Client Dispute Trigger

The Feb 2026 update introduces a 45-day slip on project completion, exceeding the contract Clause 18.4 threshold of 21 days/month. The primary driver is the addition of PRT.088/089 (Dewatering System — 42 days) with no prior change order notification. This likely constitutes a variation under the contract. Client has 10 days to respond to the contractor's recovery plan request.

Required Actions

Owner's Representative actions required:

  • Issue Formal Schedule Non-Conformance Notice within 48 hours
  • Request contractor's Schedule Recovery Plan (SRP) within 14 days
  • Investigate CIV.188 deletion — active activity removed without notice
  • Evaluate EOT entitlement for PRT.088/089 scope addition
