Why the contract is the owner's #1 risk tool

Every construction project carries risk: ground that is worse than expected, a late permit, a supplier that fails, a design that does not fit. The owner cannot remove those risks. What the owner can do is decide, before anyone signs, who carries each one, at what price and with what paperwork. The contract is where that decision is written down, and it is the one risk tool that still works after things go wrong.

Learning outcomes

• Explain why the construction contract is an owner's main risk tool, and how it differs from a risk register or insurance alone.
• Describe how an unamended CCDC 2-2020 splits common risks between owner and contractor, with the General Condition (GC) that governs each.
• Follow the five steps that take a risk from the register into the contract and then into day-to-day management.
• Spot the owner's decisions on Northgate that have to be made before tender, not after.

The lesson

A contract is a risk allocation, written in advance

Owners often think of the contract as the price and the scope. Those matter, but the more useful way to read a construction contract is as a list of answers to the question "what happens if?" What happens if the soil is soft? If the roofing supplier goes bankrupt? If the city stops the job? If the owner changes its mind about the office layout? Each answer moves money and time from one party to the other.

That is why the contract is the owner's first risk tool and not just one of many. A risk register records risks. A contingency budget pays for them. Insurance transfers some of them to an insurer. But only the contract decides, in a way that binds the other party, which risks the contractor has priced into its bid and which ones come back to the owner as change orders, time extensions and claims. If the contract is silent or vague, the answer gets decided later, usually by negotiation under pressure, by an adjudicator or by a court.

The price you pay depends on the risk you hand over

Contractors are not charities, and good ones are not reckless. When a tender asks a contractor to carry a risk, it prices that risk into the bid, adds a premium for uncertainty, or declines to bid. When the owner keeps a risk, the bid comes in lower, but the owner must budget for the risk and manage it.

The usual principle is that a risk should sit with the party best able to control it or absorb it. The contractor controls its own crews, methods, safety and subcontractors, so those risks sit naturally with it. The owner controls the design, the site it bought and the decisions it makes during construction, so those sit naturally with the owner. Some risks belong to nobody, such as a province-wide strike or a fire that neither party caused, and contracts usually share them: the contractor gets time but not money.

Pushing every risk onto the contractor through one-sided Supplementary Conditions looks protective on paper. In practice it raises bids, narrows the bidder list and invites claims when the contractor tries to recover what it could not price. A good contract is not the most one-sided one. It is the one where each risk has a clear owner, a clear price and a clear process.

How a standard CCDC 2-2020 splits common risks

Most Canadian stipulated price work uses CCDC 2-2020, the Canadian Construction Documents Committee's stipulated price contract. The standard form is a balanced starting point negotiated by owners, contractors, consultants and lawyers. Figure 1 shows how the unamended form places ten common risks. Later lessons go clause by clause; this is the map.

View the data

Risk	Where it sits	Carried by
Price of the defined Work	Stipulated Contract Price	Contractor
Means, methods and site safety	GC 3.1; OHSA constructor	Contractor
Defects found in warranty	GC 12.3, from RFT	Contractor
Delay beyond either party's control	GC 6.5.3: time, no cost	Shared
Third-party injury and damage	GC 13.1: each its share	Shared
Errors in the owner's design	Contract Documents	Owner
Concealed or unknown conditions	GC 6.4, if materially different	Owner
Owner- or consultant-caused delay	GC 6.5.1: time and cost	Owner
Pre-existing toxic substances	GC 9.2	Owner
Permits and work by owner's forces	GC 10.2; GC 3.2	Owner

A few of these deserve a closer look, because they are where owners are most often surprised.

Concealed or unknown conditions (GC 6.4). If either party finds subsurface or hidden conditions that differ materially from what the Contract Documents show, or from what is normal for the area, it must give written notice promptly; the standard window is five working days. The Consultant investigates and, if the difference is material, the Contract Price and Contract Time are adjusted through a Change Order or Change Directive. In plain terms, the owner carries the ground. A geotechnical report and a contingency are how the owner manages that.

Delay (GC 6.5). The form treats delay according to cause. Where the owner, the Consultant or someone they are responsible for causes delay, the contractor gets an extension and its reasonable costs (GC 6.5.1). Where delay comes from causes beyond the contractor's control and not the owner's fault, such as labour disputes or fire, the contractor gets time but not money (GC 6.5.3). The 2020 edition also narrowed relief for stop-work orders from a court or public authority (GC 6.5.2). Lesson 26 covers delay clauses in detail.

Toxic and hazardous substances (GC 9.2). Substances already on site before the contractor arrived, such as contaminated fill or asbestos in an existing structure, generally stay the owner's responsibility. The contractor must stop and report; the owner must deal with it and, in many cases, pay for the delay.

Insurance (GC 11.1) and indemnities (GC 13.1). CCDC 2-2020 ties the insurance period, the warranty period (GC 12.3) and the indemnity timelines to the new Ready-for-Takeover milestone instead of Substantial Performance. It also raised the standard general liability limit from $5 million to $10 million and added pollution liability. Under GC 13.1, neither party is liable to the other for indirect or consequential losses, which matters to an owner that would lose rent or operating revenue if the building is late.

Waiver of claims (GC 13.2). After Ready-for-Takeover, each party gives up claims it has not given notice of within set periods, with exceptions such as substantial defects noticed within six years. This is the contract quietly closing the door. An owner that does not track defects and give notice on time can lose rights it never knew it had.

