Transport for London (TfL) is tendering a technical testing, analysis and consultancy services framework contract worth up to £15m over four years.

TfL envisages signing up up to 20 suppliers for 11 lots of work. The agency wants to procure technology consultancy services to meet the requirements of its Traffic Directorate (TD), its Technology Services Group (TSG) within the Bus Performance Directorate, and the Congestion Charging and Traffic Enforcement Directorate (CC and TE).

As part of the procurement TfL wants traffic modelling specialists, intelligent transport systems specialists - including CCTV areas, specialist traffic control engineering services, design and implementation support for traffic signal schemes, traffic project management services, and telecoms specialists in fixed and mobile wireless control management.

In addition, TfL wants erasable programmable read-only memory (EPROMS) traffic signal controllers, GIS CAD services, systems engineering and systems integration support, business process analysis and engineering, and real time transport data statistical analysis support.

TfL says the value of the work will be between £4m and £15m, and interested parties have until 8 February to apply to tender.

At the end of last year it became known that TfL was keen to bring some competition and innovation into two major contracts worth up to £1bn it had with IBM.

A TfL market testing excercise is covering two IT systems for London’s Congestion Charging and Low Emission Zone schemes, and the penalty charge notice processing for civil traffic enforcement contraventions.

IBM’s contract to run the systems comes up for renewal in October 2014, and could be extended for up to a further five years, but TfL wants to assess what new technologies are available in the market and whether a different supplier could ensure better value for money.

TfL also recently launched its near field communication (NFC) contactless payment systems for buses.
