1. After reviewing the report on the current roofing systems adhesion problems I would like to know if you would consider installing a vapor barrier to your system?

It has been my experience with a concrete deck it is best to fully adhere Carlisle 725R vapor barrier with cav grip primer- adhesive followed by fully adhering the insulation and the membrane. The cost is more but the system works very well. Please advise.

VA Response: Contractor selected system shall comply with manufacturer recommendations and warranties.

2. Does the Superintendent need to be directly employed by the Prime Contractor?

14. Section 07 01 50.19 Preparation for Re-Roofing states "Perform moisture test according to ASTM D4263-83 (2018) each day for each separate roof area." Here's a link to one of many manufacturers websites that details what this ASTM spec consists of. https://usa.sika.com/en/construction/floor-wall/resource-center/product-industry-news/concrete-test-methods.html

We cannot leave the roof deck exposed to the elements each day for 18-24 hours to perform this testing. Please advise.

This roofing system consists of mechanically fastening the first layer of insulation to the concrete deck then adhering all other layers and adhering the 60 mil EPDM membrane. I do not see an air and vapor barrier on the concrete deck. As a roofing contractor, we feel the manufacturer is going to want this installed. Please advise.

VA Response:

In response to the question’s first and second paragraphs, specification section 07 01 50.19 Preparation for Re-Roofing will not be amended in response to this RFI question. As indicated in the Roof Condition Assessment Report, the roofing deck was saturated. Installation of a new roofing system with saturated decking will result in unsafe conditions.

The COR will not dictate means and methods, to include but not limited to protecting the structure during intermediate phases or achieving a dry deck surface. Those means and methods should be included in the bids and during project submittals for review against project and safety requirements.

Regarding the question’s paragraph 3, Contractor selected system shall comply with manufacturer recommendations and warranties.
