-615-405-1629 jonathan.hord@tkelevator.com Additional AE Comments:

Per the original construction documents, the contractor must also coordinate elevator sprinkler and fire alarm requirements with the AE. The elevator is a machine-room-less hydraulic elevator.

Since the pump and hydraulic tank are located in the elevator pit, the pit is the machine room.

The fire sprinkler must be installed above the height of the tank; a heat detector is required to be installed within 24 inches of the sprinkler; and the luminaires in the pit must provide a minimum illumination level of 19 footcandles measured at the floor of the pit. The elevator controller will be located in the door jamb of the elevator. Coordinate the location of fire alarm control relays with the location of the controller. A minimum illumination level of 19 footcandles is also required at the location of the controller.

22 Provide manufacturer basis-of-design and warranty requirements."
