STRINGS-BASED EARTHWORKS DESIGN
The digital terrain modelling program provides interactive and dynamic strings-based earthworks design and calculations. It incorporates extensive survey reduction routines, survey calculations, error figures, control surveys as well as giving you powerful bulk earthworks modelling.

Civil Designer's strings based earthworks design functionality now supports child strings on both sides of the master string, for more flexibility in the design of complex platforms.




 
 


POWERFUL DTM

Civil Designer's DTM engine is the strongest in the industry. You wonít experience issues with modelling & breaklines changing for no reason from the original validated DTM after importing. The module has been optimized to import 4 million points in under a minute and can further handle 95 million points with ease.





DAM WALL AND WATER EXTENTS  

DAM WALL AND WATER EXTENTS

This video demonstrates the design of a dam wall with terrain strings to generate a merged model with contours, dam water volume (taking into account any islands), earthworks volume, the dam floodline and exporting to Google Earth to visualise the water extent.





Adding Erf dimensions  

Adding Erf dimensions

This video demonstrates how to add Erf dimensions and dimension multiple erven by specifying the relevant range.





Earthworks volumes  

Earthworks volumes

Model up to 255 terrain surfaces and calculate the volume difference between any two surfaces, in the video example - the annual surfaces of a quarry. View cross sections of one or more surfaces and keep track of earthwork volumes between recorded periods, calculate excavation volumes between two surfaces and cut and fill quatities.





Strings based earthworks design

Civil Designer's strings based earthworks design functionality now supports child strings on both side of the master string, for more flexibility in the design of complex platforms.





Draft Expert  

Draft Expert

Generate CAD entities for topographic drawings according to defined point name rules, which can then be re-used as required.

Point to point linkage can be automated and is made faster and easier. Layer names, colours and styles can also be stored as template settings for future drawings.

See this article on Surveying with the Draft Expert (as published in Position IT) for more details on this functionality.





Observations & Figures Database

Easy interface for managing total station records and you can perform survey calculations from total station records. Measurementa can be imported and stored with your drawings for use with all associated survey calculations.





SG Diagrams

Generate SG diagrams from survey points and figures with customisable drawing scale.





Survey Point Screening

Civil Designer's Manual and Automatic Screening functionality allow the intelligent reduction of the number of points in a large data sets by specifiable height tolerances and point proximities.





Raw Survey Point Name Classification

This feature is particularly useful when working with DTM data from LiDAR surveys. Civil Designer will sequentially name points with optional feature line between renamed points to allow easy classification of raw survey data. Survey points can also automatically be named within a specified distance from CAD lines, arcs or polylines, in order to identify features such as road centre lines, road edges, shoulder break point lines, toe lines etc.





Faster triangulation algorithm also handles larger data sets

Intelli-Line break line generation allows you to use cheap computer time to define the model features by survey point names, instead of slow and painful manual breakline definition. Thereafter fill in the rest of the site in a matter of seconds. Alternatively use the lightning fast triangulation (3 million points in 100 seconds) for more uniform sites.





FASTER TECHNIQUES FOR SURVEY REDUCTIONS

You don't have to classify surveyed information in groups, descriptions and setup settings which can be confusing and time consuming.





MULTIPLE TERRACES in Civil Designer  

MULTIPLE TERRACES WITH CUT/FILL OPTIMIZATION AND DYNAMIC UPDATE

You can create a terrace in a number of ways - by importing, typing or graphically defining the corner co-ordinates. Generate the terrace banks and toe points with fixed or variable slopes by simply specifying the bank criteria. If you donít like the terrace you can change the layout or simply drag it to another position on the site. You can even manipulate an individual terrace on a multi-terrace site.





CUT/FILL TERRACE in Civil Designer  

CUT/FILL TERRACE OPTIMIZATION TO MINIMIZE COSTS

The volume of a terrace can be calculated in seconds. Cut and fill volumes can be balanced with the optimization function to the percentage that you require. You can even manipulate an individual terrace on a multi-terrace site. Design more cost effectively by calculating the volumes and optimizing costs before projects are built.





SABS1200 OR COLTO VOLUMES IN DEPTH INCREMENTS

Once you have finalised your design you can merge the terrace(s) with the underlying ground profile to create a final site model quickly and easily. You can choose to have the volumes reported in either SABS 1200 or COLTO format with user-defined depth categories, topsoil stripping and compaction or bulking factors.





CATCHMENT AREA in Civil Designer  

CATCHMENT AREA AND DRAINAGE FLOW PATH ANALYSIS

The Flow Directions function uses the 8-point pour algorithm to determine the route that water would flow from a given position. The Drainage Network function uses the flow accumulation algorithm to determine the dominant water routes over an entire surface. Defining the end of a water course allows the program to determine the corresponding catchment area.





RENDERED 3D VIEWS in Civil Designer  

RENDERED 3D VIEWS, IMAGE OVERLAYS, CONTOURS & FLY-THROUGH

To help you to see the bigger picture you can visualize the final project in a rendered three-dimensional view, with light source, textures and image draping. You can also do a virtual fly-through of the site if you want to.





