CAR / EAR & Builder’s Risk

Supply delays relating to some of the turbine jackets were alleged to have resulted in a critical delay to the project. CCi was appointed to determine the true criticality of the delay event. Using a combination of ‘but for’ and windows-based time slice analysis, CCi identified significant levels of float and flexibility within the project’s scheduled sequence, which could not be determined through the claimant’s preferred delay methodology, and ultimately led to agreement that no critical delay would likely be experienced and that no claim would be presented.

It was claimed that seven separate events had caused critical delay to the project’s completion date. CCi was appointed as the critical path expert to benchmark the project’s pre-incident status and levels of available float, and to advise as to the expected impact of the events. CCi’s critical path analysis ultimately demonstrated that due to the management of activity relationships, criticality was artificially imposed upon certain areas. Following a recalibration of activity relationships, it was agreed that the events had had no impact.

A series of incidents concerning a Tunnel Boring Machine (TBM) with a diameter of 13.7m, were claimed to have caused delay to the critical path of the project. CCi was appointed as the independent delay analyst to objectively separate delay resulting from damage, from that attributable to defect rectification and general project delays. Utilising a collapsed as-built method of analysis, CCi successfully demonstrated that the TBM incidents had not actually impacted the project’s progress.
