The Crown Commercial Service (CCS) schedule for the Technology Services 2 framework promised that intention-to-award notices were due to be sent to suppliers on 7 August, triggering a 10 day standstill period before the framework is awarded on 21 August.
A Cabinet Office spokesperson has promised the award notices are now on course to be sent this week but so far no one has received anything.
Technology Services 2 is the successor to the original Technology Services framework, which expired in May, and is estimated to be worth between £1 billion and £3 billion.
The framework will look after central and local government organisations and covers a range of IT services including hardware and software support, enterprise security and data management.
The four Lots included in the framework are: Technology Strategy and Services Design; Transition and Transformation; Operational Services; and Programmes and Large Projects.
The Cabinet Office spokesperson said the framework will go live this month.
