Abstract
Geotechnical contractors install and repair foundations for buildings and large infrastructure projects. Previously, geotechnical companies have typically focused on sustainability improvements on individual construction projects, with a primary focus on improving the environmental sustainability of site operations. However, the activities of geotechnical companies have sustainability impacts far beyond what they do on site. In the context of the UN Sustainable Development Goals (SDGs), whole company sustainability must also address social and economic sustainability. This paper therefore explores all the processes carried out across a geotechnical company, from human resources through to site operations, assessing their impact against the SDGs using a pedigree matrix approach. Through this investigation, we see that geotechnical companies impact every SDG in some way. There is a strong focus on health and well-being (SDG 4) and economic sustainability (SDG 8) throughout a geotechnical company. Some functions, such as procurement, impact a broad range of SDGs, whilst others, such as HR, mostly only impact social or environmental sustainability. Overall, this approach highlights which processes in each function have the greatest impact on the overall sustainability of the company. It also reveals more sustainability impacts than previous top-down approaches. This means geotechnical contractors can better target sustainability improvements in specific parts of their business, making sustainability relevant to each department. It also aims to empower employees to improve the sustainability of their own day-to-day processes.
Highlights
Geotechnical companies offer a broad range of subsurface engineering solutions, from ground improvement and piling, to retaining walls and monitoring [1]
The range of geotechnical solutions offered, materials used and types of construction projects means geotechnical companies have many direct and indirect sustainability impacts to explore. When it comes to improving the sustainability of geotechnical companies, most previous papers have focused on improving design and site operations
Basu et al [3] and Pantelidou et al [4] consider how the design of geotechnical solutions can improve the sustainability of construction projects throughout their life cycle
Summary
Geotechnical companies offer a broad range of subsurface engineering solutions, from ground improvement and piling, to retaining walls and monitoring [1]. The range of geotechnical solutions offered, materials used and types of construction projects means geotechnical companies have many direct and indirect sustainability impacts to explore. When it comes to improving the sustainability of geotechnical companies, most previous papers have focused on improving design and site operations. Basu et al [3] and Pantelidou et al [4] consider how the design of geotechnical solutions can improve the sustainability of construction projects throughout their life cycle They both highlight how many environmental sustainability impacts, from materials use to local air quality, are controlled by foundation design and specific site operations. Other papers have taken this a step further, comparing geotechnical solutions to determine which is more environmentally sustainable for different construction projects [5,6]
