Schedule and Critical Path Status Schedule Update #13 reflects continued progression through exterior enclosure and interior rough-in activities, with overall sequencing and logic generally consistent with the prior update. The critical path remains focused on achieving and maintaining full building dry-in, followed by completion of interior framing, overhead MEP rough-ins, and downstream inspection, testing, and commissioning activities. Exterior enclosure work, including roofing, flashing, waterproofing, and window installation, continues to be the primary near-term driver of schedule performance. These activities remain closely coordinated with interior work, as completion of dry-in directly supports acceleration of wall close-in, soffit framing, and ceiling installation. Weather sensitivity and sequencing between envelope trades continue to require active management. Interior construction has progressed in parallel where enclosure conditions allow, with framing, masonry, and MEP rough-ins advancing by area. Coordination across trades in larger program spaces remains a key focus to maintain productivity and avoid downstream conflicts as work transitions toward finishes. Schedule Update #13 does not identify a shift to the contractual completion milestones. Overall schedule risk remains concentrated in weather-dependent enclosure activities, coordination-intensive interior spaces, and timely resolution of deferred submittals and delegated design items. The project team continues to manage these risks through detailed look-ahead planning, phased installation strategies, and ongoing coordination with the contractor, design team, and City. Inspection & Quality Control Inspection and quality control activities in December remained active and well-coordinated as construction advanced through enclosure and interior build-out. Special inspections performed by Apex Testing Laboratories included field welding, reinforcing steel, masonry, metal decking, and related structural work. All inspected work was found to comply with approved drawings, specifications, and installation requirements, and no non-conformance reports were issued. In parallel, routine Building Department inspections were conducted throughout the month across buildings, mechanical, electrical, plumbing, gypsum board, and rough construction disciplines. Inspections were completed incrementally by area and system, with partial approvals issued where appropriate to support continued progress. No unresolved inspection issues were identified, and coordination with the Building Department continues to support ongoing construction activities. Construction Activities Completed This Month Construction activities in December focused on advancing exterior enclosure, interior build-out, and structural completion items as weather permitted. Exterior work included continued progress on standing seam roofing, low-roof waterproofing, flashing, and penetration detailing. Coordination of envelope interfaces progressed in preparation for aluminum window installation and full dry-in sequencing. Masonry advanced at the trash enclosure. Interior work continued in parallel, including framing, overhead mechanical, electrical, and plumbing rough-ins, and preparation for soffit and ceiling work.

placement were completed in designated areas and verified through special inspection. Quality control activities were ongoing throughout the month, with field welding, reinforcing steel, masonry, and roofing-related inspections completed and accepted. No non-conforming work was identified during December. Construction Activities Planned Next Month January work will continue to prioritize enclosure progress and interior system advancement to support increased interior productivity. Planned exterior activities include continued standing seam roofing, low-roof waterproofing, flashing, and the start of aluminum window installation as weather conditions allow. Envelope coordination will remain a focus to support sustained dry-in progress. Interior work will continue with framing completion, masonry close-out, and expanded mechanical, electrical, and plumbing rough-in activities. Coordination of soffits, ceilings, and device layouts will advance in larger program spaces to support downstream inspections and finishes. Additional planned activities include ongoing inspections and testing, continued utility coordination in support of permanent power readiness, and preparation for upcoming interior close-in and commissioning activities. Key Challenges Weather-Sensitive Enclosure Work: Roofing, waterproofing, and window installation remain sensitive towinter weather conditions and require close sequencing to maintain progress. Envelope and Interior Coordination: Continued integration of flashing, penetrations, and envelope details requires active coordination across trades to avoid rework. Deferred Submittals and Delegated Design: Timely resolution of remaining deferred submittals remains important to maintain downstream production and commissioning timelines. Contract and Contingency Financial Overview Original Contract Amount $44,626,000.00 Contingency (10%) $4,462,600.00 Approved Contract Change Orders $769,805.00 Total Adjusted Contract Amount $45,395,805.00 Contingency Remaining $3,692,795.00 Contingency % Remaining 82.7% Total Completed and Stored to Date $25,816,515.65 % of Contracts Billed to Date 56.9% FOSTER CITY COMMUNITY CENTER REBUILD PROJECTCONSTRUCTION MANAGEMENT MONTHLY REPORT (CIP 301-678)

Contract Change Order Updates The project continues to maintain a strong contingency position as the team advances through enclosure and interior coordination activities. Pending Contract Change Order #10 aggregates multiple previously reviewed and City-approved CORs, primarily related to unforeseen conditions, roofing and envelope coordination, and minor interior code conflicts. These items reflect necessary design clarifications and field coordination typical of this project phase and do not represent scope expansion. The items included are summarized as follows: COR #9: Unforeseen concrete encasement abatement encountered during demolition (RFI 45). COR #12: Electrical Yard Fence and Gate Revisions (Bulletin 2). COR #20: Concrete Masonry Unit walls at Ceramics Yard (RFI 85). COR #52.2 / #54.1: Added tapered and flat insulation at high roof areas to resolve elevation and drainage transitions (RFIs 250.1, 266). COR #57: Added framing and flashing at low roof penetrations to maintain waterproofing continuity (RFI 269). COR #61: Curb notching at recessed paper towel dispensers to meet code-required mounting heights (RFI 286). COR #66: Gap correction between exterior sheathing and slab-on-grade conditions (RFI 312). COR #70: Vent piping flexible connections to accommodate movement and alignment (RFI 255.1). COR #71.1: Trash enclosure hose bib installation clarification (RFI 283). COR #72: Roof hose bib clarification at HB-3 (RFIs 43/146). COR #73: Restroom Piping Revisions (Facilities) COR #79: Food Service Equipment (Specification Update) All CORs included in CCO #10 carry zero-time extension and are aligned with maintaining enclosure progress and interior completion sequencing. As presented, CCO #10 would total $132,677.00. Financial and Project Risk Status Overall project risk remains moderate and manageable. Schedule risk continues to be concentrated around weather-sensitive enclosure activities, coordination-intensive interior work, and the timely resolution of deferred submittals as the project advances through the enclosure and interior build-out phase. Financial risk remains well controlled, with a strong construction contingency position relative to this stage of work. Even with the anticipated execution of CCO #10, contingency usage reflects normal design resolution and coordination-driven adjustments rather than systemic cost risk. Remaining contingency provides sufficient coverage for downstream uncertainties associated with final envelope integration, long-lead items, and commissioning activities. In addition to executed and pending change orders, the project continues to track several CORs under review for potential inclusion in future change orders. These items are in varying stages of design clarification, pricing validation, and owner coordination. The majority reflect normal refinement as construction transitions from documentation to installation, where final detailing and field coordination are confirmed.
