Kuwait's construction market runs on two legal tracks that every project file must reconcile: the Civil Code issued by Decree-Law No. 67 of 1980, whose contract-for-works (muqawala) rules govern the private relationship between employer, contractor and designer, and Public Tenders Law No. 49 of 2016, which governs how government bodies procure works through the Central Agency for Public Tenders. Most commercial contracts are built on FIDIC forms, but the statutory overlay decides which clauses hold. This article reads the framework from the perspective that decides disputes: notices, changes and payment records.
The framework: Civil Code, Tenders Law and FIDIC practice
The Civil Code, Decree-Law No. 67 of 1980, supplies the default law of every Kuwaiti construction contract: formation, performance, delay, force majeure, defects and liability. It applies whether or not the contract mentions it, and several of its provisions cannot be contracted around. Public and semi-public procurement adds Law No. 49 of 2016, which channels tenders above the thresholds through the Central Agency for Public Tenders, sets bid and performance security, controls variation orders and price adjustment, and protects national industry.
In practice, employers issue FIDIC-based contracts, commonly the Red Book for build-only works, and the statutory rules sit underneath. The result is a hierarchy that project teams should write down at kickoff: the signed contract and its particular conditions first, then the Civil Code where the contract is silent or cannot derogate, then the Tenders Law where the employer is a public authority. Disputes are lost by teams that discover this hierarchy during the claim rather than at the start.
Public procurement: security, validity and award under Law No. 49 of 2016
The Tenders Law disciplines the front end of every public contract. Article 45 requires each bid to carry the initial deposit, the bid bond, by certified check or bank guarantee from a bank authorized in Kuwait, unrestricted and in favor of the Agency; bids without it are disregarded even if technically acceptable. Article 46 fixes bid validity and requires bidders to extend validity, with the bond renewed, when asked; refusal means exclusion. After award, Article 65 obliges the successful bidder to submit the final security, the performance bond, within the notified window: failure within one month of notification allows the authority to treat the bidder as withdrawn, extendable once for a similar period.
Two further controls shape public variations. Article 74 forbids the contracting authority from issuing variation orders whose non-compulsory total exceeds five percent of the contract value, up or down, without the consent of the Agency's Board, sought within one month with a reasoned memorandum and the supervising authority's opinion. Article 75 permits price modification for major materials only through a price-adjustment equation stated in the tender documents and the contract, presented to the Agency for approval. Public employers and contractors should map these approvals into the change procedure before the first variation arises.
Foreign contractors: market access and the local-content rules
Foreign participation has historically run through Kuwaiti agents, but amendments to Article 24 of the Commercial Code and Article 31 of the Public Tenders Law opened a more direct role for foreign construction companies, subject to the applicable exemptions and registrations. On major projects the structure is usually a joint venture or consortium pairing the foreign specialist with a Kuwaiti contractor of the right classification, and the choice between agency, branch and joint venture should be made with the tax, licensing and bid-eligibility analysis in one view.
For public awards, Article 87 of the Tenders Law adds two local-content obligations that belong in the execution plan, not the fine print: the foreign contractor must purchase not less than twenty percent from local products and ten percent from products and services of small and medium enterprises, or from locally registered suppliers if unavailable, evidenced by certified receipts, and must subcontract not less than thirty percent of the awarded works to local contractors registered and classified with the Agency or the Kuwait Municipality. The Council of Ministers may adjust these percentages by resolution. We see compliance built into procurement schedules from day one succeed, and retrofitted explanations fail.
Price and scope: Articles 689 and 690 of the Civil Code
Kuwaiti law draws a sharp line between lump-sum and remeasurement contracts, and the line is statutory. Under Article 690 of the Civil Code, a contractor on a fixed lump-sum contract cannot demand a price increase, even where the construction plan is modified or added to, unless the change results from the employer's fault or was expressly authorized by the employer. Lump-sum bidders therefore carry design-development risk that FIDIC users from other jurisdictions do not always expect, and the bid review should price it.
Under Article 689, on remeasurement contracts priced against an estimated bill of quantities, the contractor who realizes during execution that a significant overrun of the estimate will be necessary must promptly inform the employer; silence forfeits the right to claim the increase. This is a statutory notice duty with a forfeiture sanction, and it belongs on the project notice register alongside the contractual notice clauses. Our standing advice: treat every emerging cost signal as a potential Article 689 event and notify early, in writing, with quantities.
