Coordinate Conversion

Convert from State Plane or UTM toLatitude/Longitude or vice versa

Converts when either Latitude/Longitude

or North/East fields are blank

Security Tool

Allows users to customize gINT interfacedepending on the role of the user

Interface can be adjusted by:

Project Purpose (project type)

Role based on Windows Login/Domain


8/49

Security Tool Features

Tailor the user interface to fit usersspecific needs

Set permissions to limit the data to which

they should have access


9/49

Validation Rules

Each table has validation rulesPermissions related rules

Add/edit/delete permission

CalculationsN-value from blow counts

Water content from raw data

Liquid Limit, Plastic Limit, soil classification, etc.

Reality Check

Benefits

CPT data is in the database!Provide consistent and complete analysis

Dynamic calculations and reporting

Users can specify values used in correlations& calculations

Report borehole, CPT, VST and lab datatogether to facilitate comparisons


15/49

Other Practical Applications

Correlate Su (CPT) with Su (VST)Correlate Su (CPT) with Su lab tests

Query CPT to find problematic materials

based on SBT, Probabilistic or FuzzyParameters


16/49

Pile Load Test Data

Pile Load Test data is in the database!(instead of Excel files scattered all overthe network)

Supports comparing pile load test datawith investigation data from CPT,Borehole, VST, and lab testing

Historical Data Cleaning

Raw CPT data files with latitude andlongitude in various formats

Existing borehole data in gINT with latitude

and longitude in various formatsOverloading data fields (N-Value, Blowcounts, UU Triaxial)

Existing borehole data without coordinates


43/49

Historical Data Cleansing

Existing CPT data without coordinates orwith coordinates in another file format

Scanned boreholes without coordinates or

with coordinates in another file formatIncorporating scanned borehole logs intoPLog Enterprise


44/49

Historical Data Cleansing

Nonsensical coordinatesConflicts between coordinates in 03-1GTproject and current project

Projects in English/Metric units

Duplicate data

Duplicate Project IDs

Text data that should be numeric


45/49

Historical Data Summary

1645 point locations

Hole Type Number of Holes

Scanned Boreholes 153*

Scanned Boreholes with Estimated Location 35*

Legacy gINT Boreholes 297

CPT Soundings 1080

CPT Soundings with Estimate Location 11

Boreholes in new gINT Format 69

Conclusions

A comprehensive geotechnical datamanagement system was configured forLADOTD

Utilizes RAPID CPT, PLog Enterprise, gINT,ArcGIS Server, Flex & ASP.net technology

Data entry, reporting, archiving, & retrieval

is now standardized & automatedRetrieval via map interface in ArcGIS 9.2,9.3 & 10.0 or web-based ArcServer


47/49

Conclusions

Built upon 03-1GT and 06-6GT projectsto create a reference resource

Aid in evaluation of site data

Allow for more accurate and cost effectivedesign decisions

~$20,000,000 of geotechnical data was

standardized and archived into thedatabase
