Questions and Answers

Number Spec Section Question Answer

1 07 22 00

Section 07 22 00, page 5, section 2.3.1 states “high density wood fiber” however, on page 6, section 3.2.2.1, the heading is “polyisocyanurate insulation” which is not the same as wood fiber and in the paragraph directly below it states “1/2” wood fiberboard, glass mat gypsum roof board…”

Paragraph 2.3.1. should be changed to read as follows: Provide 1/2" gypsum fiber roof board in accordance with ASTM C1278.

Remove reference to "wood fiberbaord in Paragraph 3.2.2.1.

1.a.

Can you please clarify what type of cover board is being requested as three different types of cover boards are listed here? (If it helps, you will get the best results out of a ½” Gypsum Fiber Roof Board ASTM C1278) -Section 07 54 19, page 8, section 2.1.1 states “minimum polymer thickness .060” and color to be “Décor Tan”. -Section 07 54 19, page 9, section 2.1.4 states “minimum polymer thickness .072”.

-Section 07 54 19, page 10, section 2.2 states “Fleece Backed .072 minimum” and directly below under item A it lists 60 mils thick Fleece Backed PVC

The design intent is to have a 60 mil PVC roof membrane with a fleece backing; for a total thickness of 72 mil minimum.

1.b.

Can you clarify what membrane is being specified? .060 or .072, minimum thickness or nominal thickness and Fleece Back or bare backed membrane?

The design intent is to have a 60 mil PVC roof membrane with a fleece backing; for a total thickness of 72 mil minimum.

1.c.

Regarding the color of “Décor Tan”; Décor is typically the name associated with the Sarnafil Décor Rib systems (simulating standing seam metal). Does this project contain any sections requiring this type of “rib” system?

No, the décor tan is the type of color to be used for the thermoplastic layer on the flat roof only. The standing seam roofs are a different color.

Questions and Answers

Is there any other specific information to be presented with the proposed schedule rather than tasks, starts & finish dates?

No, the items listed within the specificaitons regarding schedules is all that is required.

Is there a power source available at the building during construction phase for use by contractor/subcontractors?

Yes, the contractor can use the existing power coming into the building.

8.a.

My question is, I see no mention in the design, of the building gas and electric metering. Should I assume that the existing meters will remain and we will tie them into the new system?

PD102 shows removal of the gas meter and gas service. ED106 shows the locaiton of the existing electric meter that is to remain.

The controls for the elctric meter should remain and be integrated on the new system.

8.b. Do new meters need to be furnished and installed?

No. The gas meter is being permanently removed and the electric meter and water meter are to remain.

Are there existing Fire Sprinkler system as-builts available and released prior to bid?

Yes, reference Attachment titled Bldg. 5008 Fire Protection Plan (1 sheet) and Attachment titled Bldg. 5008 Fire Sprinkler System Piping Plan (1 sheet) (These attachments are posted with the Q&As on FBO)

Other than the SAFB Fire Marshal, are we required to submit to any other AHJ (i.e. Leidos or Corps of Engineers?)

No, the 126th CES and SAFB Fire Marshall are the only approving officials for fire protection. The Architect/Engineer Fire Protection Design Engineer will be reviewing the construction as well and providing input to 126CES.

Are we allowed to leave the fire sprinkler system out of service during the duration of construction?

Yes, however it needs to be coordinated with the 375th Base Fire Marshall.

Will this project be broken up in Phases or estimated flow working from N-S, E-W?

Room 120, and Toilet 122.

Project Number: VDYD132014 Current a/o 15 Jun (1520hrs)

Questions and Answers

Are we additionally required to utilize the UFC-3-600-01 (Ver.

11/28/2016) along with NFPA 13 standards for redesign? Yes

Please confirm that this is a "Buy American"/domestic material only project.

All applicable Federal Acquisition Regulation (FAR) clauses and requirements regarding the Buy American Act are listed within the Solicitation.

Other than shown; is the intent of the FP SOW to reuse the existing sprinkler head outlets as much as possible for redesign and leave all existing branchlines, mains, riser assembly & backflow to remain unchanged/as-is?

It is the intent to utilize the existing piping to the extent possible, however, as indicated in the drawings, many of the branches and heads need to be modified to fit the new floor plan and ceiling grid.

The riser assembly and backflow preventer are expected to remain unchanged/as-is.

Are we required to recalculate the existing system for the new floor layouts/renovations?

Yes. In accordance with specification 21 1313.00 10, paragraph 1.2, the contractor is responsible for design of the sprinkler layout including hydraulic calculations.

Are there an HIGH security areas that have lead lined walls/ceiling that require special pipe penetrations (i.e. transition to CPVC or other special fittings) No, there are no lead-lined walls.

Making the bid due at 1 PM on Monday essentially means all sub bids will have to be received by Friday in order to prepare the bid and transport to Peoria by 1 PM. Equipment suppliers are notorious for holding their bids until the last minute for fear of having their numbers shopped. Even if we direct our subs to submit on Friday, the majority of mechanical and electrical numbers won’t come in until Monday morning, delaying preparation of the proposals and forcing contractors to choose between quality and expedience to deliver the proposals. If the bid turn-in time was changed to 4 PM, this would allow time for bids to be received on Monday morning and proposals finalized properly to ensure best value pending

Project Number: VDYD132014 Current a/o 15 Jun (1520hrs)

Questions and Answers

This project will be bid by a large number of local contractors with bids provided by local suppliers. Making delivery of the proposals to Peoria @ 1 PM creates a hardship for these contractors to prepare and submit their best value proposals. This process will reward the contractors who can afford the additional manpower and cost to have proposals. If the bids could be delivered to Scott AFB, it would provide additional time to ensure the small businesses bidding this project have the additional time to receive quotes and ensure best value is presented. The proposal due date location remains the same.

The framing details are unclear on existing framing. Seeing the original design drawings would assist in takeoff and construction of the new framing. Are the structural and architectural as-builts available for the building? pending

Plan Sections 5/6/S503, Section 3/4/S504 and Details 1/2/3/A702

Areas of Concern: The brick wall between the windows is less than 2 foot. After we remove existing jacks from both sides of window's there will not be anything holding the existing brick or stone column in place, all the brick ties will be disconnected. If the brick lintel above the windows that holds up the upper band of brick is loose and setting on masonry that is a lot of weight on a unsecure column . There is not a good way to re-connect the brick or stone back to the new stud work .

Also the gyp sheathing will be in pieces and there will be no continuous vaper barrier. pending
