On average, equipment delivery was 3 months later than the agreed contractual delivery dates.
The longest delay in equipment delivery was for a component of the Sag Mill at 194 days and the Ball Mill Pinion Shaft at 193 days.

Several equipment were supplied with deficiencies. Examples:Minor deficiency: faulty welds on Conveyor AssemblyMajor deficiency: Overcast discharge head sections in the Ball MillOut of 107 delivered Equipment, 30 had some sort of deficiency.
Civil & Structural Deficiencies:Works by others were delivered with construction errors on many occasions, namely the Anchorages of the Sole Plates.

QuestionsMajor Problems9AccessAccess to work area was not ready for the Mechanical Contractor on many occasions, the most significant are summarized below:
Civil and Structures contractors were late on delivering installation areas or works required by the Mechanical Contractor. Delays were carried on by the Mechanical Contractor. Co-activity in work areas was not properly managed by the Engineer.

Steps done in this method :
Importing Primavera files for all areas and filter to Critical pathFind actual start and finish dates of all critical activities from daily log and Equipment deliveryInserting these dates into software month by month in order to cover all parallel delays and their impactsCalculating the difference between As-planned finish date of project and Impacted finish date of project by each activity in critical pathFinally, calculating all impacted days of delay

Original Contract value, including Contractor profit, is $2,549,130. Terminated Contract value is $1,814,598.
According to Clause 6.3.3 of contract, the contractor has the right to claim the loss of profit for the difference between the contract price and the earned amount.
For a profit of 5% Profit loss = 5% x ($2,549,130 $1,814,598) = 5% x $734,532 Claimable profit loss = $36,727
