Dear Experts
Project Scenario - 80% Planned duration surpassed , contractor providing further structural design changes to Sub-contract(**MEP) with existing delay events from contractor i.e ( late civil clearance, civil rework impact and pending approval for delivarables)
Please advise which is the better Delay claim methodology to implement in this type of scenario : As planned + As impacted OR as-built vs as impacted OR Window analysis ( P6 : Approved Baseline or Recovery programme (-) total set of delay events impacting = total duration required to complete overall project)
**Note : My client is MEP subcontractor
