Adaptive Reuse & Expansion Engineering for Iglesia Church – Bremerton, WA
S3DA Design provided MEP engineering services for the Iglesia Church Project, an adaptive reuse and expansion of an existing 1979-era facility in Bremerton, Washington. A key project objective was maintaining the existing 2,995-square-foot building footprint and occupant load of 299 persons while modernizing building systems and meeting current code requirements.
S3DA’s Scope
Mechanical Engineering
- New multi-split heat pump HVAC system
- Interior blower units and air distribution design
- Energy Recovery Ventilator (ERV) system with distributed ductwork
- HVAC load calculations and equipment coordination
Electrical Engineering
- Complete LED lighting retrofit
- Power distribution coordination for new HVAC equipment
- Life safety notification upgrades, including horn/strobe systems
- Electrical system modifications for renovated and expanded areas
Plumbing Engineering
- Existing restroom renovation
- New restroom facility design
- New sanitary sewer connection on the north side of the building
- Plumbing fixture and piping coordination
Key Challenges & Solutions
One of the project’s primary challenges was integrating modern building systems within an existing structure while preserving critical code thresholds related to building area and occupant load. S3DA’s coordinated MEP design approach optimized system layouts, improved energy performance, and supported compliance with the 2021 International Building Code (IBC) and Washington State Energy Code (WSEC).
The Result
The Iglesia Church Project transforms an aging facility into a modern, energy-efficient community space with improved occupant comfort, upgraded life-safety systems, and enhanced functionality. Through integrated engineering coordination, S3DA delivered a permit-ready design package that supports the church’s long-term operational and ministry goals.
