Let's work together
Washington PEMB Builders
Pre-engineered metal building construction is more demanding than it looks. A successful PEMB project requires precise structural engineering, manufacturer coordination, code-compliant design for wind, snow, and seismic loads, and the field experience to erect a steel building system efficiently and safely — without costly change orders.
SEA CON has the experience, the manufacturer relationships, and the licensed personnel to manage every phase of your PEMB construction project. We work directly with owners, developers, and businesses across Washington to deliver buildings that go up on schedule, perform operationally from day one, and hold their value for decades.
Whether you’re building your first pre-engineered metal building or expanding an existing facility, SEA CON is built for this.
Full-service PEMB construction from site evaluation through final turnover.
Our PEMB Construction Services
SEA CON provides comprehensive general contracting and construction management services for pre-engineered metal buildings of every size and configuration. Our team manages the entire project — coordinating design, manufacturers, permitting agencies, and specialty subcontractors — so you can focus on your business.
Design & Drafting
Custom design and engineering drawings tailored to your clear-span, eave height, and load requirements — developed before fabrication begins so there are no surprises mid-project.
Manufacturer Coordination & Sourcing
As a top-ranked PEMB dealer, we work directly with leading steel building manufacturers to source the right system and components for your project, and manage that relationship from order to delivery.
General Contracting & Erection
Foundation work, building erection, and full project management from groundbreaking to certificate of occupancy, self-performed or managed through our vetted subcontractor network.
Engineering & Code Compliance
Structural engineering coordinated to meet Washington’s specific wind, snow load, and seismic design requirements for your site and jurisdiction.
A structured, transparent process from first conversation to final walk-through.
How We Build Your Pre-Engineered Metal Building
Pre-engineered metal building construction involves a lot of moving parts — and the difference between a smooth project and a costly one often comes down to how early you get the right contractor involved. Sea Con engages at the earliest stages so that feasibility, structural system options, and budget expectations are aligned before a single dollar is committed to design.
01
Pre-Construction & Feasibility
We start by understanding your project: site conditions, building use, clear-span and height needs, and budget parameters. Our team conducts site evaluations, provides preliminary construction budgets, and evaluates structural system options — including PEMB, hybrid, and conventional construction — so you can make an informed decision before committing to a design direction.
02
Design Coordination & Permitting
SEA CON manages the design and drafting process through engineering, construction documents, and permit submission. We act as your advocate throughout — flagging constructability issues early, driving value engineering opportunities, and coordinating directly with your PEMB manufacturer. Our familiarity with Washington permitting agencies helps keep projects moving through the approval process.
03
Construction & Erection
Once permits are in hand, SEA CON manages the full construction process — overseeing foundation work, building erection, and a vetted network of specialty subcontractors. Our project management team maintains detailed schedules, tracks budgets in real time, enforces safety protocols, and communicates proactively so there are no surprises at closeout.
04
Turnover & Post-Construction Support
We don’t disappear at the finish line. SEA CON provides complete project closeout documentation, coordinates final inspections and certificate of occupancy, and remains available for post-construction support as your facility opens and begins operations.
Built for the Pacific Northwest.
Ready for Any Industry.
Most regional contractors can put up a basic metal building. Engineering a PEMB to perform reliably across Washington’s varied conditions — heavy rain in Bellingham, snow loads in Skagit County, seismic requirements statewide — is a different challenge entirely, and it’s where Sea Con separates itself from the field.
PEMB construction requires structural engineering coordination, manufacturer management, code compliance across multiple jurisdictions, and a contractor with the workforce and insurance coverage to execute efficiently at scale. Many contractors in the Pacific Northwest simply aren’t equipped for it. SEA CON is.
We’ve delivered pre-engineered metal building projects throughout Washington, Oregon, and Idaho — from manufacturing plants and warehouses to aviation hangars and vehicle dealerships. Our team understands how to manage the coordination layers that come with PEMB construction, and we bring that experience to every project we take on.
