"GIS in Engineering"

This presentation demonstrates some new tools being developed by ESRI
that will allow GIS to be used for more powerful engineering analysis
and design.  Although geared towards engineering, public works and
utilities, the tools are generic and can be used for many fields of



GIS is a powerful tool that is underutilized by Engineers and Directors
of Public Works and Utilities.  Primarily this is due to these
professionals using different tools in the past and not having a clear
understanding of the potential of using GIS.  This presentation focuses
on some new tools that can be used for capacity analysis of sewer
systems as well as the design of roadway, drainage, water and sewer


Although these tools are in the development stage, they still have
immediate benefits to engineers in planning, design, and ordinance
compliance verification.  These tools perform simple calculations which
can are very tedious to do by hand.  The following is a brief
description of these tools:


Capacity Analysis:  After setting flow rates per parcel, this group of
tools draws a lateral which connects each parcel to the closest gravity
main then calculates the total cumulative flow in each gravity pipe.
This is an excellent tool for engineers concerned with approving new
developments.  By setting the new increased flow rates, recalculating
total flow is automatic. 


Road Elevation Calculator:  This tool calculates road elevations based
on existing elevation and road slopes set by the engineer.  The
calculation is a simple Existing Elevation + (Slope X Distance).
However, transfer of values from points to lines allows GIS to read the
existing elevation, make a line/slope calculation and transfer the new
elevation to the new point.  GIS knows line lengths so this eliminates
the need to measure in AutoCAD, calculate in excel and re-write in
AutoCAD.  Exporting calculated elevations to AutoCAD is automatic from


Sewer Design:  Building from the slope calculation and transfer tools,
this tool allows the engineer to design gravity sewers.  The user sets
the first manhole, then sets another manhole a certain distance away
(max 400 LF).  The script reads the ground elevation for the first
manhole, draws the gravity main, draws the second manhole then sets all
invert elevations based on preset minimum coverage depths and slopes.
Then the GIS labels all manholes with all elevations separated by


These tools can be adopted to design water and sewer.  Future tools will
include a profile drawing tool for gravity sewer.
