Pre-construction to construction handoff

Between the day the tender closes and the day the contractor moves onto site, a project changes hands. The people who designed it, priced it and bought it step back, and the people who will build it and control it step in. What the second group knows on day one depends entirely on what the first group writes down and passes on. This lesson is about making that handoff deliberate, so the owner does not lose in the first week what it spent a year of design and procurement building up.

Learning outcomes

• Explain why the handoff from pre-construction to construction is a risk point for the owner, not an administrative formality.
• List the documents in a complete owner's handoff package and say who prepares each one.
• Sequence the handoff tasks between tender close, contract execution, kickoff and mobilization.
• Apply a handoff checklist to Northgate's dates and spot what must be in hand before the kickoff meeting.

The lesson

Why the handoff is where knowledge leaks

In lesson 1 we placed the procurement phase just before gate G3, the contract award. Up to that gate, the project lives with a design and procurement team: the prime consultant, the owner's procurement lead, a cost consultant and usually the owner's PM. After it, the project lives with a construction team: the owner's PM and owner's representative, the consultant in its contract administration role, and the contractor's PM, superintendent and scheduler.

Some people are on both teams, but rarely all of them. The estimator who levelled the bids moves to the next tender. The procurement lead who answered bidder questions goes back to the purchasing department. The design architect hands the file to a contract administrator in the same firm. Each of them carries knowledge that is not in the contract: why an alternate was rejected, what a bidder was told in a site meeting, which risk the owner decided to keep and how much contingency it set aside for it.

Contractors know this problem well from their own side, where the estimating team hands a won job to the operations team. Industry writing on the subject keeps finding the same causes: information passed as static files, teams that each keep their own version of the truth, and decisions left to be settled after site work starts, when they cost more. The owner's version of the problem is no different. The fix is also the same: decide in advance what must be handed over, put it in one place, and hold a meeting where the receiving team accepts it.

What the owner's handoff package contains

Figure 1 shows the handoff as a package passed from one team to the other. The package is a short, controlled set of documents, not a dump of every email from the tender period.

1. The contract as signed. The executed Agreement, the General Conditions, the owner's Supplementary Conditions and the list of Contract Documents. The construction team needs the version that was actually signed, not the tender draft. Under CCDC 2-2020 the Contract Documents are listed in the Agreement, and the order of precedence decides which document governs when two disagree.

2. The issued-for-construction set. Bid documents are amended during the tender by addenda. After award, the consultant can consolidate the drawings and specifications with all addenda and accepted alternates into one set, often called "issued for construction" or "conformed". The Ontario Association of Architects notes that such a set should be identical in content to the Contract Documents, and that issuing it formally, rather than "for convenience only", avoids confusion about its status. Ask for it, ask for it to be sealed, and make sure it introduces no design changes that were not in the contract.

3. The bid record. The contractor's bid form and any breakdowns, the addenda log, the bidder questions and answers, and any clarifications or exclusions accepted at award. These explain what the price includes. When a change order dispute starts six months later, the first question is usually "what did the bid include?"

4. The risk register. Every open risk, with a named owner, the response decided and the contingency set aside for it. Risks the owner kept under the contract (for example, materially different site conditions) need a construction-phase owner, not a procurement-phase one. See building a risk register owners can use.

5. Budget, contingency and cash flow. The approved budget broken down so it matches the contract, the owner's contingency and the rules for drawing on it, and a first monthly cash flow. The construction team will report against these numbers for the rest of the job.

6. The Owner's Project Requirements. The document that says what the building must do. It guides design reviews, submittal reviews and commissioning, and it is easy to forget once the drawings exist. See Owner's Project Requirements.

7. Permit status and authority conditions. Where the building permit stands, what conditions or comments are outstanding, and any site plan or development agreement obligations the work must meet. Under Ontario's Building Code Act, construction of a building needs a permit before it starts, so a late permit is a direct threat to the mobilization date.

What the contractor must deliver in the same window

The handoff is not only internal. Between execution and mobilization, the contract also requires deliverables from the contractor that the construction team must chase and check:

• Insurance and bonds. CCDC 2-2020 GC 11.1 requires the contractor to carry the insurance set out in the contract, and owners' Supplementary Conditions usually require certificates of insurance before the Work starts. Where the contract requires performance and labour and material payment bonds, owners commonly set a short deadline after execution for delivering them. See construction bonds for owners in Canada.
• The construction schedule. Under GC 3.4 the contractor must prepare a construction schedule and submit it before its first application for payment, then keep it updated. Many owners tighten this with a Supplementary Condition that sets a firm submission date and format. See how to set and lock a schedule baseline.
• Safety start-up. The constructor's obligations under Ontario's Occupational Health and Safety Act, including the Notice of Project, must be in place before work begins. Lesson 3 covers how the kickoff confirms them.

Sequencing: three checkpoints

A handoff that happens "sometime before site starts" usually happens on the first day of site work, which is too late. Tie each item to one of three checkpoints:

1. By contract execution. The signed contract and Supplementary Conditions, and the insurance and bond requirements the contractor must meet. If these are not settled, there is no contract to hand over.
2. By the kickoff meeting. The bid record, the risk register with construction-phase owners, the budget and contingency rules, and the Owner's Project Requirements. The owner's team must know all of this before it sits down with the contractor, or the contractor will set the agenda.
3. By mobilization. The issued-for-construction set, the permit, the owner's separate contracts (equipment, racking, IT) and the contractor's baseline schedule, or at least a firm date for it.

The internal handoff meeting

Hold a short owner-side handoff meeting between execution and kickoff. It is internal: the owner's PM, the owner's representative, the procurement lead and the cost consultant, with the prime consultant if useful. The contractor is not there. The agenda follows the package: walk through each item, confirm it is complete, and record who owns it from now on. Ninety minutes is usually enough.

