You will gain an understanding of the key processes both leading up to contract award and then how to administer the contract for the duration of the project. Attendees of this course will have a much clearer understanding of the intent of the specific contractual clauses and in practical terms begin to see how they should administer them for the benefit of all parties on a particular project.

In the case of Option A, this comprises the total of the prices (that is the lump sum prices in the activity schedule) for those activities or groups of activities that have been completed by the relevant assessment date. This means any work done that is not part of a completed activity does not get paid for in that payment cycle. [...] Following completion, Option C provides for the project manager to compare the contractor’s tendered total of the prices with the total price for the works. This assessment is finalised for the final amount due. This results in the identification of ‘pain’ if the price for works done to date is greater or ‘gain’ if it falls under the tendered total of the prices. Option C then provides for how that gain or pain is allocated between the parties based on percentage shares (and ranges) set out in the contract data. This pain/gain mechanism is intended to incentivise the contractor to meet or better the target cost.\n\n### Option E",
