1. The specs call for 4” aluminum guters. To put this in perspec�ve, prac�cally ALL residen�al roofing is done with at least 5” guters and 2”x3” downspouts. This is a very large roof and it will be metal as well. In order to handle the watershed from a roof that is over 4 �mes the average residen�al home, no less than a 6” guter should be used as well as a larger 3”x4” downspout. The guters should be 6” with 3”x4” downspouts. The note on the roofing typical detail sheet (sheet 6) which calls out for 4” guters is in error.

2. The specs call for the replacement of fascia. The term “fascia” is a very broad term and needs to be defined.

a. Does it mean merely to wrap the exis�ng fascia with 24 gauge metal? OR…. The fascia work item refers to removing the exis�ng metal fascia wrap and rewrapping with new 24 gauge metal.

b. Does the exis�ng fascia need to come off and then the sub-fascia be wrapped with metal. OR…

c. Is the exis�ng fascia going to be removed and replaced with wood fascia, mdf or some other facsimile there of? OR…

d. Is there even sub-fascia on the building at this �me? If so… what size? Is it the right size to fit stock metal fascia wrap or…will it require a special bend to accommodate.

3. The specs call for BOTH “step flashing and counter flashing” along where the slopes of the roof meet the wall. Step flashing is only used in the applica�on of shingles and not metal to use BOTH step and counter flashing for this applica�on doesn’t make sense. Counter and step flashing as called out for in note 3 on sheet 4 should read “Install rake flashing where roof meets ver�cal wall”. Note 5 on sheet 5 should also read “Install rake flashing where roof meets ver�cal wall”.

4. The specs call for 24ga PBR. Do the trim pieces need to be 24 ga as well? Yes, trim pieces should also be 24 gauge.

5. Is the current roof decking tongue and groove? The replacement calls for 5/8" decking. The roof decking on the original building is 1”x6” tongue and groove planking. The roof decking on the addi�on (East Eleva�on) is 5/8” OSB. Sheathing replacement is an Actual Quan�ty pay item and replacement material will be in kind, either solid planking or 5/8” sheet material depending on where the material is needed.
