Cost

the cost objective captures the estimated cost (in unit of currency) of a route costs are usually made up of capital expenditure (capex) and operational expenditure (opex) the costs associated at a location along a route are effected by the asset at that location (cable, tower, tower foundation etc ) the gis layers at that location the elevation and / or slope at that locations when you are configuring the costs associated with gis layer, note that these are summed at any point therefore the costs you apply to gis layers are additional costs to material costs wood poles and steel lattice towers you can configure unit costs for the following cost of constructing a standard transmission line structure cost of constructing an angled transmission line structure cost per metre of conductor where a transmission line structure may be a pole (wood or steel) or a steel lattice tower the total capex contribution from this will be {capex} {unit} = (n {assets} {cost} {asset}) + (n {angled} {cost} {angled}) + ({length} {cost} {conductor}) where ${length}$ is the total length of segments that are between the structures and $x {angled}$ indicates that the value relates to an angled structure trenched and trenchless underground installation you can configure unit costs for the following cable cost per unit distance base cost per cable section the total capex contribution from this will be {capex} {unit} = ({length} {cable} {cost} {unit}) + (n {sections} {cost} {base}) where $n {sections}$ is the number of discrete continuous cable sections costs of crossing gis polygon layers you can configure the following cost properties for each gis layer the route crosses this can represent costs incurred from forestry works along a route there are two core components to the cost calculation for crossing gis layers linear cost base cost the linear cost is multiplied for the distance the gis layer is traversed (on top of the conductor cost, and base cost is applied once per every instance that the gis layer is traversed the total capex contribution for a single layer therefore is {capex} {layer} = ({distance} {layer} {cost} {linear}) + (n {segments} {cost} {base}) where ${distance} {layer}$ is the total distance travelled through a particular layer for this asset $n {segments}$ is the number of contiguous segments of the route that go through this layer costs of crossing existing linear infrastructure you can configure the following cost properties for each type of existing infrastructure the route crosses linear cost base cost width of crossing the total capex contribution for a single crossing type (e g major roads) will then be {capex} {crossings} = (n {crossings} {width} {cost} {linear}) + (n {crossings} {cost} {base}) this is summed for all crossing types to arrive at a total cost of crossing linear features opex tba reworks being discussed
