Tunnel Construction

MissionOS platform has been employed extensively for the management of data on some of the world’s largest urban tunnel projects. Its lightweight footprint gives tunnel professionals ready access to the latest data from borings, design prediction, production data and instrumentation results. Tunnelling and underground construction works contain extensive amounts of data generated from site investigation, instrumentation & monitoring, as well as construction itself. Successful delivery of these projects requires a thorough understanding and interpretation of the information being received in real-time. The MissionOS platform is a market proven system that has been implemented on large urban tunnel projects worldwide for risk management, machine process control, shift reporting and observational engineering feedback. With unparalleled flexibility for data integration and analysis, the MissionOS is proving to be the tool of choice for tunnel professionals worldwide. Maxwell GeoSystems continues to develop enhancements and tools tailored specific to the clients’ needs. Our team of experts in tunnelling, instrumentation and computer programming, work closely with clients to provide solutions for reducing uncertainties and minimising risks on projects. Application : The Forrestfield–Airport Link is a railway line currently under construction on the Transperth network in Perth, Western Australia. The line is intended to service Perth Airport and the Perth foothills with a terminus in Forrestfield. The Forrestfield airport link tunnel is a 5km dual TBM bored passenger rail tunnel project, linking Perth’s eastern suburbs to rail for the first time. The project faces major challenges going forward, with tunnelling under highly sensitive, critical infrastructure such as operational airport runways, and existing rail lines. In addition, the local karstic geological environment poses several tunnelling issues particularly given the terrain. All monitoring data is hosted on the MissionOS system through Maxwell GeoSystems’ partnership with GLS monitoring. TheMissionOS system, along with GLS, the joint venture partner, have both been externally audited and passed by the Perth Transit Authority Airport. There are 32 instrument types incorporated in the MissionOS system scope. These include ground, rail, and structure monitoring points through tilt-meters, inclinometers, extensometers, to vibration monitors, water observation wells, and weather stations. Even battery health for system telemetry is monitored. The configurability of MissionOS data models allows data collection and processing of endless instrumentation types. TheMissionOS Generic Data Loader (GDL) has been set-up to automatically extract data from 400 individual data files from one-off uploads to real-time uploads multiple times a minute. visit : https://www.maxwellgeosystems.com/projects/forrestfield-airport-rail-link-tunnel 1301 Arapahoe Street, Ste 105, Golden, CO 80401, United States
