RFI: Vendor Questions for CRFQ DNR27*02 Blennerhassett Island Mansion Roof Rehab

Q1. RE: Drawing A-100 Roof Replacement Note 12

At the pre-bid meeting, it was established that one of the dependency chimneys needed to be functional for an annual event. Please clarify chimney cover requirements.

For the non-functional chimneys, is a full cover of the chimney top acceptable or does each individual flue require its own cover?

A. The Chimney at the Kitchen Dependency will be provided with a Hy-Guard “Draft King”SS1313, 3/4” mesh, single flue, stainless steel, chimney cap, with a black powder coat finish. All other chimneys will be unused and the flues will be fitted with un-vented, stainless steel, chimney covers, similar in appearance to the functional cap, with black powder coat finish. The top of unused chimneys will be insulated with 2” rigid insulation immediately below the chimney cover, tightly fitted to each chimney’s existing flue. The fire place of each unused chimney will be closed off with 3/4” plywood, painted black, and provided with a small plastic sign noting as follows:

THIS CHIMNEY IS NOT FUNCTIONAL

DO NOT BURN

Provide shop drawings for chimney cap, chimney covers, fireplace closures, and signage.

Clarifications:

1. The synthetic shake shingle system will be installed using the straight, multi-width installation method.

2. Any cracks in the concrete chimney cap will be sealed with tooled sealant.

3. Step flashing and painted cover board will be provided where the Breezeways attach to the Mansion and Dependencies. See Sketch provided.

4. Reference drawings, by others, are being provided for information purposes only. Chapman Technical Group makes no claim as to their reliability or accuracy.

5. Park Staff can provide transportation services from Belpre Civitan Park to the Island via pontoon boat. A 60’ barge with a 45,000 lb common run weight limit is also available with 24 hour notice required. River transportation requires appropriate weather and river conditions and is generally not available on weekends.
