Questions and Answers

Q1. Is there a basis of bid quantity for the roof tile replacement?

A1. Yes. The quantities are noted on the drawing A0 as follows "Assume 20 lf flashing and 50 roof tiles"

Q2. Is mortar analysis required

A2. No but it is acceptable and could limit the number of samples that may need to be submitted for approval to get to an appropriate mix for the mortar

Q3. spec calls for paint/stain removal. Is paint removal part of scope? If so can a SF amount be given for bidding purposes

A3. It states remove paint/stain as a step in the sequence of preforming masonry work.

Q4. spec calls for pre-mix mortar. A local mortar will be a better match than mortar sourced 800 miles away, can NHL 3.5 and a local sand be used for mortar?

A4. We will require the mortar that is specified in the specs.

Q5. structural drawings have key notes for repointing, beside the notes is the keyword "typical"; is this a 100% re-point or only in the locations notated on the drawing?

A5. The work to be performed is what is specified in the documents provided.
