Logistical Coordination in an Infrastructure Project for Better Utilization of Excavators (English)
Abstract [sv]

Detta examensarbete har utförts på högskoleingenjörsprogrammet för Byggteknik och Design vid Kungliga Tekniska Högskolan i samarbete med Svensk Bygglogistik AB. Arbetet diskuterar betydelsen av byggnadslogistik i ett infrastrukturprojekt för att uppnå en högre utnyttjandegrad för grävmaskiner med stöd av logistiksamordningsverktyg.

Sammanlagt har 2150 mätningar utförts under två veckors tid för att kartlägga utnyttjandegraden för en bandgrävare (EC250CL) och en hjulgrävare (Atlas 1505M) på ett referensprojekt i Stockholmsregionen. Resultatet har sammanställts separat för de olika resurserna genom att redovisa och analysera andelen outnyttjad tid och de bakomliggande orsakerna till den outnyttjade tiden.

Resultatet visar att utnyttjandegraden för bandgrävaren är 53 % och 59 % för hjulgrävaren vilket tyder på att ett förbättringsutrymme finns.

Avslutningsvis diskuteras rekommendationer för hur användning av logistiksamordningsverktyg kan utökas inom anläggningssidan.

Abstract [en]

This thesis is written as a concluding project at the programme of Constructional Engineering and Design at KTH Royal Institute of Technology in cooperation with Svensk Bygglogistik AB. The thesis discusses the significance of logistical coordination in an infrastructure project in order to achieve a more optimized use for excavators by using logistical planning tools.

2150 measurements have been documented under a two week period at a reference project in the Stockholm region in order to achieve a valid and representable result for the utilization of two different excavators with varied attributes and prerequisites. The results have been summarized separately for each excavator showing the proportion of unutilized time, the proportion of reasons behind unutilized time as well as the relationship between unutilized activity and time.The results show that the utilization rate is 53 % for the excavator of model EC250CL and 59 % for the excavator of model Atlas 1505M. This clearly indicates that there is a span for improvement.

As conclusion recommendations are discussed of how to increase awareness and use of logistical planning tools for infrastructure projects.
