CCDC 30-2025: IPD and the Big Room

Integrated project delivery puts the owner, the designer, the builder and the key trades into one contract, pays their costs, and puts their profit at risk against a shared target. CCDC 30-2025 is the second Canadian edition of that model. It gives an owner more transparency and influence than any other CCDC form, but it also asks the owner to give up most of its claims against the team. This lesson explains how the 2025 form is organized, how the money moves, how the Big Room works, and when an owner should walk away at Validation.

Learning outcomes

• Explain how CCDC 30-2025 replaces separate design and construction contracts with one multi-party agreement, and how its Segments A, B and C are organized.
• Describe the compensation model: reimbursable costs, the Profit Pool, the Base and Final Target Cost, and Added Value Incentive Items.
• Set up the governance tiers, the optional IPD Advisor and a working Big Room.
• Treat the Validation Report as a real go or no-go decision, using a Northgate hypothetical with illustrative numbers.

The lesson

One agreement instead of three

On a design-bid-build project the owner signs a consultant agreement and a construction contract, and the contractor signs its own subcontracts. Each contract has its own price, its own risk transfer and its own claims process. Lesson 3 compared the delivery methods; IPD is the one that removes the walls between those contracts. Under CCDC 30, the Owner, the Consultant, the Contractor and, where it makes sense, key trade contractors and suppliers all sign the same agreement. They share one set of Project Objectives, one target cost and one pool of profit.

What changed in the 2025 edition

CCDC first published CCDC 30 in 2018 and released the 2025 edition on June 30, 2025, together with the new construction management forms (CCDC 5A, 5B and 17). Canadian law-firm commentary points to these changes:

• Three segments that follow the project. The Articles of Agreement are now split into Segment A (Validation, A-1 to A-4), Segment B (Project Execution, B-1 to B-4) and Segment C (General Articles, C-1 to C-11), followed by the General Conditions.
• Risk Pool renamed Profit Pool. Article C-4 calls it the Profit Pool, a name that better describes what is actually at risk.
• Clearer reimbursable costs. Schedule B now lets the parties designate each cost category as either reimbursable or overhead, and the audit rules were tightened.
• Added Value Incentive Items (Article C-3) can now be selected during construction, not only during design.
• Contract Amendments replace change orders for changes to the Project Objectives, target costs, Milestone Schedule and Profit Pool.
• Ready-for-Takeover is added, borrowed from CCDC 2-2020, as the milestone that moves the project into the Warranty Phase. Lesson 7 covers that milestone in depth.
• Prompt payment alignment in the General Articles, to fit provincial regimes such as Ontario's.
• Collaboration tools written into the contract: an optional IPD Advisor, Lean tools and practices, the Big Room and Key Personnel clauses.
• Termination is clearer, including a structure for what happens if the Validation Report is not accepted (A-4) and a new right to cure default.

Validation: the decision point

Validation is the first stage after signing. The team studies the owner's requirements and the site, then delivers a Validation Report with a Base Target Cost, a Milestone Schedule, a Contract Tasks Matrix, a risk and contingency analysis, and each party's disclosed cost and profit expectations. The owner then decides whether to proceed, adjust or withdraw. Commentators are blunt that this is a decision, not a formality: it is the owner's last clean exit before the target and the profit structure lock in.

How the money works

CCDC 30 is a cost-reimbursable contract with a target. Each team member is paid its actual reimbursable costs under the rules set at Validation. Its expected profit does not go into its rates. It goes into the Profit Pool, funded in proportion to each party's contribution, and stays at risk until the agreed objectives are met. If actual cost runs over the target, the overrun is taken out of the pool. If cost comes in under, the savings are shared on terms fixed in advance. Payouts are made at defined milestones and at the end of the Warranty Phase.

The owner's exposure is the part new IPD owners miss. Once overruns wipe out the pool, the team has no profit left to lose, but the owner still pays all reimbursable costs. And because the parties waive most claims against each other, the owner generally cannot sue a team member to recover costs above the target. The waiver has exceptions, which commentators list as wilful default, express warranties, amounts due, and substantial defects not reasonably discoverable before the Warranty Phase ends. The 2025 forms also carry a mutual waiver of consequential damages.

