Dating bases guide


The usual practice now is to insert a date in the contract linked to the date of the return of tenders.

The FIDIC suite of standard conditions of contract (the Red Book and Yellow Book), set the base date at 28 days before the latest date for the submission of tender.

"English" indicates that the teaching will be held in English or a special course will be held in English for foreign students.

For example, in the Joint Contracts Tribunal (JCT) Design and Build Contract, the base date determines the allocation of risk in relation to changes in statutory regulations, changes to VAT exemptions and changes to definitions of dayworks.

Traditionally the base date was set as the date of tender, however this was sometimes found to give rise to uncertainty because of the complexity and duration of tendering procedures.

This may be done by setting a base date for specified items and defining the price indices by which fluctuations will be assessed.

Fluctuation may allow for; changes in taxation; changes in the cost of labour, transport and materials; and even changes in head office or administrative costs.

The JCT Design and Build Contract suggests a date that is 10 days prior to the date of the return of tenders.
