12d Solutions is a software developerspecialising incivil engineering and surveyingsolutions. The first version of 12d Model was released in 1991, both visionaries had worked in the industry for many years and found that the solutions on offer simply were not the most user friendly and that a true customer focus was lacking.
Today, we are proud to say that 12d Model is used in over 65 countries worldwide and our licenses are still growing. It is a solution that can be used by small businesses and individual consultants, through to large organisations.

Key Features

Surface drainage
Create overland flow models. Calculate and display extent of ponding at sags and flooded widths/depths/velocities along overland flow paths. Assess aquaplaning risk on major roads. Highlight critical areas. Fully integrated in 3-D with the road design and underground drainage networks. Analysis options available in 1-D and 2-D.

Drainage networks
Analyse, design, grade and size drainage networks (pits/pipes/culverts/channels). Integrated in 3-D with terrain model, road design, crossing services, and hydrological models. HGL analysis available using the rational method and dynamic hydrograph methods. Use of 3rd party drainage analysis software is also supported.

Storage basin volumetrics
Optimise drainage systems which include stormwater detention basins and storage tanks, with simple statistical methods for preliminary design and sophisticated analytical methods for final design.

Non-gravity services & utilities
Coordinate and grade all non-gravity services and utilities to ensure sufficient cover and clearance for all. Designs can be exported to GIS for future reference and use.

Visualisation and presentation
The 3-D design is automatically/continuously created and can be viewed at any stage of the design process to provide instant real life representation of the project. Walk and drive through the design with options to record the drive as a movie to share with clients and other stakeholders.

Project documentation
Automate the production of reports and drawings (plans, cross-sections and long-sections) and reduce drafting times.
