TITLE: Intersection Traffic Signal System—Major
Replacements and Upgrades (Rengstorff
Avenue and Latham Street), Projects 18-
27 and 22-15—Construction Acceptance
RECOMMENDATION
Accept Intersection Traffic Signal System— Major Replacements and Upgrades (Rengstorff Avenue and Latham Street), Projects 18-27 and 22-15, and authorize the final contract payment.
BACKGROUND AND ANALYSIS
“Acceptance” of a construction contract is a legal event recognized by State Law when the City verifies that the contractor has satisfactorily completed a public project. Once accepted, the work on the public project is complete and other actions occur, such as final payment to the contractor and the release of bonds obtained by the contractor that ensure completion of the project.
Following acceptance, the City becomes responsible for maintenance of the public project.
On October 25, 2022, Council took the following actions on the project:
1. Approved plans and specifications for Intersection Traffic Signal System —Major Replacements and Upgrades (Rengstorff Avenue and Latham Street), Projects 18 -27 and 22-15, and authorized staff to advertise the project for bids.
2. Authorized the City Manager or designee to award a construction contract to the lowest responsible bidder if the bid was within the project budget.
The contract was awarded to Columbia Electric , Inc. of San Leandro at the low- bid price of $941,831. This project included the following improvements:
• Improved safety by eliminating the bicycle, pedestrian, and left-turning vehicular movement conflicts by replacing the existing six-phase traffic signal with an eight-phase traffic signal;

• Restriped westbound and eastbound Latham Street to have dedicated left -turn lanes and shared through and right- turn lanes, which was needed for eight -phase traffic signal operation;
• Installed bicycle lane green markings through the intersection on southbound Rengstorff Avenue crossing Latham Street to guide bicyclists on a direct path through the intersection;
• Removed and reconstructed two curb ramps to conform to ADA standards;
• Installed high-visibility crosswalks; and
• Installed an advanced technology video detection system. The system's combined detection and communication features utilize artificial intelligence (AI) to support real- time management of traffic operations. The AI detection provides lane -closure alerts, signal outage alerts, and communication alerts to staff and allows remote evaluation of some of these events to help the City restore traffic operations more efficiently.
The final construction cost of $ 874,468 is within the construction contract amount of $ 941,831 and included two contract change orders for the total amount of $ 31,432 and a final quantity adjustment change order, resulting in contract savings of $67,363. All construction work has been completed in accordance with the approved plans and specifications.
