Consideration of Amendment No. 1 with Crossland Heavy Contractors, Inc. for construction of the West Cedar Creek Sewer Interceptor Project, 1-C-011-24.
Body
________________________________________________________________________________
Summary:
This project includes the design and construction of a new gravity sanitary sewer interceptor from the City’s existing 159th Street and Cedar Lake lift stations to the south end of Lake Olathe along Dennis Avenue. At the north end of the interceptor, a new regional lift station will be constructed, and all flows will be pumped through a new force main from the lift station at Dennis Avenue all the way to the City’s Cedar Creek Wastewater Treatment Plant located on 119th Street west of Clare Road. These improvements will also allow for sanitary sewer service to areas along Old 56 Highway west of Robinson Drive that currently do not have the ability to be provided service.
On January 31, 2024, the City advertised a Request for Qualifications (RFQ) to provide Construction Manager At Risk (CMAR) services for construction of this project. Crossland Heavy Contractors, Inc. was selected as the Construction Manager and a pre-construction phase services contract was awarded by City Council on June 4, 2024.
This Amendment establishes the first Guaranteed Max Price (GMP) for the project at $1,543,553. Services include providing tree clearing along the proposed alignment, general site work, conducting pre-blast surveys of properties potentially located in the zone of impact, and the installation and maintenance of construction entrances and erosion control throughout the project area.
This project has been split into multiple GMP packages to facilitate an expedited construction schedule. The next anticipated GMP for this project will include construction of the new sanitary sewer interceptors and forcemains, along with early procurement of lift station equipment expected to have long lead times. The second GMP is expected to be presented to Council for consideration in early 2025.
It is anticipated that construction on this project will begin in Spring 2025 with completion anticipated in Fall 2026.
