from Paco. Due to the length of time to decide on the approved pump, the contractor's quote for the bid pumps expired, resulting in additional costs, During the review
process, a number of pump manufacturers were discussed. Quotes were received for providing Cornell pumps for both projects. Based on cost of the Cornell pumps m
approximately $10,000 In added costs, the use of Paco pumps was approved, The pumps in Allentown were increased in size from 2 to 3 horsepower, based on further

force mains had to be removed with the excavation of the 8' PS, causing slow down, extra work and eventual disposal of the removed pipe. The sewer main between MH 5C
PL -03 and 50 PL -01 was lowered from 1.0% to 0.4 As a result, the 8" stub out of MH 50 PL -01 was in direct conflict with the two 12" abandoned force mains, which had
