Paper format. 16-Civ-B8 Management of Construction, National Exams December 2017. Three hours, closed book, one approved calculator (Casio or Sharp). Six questions of equal value (20 marks each); any five constitute a complete paper, and only the first five presented in the answer book are marked. All six are solved here, because this set is a study resource rather than an examination script.

Delay-related claims arise wherever the time actually taken to perform the work exceeds the time the contract allowed, and someone other than the party bearing the loss is arguably responsible for the difference. The recurring causes fall into a small number of families. Owner-caused delay is the largest: late or incomplete design information, late issue of instructions and shop-drawing reviews, restricted or late access to the site, owner-supplied materials or permits that do not arrive, and interference by the owner's other contractors. Changes are the second family — not merely the direct cost of added work, but the schedule and productivity consequences of introducing it, which is where the disproportion between a small change order and a large claim usually originates. Differing site conditions, particularly subsurface and existing-structure conditions on rehabilitation work, form a third. Neutral events such as abnormal weather, labour disputes and force majeure form a fourth, and are typically excusable but not compensable. Finally, contractor-caused delay — understaffing, poor procurement, defective work requiring rework, subcontractor default — is inexcusable, and its presence alongside an owner-caused delay creates the concurrency that makes these disputes so difficult.
The contractual modifications that reduce claims work by removing the ambiguity that claims feed on. The most effective is a complete and coordinated design before tender, since the majority of claims originate in documents that were priced before they were finished. Beyond that: a realistic contract period supported by an owner-reviewed baseline schedule submitted and accepted early; an express requirement to maintain and update that schedule monthly, with the updates becoming contract records; a notice provision with a short, clearly stated period and a stated consequence, so that delay events are identified while the facts are still recoverable; a time-impact analysis requirement obliging the contractor to demonstrate the effect of an event on the current schedule before an extension is granted; explicit allocation of weather risk against a defined baseline of normal conditions; a differing-site-conditions clause that shares geotechnical risk rather than disclaiming the owner's own borehole data; agreed rates or a formula for extended overhead and equipment standby, which converts the most contentious head of claim into arithmetic; and a defined dispute-resolution ladder. CCDC 2 does much of this: Part 6 deals with changes, delay and claims for extension of contract time, and the notice periods in GC 6.5 and GC 6.6 are strict. A no-damages-for-delay clause is a blunter modification; Canadian courts read such clauses narrowly and will not enforce them against an owner's own bad faith or wilful interference, so it shifts rather than removes the dispute.
Settlement approaches form a ladder of increasing cost, formality and loss of control. Negotiation between the project participants settles the great majority of claims and is almost always the cheapest outcome. Where the parties are close but stuck, partnering and standing dispute-review boards resolve issues in real time, before positions harden and before the delay has been fully suffered. Mediation introduces a neutral facilitator without decision-making power; CCDC 2 GC 8.2 requires the parties to attempt mediation under the CCDC 40 rules before arbitration, and CCDC 40 also provides for a project mediator appointed at the outset. Adjudication — now statutory in Ontario and being adopted in other provinces through prompt-payment legislation — delivers a binding interim determination within a matter of weeks, so that cash keeps flowing while the merits are finally resolved later. Arbitration under CCDC 40 gives a binding award from a decision maker the parties can choose for construction expertise, with limited appeal rights and a private record. Litigation is the residual: public, slow, expensive, and decided by a judge without specialist construction training, but with full discovery and appeal rights and the only route where third parties must be joined.
Validating a claim requires four distinct analyses, and a claim that fails any of them fails altogether. The first is entitlement: identifying the contractual or legal basis, confirming that notice was given as required, and establishing that the event is one whose risk the contract assigns to the other party. The second is causation through schedule analysis, which is the technical heart of the exercise. The recognised methods, set out in AACE RP 29R-03 and the Society of Construction Law Delay and Disruption Protocol, divide into prospective methods (impacted as-planned, and time-impact analysis, which inserts a fragnet for the event into the schedule update current at the time and measures the movement of the completion date) and retrospective methods (as-planned versus as-built, collapsed as-built or “but-for”, and windows or contemporaneous period analysis, which slices the project into periods and identifies what actually drove the critical path in each). Windows analysis is generally preferred where reliable schedule updates exist, because it follows the critical path as it genuinely shifted rather than assuming a single static path. The third is concurrency and criticality: an owner-caused delay that runs in parallel with an inexcusable contractor delay ordinarily yields an extension of time but no compensation, and a delay to an activity with float is not a project delay at all until the float is exhausted. The fourth is quantum: extended field overhead priced from actual records, extended head-office overhead by an agreed formula or by proof of unabsorbed overhead, equipment standby at agreed idle rates, escalation, and lost productivity — the last best proved by a measured-mile comparison of an unimpacted period of the same work against the impacted period, since industry inefficiency factors carry far less evidential weight. Underpinning all four is the contemporaneous record: daily reports, manpower and equipment returns, correspondence, minutes, photographs and the schedule updates themselves. A well-documented average claim generally recovers more than a poorly documented strong one.
