Road and terrain

The whole road project, from the survey point to the mass haul diagram, runs in the same file. Superelevation and spirals follow KGM (General Directorate of Highways).

Terrain

The terrain surface is built from the data you have. Satellite imagery and institutional background maps are placed behind the drawing.

  • Points and TINSurface from survey points
  • Point cloudLAS and LAZ files
  • Background mapsSatellite imagery and institutional background maps

Points and surface

Survey points are managed in a single table. The surface is built from whatever data you have.

  • Point editorFiltering, bulk elevation assignment, renumbering
  • Point groupsGroups by rule, display settings per group
  • Surface sourcesPoints, elevation labels, triangles, DEM and LandXML
  • Surface toolsExtracting contours and boundary lines, offsetting the surface
Point editor window: point table and bulk-edit row

Ground investigation

Borehole data is brought into the drawing. Strata and groundwater appear at the boreholes' positions on the longitudinal profile.

  • DataFrom Excel, CSV and AGS4 files
  • Columns on the profileStratum, SPT and groundwater in each borehole column
  • Stratum surfaceA stratum surface is built between boreholes
Eight borehole columns on a longitudinal profile: stratum hatches, stratum boundaries between boreholes and the groundwater line

Borehole log

Each borehole's log is drawn as a sheet: strata, tests and groundwater by depth on the same page.

  • StrataWith a depth ruler and soil-class hatching
  • TestsSPT, sample and core values
  • GroundwaterMeasured levels

Alignment

Horizontal geometry is built with curves and spirals (clothoids). Superelevation and plan display follow KGM practice.

  • Curve and spiral (clothoid)The transition curve is a clothoid
  • SuperelevationCalculated per KGM
  • Plan displayCurve data block and superelevation band
Alignment in plan: curve, sample lines, slope limit and curve data block

Profile and design profile

The design profile is drawn on the longitudinal profile. Vertical curve values come from the KGM handbook tables.

  • Longitudinal profileOn the terrain profile
  • Design profileTogether with the vertical curve
  • Superelevation bandBelow the profile, by chainage

Typical section

The road cross-section is defined piece by piece: lane, shoulder, cycle path, pavement, slope, wall. Ready-made sections come from the KGM library.

  • LibraryKGM typical section library
  • PreviewThe section is redrawn as you change it
  • Section from drawingA definition is extracted from an existing section drawing

Corridor

When the alignment, design profile and typical section come together, the 3D road model, the corridor, is created.

  • 3D modelLanes, pavement, slope and wall sit on the terrain
  • IntersectionAt-grade intersection and roundabout
  • Corridor surfaceSurfaces and lines are extracted from the corridor

Earthwork volumes

Cut and fill volumes are calculated from the road model.

  • Cut and fillBy soil class
  • Mass haul diagramHaul-balanced
  • Periodic volumesDelivered as an Excel file
  • Volume dashboardAll volume results in one table
  • Volume between two surfacesCut and fill between two surfaces

Excavation design and site grading

A foundation pit, a platform or site grading is defined by a formation level and slopes; the volume is calculated right away.

  • Excavation designFormation level, slope gradient and benches
  • Site gradingCut and fill for a site
  • 3D resultFormation and slopes are shown on the terrain

Plainly: what it does not do

  • It does not write DWG (drawings are delivered as DXF).
  • It does not produce a PDF of the sheets.
  • It does not calculate retaining walls; the wall shown in a section is representative.
  • Road rehabilitation is out of scope.

Frequently asked questions

Can I open my existing DWG projects?
DWG and DXF files are read. DWG is not written; drawings are delivered as DXF. Alignment and surface are exchanged through LandXML.
Which institutional rules are included?
The rules of İller Bankası (Turkey's municipal development bank), İSKİ (Istanbul Water and Sewerage Administration) and DSİ (State Hydraulic Works), and the tables of the KGM (General Directorate of Highways) handbook are built into the program. Every value carries its source; a value whose source is not verified does not enter the calculation.
