The construction industry is relatively slow to move. To have codes in place is key to confirming the research and development required to ensure that the use of the material is safe. I think we're making a lot of progress in that way.
The other side of the equation, as Rick mentioned, is education. It's the chicken and the egg. If there are very few graduates who come from engineering schools that teach wood, there will be few professors who can then go back and teach it. How do you break that barrier? How do you form more engineers and architects?
At the moment, most engineers and architects who start designing with wood are self-taught. I never took a course in timber engineering. I learned it on the job, essentially. However, as the price of timber buildings comes in line with concrete—and I think we're almost there—the demand will grow very rapidly. Then there's going to be a bottleneck on the design side, or on the expertise side in general, not just in design but in manufacturing and construction.
I think we need to prepare for that growth throughout the delivery chain, including in education.
