Four working tools from our forensic scheduling and claims practice: time-extension cost, a delay classifier, all seven named delay-analysis methods on one schedule, and the Eichleay home-office overhead formula.
Time-extension cost estimator
A planning-level view of what a schedule extension adds to a contract.
Planning only. Entitlement to time or money, and the amount, depend on the contract and on a forensic analysis of the schedule record. That is what we do: talk to us.
Excusable, compensable, non-excusable, concurrent
List each delay event, who caused it, when it started, how long it lasted and how much float the activity had. The tool takes float into account, finds days where different parties overlap, classifies every day and totals the time and money.
| Delay event | Responsible party | Start day | Days | Float days | Notice |
|---|
Framework: an excusable delay is one the contractor is not responsible for; it is compensable when the owner caused it and non-compensable when neutral (such as unusually severe weather). A non-excusable delay is the contractor's. Only delay to the critical path counts, after float is used. Entitlement depends on your contract's notice, time-extension and no-damages-for-delay clauses and on the law of your jurisdiction. This is a teaching and planning tool, not legal advice or a claim.
One schedule, seven methods, seven answers
Enter your activities with logic ties, the baseline duration and the as-built duration. Where an activity ran longer than planned, choose who is responsible for the overrun. The tool runs a critical path calculation and then applies all seven named delay methods so you can see how the answer changes with the method.
| ID | Activity | Predecessors | Baseline days | As-built days | Overrun party |
|---|
The sample project is illustrative. Each activity's overrun is treated as one delay event assigned to one party; real analyses model many fragments, resource logic, calendars and progress-override choices. Different methods legitimately produce different allocations, and the rule for concurrent delay varies by contract and jurisdiction. This is a teaching and planning tool, not a delay analysis or legal advice.
Eichleay formula for unabsorbed overhead
When an owner-caused delay or suspension keeps a contractor on standby, home-office overhead that the delayed contract would have absorbed goes unrecovered. The Eichleay formula allocates a share of company overhead to the contract and turns it into a daily rate.
Eichleay is the federal formula for unabsorbed home-office overhead. Courts generally require proof that the delay was owner-caused, that the contractor was on standby (work stopped or substantially reduced and ready to resume on short notice) and that it could not take other work to absorb overhead. Classic Eichleay divides by actual days of performance, including the delay; the simple form divides by the contract period and produces a higher daily rate. Other methods (Allegheny, Carteret, fixed percentages) exist, and some states and contracts bar or limit home-office overhead claims or set a fixed markup. Do not claim both Eichleay and a percentage markup for the same overhead. This is a planning tool, not legal advice or a claim.
Need the real number, defended?
These are starting points. A simulation-based risk analysis or a forensic delay analysis gives you a figure you can defend to a board, an auditor or a dispute board.
