Introduction
May 2025 marked the successful transition from subgrade infrastructure to the completion of major structural foundation scopes at the Foster City Recreation Center Project. The construction team completed extensive concrete placements across the building footprint, pile caps, and grade beams. These activities complemented the earlier elevator pit and vault placements and were followed immediately by formwork removal, waterproofing application, and rebar installation in preparation for vertical framing. Progress continued in parallel across scopes such as layout and formwork for new bocce courts, bioretention grading, fire water underground, and storm drain backfill. PG&E finalized temporary power activation, while coordination with AT&T continued. Offsite fabrication for structural steel advanced to maintain schedule alignment. With all primary foundation work complete and inspections passed; the project remains on its critical path entering June.

Construction Activities Completed May 2025
Foundation and Underground Work:
• Concrete placement completed at elevator pit and electrical vault. • Formwork stripping and foundation cleaning were completed for the following pour. • The installation of rebar, edge forms, and slab dowels for suspended slab areas has progressed. • Waterproofing of vault and slab edges performed.
• Suspended slab gravel base, and drainage mat preparation continued west and east.
Site Utilities and Infrastructure:
• Backfill of electrical vault using approved CLSM completed. • Trenching and pipe installation for storm drains and bioretention progressed in the Southeast lot and the bocce court area.
• Fire water trenching staged, pipe delivery in progress; traffic control plans coordinated. • CCTV of 54" storm drain line documentation submitted. • Irrigation conduit rerouting in Rose Garden coordinated with Parks.
Electrical and Power Coordination:
• Site conduit rough-in at slab areas for lighting and power completed. • Temporary power infrastructure activated by PG&E after panel adjustments. • AT&T redline review initiated; routing revisions underway.
Testing, Inspection & Coordination:
• Apex conducted field sampling and observation for vault and elevator slab concrete. • Romig completed site compaction and bioretention excavation observation. • Correction Notice 001 was resolved following the design engineer's comments to the Building Official.
• Coordination meetings held for LEED documentation and weekly submittal review. • Concrete mockups, waterproofing submittals, and lighting base rebar approvals are underway.
Construction Activities Planned for June 2025
Foundation and Structural Work:
• Finalize edge formwork and slab prep at Events and Community Wings. • Place west and east structural slab concrete.
• Begin vertical structural steel erection following slab cure and anchor survey • Helical piles deferred submittal approval.
Utility and Infrastructure Work:
• Continue fire water and domestic water installation and testing. • Finalize layout for site storm drain risers and tie-ins. • Continue rough grading and tree protection measures in the landscape areas.
Site Improvements and Mock-Ups:
• Install and review site concrete color/finish mockups. • Place and review the seat wall and flatwork concrete at the bocce courts. • Confirm elevations and anchor details for shade structures.
Submittals and Procurement:

GRIFFIN STRUCTURES
• Structural steel, mechanical rooftop units, curtain wall, storefront, and waterproofing procurement tracking.
• Ongoing elevator product data coordination and management. • Resubmit the LEED action plan and schedule update.
Key Challenges
• LEED and Mock-Up Scheduling: Tracking long lead submittals and action plan revisions for LEED. • Telecom Coordination: AT&T and Comcast trench layouts require adjustment due to conflict with the driveway apron and existing utilities.
• Timely submittal and RFIs from the contractor and their review by the design team. • Change orders due to design coordination and revisions.
Budget Updates
The following Change Order Requests were approved by the City in May 2025 and included in approved Contract Change Order #4 (Total Amount $45,907.00).
• COR #16 – Grease Waste Heat Trace Insulation: $32,000 Negotiated amount agreed to by all parties. This COR covers insulation for heat trace wire for grease waste piping.
• COR #22 – Electrical Support Waterproofing: $12,978
Approved by the City. Adds waterproofing for electrical support hardware per RFI 124. • COR #24 – Added mop sinks at janitor closets: $8,979

Summary
May 2025 represented the culmination of the project’s foundation phase and a key advancement toward vertical construction. Full building foundation placement was completed, encompassing not only the elevator pit and electrical vault but also grade beams and pile cap connections. Inspection approvals were secured for rebar, grease waste piping, floor drains, and conduit systems below the slab. Vault waterproofing, slab edge formwork, and CLSM backfill were all finalized.
On-site coordination also addressed AT&T routing, temporary power activation, and layout adjustments for light pole conduits and bioretention areas. Submittals and mockups progressed to support the procurement of long-lead items, including structural steel and curtain wall systems. The City’s Building Inspector and third-party consultants confirmed compliance at multiple milestones.
With subgrade scopes concluded, the project enters June prepared for steel erection, utility tie-ins, and early MEP infrastructure.
Note: This report is a monthly update for the Foster City Recreation Center Rebuild Project, highlighting key construction activities, upcoming tasks, challenges, and budgetary considerations.
