| June 9 , 2004 | 1.8 M | BCAP (Broken-back Culvert Analysis Program) - This program (current Version 3.2) was developed through research conducted at the University of Nebraska and sponsored by Nebraska Department of Roads. It provides hydraulic analysis for steep culverts having one (Single Broken-back) or two (Double Broken-back) breaks in the vertical profile. BCAP uses the same routines as the FHWA HY-8 culvert program to determine headwater depth at the culvert entrance. BCAP then calculates the water surface profile through the entire culvert, using Gradually Varied Flow equations and boundary conditions at each vertical break. The program tests for the occurrence of a hydraulic jump in each culvert segment to help determine outlet depth and velocity. |
| Mar. 12, 2004 | 2 M | RMA
(Rational Method Application) - This program is the automated Rational
Method hydrology procedure. RMA will provide peak flow calculations
for an entire range (2-yr to 500-yr) of storm frequencies. The program
uses the I-D-F curves, Time-of-Concentration method and Runoff Coefficients
that are published in the NDOR Roadway Design Manual, for the state
of Nebraska. The program automates the procedures for computing
composite runoff coefficients and for interpolation of rainfall
intensities using computed time-of-concentration. |
| Sept. 27, 2007 | 1.7 M | Slope Stake This application was developed by NDOR staff to produce the printable slope stake construction books. NDOR custom GEOPAK files include two different criteria files, “LMTU” and “LMTD”, which are processed through the Proposed Cross Section tool within Geopak. These criteria files will create ASCII text files (*.CSV) based on the analysis of the design cross-section graphics. The SLOPE STAKE application will reformat this CSV file and produce the slope stake construction books for printing. This version fixes a bug in the previous issue. |
| Aug. 18, 2005 | 7.8 M | Earthwork This custom application performs a few different tasks. It was designed to reformat the *.log file created by GEOPAK’s cross section earthwork process, and create design file “stickup” sheets required for the plan set. It can also be used to manually enter earthwork areas that were not computed with GEOPAK (hand computed). |

.2M | Earthwork V8 NOTE: This version works with MicroStation and Geopak V8 edition files. |
| May 7, 2007 | 1.5 M | Pavement
Grades This
application was developed by NDOR staff to produce the printable
pavement grade construction books. NDOR custom GEOPAK files include
two different criteria files, “PG_U” and “PG_D”,
which are processed through the Proposed Cross Section tool within
Geopak. These criteria files will create ASCII text files (*.CSV)
based on the analysis of the design cross-section graphics. The
PAVEMENT GRADES application will reformat this CSV file and produce
the pavement grade construction books for printing. |
| May 7, 2007 | 1.5 M | Bluetops
This application was developed by NDOR staff to produce the printable
bluetops construction books. NDOR custom GEOPAK files include two
different criteria files, “PG_U” and “PG_D”,
that are processed through the Proposed Cross Section tool within
Geopak. These criteria files will create ASCII text files (*.CSV)
based on the analysis of the design cross section graphics. The
BLUETOPS application will reformat this CSV file and produce the
bluetops construction books for printing. |
