Automated Storm sewer Analysis & Design (ASAD) is a software package used to design, analyze, and draft storm sewer systems specifically for Florida (USA) roadway projects. ASAD provides tools that allow the drainage engineer to go from raw conceptual design to a finely tuned design and construction plans in hours instead of weeks. Hydraulics

* Up to 1000 nodes per system
* Maximum of 50 systems per project
* Runoff computed using the rational method
* Full and partial flows supported
* Computes backwater curve with junction and exit loss options
* Roadway spread analysis using HEC-12 method
* Time of concentration worksheet, TR-55 and Kinematic wave.

Automatic Calculations
# Pipe sizing
# Pipe lengths (structure center-to-center & actual quantity lengths)
# Inlet / Top / Grate elevations
# Onsite drainage areas
# Pipe invert elevations
Plans Production

* Drainage structure cross-sections drawn
* Storm sewer drawn in plan view
* Profile view of storm sewer with hydraulic and energy grade lines
* Cross section pattern lines drawn at each node location. These lines may be used by other software such as GEOPAK to generate the existing and proposed roadway cross sections.
* Drawings annotated to user specifications
* All plans production tools draw directly into Intergraph/MicroStation CAD format files (*.dgn)

Reports

* Storm sewer hydraulic tabulation
* Summary of drainage structures (drawn directly into CAD file)
* Roadway spread analysis report
* Time of concentration worksheet
* Underground utility conflicts
* Profile elevation report
* Storm sewer cost analysis
* others…
