4 core drilling holes shall be used, with lengths of 1 500-2 000 metres. Considerations shall be taken in relation to local conditions at the drilling sites, such as soil conditions, access as well as preservation and landowner interests. Accessibility to necessary equipment and workplace must be partly developed on each location. Beside the actual foundation for machines, the terrain shall be spared for intervention. It is therefore recommended that a work platform is developed for the central working area. Separate supplies of water and power must be arranged, as well as the necessary facilities for the work crew.D 1.2 DrillingIn connection with core drilling the requirements regarding extent and execution stated in the Norwegian Public Roads Administration's (Statens vegvesen) Manual R 211 – Chapter 15.255, shall be complied with.It is a condition that the drilling dimension NQ (outer diameter approx. 76 mm and core diameter approx. 48 mm) is used in connection with choice of machine and price. Alternative drilling diameter can be offered, as long as improved implementation safety is substantiated. In the deviated core path, the core diameter is adapted the special equipment as a consequence of the method used by the special supplierThe 4 drilling holes included in the tender documents are:1. From Otterøya:The drilling location contains uncovered rock and is located at the end of a tractor road, approx. 5 m above sea level. The planned hole path is 1 525 m and described in the 3 following sections:1): start angle: 45°, straight hole path with a length of 300 m,2): deflection in the vertical plane, radius 400 m, length 325 m,3): straight hole path with approx. 3° drop, length 900 m.2. FromTautra facing north:The drilling location contains approx. 0, 5 - 1,0 m moor with heather ling vegetation over uncovered rock and is located up to 200 m from the designated landing location, approx. 10 m above sea level. The planned hole path of 1650 m is described in the 3 following sections:1): start angle: 45°, straight hole path with a length of 325 m,2): deflection in the vertical plane, radius 400 m, length 325 m,3): straight hole path with approx. 3° drop, length 1 000 m.3. From Tautra facing south:The drilling location is assumed to be identical with no. 2. The planned hole path with a length of 1 400 m is described in the 3 following sections:1): start angle: 45°, straight hole path with a length of 220 m,2): deflection in the vertical plane, radius 400 m, length 350 m,3): straight hole path approx. horizontal, length 800 m.4. From Vik facing north-west:The drilling locations contains approx. 10 m glacial deposit above rock and is located up to 50 m from the local gravel road, approx. 15 m above sea level. The planned hole path has a length of 2 175 m and is described in the 4 following sections:1): Drilling through casing in uncompacted material, angle 45°, length 15 m2): Drilling in rock with an angle of 45°, straight hole path in a length of 50 m,3): deflection in the vertical plane, radius 400 m, length 325 m,4): straight hole path with an approx. 3° drop, length 1 800 m.See also the tender documentation for further description of the project.20 000 00040 000 000
