Laser Scanning and GPR
Location
Montrose, Scotland
Scope
We were engaged by CBRE to conduct laser scanning and a GPR survey at the Baker Hughes site in Montrose. The objective was to provide accurate subsurface and structural data to support critical decision-making for site development and maintenance including; identifying clear areas for boreholes, scanning an unknown area of road within the complex for a suspected underground tank and carrying out scanning and GPR of the warehouse floor to evaluate slab integrity and floor levels. To achieve this, two experienced surveyors were on site over several days, utilising advanced GPR systems and EML tracing to ensure accurate detection and mapping of subsurface features, in conjunction with laser scanning and GNSS topographic surveys.
Solution
This project presented unique challenges, particularly concerning the suspected floor slab settlement within the warehouse. The warehouse team had raised concerns about uneven flooring and potential structural weaknesses. Our approach combined TLS for high-resolution surface mapping with GPR for subsurface analysis. We used TLS to identify areas of slab deflection and measure the depth of unevenness across the warehouse floor. We then utilised GPR to verify these findings and confirm whether voids/cavities/soil condition could be contributing to the problem. We also measured slab thickness to assess load bearing capacity, as thinner slabs are more susceptible to stress from heavy machinery.
We were also instructed to locate a potential underground tank within part of the road outside a warehouse, carry out yard area scanning beneath steel plates for hidden anomalies and service clearance adjacent to the Spitfire test cell to ensure safe excavation and drilling.
Benefits
We produced a heat map of the warehouse floor, which acted as a great visual representation of where uneven sections of slabs were identified along with overlays of identified GPR anomalies from the subsurface survey. Our overall survey data, provided the client with a detailed and comprehensive overview of the focus areas to allow them to make informed decisions on refurbishment and future maintenance.
