Extension of Time Calculator (EOT)
Calculate Extension of Time entitlements for construction delays. Analyze delay events, float consumption, concurrent delays, and generate EOT claim summaries.

Notes:
- EOT entitlement based on SCL Delay Protocol principles
- Float is consumed before delays become critical
- Concurrent delays may require detailed window analysis
- Consult contract clauses for specific EOT provisions
- Document all delay events contemporaneously

About This Calculator
This Extension of Time (EOT) Calculator helps contractors and consultants analyze delay events and calculate time entitlements per FIDIC contract provisions. Evaluate excusable delays, assess float consumption, identify concurrent delays, and generate substantiated EOT claims. Essential for contract management in UAE and Gulf construction projects where delays often arise from weather, late instructions, or unforeseen conditions.
When to Use This Calculator
- Analyzing project delays for EOT claims
- Determining impact of employer-caused delays
- Evaluating weather delays against contract provisions
- Assessing concurrent delay situations
- Preparing substantiated EOT submissions
How to Use This Calculator
Enter baseline dates
Input original contract start, completion, and key milestone dates
Log delay events
Record each delay with start date, duration, and cause category
Classify delay type
Categorize as excusable, compensable, or contractor risk
Assess float impact
Determine if delay consumed float or impacted critical path
Generate EOT calculation
Review entitled days considering concurrency and float
Typical Scenarios in UAE & Gulf Projects
45 days lost to exceptional weather events (sandstorms, rain) during facade installation. Calculator compares actual weather days against 10-year UAE climate data, identifies 32 days exceeding normal allowances, and generates EOT claim with meteorological evidence.
Critical path delayed 60 days awaiting design approval from consultant. Concurrent contractor delay of 15 days for late material delivery. Calculator applies time-impact analysis showing 45 days net EOT entitlement (60 - 15 concurrency offset).
