Factual and Procedural Background
The Plaintiff, an employer, and the Defendant, a contractor, entered into a contract in late 1998 for the construction of a hotel at a location in The City. The contract incorporated the Standard Form of Building Contract (Private Edition with Quantities) (1980 edition) along with numerous additional provisions, including an Abstract of Conditions and a Schedule of Amendments. The contractual completion date was set for 25 January 1999, with liquidated and ascertained damages fixed at £30,000 per week for delay beyond this date until practical completion.
Initially, the architect was Company A, who also served as structural and mechanical and electrical engineer. On 2 December 1998, Company A was dismissed and replaced by Company B as contract architect, with separate engineers appointed for structural and mechanical and electrical roles.
Disputes arose concerning extensions of time. An adjudicator determined the Defendant was entitled to a five-week extension and ordered repayment of £150,000 by the Plaintiff. However, this adjudication was not binding, and the present proceedings address the matter afresh. The Plaintiff contends no extension beyond the contractual date is due, while the Defendant claims entitlement to an 11-week extension.
The Plaintiff initiated the current action seeking declaratory relief regarding the Completion Date and other remedies. The case proceeded through preliminary hearings addressing contractual interpretation, notably clause 13.8, with the court clarifying its scope. The present opinion sets out to analyze the contractual provisions, evidence, and legal principles to resolve the extension of time dispute and related claims for loss and expense.
Legal Issues Presented
- Whether the Defendant is entitled to an extension of time beyond the original contractual Completion Date under the terms of the contract.
- The proper construction and application of clause 13.8 concerning late instructions and their effect on extensions of time and contract sum adjustments.
- The extent to which concurrent causes of delay, including those attributable to the Defendant and those attributable to the Plaintiff or architect instructions, affect entitlement to extensions of time.
- The correct approach to the architect’s discretion in granting extensions of time under clauses 24 and 25 of the contract.
- The Defendant’s entitlement to loss and expense arising from architect’s instructions and variations.
Arguments of the Parties
Plaintiff's Arguments
- The Defendant is not entitled to any extension of time beyond the original contractual Completion Date.
- For entitlement to an extension, the Defendant must prove the delay was caused by a relevant event and not by pre-existing or concurrent delays for which the Defendant is responsible.
- Variations instructed during an existing delay do not absolve the Defendant from responsibility for pre-existing delays unless the delay resulted from the variation.
- The Plaintiff contends that delays claimed by the Defendant were not on the critical path and thus did not cause delay to completion.
- The Plaintiff relies on a narrow interpretation of clause 13.8, limiting its application to late instructions that cause adjustments due to their content rather than their lateness.
Defendant's Arguments
- The Defendant claims entitlement to an 11-week extension of time based on various architect's instructions and delays caused thereby.
- The Defendant relies on clause 25 to justify extensions for delays caused by relevant events, including compliance with architect’s instructions and late receipt of necessary instructions.
- The Defendant argues that concurrent causes of delay (both contractor and non-contractor risk events) entitle it to an extension proportionate to the delay caused by relevant events.
- The Defendant claims entitlement to loss and expense under clause 26 for delays materially affecting progress due to architect’s instructions and variations.
- The Defendant challenges the Plaintiff’s critical path analysis, asserting that certain roof steelwork and cladding works were critical and delayed completion.

Court's Reasoning and Analysis
The court began by setting out the contractual framework, focusing on clauses 24 and 25, which regulate completion dates, liquidated damages, and extensions of time. The court emphasized the importance of these clauses in allocating risk between the parties, protecting the contractor from liquidated damages for delays caused by employer-related events or other relevant events beyond the contractor’s control.
The court reviewed authoritative case law, notably Percy Bilton and Peak Construction, to affirm that liquidated damages clauses are strictly construed and do not apply if the employer or their agents cause delay. The court also relied on Balfour Beatty and Henry Boot to explain how concurrent causes of delay should be handled, concluding that the architect has a broad discretion to grant extensions based on what is fair and reasonable, even if delays arise from concurrent contractor and non-contractor causes.
The court rejected the Plaintiff’s proposition that only a single dominant cause of delay should be considered, instead endorsing an approach where concurrent causes are assessed and extensions granted proportionally. The court noted that delays caused by variations or late instructions must be assessed in light of their impact on the critical path and overall completion date, recognizing that causation in construction delay is complex and often intertwined.
In interpreting clause 13.8, the court noted prior rulings limiting its scope to late instructions that require adjustments due to their content rather than mere lateness. The court also addressed the timing for issuing instructions, concluding that the contractual completion date is generally the relevant benchmark for determining whether instructions were given in due time, balancing the interests of both parties and the contractor’s obligation to complete on time.
The court considered expert evidence on critical path analyses, with some criticisms raised about the accuracy of logic links and the identification of critical tasks. The court accepted that the roof steelwork and cladding were critical activities and that late instructions in this regard caused delay, entitling the Defendant to an extension.
Overall, the court applied a nuanced, fact-sensitive approach, emphasizing fairness and reasonableness in the exercise of the architect’s discretion and the court’s assessment of concurrent delay causes, consistent with the contractual scheme.
Holding and Implications
The court held that the Defendant is entitled to an extension of time for delay caused by certain architect’s instructions, including those relating to roof steelwork and cladding. This extension acknowledges that relevant events caused critical delays beyond the contractual completion date.
The Defendant’s claim for an extension of time is upheld in part, resulting in an adjustment of the Completion Date accordingly.
The decision directly affects the parties by modifying the contractual completion date and the calculation of liquidated damages. No new legal precedent was established; rather, the court applied existing principles of contract interpretation and causation in construction delay cases to the facts.
