Liquidated / Delay Damages

Delay amount with the contractual cap. Sub-Clause 8.8.

Interim Payment (IPC)

Amount due this period: retention, advance, previously certified. Clause 14.

DAAB & dispute timeline

Dispute deadlines: DAAB decision (84 d), NOD (28 d), amicable settlement. Clause 21.

EOT & delay

Revised completion date with EOT and the remaining delay for delay damages.

Time-bar (28 / 84 days)

Event date → notice and claim deadlines and time-bar risk. Sub-Clause 20.2.

FIDIC calculations are rarely difficult arithmetically. The difficulty lies elsewhere: which date starts the clock, whether a given amount belongs in the base, and which cap applies. These calculators take the arithmetic away so you can concentrate on the contested part — justifying the inputs.

Each calculator works on the standard conditions of the FIDIC 2017 editions. A project’s Particular Conditions can change periods, rates and caps, so the result is a starting point for checking the contract rather than a substitute for it.

Which calculator, when

  • An event has occurred that may found a claimTime-bar (28 / 84 days) — the same day
  • The Engineer has granted or refused an extension of timeEOT & delay
  • The Employer is proposing to deduct for late completionLiquidated / Delay Damages — check the cap
  • You are preparing or reviewing a payment applicationInterim Payment (IPC)
  • A dispute has been referred to the DAABDAAB timeline — watch the NOD deadline

How to use the result

These are reference calculations. Before building a claim, tender or dispute position on them, check the periods, rates and caps against your project’s Contract Data and Particular Conditions, and against the requirements of the governing law.
