Following on from the author’s recently completed doctorial research investigating Scandinavian industrially produced engineered construction methodologies and their potential application in Australia, this paper reports on the research and development...
With the trend towards sustainable building design, timber-concrete composite floor systems attract great interest among building designers and developers as an alternative to the profiled steel-concrete deck that are commonly used in commercial construction. The proposed 2-layer composite floor deck consists of a profiled nail laminated timber...

On tall wood buildings, mass timber elements including CLT, NLT, glulam, and other engineered
components absolutely need to be protected from excessive wetting during construction. This requirement precludes the use of many conventional cladding systems unless the building is fully hoarded during construction.
The building enclosure and façade of UBC Tallwood House consists of an innovative prefabricated steel stud rainscreen curtain-wall assembly that is pre-insulated, pre-clad, and has factory installed windows. Design of connections and air and water sealing of panel joints and interfaces was carefully considered given the tall wood structure they were designed to protect. While steel studs were utilized in the panelized structure, feasible curtain-wall designs were also developed and prototyped for wood-framing, CLT, and precast concrete as part of the project.
Looking ahead, there will continue to be innovation in design and construction of fast and durable facades for taller wood buildings. New prefabricated panel designs incorporating CLT panels and connection technologies from unitized curtainwall systems are already being developed for the “next tallest” wood buildings in North America.
This document aims to emphasize the importance of an appropriate level of on-site moisture management for wood construction, depending on weather conditions, construction methods, and assemblies used. It covers three different but related research projects. It first describes baseline moisture contents (MCs) measured from...
