Infrastructure Management

Overview

The majority of my professional career has been in the infrastructure management and master planning arenas. Being able to determine what assets a community has and how to place new assets is a vital role for a planning and real property office.

USAG Humphreys

From 2008 to 2011, I worked in the master planning office at US Army Garrison (USAG) Humphreys, located in Pyeongtaek, South Korea. In my role as GIS/CAD Support Technician, it was my responsibility to map all existing features, such as buildings, roads, sidewalks, and utility lines. Some of the data was digitized from aerial images, CAD drawings, and pdf maps. In addition, I performed field checks to verify features using both visual and GPS observations. These actions ensured the highest level of accuracy of our GIS data.

Another important aspect of this position was to aid the master planning staff with site layout designs. I received a certificate of appreciation for a project I worked on to site a certain weapon system on the installation. The image below shows the certificate I received.

Yongsan Relocation Plan

Another position I held was working for CH2MHILL on the Yongsan Relocation Plan. We were developing the master planning for the US Army’s base realignment for South Korea. This project is the largest base expansion project in US Army history and is a multi-billion dollar project. I worked as a GIS & CAD Analyst, helping to shape the master plan for this base expansion. The original master plan had approximately 200 construction projects that were depicted as squares on the map. As design drawings were developed, it was the job of the GIS staff to replace these squares with the designs' site plans. The figure below shows an example of the difference between the original plan and the resulting site plan.

In addition to entering the design drawings, we had to identify conflicts between neighboring projects. Some examples of conflicts include things like "Do the sidewalks align, or is there a gap between them?" and "Are the ground elevations graded so that neither site will flood during heavy rain fall?" We also had to do temporal conflict detection since many of the projects were being built on sites with existing buildings that will be replaced at a later date. For example, the plan called for building a new barracks on the site of the current medical clinic. However, during my conflict detection analysis, I discovered that that barracks was schedule to start construction 3 years before the new medical center was to be built. This detection allowed the army to delay the barracks until the new medical center was ready, saving about $100,000,000 in penalties and temporary space construction costs.

Reflection

These are only some of the work experiences I have had in infrastructure management and master planning. I enjoy this area of focus since it is like piecing together a large jigsaw puzzle together and is constantly bring new challenges to the table. Likewise, helping decision makers to make informed decision on the best use for limited resources is a rewarding endeavor.
