Using 12d Models screen menus and fast interactive graphics, the user effortlessly moves through a design.

With 12d Models powerful design capabilities, difficult surveying and civil design tasks can be easily visualized and completed.

Projects such as roads, channels, storage tanks, subdivisions, landscaping, rail studies, major pipelines, waste water reticulation and general site works are efficiently handled with 12d Model.

12d Model includes a powerful programming language which allows users to build their own options from 12d Models extensive programming library.

12d Model features data exchange with drainage and river analysis packages including XP-SWMM, XP-UDD, Drains, ILSAX, PC Drain, RATHGL and HEC-RAS, survey packages such as TP Setout as well as the CAD systems IntelliCAD, AutoCAD and Microstation.

12d Model is a totally Australian product, running on Windows NT, 95, 98, 2000 and XP (including PC Notebooks).

12d Model has been specifically designed for easy use. It is ideal for use at all stages of projects, and is particularly useful for large route selection and corridor studies.12d Model is an essential tool in today's fiercely competitive business climate.

Rivers

There are six modules for rivers work: HEC RAS Advanced, XP SWMM, Mike 11, UNET and ISIS.

These modules create the natural cross section files for HEC RAS, XP-SWMM, XP-UDD, Mike11, UNET and ISIS respectively. The water level results from these packages can then be read back into 12d to create a detailed water surface that accurately defines the river bank between the defined cross sections. This water surface is used to create 3d images, movie files of flight or walks down the river, cross section plots. river profiles and plan drawings coloured and contoured by depth.

Historical flood data can also be presented in 12d Model using the "river mapper". This interface creates a water surfaces from existing water level data. The interface uses "shape strings" to add incredible power and flexibility to the mapping process. Meandering streams and off line storages can easily be mapped without burdening your hydraulic modelling package with additional cross section calculations.

The 12d Model Rivers modules read numerous data formats including HEC2 data, EEBY cross section data, USGS DEM formats and xyz data. The add on AutoCAD DWG/DXF and Microstation DGN modules enable existing drawing/elevation data to be imported to 12d.

Elevation data can be combined from several sources and manipulated to form a final ground surface from which cross section data is created.

The modules generate cross sections, measure channel and overbank distances, mark left and right bank locations and automatically mark levee locations for HEC RAS. User specified steady state discharges and Manning's "n" values are exported as initial starting values.

Raster georeferenced images (which can exceed one gigabyte in size) can be used as backdrops for defining your river bank locations. For simple projects, channel improvements are easily designed and volumes calculated using 12d Model Base. Complex designs and volumes may require other modules.

The Rivers modules are:
HEC RAS Advanced, XP SWMM & MIKE 11

These river interface modules work on branched river systems. The complete project is created for the river design programs and for unsteady flow conditions. The maximum water levels are read back into 12d Model.

UNET
In addition to cross section data, this module also exports reservoir storage areas.

ISIS
ISIS has the most comprehensive interface of the Rivers modules. Volumes for online and offline reservoirs are exported and cross sections are created for spill sections as well as river cross sections.

Urban Drainage

The Drainage module allows the design of drainage networks, typically those required for new land subdivisions and development projects.

The drainage string itself consists of manholes, joined by straight or curved pipes. Invert levels and pipe grades can be set or modified graphically or by typed input. Manhole and pipe sizes are also user definable.

Drainage design can be as simple or complex as the project dictates. 12d automatically determines pipe grade based on minimum slope and cover while services clashes are displayed graphically. Data is exported to the design packages Drains, PCdrain, XP-SWMM, XP-UDD, RAT2000, RATHGL, ILSAX, WINDES (Micro Drainage) and spreadsheets. The data exported can be as simple as catchment areas or as advanced as pit inlet capacity and overland flow (determined inside 12d by measuring road cross fall and grade). Even maximum ponding levels and volumes can be determined for inlet in SAG inlet conditions.

Results from the design packages can be read back into 12d enabling the user to....

• update 12d with the new inverts and pipe sizes from the drainage design software.
• plot customised drainage long sections with service crossings, hydraulic grade line, flow, velocity and/or user defined data. Services that cross the drainage pipe and those within a user defined corridor (parallel to the pipe) are also included.
• plot customised plan drawings indicating catchments, pipe sizes and types, inverts and more.
• print pit construction schedules in predefined or custom formats.
• produce pit/pipe quantity schedules by pipe sizes, depths, types etc (all custom defined).
  detailed excavation volumes reflecting pipe sizes, over excavation for bedding materials and user defined trench shapes. Volumes by depth can then be calculated using the 12d volumes package.
• calculate and display/plot flooded areas from overflow volumes or overland flow discharges (normal depth calculations).
• create HEC RAS project files for detailed backwater calculations in critical areas.

Sewer - Waste Water Reticulation

The Sewer module is an extension of the Drainage module and supports the design of gravity operated waste water reticulation systems, typically those required for new land subdivisions (estates) and development projects.

The user enters proposed manholes, pipelines and end of line points. Obstructions which pass over, under or parallel to the design lines within a user specified corridor about the design line will be shown on long and cross section views.

When satisfied with the design invert levels, connections from the design line to the individual house blocks can be added and reported on.Earthwork volumes for trenches can be calculated along the selected design line.

The special waste water reticulation longitudinal plots show existing surface, manholes, design pipelines, pipe grades, property connection points and all obstructions. Long section plots to the Melbourne Water standard are included.

Pipeline

This module is used to support the design of major pipelines of any diameter (for example, 2000 mm) and any length.

The module allows for the extraction of long sections and cross sections against the digital terrain model for the proposed route, plus all the obstructions that run parallel to or cross a corridor of user given width on either side of the centre line of the route.

The joint deflection for pipes of a user nominated length is calculated and interactively displayed along the pipeline.

Earthwork volumes for trenches can be calculated along the selected design line.

The special pipeline longitudinal plots show the existing surface, design pipeline, depth of cut or fill to pipe invert, percentage grades and vertical curve data or deflection angles, and all obstructions.
