QUESTIONS:

Question # Question Answer/Response

1. Were any core samples taken of the existing roofing at this project? If so, can NPS provide the results? If not, can we examine the roof to determine existing conditions?

Contractors need to be aware that core sample is for demolition purposes only. The contractor needs to add insulation to meet New Building Codes requirements R30.

See Section 07 53 23 12.4.

BLDG 108 core sample consists of -Metal deck -1” fiberglass -Built up roof -1/2” saturated

-EPDM

2. Are all 4 Sides of 108 & INDU 1&2 having a knee wall being built? If so how will the water drain off of the roof?

All the existing knee walls will be fill with insulation and drain to the existing gutters. The contractor will install additional insulation to meet R30 to the entire roof and keep existing drainage, including replacing the existing gutters.

3. Will scuppers be used at lower edge of roof? Please ensure that scuppers are not used for any of the buildings. All roofs should slope towards the existing gutters, which will be replaced as part of this project. The contractor must adjust the elevation of the gutters to accommodate the new height, depending on the new insulation.

4. What will the knee wall be constructed out of?

2"x4", "2x6", "2x8", "2x"10?

Use 2x6 if necessary, the contractor shall match existing roof knee wall.
