Abstract [en]

Geotechnical engineering work contributes to the total environmental impact and monetary cost occurring from the construction sector. Decisions made regarding geotechnical engineering aspects have a profound effect on the environmental impact and the monetary cost of the structure during its life cycle. Life Cycle Assessment (LCA) and Life Cycle Cost Analysis (LCCA) are established methods for assessing the environmental impacts and monetary cost from construction works. This paper presents the results from a literature review of 56 published papers regarding the current situation of the use of LCA and LCCA methods in geotechnical engineering. It is found that only limited research has been published in applying LCA and LCCA to geotechnical engineering structures. Further research should focus on developing a framework using LCA and LCCA for geotechnical engineering structures and also identify and fill data gaps in computer software databases. This would help geotechnical engineers in their daily work to reduce the environmental impact and monetary costs throughout the life cycles of the designed structures.

Abstract [en]

Geotechnical engineering works are part of almost all construction and infrastructure projects. The geotechnical engineering work contributes to the impact on the environment and gives rise to costs throughout its life cycle. Life Cycle Assessment (LCA) and Life Cycle Cost Analysis (LCCA) are established methods for evaluating a product's environmental impact and costs. However, the use of these methods is not extensive for geotechnical engineering works. A literature review showed that there is published research, but as the research topic is relatively new, there are many research gaps. A few topics in geotechnical engineering are better investigated than others and the entire life cycle is often not evaluated, usually only the production and construction stages. Although LCA and LCCA are established methods, the methodology for evaluating geotechnical engineering works needs further development to increase the evaluation work of sustainability aspects. In this licentiate thesis, a methodology is presented of how LCA and LCCA can be integrated into the geotechnical design process. The integration enables changes to the geotechnical design to further reduce the LCA and LCCA result, which is presented in the methodology. The methodology also presents a way to evaluate the possible geotechnical designs to select the most sustainable design based on the LCA and LCCA results. The thesis also presents the performance of LCA and LCCA for geotechnical engineering works and solutions to several difficulties that the geotechnical engineer may encounter during the evaluation of environmental impact and costs. 

Abstract [sv]

Geotekniska konstruktioner är en del av i stort sett alla konstruktions- och infrastrukturprojekt. Den geotekniska konstruktionen bidrar till påverkan på miljön samt ger upphov till kostnader under hela sin livscykel. Livscykelanalys (LCA) och livscykelkostnadsanalys (LCCA) är etablerade metoder för att utvärdera en produkts miljöpåverkan respektive kostnader. Användningen av dessa metoder är dock inte stor för geotekniska konstruktioner. En litteraturgenomgång visade att det finns publicerad forskning men då forskningsämnet är relativt nytt finns det många forskningsluckor. Ett fåtal ämnen inom geoteknik är bättre utredda än andra och hela livscykeln är oftast inte utvärderad utan vanligtvis endast produktions- och konstruktionssteget. Trots att LCA och LCCA är etablerade metoder behöver metodiken för utvärdering av geotekniska konstruktioner utvecklas för att öka utvärderingsarbetet av hållbarhetsaspekter. I denna licentiatuppsats presenteras en metodik för hur LCA och LCCA kan integreras i den geotekniska designprocessen. Integreringen möjliggör ändringar av den geotekniska designen för att ytterligare reducera LCA- och LCCA-resultatet vilket presenteras i metodiken. Metodiken redovisar även ett sätt för att utvärdera de möjliga geotekniska designerna för att utifrån LCA- och LCCA-resultaten välja den mest hållbara designen.  Uppsatsen redovisar även utförandet av LCA och LCCA för geotekniska konstruktioner och lösningar på ett flertal svårigheter som geoteknikern kan påträffa under utvärderingen av miljöpåverkan och kostnader.
