Choosing the Contract Form for a Saudi Build: A Structured Selection

A selection process that picks a construction contract form from the state of your design and your appetite for risk, instead of defaulting to whatever the last project used.

The contract form is a decision about who carries which uncertainty, and it should be made after you know how complete your design is and how much change you expect. A fully designed villa and a refurbishment of an occupied building cannot sensibly sit under the same form. The sequence below moves from information to risk allocation to a signed document, and it keeps the commercial logic visible at every step.

Before stage one

You are ready to start this selection when you know three things: how much of the design will be finished before anyone prices the work, who inside your organisation can authorise a change, and whether your funding is fixed or can absorb movement. If any of those three are still open, the selection will be a guess dressed as a decision. Regulations and standard forms in this area are revised from time to time, so confirm the current position before you commit to a form.

• Write down the percentage of design information that will exist at tender, by discipline, not as a single number.
• List the parts of the works where the scope genuinely cannot be fixed yet, such as below ground conditions or tenant requirements.
• Record who signs a variation and what value threshold sends it upward for approval.
• State whether the funding line is a hard ceiling or a forecast with headroom.
• Identify the person who will administer the contract day to day once it is signed.

Stage 1: Map the uncertainty before you look at any form

List every part of the works where the final quantity, specification or method is not yet known, and mark each as an unknown of design, of ground, of regulation or of your own decision making. Design unknowns can be closed by spending more time on drawings. Ground unknowns are closed by investigation. Your own decision unknowns are the most expensive because they arrive after the contractor has mobilised. The map tells you whether a fixed price is realistic or a fiction.

• Deliverable: A one page uncertainty map with each item classified and an owner named against it.
• Owner: The project lead, with input from the designer and the cost adviser.
• Approval gate: No form is discussed until every item on the map has a classification.

Stage 2: Decide what you are buying: a price, a service or an outcome

A lump sum buys a price for defined work. A cost reimbursable arrangement buys a service and visibility over the actual spend. A design and build arrangement buys an outcome against performance requirements. The question is not which is cheapest in theory but which matches the information you hold. Buying a price when you cannot define the work produces a low tender followed by a stream of claims, and buying a service when the work is fully defined means paying for transparency you did not need.

• Deliverable: A written statement of the commercial intent in two or three sentences.
• Owner: The owner or the board member who carries the budget.
• Approval gate: The statement is agreed before any pricing document is drafted.

Stage 3: Test the candidate forms against your map

Take three or four realistic candidates and run your uncertainty map through each. For every item, write what the form does with it: whether the risk sits with the contractor, with you, or in a shared mechanism such as a provisional sum or a target cost. Where a form leaves an item with the contractor and the contractor cannot reasonably price it, expect either an inflated allowance or a dispute later. This test is dull and it is the single most useful hour in the whole process.

• Deliverable: A matrix of uncertainty items against candidate forms, with the allocation written in plain words.
• Owner: The cost adviser or commercial manager.
• Approval gate: Every row has an allocation and no row reads as unclear.

Stage 4: Price the risk you intend to transfer

Transferring risk is not free. A contractor asked to carry ground conditions, currency movement on imported materials or regulatory change will price that exposure, and you pay for it whether or not the risk occurs. Estimate what each transfer is likely to add, compare it with the cost of carrying the risk yourself and keeping a contingency, and decide deliberately. Some transfers are worth a premium because they protect a funding covenant or an opening date. Others are simply expensive insurance against something you could manage.

• Deliverable: A short risk pricing note that states which transfers you will pay for and why.
• Owner: The commercial manager, signed off by the budget holder.
• Approval gate: The contingency you retain is sized against the risks you decided to keep.

Stage 5: Draft the particular conditions that make the form fit

Standard forms are written for a general case and are then tuned by the particular conditions. This is where payment periods, the valuation mechanism, notice requirements, the authority of the engineer, the security package and the dispute route are set. Amendments should be few, specific and drafted by someone who understands how the clauses interact, because a change to one clause often disables another. The wording of these conditions is a legal question, so the final drafting belongs with a licensed Saudi legal adviser rather than with the project team.

• Deliverable: A marked up set of particular conditions with a reason recorded against each amendment.
• Owner: Legal counsel, instructed by the commercial manager.
• Approval gate: Each amendment has a written justification and no clause is edited without checking its cross references.

Stage 6: Build the pricing document that matches the form

The form and the pricing document have to agree. A lump sum with a bill of quantities behaves differently from a lump sum with an activity schedule, because the first gives you measured rates for valuing change and the second does not. A remeasured arrangement needs a complete method of measurement stated in the documents. A target cost needs a defined cost definition and a share mechanism. Mismatches here surface at the first variation, when nobody can agree what rate applies.

• Deliverable: A pricing document, a stated method of measurement and a defined basis for valuing change.
• Owner: The cost adviser.
• Approval gate: A test variation is valued on paper using the documents as drafted, and the answer is unambiguous.

Stage 7: Sanity check the administration burden

Every form imposes work on you as well as on the contractor. Cost reimbursable arrangements need open book auditing. Remeasured arrangements need monthly joint measurement on site. Target cost arrangements need an agreed cost ledger. If you do not have the people to do that work, the mechanism will drift into informality and you will lose the protection you paid for. Match the form to the team you actually have, not the team you intend to recruit.

• Deliverable: A named administration plan listing who performs each recurring contractual duty.
• Owner: The project lead.
• Approval gate: Every recurring duty in the contract has a named person and a frequency.

Stage 8: Confirm the fit with your funder and insurer

Lenders and insurers have views on contract form. A funder may require a fixed price and a performance security before releasing a facility, and an insurer will ask about the allocation of design responsibility. Put the proposed form and the security package in front of both before you go to tender, because changing form after bids are received wastes the whole exercise. If a bank requirement conflicts with the form you chose, resolve it in writing rather than assuming it will be waived.

• Deliverable: Written confirmation from the funder and the insurance broker that the proposed structure is acceptable.
• Owner: The budget holder.
• Approval gate: No tender is issued until both confirmations are on file.

Handovers between stages

The handover that fails most often is between the person who chose the form and the person who administers it. Whoever signed off the risk allocation should spend an hour walking the contract administrator through the uncertainty map, the reasoning behind each amendment and the mechanism for valuing change. Without that conversation the administrator applies the clauses literally and misses the commercial intent, which is how an owner ends up conceding a claim that the drafting was designed to prevent.

How you know it is finished

The selection is finished when you can explain, in one page and without referring to a standard form by name, who carries each significant uncertainty on the project and what happens when it occurs. If your explanation relies on the phrase that the contractor takes care of it, the work is not finished. Keep the uncertainty map and the risk pricing note in the contract file, because they are the record of intent that a later reader will need when the first serious claim arrives.
