INTRODUCTION
TO CONTRACT ARRANGEMENTS
There are four main types of contracts conventionally used in
the construction industry, namely:
B)
COST PLUS
C)
PROJECT_MANAGEMENT/CONSTRUCTION MANAGEMENT
D)
A DEVELOPMENT PROPOSAL
· Tried and True Process
· Cost is known up front in the contract
· Competitive Bidding is Encouraged
· Transparent
· You do not necessarily have to accept the lowest bidder or any bidder
· Trust and reputation is important
· Slow Construction cant start without a full set of construction documents
· Money distribution can be difficult to manage: if the GC does not pay the TCs (Sub Contractors or Trade Contractors), you will get liens on the project and Architects are in the line of fire and can be held partly responsible
· Lacks flexibility for Design Changes
· Contractor can hide anticipated costs within Change Orders (COs) during the construction process
· During boom times, bids tend to be high
· TCs tend to blame each other if things go wrong (e.g., Mechanical blames Electrical)
·
Holdbacks are not very effective management
tools for ensuring project quality

COST_PLUS_CONTRACT
Also known as a Design/Build Contract, this contract involves the CCDC #3 forms where the contractor on a regular basis bills the client for construction materials and labour (TIME & MATERIALS). This includes the traditional individuals of contract work. The three major participants are the Client, a Design Professional and the General Contractor. It is commonly used when the scope of services is not well defined in the contract. This process tends itself to be a sequential construction method without the use of a full set of construction documents. This type of contract is well suited for renovations and small projects.
· Faster a complete set of working drawings is not required
· Retrospective calculation of costs
· Flexibility for change during work
· Can be cheaper because the Contractors do not have to price in unknownsthe client is taking on that responsibility
· Architects and Contractors try to pass on liability to Clients
· Total cost isnt well defined
· No commitment for reduced expenses by Contractor
· Requires close inspection and review of construction
· A high degree of trust between Architect and Contractor is required
·
Possibility of Client billing for construction
errors

· Flexible for design change
· Possibility of a fast construction start
· Time & Complexity of construction works well with a manager
· Can use a GMP approach (Gross Maximum Price) guaranteed by the GC and administered by the Project Managerthis gets the GC, PM and the Client on the same side of the table so to speak
· Competitively bid TCs only with GMP approach
· Overall lack of responsibility on part of Construction Manager
·
Tends to be more expensive to administrateClient
pays GC (10+10) and PM on top of this

Also known as a Build-To-Suit Contract or a Turnkey Project, this type of contract arrangement is based on the CCA #14 forms where a stipulated price is agreed with certain modifications given to the Developer. The Developer has total control of design and construction thus leaving the Client/Tenant/Investor/Institution with very little or no direct involvement. Often the Client will lease to own or purchase directly from the Developer upon project completion with a single tenancy. Includes land assembly, zoning, design, leasing, financing, project sale to REIT, Pen Fund, Bank, Public Co., Insurance Co., Investor, NGO, Owner-Occupier or other.
ADVANTAGES
· Fixed cost before construction
· Efficient construction time with little interference for changes
· Well suited for repetitive buildings or highly custom ones
· Low risk for Developers who have both tenant and investors lined up prior to start of project
· Limits the control of quality in materials and construction practices
· Typically uses standard architectural designs
· More expensive for the Clientoften an institutional buyer is paying for the Developers time, GC, PM and the cost of finding a long term tenant

CONCLUSIONS
STIPULATED
PRICE CONTRACT
Lending institutions are often more open to provide a mortgage where the total cost of construction is known beforehand. The contract also allows involvement in the design process where an architect works closely with the client.
COST
PLUS CONTRACT
This method is better suited for renovation or conservation work as opposed to new buildings. The scope of services is not well defined and involves a partial set of construction documents. Extra costs may increase during the construction stage.
PROJECT
MANAGEMENT CONTRACT
The use of a project manager is considered useful in larger projects, enabling them to act as the Clients Right Arm from the bid process through the construction phase.
DEVELOPMENT PROPOSAL CONTRACT
This is an exciting development in the field of contractsit allows the Industry to move toward a lower risk profile for the projects undertaken. By specializing in design and development and then sale of its products, individual companies can do many more projects at lower risk.
