The form of contract decides how you get paid, what happens when work changes, and how disputes are resolved. This guide explains the contract types used in Pakistan - from FIDIC forms to PEC templates - and the clauses that matter most to contractors and engineers.
Different forms shift risk in different directions. Know what each one asks of you before you sign.
The construction contract form for civil and building works where the employer (or their consultants) designs the works and the Engineer administers the contract. Used on many public and international projects in Pakistan.
Yellow covers plant and design-build where the contractor designs the works. Silver is EPC and turnkey, where the contractor takes on most of the scope and risk. Fewer mechanisms for claims than the Red Book.
The Pakistan Engineering Council publishes standard contract forms used on many domestic public and private projects. Familiar terms, but the specific edition and conditions of contract must be checked.
The most common private form: a BOQ with unit rates, re-measured as work proceeds and paid through running bills. Clear measurement rules and rates for every item are what make this form workable.
A fixed price for a defined scope. Simple to administer, but every change, omission or ambiguity becomes a variation question. The scope definition and exclusions must be watertight.
In practice many contracts are a mix of FIDIC clauses, PEC conditions and a borrowed BOQ. The documents rarely agree. Always check which conditions take precedence - it is usually stated in the particular conditions.
Every contract is really a set of payment and risk rules. These are the ones most disputes come from.
Monthly measurement, valuation and an Interim Payment Certificate issued by the Engineer, then payment within the period in the contract. Missed certificates and late payments are common triggers for claims.
Retention (often 5-10%) is held from payments and returned after completion and defects liability. Mobilization advances are usually secured by bank guarantees and recovered through deductions.
Instructed changes should be confirmed in writing and priced - usually by applying BOQ rates, agreed rates, or reasonable rates with rate analysis. Un-instructed changes become disputes.
Delay events that are not your responsibility entitle you to an extension of time and relief from delay damages - if you give notice within the contract period and keep the evidence. See the EOT and delay analysis guide.
Know whether you are re-measured against a BOQ or paid a fixed lump sum. Re-measurement needs clean measurement records; lump sum needs a crystal-clear scope. Your BOQ and rate analysis sets the baseline either way.
Most contracts start with the Engineer's decision, then negotiation, mediation or expert determination, then arbitration before the courts. Each stage has notice periods - keep them on a calendar.
Public-sector construction in Pakistan sits under two sets of rules that private projects do not have.
The Pakistan Engineering Council registers engineering professionals, consultants and contractors in defined categories. To bid on regulated and public-sector works, a contractor must be registered in the appropriate category and keep the registration valid. The registration category caps the value and type of work you can take on.
The Public Procurement Regulatory Authority rules govern how federal procuring entities advertise, evaluate and award contracts for goods, works and services. The core principle: open competition, transparent evaluation, and award to the lowest evaluated responsive bidder.
A weak or non-compliant tender is rejected on technical grounds before price is even compared. Getting the BOQ and documents right is not optional on public work.
Disputes are decided on records, not memory. Keep a complete, dated and signed file from day one.
The signed contract, all annexes, addenda, correspondence and the conditions of contract in the order of precedence stated.
The approved programme, updates, progress reports and records of actual start and finish against the plan - the basis of delay analysis.
Site instructions, variation orders, notice letters and minutes of meetings with the client, Engineer and consultants.
Daily diaries, attendance sheets, material records, dated photographs and weather records. Simple records, done daily, are the most valuable.
Measurement sheets, running and final bills, IPCs, rate analyses and payment records - see the contractor billing and IPC guide.
All letters and emails, kept in order and summarized in a chronology. If it is not in writing, it is hard to prove.
A step-by-step walkthrough of an Extension of Time (EOT) claim in the Pakistan contracting context - what you need, in what order, and how to make it stick.
Find the EOT clause in your contract (FIDIC, PEC Standard Form, or bespoke) and read the notice and submission timelines carefully. Entitlement starts with a clause - not with common sense.
EOT clauses usually require a written notice within a fixed period (often 14-28 days) of the delaying event. Late notice can forfeit entitlement even when the delay is genuine.
Record every event that delayed the critical work - late drawings, site handover delay, design changes, utility shifting, rain beyond the norm, or instructed variations.
An EOT is about delays to the critical path. Show how each event pushed completion, not just that the site was busy. A simple programme (bar chart) is often enough at board level.
Daily reports, site diary, inspection records, photographs, measurement sheets, and correspondence with dates. Contemporary records carry far more weight than memories.
Show the as-planned programme against the as-built position and the period of delay caused. Keep the arithmetic simple and traceable - every day claimed must be explained.
Distinguish time (EOT) from money. Entitlement to time must be proven first; prolongation cost (site overheads, staff, plant) is a separate head and needs its own supporting evidence.
Rejections usually cite late notice, no critical-path link, unsubstantiated records, or events caused by the contractor's own default. Address each head of rejection in the submission.
Pakistan practice: on PEC and PPRA-governed public work, the Engineer administers the claim on a time-barred basis - so the notice discipline above is not optional.
Use the Contractor Claim Template to structure the submission, and the Daily Site Report to keep the record trail.

FIDIC forms are international standard contracts published by the International Federation of Consulting Engineers, widely used on public and international projects in Pakistan. PEC forms are templates published by the Pakistan Engineering Council for domestic work. Both define payment, variation, time and dispute rules; the choice depends on the client and the project.
On most contract forms the Engineer, acting as the contract administrator, reviews the contractor's monthly measurement and valuation and issues an Interim Payment Certificate (IPC). The client then pays the certified amount within the payment period set out in the contract.
Instructed changes should be confirmed in writing as variations so they can be priced and paid. If work is changed without instructions, it usually becomes a dispute about whether the change was instructed, the rate to be applied and the time impact. Written records are the protection.
The Public Procurement Regulatory Authority (PPRA) rules govern how federal public-sector procuring entities buy goods, works and services in Pakistan. They require open advertised tendering, clear technical and financial evaluation, and award to the lowest evaluated responsive bidder.
Most contracts require the dispute to go to the Engineer's decision first, then negotiation or mediation before arbitration or the courts. You do not need a lawyer for the technical and documentary stages, but legal representation is normally needed for arbitration or court proceedings. Struc-Arch prepares the technical record and works with your lawyer.
