CSTN 2380 – Construction Contract Documents Study Notes
Introduction to Construction Contract Documents
Material derived from the Canadian Construction Document Committee guides and contracts used in this course.
Learning Objectives
Enable students to:
Describe and evaluate the strengths and weaknesses of CCDC 2, the Design-Bid-Build (DBB) delivery method.
Identify the roles involved in the DBB delivery method.
Understand the key roles specified in CCDC 2.
Illustrate and describe the overall delivery model.
Design-Bid-Build Contracts
CCDC 2 is classified as a Stipulated Price Contract; it will serve as a reference throughout this course.
Alternative names for CCDC 2 include:
Lump Sum Tender
Traditional Delivery
Design-Bid-Build
Overview of the Design-Bid-Build Delivery Method
In the Design-Bid-Build (DBB) process:
The Owner employs a Consultant to design the project and represents the Owner throughout its execution.
Upon completion of the design, the project is put out to tender.
A contract is awarded to the Contractor that submits the lowest price while meeting bidding requirements.
Characteristics of Design-Bid-Build
It is recognized as the traditional delivery model.
The contractual relationships are as follows:
The Owner holds a contract with the Consultant.
The Owner enters into a separate contract with the Contractor.
Notably, there is no direct contractual relationship between the Contractor and the Consultant. Nevertheless, a collaborative working relationship is necessary since the Consultant acts as the Owner's representative.
Key Characteristics of Design-Bid-Build
The separation of responsibilities:
Design and construction tasks are handled by different entities.
The design must be fully completed before bidding occurs.
Project scope and quality details are clearly defined.
The Owner’s involvement:
High engagement is expected during the design phase and before the contract award.
Owner involvement may diminish during the construction phase.
Roles within CCDC 2
The Owner:
Responsible for funding and utilizing the project upon completion.
Signs a contract with the Consultant for project design and another contract with the Contractor for construction.
The Consultant:
Tasked with the design aspects of the project.
Acts on the Owner's behalf and certifies payments.
Reviews construction progress and evaluates submittals.
The Contractor:
Responsible forExecuting construction of the project.
Has a direct contractual commitment with the Owner and also manages contracts with Subcontractors.
Oversees construction operations and schedule management.
Cost of the Work
The Design-Bid-Build delivery system operates under a stipulated price framework:
Once the Owner accepts a bid, the agreed-upon construction price remains final, provided no changes to the project scope are made.
Cost overruns are absorbed by the Contractor, while any cost savings directly benefit the Contractor.
Financial Implications of the Cost Structure
This delivery framework offers significant cost certainty for the Owner:
The Contractor assumes the risks associated with potential cost overruns.
Any modifications requested by the Owner will adjust the contract total accordingly.
The Contractor is not obligated to disclose financial records to the Owner.
Schedule of the Work
The Contractor is responsible for creating and managing the project schedule:
The contract stipulates explicit start and finish dates as outlined in Article A-1.
