Urban Drainage, Sewer & Utilities

12d Model’s Drainage module offers substantial benefits from conception to construction of piped drainage networks.

12d Model interfaces with powerful drainage software packages to substantially reduce the time needed to design a complete drainage network, and increases design quality through holistic handling of design surfaces, other services, clash checking and trench quantities.

The Features and More Info tabs go into greater detail with regards to the drainage module.

Pipeline

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

This module allows for the extraction of long sections and cross sections against digital terrain model for the proposed route, plus all the obstructions that run parallel 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.

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 sub-divisions 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 sections plots to the Melbourne Water standard are included.

Drainage Layout

12d Model is the tool to create your drainage network. With inbuilt automated pipe grading functions, 12d can optimise your drainage design with the click of a button.

Hydrology / Hydraulic Design or Interface

Hydraulic pipe design can be completed inside 12d’s powerful design engine or exported to other hydraulic design and analysis packages.

Schedules / Results and Presentation

12d Model allows user customisation of results to achieve the highest standard for company and client presentation.

12d Model handles whole projects, not just the roads or drainage requirements, enabling the management of all services, roads, and other surfaces in one system, reducing errors resulting from service clashes or design amendments.

Drainage Layout

Includes:

• Layout your complete drainage network inside 12d with the benefit of cover and invert levels set relative to finished design surface levels.
• Convert 2d cad layouts to 3d drainage networks.
• Automatically set minimum pipe cover and grading.
• Powerful graphics to integrate network layout and vertical grading.  
• Fully optimize drainage networks by user defined grading and invert design parameters. 
• Defines catchments with auto linking to manholes and labeling. 
• Automatic service clash detection and reporting.
• Drainage networks automatically linked to design surfaces so re-designs are catered for.

Hydrology / Hydraulic Design or Interface

The drainage module interfaces with MicroDrainage, Info Works, Drains, ILSAX, PC Drain, RAT 2000, Spreadsheets, XP-SWMM, and XP-STORM. This combines the “real world” power of 12d’s terrain modeling and pipe grading capabilities with other specialised hydraulic design packages.

Analysis results can be brought back into 12d and drainage networks updated automatically.

Flooded widths and roadway depths are shown graphically in 12d. 12d calculates the width of flow using normal depth calculations. For more detailed analysis, HEC RAS projects can be created with discharge results from your hydraulic design program.

Surcharge volumes from drainage pits are difficult to conceptualize. 12d displays surcharge volumes as the flooded area and identifies where spill from the flooded area will occur.

With seamless import/export interfaces with other hydraulic design packages the advanced design and presentation features of 12d can be fully utilised.

Schedules / Results and Presentation

Includes:

• User defined construction setout tables, northing/easting or road centreline chainage/offset.
• Automatic network quantity schedules (pipes and manholes) for pricing.
• Earthwork trench excavation volumes based on custom templates that vary with depth and pipe size.
• Trench reinstatement volumes based on pipe size and bedding.
• Automatic service clash detection and reporting.
• Produces finished/cad quality drawings complete hydraulic data, drawing sheets and title blocks.
