Technical service provider Croonwolter&dros, consulting and engineering organization Arcadis and construction company Hollandia Services will maintain and renovate several bridges and locks for Rijkswaterstaat in the south of the Netherlands (West Netherlands-South, North and South districts). Of the eight bridges and four locks, the most famous objects are the Van Brienenoord bridge, the Spijkenisse bridge and the Merwede bridge. This contract involves a contract value of 7.5 million euros.
The main task for this large-scale assignment is the optimal functioning of the bridges and locks. With the increasing use of (sailing) roads, they must be able to flow safely. This means that efficient maintenance is necessary to keep the objects in good condition for the long term. The companies work together in the combination ‘Sherpa Asset Management’.
In order to work efficient, all data is in one system. This concerns the maintenance data, analyzes, requirements sets and processes. It ensures all the information complete, correct and current. The relationship between maintenance and the performance of the network is therefore concrete, reliable and predictable.
“The management and maintenance of objects is becoming increasingly important in the coming years,” says Harm Albert Zanting, division director of Water Arcadis. “Many of these building are around fifty years old and were made for a much lower capacity. With our collaboration, we show important long-term bridges and locks to meet current requirements.
“Locks and bridges contain a lot of software hidden. The object must be able to be move and operated. In order to achieve this, the knowledge of experts is required. Because of the numerous extensive projects these companies completed together, we have practical insights, years of experience and in-house developed hardware and software, which benefit the objects for this project, says Jan Willemsen Division Director Infra at Croonwolter&dros”.
As renowned company, Hollandia has been involved in bridges and locks for the steel and mechanical parts of these objects for many decades. “We regularly use our own archive,” says Ronald van den Berg, director of Hollandia Services. “Through this (historical) knowledge and expertise we have been successful in the maintenance of these works of art for many years. Due to addition of the knowledge of Arcadis and Croonwolter&dros, we have offered a more than full service package.”
