Assessing Schedule Delays

Methodology Overview

Assessing schedule delays in construction projects is a critical process that determines the root causes of time slippage and calculates their impact on the project completion date. This methodology provides field teams with a structured way to analyze critical path deviations, distinguish between excusable and non-excusable delays, and implement recovery actions before the project falls too far behind.

Key Implementation Steps

Implementing this methodology requires a systematic approach to identify variables, execute checks, and finalize site documentation.

The team identifies the specific delay event, gathers all daily logs, and examines the baseline schedule. We isolate the activities directly affected by the disruption, verifying their current status, actual start dates, and any dependencies that may trigger secondary delays across the site.

Using a fragnet analysis or time impact analysis (TIA), project managers model the delay within the current schedule. This helps determine whether the delay impacts the critical path and allows the team to draft recovery measures, such as re-sequencing tasks or introducing additional shifts.

The proposed recovery plan is reviewed with affected trades and subcontractors to ensure feasibility. Once agreed, the team updates the master schedule, documents the formal extension of time (EOT) request if applicable, and logs all decision records in the project archive.

Expected Results & Output

By applying this methodology, project teams can objectively quantify the time impact of any field disruption. This leads to clear responsibility assignment, minimizes disputes with owners and subcontractors, and provides a clear roadmap for recovery, ensuring the project target finish date remains achievable.
