Engineering in Bothell

Services in Bothell

MEP engineering

• Washington State Energy Code compliance — plus Bothell's own energy code, stricter still — driving high-performance envelopes, heat-recovery ventilation, and all-electric designs
• Seismic bracing and anchorage of MEP systems per ASCE 7 Chapter 13 for Seismic Design Category D, critical for hospitals, labs, and high-rise residential
• Electrification mandates phasing out fossil-fuel heating in new commercial construction, pushing heat-pump and VRF system design
• Data-center and lab demand from the tech sector: high-density cooling, redundant power, and generator/UPS coordination
• Corrosive marine air on Elliott Bay-adjacent sites influencing equipment selection and exterior MEP detailing
• Existing-building retrofits in Pioneer Square and downtown towers, fitting modern ventilation and energy targets into century-old structures

Structural engineering

• Seismic Design Category D design for the Cascadia subduction-zone threat, with special moment frames, shear walls, and foundation detailing for major events
• Liquefaction-prone fill soils in SODO, Interbay, and the waterfront requiring deep foundations, ground improvement, or mat slabs
• Steep-slope sites on Queen Anne, Capitol Hill, and West Bothell demanding shoring, tiebacks, and hillside foundation engineering
• Mass timber construction — Bothell is a national leader — with CLT floor systems, hybrid steel-timber frames, and fire-rated detailing
• High-rise residential and office towers in South Lake Union and Denny Triangle with performance-based seismic design
• Seismic retrofit of unreinforced masonry buildings, an ongoing citywide priority

Civil engineering

• Stormwater design under the City of Bothell Stormwater Code and the WA Ecology manual, with flow control for discharges to Lake Union, Lake Washington, and Puget Sound
• Combined sewer overflow (CSO) constraints in older neighborhoods, pushing on-site detention and green stormwater infrastructure
• Duwamish Waterway Superfund adjacency: contaminated-soil handling and strict dewatering discharge requirements on industrial sites
• Steep-slope and landslide-prone area grading under Bothell's Environmentally Critical Areas code
• SDOT street-improvement and right-of-way permitting for downtown and South Lake Union projects
• Shoreline permitting along Elliott Bay, Lake Washington, and the Ship Canal

Electrical engineering

• Power distribution across a Bothell waterfront and maritime industrial means transformer sizing, voltage drop on long feeders, and selective coordination of overcurrent devices — the details that keep a Washington facility running instead of tripping offline.
• Lighting layouts and controls for Bothell waterfront and maritime industrial engineered to ASHRAE 90.1: photometric plans, daylighting zones, and occupancy/vacancy controls that pass Washington's energy review without post-permit value engineering.
• Send us the floor plans and load list; Bothell, WA projects get a firm electrical quote back quickly and permit-ready drawings sealed by a Washington-licensed PE.
• Bothell City Light service rules shape every Bothell project: we confirm service voltage, metering, and utility-side requirements before drawings go to the Bothell Department of Construction and Inspections, not after the first correction cycle.
• Grounding, bonding, and surge protection engineered for Washington's conditions — Bothell hospital and healthcare expansions need power quality that holds up, and our drawings spell out every electrode and bond.

Plumbing engineering

• the Bothell Department of Construction and Inspections plumbing review in Bothell, WA keys on isometrics, fixture-unit math, and gas sizing — our Bothell sets include all three, drawn cleanly enough that corrections stay minor.
• Water-efficient fixture selection for Bothell mass-timber mixed-use that still passes plan check: 1.28 gpf water closets, metered faucets, and the calculations the Bothell Department of Construction and Inspections wants to see in the submittal.
• One point of contact, one coordinated set: Bothell, WA waterfront and maritime industrial owners get plumbing drawings that match the architectural backgrounds and pass the Bothell Department of Construction and Inspections review.
• Bothell mass-timber mixed-use 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.
• Bothell mass-timber mixed-use with process loads get engineered details, not catalog cuts — interceptors, separators, and specialty drainage drawn to the Washington plumbing code.

HVAC engineering

• Bothell, WA contractors call Engides when the schedule is tight: fast mechanical quotes, coordinated drawings, and a PE stamp the Bothell Department of Construction and Inspections accepts.
• Controls sequences written for the Bothell operator, not just the submittal: economizer changeover, morning warm-up, and unoccupied setback logic that actually gets programmed.
• Energy modeling and Title-24-style documentation for Bothell tech office campuses and tenant improvements: our compliance forms match the drawings, so the Bothell Department of Construction and Inspections energy review doesn't generate a second correction cycle.
• Heating and cooling load calculations for Bothell tech office campuses and tenant improvements 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 Bothell life-science and research labs 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.
