Types of Construction Delivery
In Canada, there are three specific methods of Construction Delivery as follows:
- Design-Bid-Build (Stipulated Price Contract)
- Construction Management (CM)
- Design-Build (DB)
The following chart offers a description and the potential advantages and disadvantages of each method.
(Stipulated Price Contract)
This is the most traditional method of engaging an architect.
|Construction Management (CM)||
This approach is commonly used on more complex projects.
In this approach the client contracts directly with a contractor for construction and the relationship is between the contractor and the architect.
What are the Client’s responsibilities?
The Client issues the Construction or Tender Documents, which include drawings and specifications, for contractors to review and base their tender bid(estimates for the cost of construction). The documents can be issued through Government websites, newspapers, construction association information technology sites, etc.
Once the Tender closes and all bids have been received, the Client selects the successful bidder – often the lowest bidder.
The Architect will then coordinate with the successful bidder to construct the project. At this stage, the Owner is typically responsible for reviewing the information presented and providing feedback and/or approval of the information, as well as coordinating with necessary regulatory organizations to obtain the necessary permits, etc.
This process may vary depending on the method of construction delivery (for example, design-bid-build projects versus design-build). During this process, the Architect will review with the Client what to expect.
What deliverables can you expect from the Architect and their Consultant team?
Site analysis, conceptual floor plans, basic building massing and preliminary mechanical and electrical concepts.
Document showing all design elements including structural, mechanical and electrical drawings.
