Engineering and property services - including estates management - will be run by Jacobs until 2012 with potential for extension to 2016.
The engineering consultancy contract was initially outsourced in 1999 and has been delivered by Mouchel Parkman. The property service is currently provided by the in-house building, design and management unit. TUPE will apply to both staff transfers, involving over 170 staff.
Jacobs will work in partnership with Raynesway Construction Southern Ltd, the highways term maintenance contractor in the delivery of the service provided by Highways North Yorkshire.
Current expenditure by North Yorkshire CC on fees and professional services is: engineering£3m (approx) per annum, property£4m (approx) per annum.
North Yorkshire CC executive member for business and environmental services, Peter Sowray, said:
'The services they will be providing are extremely important in ensuring the smooth running of the council and of the delivery of vitally important public services.'
Jacobs has partnership contracts with local authorities including Buckinghamshire, Coventry, Kent, Lincolnshire, Oxfordshire, and Wolverhampton.
