Regent’s Crescent - Structural Monitoring CLIENT: MURPHY GEOSPATIAL
How Murphy Geospatial incorporated wireless monitoring into their structural and environmental monitoring program during demolition and construction works for a major redevelopment near Regent’s Park, London
Challenge This was a major redevelopment of an iconic crescent near Regent’s Park originally built in the 1820s and designed by the renowned architect John Nash. The plan was to demolish the existing structure behind the original façade – which was to be completely refurbished – and for the excavation of new basements. The demolition was carried out by specialists McGee and construction undertaken by Midgard, for the client. Murphy Geospatial was tasked with crucial structural and environmental monitoring in and around the site including monitoring the London Underground, as the Jubilee line runs beneath the development and the Metropolitan line runs adjacent to the site. They needed to install, commission and maintain three automated multi stations in a live demolition site in close proximity to operational construction plant and with demolition works underway. They also installed more than 250 Senceive FlatMesh™ wireless tilt sensors in the Jubilee line tunnels, which were maintained throughout the multi-year project.
The monitoring of neighbouring properties, which included medical surgeries and other sensitive facilities, required great thoughtfulness because of the proximity to the demolition and construction works. Real-time data was provided to inform the construction company and all stakeholders to ensure that the agreed parameters were not exceeded and that third parties were protected from any noise and other disturbances to enable the construction works to be carried out on budget and on schedule.
Murphy Geospatial installed the following systems above and below ground: • 3 laser scan station sensors (AMS) • 300 Senceive tilt sensors - 250
below ground and 50 above ground
• 3 optical automatic total
stations and manual back-up survey equipment
• 3 digital image capturing devices • 20 seismic vibration sensors • 10 air pressure and noise sensors • 4 air quality and dust sensors • A wireless data transfer mesh network • IoT data communication facilities and alarm systems • Remote-controlled cameras
