Factual and Procedural Background
This opinion concerns the interpretation and application of clause 13.8 and related provisions in a construction contract between the pursuers and the defenders. The dispute centers on the obligations of the defenders under clause 13.8.1 regarding architect's instructions, the consequences of non-compliance under clause 13.8.5, and related issues of extensions of time and liquidated damages for delay in completion of works. The defenders raised multiple lines of defence contesting the application and effect of clause 13.8. The pursuers challenged these defences and advanced preliminary submissions on contract construction and the nature of clause 13.8. The matter involves consideration of contractual interpretation, penalty clauses, implied terms, and procedural issues arising from an adjudicator's earlier decision awarding an extension of time.
Legal Issues Presented
- Whether clause 13.8.5 constitutes a penalty clause and is therefore unenforceable.
- What triggers the obligation under clause 13.8.1—specifically, whether the contractor must actually form the opinion that an architect's instruction will require adjustment to the contract sum or delay completion.
- The circumstances in which clause 13.8.1 does not apply, including instructions for expenditure of provisional sums, late instructions, and the architect's duty under clause 25.3.3.
- Whether implied terms exist obliging the pursuers and the architect not to hinder the defenders in complying with clause 13.8.1, and the effect of any breach of those implied terms.
- Whether the pursuers have acquiesced in, waived, or are personally barred from relying on the defenders' alleged failure to comply with clause 13.8.1.
- The effect of the adjudicator's decision on the burden of proof in subsequent court proceedings.
Arguments of the Parties
Pursuers' Arguments
- The contract must be construed as a whole, giving effect to all provisions, with special conditions prevailing over standard terms if conflicts arise.
- Clause 13.8 is designed to allocate the risk of delay costs arising from architect's instructions, requiring the contractor to notify the architect if an instruction would delay completion or require adjustment to the contract sum.
- Clause 13.8.5 is not a penalty clause but a legitimate contractual provision reallocating risk; failure to comply with clause 13.8.1 means the contractor bears the risk of delay without entitlement to an extension of time.
- The contractor is obliged to apply its mind upon receipt of an architect's instruction to whether it will cause delay or require adjustment; failure to do so cannot excuse non-compliance.
- Clause 13.8 applies to all architect's instructions, including those for expenditure of provisional sums and late instructions, except where delay is caused solely by late receipt of the instruction or supply failures by the pursuers.
- The architect's power under clause 25.3.3 must be read subject to clause 13.8.5, meaning failure to comply with clause 13.8.1 disentitles the contractor to any extension of time under clause 25.3.
- There is no waiver, acquiescence, or personal bar by the pursuers regarding compliance with clause 13.8.1, as the conduct relied upon is consistent with retention of rights and the architect had no authority to waive contractual terms.
- The adjudicator's decision awarding an extension of time does not affect the burden of proof in court proceedings, which remains on the defenders to justify the extension sought.
Defenders' Arguments
- Clause 13.8.1 only applies if the contractor actually forms the opinion that an instruction requires adjustment or delay; absence of such opinion negates the obligation.
- Clause 13.8.5 is a penalty clause because it imposes liability unrelated to actual loss caused by breach of clause 13.8.1 and penalizes procedural non-compliance rather than substantive delay responsibility.
- Clause 13.8.1 does not apply to instructions for expenditure of provisional sums, late instructions causing delay due to timing rather than content, or affect the architect's duty under clause 25.3.3.
- There are implied terms that the pursuers and architect must not hinder the defenders' compliance with clause 13.8.1, and failure to comply by the pursuers or architect may excuse the defenders' non-compliance.
- The pursuers have acquiesced in or waived compliance with clause 13.8.1, or are personally barred from relying on non-compliance, due to conduct including acceptance of work and delay notices without reference to clause 13.8.
- The adjudicator's decision awarding an extension of time shifts the burden of proof to the pursuers to show the extension was unjustified during court proceedings.

Court's Reasoning and Analysis
The court began by examining the nature and purpose of clause 13.8, situating it within the contract's broader scheme for managing delay and liquidated damages. Clause 13.8 imposes obligations on the contractor (defenders) to notify the architect if an instruction will cause delay or require adjustment to the contract sum, enabling the architect to reconsider the instruction and potentially avoid or mitigate delay.
On the penalty clause issue, the court applied established principles requiring (a) a breach of contract and (b) a sum payable that is unconscionable or punitive rather than a genuine pre-estimate of loss. It found that clause 13.8.5 is triggered by breach of clause 13.8.1 and thus relates to breach of contract. However, the liquidated damages sum (30,000 per week) is a genuine pre-estimate of loss for delay, not a penalty for breach of clause 13.8.1. The clause reallocates risk and preserves the employer's entitlement to damages rather than imposing a punitive sum. Therefore, clause 13.8.5 is not a penalty clause.
The court then addressed the triggering of clause 13.8.1, rejecting the defenders' literal construction that the obligation arises only if the contractor actually forms an opinion that delay or adjustment will result. The court held that the contractor is obliged to apply his mind to the instruction to form such a view, as a matter of commercial common sense and to give effect to the clause's purpose.
Regarding exclusions from clause 13.8.1, the court held that the clause applies to all architect's instructions, including those for provisional sums, unless the instruction relates solely to delay caused by late receipt or supply failures by the pursuers. The architect's duty under clause 25.3.3 is subject to clause 13.8.5, meaning non-compliance with clause 13.8.1 removes entitlement to extensions of time under all parts of clause 25.3.
On implied terms, the court found the defenders' averments relevant and suitable for proof before answer, acknowledging established authority that such terms may be implied to give business efficacy and reflect parties' presumed intentions. The court noted mutuality of obligations and that whether the defenders can rely on failure by pursuers or architect to comply with implied terms is a matter for evidence.
On acquiescence, waiver, and personal bar, the court accepted the legal principles cited by the pursuers but concluded that the defenders' averments raised issues that should be remitted for proof before answer. The court recognized overlap among the concepts and the factual nature of their application.
Finally, the court considered the adjudicator's decision awarding an extension of time and held that it does not affect the legal burden of proof in court proceedings, which remains on the defenders to justify the extension sought. The adjudicator's decision is binding only until final determination of the dispute.
Holding and Implications
The court's final decision was to:
- Exclude from probation the averments in answer 8(i) and 8(ii) concerning the penalty clause and the triggering of clause 13.8.1 on the basis that the defenders failed to aver formation of the requisite opinion.
- Exclude from probation the first and fourth sentences of answer 8(iii) but admit the second and third sentences concerning the applicability of clause 13.8.1 to instructions for provisional sums and related matters.
- Admit to probation the averments in answer 8(iv) and 8(v) relating to implied terms and acquiescence, waiver, and personal bar, remitting these issues to proof before answer.
The court proposed to discuss further procedural steps before allowing proof before answer.
Implications: The decision clarifies the construction of clause 13.8 and confirms that clause 13.8.5 is not a penalty clause but a legitimate contractual risk allocation mechanism. It affirms the contractor's obligation to actively consider architect's instructions and the consequences of non-compliance. The ruling on implied terms and waiver/acquiescence issues leaves factual disputes to be resolved at proof. The adjudicator's decision remains binding but does not shift the burden of proof in litigation. No new precedent beyond the immediate contractual interpretation and procedural rulings was established.
