The Port of Los Angeles is currently in construction of its 2020 plan
expansion. Forecasts have predicted that the port must be able to handle
at least 2.5 times it's current cargo volume by the year 2020. Fupro was
contracted to conduct various geotechnical and environmental studies to
characterize the subsurface, aid in the design of foundations, calculate
dredge volumes, evaluate slope stability, evaluate ground improvement options,
and estimate liquefaction potential. Those tasks were greatly facilitated
by the development of the Underground Geographic Information System (UGIS).
The UGIS, running on the ARC/INFO and ARCVIEW platforms, is a relational
database for storing, retrieving, querying, and displaying data. The inherent
nature of the UGIS is that tabular data can be accessed from the spatial
data such as points on a map, and vice versa the spatial distribution of
the data can be viewed by selecting records in a table. Using the relational
properties of the UGIS, we developed several customized programs for plotting
soil parameters, creating automated cross sections, calculating liquefaction
potential, and estimating dredge volumes. Because of the large volume of
data gathered during the various geotechnical studies, the UGIS was an
important tool for quickly and easily analyzing thousands of data points.
Also, the database was easily expanded to include new data as it was collected
during the various phases of design and construction.
