Engineering in Bellevue

Services in Bellevue

MEP engineering

• High-rise MEP for 40+ story residential and office towers: stacked risers, booster pumps, smoke control, and emergency power
• Tech-tenant TI work with dense cooling loads, supplemental HVAC, and redundant power for cloud and trading operations
• Washington State Energy Code plus Bellevue's green-building expectations driving heat-recovery, DOAS, and all-electric systems
• SDC D seismic bracing and flexible couplings for MEP risers in tall buildings
• Luxury multifamily amenity systems: central plants, snow-melt, and high-end plumbing and ventilation
• Data-room and edge-computing support inside office and mixed-use podiums

Structural engineering

• High-rise seismic design in SDC D, with performance-based design common for towers over 240 feet
• Deep excavations and shoring for multi-level below-grade parking in downtown's dense core
• Mercer Slough and Kelsey Creek wetland-adjacent sites with soft soils requiring deep foundations
• Transfer structures and podium slabs for mixed-use towers over retail bases
• Glacial till bearing soils on the plateau, with perched groundwater complicating excavations
• Light-rail (2 Line) adjacency: vibration and settlement review for towers near the alignment

Civil engineering

• Bellevue stormwater code and the city's exacting development standards, with flow control for the Lake Washington and Lake Sammamish basins
• Wetland and stream buffers (Mercer Slough, Coal Creek) with critical-areas review
• Steep-slope grading on the hillsides above the lake in Medina, Clyde Hill, and Somerset
• Downtown right-of-way coordination with Sound Transit 2 Line operations
• Phosphorus-sensitive Lake Sammamish basin treatment requirements
• Traffic and frontage improvements under Bellevue's transportation development standards

Electrical engineering

• Emergency and standby power per NEC Articles 700/701/702: generator sizing, automatic transfer switch configurations, and life-safety versus optional-standby branching for Bellevue luxury multifamily.
• Engides quotes electrical engineering fast and prices it sharp — PE-stamped drawings backed by Apex Grid Engineering's licensed PEs, without the big-firm markup Bellevue owners expect.
• We design Bellevue luxury multifamily lighting for both the energy code and the occupants — ASHRAE 90.1-compliant controls, glare-controlled layouts, and panel schedules the electrician can actually build from.
• Grounding, bonding, and surge protection engineered for Washington's conditions — Bellevue transit-oriented development need power quality that holds up, and our drawings spell out every electrode and bond.
• Puget Sound Energy or Seattle City Light service rules shape every Bellevue project: we confirm service voltage, metering, and utility-side requirements before drawings go to the Bellevue building department, not after the first correction cycle.

Plumbing engineering

• Bellevue high-rise residential towers need water systems sized for peak demand, not averages — we calculate fixture units, size mains and branches, and coordinate meter and backflow locations with the civil drawings.
• The fastest Bellevue, WA plumbing permits come from complete riser diagrams: our isometrics show every vent, trap, and cleanout so the Bellevue building department reviewers don't have to guess.
• One point of contact, one coordinated set: Bellevue, WA tech office and headquarters ti owners get plumbing drawings that match the architectural backgrounds and pass the Bellevue building department review.
• Sanitary and storm drainage engineered for Bellevue's conditions: proper slopes, cleanout placement, and grease/interceptor strategy for food-service tenants inside tech office and headquarters ti projects.
• In Bellevue's a marine climate with wet winters, exterior hose bibbs, irrigation backflow assemblies, and rooftop piping get freeze-rated details — the callbacks we prevent never make it onto a punch list.

HVAC engineering

• Heating and cooling load calculations for Bellevue high-rise residential towers using a marine climate with wet winters design conditions — envelope, occupancy, and ventilation loads modeled so equipment is sized right, not oversized by habit.
• Ventilation for Bellevue transit-oriented development projects is designed for the actual occupancy — conference-heavy floors, kitchens, and locker rooms each get their own air-change logic, not one blanket rate.
• Energy modeling and Title-24-style documentation for Bellevue high-rise residential towers: our compliance forms match the drawings, so the Bellevue building department energy review doesn't generate a second correction cycle.
• Bellevue, WA contractors call Engides when the schedule is tight: fast mechanical quotes, coordinated drawings, and a PE stamp the Bellevue building department accepts.
• Our Bellevue duct designs coordinate above the ceiling before construction starts — transit-oriented development projects can't afford the field reroutes that come from uncoordinated shop drawings.
