Detailed fabrication input is limited by construction contract type (unless it is possible to engage a mass timber manufacturer during design).

Advice
To address the risk of cost escalation, secure a price early from the manufacturer.
Advice
Timely delivery of CLT from the manufacturer has been an issue, but this is improving. CLT does provide opportunities in BC for local manufacture.
Advice
Dimensional control of mass timber elements is stringent, should be explored and re-evaluated within the boundaries of safety and performance.
Advice
Mass panel installation advice: — Full scale mockup is a benefit, allows best practices to be developed and solutions identified prior to construction. — “Install prefab guardrail systems between columns on the perimeter and pre-determine tie-off points for worker safety” — Manufacturers need to clearly identify and locate balanced panel lifting points. — Pre plan and optimize truck load stacks, delivery schedules and erection sequencing
Advice
Involve the mass timber supplier early. (Small contributions in connection designs can make a difference in erection speed).
Advice
“Constant and frequent communication” encouraged all to take ownership of project and actively contribute.
Advice
Ensure precise prefabrication of structural elements.
Advice
Minimize error possibility by allowing all team members (design, fabricators, manufacturers and all trades) adequate time to have access to a common design platform.
Advice
Steel connectors should be the responsibility of the same party that owns the timber manufacturing scope. They should be modelled at the same time, resulting in the purchase of the correct parts.
Advice
Early discussions should involve all parties: installer, manufacturer, architect, engineer, owner/developer. Design with the people who will build the project, from fabrication to installation.
Advice
Suppliers want to sell you the best option but you need to know what you want first. Bring suppliers in early, but only make decisions once you know what you want.
Advice
Develop and share a water protection plan together with the general contractor. Work with the GC: they care because they have to install. Suppliers may or may not care, and also may not have the necessary facilities (eg. membrane applying station)
Advice
Water damage is a major issue that is not yet adequately solved, and results in schedule slippage. There must be a method to protect the timber products from rain and swelling during construction. Improperly coated connections cause problems.
