Bid item #12 is a lump sum bid item for “Cleaning and prepping exposed steel reinforcement and steel wire.” Page 9 of 35 in the specification acknowledges there are “a few sections of pipe and portions of the blind 90 degree bend that may have exposed steel reinforcement and/or steel wire.” The spec says “after the sewer cleaning the contractor shall review the condition of all exposed steel.” If cleaning reveals additional locations of steel that require prepping, will there be additional compensation for this work that’s not currently identified?
Response: Based on our review of the sewer videos LCPW anticipates the following areas will have to prepped because of exposed steel:
1) The bling 90 degree bend
2) 50 LF of pipe immediately adjacent and upstream of the blind 90 degree bend on Wilson
3) 50 LF of pipe immediately adjacent and downstream of the blind 90 degree bend on Rollins
4) One section of pipe on Rollins a distance west of the blind 90 degree bend.
If cleaning revels additional locations there would be additional compensation.

Q#1: We’ve built a lot of constructions projects and haven’t had portable facilities on-site during our project. Can you change this from a requirement to a recommendation?

Q#2: At the 13 minute mark of the video entitled “MH 72BB01 to MH 72AA29 (blind 90 degree bend) 2021-01-04”, the pipe makes a 90 degree turn to the left. There is an elevated bench with flow coming in from the right side. Does the scope of this project include any rehabilitation of that elevated bench or associated chamber or is this project strictly rehabilitating the pipeline? Can you clarify the exact scope of this project when talking about the “blind 90 degree bend?”
