§ Mr. Kirkwood
I have been asked to reply.1280W
Figures are not kept in a form which allows the cost of establishing the PDVN to be identified. However, set-up costs were identified in the First Report of the Information Committee of Session 1993–94, "The Provision of a Parliamentary Data and Video Network". The cost of hardware and network software over the period 1994 to 2000 was estimated to be £1,962,000 (at 1994 prices). The hardware and network software was subject to a significant upgrade during the summer recess of 1999, at a cost of £2,100,000.
Cabling of the Parliamentary Estate is a continuing project and is necessary not just for the installation of the PDVN but also for the introduction of a new fire detection system. Identifying cabling costs specific to the installation of the PDVN is thus not possible.
The contract for maintenance of the PDVN currently costs £600,000 a year and includes the replacement of equipment and minor upgrades to the software. The cost of parliamentary staff directly involved in the day-to-day maintenance of the Network is approximately £100,000 a year.
