We're entering the final stretch of our latest Soprema project, with the SOPRANATURE green roof system being installed at their new 234,000SF facility in Tillsonburg!๐ŸŒฟ

After completing the same system at Sopremaโ€™s Woodstock facility earlier this year, itโ€™s exciting to see another green roof going in at Tillsonburg. A finishing touch that reduces stormwater runoff, combats heat islands, and supports local biodiversity, itโ€™s the kind of investment that keeps giving long after construction wraps up!๐Ÿ™Œ

Our Finance team traded the office for the job site as they visited our Blackbridge Road project in Cambridge for a firsthand look at the work our crews do every day!๐Ÿ› ๏ธ๐ŸŒ‰

And what a time to visit! Sierra Infrastructure is wrapping up streetlight conduit installation, roadwork, and retaining walls for the new Blackbridge Road, while Sierra Bridge puts the final touches on the new bridge structure. The finish line is in sight, and we canโ€™t wait to share the final result!๐Ÿ™Œ

Project Update! ๐Ÿ› ๏ธ๐Ÿšง
Sierra Infrastructure crews recently completed the installation of a 3600mm manhole, 2400mm storm pipe, and 2100mm storm pipe on Speedvale Avenue in Guelph as part of the Cityโ€™s storm system improvements. With a full road closure in effect, getting to this milestone as quickly as possible was the priority!

Just a little further down the road, Sierra Bridge is simultaneously working on bridge foundation works including micropile installation and concrete footing forming.

There's lots happening on Speedvale Avenue right now and we canโ€™t wait to share more!๐Ÿ™Œ

We thought we'd found them all, but Balaclava keeps giving!๐Ÿ’™

As work progresses into the attic of the former Balaclava Public School in St. Thomas, our crews found even more signatures from past classes preserved on the bricks. Alongside our earlier discoveries from the stairwell, this build continues to remind us that it has always been about the people who called it home.

Weโ€™re proud to partner with Indwell, Flourish, and Invizij Architects to honour the history of this space while building its next chapter!๐Ÿ’™

Sierra Infrastructure is officially on the ground at our new Schiefele Road project in the Region of Waterloo! With high water volumes to manage, the team has been busy establishing dewatering operations, sediment and erosion controls, and a site causeway, while north and south slide rail installation gets underway ahead of pier footing prep.

This is just the beginning for this exciting new project, with Sierra Bridge set to join the scene soon. Stay tuned for more updates as this project gets underway!๐Ÿ™Œ

Project Update!๐Ÿ› ๏ธ๐Ÿ—๏ธ
A significant milestone has been reached at Balaclava Crossing in St. Thomas! The superstructure of the new addition is complete, and the team is now pushing toward building envelope completion and weathertight status while work continues to advance on the existing heritage school.

A huge thanks to Otter Creek Welding, Stubbe's Precast, Middlesex Concrete Forming Ltd., Ridgeline Framing, and Peikko North America for their hard work in helping make this milestone possible. Every step forward brings us closer to 78 units of supportive housing for the St. Thomas community, and we couldn't be prouder to be delivering this build alongside Flourish, Indwell, and Invizij Architects!๐Ÿ’™
