Consideration of Amendment No. 4 with Crossland Heavy Contractors, Inc. for construction of the West Cedar Creek Sewer Interceptor Project, PN 1-C-011-24.

________________________________________________________________________________
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 north side of 135th Street. From there, it will return to a gravity interceptor 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 and areas north of 135th Street 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.
The project has been split into multiple Guaranteed Max Price (GMP) packages to facilitate an expedited construction schedule. The first three GMPs established for this project are as follows:
GMP No. 1 - $1,543,553.00: Work includes pre-blast survey, tree clearing along the alignment, and general site work.
GMP No. 2 - $30,044,776: Work includes 5.6 miles of gravity interceptor sewer, 2.1 miles of forcemain sewer, four auger borings, and blasting and excavation of the lift station site.
GMP No. 3 - $4,781,574: Work includes structural concrete for the new lift station and procurement of some major equipment and process piping.
This Amendment establishes the price of GMP No. 4 at $4,525,586. Work in this GMP includes the lift station building, all remaining equipment, installation of piping and electrical systems, and all site improvements. We anticipate this being the final GMP for this project.
Work in GMP No. 1 is complete and work in GMPs No. 2 and No. 3 are both underway. Project completion is currently anticipated in Fall 2026.
