AB  - The purpose of this paper is to report the results from the second, third, and fourth year of measurement of performance metrics set by Building 2030 consortium. The first year of measurement was reported in the International Group of Lean Construction Conference 2022. The broader question the authors are seeking an answer is: Lean construction practices have been trained, tested, and implemented for many years in the Finnish construction industry but has the industry improved performance?”
During the measurement period the number of projects included in measurement has increased.  All metrics related to reliability have increased during the measurement period; considering the unexceptional environment with the pandemic and an overheated construction market, the authors were expecting a decline in these metrics. There has been an emphasis on decreasing project duration through implementation of takt production. It was interesting to notice that this has not yet been reflected on average durations, likely because the average project size has increased. Also, all sustainability metrics have improved. In conclusion, the industry seems to be improving performance but longer time intervals of robust data will be needed to identify a trend. The Building 2030 consortium intends to continue to annually collect the performance metrics.
