It provides for the appointment of a consultant for an agreed period of time based on a priced task schedule and staff rates for different grades of staff. Prices on the task schedule are either a lump sum for that item, or may be carried out on a time basis. The consultant bears the risk of being able to perform the tasks at the agreed prices.
If the client wants the consultant to carry out services that are not on the task schedule, they are notified as compensation events (similar to relevant events on other forms of contract). This will result additional payment being made, priced using the compensation event assessment procedure.
