MEMO
To: Honorable City Council
From: Christiana Giedd, Associate Civil Engineer
Date: 07/26/2023
Subject: Fleet Maintenance Facility Change Order 3
RECOMMENDED ACTION:
Approve Change Order No. 3 for electrical revisions and revisions to accommodate SSJID, MID, and Fire Department requirements in the not to exceed amount of $132,150.00 (funding sources:
Corp Yard AB1600 Fund, Measure K Transit, Enterprise Capital Funds, and General Capital Fund).
BACKGROUND:
The Fleet Maintenance Facility Project was awarded to Diede Construction, Inc. at the December 13, 2022 City Council meeting for an amount of $11,156,000. The Fleet Maintenance Facility Project will involve the construction of a 12,500 square foot maintenance building and parking lot.
At the March 14, 2023 City Council meeting, Council approved Change Order No. 1 in the not to exceed amount of $288,622 for raising the elevation of the existing berm at the Wastewater Treatment Plant disposal ponds in order to provide additional storage capacity.
At the June 13, 2023 City Council meeting, Council approved Change Order No. 2 in the not to exceed amount of $1,466 for additional survey staking.
DISCUSSION:
The Fleet Maintenance Facility Project required design changes due to electrical revisions and requirements from SSJID, MID, and the Ripon Consolidated Fire District, as summarized below:
Project changes related to electrical revisions: The bid set for the project did not include the electrical connection from the on-site transformer to MID’s transformer. Additionally, the secondary cable and primary conduit connecting the building to the on-site transformer were not included in the bid. A slight cost offset is included from the removal of electrical requirements from the south gate. The additional cost related to these changes is $108,550.
Project changes related to SSJID requirements: SSJID has a pipeline easement that runs through the project site. The pipeline depth is such that the Fleet Maintenance Facility project had to be revised to include increased driveway concrete thickness, additional storm drain piping, elevation adjustments, additional catch basin installation, and slurry to achieve compaction over the SSJID pipeline. The additional cost related to these changes is $30,492.
Project changes related to Ripon Consolidated Fire District: The Ripon Consolidated Fire District requested the fire department connection be installed on the backflow preventer rather than the building. The additional cost related to this change is $1,795.
Project changes related to MID: MID has a power easement that runs through the southern border of the project site. The easement conflicted with the location of the proposed project fencing. To accommodate the easement, the project fencing was modified to connect to the fence on the south of the property rather than including an additional fence at the south of the property. The cost savings related to this change is ($8,687).
The additional work is to be billed at a cost not to exceed $132,150.
FISCAL IMPACT:
The attached Change Order No. 3 is in the amount of $132,150 and will be allocated to the Corp Yard AB1600 Fund (47.0%), Measure K Transit (7.4%), Enterprise Capital Funds (15.8%), and General Capital Fund (29.8%). The amended construction contract price is shown in Table 1.
On December 13, 2022, City Council approved the total cost of the Fleet Maintenance Facility Project which included $1,115,600 for construction contingency. Change Order No. 1 did not utilize the project contingency because the work was performed at the Wastewater Treatment Plant disposal ponds. The total remaining contingency after subtracting Change Orders No. 2 and 3 is $981,984.
