KMG aims to minimise the impact on the countryside. Every square metre of untouched landscape which can be permanently preserved as part of the Danish countryside is of value. By preserving the landscape, less use will be made of excavation machinery, thus reducing harmful emissions. KMG views the handling of natural resources in a similar way. KMG's partners have successfully promoted innovative solutions for several decades. Among other things, this philosophy will allow existing soil to be fully utilised in the coming construction project.
KMG aims to ensure optimum solutions for all project participants. KMG views the bulk management of soil as a means of optimising the project by minimising the amount of, and utilising, surplus soil.
KMG's longitudinal solution for the motorway is not dissimilar to that issued by the Danish Road Directorate in connection with the tendering phase. KMG has, however, tried to optimise the longitudinal profile even more so as to create the best solution.
With the longitudinal profile presented by KMG, a total of some 2,900,000 m³ soil will have to be redistributed within the confines of the project. It is an indispensable requirement that all phases shall be completed perfectly and all personnel shall do their absolute best to achieve the optimum result. Through the use of 200 GPS-controlled construction machines for earthworks and a production rate of 30,000 cubic meters per day, the earthwork will be completed in record time. The vision of achieving perfection requires experience, technological know-how and a willingness to embrace and understand new technologies.
Early on, KMG recognised the value of soil as a raw material, and wishes to incorporate this principle in the project. For more than 35 years, STRABAG has been a technology and quality conscious market leader in the field of soil stabilisation and compaction, treating more than a million square metres annually. A wealth of opportunity exists for improving the resistance and incorporation properties of soil using various binding agents. Generally, requirements on cost and environmental impact are decisive.
For KMG, optimum carriageway drainage is a basic element in any successful motorway concession. If drainage is sub-optimal, the service life of the road will be reduced and the risk of accidents increased. During planning, design calculation and material selection, our focus has therefore been on ensuring safe use of the motorway throughout its entire life cycle.
Through the use of the slot rinne this approach will be implemented into reality.
Already in autumn 2010 the external drainage is completed.
For KMG, asphalt incorporation and quality are decisive for the success of any motorway concession. As Europe's largest road-building company and leading partner in KMG, STRABAG will demonstrate its full range of skills in asphalt technology in connection with the PPP Kliplev-Sønderborg project. KMG has thus assessed the best asphalt compositions during the tendering phase and initial tests have already been performed. Besides producing the asphalt types in our own mixing plant, and using special incorporation technologies, KMG will ensure that surfacing is performed in the best possible quality.
The STRABAG Group will ensure that the surfacing meets the requirements of both the Danish Road Directorate and KMG in each individual step, from raw material purchase, through transport and production to incorporation and quality control. Only in this way can an end product of highest quality be obtained.
Bridges and Passages
The project was prepared on the basis of the many years' experience of bridge building amassed by the KMG partners. Generally speaking, all the requirements of the tender documents have been met.
The project contains a total of 72 bridges and passages, i.e. 11 overpasses, 30 underpasses, 26 fauna/amphibian passages and 5 conduits for slurry pipes.
Because of the bridges' importance in a future road network with expected high traffic intensity, the project has been prepared with the overall objective of ensuring transport facilities of high quality and technical supremacy. The clear purpose of this objective is to ensure minimal future maintenance of the bridges and passages.
The bridges and passages have therefore been consciously designed as sound, robust structures with a minimum of joints and fixtures (bearings, manholes, drainage pipes, etc.), as it is often such elements which subsequently require most maintenance. The majority of the solutions offered are therefore based on a frame bridge concept, providing an advantageous static design with no need for bearings, etc.
