UNDERGROUND CONSTRUCTION INFORMATION SYSTEM

UCISUCIS

• Store/Manage/Integrate all relevant data of a tunnel

over the whole tunnel life cycle

- design data

- construction data

- maintenance and service data

• Provide data to all

partners of a tunnel project

- via internet

- via intranet

• Support common/suitable

data exchange formats

- still to be decided (AGSML ?)

Goals:

UNDERGROUND CONSTRUCTION INFORMATION SYSTEM

UCISUCIS

• Relational Database Management System

(MS SQL-Server 2005)

- data store

- maintenance

- security

- access

• Domain Specific Applications

- a simple GUI

- data visualization

- O/R mapping

- data mining, fuzzy logic techniques

- virtual reality
