The investigation determined that at least one sewer pipe in the <br /> area has collapsed. The collapse has caused the pavement problem in the intersection, as the <br /> ground under the pavement has continued to collapse and get washed down the sewer. The <br /> collapsed line serves the four curb intakes in the intersection of Main and William, plus an area <br /> drain in the parking lot of the Dean Witter office building. This collapsed line may have <br /> contributed to floodin�problems at the office building. <br /> The project was advertised and bids were received and opened on Wednesday, October 8, <br /> 1997. The results of the bid opening(a bid tabulation is attached) are as follows: <br /> Compared to <br /> Engineer's Est. , <br /> I Bidder Bid Price Over(-Under) I <br /> Engineer's Estimate $ 76,045.00 --- <br /> Sewer Incorporated $ 52,240.00 (31.30) <br /> Staff has reviewed the single bid and determined that the bid is reasonable for the scope of <br /> work. The work involves the abandonment of existing sewers; the installation of new, larger <br /> diameter sewers and the inspection of other existing sewers in the area that have not been <br /> accessible for inspection. <br />
