FUNDAMENT FOR KRAFTLINJER
Fundamenter for 132kV høyspentlinje Kvandal - Kanstadbotn
Construction of foundations for the new 132kV transmission line Kvandal-Kanstadbotn, between Narvik and Harstad Municipality.
Duci Norge project main scope is construction of around 200 new foundations and some access road services to replace existing 132 kV transmission line with a new one from Kvandal to Kanstadbotn substation and two transmission line to Hålogaland Kraft's new substation in Boltåsen. Work place is between the Narvik and Harstad Municipality. The approximately length of the TL is 74 km. Type of foundations are concrete, around 85% rock foundations and around 15% soil foundations.
PHASE 1
Main challenges
One of the main challenges is the construction of foundations underneath existing (energized or deenergized) transmission line. The existing transmission line act as an obstruction making the transport of people, equipment and materials more demanding than usual.
PHASE 2
Area
The terrain is rough in parts along the line route, and altitude varies. During autumn/winter the natural light is limited as this part of Norway is north of the Arctic Circle and polar nights prevails. The area is characterized with rapid changes in weather conditions, which may be harsh due to wind, rain, fog, snow and ice, and limitations to working operations may appear whole year around. There are some areas exposed to avalanches (snow and rock).
FINAL PART
The powerline passes through two nature reserves and ecologically sensitive areas (bogs, riversides, etc.) might demand special measures in the construction period, Sommervatn and Myrvatnet wetlands. Work must be planned based on no admittance between 15th of May – 15th of August every year.
The powerline runs through three reindeer farming areas, and in ecological sensitive areas. In summer and winter many areas are used for outdoor activities such as hiking, skiing, fishing, hunting.
Special consideration when working in areas with reindeer. In vulnerable areas there are restrictions on use of helicopter below 1000 ft.
