Costs tab

In this tab, the costs for the trench construction—Civil works costs—and for general equipment—Equipment costs—are defined.

In principle, a differentiation is made between the price of materials and the price of labor.

Civil Works Costs


The communicated costs are taken into account per meter—variable costs—or according to fixed costs per record.

Explanation of the trench construction types

Standard Trench Longitudinal trenches 
Standard Crossing Street crossings
Drop Trench Drop trenches
Use of existing Pipes Shared use of existing empty ducts
Use of existing Cables  Use of existing cables 
Use of Aerial connection between Poles Aerial longitudinal trenches
Use of Aerial connection to Poles Aerial drop segments
Use of Façade connections Longitudinal segments on Façades
Use of Façade Drop connection Drop segments on Façades
Use of Façade Span connection Bracing segments on Façades


The costs defined here will be used for all segments/trenches, regardless of the segment/trench type. Under SubType, the various segment/trench types (construction methods) can be priced in a dedicated manner.


Clicking on the “Import SUBTYPEs” button imports all segment/trench types created in the project and to provide them with a price. The segment/trench types are imported or assigned when importing or manually creating street center lines. Each segment/trench type can be priced as a longitudinal run or street crossing. The x at the end of each line can be used to delete the entry.


You can start the manual creation of subtype by clicking the “Add another SUBTYPE” button. Pay attention to the correct spelling. 

In addition to the trench types described above, trench connections between different parts of the networks, such as between civil works and shared use of existing duct, can be priced in a dedicated manner.


Equipment Costs

Here, different costs can be defined for new equipment to be built—new costs—or for upgrading existing equipment—existing costs. The attribute “Existing” at specified structures or layer points defines which costs are used for the calculation.

Explanation of the equipment 


Joint Closure in the manhole for multi-use cable


Splice/connectors in FO points

Micro Duct Connector Fittings for microducts
Duct Branch Location Fittings or T-pieces of composite ducts
Duct Taper Location Duct taper of the composite ducts
Manhole The manhole in which the closure (Item 1) is located 
Handhole Handhole
Pole/Antenna Pole/antenna
Drop box / Aerial drop box Component that is applied to the branch—microduct in the composite for drop microducts
Cabinet Structural facility in which the FO distribution point is located
Central Office CO or POP at drop layer
OLT/ODF Equipment in the Central Office
Backbone devices Backbone point



comsof fiber designer calculates the fittings of composites for tapering and branching and the fittings of the microducts to be connected there. The fittings of the drop microducts to the microducts in the composite are not included in the bill of material. The NET export corrects this. The number of fittings is correct in the detailed planning project.
