Project GoalsProject Goals
Development of a web-based GIS enterprise system for geotechnical data– Capable of serving the broad needs of
practicing geotechnical professionals– Enable internal and external customers access
to search, input, and export geotechnical information
Flexible to allow for future inclusion of new “modules”

Document Scanning ProjectDocument Scanning ProjectOriginal Estimates (Documents in Warehouse)– 1.5 million 8.5” x 11” documents– 50,300 24” x 36” plan sheets– Value = $500 million
Revised Estimates based on ongoing project– 1.07 million 8.5” x 11” documents– 72,000 24” x 36” plan sheets– Additional 25% “Do Not Scan” (duplicates,
severe damage, etc.)
Document Scanning ProjectDocument Scanning Project

Document Management SystemDocument Management System
1. Minnesota DOT…savings of $20k per year in personnel time to look up borehole information
2. Missouri DOT…savings of $81k/year by implementing electronic field data entry; $20k/year in drilling by utilizing historic data
3. Florida DOT…savings of $250k to $500k in subsurface investigation on a single I-595 project by using existing data
What is the economic value?
4. Ohio DOT…savings of $12M to $24M by using previously collected subsurface exploration data
5. United Kingdom Highway Agency has saved 80% of slope repair cost through proactive maintenance made possible by GDMS

Geotechnical Management System (GMS) Objective:
Develop geotechnical and geoenvironmental data exchange standards.
Hence… TPF-5(111), Development of Standards for Geotechnical Management Systems
The name of these standards is

1. United Kingdom Highway Agency has saved 80% of slope repair cost through proactive maintenance made possible by GDMS ($40M to $50M savings)
2. Proactive remediation of geohazards reduces the number of emergency projects and eliminated the 20% to 30% in construction costs associated with non-bid projects ($60M to $180M)
3. Reduction in liability by using “reasonable prudence” through a systematic approach to remediate geohazard with limited funding.
