Earliest CAD Drawing - I drew this detail in 1987 in the second half of Auburn's engineering drafting course. The first half of the course was
mechanical drafting the old way, by hand. The second half we used AutoCAD, probably version 2.5 or so.
Using GIS for an Erosion Control Project - This project used topographic, building, vegatation, and drainage data from Ft. Benning's AM/FM to design a re-grading and erosion control project to fill two dangerous gulleys that had developed behind family housing units on the base. The storm
drainage pipe (the two gray lines near the top of the image above connected by the gray circle symbol showing a manhole inlet) carry runoff from the adjacent
street and parking had created two dangerous gulleys in the hillside behind the housing units. Over the years the runoff had eroded the soil on
the hill side that were hidden in the dense trees and undergrowth. A child was hurt when he suddenly fell off the edge of the gully while exploring
the in the woods behind the housing units.
Construction Details - The details above are isometric schematics of a valve configurations connecting to a chiller (what is a chiller?) and the details below show the construction requirements for
the enclosure to be built around the chiller.
