Minutes from 8.25.11 Pre Bid Meeting
The City of Dover held the prebid meeting at 10:00am on August 25, 2011
Dave went over the project and pointed out possible issues:
The gas company has work to do in the project and the drainage for Kent, outfalling at 51 Applevale may need to change in the field if easements are not obtained.
The first issue raised was the bid opening date of Sept 6, the Tuesday after Labor Day weekend. They feel the prices will be higher because of the timing of getting prices from suppliers. Dave explained that that was the last day we could open and get on the next council agenda to actually get some work done this fall. I said the city will revisit that opening date.
Other questions are as follows
Q: Will they be shutting off the water main to replace the corporations?
A: Yes, hoping to coordinate to do more than one at a time.
Q: Will they be paid to remove asbestos if encountered?
A: Yes. For the hydrant replacement work and where encountered with crossings and services, etc. It is not the intent to remove long portions of the asbestos pipe if avoidable.
Q: There is a note on the plan to remove the asbestos pipe. And in the bid specs it says if the pipe is within 5 ft to remove it.
A: I will check that but I stated we don’t want to disturb the asbestos if possible and avoid it. Any other pipe within the trench area that’s not asbestos should be removed. The asbestos pipe left in place, we will cap ends and remove structures down and backfill
Q: How will they be paid for coring asbestos pipe?
A: I don’t know I will have to check and see how that’s paid.
Q: Will they have to do the excavating for the gas company?
A: Yes. Usually just around conflict with structures. The gas company should be installing/replacing their gas main and services if they are too shallow this fall and spring.
Q: Will they add an asphalt escalation clause?
A: We will investigate including one.
Q: Is the town supplying a staging area?
A: Yes, within the cul-de-sac.
Q: What is the engineer’s estimate?
A: $2,500,000
Q: what is included in the site work lump sum item?
A: Everything that’s not a separate bid item and look under the site work item for details.
Additional questions received
• Specifications indicate to expect (30) monuments that will need to be removed and reset and this work must be done by a Licensed Land Surveyor. Can this work be done by a Licensed Land Surveyor and/or Licensed Professional Engineer?
Answer: resetting of markers must comply with state law.
• Is Item 64 – 4’ DIA Sanitary Sewer Manhole intended to include the frame and cover or will all frame and covers be paid under Item 65 – Sanitary Sewer Manhole Pamrex 32” DI Frame & Cover regardless if it’s a new or existing structure?
Answer: Item 64 does not include the frame and cover. All new frame and covers are paid under item 65. No matter if they are installed on new or existing SMHs.
• A bid date extension is requested. Given the proximity of the holiday weekend and the possible effects of Hurricane Irene, receiving quotes for this project will most likely be difficult.
Answer: yes the bid opening date has changed
Other clarifications:
1. Hymax couplings are paid for separately in all cases except for New Eddy Hydrant installation cut-in-method. The Hymax couplings are included as part of pay item 15.
2. For the coring of asbestos pipe it was our intent that any coring of the asbestos pipe necessary for sewer services would be subsidiary to the sewer service connection work, whether it be subsidiary to sewer line installation or part of Item #63 (Flexible Sewer Service Saddle on Existing Sewer Mains).
