BATNA Development in Construction Disputes
Understanding BATNA in Construction Context
BATNA — Best Alternative to a Negotiated Agreement — is your fallback position if negotiations fail. In construction, a weak BATNA means you negotiate from desperation; a strong BATNA gives you confidence and leverage.
Developing Your BATNA
Step 1: Identify All Alternatives
If a contractor is negotiating a variation claim with the employer, alternatives might include:
Filing a formal claim under FIDIC Clause 20, Referring the dispute to a Dispute Adjudication Board (DAB), Suspending works under FIDIC Clause 16.1 (if employer defaults), Proceeding to arbitration, Accepting a reduced settlement, and Walking away and terminating the contract (Clause 16.2).
Step 2: Evaluate Each Alternative
For each alternative, assess:
Cost: Legal fees, time, relationship damage, cash flow impact, Probability of success: Based on contract terms, evidence, precedent, Time: How long until resolution? DAB might take 84 days; arbitration 12-24 months, and Reputation impact: Will this affect future bids and relationships?.
Step 3: Select the Best Alternative
Rank alternatives by expected value (probability x outcome). The highest expected value becomes your BATNA.
Example: A $500,000 variation claim
Arbitration: 70% chance of full recovery, $100K legal cost, 18 months = expected value $250K, DAB: 80% chance of 80% recovery, $30K cost, 3 months = expected value $290K, and Settle at $350K now: 100% certain = $350K.
In this case, settling at $350K is better than the BATNA (DAB at $290K expected value), so the negotiation zone favours settlement.
Improving Your BATNA
Strengthen documentation: Better records = stronger claim = better BATNA, Build coalitions: Subcontractors, suppliers, other stakeholders may strengthen your position, Develop alternative suppliers: If negotiating with a sole-source supplier, develop second-source capability, Seek expert opinions: Independent engineer or QS assessment adds credibility, and Prepare legal groundwork: Ensure contractual notices are properly served.
Reservation Price and ZOPA
Reservation Price: The worst outcome you will accept — below this, you walk to your BATNA, ZOPA (Zone of Possible Agreement): The overlap between your reservation price and the other party's reservation price, and If no ZOPA exists, no agreement is possible — you must exercise your BATNA.
Common BATNA Mistakes in Construction
Overestimating BATNA: "I will win in arbitration" — without assessing legal costs, time, and risk, Underestimating opponent's BATNA: The employer may have stronger alternatives than you think, Ignoring relationship costs: A litigated dispute may win money but lose future contracts, Failing to improve BATNA before negotiating: Accepting a weak position because alternatives were not developed, and Revealing BATNA too early: Disclosing your fallback weakens negotiation power.
