ground the work is usually performed using excavation equipment and large lorries. Excavation takes time and obstructs other traffic in the area sometimes it is necessary to close roads to other traffic while the excavation work takes place. methods are coming in at full speed When we and our sub-contractors are planning our work to connect households and companies to our networks we now increasingly use considerate and environmentally friendly methods. With micro- trenching and sub-channeling cables can be laid out to customers more quickly and with less disturbance to nature. ConstruCtion methods save the environment narrow trench in the asphalt. We lay micro pipes in this cut trench and we can then install micro (fibre) cables in the micro pipes. Sub-channeling means that we install "micro sub-pipes" in existing pipes. This gives us room for more cables in pipes which would traditionally be regarded as full and we therefore avoid new excavations. calculate the environmental benefit Telenor has developed an environmental calculator to calculate the degree to which sub-channeling and micro-trenching can reduce CO the need for such a calculator because the new methods were unknown in many municipalities, which were therefore sceptical about giving permission for the new methods rather than traditional construction methods. At Telenor Norway we regard these as environmentally friendly, effective and safe methods, and the increased use of micro-trenching and sub- channeling will have great social value. methods honoured with environmental award In addition to conducting pioneering activities which have a substantial effect on our overall environmental balance Telenor Norway's micro trenching and sub- channeling experts have been exemplary in their work to explain and visualise the effects of the new construction methods. These experts were therefore pronounced Telenor Norway's internal environmental heroes in the third quarter of 2012. |
