The Challenge

A critical government complex in San Juan required comprehensive renovation and seismic retrofitting across three interconnected buildings. The project scope included structural reinforcement, MEP system upgrades, and modernization while maintaining operations in portions of the facility.

Project Complexity:

  • Multi-Building Coordination: Three structures (1950s, 1970s, 1990s) with different construction methods and conditions
  • Seismic Code Compliance: Full seismic retrofit to meet current IBC and Puerto Rico Building Code requirements
  • Occupied Facility: Phased construction to maintain government operations with minimal disruption
  • Hurricane Resilience: Enhanced structural systems and building envelope for Category 4 hurricane resistance
  • Historical Considerations: Main building listed on National Register—preservation requirements added complexity

What Expert Analysis Revealed

Structural Deficiencies

Comprehensive structural review identified unreinforced masonry walls, inadequate lateral bracing, and deteriorated concrete elements requiring immediate attention.

Impact: $2.8M in additional structural reinforcement beyond original scope

MEP System Coordination

Analysis revealed conflicts between new seismic bracing and existing mechanical, electrical, and plumbing systems across all three buildings. Detailed coordination prevented costly field changes.

Impact: 120+ system conflicts resolved during preconstruction—avoiding $1.5M in change orders

Phasing Logistics

Expert scheduling analysis determined optimal construction sequence to maintain operations while meeting aggressive deadlines for federal funding requirements.

Impact: 8-phase plan developed to maintain 70% building occupancy throughout construction

Results

Comprehensive Accuracy

Multi-discipline analysis across structural, architectural, and MEP systems resulted in 97% estimate accuracy—critical for public sector budget compliance.

Risk Mitigation

Early identification of structural deficiencies and system conflicts prevented mid-construction delays and budget overruns common in renovation projects.

Timeline Adherence

Detailed phasing plan enabled project completion within federal funding deadlines while maintaining continuous government operations.

Code Compliance

Seismic retrofit meets current IBC standards and Puerto Rico Building Code requirements—ensuring facility resilience for decades to come.

Total Value Delivered
$4.3M+ in Cost Avoidance

Through comprehensive preconstruction analysis, the project avoided major change orders and schedule delays that typically plague complex government renovations.

Key Takeaways

  • Multi-building projects require specialized coordination—different construction eras and methods demand tailored analysis approaches
  • Seismic retrofits have cascading impacts—new bracing affects MEP systems, ceiling heights, and architectural finishes
  • Occupied renovation demands detailed phasing—operational continuity planning must start during estimation, not construction
  • Government projects need budget certainty—accurate estimates are critical for funding compliance and public accountability
