B. Building(s) Name/Identifier: See TABLE NO. 1.

C. Work consists of the following:

1. Full tear-off of roof system at areas indicated on Drawings or in Photographs provided.

a. Removal of existing roofing system down to existing roof deck.

2. Re-cover preparation of entire roof area where tear-off occurs, including installation of new roofing system.

3. Removal of flashings and counter flashings.

4. See table No. 1 for more details.

5. Removal and replacement of gutters and downspouts.

6. Removal and replacement of plumbing vents and boots in kind.

7. Temporary roofing during construction where required. Temporary roofing shall maintain the project roof is watertight and able to prevent leaks and damage to the building and structure until the reroofing work is completed. Contractor is to make sure that at the completion of work each day the projects roof is 100% watertight.

8. Remove and replace the existing roof membranes and associated roof flashings, the existing rigid roof insulations down to deck and patch any openings in the structural decking as required before installing the new ridged roof insulation, roof insulation crickets, expansion joints, all associated roof flashings, counter flashings, and metal copings. Provide new roof drains.

9. National Park Service (NPS) requires the existing roof decks to be walked after demolition has been completed with their onsite Contracting Office Representative (COR) or designated Project Inspector prior to installation of any new roof materials to ascertain if any water penetration has caused deterioration and corrosion of the existing decks which are to remain. If there are areas of concern the COR may require the Contractor to perform pull out tests to determine if the existing decking in question can remain or if it will need to be replaced. This can include visible areas of water damage or insect related damage, and concrete decks for spalling and other visible damage. Testing and replacement of these types of unforeseen damaged areas will be by Change Order if required.

D. Roof Area:
