The test bores which <br /> were made available to the bidders did not indicate rock <br /> although new test bores by S & ME engineers are on either side <br /> of the sewer center line revealed rock of sufficient hardness <br /> to stop the boring procedure originally employed. <br /> BACKGROUND: In order to complete this leg of the sewer, a new bore must be <br /> accomplished by starting a new bore with a 36" casing so rock <br /> and dirt may be jacked and hand mined to a point of connection <br /> with the eighteen inch casing already installed. As you will <br /> note, there is a fixed price for dirt and still another price <br /> for rock. The total cost not to exceed is $10,471. 00 and we <br /> expect the cost to be something less than this, since the dirt <br /> and rock will be removed on a per unit cost and the enginer <br /> will be allowed to make that determination. There is an <br /> extension time of twenty calendar days added to the end of <br /> Phase II. <br /> RECOMMENDATION(S) : Approve change order in the amount of $10,471. 00 and <br /> extend contract date by 20 calendar days at the end of <br /> Phase II. <br />
