Colony Construction delivers single-source design-build for US industrial projects – engineering, fabrication, and erection under one contract, with one schedule and one point of accountability. Our design-build approach follows DBIA (Design-Build Institute of America) best practices, engineers to AISC 360-22 and ASCE 7, welds to AWS D1.1:2020, and executes under OSHA 29 CFR 1926. Since 1985, across 700+ projects from Canadian remote mines to US manufacturing and oil and gas facilities, single-source design-build has compressed schedules by 20–40%, cut total delivered cost by 5–15%, and eliminated the interface risk that plagues traditional design-bid-build.
Design-Build Expertise
Design-build is a project-delivery method where one firm holds both the design and construction of a facility under a single contract. Instead of an owner contracting separately with an architect, a structural engineer, and a general contractor – then managing the interfaces between them – a design-build contractor integrates all three roles. Colony’s in-house engineers, Tekla detailers, project managers, fabricators, and erectors all work under one schedule, for one accountable team. On a US industrial site, that single-source model means fewer RFIs, fewer change orders, fewer “that’s not my scope” handoffs, and one signed warranty on the completed facility.
Colony offers lump-sum, guaranteed-maximum-price (GMP), and progressive design-build contract structures, selecting the one that fits each US owner’s risk profile and project maturity. On fast-track EV/battery plants and data-center shells, progressive design-build lets scope lock stage-by-stage while construction proceeds. On well-defined mining and oil and gas projects, lump-sum locks cost and schedule early. On owner-driven industrial programs, GMP shares savings with the owner when Colony beats the target. In every case, the owner sees one contract, one schedule, and one project manager – not a committee of interface agreements.

Challenges We Solve
Compressing Schedule Through Design-Construction Overlap
On a traditional design-bid-build project, design completes before bidding begins and construction starts after the contract is signed. Colony’s design-build runs design, fabrication, and construction in parallel – foundations poured while superstructure is detailed, erection starting on completed zones while later phases are still being engineered. On a typical US industrial project, that parallelism shaves 4–8 months off delivery.
Eliminating Interface Risk on Remote US Sites
On fly-in Alaska mines or remote Permian Basin sites, every coordination error between the designer and the builder is a week-long logistics penalty. Colony’s single-source design-build consolidates that coordination in-house – engineers sit at the same table as erectors, detailers coordinate directly with fabricators, and project managers own both sides of the design-construction line. The interface risk becomes an internal Colony problem, not an owner problem.
Cost Certainty for Capital-Budget-Constrained Owners
Owners planning capital programs against fiscal-year or IRA-funded budgets cannot absorb mid-construction cost creep. Colony’s lump-sum and GMP design-build structures lock cost early, with value-engineering built into design development rather than wedged in as late-phase change orders. On progressive design-build, scope locks stage-by-stage so the owner always has a current fixed price as scope clarifies.
State-by-State US PE Stamping Under Single-Source Delivery
US design-build requires state-licensed PE stamps for permits. Colony coordinates with a network of licensed US PE partners across Alaska, Washington, Oregon, California, Nevada, Arizona, Utah, Colorado, Texas, and Mountain West states, managing the engineer-of-record relationship under our single-source contract. The owner sees one Colony deliverable; the state sees a properly stamped drawing.
Constructability Feedback From Day One
Colony’s erectors review design decisions while the drawings are still in development. If a connection detail is hard to fit up in the field, we change it in Tekla before it hits the shop floor. If a crane pick looks ugly, we revise the member splice schedule before fabrication. That constructability loop – built into every Colony design-build job – is why our projects erect on schedule instead of running into field rework.
Projects We’ve Delivered
Brucejack Gold Mine
Single-source design-build on a fly-in-only gold-mining site where every piece of steel had to be engineered, fabricated, and installed as an integrated package. The remote-site coordination required by Brucejack directly parallels Alaska Donlin, Pebble, and Fort Knox remote-site design-build programs.
LNG Cedar Valley Lodge
Design-build workforce lodge delivered on an accelerated LNG-project schedule. Engineering, detailing, fabrication, and erection all managed under one schedule to meet the owner’s commissioning date. Representative of the Gulf Coast LNG workforce-housing and North Slope field-camp work Colony targets.
Dockside Green Biomass Energy Facility
A biomass energy plant delivered under a design-build model, with structural, cladding, and specialty industrial scope coordinated through one integrated team. Representative of the integrated process-facility design-build work Colony delivers for pellet mills, bio-refineries, and similar process plants across the Pacific Northwest and Central Valley.
Frequently Asked Questions
How does design-build compare to design-bid-build on US industrial projects?
Design-build puts one firm in charge of both design and construction under a single contract. Design-bid-build runs these as sequential contracts with separate firms, with the owner managing interfaces. Design-build is typically 20–40% faster and delivers better cost certainty; design-bid-build offers more owner control over design but carries more schedule and interface risk. On US industrial projects with aggressive schedules, design-build is almost always the right answer.
What cost and schedule savings can a US owner expect versus traditional delivery?
On industrial projects, design-build typically reduces total delivered cost by 5–15% compared to design-bid-build, primarily by eliminating coordination inefficiencies and late-phase value engineering. Schedule compression of 20–40% translates to significant indirect-cost savings on remote sites and fast-track reshoring programs. The savings are larger on remote and schedule-driven projects.
What contract structures (lump-sum, GMP, progressive) does Colony offer on US projects?
Colony offers lump-sum, guaranteed-maximum-price (GMP), and progressive design-build. Lump-sum works when scope is well-defined early. GMP shares savings with owners when Colony beats the target. Progressive design-build locks scope stage-by-stage as design clarifies – ideal for fast-track reshoring, data-center, and complex process projects.
How does single-source accountability reduce risk on remote US sites (Alaska, Mountain West)?
On remote fly-in mining sites, Alaska North Slope developments, or Mountain West wind-corridor projects, every design-construction handoff is a logistics penalty. Single-source design-build consolidates that interface in-house, so Colony – not the owner – absorbs coordination risk. One warranty, one schedule, one point of accountability from concept through commissioning.
Does Colony’s design-build team include licensed US engineers?
Colony’s in-house engineers are Canadian-licensed PEs. Stamped US drawings are delivered through a network of state-licensed US PE partners managed by Colony under our single-source contract. The owner sees one Colony deliverable per state; the state AHJ sees a stamped drawing under the correct US PE seal. We handle the engineer-of-record relationship end to end.
