Purpose - There has been several developments in the research field of standalone solutions when collectingactivitylevel parameters required for calculating productivity. Progress has also been made on the topic ofautomatic datacollection(ADC) systems on the topic. Although showing promising results, these standalonesolutions could onlyprovide the data for a fully functional ADC systems if they were combined. Even though thismight be the future ofADC systems, an investigation into the capabilities of commercially existing systems mightprovide valuableinformation about the necessary for such an ADC system to be functional. Methodology - A review of the pilot study, the pre-study and a literature search was conducted in order to establisha foundation of concepts and theory on which the requirements that the PM systems examined were to be judged by.A document study of PM system client reports was conducted as well as several interviews with field experts,system providers and contractors. The findings from these document studies and interviews were then judged incomparison to the requirements established by the literature review. Scope and limitations - This study is concerned with establishing whether or not commercially active PerformanceMonitoring(PM) systems possess the requirements and characteristics of an ADC system with the intent ofcollection parameters to be used for productivity improvement and progression control. The scope is furtherconstricted by looking at such systems in the context of construction excavator loading operations. The thesis is apurely qualitative study and lacks any form of quantitative evidence. The arguments presented only provides thereader with qualitative evidence on the topic. The exploratory nature of the scope demands a qualitativeinvestigation on the topic before any meaningful quantitative study can be conducted on the topic. Results and Implications - The study found that in their current state, the PM systems examined did not meet therequirements. They do not provide the client with the required parameters in an satisfactory capacity and did notexhibit the required characteristics of an ADC system. Although the required parameters could be easily remedied,only a solution of a coordination problem would render the PM systems adequate in terms of characteristics. Theactual solutions of this coordination problem is unlikely due to an misalignment in purpose between the PM systemsand what they are judged by in this study. Although the study found the PM systems inadequate in the context ofthe topic, there was made considerable ground in terms of what is required of ADC system with the proposedpurpose in order to be considered optimal.
