Selecting the right project delivery method is key to ensuring a construction project runs smoothly, stays within budget and meets deadlines. For many different projects, engaging a construction manager offers advantages especially when timing and project complexities are present. Finding the right time to hire a construction manager for your project is an important step.
We will discuss when using a Construction Manager (CM) makes sense, the differences between CCDC 5A and CCDC 5B contracts and how these models can help manage risk and responsibilities throughout the project lifecycle.
When should you engage a Construction Manager?
When Timeline Constraints Limit Design Completion Preconstruction
Some projects must break ground before the design is fully finalized or when precise cost estimates are unavailable. A Construction Manager helps navigate this uncertainty by facilitating phased planning and real time cost assessments. This ensures progress without compromising project integrity.
When Early Partnership can Drive Practical and Sustainable Innovation
Involving the builder in the design discussions from the beginning allows for innovation and efficiencies. A CM provides practical insights into material choices, construction methods and sustainability opportunities. This allows for the design to remain feasible, cost effective and aligned with real world construction challenges. Therefore, builder’s feedback minimizes rework, optimizes resource use and enhances the project’s overall viability.
When Owners Need to Cost Control
Cost overruns present a significant concern in construction, especially in fluctuating market conditions. Engaging a CM gives owners access to proactive budgeting, risk assessment and transparent cost monitoring. A CM establishes a clear financial framework, identifies potential cost-saving measures and helps owners make informed decisions to keep the project within budget.
When Project Complexities are Present
Complex projects often involve multiple stakeholders, intricate design elements, and evolving scopes. When design and construction teams operate independently, misaligned expectations can lead to scheduling conflicts, design discrepancies, and scope changes that threaten project success. A CM serves as a bridge between design and construction, facilitating communication, resolving issues proactively, and mitigating risks to keep the project on track.
CCDC 5A vs. CCDC 5B: Choosing the right construction management contract for your project
The Canadian Construction Document Committee (CCDC) provides two primary contract models for engaging a Construction manager: CCDC 5A and CCDC 5B. Each of these contracts offers a different approach to managing risk and responsibilities, depending on the owner’s wants, needs and level of involvement.
CCDC 5A: Construction Management for Services
A CCDC 5A contract is ideal for owners who want to be actively involved in the project. Using this model:
- The owner retains trades directly and assumes responsibility for managing and supervising subcontractors.
- The construction manager provides oversight, advice and coordination but the owner maintains significant control over the process.
- This model works well for complex projects with specialized requirements, where the owner can use the construction managers expertise and support while maintaining project control.
- This could be a good option in projects with limited resources or projects with fixed budgets, the CCDC 5A model allows the Construction Manager to use economies of scale to procure materials efficiently which helps with cost savings.

CCDC 5B Construction Management for Services and Construction
The CCDC 5B shifts more responsibility onto the Construction Manager who acts similarly to a general contractor. Using this model:
- The Construction manager directly contracts with trades and subcontractors, reducing the owner’s administrative role.
- This model allows the owner to shift the risks and responsibilities associated with managing trades to the Construction manager.
- A CCDC 5B contract is a good fit for owners who prefer a more traditional approach, minimizing their role in day-to-day project management.

Risks associated with Construction Management contracts
- Under a 5A it is common for the contract to remain cost plus shifting budget over run risk to the owner.
- Under a 5A sub trade contracts are directly with the owner requiring additional administration.
- Under both forms of CM contract, the budget is not fully realised until the project is tendered at the end of design, which can lead to redesign costs.
- The design is contracted to the owner requiring additional management to ensure constructability input is included in the project.
Choosing the right type of contract depends on the owner’s project goals, resources and risk capacity. If you are looking for a more hands on approach, the CCDC 5A contract may be the best option. For projects where you want to minimize risk and administration duties, the CCDC 5B contract provides a more efficient approach by shifting more responsibilities to the Construction Manager. In both cases the owner needs to engage in the design process to ensure their requirements are met.
