An NEC4 ECC Option C contract has been let at essentially zero value and when works require undertaking a PMI is given and CE raised. Following the raising of a PMI and associated CE to undertake a scheme the contractor has provided a price for these works.
Upon undertaking these works some design changes occured and a further PMI and CE given which has added some scope.
The planned Completion date in the Accepted
Programme is far out as the contractor is allowing for upcoming schemes to be added once instructed so there is always no impact on planned Completion.
How should preliminary costs be captured if there’s no impact to planned Completion but there has been an impact to the length of time required on one of the sites instructed? I assume this is still classed as an effect to Defined Cost and therefore should be included rather than there’s no impact to planned Completion and therefore prelims won’t increase?
