25 What is the economic value? 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

26 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

27 Future Goal Can documents have a spatial component? Geo-referencing Documents

35 Ohio DOT Specifications for Geotechnical Explorations

36 Modifications to the SGE Reflect the new standards Implement Electronic Data Deliverable (EDD) Identify the requirements for the electronic submission of data

37 DIGGS: Transportation Pooled Fund Project 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 Data Interchange for Geotechnical and Geoenvironmental Specialists (DIGGS)

51 What is the economic value? 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.

52 A A key element in a successful system is the ability to easily and efficiently share geotechnical data. (EarthSoft,, 2007)

53 What Does Our Future Hold?

54 Data Management System Pilot Project PC version of Application Testing Enterprise Application

55 How is EarthSoft Implementing DIGGS? 1. Intelligent Data Entry Form (IDEF) that creates DIGGS format data files DIGGS XML/GML File

56 2. The EQuIS Data Processor (EDP) will check DIGGS files, applying validation rules Errors highlighted EDDs with errors highlighted Valid value not found, select correct value from pull down menu Required field not populated, make correction

57 3. EQuIS will import DIGGS files using EDP DIGGS XML/GML File EQuIS Data Processor (EDP) EQuIS

58 How is EarthSoft Implementing DIGGS? 4. EQuIS will export data in the DIGGS XML/GML format EQuIS DIGGS XML/GML File