CONVERT POLYLINES TO DTM in Civil Designer  

Convert multiple 3D polylines to DTM

Civil Designer will create DTM points using the z-coordinates of 3D polylines. If you have a 3D drawing, it is no longer necessary to process each polyline one by one. You can simply select multiple entities, or process an entire CAD layer.





Fast Accurate DTM Line Model Creation

Civil Designer will now create an accurate DTM model with break or feature lines from a CAD drawing and an associated survey. The new model is generated from only the survey points at the beginning and end of each CAD line and is stored in its own new destination surface.





Convert 2D CAD lines to 3D CAD Lines

Civil Designer will now convert 2D CAD lines to 3D CAD Lines by draping the original CAD lines on associated DTM surface to determine the new third dimension's elevations.





CROSSING SERVICES  in Civil Designer  

CROSSING SERVICES DISPLAYED ON PLAN, LONG AND CROSS SECTIONS

Pipe and services databases (sewer pipes, storm water culverts, water networks, electrical layouts and telecommunication cables, etc) can be imported or added into Civil Designer to indicate crossing positions of the pipes/cables on road, sewer, storm and water services. The crossing services will be displayed and plotted on all layout plans, long and cross sections.





extract long sections in Civil Designer  

EXTRACT LONG AND CROSS SECTIONS ALONG ANY ALIGNMENT

This function is used to extract long sections from ground or design data along a pre-defined route. Cross and long sections may be extracted from either lines or points.





pipe functions in Civil Designer  

PIPE LONG SECTIONS

The pipe functions allow you to generate pipeline long and cross sections, with pipes between manholes, pipes defined by length or pipes parallel to the ground profile.





TRENCH VOLUME CALCULATOR

Calculate the earthworks volume for the pipeline trench separated up into various material types and pay depths. Trench lengths for each depth increment will also be determined. You additionally have the option of setting pay depth increments. After the information is entered, the routine produces a listing of volumes for each depth increment from one manhole to another.





SURVEY CALCULATIONS, ERROR FIGURES AND CONTROL SURVEYS

The functions in the Survey Module permit you to gather, compute and edit data from a variety of sources. The Terrain Module functions create a 3D mathematical model of one or more surfaces and permit information such as contours, volumes and sections to be derived from it. Data can be manipulated from the basic collection stages all the way through to final contract drawings.

The Error figures features adjust a provisionally fixed point that has redundant observations by means of a least squares solution, or a graphical fix of the error figure, or both. A rough fix for the point should be calculated prior to using this routine and usually this will be done under Survey Calculations. The data for the calculation must be provided in the form of a field book.

Control Surveys allow you to perform a least-squares adjustment of a network of 2D points and associated distance and direction observations. You are also given the resultant error statistics.





POWERFUL SURVEY REDUCTION ROUTINES

TACHE REDUCTION: Tache data can be typed directly into the spreadsheet. Each line of the spreadsheet represents a set-up station, an outward orienting ray or a tache observation. Tache observations can either be an EDM or prism observation, a tache or staff observation or a polar observation (generally from a total station).

FLAT TRAVERSE: This function reduces a conventional simple traverse, in which it is assumed that all distance reductions have been carried out separately and that the distances supplied have been reduced to the horizontal. It therefore does not require the entry of the vertical angles unless a height traverse has been incorporated. It can also be used for theoretical calculations, such as cadastral reconstruction, where an adjustment is required.

FULL TRAVERSE: This routine is used to reduce a traverse where the distances provided must be reduced to the horizontal and also require correction for Sea Level, Scale and Temperature. Vertical angles must therefore be supplied in the field book and the average elevation of the traverse and the temperature correction will have to be supplied.

SLOPE TRAVERSE: A slope traverse, using slope distances, can be reduced by incorporating vertical angles.

SPIRIT LEVEL REDUCTIONS: These routines permit the reduction of normal and cross-section spirit levels by the rise and fall method. The data for spirit level reductions must be provided in the form of an ASCII field book file.





DRAWING TEMPLATES (SHEET FILES)

Using our drawing templates (sheet files), you can generate production drawings with detailed title blocks, north signs, grids, company logos, annotations, data lists, scale bars and much more so that your plotting requires little, if any, CAD editing. No longer do you have to cut and paste your design into your title block as our flexible sheet files allow the precise placement of all the design elements in your title block with customizable settings. Our powerful sheet files allow you to define exactly what the final production drawings should look like saving you hours of postproduction CAD editing.





HELMERT AND GEO-TOPO TRANSFORMATIONS

If more than two points have known coordinates on both systems there is redundancy and a least square (Helmert) system can be used to obtain the final parameters.

Geo-Topo transformation can be used to convert geographical co-ordinates in the form of degrees, minutes and seconds of latitude and longitude, to Y and X coordinates in the project projection in Civil Designer format. An ASCII file is read and another one is written. The converted coordinates can be set relative to any standard line of longitude.





SUPPORTS ASCII, BOOKER, LOGGER, WILD, GEODOS, CEASER AND SOKKIA

We support many different data formats (field books) that can be imported into Civil Designer. Terrain point co-ordinates may also be exported to total stations or to WILD equipment. All ASCII file imports have been made super fast and multiple ASCII files can be imported into the DTM in one operation.
