Principled Negotiation in Construction Contracts
The Harvard Method: Fisher and Ury Framework
Principled negotiation, developed by Roger Fisher and William Ury at the Harvard Negotiation Project, provides a structured approach that is particularly powerful in construction contract negotiations where relationships must be maintained despite adversarial positions.
The Four Principles
1. Separate the People from the Problem
In construction, disputes often become personal. A contractor may feel the consultant is unfairly rejecting work, while the consultant believes the contractor is cutting corners. The key is to address the issue — not attack the person.
Recognise that every negotiator has two interests: the substance (the claim, the variation, the delay) and the relationship (future work, reputation, trust), Be hard on the problem, soft on the people, In FIDIC contracts, the Engineer must separate personal opinions from contract provisions, and Use role clarity: "As the Engineer, I must apply Clause 13.3 — this is not personal".
2. Focus on Interests, Not Positions
A contractor's position might be "I demand a 30-day extension." The underlying interest could be: avoiding liquidated damages, maintaining workforce, or recovering from a delay caused by the employer's late design issue.
Identify interests by asking "Why?" repeatedly until you reach the core need, Common interests in construction: completing the project, maintaining cash flow, preserving reputation, avoiding disputes, Shared interests form the basis of agreement — both parties want the project completed, and Conflicting interests are traded — the contractor gets time; the employer gets quality assurance.
3. Generate Options for Mutual Gain
Construction negotiations often deadlock because parties see only one solution. Brainstorming expands the pie before dividing it.
Set aside a dedicated brainstorming session separate from formal negotiation, Use techniques: "What if we..." scenarios, expert consultation, precedent analysis, Example: Instead of arguing over delay costs, explore acceleration options, schedule re-sequencing, or partial handover, and Consider package deals: bundle multiple issues so each party gains on some and concedes on others.
4. Use Objective Criteria
In construction, objective criteria are abundant: contract clauses, standards (BS, ASTM, ISO), market rates, industry benchmarks, and expert determinations.
Frame each issue as a search for objective standards, Example: "Let us use the FIDIC Clause 8.4 framework to evaluate extension entitlement", Use independent quantity surveyor assessments for variation pricing, Refer to published indices for material price escalation, and Never yield to pressure — only to principle.
Application in Construction
When negotiating a variation under FIDIC Clause 13, the principled approach means:
Do not attack the contractor's pricing — examine the basis (market rates, actual costs), Identify shared interest: fair compensation for legitimate work, Generate options: lump sum, remeasurement, cost-plus, schedule of rates, and Apply objective criteria: published rate guides, previous similar work, independent QS assessment.
Common Pitfalls
Treating negotiation as a zero-sum game when mutual gains are possible, Letting emotions drive decisions when contract provisions should govern, Failing to prepare BATNA before entering negotiation, and Accepting positional bargaining when principled approaches would yield better outcomes.
