Design-build uses one team for design and construction; design-bid-build separates them. Design-build usually means better cost control and accountability, while design-bid-build offers more separation. Here's how to choose.
Two Different Ways to Renovate — One Is Almost Always Better
Most Calgary homeowners don’t know there are fundamentally different ways to structure a renovation project. Understanding them helps you make better decisions from the start.
Design-Bid-Build (Traditional)
You hire a designer, get construction drawings, then take those drawings to multiple contractors for bids, pick one, and they build it.
Pros
- Competitive pricing (multiple bids)
- Design is fully defined before construction starts
- Designer is a separate advocate for your interests
Cons
- Designer and contractor may not communicate well
- Problems discovered during construction can be costly (designer must be re-engaged)
- Longer overall timeline (design phase fully complete before any bidding)
- Scope gaps between design intent and construction reality are common
- Two contracts, two relationships, two sources of finger-pointing when things go wrong
Design-Build (Olympic City’s Model)
One firm handles design, planning, and construction under a single contract. The designer and builder are the same team from day one.
Pros
- Single point of accountability — one company responsible for everything
- Cost certainty earlier in the process (builder is in the room during design)
- Faster timeline (design and construction can overlap)
- Problems solved collaboratively (no blame game between designer and contractor)
- Better buildability — design details are developed with real construction knowledge
Cons
- Less competitive bidding (one price, not three)
- Requires trust in the design-build firm’s integrity
- You don’t get an independent designer as your advocate
Which Is Right for Your Calgary Renovation?
| Scenario | Recommended Method |
|---|---|
| Small/medium renovation ($30K–$150K) | Design-Build (simpler, faster) |
| Large custom home addition ($200K+) | Either — both work at this scale |
| Complex heritage or character renovation | Design-Bid-Build (independent architect valuable) |
| Simple renovation with clear scope | Design-Build |
| Complex multi-trade renovation | Design-Build (single accountability) |
