Q. Protection and Cleaning of Installed Roof Membrane: The roofing contractor is responsible for protection of installed sections of new roof membrane from staining and discoloration. Strategies for protection of installed membrane may include, but are not limited to, use of roof membranes with manufacturer-applied protective film, full coverage of installed membrane with sealed tarps, sequencing of roof membrane installation in a manner to limit tear-off dust, dirt and debris migration, and limiting traffic on installed membrane.

RFIs Submitted by Contractors:

1. RFI 1: Are we going to change the insulation install, knowing the tapered iso will create a concern at the window on Area H and at the door jam on Area O due to the tapered height at those areas on top of the R-30 insulation?

RFI 1 Answer: Yes, the insulation height and R value is likely to change to be able to accommodate the door jam and wall vent on area O and the low windows on area H to allow proper drainage.

2. RFI 2: On Area K5, is the additional R-30 insulation over existing insulation on the recover. Or is it 1 layer of insulation mechanically fastened to the existing insulation (once membrane is removed) giving it a total of R-30 value?

RFI 2 Answer: Replace any/all damaged existing insulation and install additional insulation layer(s) to the existing to achieve the R30 requirements.

3. RFI 3: Is the roofing membrane to be reinforced or non-reinforced?

RFI 3 Answer: The membrane is to be non-reinforced. Note change: Detail 1.01 language to be changed to non-reinforced. Reference Sheet A3.0.

4. RFI 4: Is there a coverboard on this project?

RFI 4 Answer: No

5. RFI 5: Is there asbestos on this project?

RFI 5 Answer: Royal Oak Schools to furnish asbestos reports.

6. RFI 6: Regarding the full tapered roof areas. What R-value are we needing to meet and does it need to be min or avg or are we just figured a full tapered insulation system with NO base layers of insulation. Due to the height of the windows on area H and the door on area O. there is not a lot of room to work with only 3” of exposed flashing with the existing roof being 3”.

RFI 6 Answer: Attain R-Value for existing conditions.

7. RFI 7: For Area H (at the window) the height is about 6" of height from deck to flashing height.

The Min R-30 value and tapered will be about 11.7" thick. RFI 7 Answer: Sometimes an R30 cannot be obtained on certain applications. The contractor is to provide a suitable tapered system for proper drainage for this roof area even though an R30 is not achievable.

ADDENDUM 1

ADDENDUM 1 Page 2 of 2

8. 8. RFI 8: For Area O (at the door jam) the height is about 6" of height from deck to flashing height. The min R-30 value and tapered will be about 12" thick. RFI 8 Answer: Sometimes an R30 cannot be obtained on certain applications. The contractor is to provide a suitable tapered system for proper drainage for this roof area even though an R30 is not achievable.

4. CHANGE: A2.2 Roof Plan: Removed reference to KN1 on drawing. See markup in red.

5. CHANGE: A1.0, A2.0, A2.2: Underlayment “as required” language removed.

6. ADD: A2.3 Tapered saddles added to drawing.
