We believe that developing long-term relationships with all who provide services to our business is crucial to our ability to provide our clients and customers with projects that deliver to the highest standard. Our business has been built on a collaborative culture. Through early engagement and working in partnership with these suppliers, we can address key performance requirements for health, safety, environmental and other CR matters.

Our Building and Infrastructure businesses have a number of key clients, particularly those that operate through five year framework agreements. Although no one client has accounted for more than 4% of revenue during the year major clients, both during the year and currently, include:
 

• The seven regulated water utilities for whom we are working under five year framework contracts for their asset management programmes.
• Lend Lease, for whom we are carrying out accommodation building works for the Olympic Games in 2012.
• Manhattan Loft Limited, for whom we completed a £103 million contract to redevelop St Pancras Chambers in London.
• Transport Scotland for whom we carry out highways projects and who is the client for the recently awarded Forth Road Crossing project.

Business partners

We carry out some of our projects in joint ventures. Our partners are engineers, other contractors and consultants on our frameworks for the water utilities and our larger highways projects. During the year we secured the £790 million Forth Road Crossing project in a consortium with Dragados, Hochtief and American Bridge.
In housebuilding we develop a number of sites under joint venture agreements with housing associations and other housebuilders.
Significant relationships in our housebuilding business include our partnership with the Homes and Communities Agency.
We have major projects with Affinity Sutton and the Devon and Cornwall Housing Associations together with developers Wates and Crest Nicholson with whom we have joint ventures. Going forward the Home Group is our joint venture partner on the £347 million
Gateshead evolution regeneration project for Gateshead Council on which we were appointed preferred bidder during the year.
