Firstly, the Contract Programme should be status updated in accordance with the frequency described in the Contract. If the Contract is silent regarding the frequency of status updates, then updates of at least monthly intervals, and also as at the time a claimed delay event occurring, are generally adequate to maintaining a contemporaneous critical path and more accurate forecast on completion. However, the more frequent the status, the more accurate the as-built data recorded as part of the statusing process is likely to be, therefore weekly status recording and fortnightly status updates and rescheduling is considered best practice.

The critical path is a defined term derived from the Critical Path Method that represents the calculation of the longest path through a project network diagram, or the shortest time in which a project can be completed. The critical path in a network diagram consists of activities all of which have zero days float.
It is possible for two or more paths through a network diagram to have zero days float and therefore each of these paths are on the critical path.

Distinguished from ‘delay allowance’/’buffer’ or ‘contingency’, float is the is the amount of time by which an activity can be delayed without delaying its successors (free float) or the project's completion (total float).
The responsibility for consumption of float will depend on the drafting of the contract with respect to programme management, float consumption, delay and acceleration.
The question relating to float ‘ownership’ generally refers to the question of whether the Contractor is entitled to an extension of time in a situation where they are forecasting to complete ahead of the Completion Date but are delayed in reaching this earlier finish date. The answer often depends on the drafting of the contract and more particularly the extension of time regime.
