File Number: 23-171 attributed to improper turning, driving under influence, and low visibility of traffic signals, especially when passenger cars were traveling behind big vehicles at relatively high speeds. Staff evaluated collision patterns in the five-year period and determined that the intersection warranted a spot improvement by upgrading the traffic signal equipment as well as enhancing traffic signal operations. More specifically, City staff has identified the following three countermeasures that are deemed necessary: Provide protected left turn traffic light phase (left turn lane already exists); Improve signal hardware to the current standards; and Provide Advanced Dilemma Zone Detection for high-speed approaches. Analysis On April 5, 2023, staff opened bids for the subject project. Seven bids were received with bids ranging between $668,487 and $1,019,529 . Staff determined that Gruendl Inc. dba Ray’s Electric (Ray’s Electric) is the apparent low bidder based on the total bid amount. The pre-bid Engineer’s Estimate for construction was $615,955. Staff recommends the award of a construction contract to Ray’s Electric in the amount of $669,487. Staff verified that Ray’s Electric has a valid Contractor’s State License Board license and is registered with the California Department of Industrial Relations. This project has a Disadvantaged Business Enterprise (DBE) participation goal of 19%. The DBE documentation for the three lowest bidders was either received by the City as part of the bid package or within two days of the bid opening. The DBE documentation submitted by all three contractors was reviewed and found to be acceptable. This project is not subject to the provisions of the Community Workforce Agreement (CWA) or the City’s Local Inclusion Policy Ordinance because it is a Federally funded project. As is standard in the construction industry, staff balanced site investigation costs with the risk of finding unforeseen conditions during construction as well as the design costs with the level of detail on the plans. As a result, unforeseen conditions may be encountered during construction and plan details may need to be adjusted or clarified. To minimize a delay of the project and ensure that the scope of work is adjusted as needed to provide the highest quality project, staff requests that the City Council authorize the City Manager or her designee to negotiate and approve individual change orders up to 5% ($33,474) of the original contract amount. In addition, staff requests authority to negotiate and approve cumulative change orders up to 25% ($167,372) of the original contract amount to ensure efficient completion of the project on budget and on schedule. Complete Streets features will be constructed as part of this project. $99,821 of the money appropriated to 143-38-392 will be utilized for the construction of accessibility features related to Complete Streets.
