Survey and Surfaces

The main Devotech iDAS tools for survey and surfaces are the following:

  • Autodesk® Civil 3D® template based on the TMH11 standard
  • Rename COGO points in the selection sequence
  • Add station, offset and alignment name from alignment to COGO point properties
  • Import and export GPX (Garmin GPS)
  • Link points to create survey features
  • South African coordinate system translation
  • Import surface from Model Maker TOT file and export surface to TOT file
  • Import surface from Civil Designer DAT file

Platforms

The main Devotech iDAS tools for platform design are the following:

  • Calculate platform layerworks quantities automatically
  • Create setting out points for cut and fill automatically
  • Create volume surface table

Urban Roads

Urban roads design requires a lot of repetitive tasks which can be minimized by using Devotech iDAS. Very often the road centrelines are available as polylines. Devotech iDAS has a command which converts polylines to Autodesk® Civil 3D® corridors. All the objects are created automatically including horizontal alignments, profile views, vertical alignments, corridors, top surfaces, datum surfaces and sample lines. The designer just needs to focus on the actual design by adjusting the objects. Devotech iDAS also provides tools to create intersections automatically, to change labels for multiple alignments at once, modify multiple profile views and section views in terms of height and datum, as well as tools for quick navigation within the drawing.
It is often required to design a channel on the low side of the road and a barrier curb on the high side of the road. Devotech iDAS contains a conditional subassembly which automatically determines whether the road edge is on the low side or high side and applies appropriate subassemblies.
Devotech iDAS also provides tools for plan production so that the plan and profile sheets can be created for all the roads at once.

Single Carriageways

Single carriageway design can sometimes be challenging and the most important part is to keep all the objects dynamic. Devotech iDAS provides tools to link drainage and

guardrail details in the profile views (longsections) dynamically with the corridor. The other major benefit is that Devotech iDAS can link profiles dynamically with the corridor so that the profiles of the road edges are dynamic and they do not need to be recreated every time the design changes. Devotech iDAS also contains a subassembly for cut/fill based on SANRAL (South African Road Agency) requirements.

iDas Dual Carriageway

Dual Carriageway

Dual carriageways can have very complex geometry with different horizontal and vertical alignments for each carriageway. This introduces various width and height differences at the median. Devotech iDAS has a tool to link profiles dynamically to corridors which allows it to link the median geometry to carriageways so that the entire corridor updates automatically. Other tools allow the user to link drainage and guardrail details in the profile views (longsections) dynamically to the corridor. Devotech iDAS also provides various subassemblies which can be used for the dual carriageways:
  • Lane subassembly which has inside and outside width and shift width
  • Median subassembly with retaining wall which automatically creates channel, barrier or barrier with retaining wall according to the vertical difference between carriageway’s inside edges
  • Cut/fill subassembly based on SANRAL (South African Road Agency) requirements

Stormwater Networks

The main Devotech iDAS tools for stormwater networks design and analysis are the following:

  • Extensive pipe catalogue
  • Custom pipe and structure properties, e.g. design flow and velocity, maximum flow and velocity, curb inlet type, inflow, lateral inflow etc.
  • Convert multiple lines and polylines to pipe network
  • Swap multiple pipes or structures simultaneously
  • Create profile views (longsections) for entire network automatically
  • Regrade entire network automatically
  • Grade multiple pipes at once (forward or backwards)
  • Run-off calculation based on Rational and Epaswmm methods
  • Pipe and structure quantities

Water Reticulation Networks

The main Devotech iDAS tools for water reticulation design and analysis are the following:
  • Custom pipe and structure properties like design flow, velocity, inflow,
  • lateral inflow, pressure etc.
  • Convert multiple lines and polylines to pipe network
  • Add house connections
  • Swap multiple pipes or structures simultaneously
  • Adjust the invert or cover for entire network
  • Water reticulation analysis
  • Valves
  • Pressure map
  • Pipe and structure quantities
  • Excavation quantities according to SABS 1200
  • Rename pipes and structures
