Report Period: August 1 – 31, 2025
General Contractor: BHM Construction LLC
Construction Manager: Griffin Structures
Architect of Record: Group 4 Architecture
Introduction
August marked a pivotal month for the project as structural steel activities neared completion and the focus shifted toward enclosure and infrastructure systems. The construction team continued metal decking installations at both roof and second-floor levels and progressed with trenching and utility infrastructure throughout the site.
Interior preparation also advanced, including restroom plumbing rough-in and layout for mechanical, electrical, and plumbing (MEP) overhead work. Off-site improvements, including asphalt paving, signal pole installation, and sidewalk/curb work, were substantially completed, closing out much of the right-of-way work initiated earlier in the summer.
While substantial progress was made, several key dependencies emerged during this reporting period.
Coordination overlays for overhead MEP systems and unresolved deferred submittals now present potential impacts to critical path activities. Maintaining momentum into September will require the timely resolution of these items, effective dry-in sequencing, and continued inspection support for enclosure and infrastructure scopes.

Schedule and Critical Path Status
• Schedule Update #9, Submitted 8/15/25, continues to project Substantial Completion in early June 2026, maintaining approximately two weeks of float relative to the contractual milestone of June 17, 2026.
• The critical path remains through completion of structural steel framing, roof decking, and dry-in preparation activities. August focused on:
o Roof and low roof decking.
o Installation of miscellaneous steel, stairs, and base plates o Begin layout of MEP hanger and equipment pad penetrations • Coordination of roof blocking, fireproofing, and MEP overhead rough-in is now emerging as the next major driver of schedule.
• Near-critical scopes include:
o MEP coordination overlays (pending finalization) and release of hanger/shop drawing layouts o PG&E Service Yard trenching and utility vault coordination (resubmittal required) o Shell Blvd. utility trenching and inspections (ongoing through September) o Curtain wall and rainscreen deferred submittals, still under review • Off-site signal modification work was completed in August and is no longer a driving path.
Inspection & Quality Control
Structural Steel Oversight continued as a priority focus:
• Apex Testing Labs conducted daily high-strength bolting and field welding inspections, confirming completion of all critical beam and brace connections.
• Ultrasonic Testing (UT) was performed on full penetration welds with no recordable discontinuities. • Degenkolb Structural Observation #6 verified steel framing and BRB installation in general conformance. Outstanding items, such as missing gusset plate bolts and welds, were directed to be completed, and decking attachment photos were requested for the record. This issue was resolved via RFI and follow-up inspection.
Concrete and Grouting activities were verified across multiple scopes:
• Column baseplate grouting was completed; samples taken for compressive testing showed proper installation.
• Apex performed inspections on slab-on-grade curbs, play area footings, and site concrete elements, including pull testing of rebar dowels, which passed required thresholds.
Trenching, Duct banks, and Utility Backfill were heavily inspected:
• Romig and Apex inspected and approved concrete encasements for fiber/telecom duct banks, light

pole base trenching, and fire water piping. Conduits for EV chargers and site lighting were confirmed in place.
• All trench scopes along the east and south wings were backfilled following successful compaction and encasement inspections.
Plumbing and MEP Rough-in began:
• City inspections verified toilet carrier installations and vent risers in all restroom cores. • MEP hanger layout and sleeve penetrations began in coordination with deck dry-in activities and will continue into September.
Off-Site Improvements continued:
• Final City inspections were completed for asphalt paving at Shell Blvd and Foster Square Lane, ADA- compliant curb ramps, and signal pole installation. Sidewalk concrete was placed and accepted under City observation.
Across all scopes, inspections were completed with no major deficiencies reported. Coordination between BHM, Romig, Apex, and the City was effective in keeping work on track and verified in the field.

• Framing and Interior Prep:
o Begin layout and erection of light-gauge framing for interior walls, particularly in the Recreation Wing.
o Coordinate submittals and layout for storefront systems, including in-place mockups. o Continue layout for permanent fencing, play area structures, and signage footing locations. • Envelope Systems and Submittal Closeout:
o Progress review and final approval of deferred submittals related to curtain wall, storefront, rainscreen, fire alarm, generator, and elevator scopes. o Prepare for rough framing inspections and weather protection milestones by late September.
• Inspection and Testing:
o Continue scheduled welding, bolting, fireproofing, and concrete inspections. o Conduct utility inspections for lighting, fire water, and telecom as trench scopes are completed.
o Maintain coordination with inspection agencies for daily structural, sitework, and MEP observations.
Key Challenges
• Overhead MEP Coordination Delay: Final coordination overlay drawings for mechanical, electrical, and plumbing systems remain outstanding, delaying layout of hangers, sleeves, and equipment penetrations. This has created pressure on the dry-in sequence and subsequent enclosure milestones.
• Deferred Submittal Approvals: Multiple deferred items, including the curtain wall, generator, fire alarm, seismic bracing, and elevator, remain under review or require resubmission. Delays in these approvals may impact long-lead procurement and rough-in sequencing if not resolved early in the next period.
• Utility Coordination in Public Right-of-Way: Sanitary sewer and fire water, through Shell Blvd., continue to require tight coordination with inspection agencies and adjacent entities. Concrete encasement, backfill, and trench closure approvals must be obtained in a narrow window to avoid schedule impacts.
• Dry-In Preparation and Roofing Access: Sequencing for roofing prep, blocking, and vapor barrier installation is complicated by incomplete roof penetrations and pending layout coordination for mechanical systems. This poses a risk to maintaining weather protection timelines going into fall. • Site Infrastructure and Exterior Mockups: Fencing, play area structures, and signage elements are awaiting final design decisions. Delays in finalizing these scopes could result in rework or inefficient mobilization later in construction.

Summary
The project made visible progress throughout August, with structural framing nearing full completion and preparation for building enclosures now underway. Milestones included installation of metal decking, baseplate grouting, and completion of utility trenching and encasement in key site zones. Off-site work, including paving and signal modifications, was also substantially completed and inspected.
Inspection activity remained high across structural, site, and utility scopes, with reports indicating general conformance and no major deficiencies. Coordination between the field team, design consultants, and inspectors was effective in verifying work in place and clearing scopes for follow-on trades.
However, several challenges remain unresolved. Overhead MEP coordination overlays have not yet been finalized, delaying layout and hangers in critical areas. Several deferred submittals, most notably for curtain wall, generator, and elevator systems, remain pending, potentially impacting procurement and rough-in schedules.
Looking ahead, the project’s success in September will depend on the timely resolution of outstanding coordination items and the ability to maintain momentum across multiple fronts. With steel framing activities wrapping up, the focus will shift to closing out early infrastructure, initiating building enclosure, and setting the stage for interior build-out.
