Building safely is about far more than preventing injury by wearing hard hats on site, using ladders correctly and erecting safety barriers. During all stages of construction, including temporary works, it’s also about:
There are many additional challenges that may arise on urban construction sites, including:
having little or no knowledge of the ground conditions under neighbouring buildings and structures;
Piling is another thorny issue. If ground conditions prove tougher than expected, the owners of neighbouring buildings may complain that the piling vibrations are exceeding the guidelines and work will have to stop. Switching to a non-vibration method may be incompatible with the prefabricated piles on site, adding time, cost and frustration to the project.
Monitoring neighbouring buildings while sheet piling.
‘An optimised design and construction process gives you best value for money. Smart and proper monitoring enables you to do that safely.'
Clients are always on the lookout for new ways to shave costs off their project without compromising building safety. Working with a reliable and experienced Geo-data specialist can help them to understand the various optimisation opportunities available within the sub-surface risk environment.
It makes good business sense to mitigate ground risks from the outset. In the Netherlands, for example, Fugro conducted soil tests before the start of a major tunnel-boring operation, then monitored movement in buildings and below-ground assets automatically as the boring machine progressed along its route. The client had 24/7 access to real-time data and the project was completed efficiently and without incident.
For an integrated, efficient approach, clients should choose a company with expertise in monitoring, modelling and consulting to help them identify the most important parameters for the project and achieve improved value for money by minimising uncertainty and optimising decisions. Examples include:
Monitoring results and alarms in Fugro’s Gaia.Monitoring delivery platform.
The ground modelling and monitoring activities described above are incorporated in Fugro’s Ground Risk Management Framework, which provides tailored solutions that help clients avoid the excessive costs associated with unexpected structural movement and overengineered design methods.
