FROM: Himanshu H. Mehta, PE, Managing Director, Solid Waste Disposal District
DATE: September 24, 2025
SUBJECT: Request for Approval of Change Order No. 2 to CK Contractors and Development (CK) for Landfill Automated Scale Lane Project
__________________________________________________________________
BACKGROUND
The Solid Waste Disposal District (SWDD) staff utilized the Department of Utility Services' labor contract (originally approved on July 7, 2020, and ending on July 6, 2024) to authorize the construction of the Automated Scale Lane Project that was designed and permitted by Kimley-Horn and Associate, Inc. (KHA) under separate authorizations from the SWDD Board.
Specifically, CK Contractors and Development (CK) was issued a Purchase Order (PO) #98761 for the Automated Scale Lane project in the amount of $475,176.89. On March 11, 2025, the SWDD Board approved Change Order No. 1 in the amount of $229,026.47 to CK for a total project cost of $704,203.36.
To enhance customer service, and provide proper ingress and egress, lift arms, and roadways, as well as additional cameras, staff requested additional scope to the project.
CK has requested Change Order No. 2 to complete the project, which requires SWDD Board approval.
ANALYSIS
The current in-bound and out-bound lift arms are out of service, and the existing roadways leading to these scales need to be improved. Additional cameras are also needed to manage the new automated scale. These improvements are best facilitated as part of the automated scale lane project. Given that CK and their subcontractor, Summit Construction, is already mobilized to the site, staff requested these additional services to the existing project. CK has submitted the attached Change Order No. 2 in the amount of $293,429.40.
The purpose of this change order is to address multiple items associated with the function and longevity of the Automated Scale:
1. Additional cameras and gates - Cameras are necessary to capture images of vehicles, including license plates and contents. Gates are to be used to control the flow of traffic across the scale. While these items are necessary for the operation of the scale, they require additional materials, conduit, wiring, and labor to install and program for proper use.
2. Approach slab - A concrete approach slab is necessary to carry the static and dynamic loads of the large heavy vehicles utilizing the scale to avoid future asphalt damages and repairs as seen in the current inbound lane, which is scheduled to be replaced by a similar approach slab between December 2025 and January 2026.
Staff also recommends a contingency of $30,000 for a total change order increase of $323,429.40 for a new total project cost of $1,027,632.76.
BUDGETARY IMPACT
Funding, in the amount of $323,429.40, for the SWDD Landfill Improvement project is budgeted and available in the SWDD/WIP/Landfill Automated Scale Systm account, number 411-169000-22001, which is funded from SWDD assessments and user fees.
