Overall scope The project is to replace a 12” water main on Fair St beginning at College St., and on King Ave. This equals approximately 2700’ of 12” pipe. There is also a 6” water main on Omer and Baril, and a 2” poly main for four houses on Omer. Temporary lines will be installed by Lewiston Water & Sewer ahead of time, and then all three mains will be shut off at the same time. ---PAGE BREAK--- 2 3. Sequence of Construction a. Temporaries: as soon as the weather permits, LW&S will begin to install temporary lines. There is a hydrant at Main St/King Ave for the temp down to Mollison. They will cut in the new valves on Ralph, Judkins, and Mollison and then tie in all temporary services. This is expected to take about three weeks. There will be no temps on Omer and Baril as there is enough room. At the end of the project, all services need to be replaced to property line at curb stop. While the temps are being installed, the contractor can install the tapping sleeve at Montello/Baril and install Omer and Baril mains. The south side of Fair St. already has new services and will be temporarily fed through the sillcocks – they do not need to be replaced. They will be extended from old to new main with a coupling. There are three houses on the north side of Fair that have not had services replaced. A temporary service will cross King Ave at Main St. and at two side streets. There will also be one temp trench on Mollison. All temp trench pavement is hand placed. Next, the 12” can be installed on College and Fair up to Montello nursing home. Do not want to interrupt nursing home. Tie in before continuing on. The hook-up for Montello Heights will need to be done after 8:00 p.m. and be coordinated with Montello. Then all three mains will be killed and the project continues. This is spelled out in Division 10 of specifications. The City will remove the temporary services. Any items that the City has installed that need to be removed during the project will need to be stockpiled and returned to City. b. The City will do the 6” and 2” taps, with the Contractor doing the excavation. The City will supply all water materials – pipes, valves, fittings and services. Contractor provides thrust blocks. c. Old mains: Old mains need to be removed if in the same trench as the new main. There is a note in the specs about “abandoned 6” mains.” There are two of these mains. If they get broken, they must be cut and capped. If not broken, they can just be left alone in place. 4. Remove old main only when it is in the same trench 5. Fair St. services: Item 70.6 says contractor is going to connect copper to main in place, but elsewhere in the plan it says all have to be brought back to curb stop. All connections, except for the new services on the south side of Fair St., have to be brought back to the curb stop. 6. Taps- City to do 2” and 6” taps Other than these, the contractor is responsible for all service taps. There is only one tapping sleeve as noted on page 10-6 of the specifications. 7. Trench restoration/paving, curb, sidewalks (incl. temp trenches), asphalt escalator: ---PAGE BREAK--- 3 Most of the trench paving that needs to be done for the temporary services will be driveways (about 14” wide, 2” deep). The contractor is responsible for all trench restoration and paving, including the temporary main trenches. Most of the temp paving is hand placed. An asphalt escalator has been included in the bid. Try to pave half of the project at a time so the whole area is not exposed gravel all summer. There are some areas on King with bituminous curb, and there will be some sidewalk reconstruction. 8. Record drawings (tie sheets): At the end of Division 10, there are record sheets. The City will provide a blank sheet for every house and the contractor needs to complete them for each service. The contractor will have to find and cut each service – can’t pull pipe. There is no way of knowing where a service is on the 12” and 6” mains; may have to dig hole on other side of street to get to a service. There will be three curb stops – two will show and the third will be on top of poly. The blue line is on the City side, the green is on the property owner side. 9. Traffic: The plan calls for road closures along the routes as needed, except for keeping a lane open on College St. There are plenty of side streets for detours. Flaggers will only be needed for the College St. lane closure. A Traffic Plan will need to be submitted when getting the street opening and excavation permits at City Hall. There will be no fee for the street opening permit. 10. Testing: The Contractor is responsible for chlorinating, pressure testing, and delivering sample to lab. The City needs to be present to witness the pressure test. 11. Questions 1. Disposal of pavement: can pavement be disposed of at a place other than Gendron? Jeff will double check on this and clarify it. 2. Bid security: due to the size of this project, a bid security of 5% is being required rather than the usual 10%. 3. The project must be completed by September 20, 2013. Project should be started as soon as weather permits and the frost is gone. If planning to start later, it must be coordinated with LPW. 4. Engineers estimate is $575,000. If any of the meeting participants feel that the above is not an accurate representation of what was discussed at the meeting, they should contact Jeff Beaule, Project Engineer at 513-3003, Ext. 3416.
