SYNOPSIS:

Monitoring is a key part of any excavation and one of the major concerns is timely management of the instrumentation data to verify design parameters as development proceeds. As technology is ever changing, data is collected automatically and more frequently, new techniques are needed to manage the data. Recognizing these needs Golder has developed tools to make this possible through an Instrumentation Data Management and Monitoring web based application (GIDIE). This application was successfully implemented on the recently completed Bologna, Italy (1) tunneling project. To compliment GIDIE, a Geo-Engineering Content Management System (GECMS) will be introduced. A one stop web portal designed to aid project designers, construction and monitoring crews to manage all geoengineering and related documentation, instrument monitoring data and spatial data both historically or generated during a project. GECMS and GIDIE have recently been developed and are being implemented on a large tunnelling project in Canada. GECMS integrates three main components:

  • Document Management and Viewing;

  • Spatial Data Management and Viewing; and

  • Instrumentation Data Management and Monitoring (GIDIE). The components are all integrated into a single sign-on framework that allows a user to access information in multiple systems at once within a highly secure environment. The combination of GECMS with the GIDIE module forms a complete geotechnical data management application.

1. INTRODUCTION

Monitoring is a key part of any excavation and one of the major concerns is timely management of the instrumentation data to ensure safety and to verify design parameters as development proceeds. As technology is ever changing and now that data is collected automatically and more frequently, new techniques are needed to manage the volume of data generated. Recognizing these needs Golder has developed tools to make this possible through an Instrumentation Data Management and Monitoring web based application (GIDIE) and a geoengineering content management system (GECMS).

2. REFLECTING ON HOW WE HAVE DONE IT … TO THE PRESENT

The author has been managing instrumentation data on projects in one way or another since 1975. In reflecting on some of the projects that we have worked on we can show the progress that has been made as technology changes. The author has worked on many instrumentation projects and the following is a summary of how data has been managed through the years: On projects in the late 1970's data from instrumentation was mainly monitored manually and then entered into tables, reduced and plotted by hand. Because of the labour intensity of this instrument measurements were made less frequently than they are now. In the early to mid 1980's although measurements were still mainly being taken manually, handheld scientific calculators with programming and plotting capabilities were used to do the calculations and graphing (2). Typically readings would be taken more regularly for the first little while until trends had been developed and then less frequently. Again this was a labour intensive activity. By the mid 1980's data was beginning to be collected by dataloggers and data processed in spreadsheets on early personal computers.
