What is design-build, and how is it different from hiring a general contractor?

Design-build means one firm holds both the design and the construction contract and carries the project from first sketch to final inspection. A traditional general contractor builds from drawings someone else produced, which creates a handoff, and a gap, between the architect and the builder. Design-build closes that gap. One team owns the outcome, so there is no finger-pointing when something on paper meets the reality of the site.

That is the short answer. The rest of this article covers how the two models actually work, where each one fits, what to ask before you sign, and how EDDA applies design-build to projects of every scale across Greater Victoria.

The traditional route: design-bid-build

Most people who have commissioned a building have done it the traditional way, even if they never heard the name for it. The model is called design-bid-build, and it runs in three separate stages with three separate relationships.

• Design. You hire an architect or designer. They produce the drawings and specifications, usually with engineers as sub-consultants.
• Bid. Once the drawings are complete, the project is tendered. Several general contractors price the same set of documents and you pick one, typically on price.
• Build. The winning contractor builds what the drawings show. Anything the drawings did not anticipate becomes a change order.

The structure has real strengths. The design is finished before it is priced, so the bids are comparing like for like. The architect acts as an independent check on the contractor. And for public projects, it is often the only procurement route allowed.

The weakness is the handoff. The design is complete before a builder has ever priced it, which is exactly where budgets and schedules tend to slip. The drawings promise one thing, the bids say another, and reworking the design costs weeks. During construction, the contractor and the architect answer to you separately, so when a detail does not work on site, the conversation about whose problem it is happens on your time and your budget.

The design-build route: one team, one contract

Design-build collapses those three stages into one relationship. You sign a single contract with a firm that is responsible for both the design and the construction. The designers and the builders are on the same team, working for the same client, from the first conversation.

Three things change as a result.

• Pricing develops alongside the design. Instead of finishing the drawings and hoping the bids land, the budget is bracketed at concept and reconciled to the detailed drawings before construction starts. The number is real before the first cut is made.
• Design and construction overlap. Permits, procurement, and early site work can start while later design details are still being finalized. On a project with a fixed opening date, that overlap is often the difference between making the date and missing it.
• Accountability sits in one place. When a detail on paper meets the reality of the site, the team that drew it and the team that has to build it are the same people. The fix gets made. Nobody argues about whose fault it was.

The trade-off is that you are relying on one firm for both roles. The independent-architect check is gone, replaced by open-book pricing and a team whose reputation depends on the finished building. Choosing the right firm matters more, not less.

When each model makes sense

Design-build is the right fit for most private commercial and residential projects, and especially when any of the following is true:

• The opening date is fixed and cannot move (a lease commencement, a school year, a tourism season).
• The budget needs to be real early, before financing or a lease is committed.
• The project is a renovation or tenant improvement in an existing building, where surprises behind the walls are certain and the design has to adapt.
• You want one point of contact and one accountable party rather than refereeing between two.

The traditional route, or general contracting from a finished set of drawings, still makes sense when the design is already complete, when procurement rules require competitive tender, or when you have a long relationship with an architect you want to keep in the lead role. EDDA works this way too. The difference is the contract structure, not the standard of care.

For larger or multi-phase projects where you want to hold trade contracts yourself, construction management is a third option that sits between the two.

What to ask before you sign a design-build contract

Because design-build asks you to trust one firm with both roles, the questions you ask up front carry more weight. Five worth asking any design-build firm in Greater Victoria:

• Who is actually on my project? Ask for the names of the principal, the designer, and the site lead, and whether they stay through closeout. On EDDA projects, senior leadership is on site regardless of project size.
• How is pricing developed and shown? Look for open-book pricing that is reconciled to the drawings before construction, not a lump sum with no visibility.
• What happens when the site does not match the drawings? The honest answer is that it always happens on renovations. What you want to hear is how the firm handles it without a change-order fight.
• Can I see completed work at my scale and in my building type? A firm that has delivered fifty completed projects in your market has a track record you can walk through.
• Who handles permits, consultants, and the municipality? In true design-build, the firm carries all of it. If the answer involves you managing engineers or permit applications yourself, it is not really one contract.

How EDDA applies design-build

For EDDA this is the flagship model across every scale of work. A 1,500 sq ft restaurant fit-out and a 30,000 sq ft ground-up building run through the same integrated process: a conversation about what the building needs to do, then concept design, detailed design, and construction, without changing partners or signing a new contract.

The discipline was learned in hospitality, where lease dates do not move and kitchens have to pass inspection the first time. It now runs through everything the firm delivers in Greater Victoria, from major renovations and building exteriors to ground-up construction, commercial and residential alike. One team. One contract. From first sketch to final inspection.

Frequently asked questions

Is design-build the same as a general contractor?

No. A general contractor builds from drawings produced by a separate architect or designer under a separate contract. A design-build firm holds both the design and the construction contract, so one team carries the project from concept through construction. Many design-build firms, including EDDA, also offer general contracting when the design is already complete.

Is design-build cheaper than design-bid-build?

Design-build typically delivers better cost control rather than a lower headline price. Because pricing develops alongside the design and is reconciled before construction, change orders, the largest source of cost growth on traditional projects, are sharply reduced. The final number is more likely to match the first one.

Is design-build faster?

Usually, yes. Design and construction can overlap, so permitting, procurement, and early site work start while later details are still being finalized. The saving is largest on projects with a fixed opening date.

Does design-build work for renovations and tenant improvements, or only new buildings?

Design-build is especially well suited to renovations and tenant improvements, because existing buildings always hold surprises and the design has to adapt as they are uncovered. Having the designer and the builder on one team makes those adjustments fast and keeps them out of the change-order process.

Does EDDA offer design-build for residential projects?

Yes. EDDA delivers design-build for commercial, hospitality, retail, clinical, mixed-use, and residential buildings throughout Greater Victoria, including Victoria, Saanich, Oak Bay, Esquimalt, Langford, and Sidney.
