FIDIC Claims

Preparation and substantiation of EOT, variation, and compliance claims under FIDIC forms — from first notice through to determination and DAB proceedings.

Forensic Delay Analysis

Evidence-driven critical path analysis — baseline vs. as-built comparison, delay event quantification, and disruption assessment to SCL Protocol principles.

Contract Administration

The day-to-day discipline of notices, records, and correspondence that keeps a contractual position intact — so an entitlement is never lost to a procedural defect.
