Inventor David Baker accepted the award from CIHT Patron, Her Royal Highness, The Princess Royal, at a gala dinner in London. The judges enthused over this innovative yet simple idea. Following value engineering, this design modification resulted in large cost savings and greatly increased productivity for this fast-track project. In addition, the reduction in materials used of 30 to 40% has resulted in economic, sustainable and environmental benefits. This novel construction technique significantly reduced the construction time and minimised disruption on a long section of the M25. Judges were also impressed by the communication and consultation between all parties involved which resulted in the use of an untried system on such a major project.
