Drainage Design

12d Model provides comprehensive tools for the design and optimisation of drainage and sewerage systems, and other non-gravity services such as gas, electricity, telecommunications and water. 

Integration with the entire civil design and powerful clash detection management allows for efficient 3D modelling prior to, and during, construction.

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…and much more! Fully integrated in 3D with the road design and underground drainage networks. Analysis options available in 1D and 2D.

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. Calculate structure losses, culvert headwater losses, friction losses, inlet capacity, bypass flows and surcharge flows. Optionally supports automatic pipe sizing, partial-area effects, natural channels, diverging flows, reversing flows, weirs, orifices, pumps, tanks and basins. HGL analysis available using the Rational Method and dynamic hydrograph methods.

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.

Design of gravity operated waste water reticulation systems. Model property controls and connections, to better design systems to code.

Non-gravity services & utilities 
Coordinate and grade all non-gravity services and utilities to ensure sufficient cover and clearance for all. 

A variety of string types may be used, including Super string conduits (optionally from Apply Many functions), Pipeline strings, Drainage strings and Super Alignments. 

Designs can be exported to GIS for future reference and use.

Drainage Analysis 
Use Rational Method Hydrology to determine flow rates to each pit and within each conduit, allowing users to perform a hydraulic analysis of a drainage network.

Dynamic Drainage 
Perform detailed hydrological and hydraulic modelling based on volumetric hydrograph methods and hydraulic analysis based on the St Venant equation.

Dynamic Water Supply 
Perform hydraulic analysis and model the water behaviour in pressurised pipe networks consisting of e.g. pipes, junctions, pumps, valves, storage tanks and reservoirs.

Visualisation and Presentation 
Create animated 3D presentations of Drainage 2D results!

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