How to Control Scope, Cost and Time in GCC Construction
·16 min read
Key Takeaways
You do not trade scope against cost and time in a meeting; you trade them through notices, instructions, and certificates.
Saudi Arabia's new Government Tenders and Procurement Law lifts the permitted contract increase from 10% to 20%.
Article 224 is a mandatory hardship provision, which means any clause in your contract that tries to exclude or limit the court's power under it is void.
Under Sub-Clause 20.2.1 of the FIDIC 2017 forms, a party claiming additional time or payment must notify the engineer as soon as practicable and no later than 28 days after becoming aware of the event.
A programme that models three summer seasons and three Ramadans is a programme you can defend.

New Saudi ceiling on instructed contract additions
Two pieces of law changed the arithmetic on Gulf construction projects this year. The UAE's new Civil Transactions Law came into force on 1 June 2026, and Saudi Arabia's Council of Ministers approved a replacement procurement law in early August. Both reach straight into the three things every site team argues about: scope, cost and time. Good GCC construction project management now depends as much on reading your contract correctly as on reading your programme. Here is how the three constraints actually behave in the Gulf, and what to do differently.
Why Scope, Cost and Time Behave Differently in the GCC
The triple constraint, restated for a giga-project
Every project manager learns the triple constraint early: move one of scope, cost, or time and at least one of the others has to move too. On a fit-out in Manchester, that trade-off is mostly a conversation. On a Gulf giga-project it is a contractual event with a deadline attached.
The reason is scale and structure. Analysis published by law firm King & Spalding in December 2025 put known, planned and unawarded project spending across the GCC at roughly US$3.1 trillion, with Saudi Arabia's pipeline alone near US$1.65 trillion and the UAE's close to US$875 billion. Programmes of that size run on heavily amended FIDIC forms, multi-tier subcontracts and public procurement rules that cap what the employer is even allowed to change.
So the honest version of the triple constraint in the Gulf is this: you do not trade scope against cost and time in a meeting; you trade them through notices, instructions and certificates. Miss the paperwork and the trade-off happens anyway, just not in your favour.
If you want the general discipline of spotting uncontrolled growth before it lands, that is covered separately in our guide to the fundamentals of scope creep control. This article picks up where that one stops, at the point the change becomes contractual.
Two 2026 rule changes that move the goalposts
Saudi Arabia's new Government Tenders and Procurement Law raises the ceiling on how much a government entity may add to a contract. Under the previous law, Article 69 allowed an increase of up to 10% of contract value and a decrease of up to 20%. The new law lifts the permitted increase to 20%. It takes effect 120 days after publication in the Official Gazette, and the implementing regulations will fill in the detail.
In the UAE, Federal Decree-Law No. 25 of 2025 replaced the old Civil Code from 1 June 2026. Contracts signed before that date stay under the old rules. Anything signed after sits under the new text, and two articles matter enormously to contractors.
Giga-project scale is what turns the triple constraint into a contractual event.
How to Control Scope, Cost and Time on a GCC Construction Project
1. Freeze a contractual baseline and get it accepted in writing, with the calendar, float, and sequence all visible.
2. Log every instruction the day it arrives, whether it is written, verbal, or a marked-up drawing.
3. Serve notice within 28 days of the event, before you know the full impact.
4. Price the variation before you build it, not after.
5. Keep the critical path live, updated monthly against the accepted baseline.
6. Certify and chase payment on the interim cycle, never in arrears.
7. Re-forecast cost and completion every month and tell the employer when a lever has to move.
That sequence is the whole method. The sections below explain why each step is worth more in the Gulf than almost anywhere else.
Scope: Variations, Not Scope Creep
What is a variation order under FIDIC?
A variation is a change to the works that the engineer or employer instructs under the contract. It is not the same as scope creep. Scope creep is unmanaged growth nobody paid for. A variation is a change the contract already anticipates, with a defined route to extra time, extra money, or both.
The distinction matters because it decides who carries the cost. Work done without an instruction is usually work done at your own expense. Work done under a proper variation is work you can price.
The Saudi change-order ceiling just moved
For public contracts in Saudi Arabia, the employer is not free to add unlimited scope. The procurement law sets a hard percentage limit, and the 2026 reform doubles the headroom on additions from 10% to 20%, while the reduction limit stays at 20%.