Governance and the Big Room

The contract runs on three tiers. A Senior Management Team (SMT), with a senior person from each party, sets direction and settles what the level below cannot. A Project Management Team (PMT) runs the project day to day, prepares the Validation Report, develops the audit procedures and is the first tier of conflict resolution. Project implementation teams do the design and construction work. Decisions under the 2018 edition were largely unanimous, and commentators noted that the standard terms gave no fast way to break a stalemate, so owners should test the escalation path before they need it. The 2025 edition lets the parties appoint an IPD Advisor to coach a team that is new to the model.

The Big Room is the physical place where this happens: a shared space where the team co-locates, meets on a fixed rhythm, plans with Lean tools and solves problems while they are still small. The 2025 edition names it, along with Lean tools, rather than leaving it to good intentions. In practice, the Big Room is where the team runs pull planning, tracks the cost against target every week and works through design options with the people who will build them.

Northgate worked example

Northgate Distribution Centre (fictional) was procured design-bid-build under CCDC 2-2020, with Ridgeline Architects Inc. (fictional) under OAA 600 and Halvorsen Builders Ltd. (fictional) as general contractor. See the Northgate fact sheet. Here is a clearly hypothetical question: what if Northgate had been procured as IPD under CCDC 30-2025? Every number below is illustrative, chosen to make the mechanics visible.

The signatories would be Northgate Logistics Inc. (fictional), Ridgeline, Halvorsen and the trades that drive the risk on a tilt-up warehouse with ESFR sprinklers: the concrete and tilt-up panel trade, the sprinkler trade, and the mechanical and electrical trades. In place of a tender that closed on December 8, 2026, the team would spend the Validation phase producing a Validation Report. Assume, for comparison, that it set a Base Target Cost of $34,950,000, equal to the real Contract Price, made up of $33,200,000 of estimated reimbursable costs and overhead and a Profit Pool of $1,750,000. Assume savings below target are split 50/50 between the owner and the team. CCDC 30 leaves that split to the parties.

View the data

Scenario	Reimbursable cost	Pool payout	Owner's total
A. $600,000 under	$32,600,000	$2,050,000 ($1,750,000 + 50% of $600,000)	$34,650,000
B. On target	$33,200,000	$1,750,000	$34,950,000
C. $900,000 over	$34,100,000	$850,000	$34,950,000
D. $2,500,000 over	$35,700,000	$0	$35,700,000

Read scenarios C and D together. In C the overrun is absorbed by the team's profit and the owner's cost does not move. In D the overrun of $2,500,000 is larger than the $1,750,000 pool, so the extra $750,000 lands on the owner, and the owner has waived most of the claims that would have let it recover that amount. On the real Northgate project, a $750,000 overrun would draw on the $3,050,000 owner contingency. Under IPD the owner still needs that contingency, for scope it adds and for the part of any overrun that exceeds the pool.

The Big Room would sit in the site office in Vaughan from mobilization. Before the tilt-up panels go up, the concrete trade, Halvorsen and Ridgeline's structural subconsultant would pull-plan the panel sequence back from the M5 milestone (panels erected, Friday June 25, 2027), and the PMT would review cost against target in the same room every week.

Owner's move

• Decide at Validation, on purpose. Read the Validation Report as if it were a tender. If the Base Target Cost does not fit the business case, adjust or exit under A-4.
• Size the pool against your risk. A Profit Pool that is small relative to plausible overruns gives the team little to lose and leaves you with the excess. Model scenario D before you sign.
• Keep your contingency. IPD reduces claims; it does not remove the owner's cost exposure above the pool.
• Put audit rights to work. Use the Schedule B cost categories and the audit procedures from the PMT, and sample costs monthly, not at the end.
• Staff the PMT with a decision-maker. An owner representative who has to go back to head office for every answer slows the whole Big Room.

Common mistakes

1. Treating Validation as paperwork. It is the owner's last clean exit before the target and pool lock in.
2. Assuming the pool caps the owner's cost. It caps only what the team can lose. Costs beyond it are still reimbursed by the owner.
3. Using change orders. Changes to targets, the Milestone Schedule or the pool go through Contract Amendments under the 2025 form.
4. A Big Room in name only. A room booked once a month is not co-location. Set the rhythm and the attendance in the Validation Report.
5. Leaving out the trades that carry the risk. If the riskiest scopes sit outside the agreement, their risk sits outside the pool.
