Please price the documents with the assumption that all asbestos containing material (existing flooring and adhesive) will be removed by others (NIC).

A1.2 Is there any lead paint existing in the cabins? Unknown. The existing ceiling is to be painted.

The painted block gets covered by new materials. All demo items have poly/shellac finish.

See General Conditions Article, 11.3 Hazardous Materials.

A1.3 Clarification: All cabins have attic access panels in the ceiling just inside and above the door. Below are pictures of the attic space that are consistent of all ten cabins. Assume existing roof rafters are at 24” O.C.

A1.4 What is the color on the Epoxy Floors? Standard gray, no flakes.

A1.5 What is the width of the Mow Strip? 18” wide

A1.6 Will wood blocking be required between the block and the metal siding @ the outdoor HVAC unit support angle to carry the unit weight? THE SUPPORTS ARE PER THE

MANUFACTURER’S RECEOMMENDATIONS AND ARE TYPICALLY SECURED TO THE STUCTURE.

Assume solid 2x wood blocking installed behind the metal panels to secure Mech equipment supports. GC to coordinate with Mech contractor for size and location of blocking.

A1.7 Pages 1, 5, & 6 are missing from the Specification 054000 – Cold-Formed Metal Framing.

See attached full 054000 Specification. Pages 5 & 6 are intentionally blank.

A1.8 Clarification: Wood Base Trim shall be 2x6.

A1.9 Clarification: Assume existing fascia board (NIC) is in good condition.
