SUMMARY
Construction of the Mission Boulevard Corridor Improvements Phase 3 project from A Street to Rose Street started on July 10, 2023. The original contract allowed for 240 working days, setting the projected completion date at June 25, 2024. However, during construction, several issues arose-some initiated or caused by the City-that delayed substantial completion to April 25, 2025. These City-driven changes impacted both the construction schedule and scope, resulting in time extensions and increased costs. This increased cost paid through construction contingency exceeds the approved amount. Staff recommends that Council authorizes the City Manager to increase the construction contingency in the contract with DGC by $402,285 from $1,574,274 to $1,976,559.
Additionally, Mark Thomas, was contracted by the City to provide construction support services. The extended construction period required additional support beyond their original scope. Staff recommends that Council authorizes the City Manager to amend the PSA for construction support with Mark Thomas to increase the contract amount by $11,520 for a NTE amount of $1,791,700.
