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.
