Under an ECC3 Option C contract, the Works Information contains a number of schedules which include quantities of work to undertake; an example is ducting and lets say it states there is 4,580KM of 100mm 4-way duct to install.
On review of the drawings and following a take-off of quants for procurement purposes, the Contractor finds that there is in fact 5,000KM of 100mm 4-way duct to install.
Would the Contractor be entitled to a Compensation Event for an additional 420m of ducting?
Potentially the Contractor could raise a notification under Clause 17.1 of an ambiguity or inconsistency between the documents and dependent of the response, any subsequent change to Works Information to resolve the ambiguity or inconsistency would be a Compensation Event and which further to Clause 63.8 would be assessed most favorable to the Contractor.
This example opens up a wider question on what is the impact of stating quantities within the Works Information albeit clearly an Option C contract is not remeasurable?
