- 24. 25 The Engineer -Generally ■ The Engineer is a quasi arbitrator and has two functions, namely: ■ Agency function, where s/he administers the Contract on behalf of the Employer ■ Decision making function, where s/he certifies time and money ■ When in the agency function, the Engineer must not misapply or misunderstand the Contract ■ When in the decision making function the Engineer must be independent and fair to both the Employer and the Contractor ■ Over certification by the Engineer is negligence ■ The Engineer has no duty of care to the Contractor 25

- 36. 37 Unliquidated or generaldamages Employer breaches: • interference and prevention • late supply of information • failure to give possession Result of Employer breaches is Contractor’s claims for: •delay • disruption • prolongation • extension to the Time for Completion • additional payment In summary, the Contractor’s remedy for an Employer’s breach is recovery of general or unliquidated damages. (Note: Unliquidated damages are assessed after the breach)
- 37. 38 Liquidated damages Liquidated isa word recognised in the Shorter Oxford Dictionary and from as early as 1574 and is defined as ‘ascertained and fixed’ Questions that arise with respect to liquidated damages: • Are they an exclusive remedy for a breach? • an agreed price to be paid for a breach or non performance • Is an agreed price for a breach a penalty? • is the liquidated damage disproportionate to the loss? • Can the parties agree any price they wish? • freedom of contract –v- penalty • What is a genuine pre-estimate of loss? • is a genuine precise pre estimate impossible to determine? •What is the purpose of liquidated damages? • from Contractor’s perspective it takes away uncertainty and provides an incentive to perform • for Employer, the burden of proving actual loss
- 38. 39 Middle East (FIDICdelay damages –v- Liquidated damages) Qatar • Arabic term for liquidated is fines • principle of ‘freedom of contract is endorsed • principle of ‘good faith’ and bound by terms agreed • pre estimates of liquidated damages are permitted • no distinction between penalties and liquidated damages • FIDIC delay damages replaces liquidated damages • a genuine pre estimate is an important concept • exhaustive remedy depends on drafting • adjustment if no loss is incurred • superseding or contributory fault reduces compensation • liquidated damages provide certainty in contract • liquidated damages are uncertain in law due to exceptions and circumstances A guide to liquidated and ascertained damages for the Qatar construction sector, Warren L, Hall A (2013), Clyde & Co
- 39. 40 Middle East (FIDICdelay damages –v- Liquidated damages) United Arab Emirates Construction contracts provide for: • pre determined amount of damages to be paid by Contractor for late completion of a project • liquidated damages are an incentive for the contractor to perform • liquidated damages removes the burden of ascertaining loss The Courts have determined: • liquidated damages is a secondary obligation • delay fines in contracts are a penalty clause and a secondary obligation • termination is fatal to liquidated damages • liquidated damages are an estimate and actual loss is preferred • no loss then liquidated damages should be repudiated • the application of liquidated damages is subjective and prone to the application of exceptions Liquidated damages under UAE and UK law, a comparison (2014), Ibrahim A, Mullen J, Fenwick Elliot
- 40. 41 Middle East (FIDICdelay damages –v- Liquidated damages) Sultanate of Oman Royal Decree No. 29/2013 enacting the Civil Code issues such as liquidated damages relating to building contracts (Muqawala) is codified as follows: • if the subject matter of obligation is not a sum of money, the contracting parties may determine the amount of compensation in advance by making provision of same in the contract or in a subsequent agreement • In all cases, the court may, upon application of either of the parties amend such agreement to make the compensation equal to the damage , and any agreement to the contrary shall be null and void Result : • courts may award liquidated damages • liquidated damages must be a reasonable assessment of the loss • Court may reopen liquidated damages and award general damages Construction Disputes in Oman – Here and Now (2013), Curtis, Mallet – Prevost, Colt & Mosie LLP
- 41. 42 Summary (FIDIC delaydamages –v- Liquidated damages) Principles surrounding liquidated damages : • freedom of contract is acceptable practice • parties free to agree liquidated damages • liquidated damages must be reasonable estimate • liquidated damages can be reopened by the courts • liquidated damages may fall away and be substituted by general damages Conclusion: In respect of the application of liquidated damages in the Middle East there is no such thing as certainty
