Monitoring installations are crucial for buildings which are subject to vibration, ground movement, extreme weather conditions and construction activities. It is important to detect movements, vibrations, structural changes and responses of buildings to these local conditions in order to identify potential failure modes.

Monitoring provides the information needed to support a safe living and working environment by continuously verifying the ability of buildings to perform their intended function. The growth in the number of tall buildings and MRT(Mass Rapid Transit) projects requiring the construction of tunnels beneath buildings results in an increased demand for building monitoring.

Activities associated with deep excavations can cause ground movements, vibrations and shocks that affect buildings within the zone of influence of the excavation.

Pre-existing conditions in buildings adjacent to deep excavations must be determined prior to excavation commencement by baseline monitoring and structural assessment. Piling operations employed within the excavation, particularly impact, explosion or vibration piling are further sources of potential structural damage.

It is important to detect movements, vibrations, structural changes and responses of buildings to these local conditions in order to identify potential failure scenarios. Managing the risk of infrastructure damage caused by the excavation operations in dense city environments is a major challenge for civil contractors, one that is directly addressed by the installation of a structural monitoring system.

“This ongoing project has enabled us to refine our monitoring techniques and they can be applied to other projects that could benefit from precise Trimble real-time monitoring.”

“The (Trimble 4D Control Monitoring Software) system has already proved itself several times providing vital information for the construction company using the data.”

“We initially used the UPG Monitoring As A Service (MAAS). Along with our on-site surveyor, their team of experts commissioned and managed the system,” said Hutchinson Builders’ project surveyor Andy Rivers. “Using MAAS allowed us to have a system deployed and operational, and we could be trained at a later date before taking ownership. After a few months of seeing the long-term benefits, and because the Trimble 4D software is so user-friendly, Hutchinson’s can easily use the system on future developments for monitoring after this project is completed.” Rivers continued, “UPG was easy to deal with, met our tight time frame for deployment and provided an active crane monitoring system with results accessible to any interested party anywhere in the country. The roll out and commissioning was seamless and allowed for operations to continue on-site as planned.”
