Log Construction Practices and Future Outlook: Perspectives of Finnish Experts

Abstract

This paper analyzed practices and future outlooks of log construction from the perspective of Finnish experts through interviews. Key findings highlighted that: (1) interviewed experts emphasized the environmental benefits of log construction; (2) moving log buildings from one place to another was considered a natural way to reuse logs, but several challenges regarding wet areas and incompatibility of different producer profiles were reported; (3) single-material construction of log was stated to have many advantages such as ease of application during erection and relatively long service life; (4) log structures were mostly associated with health, safety, coziness, beauty, and warmth; (5) increasing trend in the use of log construction in large-scale public projects was reported; (6) experts stated that the use of logs in high-rise buildings in Finland is underdeveloped, but hybrid applications using engineered wood products can provide a solution to this issue; (7) modern log cities can be designed with proper solutions, paying attention to several issues e.g., large glass-faced facades; (8) cost competitiveness, familiarity, fire safety, and facade cladding were assessed among the biggest challenges of log construction; (9) issues such as increasing number of contractors specializing in log buildings, robotics in production automation, digitization of manufacturing control were on the future agenda of log construction. It is thought that this study will support the use of logs by contributing to log structures that will be diversified and developed in the Finnish construction market.
