The BBC is seeking to establish a roster of non-exclusive Framework Agreements for the integration and installation of new and refurbished broadcast production facilities. Systems integrators' responsibilities will vary from project to project; these include project planning, detailed design, installation, cabling, performance and acceptance testing and supply of equipment. The requirement will be broken down into 4 lots where services may be required by any area of the BBC; video, audio and central technical areas, as well a fourth lot mainly geared towards temporary production facilities at domestic and overseas sites for major sporting events.
