Council approves change order to replace 142 obsolete traffic signal heads under HSIP 11C
Summary
Council approved a change order to replace 142 obsolete traffic signal heads found during field verification for the HSIP 11C project; the change order totals roughly $107,129.84 with the city's 10% match just under $11,000 and staff recommended a 10% contingency. The revised construction budget remains within the HSIP grant.
City staff presented a field evaluation of the Highway Safety Improvement Program (HSIP) Cycle 11C citywide traffic signal hardware upgrades and reported that of 778 signal heads included in the bid proposal, 142 are obsolete and could not be retrofitted. Staff said the proposed change order would remove and replace those 142 obsolete heads, make adjustments for 39 heads already upgraded, and that the change order amount shown in staff materials is $107,129.84 (the transcript rendered the figure in two parts; staff clarified the full amount in the presentation). The city's 10% match was described as 'just under $11,000.'
Staff recommended authorizing change order number 1, revising the construction budget and adding a 10% contingency because of the number of intersections and legacy hardware variations. The project remains within the HSIP grant award from Caltrans, which funds roughly 90% of the project; the city provides the other 10%. Councilmember Lam moved to approve the change order, Mayor Pro Tem Gutierrez seconded, and the motion carried unanimously (all ayes).
Staff stated lessons learned: more detailed field verification during design would reduce similar oversights on legacy infrastructure projects.
