/ROUTE 60 WATERLINE PROJECT - CHANGE ORDER NO. 2, CONTRACT NO. 1 - <br />CALDWELL TANKS <br />The Board reviewed utility staff memo, as follows: <br />TO: The Honorable 2.1embers of DATE: December 19, 1984 FILE: <br />The Board of County Commissioners <br />THRU: Terrance G. P nto <br />Utility Service Director <br />SUBJECT: CHANGE ORDER NO. 2 ON PROJECT <br />U84-1, .CONTRACT NO..1 WITH.CALDWEI <br />TANKS, INC. <br />FROM: Joseph A. Baird REFERENCES: <br />Assistant Utility Director <br />DESCRIPTION AND CONDITIONS: <br />Change Order No. 2 for Caldwell Tanks, Inc., includes the following <br />modifications to the original contract: <br />1. The foundation of the new 750,000 gallon elevated storage <br />tank on Route 60 was bid originally with 106 piles of 45' <br />lengths each. The results of the test piles indicated that <br />a lesser length could be used on many of the piles. The total <br />reduction in length from all 106 piles was 204 feet yielding <br />a reduction in the contract amount of $816.00 in the contract <br />price. <br />2. The elevated tank contract was originally bid with a rein- <br />forced concrete floor in the tank as an alternative. The floor <br />was bid separate from the base contract in order that it could <br />be easily removed from the project if sufficient funds were <br />not available for the total Project. A reinforced concrete <br />floor will reduce the problem of corrosion in the tank. Since <br />the tank contract did, infact, meet the project budget, it is <br />felt that the additional $7,200 for a reinforced concrete <br />floor in the tank is a prudent expenditure. <br />The net effect of both the reduction in the length of pilings that will <br />be necessary and the addition of a reinforced concrete floor in the <br />elevated tank, requires an increase of $6,384 on the contract price <br />of Caldwell Tanks, Inc., original contract. <br />ALTERNATIVE AND ANALYSES: <br />1. Construct the elevated tank without a reinforced concrete floor <br />in the tank. <br />2. Construct the elevated tank with a reinforced concrete floor <br />that will reduce the problem of tank corrosion. <br />RECOMMENDATION: <br />We recommend that Change Order No. 2 for Caldwell Tanks in the <br />amount of a $6,384 increase be approved. <br />91 <br />JAM 2 1985 BOO' <br />KPaF. <br />I <br />
