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
| Closure |
Joint Closure in the manhole for multi-use cable |
| Splice/Connector |
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 |
Note
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.
