Location: 22512 SR 410 E, Bonney Lake, WA 98391
Scope: MEP Engineering, Washington State Energy Compliance Report
Project Type: Winery | New Construction | Hospitality & Industrial
Client: Oleg Seletskyy | Architect: ORC-A Design
Building Area: ~16,000 sq. ft.
Project Overview
Seletskyy Winery is a newly constructed 16,000-square-foot facility in Bonney Lake, Washington, featuring a wine storage warehouse, tasting room, full-service restaurant, and rooftop bar. Originally envisioned as a simple warehouse, the design evolved into a bold architectural statement, characterized by dramatic rooflines, cantilevered forms, and a prominent overhang that defines the building’s arrival experience.
Our team was selected to provide comprehensive MEP (Mechanical, Electrical, and Plumbing) engineering services along with a detailed Washington State Energy Code Compliance Report to support building permitting and construction documentation.
Challenges & Design Coordination
One of the primary challenges was managing effective communication between our engineering team—based in the United States—and the international owner. Despite initial concerns about remote coordination, we worked closely with both the client and the architect to establish a responsive and transparent workflow. This collaborative approach enabled us to deliver technical documents with exceptional speed and clarity.
From the outset, the architectural vision demanded precise coordination across disciplines. The structure’s wood-framed primary system, combined with selective steel framing to support long spans and dramatic cantilevers, required thoughtful MEP routing that preserved design intent without compromising performance or compliance.
Technical Highlights
- Mechanical Design: HVAC strategies were developed for diverse programmatic zones—including the double-height wine storage warehouse, dining areas, kitchen, and rooftop bar. Ventilation systems were designed to meet occupancy-specific air change requirements while maintaining thermal comfort across multiple levels.
- Electrical Design: Power distribution was engineered to support both hospitality and industrial operations. Energy-efficient lighting systems were specified throughout, including recessed LED fixtures, track lighting, and exterior-grade luminaires for the rooftop terrace and entrance canopy. Exit signage and emergency egress lighting were coordinated in compliance with IBC and local codes.
- Plumbing Systems: Plumbing design incorporated multiple restroom groups, kitchen fixtures, janitorial stations, and service sinks, designed to handle mixed-use occupancy with varying peak loads.
- Energy Compliance: A full WSEC (Washington State Energy Code) energy report was prepared, documenting envelope, lighting, and HVAC system performance to ensure permit approval.
- Integration with Architecture: MEP systems were embedded within a complex structure of open ceilings, exposed finishes, and multi-level zones. System routing avoided conflicts with exposed wood framing and steel beams, especially in the cantilevered roof and bar areas.
Outcomes
Thanks to efficient coordination and responsive design practices, the MEP and energy scope for Seletskyy Winery was completed on an accelerated timeline. The project achieved full permit submission with MEP documents supporting all critical mechanical, electrical, and plumbing functions while maintaining architectural integrity.
This project illustrates our team’s capability to deliver high-performance building systems for architecturally ambitious designs. Seletskyy Winery is now positioned to become a regional destination—merging production, hospitality, and visual impact into a single cohesive facility.
