Murphy Geospatial UK Ltd carried out a structural analysis survey, on nominated structural elements within a building in Central London, using non-intrusive and intrusive testing, on behalf of the client.
The purpose of the survey was to determine the construction details of the reinforced concrete frame elements, including beams, columns, slabs, and walls. The construction details to be determined are the external size of the elements, reinforcement layout and variations within, and any other details related to their construction.
The investigation was undertaken on all levels, from the Basement to the Fourth Floor. The results of this survey will be used to help to plan future work.
Our work: The survey was undertaken using a combination of non-destructive testing (NDT) and intrusive investigation methods. A NDT survey is based on a High Frequency Impulse Radar method (HFIR). This method allows to resolve anomalies within the material below the ground surface. Electro-magnetic energy in the form of radio waves is sent into the ground via a transmitting antenna. The energy propagates throw the different materials encountered as a function of their electrical properties, which is in turn function of their physicals and chemicals properties.
Intrusive investigation comprised of:
• Core drilling within the concrete elements
• Breakouts into the concrete elements
• Depth of carbonation testing
• Dust samples collection for chloride content analysis
