Levels of engineering support
NM Group has the experience, the expertise, and the skills to support Transmission Line Engineers, in a number of different ways.
Level 1 LiDAR data, classified with feature codes as defined by the client, is imported into a .bak file. This is then ready for a Transmission Line Engineer to begin modelling the towers, stringing and sagging the conductor.
Level 2A We take the .bak file produced above, and create the Method 1 (Stick) structures. We then string the relevant conductors to suit the as- installed arrangements and conditions. This is now ready for a Transmission Line Engineer to run clearance reports, analyse thermal and structural capacities, etc.
Level 2B We take the .bak file produced above and import the Method 4 (Structural Model) structures. We then string the relevant conductors to suit the as-installed arrangements and conditions. This is now ready for a Transmission Line Engineer to run clearance reports, analyse thermal and structural capacities, etc.
Level 3 Using the model complete with Towers and Conductors as above, we perform analysis on clearances for regulatory compliance and vegetation management, and structural loading. This is now suitable for a Transmission Line Engineer to consider options to enhance the thermal, clearance, or structural performance of the circuit.
Level 4 Our experienced powerline engineers produce an ‘optioneering’ study. This will assess the relative merits of the viable, available options to resolve clearances and/or structural issues.
