body
BACKGROUND INFORMATION:
This project provided specialized structural concrete remediation at the Hutchins Street Square Pool (Pool), utilizing pressure epoxy injection to restore the monolithic integrity of the concrete shell and mitigate hydrostatic leakage.
The City obtained reports from Siegfried Engineering, Inc. (SEI) and Pacific Coast Leak Detection (PCL), which ultimately identified active seepage through the deep-end concrete shell. The Technical assessments specifically revealed:
• Sub-Structural Fractures: Multiple stress fractures exist within the gunite substrate, likely obscured by the existing fiberglass overlay.
• Permeation Pathways: Hydrostatic pressure is forcing water through compromised pipe penetrations or voids, leading to localized spalling and oxidation of the reinforcing steel (rebar).
• Acoustic Analysis: Hydrophone testing by PCL confirmed that while the structural fractures are significant enough for water migration, they remain subsurface and require targeted injection rather than simple topical sealing.
This project’s remediation served as a medium-term structural solution (estimated up to 5-year service life) until a comprehensive remodel and plaster resurfacing can be phased into the Capital Improvement Plan.
On May 6, 2026 the City Council adopted a resolution (2026-092) authorizing the City Manager to award the contract to the lowest responsive bidder and execute change orders in a combined amount not-to-exceed $40,000 and appropriate funds in the amount of $40,000.
On May 27, 2026 the bid opening was held and the City received (1) bid from Ichor Restoration, from Prunedale, CA, in the amount of $29,900.
On July 28, 2026, the contract was executed and notice to proceed was sent out.
All work was completed in substantial conformance with the plans and specifications approved by City Council. The final contract price was $38,380 including (1) change order totaling $8,470.
Change order No. 1 ($8,470) covers extra work required to remove and expose additional concrete spalling areas that were more extensive than originally anticipated. It also includes additional linear footage of cracks that were discovered after the original investigation that were epoxy-injected.
See Exhibit A for project photos.
Following acceptance by the City Council, as required by law, the City Engineer will file a Notice of Completion with the County Recorder’s office. The notice serves to notify vendors and subcontractors that the project is complete and begins their 30-day period to file a stop notice requiring the City to withhold payments from the prime contractor in the event of a payment dispute.
FISCAL IMPACT:
The project will have a minimal impact on annual maintenance costs, however it will reduce the City’s exposure to claims related to the deterioration of the pool’s concrete shell.
FUNDING AVAILABLE:
This project was funded through a restricted donation by the Hutchins Street Square Foundation.
