Risk allocation in contracts I: principles and key clauses

Most risk transfer on a construction project happens through the contract. Before any insurer or surety becomes involved, the owner and contractor have already decided, clause by clause, who pays when the ground is worse than expected, when a worker is injured, when the design has an error or when the project finishes late. CON-220 explains the law of contracts and the standard forms in detail. This lesson and the next look at the same clauses through a risk lens: what each clause does to the allocation of risk, how it interacts with insurance, and what a contractor or owner should check before signing.

Principles of good allocation

Lesson 1 introduced the principle that a risk should go to the party best able to control it, or failing that, the party best able to bear it at the least cost. In practice several further tests are applied by experienced drafters and by owners' advisers.

Owners sometimes believe that a contract transferring every risk to the contractor is the safest choice. It rarely is. Bidders price risks they cannot control at a premium, often a large one; the best contractors may decline to bid; and when a risk too large for the contractor occurs, the result is a dispute, an insolvency or a project that stops. Many public reviews of failed projects, including transit P3s in both countries discussed in CON-340 lesson 7, have concluded that risk was transferred to private parties who could not manage it, and that the public owner ended up paying anyway.

Indemnities

An indemnity is a promise by one party to protect another against specified losses, usually claims by third parties. In a construction contract the contractor typically indemnifies the owner against claims arising from the contractor's work, such as a passer-by injured by falling debris or a neighbour whose building is damaged by vibration. The owner may indemnify the contractor against claims arising from its own acts or from conditions it is responsible for.

In Canada, CCDC contracts use mutual indemnities limited by reference to the insurance the contract requires and to each party's fault, and courts generally read an indemnity as covering the indemnified party's own negligence only if the clause says so clearly. Owners who rewrite the CCDC indemnity into a broad, unlimited form create a risk that the contractor's insurance will not cover, because liability policies respond to the insured's legal liability and to contracts the insurer has agreed to cover. A contractor asked to sign an unlimited broad-form indemnity should take it to its broker before signing.

Indemnities and insurance work together. The contractor's commercial general liability policy, discussed in lesson 8, usually covers liability the insured assumes under an insured contract, which typically includes many indemnities given in construction contracts, subject to the policy terms. That coverage is why owners require contractors to carry liability insurance and to name the owner as an additional insured. But an indemnity broader than the coverage leaves the contractor paying from its own pocket.

Limitation of liability

A limitation of liability clause caps the amount one party can recover from the other. Designers routinely seek caps tied to their fee or their professional liability insurance limit. Contractors seek caps on their total liability, often tied to the contract price, and especially on liquidated damages, which are frequently capped at a percentage of the contract price, such as 5 to 10 %. Owners resist caps because they leave the owner exposed above the cap, but a reasonable cap often lowers the price and widens the field of bidders.

Caps usually exclude certain liabilities, such as fraud, intentional misconduct, gross negligence, third-party bodily injury and amounts recovered from insurance. Courts in both countries generally enforce clear caps between sophisticated commercial parties, though they may refuse to enforce a cap in cases of serious misconduct or where enforcement would be unconscionable. CON-220 covers the legal tests.

Waiver of consequential damages

Consequential damages are indirect losses that flow from a breach, such as an owner's lost revenue or rent while a building is late, or a contractor's lost profit on other work because its resources were tied up. They can be enormous compared with the contract price, and they are hard for the other party to price. Many standard forms therefore include a mutual waiver: each party gives up its claim to consequential damages against the other.

CCDC 2-2020 does not contain a broad waiver in the American style, although it limits some claims through its waiver of claims and indemnity provisions; owners and contractors in Canada often negotiate a mutual waiver of consequential and indirect losses in supplementary conditions. Because the line between direct and consequential loss is not always clear, careful drafters list the specific losses waived, such as loss of use, lost revenue and lost profit, rather than relying on the word consequential alone.

The waiver and liquidated damages clause are closely linked. Liquidated damages usually represent the owner's agreed recovery for delay, replacing the uncertain consequential losses the owner might otherwise claim. An owner that strikes the waiver and keeps a low liquidated damages rate may argue it can claim actual losses above the rate; a contractor should make sure the contract says liquidated damages are the owner's sole remedy for delay.

Warranties and guarantees

A warranty allocates the risk of defects that appear after completion. Standard construction contracts give a one-year correction period, during which the contractor must return to fix defective work, and the owner keeps its legal rights for latent defects beyond that period, subject to limitation periods. Specific systems often carry longer manufacturer warranties, such as twenty years for a roofing membrane. Owners sometimes ask for extended contractor warranties or performance guarantees, for example a guarantee that the pool's dehumidification system will hold the hall at a stated humidity. These shift performance risk to the contractor and should be priced and, where possible, backed by the manufacturer.

Reviewing a contract for risk

Contractors who review an owner's contract before bidding usually work from a checklist of high-risk clauses. A clause-by-clause review compares the owner's terms with the standard form it was based on, flags each change, and decides whether to price it, qualify the bid, ask for clarification during the tender, or decline to bid. CON-220 lesson 4 discusses supplementary conditions; from a risk point of view the point is to know what each change does to exposure.

# Scoring an owner contract against a risk checklist (illustrative)
clauses = {
    # clause: (owner amendment present?, severity 1-5 if present)
    "Broad-form indemnity":            (True, 4),
    "No cap on liquidated damages":    (True, 3),
    "Consequential damages waiver deleted": (True, 5),
    "Contractor accepts design":       (False, 5),
    "No differing site conditions clause": (False, 5),
    "Pay-if-paid to subcontractors":   (True, 2),
    "Extended 3-year warranty":        (False, 2),
}
flags = {k: s for k, (present, s) in clauses.items() if present}
score = sum(flags.values())
for k, s in sorted(flags.items(), key=lambda kv: -kv[1]):
    print(f"{s}  {k}")
print(f"Total risk score {score}; decision: {'qualify or price' if score < 12 else 'escalate to executive'}")

5  Consequential damages waiver deleted
4  Broad-form indemnity
3  No cap on liquidated damages
2  Pay-if-paid to subcontractors
Total risk score 14; decision: escalate to executive

Scoring of this kind is crude, but it forces a consistent review and makes it easy to escalate unusually risky contracts to senior management. The weights should reflect the firm's own experience of which clauses have cost it money.

Insurance requirements as allocation

The insurance article of a contract is itself a risk allocation tool. By requiring the contractor to buy builder's risk, general liability with stated limits, automobile, pollution or professional coverage, and by requiring the parties to be named as insureds and to waive subrogation, the contract decides which losses will be paid by insurers and which will fall back on the parties. A contract with a generous indemnity but low required insurance limits leaves a gap that the contractor carries itself. A contract that requires high limits for every trade may be safe on paper but drive up prices or exclude smaller subcontractors who cannot buy such limits. Reviewing the indemnity, limitation of liability and insurance clauses together, with the broker, is the only way to see the real allocation. Lessons 7 and 8 cover the insurance products themselves.
