Stantec

This award recognises a hi-tech advancement or concept that has helped a company improve its performance or delivery of a specific challenging element of a project, between January 2022 and January 2023. This category is not aimed at projects that have achieved overall excellence – such projects should be entered into one of the six project categories. The entrant may have achieved technical excellence through producing a new approach to analysis or design, advanced techniques or procedures during design or delivery and/or working with its customers to improve delivery of a specific part of a project through technical refinement. An entry should be for a single technical advance or development applied to a specific part of a project. Developments applied to a number of projects may be better placed in the Digital Innovation or Equipment Innovation categories. The geotechnical work on the project presented must be completed at the time of the submission.

Historic coal mine treatment works to facilitate residential redevelopment at Anstey’s Road, Hanham, Bristol

Stantec utilised Measure While Drilling equipment and the three-dimensional ground modelling software Leapfrog 3D Works to optimise the ground treatment works on a site prone to historical coal mining in Hanham, Bristol. The data was digitally recorded and relayed from the equipment fitted to the drilling rigs providing a detailed log containing multiple parameters to millimetric precision for each individual hole. The data was processed, analysed and imported into Leapfrog to develop and continuously update a three-dimensional ground model of the site to gain a detailed understanding of the ground conditions as drilling progressed and thereby direct the works accordingly. This proved vital in the geological model interpretation as the site is underlain by several unrecorded coal seams and mining features. These were subsequently identified, delineated and treated with the works optimised through the deployment of digital technology to record and model ground conditions in parallel with grouting operations.
