What I know that in NEC contract family is the trick in activities total float of each , so if we could make the activities which are by others (e.g. Provided by the owner) with minimum float and the activity under your scope at maximum float .
Often in NEC contracts family the contractor schedule completion date earlier than approved one , the duration between the planned and the agreed one can be considered as a project total float , if the contractor could finish at the earlier ,ok fine.
But in case of fault so, the contractor will be entitled to project total float since the contractor come first .
My regards.

Just to clarify, Terminal float is not the same as buffer / TRA.
TRA is, or should be, an allowance to account for schedule risk, made against a specific activity within the programme asssociated with that risk. It is represented either by a seperate activity linked using FS(0), or by an increase duration of the at-risk activity. If the latter, the amount of TRA incoroprated within the activity duration should be clearly noted, either is a seperate column, or activity description. TRA can only be eaten up by the contractor to mitigate against delay, not by the client.
Terminal float is basically total float. i.e difference between the last activity to complete and the contractual completion date. Because all the float belongs to the contractor, the terminal float value remains constant when Compensation Events are applied to the programme, and the cotnract end date moves acoordingly. (NB: beware of the effects of differing calendars when applying these CEs)
When reviewing tender schedules, try and get TRA applied (though in my experieince you may struggle), and be aware that its a lot easier for the contractual date to be moved back throughout the life of the project than in most other forms of contract.

NEC run workshops for NEC3 programming which will tell you all you need to know.
It only costs about £250 and you get a copy of the contract too.
Check out their website.
As others have said, Time Risk Allowance can be added as a custom field to highlight the amount of buffer each task has in terms of duration.
Another thing to note is that when a CE is agreed that it should be appplied to the latest agreed version of the programme, as NEC3 makes no mention of EVM and baseline schedules.
Time Risk Allowance (TRA) should be clearly displayed on the approved programme. You could ask for the same on tender programmes, but dont hold your breath.
Be aware that under NEC, all the float at the end of the project most definitely belongs to the contractor. If the project completion date is a must hit, consider buying some of this float off the sucessful tenderer.
NEC contracts place a greater emphasis on programming than most other contract forms, and specify a level of detail for the approved programme which you could try and apply to tender phase. Other than TRA, the major one is probably that the programme should show methodology, erquipment & resources planned for all site activities.
