Home My WebLink AboutWRH CO #2 TITUS Cont. #975 - 9.16.2024,4=COM August 30, 2024 Mr. Jesse Gaherty Waste Management Services City of Waterloo 3505 Easton Avenue Waterloo, Iowa, 50702 Subject: Titus Lift Station and Force Main Change Order No. 2 City of Waterloo, Iowa City Contract No. 975 AECOM #60726355 Dear Mr. Gaherty: AECOM 501 Sycamore Street Suite 222 Waterloo, Iowa 50703 www.aecom.com Attached is Change Order No. 2 for the Titus Lift Station and Force Main project submitted by WRH, Inc. 319-232-6531 tel 319-232-0271 fax The following are the details for the requested changes. • Final Completion Date — CAR No. 7 - WRH has requested to add 31 calendar days to the project. This time is for work approved with Change Order No. 1. We feel this time addition is justified. • Bedrock was encountered at Grandview Avenue that prevented directional drilling the force main. It takes more time to remove and replace the pavement and open cut the force main across Grandview Avenue than installing by direction drilling. • Manhole No. 2 was added to the project to connect the force main to the gravity sewer at the south end of the project. Additional time is needed to do this work. • Bid Item No. 44 - 16' Chain -Link Fence Gate — CAR No. 8 — MidAmerican Energy requested that the transformer be placed in the swing path of the east side gate. To accommodate this request, we decided to change the gate from a swing gate to slide gate so the gate can be fully opened. This change is an addition of $1,942.50. • Bid Item No. 49 — MidAmerican Transformer Pad — CAR No. 10 — The MidAmerican Transformer Pad was not included in the design. It is typically unknown at the time of design whether MidAmerican Energy will require a concrete pad for the transformer or if the transformer will be located on a power pole. MidAmerican Energy requested a ground mounted transformer. This work is required to power the lift station. This change is an addition of $25,845.23. AECOM recommends the City approves Change Order No. 2 for the addition of $27,787.73 and a revised total contract cost of $6,270,696.88. The increase is 1.40% of the original contract.