Here is the practical consequence, worked through. On a SAR 500 million public contract, the old rule capped instructed additions at SAR 50 million. The new ceiling allows SAR 100 million. That is a genuinely different risk picture for a contractor who priced preliminaries, plant and staff around the smaller number. The full text of the law is published by the Saudi Ministry of Finance.
The reform also cuts the Ministry of Finance's contract review window from 15 working days to four, and lifts the direct purchase threshold from SAR 100,000 to SAR 1 million. Faster approvals sound like good news. They also mean instructions can reach site quicker than your commercial team can price them.
Lump sum under the UAE's new Civil Transactions Law
UAE law has always been tough on lump-sum contractors. The principle carried over into the new code: a rise in material, labour or other costs does not on its own entitle you to a higher price. Build to the agreed drawings for the agreed sum and that is what you get.
What changed is the escape valve. Article 829(3) of the new law gives a court the power to extend the time for performance, adjust the contract price, or cancel the contract altogether where unforeseeable exceptional circumstances arise and the financial basis of the bargain collapses.
Article 224 sits alongside it and is stronger still. It is a mandatory hardship provision, which means any clause in your contract that tries to exclude or limit the court's power under it is void. You cannot draft it away.
The takeaway for a Gulf contractor is blunt. On a lump-sum job, a contractor who builds first and prices later is funding the change out of their own margin, and the new hardship route is a remedy for genuine economic collapse, not a substitute for serving a variation notice.
Time: The Notice Clock Decides Your Entitlement
What is the FIDIC 28-day notice rule?
Under Sub-Clause 20.2.1 of the FIDIC 2017 forms, a party claiming additional time or payment must notify the engineer as soon as practicable and no later than 28 days after becoming aware of the event. The notice is a condition precedent. Miss it, and the entitlement is gone, whatever the merits.
That is the single most expensive sentence in Gulf construction. A contractor can be completely right about a delay and still recover nothing because a notice went out on day 31.
The 84-day detailed claim
Notice is only the first gate. Sub-Clause 20.2.4 then requires a fully detailed claim, with contractual basis and supporting particulars, within 84 days of the claiming party becoming aware of the event. Fail on the detail and you can undermine the notice you served correctly.
Treat both clocks as programme activities, not legal chores. They belong in your monthly controls cycle with an owner's name against them. The scheduling side of this, including how baselines and delay evidence are held, is covered in our breakdown of Primavera P6 in GCC construction.
Concurrent delay: time without money
Concurrency is where Gulf claims usually get stuck. Two delays overlap, one your risk and one the employer's, and both sit on the critical path.
The typical outcome under FIDIC-based contracts is an extension of time for the employer-risk event, protecting you from liquidated damages, but no recovery of prolongation costs for the concurrent period. You keep your neck, not your money. Plan cash flow on that assumption rather than hoping for both.
Cost: Escalation, Certification and Cash
What is driving GCC cost escalation in 2026
Turner & Townsend's Global Construction Market Intelligence 2026, the seventeenth edition of the survey, gathered data from 112 markets across 44 countries in March 2026. It forecasts Middle East construction cost escalation reaching 5.1% by 2027, behind only Africa at 7.0% and ahead of Australia and New Zealand at 4.9%. The EU sits lowest at 2.8%.
Labour is the pressure point. The survey found shortages reported in roughly 71% of markets, and mechanical, electrical and plumbing trades were the worst hit, with shortages flagged in 87% of markets. Sovereign programmes in Saudi Arabia and the UAE are now competing for the same contractor pools that data centre and AI infrastructure projects are pulling from.
A fixed-price bid written on 2026 rates and delivered in 2028 is therefore carrying a real escalation gap. Either the contract has an indexation mechanism, or somebody absorbs it.
Cost control on a Gulf project is really cash control.
Interim payment certificates and the cash-flow gap
Cost control on a Gulf project is really cash control. The interim payment certificate cycle, from application through engineer's valuation to employer payment, is where projects quietly run out of working capital while still showing a healthy margin on paper.
Three habits help more than any software:
Submit applications on the contractual date every month, complete, with measurement backing.
