tunnel excavation monitoring system

In an age where communication and easy access to information are vital factors for Engineers, Consultants, Stakeholders and Owners for the analysis, interpretation and decision-making, the demand for setting up web-based Integrated Data Management Systems for small and large scale infrastructure projects has increased in recent years. Maxwell GeoSystems has recently developed a module of its MissionOS system, catering specifically to Shaft and Tunnel Excavation works, that is designed to provide timely and sufficient information on instrumentation data combined with construction related works. 

Engineers & Consultants are able to review both instrumentation data and construction progress of excavations for tunnels and shafts against planned progress. The module is also designed to display current excavation levels for shafts, and positions of machines for tunnel excavation works (in both large diameter and micro tunnelling works). All these can be viewed with respect to chainage and geology, both in 2D sections and 3D views. 

The system is also able to reflect the design predictions and the predicted review levels (Alert, Action and Work Suspension), the actual readings recorded to date on site, instrument trend-lines, settlement against location of excavation works and its effect on surrounding sensitive structures, rate of settlement against time, Gaussian plots, contour plots, among others.