Changes and instructions: building the record that wins
Variations are where Kuwaiti project files live or die. The contractual machinery (instruction, valuation, approval status) must run in parallel with the statutory controls: the five percent Board-consent line of Article 74 for public contracts, and the Article 690 authorization analysis for lump-sum work. Each variation should carry a number, the source instruction, scope, measure, price basis, program effect and approval status, and agreed work should be separated from disputed work on the payment application rather than blended.
The evidence standard is contemporaneity. Date instructions, requests, approvals, photographs, delivery records and progress reports while the work happens; a schedule alone proves little if site access was never given or drawings were never released. Maintain one issued-drawing register with revisions and transmittal dates, and pair the baseline program with actual access and permit dates. When a dispute reaches an expert or a tribunal years later, these records are the case.
Delay: Article 293, extensions and concurrency
Delay liability starts from Article 293 of the Civil Code: where performance of an obligation becomes impossible or delayed, the debtor must compensate the resulting damage unless it establishes that non-performance or delay was due to a cause beyond its control. The burden sits on the delaying party to prove the external cause, which is why the critical-path program and the cause-by-cause record matter more than the correspondence volume.
Extensions of time follow the contractual procedure: Kuwaiti practice typically requires the contractor's request to be answered within thirty or forty-five days, and FIDIC-based forms layer their own notice windows on top. Where several causes run together (access, design, suppliers, weather), separate them on an updated critical path; a global claim that blends employer delay with contractor delay invites the tribunal to dismiss it. Record each notice in the form and time the contract requires, and keep the dated program version that proves the effect.
Force majeure: Articles 214, 215, 437 and 295
The Civil Code gives force majeure a hard edge that surprises foreign contractors. Articles 214 and 215 provide that where performance becomes impossible due to an external cause beyond the performing party's control, the obligation is extinguished and the contract is automatically revoked. Article 437 confirms the obligation is extinguished when the debtor proves impossibility from an external cause, and Kuwaiti case law adds that the event must be unforeseeable. Automatic revocation is a blunter outcome than the relief most FIDIC forms contemplate, which is why the force majeure clause deserves real drafting attention in Kuwait.
Article 295 supplies the drafting room: the parties may agree that the obligor bears liability even for cas fortuit and force majeure, and, by the same logic, they may allocate the consequences of an excusable event (suspension, extension, cost sharing) instead of accepting revocation. Kuwaiti courts apply the statutory criteria of externality, unforeseeability, unavoidability and impossibility, so the clause should define events, notice, mitigation and consequences expressly. We review this clause on every Kuwait contract we touch.
Payment: certification, delay compensation and the subcontractor position
Payment practice runs on certification: periodic or milestone certificates issued by the engineer or project manager after inspection, consistent with the Civil Code's treatment of the price of works under Article 677. When the employer pays late, Article 110 of the Commercial Code entitles the contractor to compensation for delayed payment where the contract fixes a payment timeframe; the claim needs the certificate, the due date and the arrears record, not a narrative.
Subcontractors hold two statutory protections worth planning around. The Civil Code gives subcontractors a direct claim against the employer, limited to what the employer owes the main contractor, when the main contractor fails to pay, and Article 1081 grants contractors and engineers who erect, reconstruct, repair or maintain buildings a privilege over the works to the extent of the increase in the immovable's value. Employers should route payment through certified applications and obtain subcontractor releases; subcontractors should document their claims as they accrue.
Defects and the decennial liability: Articles 692 to 697
Kuwaiti decennial liability is statutory and cannot be excluded for what it covers. Under Articles 692 to 697 of the Civil Code, the contractor and the supervising designer are jointly liable for total or partial collapse and for any defect threatening the strength and safety of a building or fixed installation, for ten years, with the claim subject to a three-year period from collapse or discovery of the defect. The liability attaches by operation of law, independent of the negotiated defects liability period.
Contractual defect regimes sit alongside, not instead of, the decennial rule. The typical defects liability period obliges the contractor to remedy notified defects, and handover certificates should record reservations item by item, because a certificate or a payment does not settle open defects or variations. At completion we advise employers to assign an owner for each test, defect, as-built record, warranty and final-account item, and contractors to keep the site records that rebut alleged defects; both sides should calendar the decennial horizon and the insurance that responds to it.
