The aim of this project was to quantitatively measure the onsite installation productivity of Cross Laminated Timber in multi-storey building projects. Specifically, the work aims to improve an evidence-based understanding of expectations concerning:
1. The speed and productivity of CLT installation.
2. Assumptions when planning CLT processes onsite.
3. Benchmarks to facilitate comparisons between CLT and other forms of construction.
4. Guidance about process improvement on-site.
Multi-storey CLT buildings are relatively new to Australia and so an in-depth case study of a specific building project was the chosen method of undertaking the research. Time-lapse photography was used to gather site assembly information and the resulting footage was converted into quantitative data including the number of worker hours and crane hours used in installing the wall and floor panel areas involved. Statistical analysis was used to derive productivity rates (m2/hour), floor cycle times and other related findings, concerning the installation of CLT.
