Inquiry #1: Project 07-1W5304 advertised this morning and the pdf of the plans is available – but not the specifications file.

When will the specifications file will be available?

Inquiry submitted 03/18/2013

Response #1:The Contract Specifications have been placed on-line.
Response posted 03/20/2013

Inquiry #2: Specification section 15-6.11B(1) on page 19 states that at location 1, the minimum wall thickness for the CIPP is 0.7 inch, which would equate to 17.8mm. At location 1, there is one 60" pipe & four 18" pipes that are required to be lined with CIPP. While 17.8mm may be an appropriate minimum thickness for 60" diameter CIPP, it is far too thick for 18" diameter CIPP and will likely prove to be problematic to install. Please modify the minimum CIPP thickness requirement in section 15-6.11B(1) to differentiate between the 18" & 60" pipelines and provide a lower minimum CIPP thickness for the 18".
