Delay and rework are the two loss mechanisms that turn an ordinary construction contract into a claim, and they are worth separating because they are compensated differently. Delay is a loss of time that shows up as extended overhead, escalation and liquidated damages exposure; rework is a loss of productivity that shows up as labour hours expended twice for one unit of permanent work. A well-run claim distinguishes them, because the entitlement test for an extension of time is different from the entitlement test for disruption costs.

The reasons for delay fall into four groups that mirror the contractual allocation of risk. Owner-caused delays include scope changes and change orders, late release of the site or of a portion of it, late issue of permits and approvals, slow review of shop drawings and requests for information, owner-supplied equipment arriving late, interference by other contractors under the owner’s control, and late payment. Design-caused delays include incomplete or internally inconsistent drawings, specifications that conflict with the drawings, poor constructability, and design development that continues after tender. Contractor-caused delays include inadequate planning and an unrealistic baseline schedule, under-resourcing, poor subcontractor selection and subcontractor default, late procurement of long-lead items, plant breakdown, and poor site coordination. Neutral or external delays include abnormal weather, differing or unforeseen subsurface conditions, unrecorded utilities, archaeological or contaminated-soil finds, labour disputes, and regulatory or third-party railway and utility approvals.

Rework has its own, largely different, causes: errors and omissions in design that are discovered during installation; clashes between architectural, structural and mechanical work that were never coordinated in a model; changes issued after the work is in place; defective workmanship and non-conforming materials; damage caused by following trades; construction out of the planned sequence, usually as a response to an earlier delay; and poor document control, where a crew builds to a superseded revision. Acceleration is a notable multiplier — stacking of trades, extended overtime and shift work all reduce unit productivity and increase the error rate, so a delay that is answered by acceleration tends to generate the rework that then causes further delay.

Settlement approaches form a ladder, and Canadian standard-form contracts are written to keep disputes as low on that ladder as possible. The first rung is contract administration: timely written notice within the period the contract makes a condition precedent, a claim submission with supporting records, and a determination by the Consultant or Contract Administrator. Above that sits direct negotiation, first between project staff and then by escalation to senior executives outside the project. Where the parties have agreed to it, a standing dispute review board or project neutral issues a recommendation while the facts are fresh, which is the cheapest form of intervention because it happens during the work. Next comes mediation, a facilitated, without-prejudice negotiation that CCDC 2 Part 8 makes a mandatory step before arbitration. Several Canadian jurisdictions now also provide statutory adjudication under prompt-payment legislation, giving a rapid, interim-binding determination that preserves cash flow during the work. If those fail, the parties proceed to arbitration under the applicable provincial Arbitration Act and the CCDC 40 rules, which offers a decision-maker with construction expertise, a private hearing and limited appeal rights, or to litigation in the courts, which offers full discovery, the ability to join multiple parties, and appeal rights, at the highest cost and the longest timescale. Lien and trust remedies under the provincial builders lien legislation run alongside all of these as security for payment.

Validating a delay claim is a technical exercise, and the analyses divide into schedule analyses that establish entitlement to time and quantum analyses that establish entitlement to money. On the schedule side, the as-planned versus as-built comparison is the simplest and merely displays the two schedules side by side; it identifies where time was lost but proves nothing about cause. Impacted as-planned analysis inserts the alleged delay events into the baseline and re-runs the network, a prospective additive method that is easy to attack because it ignores what actually happened. Collapsed as-built, or but-for analysis, does the reverse: it removes the delay events from the as-built programme and observes how far the completion date retreats. Time impact analysis inserts each event as a fragnet into the schedule update that was current immediately before the event, and is the method the Society of Construction Law Protocol prefers for contemporaneous assessment. Windows or contemporaneous period analysis divides the project into intervals bounded by schedule updates and attributes the critical-path movement in each window to the events occurring within it; it is the most defensible retrospective method because it uses the network as it actually stood at the time.

Each of these must then be tested against the questions a tribunal actually asks. Was the delayed activity on the critical path, and did the critical path move? Who owns the float, given that most Canadian contracts treat float as a project resource available to whoever needs it first? Were there concurrent delays, one excusable and one not, in which case the usual outcome is an extension of time without compensation? Was the contractor pacing its own work in response to an owner delay, which is not a culpable delay at all? Was the baseline schedule reasonable and was it accepted? Was notice given? On the quantum side, the measured mile comparison of productivity in an unimpacted period against an impacted period is the preferred method for disruption; earned-value analysis of labour hours supports it; industry factor studies are a weaker substitute. Extended field-office overhead is normally proved by actual time-related costs, and head-office overhead by a formula approach argued from the evidence. Total cost and modified total cost claims, which simply attribute the whole overrun to the owner, are received with deep suspicion and only succeed where the four traditional preconditions are met. Underneath all of it lies the real determinant of success: contemporaneous records — the accepted baseline, statused monthly updates, daily reports, manpower and equipment returns, survey and quantity records, correspondence and minutes.
