Description/Analysis
Issue Detail: Staff recommends Council approve Change Order No. 3 with TNT Industrial Contractors, Inc. (City Agreement No. 2021-0728), for additional work due to unforeseen site conditions.
Policy Considerations: City Council approval is required when the total change orders exceed 8% of the original project budget. This work is consistent with the criteria set forth in the Department of Utilities (DOU) Capital Improvement Project Programming Guide to rehabilitate, replace, and expand critical infrastructure to ensure reliability and safety.
Economic Impacts: None.
Environmental Considerations:
California Environmental Quality Act (CEQA): The subject projects were reviewed and determined to be categorically exempt from the California Environmental Quality Act (CEQA). The projects include the replacement of existing deteriorated sump systems where the new sumps systems will be located on the same sites as the systems replaced and will have substantially the same purpose and capacity of the systems replaced (CEQA Guidelines Section 15302(c)).
Sustainability: The proposed project is consistent with the 2035 General Plan U4.1.1
Adequate Drainage Facilities as it improves pumping capacity for peak storm flows, improves service and infrastructure reliability, and increase redundancy.
Commission/Committee Action: Not applicable.
Rationale for Recommendation: The Department of Utilities (DOU) owns, operates, and maintains the 106 drainage sump stations within the City. The outfalls from the sump stations are the single point of discharge for storm water from their respective basins. The outfall pipes penetrate and cross major levees along the Sacramento River, American River, Natomas East Main Drainage Canal, Arcade Creek, and Morrison Creek.
City staff has an ongoing requirement to inspect all outfalls that penetrate and cross major levees on a 5-year cycle as mandated by the US Army Corps of Engineers (USACE). During inspection of the outfalls, several were noted to be in failed condition or in danger of imminent failure. Condition of the identified outfalls range from failed liners to heavy corrosion/spalling to large perforations. As a result, sinkholes have been observed at these outfalls. Some outfalls also need pipe sections replaced to match partial pipe replacements done by the USACE. TNT Industrial Contractors is currently under contract with the City to replace whole or partial force mains for sump stations 58, 102, 103, 154, and 159.
Due to unforeseen site conditions, the project construction schedule required that the work stop at Sump 102 for the duration of the 2021-2022 rainy season. These unanticipated conditions required demobilization and remobilization efforts once construction was permitted to begin again. This council request also resets the City Manager’s signing authority
Financial Considerations: The original not-to-exceed amount of the contract was $2,244,502. The net change by previous change orders in the amount of $169,302 increased the contract not-to-exceed amount to $2,413,804. Proposed Change Order No. 3 in the amount of $32,097 would increase the contract not-to-exceed amount to $2,445,901.
There are sufficient funds in the Drainage Sump Replacement/Rehabilitation Program (W14130600, Fund 6011) to execute this Change Order.
There are no General Funds allocated or planned for this project.
