QUESTIONS:
1. What is the estimated construction budget?
Answer: This information is not currently available.
2. On page 2-4.2 the bid form states that the work shall be completed within 30 days from Notice to proceed, however Page 3.1-2 the Agreement states the total time shall not exceed 60 calendar days, and on Page 4-2.1 Part 2.2 C states that the entire project should not exceed 14 calendar days. On page 4-2.2 Part 2.2 G states that work is only allowed M-F 7 AM to 7 PM with prior permission required for weekend work yet the weekend days still counts towards the above Contract durations. Part 2.3 A states that only one basin out of at a time; is this meant to be one at each plant or only one of the five at a time? Part 2.3 B states 3 days per tank. 3 days at each tank for 5 tanks is 15 days, which leaves no time for CCWA to drain and clean the tanks if the 14 day restriction is mandated. None of the above time constraints allow for submittals, approvals, or procurement of the covers. Please review and revise all these durations to be realistic and uniform. Part 2.3 means one basin out at each plant at one time.
Answer:
Page 2-4.4 states the contract shall be completed within thirty days (30) of the NTP.
Page 3.1-2 Should be change to not to exceed thirty (30) days.
Page 4-2.2 the entire project should not exceed 30 days. 4-2.2 states that work is allowed M-F 7 AM to 7PM and if needed the work would be allowed on Saturday and Sunday . Each day worked will count toward the project duration.
3. There does not seem to be sufficient detailed specifications regarding the launder cover material type, operating characteristics, or function. Below are the six sentences within the 69 pages that describes the covers and our follow up questions based upon the provided information:
