Gareth Llewelyn MCIHT Technical Operations Manager, HCP (UK Highways M40) stated:
“On an annual basis Crown Plus develop a programme of detailed inspections that meet the requirements of TRMM. They undertake the role of Principal Contractor and
are responsible for organising all traffic management and road space bookings.
“Crown have also brought added value to the works by identifying and recording all drainage asset locations with GPS equipment and providing as built drawings. All cross-carriageway drainage has been inspected for condition and connectivity using the Quick View method.
“We have been very pleased with the works undertaken by Crown and we view them as an integral part of our supply chain. They demonstrate the core values of integrity, collaboration and professionalism and always strive to deliver works in the most efficient way possible.”
