SCDOT Type 25 Catch Basin Design Aid
SCDOT Type 25 Design Aid is an Excel Spreadsheet that allows users to properly space Type 25 Catch Basins
Hydraulic Study of the South Carolina DOT Catch Basin Type 25
This study documents the CFD modeling of the Type 25 Catch Basin and contains instructions for the design aid.
Inlet Spacing Charts
These charts aid in spacing catch basins on curbs for applications where only roadway drainage is considered. They also take into account maximum ponding and 100% interception.
Alternate Pipe - Consultants - Spreadsheet
The alternate pipe spreadsheet for consultants is for inserting drainage design data into the roadway design CADD files.
GEOPak Specification Support Manual
The GEOPAK Specification Support Manual explains the step-by-step procedure to complete a storm sewer design utilizing GEOPAK Drainage. All standards and conventions are explained as well as descriptions of output reports to be submitted after the design is complete.
The MicroStation cell library was created for use with GEOPAK Drainage. Both MicroStation & GEOPAK (V8 or XM) programs are required to use this file.
The Drainage Library is also used with GEOPAK Drainage. This file references the cell library described above and the .ddb file.
To create our standard output files for GEOPAK Drainage 2004, you will need the following files. The .drf files are needed to generate the .csv files. This data is copied into the blank EXCEL files that contain the standard information in the preferred format that we require to be submitted after the design is complete. Drainage_report.xls is the macro that you will need for the quantity summary reports. See the GEOPAK Specification Support Manual for a complete explanation of the files and how each is utilized.
The .drf files were generated inside of GEOPAK Drainage 2004 and requires Microstation 08.05.02.27 Windows x86 or newer and Bentley GEOPAK 2004 Edition - Version 08.05.02.35 or newer to operate. GEOPAK Drainage 2004 is a subprogram of Bentley GEOPAK 2004 and cannot function without another subprogram GEOPAK Road 2004. Bentley GEOPAK 2004 runs inside of Microstation V8; therefore, both programs are required.
The EXCEL files were created in Microsoft EXCEL 2000. The macro was written in Visual Basic.

Hydrology Data Sheet for Culverts (<20' Opening)
The spreadsheets below are standard submittals for specific circular culverts and all box and arch culverts. They were written in Microsoft EXCEL 2000.
The Federal Highway Administration website provides a download for the HY8 culvert design and analysis programs. You can also download the Hydraulic Design of Highway Culverts manual, which is the basis for HY8.
Roadway Design Manual
The Roadway Design Manual assists technicians and engineers in selecting the needed design criteria in preparing plans for SCDOT construction projects.
