R02 Project “Products” or “Tools” Contained in a System on


25


Objectives of the System

1. Identify potential technologies for the four Applications. → 46 Technologies

2. Provide current, up to-date information → 8 Tools for each Technology

3. Provide guidance to develop a ‘short-list’ of applicable technologies

4. Provide guidance for project-specific screening

5. Provide an interactive, programmed system

26

System Mandates

The information & selection guidance system should be:

Simple

Functional

Completely populated

Should be easily updatable

Selection guidance should lead users to a short-list of potential, unranked technologies.

27

Value Added

The system collects, synthesizes,

integrates, and organizes a vast

amount of critically important

information about geotechnical

solutions on a readily accessible

website