Testing, completion and takeover
Completion is a process with statutory shadows. FIDIC-inspired practice in Kuwait commonly requires tests on completion to be run by the engineer within a defined window after notification, fourteen days in Red Book practice, and takeover then passes custody and maintenance responsibility. The Civil Code obliges the contractor to deliver work conforming to the contract and trade usage, and the employer's duty to cooperate and accept conforming work frames the takeover meeting.
The record that matters at takeover is the reservations list. Acceptance with recorded reservations preserves claims; acceptance without them invites argument that defects were waived, subject always to the non-excludable decennial liability for structural safety. Prepare the handover file as a closing audit: tests passed, snagging closed or reserved, as-builts delivered, retention and warranty terms stated, and a dated list of matters that survive handover. This file is the starting point for both the maintenance period and any later dispute.
Claims hygiene: the project file that survives
Across Kuwaiti projects, the winning side is usually the side with the better baseline. One version of the contract, drawings, scope, access plan, program and payment terms, with named instruction authority and a drawing register, prevents the evidentiary drift that kills claims. Notices should be checked against the real workflow at kickoff, not rediscovered after the dispute, and every notice should cite its clause, state the event and reserve the time and cost effect.
Disputes themselves typically move through contractual engineer determinations and amicable stages toward arbitration or the Kuwaiti courts, and public-contract disputes carry the Tenders Law context, including the approved variation ceiling and price-adjustment records. Whatever the forum, the same file serves: baseline, notices, programs, certificates, correspondence and reservations. Build it as you build the works, and the dispute clause becomes a venue choice rather than a gamble.
What we review on a Kuwait construction project
When our office in Kuwait reviews a construction or infrastructure project, we start with the hierarchy: contract conditions against the Civil Code's non-excludable rules, and, for public work, against the Tenders Law's security, variation and price-adjustment controls in Articles 45, 65, 74 and 75. We test the notice register against Articles 689 and 293, the force majeure clause against Articles 214, 215, 437 and 295, payment and subcontract protections against Article 110 of the Commercial Code and the Civil Code's direct-claim and privilege rules, and completion files against the decennial liability of Articles 692 to 697. The deliverable is a claims-ready record protocol, not a memo: registers, notice templates, approval routes and the evidence each future claim will need.

Frequently asked questions
Which law governs a construction contract in Kuwait?
The Civil Code issued by Decree-Law No. 67 of 1980 governs the contractual relationship, including its contract-for-works provisions; public procurement adds Public Tenders Law No. 49 of 2016 administered by the Central Agency for Public Tenders.
Can a lump-sum contractor claim more money when the design changes?
Under Article 690 of the Civil Code, no, not even for plan modifications or additions, unless the change results from the employer's fault or was expressly authorized by the employer; authorization should be documented before the work proceeds.
What must a contractor do when costs overrun a remeasurement estimate?
Article 689 of the Civil Code requires prompt notice to the employer once a significant overrun becomes evident during execution; failing to notify forfeits the right to claim the increase.
What security do public tenders in Kuwait require?
Article 45 of the Tenders Law requires a bid bond by certified check or Kuwaiti bank guarantee, without which the bid is disregarded, and Article 65 requires the performance bond after award, failing which within one month of notification the bidder may be treated as withdrawn.
Are there local-content duties for foreign contractors on public projects?
Yes. Article 87 of the Tenders Law requires foreign contractors to purchase at least twenty percent from local products and ten percent from small and medium enterprise products and services, or from registered local suppliers if unavailable, and to subcontract at least thirty percent of the works to registered local contractors, adjustable by Council of Ministers resolution.
How does Kuwaiti law treat force majeure?
Articles 214 and 215 of the Civil Code extinguish the obligation and revoke the contract when performance becomes impossible from an external cause, Article 437 confirms extinguishment on proven impossibility, case law requires unforeseeability, and Article 295 lets parties reallocate the risk by agreement, so drafting matters.
How long does construction defect liability last in Kuwait?
Under Articles 692 to 697 of the Civil Code, the contractor and the supervising designer are jointly liable for ten years for collapse and defects threatening structural strength and safety, with claims subject to a three-year period from collapse or discovery.
