RECOMMENDATION
Staff recommends that City Council approve Amendment No. 4 to the City's professional engineering services contract with HDR Engineering (HDR) for the W.O. 19-12: West End Reservoir Project in the amount of $1,991,300.
BACKGROUND (Consistency with Adopted Plans and Policies, if applicable)
| HDR's preliminary design contract for the West End Reservoir in the amount of $1,564,000 was approved by Council on March 25, 2019. Staff determined during preliminary design that a new river intake, pump station and pipeline is the only option that provides reliable year-round flow to the reservoir and offers the City complete control over the raw water source, pumping and delivery of water to the reservoir. Other options evaluated included various flow diversions from Canyon Creek and the BBWA Canal. In follow-up to this determination, Council approved Amendment No. 1 in the amount of $2,096,200 on April 13, 2020 to conduct preliminary and final design of an expandable raw water intake structure and pump station at the Yellowstone River near the Duck Creek Bridge, a 4-mile long water transmission pipeline from the pump station to the West End Reservoir site, all required permitting, electrical, controls and instrumentation, and a shale material processing pilot study. Amendment No. 2 for $698,400 approved in April 2019 provided additional topographic survey and geotechnical services in support of the reservoir design, and Amendment No. 3 for $73,900 approved in February 2022 provided additional permitting, geotechnical, and surge analysis services for the river intake, pump station and pipeline. Amendment No. 4 now under consideration would add the following to HDR’s scope of services: Intake/Pump Station Project · bidding, construction contract administration, field inspection, training, start-up, warranty and application software programming services based on a 21-month construction period to substantial completion, · permitting and design assistance for a Fish, Wildlife and Parks (FWP) fishing access site (FAS) to be located adjacent to the intake/pump station on City-owned property. The US Army Corps of Engineers has required the FAS to be permitted with the City’s project, but it will not be included in the City’s construction contract. FWP will build the FAS under their own separate construction contract. City staff is currently developing a Memorandum of Understanding with FWP to outline compensation for the permitting and design assistance as well as FWP’s future use and maintenance of the FAS, and · boundary survey, geomorphology study, and permitting assistance in the area of proposed in-river rock structures to stabilize the main river channel near the intake/pump station. Raw Water Pipeline Project · construction contract administration, field inspection, close-out and warranty services for the Raw Water Pipeline project based on an 8.5 month construction period to substantial completion, · General Contractor/Construction Manager (GC/CM) selection and coordination assistance. On August 23, 2021, City Council approved a Pre-construction contract with COP Construction and then approved a GC/CM construction contract with COP on July 25, 2022, and · additional pipeline survey, permit coordination, and crossing assistance in the I-90/Montana Rail Link area. Reservoir Project · installation of 8 groundwater monitoring wells. The majority of this work under this amendment was planned. When these projects are started, we are unable to determine a scope of services and associated fee until the design is completed to a certain point. This amendment includes the remainder of the planned work for both the intake, pump station and raw water pipeline. There will be at least one more amendment for the reservoir. |
ALTERNATIVES
City Council may:
- Approve Contract Amendment No. 4 with HDR Engineering, or;
- Not approve Contract Amendment No. 4. If this amendment is not approved, the City will be unable to continue the work to construct the facilities needed to reliably supply raw water to the proposed Billings West End Reservoir.
FISCAL EFFECTS
The W.O. 19-12: West End Reservoir Project original professional services contract and three (3) amendments to date have a value of $4,432,500. Proposed Amendment No. 4 in the amount of $1,991,300 would increase the total contract amount to $6,423,800. Water funds budgeted in FY23 are adequate and will be used for this project amendment.
