Mass Timber Monitoring

Solutions for Quality Assurance during Construction and Long-Term Monitoring for Heavy Timber Structures

Our Approach

SMT has been involved in monitoring moisture in some of the most influential mass timber projects in the world.

We’ve helped enable construction professionals to validate significant decisions in design, sequencing, and quality of work by using data recorded during transportation, construction, and during the life of the structure.

Our unique sensors and electronics allow the collection of performance data from critical components, including real-time conditions during construction.

Our Purpose

Why is it important to monitor moisture in Mass Timber?

Greater Risk

Mass Timber is a relatively new material to the market and its moisture induced effects and thermal properties are different than building materials like steel and concrete.

As a result, it is important in the early stages of a material’s adoption into the AEC market to monitor and analyze the building performance.

Retain Moisture

Mass Timber retains water similar to a sponge, which can collect and cause damage to structurally significant portions of the building.

External Conditions

The moisture content of wood components are affected by external environmental conditions and internal sources generated during construction and occupant generated moisture.

Structure Displacement

Mass Timber poses some unique challenges other materials don’t - wood is a hydroscopic material and will expand and contract over time from moisture, temperature and other forces.

Roof Integrity Monitoring

The roof is the first defense against moisture, however there is risk of moisture accumulation due to either errors and damage in the installation of the roof assembly, or through moisture that has been allowed to collect in hidden areas. ​To verify the quality of your roof on a mass timber project, SMT offers Leak Detection Services.

01 Solution

FutureCast Roof Leak Detection System

A permanent network of sensors installed in a grid directly onto the waterproof membrane part of a roof to monitor the integrity of the waterproofing. This allows tracking of moisture content trends over time to allow for scheduled repairs to minimize moisture damage.


02 Solution

Roof Deck Moisture Monitoring

Similar to FutureCast, moisture sensors are installed directly into the structural element of the roof - however they are not installed in a grid. This allows tracking of moisture content trends over time, as well as efforts to dry out the assembly in the event of a leak.

03 Solution

Targeted Structural Monitoring

An array of sensors are installed at the most structurally important locations to monitor for the long term health of the structure as required by the design.

Roof Deck Moisture Monitoring

When working with Mass Timber construction it's important that materials arrive on site dry and stored in a dry environment. SMT monitors timber materials during transportation by installing sensors enabled via cellular based data acquisition to monitor for moisture, temperature and relative humidity.

Moisture sensors at various depths


SMT moisture sensors can be embedded in structurally significant sections of laminated timber, with several probes at different depths to build up a moisture content profile of the section. We can begin monitoring right from factory by inserting these sensors before the timber is sent out.


Sensors can be used to track moisture levels in timber during transportation to ensure materials arrive on site dry. Data is sent wirelessly while timber is in transportation.

Once materials have arrived on site, the moisture sensors can be removed or kept embedded for long term monitoring of moisture content

Data Visualization

At SMT, we are constantly pushing forward with how we visualize data - making it easier to understand and use.

In combination with BIM technology, we utilized the Unity Game Engine to create a virtual tour of the UBC Tallwood Building, allowing users to explore the building and inspect live sensor data.
