Summary
This Practice Tip (PT) offers information on alternative forms of project delivery through the utilization of a
construction manager’s (CM) services and the 2010 suite of three Canadian Construction Documents
Committee (CCDC) construction management contracts. Separate PTs have been prepared for each of the
three new CCDC CM contracts.
What Is Construction Management?
Construction management is a term for alternative forms of project delivery where a construction manager
replaces the role a general contractor has in traditional design-bid-build delivery. The owner still engages an
architect to design and prepare construction documents, but also engages a CM at an early stage as a
consultant to provide advice, oversee and manage construction: planning, costs, scheduling, methods and
materials. This CM could be a contractor, an architect or engineer, a consulting person or other entity as long
as they have the necessary construction expertise and trust of the owner. The CM may also be brought on
board after construction documents have been prepared. The CM will have a full time person on site acting as
a site superintendent the same way that a general contractor does in traditional project delivery.
The philosophy behind the benefits of CM is similar to that currently ascribed to Integrated Project Delivery;
bringing a more comprehensive team together for collaboration during design and the ability to start
construction earlier than with traditional design-bid-build. In construction management, instead of bidding by
general contractors, packages of work are bid for by individual trades, organized by the CM. Excavation,
foundations or structure could be bid before the construction documents are completed for all the interior
works. The individual trade contracts can be signed either with the owner or with the CM, which creates the
two basic variations in construction management – one with CM as advisor providing consulting services only;
and the other being a CM as advisor plus contractor providing consulting services and doing the construction.
In one scenario the owner signs contracts directly with the trades and the CM provides advice and
management only – often referred to as CM as Agent. Alternatively the CM signs all the contracts with trades,
and takes on the risk of the construction performance and the cost and schedule for the same, while still
providing construction management advice in the early stages – often referred to as CM at Risk.
The cost of the construction can be set up in several ways: cost plus (minimal risk to the CM), a guaranteed
maximum price (GMP), a fixed price (maximum risk to CM) or various arrangements of GMP with a sharing of
cost savings between the owner and CM.
History of Construction Management
When construction management is described as “starting construction before the plans and specs are done”,
it shows that the process has been around since the time of the pyramids. Owners acted as general
contractor by utilizing their own construction expertise or by hiring outside entities. The multiple trade works
were done through contracts directly to the owner. The owner had the control and responsibility that normally
rests with a general contractor. Some owners prefer this extra control, some like the extra control but not the
added risk.
