5 Can we use non-treated lumber which is acceptable by the manufacturer? Yes

6 Building 334 EPDM spec’d is .090 reinforced.

Is this correct?

The specification should have read 60 mil reinforced membrane

7 Can we use aluminum for all the coping and fascia? If so what gauge? .050 aluminum see #4

What are we to do with the concrete pavers holding the existing membrane on 5-3 down?

The contractor will remove the pavers from the roof, stack them on pallets and place them on the ground. The Government will remove them from the jobsite. If needed, the Government will supply pallets to hold the pavers.

9 Can the existing coping be shop formed from mil finished as per one existing parapet cap? No

10 Is the entire coping, fascia, gutter to be dark bronze? Yes

There is no mention of the insulation or ecostorm coverboard in the spec, it is called for in the SOW but the spec doesn’t have any provision for it.

Both roofs will have the Ecostorm coverboard installed in the system due to it's high recycled content.

12 Is the wind rating 110mph correct? All roofs at TYAD from the past had a 72mph rating

The wind rating for the roofs will be 72mph.

Disregard the 110mph rating.

Please clarify that the metal copings are to be bought through Carlisle and included in the warranty with all ES1/FM certifications

All metal products must be compatible and covered under the roof manufacturers warranty.

In light of the material shortages - specifically Polyiso insulation. Would TYAD consider switching to an alternative insulation (in place of Polyiso) that is more readily available as long as the following criteria are met:

The material may be substituted if it meets these requirements. 1) Adjust thickness to meet the R value in the solicitation. 2) No change to external & internal fire Rating. 3) Density similar to Polyiso

4) Must be warranted by the roof manufacturer as part of the roof system warranty.

how are we fastening the new insulation on building 5?

The insulation board will be mechanically fastened as per manufacturers recommendations to attain a full system warranty

16 is there steel decking below the gypsum that we can fasten into?

No

As per roof plan drawing building bay 3 general note says to remove and replace existing roof system.

1) Are we removing the roof system down to the gypsum substrate?

2) Or only the EPDM membrane to then inspect and if found wet remove current insulation.

We are removing the EPDM leaving the existing insulation. Inspecting and replacing with dry insulation if wet.

Please also clarify SOW Page paragraph 1.4.1 are we installing R30 minimum over existing insulation.

Install new insulation over the existing insulation to total R30. If the existing insulation is R15, contractor will add an additional R15
