What is Delay Analysis?

Construction and engineering projects of any size and length invariably involve an acceptance that change will happen and there is a likelihood of unplanned change meaning that claims are often inevitable. Delay analysis is the process of analysing the project programme/ schedule, updates thereof and other contemporaneous records and forensically identifying and examining the cause of delay and its effect (or impact) on progress and completion of a project. Where the delay impacts on completion date of the project this is known as critical delay.

In addition to identifying the cause and effect of individual delays, issues such as delay to progress (e.g. due to disruption), the critical path, float, concurrent delay, acceleration and mitigation are often considered.

Many standard form contracts contain an ‘extension of time’ provision for events for which the contractor is excused and prevent the works being completed by the prevailing contract completion date. One of the goals of the extension of time provision and delay analysis is to ascertain the appropriate contractual entitlement to an extension of time.

Where the parties to the contract are unable to agree the extension of time, our independent expert using the delay analysis, opinion and report, is able to assist the Parties or Dispute Board; and more commonly, the tribunal (Adjudication, Arbitration, Litigation) in deciding the period of each and overall delay and the appropriate extension of time. Liability for the delay is a point to be decided by the tribunal.

With over 40 identified methods of analysis, in combination methodologies, Diales’ mission is to demystify the process.  Our experts find ways of presenting these complex arguments in a manner that is simple to understand and robust enough to withstand challenge.
