AMENDMENT NO. 1 TO CONSTRUCTION CONTRACT WITH VINCOR CONSTRUCTION, INC. FOR THE AGUIRRE BUILDING RENOVATION PROJECT, CITY PROJECT NO. 26-503

On July 21, 2026, the City Council approved awarding a construction contract to Vincor Construction, Inc for $121,889.34 for the Aguirre Building Renovation Project. The scope of work involves replacing the countertop, sink, and flooring in the rental building to enhance functionality and aesthetics. During construction, the project team encountered unanticipated high humidity levels during moisture testing and unforeseen mold during the demolition work including areas of water damage that needed to be replaced. The work to address the mold included a mold survey, clearance, abatement, and drywall repairs.

Staff recommends the approval of Amendment No. 1 to the subject agreement for the additional work related to address the mold for the Aguirre Building Renovation Project. As a result of these changes, construction costs are expected to go beyond the original 10% construction contingency amount of $12,188.93 by an additional $8,168.66, totaling $20,357.59 or 16.7% for a total construction contract amount of $142,246.93.

It is recommended that the City Council:

1. Adopt Resolution No. R-2026-65, a Resolution of the City Council of the City of Placentia, California, authorizing a budget amendment in Fiscal Year 2026-27 in compliance with the City Charter of the City of Placentia §§ 1206 and §§ 1209 pertaining to appropriations for actual expenditures; and
2. Approve Amendment No. 1 to Public Works Agreement with Vincor Construction, Inc for an additional $20,357.59, with a cumulative not-to-exceed amount of $142,246.93; and 
3. Authorize the Acting City Administrator and/or her designee to approve contract change orders up to ten percent (10%) of the Amendment No. 1 amount, or $2,035.76; and
4. Authorize the Acting City Administrator and/or her designee to execute all necessary documents, in a form approved by the City Attorney.

The item conforms to Strategic Plan Goal No. 3, Maintain and enhance streets, parks, and public facilities to ensure they are well-appointed, clean, attractive, and reflective of the City’s commitment to quality.

On July 21, 2026, the City Council approved awarding a construction contract to Vincor Construction, Inc for $121,889.34 for Aguirre Building Renovation Project which included replacing the countertop, sink, and flooring in the rental building to enhance functionality and aesthetics. The project team encountered unanticipated high humidity levels during moisture testing and unforeseen mold during the demolition work including areas of water damage. The work to address the mold included a mold survey, mold clearance, mold abatement and additional drywall patch repairs. 

As noted in the previously approved staff report dated July 21, 2026, staff understood sufficient project funding was available to cover the cost of this additional work. To avoid allowing the mold to remain for an extended period and potentially create a public health hazard, the City Administrator authorized the additional work necessary to address the mold issue. Staff directed the contractor to proceed with the mold abatement and any repairs necessary. Completion of this work abated the mold and maintained a clean, safe and suitable building for continued public use. 

Staff recommends the approval of Amendment No. 1 in the amount of $20,357.59 to the subject agreement for construction services related to the Aguirre Building Renovation Project. This amount includes the original 10% construction contingency amount of $12,188.93, and an additional $8,168.66 based on the unforeseen conditions encountered during construction. As a result of this additional work, construction costs are expected to go beyond the previously approved agreement's $134,078.27 not-to-exceed amount by $8,168.66 for a new total construction contract not-to-exceed amount of $142,246.93. Additionally, this item also recommends the approval of Resolution No. R-2026-65, which will make $10,204.44 available in the project account to cover the additional expense.

The total construction cost for the Aguirre Building Renovation Project amounts to $142,246.93, including the additional work proposed to be authorized under Amendment No. 1. The project has $134,078.27 in previously budgeted funds. Additional funding will be obtained through Resolution No. R-2026-65, by transferring $10,204.44 from the Parks and Recreation Development Impact Fee fund balance.
