NDOT Custom Applications

 

BCAP (Broken-back Culvert Analysis Program)  

This program (current Version 4.11c) was developed through research conducted at the University of Nebraska and sponsored by Nebraska Department of Transportation. 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.

 

Bluetops

This .NET application was developed by NDOT staff to produce the printable bluetops construction books. NDOT custom GEOPAK files include two different criteria files, "PGRADE_BLUTOP DIVIDED" and "PGRADE_BLUTOP UNDIVIDED" 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.

 

Box & Leader 

The .NET application was developed to aid designers in creating note box and leaders for plan sets. The application requires the .NET 3.5 framework, and is launched from within Microstation. The application will create a predefined note box height (based on scale) and the designer is able to dynamically define the note box width. The leaders can be drawn at the same time as the note box or at a later point. There are two modes, As-built (fixed color) and Construction, which can toggle through a Microstation key-in. The note boxes are drawn on NDOT predefined levels.

 

Culverts

This .NET application was developed to aid designers in drawing culvert pipe in plan and cross section views. The application requires the .NET 3.5 framework, and is launched from within Microstation. In this dialog, the designer can choose different sizes, materials, and shapes to draw in a dgn file. Once drawn, the user has the ability to modify each element of the pipe independently or as a graphic group. The application will also be able to identify referenced culverts so that culvert extensions can be drawn in the design feature file. There are three different modes that can be toggled though a microstation key-in: Existing, Design, and As-built. Each mode has predefined NDOT symbology.

 

Earthworks 

This custom application reformats the *.log file created by GEOPAK's cross section earthwork process, and creates design file "stickup" sheets required for the plan set. (32 bit and 64 bit support)

 

GPK Tangent 

This application was developed to aid designers in labeling horizontal alignments per NDOT standards. The application requires the .NET 3.5 framework, and is launched form within Microstation with Geopak running (for access to the gpk file). NDOT's alignments are annotated by using both Geopak's D&C Manager and this custom GPKTangent application. The application supports many different types of horizontal alignments ranging from: survey, CD roads, temp roads, ramps and mainlines. All different types have predefined NDOR symbology and can be labeled in 20, 50, 100, and 200 scale.

 

Pavement Grades  

This .NET application was developed by NDOT staff to produce the printable pavement grade construction books. NDOT custom GEOPAK files include two different criteria files, "PGRADE_BLUETOP DIVIDED" and "PGRADE_BLUETOP UNDIVIDED", 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.

 

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 50-yr) of storm frequencies. The program uses the I-D-F curves. Time-of-Concentration method and Runoff Coefficients that are published in the NDOT 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 computer time-of-concentration.

 

ROW Staking 

This .NET windows application is used to create the final ROW Staking report from data extracted from the ROW dgn file. The process NDOT uses for creating staking reports requires that a separate Microstation Visual Basica Application and Geopak Criteria file (part of NDOT's Microstation/Geopak Standards) is run which creates a copy of the row design file, and extracts ROW point data based on Microstation symbologies. The output of this process is a raw data file in text format (*.txt). Once the raw data file has been generated, the ROW Staking application can be used to reformat for printing/delivery; as well as exporting the data to CSV format for loading into survey equipment.

 

Sheets 

This application was developed to aid designers in placing NDOT border sheets. The application requires the .NET 3.5 framework, and is launched from within MicroStation. The application supports all current NDOT plan and cross section border sheets from every division except Bridge. The border sheets are placed in the dgn as references and can be placed at predefined scales. The application has been configured so the designer can place different amounts of sheet labeling.

 

Slope Stakes 

This .NET application was developed by NDOT staff to produce the printable slope stake construction books. NDOT custom GEOPAK files include two different criteria files, "LOC_SLOPESTAKE DIVIDED" and "LOC_SLOPESTAKE UNDIVIDED", 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.

 

Topo Labeler 

The Topography Labeler application has been rewritten by Bentley Systems for use in MicroStation V8i. It is used to place station and offset text in a MicroStation dgn file, labeling surveying utility features.
