1. Discuss the role of the contractor and installer in optimizing mass timber cost efficiency while meeting local code and occupational safety requirements. 2. Highlight how an understanding of manufacturer capabilities can improve the cost-effectiveness of mass timber designs. 3. Review recently completed mass timber projects in the San Francisco Bay area and Pacific Northwest, emphasizing lessons learned related to code and building department approval and project budget. 4. Explore methods of efficient communication unique to the designercontractor interface on mass timber projects and discuss how this communication during construction translates to code-compliant buildings that are resilient and energy efficient.

3. Innovation isn’t necessarily new, but it should always be better—and that’s
certainly been the case for mass timber. Environmental performance, lighter
weight, speed of construction and aesthetics are all cited as reasons for its use
over traditional materials. However, one of the hurdles left before mass timber
can become mainstream is cost. Cost of materials, manufacturer capabilities and
efficiencies, erection processes, pre-planning and the level of prefabrication all
play a role in the final cost of a mass timber project, and yet there is little
widespread knowledge of these topics. This panel of three experienced installers
and contractors will provide insight on the cost of real mass timber buildings in
the US. Preconstruction planning, construction phasing, erection techniques and
lessons learned will all be covered to help building designers assess the viability
of their own mass timber projects.
Course Description

4. 1. Discuss the role of the contractor and installer in optimizing mass timber cost
efficiency while meeting local code and occupational safety requirements.
2. Highlight how an understanding of manufacturer capabilities can improve the
cost-effectiveness of mass timber designs.
3. Review recently completed mass timber projects in the San Francisco Bay
area and Pacific Northwest, emphasizing lessons learned related to code and
building department approval and project budget.
4. Explore methods of efficient communication unique to the designer-
contractor interface on mass timber projects and discuss how this
communication during construction translates to code-compliant buildings
that are resilient and energy efficient.

Each building at Genentech took 2 – 3 days of crane time and
approximately one week to complete the CLT panels at the roof.
The glulam columns and beams were built on the ground as
bents
and were erected prior to installing the CLT panels.
Roof panels: 294 3ply (87mm) SPF panels
Glulams: 304 GLB Columns, 895 GLB beams
Both projects were supplied by Structurlam Mass Timber Corp.
