EOT for Rain and Utility Delay, and the Exposure to Liquidated Damages
A contract for a 25 km dual carriageway uses the PEC standard form, with a completion date of 30 June. The contractor claims 45 days of extension of time: 25 days for rain in February and March, and 20 days for delay in shifting a 132 kV transmission line crossing the alignment. Records from the nearest meteorological station show February-March rainfall was 20% above the ten-year average. The tender documents, however, contained a rainfall clause defining exceptionally adverse weather as more than 150% of the monthly average. The transmission line was not shown on the tender drawings. Shifting of utilities was within the employer's scope, and the contractor says it gave notice on 15 March. The engineer's interim payment certificate is ready, and the employer wants to apply liquidated damages at 0.1% per day, capped at 10%.
1. Assess the entitlement for each head of claim. What is your determination on the 45 days?

Rain claim - likely nil or close to nil. The contract defines the threshold, and 20% above average is nowhere near 150%. Ordinary and even moderately bad weather is priced risk that the contractor carries. The only route to entitlement is to show specific days on which rainfall, or its physical consequences on site, actually stopped work on the critical path, independent of the percentage comparison. Even then, the number of such days will be small, and the contractor must produce daily records - site diary, plant returns, photographs - not a monthly summary. On the facts given, I would allow nothing without that evidence, and perhaps a handful of days at most with it.
Utility claim - arguable. Shifting the 132 kV line was the employer's scope, so the employer owns the risk of that work being late. But the physical existence of a 132 kV line is visible to any contractor visiting the site, so the argument that it was unforeseeable is weak on existence; the strength of the claim lies in the timing and method, which the employer controlled. Entitlement depends on proving the delay was on the critical path and that notice was timely. Notice on 15 March is only valid if the contractor became aware of the delay on or after mid-February under a 28-day rule. If the delay began in January, the notice is late and the entitlement is at risk.
Determination: reject the 25 days for rain; allow the utility days that are proven critical, subject to notice.
2. How do you treat the interaction of the two events, and what does the contract require of the engineer?

Concurrency. If the rain-affected days fall inside the period when the utility delay was already blocking the critical path, the contractor was already delayed by the employer's risk and cannot recover the same days twice. The correct method is to build a time-impact analysis: identify the critical path at the time of each event, apply each event separately, and combine. Overlapping days count once. Where the contractor was in culpable delay on the critical path at the same time as an employer-risk event, the entitlement is further complicated and, in many forms of contract, reduced.
Engineer's duty. Under the PEC form the engineer must determine the claim, not simply pass it to the employer. That means: assess within the contractual period, give reasons in writing, state the EOT granted (or nil), and identify which records were relied on and which were missing. The engineer must also request further particulars where the claim is unsupported before determining. Failure to determine is itself a breach of the engineer's role and often the point at which disputes escalate.
Act independently. The engineer is paid by the employer but certifies under the contract. Determining nil on the rain claim and partial on the utility claim, with reasons, is the defensible position.
3. Can the employer apply liquidated damages? Set out the conditions and the calculation.

Threshold condition. Liquidated damages accrue only after the extended completion date. If EOT is granted for the utility delay, the completion date moves by that amount first, and LDs are calculated on the balance only. Applying LDs to the original 30 June date before determining the EOT would be premature and is a common ground for challenge.
Calculation. At 0.1% of the contract sum per day, capped at 10%. The cap is reached at 100 days of delay; beyond that, LDs stop accruing and the employer's remedy is termination or general damages, subject to the contract. Confirm which contract sum the percentage applies to - usually the accepted contract amount, excluding variations.
Validity. LDs must be a genuine pre-estimate of the employer's loss, not a penalty. A rate of 0.1% per day is within the range commonly accepted, but the employer should be able to explain how it was derived (additional supervision, price escalation, loss of toll revenue). If challenged and found to be a penalty, the clause is unenforceable and the employer must prove actual loss.
Procedural step. Issue a written notice of intention to claim LDs and deduct only through the payment certificate after the EOT determination is complete. Deducting first and justifying later reverses the burden and looks like bad faith.
