3. The special warrant stated in section 076200 paragraph 1.10 for a 60 year manufacturer¿s warranty is problematic. We checked with our vender/manufacturer for sheet lead and no such warranty is offered, nor will they offer such a warranty. From an GC and installer¿s perspective, our surety will not bond a project with such warranty requirements. Will NPS remove this warranty requirement given it can¿t be offered by the manufacturer?

Specification Section 076200 - 1.10.A.2 will be changed from a 60 year warranty period to 20 year warranty period.

4. Detail 6/A3.0 is not clear on how the cleat will attach to the coping stone? Is this attachment to be designed by the installer? Or does NPS have a preference on how to attach the cleat.

No mechanical fastening into the stone is permitted for flashings or attachments. Details illustrate design intent. Per Detail 6/A3.0, cleats shall not be attached directly to the coping stones, but are to be tack welded to the metal armature provided by the Contractor. The armature shall span each coping stone and shall be secured to the coping stones by insetting each end within the stone joints using fixing clips with sealant (see Detail 4/A3.0). Armature shall be custom fabricated based on the radius and lengths of the coping stones to be verified in field. Shop drawings and mock-ups are required to be completed by the Contractor for approval following inspection of existing conditions.

5. Detail 2/A3.0 does not show a cleat or clip anchor detail for the back edge/hem of the lead panel intersection with the roof apron flashing.

Is this attachment to be designed by the installer? Or does NPS have a preference on how to secure the panel to the substrate?

No mechanical fastening into the stone is permitted for flashings or attachments. Details illustrate design intent. Cleats and clips are not to be used at the back edge of the coping flashing where it intersects the existing roof flashing. Per Detail 2/A3.0, a non-moving flat-lock seam with sealant shall be used to secure this edge of the coping flashing to the existing flashing to remain. Photos of the