Your leverage is highest before you sign

Figure 2 shows the idea every owner's rep repeats. While the owner is drafting the contract and the tender is open, it can decide any allocation it wants at almost no cost; bidders simply price what they see. Once the contract is signed, every change to the deal needs the contractor's agreement, and every change during construction costs money and time. By closeout, the contract is mostly being enforced, not shaped.

This is why the contract work that matters most happens in the months before tender: choosing the delivery method and form, writing the Supplementary Conditions, deciding which reports to include, setting allowances and cash allowances, and writing the schedule and payment specifications. After award, the owner's job shifts from shaping the risk to managing it.

From risk register to contract clause

Risk management and contract drafting are often done by different people who never compare notes. The risk register sits with the project manager; the contract sits with legal and procurement. Figure 3 shows how they should connect.

For every major risk on the register, the owner should be able to answer five questions. What is the risk? Who carries it under the contract? Which document says so: the Agreement, a GC, a Supplementary Condition or a specification section? How is it paid for: in the contractor's price, the owner's contingency, an allowance, insurance or a bond? And what process triggers relief: which notice, within how many days, to whom, with what records? If any answer is "we're not sure", that risk has not really been allocated.

Statute sits above the contract

In Ontario, some allocations are not up to the parties. The Construction Act sets holdback, lien rights, prompt payment timelines and adjudication, and contract terms cannot contract out of them. The Occupational Health and Safety Act assigns duties to the constructor whatever the contract says. A good contract works with these rules; a contract that ignores them creates false comfort. Lessons 23 and 24 cover prompt payment and holdback.

Northgate worked example

The Northgate Distribution Centre (fictional) is a 12,000 m² tilt-up warehouse in Vaughan for Northgate Logistics Inc. (fictional), delivered design-bid-build under CCDC 2-2020 with a Contract Price of $34.95 million and an owner contingency of $3.05 million. Tender closed on December 8, 2026 and the contract is executed on January 11, 2027. Before tender, the owner's representative ran a contract risk review. Five of the risks it worked through show how the contract does the work.

Notice the pattern. None of these decisions costs much on December 1, 2026. Every one of them is expensive to fix on June 1, 2027, when panels are being stood up and the contractor is pricing every gap in the documents as a change.

Owner's move

• Demand a risk allocation table before tender. One page that lists the top 15 to 20 risks, who carries each one under the contract, the clause that says so, and how it is funded. If your consultant or lawyer cannot produce it, the contract has not been reviewed for risk.
• Check the Supplementary Conditions against that table. Every amendment to the standard form should move a specific risk for a specific reason. Delete amendments copied from another project that nobody can explain.
• Reject blanket risk transfer. Clauses that make the contractor responsible for "all conditions whatsoever" or waive every delay claim raise prices and seldom survive a dispute intact. Keep the risks you can manage and pay for the ones you transfer.
• Put the notice clauses in the project's operating rules. GC 6.4's five working days and the delay notice periods should be in the kickoff agenda, the meeting minutes template and the owner team's checklist.
• Get legal advice on the final form. Use a construction lawyer for the Supplementary Conditions, and an insurance broker for GC 11 and the bonding requirements.

Common mistakes

1. Treating the contract as procurement paperwork. The form is filled in at the last minute by someone who was not in the risk workshop, so the register and the contract never meet.
2. Over-amending the standard form. Heavy, one-sided Supplementary Conditions scare off good bidders and do not stop claims; they just change what the claims argue about.
3. Leaving reports out of the tender. An owner that withholds a geotechnical or hazardous materials report does not shift the risk. It weakens its own position when conditions turn out to be different.
4. Forgetting the owner's own obligations. Permits, owner-supplied equipment, timely decisions and payment are owner risks. Late owner decisions are one of the most common sources of compensable delay.
5. Ignoring notice and waiver periods. Owners hold contractors to notice deadlines and then miss their own defect notices after Ready-for-Takeover.

Quick quiz

1. Why is the contract described as the owner's main risk tool?

   1. It is the only document the contractor signs
   2. It binds both parties to a decision on who carries each risk and how relief is triggered
   3. It replaces the need for insurance
   4. It guarantees the project finishes on time

2. Under an unamended CCDC 2-2020, materially different concealed site conditions are mainly whose risk?

   1. The contractor's, because the price is stipulated
   2. The consultant's
   3. The owner's, through an adjustment under GC 6.4
   4. Nobody's; they are excluded

3. A fire that neither party caused delays the work. Under GC 6.5.3 the contractor usually gets:

   1. Time and money
   2. Money only
   3. Time but not money
   4. Nothing

4. When is the owner's leverage over risk allocation highest?

   1. Before the contract is signed, while the tender is being prepared
   2. At the first progress payment
   3. At Substantial Performance
   4. During the warranty period

5. Which is the best reason to avoid pushing every risk onto the contractor?

   1. The CCDC forbids any amendments
   2. Contractors price, or refuse, risks they cannot control, which raises bids and invites claims
   3. Insurance covers every risk anyway
   4. Ontario law makes the owner liable for all risks

Show answers and explanations

1. B. The register and insurance help, but only the contract binds the other party to who carries each risk, at what price, and through which notice and change process.
2. C. GC 6.4 provides for a price and time adjustment where conditions differ materially, after notice and the Consultant's investigation.
3. C. For delays beyond the contractor's control that are not the owner's fault, the standard form gives a time extension without payment for the delay costs.
4. A. Before signing, the owner can set any allocation and bidders price it. After signing, every change to the deal needs agreement and costs more.
5. B. Risk you transfer is risk you pay for. Unmanageable transfers raise prices, reduce competition and tend to come back as disputes.
