Extensions of time

Delays occur on most construction projects, and always have done. At some point during a project, particular parts of the works, or the works as a whole, will not progress as quickly as planned, with the risk that the contractual completion date will not be met.

This guidance note covers:
- costs of delay;
- background to extension of time clauses;
- delay assessments using BIM; and
- strengths and weaknesses of delay analysis methods.

This is part of the RICS QS and Construction Standards.

Please be aware that this guidance note contains some material which is in the process of being updated for revisions to the CDM Regulations, RIBA Plan of Work, and updates to the JCT, NEC and FIDIC suites. Members are made aware of these impending revisions in order that they first check the most up to date position before electing to act in accordance with this guidance document.