Three questions make the meeting worth holding:

• What did we promise bidders? Any answer given in the tender period that is not in an addendum is a risk. List them.
• What did we decide not to buy? Rejected alternates, deleted scope and items left for the owner's separate contracts are where gaps open up during construction.
• What are we still waiting for? Outstanding permits, approvals, owner decisions and contractor deliverables, each with a date.

The meeting ends with the owner's PM accepting the package in writing. That note becomes the first document in the construction-phase file.

Northgate worked example

Northgate Distribution Centre is the fictional case study used across BRC Academy: a 12,000 m² tilt-up warehouse with a 900 m² office mezzanine in Vaughan, Ontario, for the fictional Northgate Logistics Inc., under a CCDC 2-2020 stipulated price contract of $34,950,000 with Halvorsen Builders Ltd. (fictional). The facts are on the Northgate fact sheet. Figure 3 shows the window this lesson covers.

Tender close to contract (December 8, 2026 to January 11, 2027). Halvorsen is the low compliant bidder. The owner's procurement lead and cost consultant level the bids, confirm the clarifications and prepare the contract for execution with the Supplementary Conditions. Before signing, the owner's representative checks that every addendum issued in the tender period is listed in the Agreement's list of Contract Documents.

The handoff meeting (Thursday, January 14, 2027). Three days after execution, the owner's team meets without the contractor. The procurement lead walks through the bid record and the tender questions. The cost consultant hands over the budget in the contract's format and confirms the $3,050,000 owner contingency. The owner's representative reassigns each risk on the register to a construction-phase owner; the subsurface risk under the slab, for example, moves from the procurement lead to the owner's representative, with part of the contingency held against it. The owner's PM confirms that Northgate's separate racking contract is scheduled to start after Ready-for-Takeover, on January 17, 2028, and flags it for the kickoff agenda.

Kickoff (Tuesday, January 19, 2027). Because the bid record, risk register, budget and requirements are already in the owner's hands, the owner's team arrives at the kickoff with its decisions prepared. Lesson 3 follows that meeting.

Issued-for-construction set (Friday, January 29, 2027). Ridgeline Architects consolidates the addenda into one sealed set and issues it through a Supplemental Instruction stating that it changes neither the Contract Price nor the Contract Time. The owner's representative spot-checks it against the addenda log before it goes to site.

Baseline, permit and mobilization (February 10 to March 1, 2027). Halvorsen's baseline schedule is due on February 10, thirty days after execution under the Supplementary Conditions. The building permit is issued on February 26. Halvorsen mobilizes on March 1. By then every item on the checklist in Figure 2 is either in hand or tracked with a date, and the construction team owns the project.

Owner's move

• Demand a written handoff package. Make it a deliverable in the consultant's and cost consultant's scopes, with the seven items listed, so it is paid for and expected.
• Check the list of Contract Documents against the addenda log. A missing addendum in the Agreement is a gap the contractor can price later.
• Reassign every risk. No risk on the register should still be owned by someone who has left the project.
• Insist on a formal issued-for-construction set, sealed and issued through the contract, with no unrecorded design changes. Reject a convenience set that introduces "small" revisions.
• Hold the internal meeting before the kickoff. Do not learn about a bidder clarification from the contractor across the table.

Common mistakes

1. Treating award as the end of procurement's job. The procurement team leaves the day the contract is signed, taking the reasons behind the deal with it.
2. Handing over the tender draft instead of the signed contract. The construction team then manages to the wrong Supplementary Conditions.
3. Letting the issued-for-construction set carry design changes. Changes slipped into a consolidated set without a change order invite disputes about what was bought.
4. Forgetting the owner's own separate contracts. Racking, equipment and IT contracts need access dates and coordination rules before the contractor's schedule is built.
5. Starting site before the paperwork. Mobilizing without insurance certificates, bonds, a permit or a schedule date puts the owner at risk from the first day.

Quick quiz

1. Why is the pre-construction to construction handoff a risk point for the owner?

   1. The contract price changes at award
   2. People who hold the reasons behind the deal leave the project
   3. The consultant stops working until mobilization
   4. The permit expires at contract execution

2. What should an issued-for-construction set contain?

   1. The bid documents plus all addenda and accepted alternates, with no new design changes
   2. The contractor's proposed design improvements
   3. Only the drawings changed by addenda
   4. The consultant's preferred revisions made after award

3. Under CCDC 2-2020 GC 3.4, when must the contractor first submit its construction schedule, unless the Supplementary Conditions say otherwise?

   1. Before the tender closes
   2. Before its first application for payment
   3. At Ready-for-Takeover
   4. Within 24 hours of mobilization

4. By which checkpoint should the owner's team have the bid record and the reassigned risk register?

   1. By final completion
   2. By the first progress payment
   3. By the kickoff meeting
   4. By the first schedule update

5. On Northgate, why does the owner hold its internal handoff meeting on January 14, 2027?

   1. Because the contractor must attend before the kickoff
   2. So the owner's team knows the bid record, risks and budget before meeting the contractor on January 19
   3. Because the building permit is issued that day
   4. Because CCDC 2-2020 requires a meeting three days after execution

Show answers and explanations

1. B. The estimator, procurement lead and design team carry knowledge that is not in the contract. If it is not handed over, the construction team works without it.
2. A. The set should consolidate what was bought. Design changes belong in the change process, not in a reissued set.
3. B. GC 3.4 ties the first schedule submission to the first application for payment. Many owners set an earlier, firm date in the Supplementary Conditions, as Northgate does.
4. C. The owner's team needs these before it meets the contractor, or the contractor will set the agenda.
5. B. The internal meeting is the owner's choice, not a CCDC requirement. Holding it before the kickoff lets the owner arrive prepared.