Track certified value against applied value as a standing KPI, not an annual review.
Escalate an uncertified variation at the same speed you would escalate a safety issue.
The Saudi reform is relevant here too. It requires government entities to settle what they owe the private sector on time before taking on new commitments, which is a meaningful signal for supply-chain liquidity.
Building the Regional Calendar Into Your Baseline
This is the part global project management guides leave out entirely, and it is worth more days than most claims.
Summer midday work bans
The UAE runs an annual Occupational Heat Stress Prevention Policy, better known as the midday break. Outdoor work in direct sunlight is prohibited from 12:30 to 15:00 every day between 15 June and 15 September. The 2026 season was the twenty-second consecutive year it has been applied.
Penalties are real: AED 5,000 per worker found in breach, rising to a maximum of AED 50,000 where several workers are involved. Certain activities are exempt where stopping is unsafe or technically impossible, including concrete pouring, asphalt laying and emergency repairs to water and electricity supplies. Details are published by the UAE Ministry of Human Resources and Emiratisation.
Those exemptions are a planning tool, not a loophole. Sequencing pours into the restricted window, with the proper permits and welfare provision, is a legitimate way to protect the critical path. The wider compliance picture is set out in our guide to HSE legal requirements in the GCC.
Ramadan working hours
Ramadan shortens the working day by law, and the rules differ by country. In the UAE private sector, daily hours are reduced by two hours for all employees, regardless of religion or whether they are fasting. In Saudi Arabia, Muslim employees work a maximum of six hours a day or 36 hours a week.
Build both into the project calendar as a named calendar in your scheduling tool. A programme that models three summer seasons and three Ramadans is a programme you can defend. One that treats them as productivity loss is one you will argue about later.

When Something Has to Give: Choosing the Lever
At some point, a giga-project client will tell you the completion date is immovable. That is usually true, because it is tied to an event, a tenant, or a national target. So the other two levers have to move.
If the fixed constraint is...
Move this first
Get this in writing
Time (a hard opening date)
Cost, through acceleration or added resource
Instruction to accelerate, with agreed cost basis
Cost (a capped budget)
Scope, through descoping or phasing
Omission variation and revised completion date
Scope (a non-negotiable output)
Time, through an extension
EOT award before the date passes, not after
The rule underneath all three is the same. Name the lever, quantify it, and get the employer's agreement recorded before you act on it. Teams that can do this well are in short supply, and the delivery discipline behind it is set out in our guide to project controls in GCC construction and oil and gas. Sustainability obligations are increasingly arriving as late scope too, a pattern we cover in ESG targets on GCC mega projects.
Name the lever, quantify it, and record the employer's agreement before acting.
Frequently Asked Questions
It is the relationship between scope, cost, and time. Changing one forces a change in at least one other. On Gulf projects, the trade is made through contractual instructions and notices rather than informal agreement.
Sub-Clause 20.2.1 of the FIDIC 2017 forms requires notice as soon as practicable and within 28 days of becoming aware of the event. A fully detailed claim follows within 84 days under Sub-Clause 20.2.4.
Turner & Townsend's 2026 survey points to cost escalation reaching 5.1% by 2027 and acute labour shortages, with MEP trades short in 87% of markets. Late variations and uncertified work add to the gap.
Concurrent delay is when an employer-risk event and a contractor-risk event both delay completion. Under most FIDIC-based contracts, the contractor gets extra time but usually cannot recover prolongation costs for the overlapping period.
Under the previous law, the increase was capped at 10% of contract value. The new Government Tenders and Procurement Law approved in August 2026 raises that ceiling to 20%, with reductions still limited to 20%.
The Short Version
Scope, cost, and time are not really three separate problems in the Gulf. They are one problem seen from three angles, and the contract decides which angle you are allowed to argue from. Strong GCC construction project management comes down to a contractual baseline, disciplined notices inside 28 days, a calendar that already knows about heat bans and Ramadan, and a monthly re-forecast honest enough to say which lever needs to move.
The two 2026 law changes give Gulf contractors more room on scope in Saudi Arabia and a genuine hardship route in the UAE. Neither will help a team that files its notice on day 31.
