This year, some of the busiest schedules at Tatham belonged to our mini Tathamites!

From baseball in Collingwood and Wasaga Beach to lacrosse and hockey in Orillia, these young athletes kept our staff and their families busy with practices, games and tournaments.

And we loved spotting the Tatham name on the back of a few jerseys along the way.

Congrats to all our players on a successful season and best of luck to those already lacing up for the next one!👏

Sometime between the weekend turkey and pie, a relative will lean over and ask, "So, how's work?" 🦃

At Tatham, it’s one of our favourite questions! And the answer usually comes with a story, whether it's the project we're working on, the people we work with, or the places our work takes us.

15 years of great golf, memorable moments and coming together for local healthcare. ⛳

This year marked Tatham’s 15th year as Title Sponsor of the Collingwood General and Marine Hospital Foundation’s Annual Mad River Classic Golf Tournament.

There have been plenty of memorable moments along the way:
🔹 Teeing it up on Mad River’s beautiful private course each year,
🔹 Dan Hurley proving 2024 was his year with a hole-in-one; and
🔹 Last year’s announcement of our $500,000 commitment to CGMHF.

This year, the sold-out tournament raised more than $75,000 for Tomorrow's Hospital, turning a great day on the course into meaningful support for the future of healthcare in South Georgian Bay.

We’re grateful to have been part of this fantastic tournament for so many years, and even more grateful for what it continues to make possible for healthcare in our community. 💙

As we welcome clients, colleagues and community partners to our office open house, it’s a great time to look back at where we started and how far we’ve come.

Our northernmost office opened in 1997 with just two people. Nearly 30 years later, we’ve grown alongside and , with engineers and designers working on projects that shape the region, from bridges and roads to housing and waterfront developments.

Over the years, our local partnerships have grown, too. In the past three years, Muskoka-based projects have earned two Ontario Engineering Project Awards.
And this year, we completed an expansion that took our space from 3,000 to 6,000 sq. ft., creating room for our growing team and more disciplines to call Bracebridge home.

A few things that make working from pretty special:
🔹 Meeting rooms and offices named after Muskoka's best-known lakes: Rosseau, Muskoka, Hardy and Joseph
🔹 Gary the gopher, our neighbour for nearly 10 years (and the little Garys who join him every spring)
🔹 Site visits and construction projects surrounded by lakes, forests and some of Muskoka’s most spectacular scenery

From the projects to the people behind them, take a closer look at our Bracebridge office ➡️

Breaking ground on more affordable housing in Muskoka.

Last week, we joined Muskoka Community Land Trust , the Town of Huntsville and the District Municipality of Muskoka to break ground at 40 Florence Street West: a 150-home development that will include a minimum of 40 percent permanently affordable housing.

It’s meaningful progress toward expanding housing options in a region where affordability remains a challenge.

The first phase will bring 47 new homes to the site in a four-storey apartment building, with a mix of one-, two- and three-bedroom units. The building will also feature 11 barrier free units.

Working closely with McCallum Sather Architects, Tatham is providing structural, mechanical and electrical engineering for the buildings, including the reinforced concrete foundations supporting the pre-engineered mass timber superstructure, HVAC, plumbing and electrical systems, and overall site electrical design.

With some of our own team living and working in Muskoka, we know how important increasing access to attainable housing is to the region. It was fantastic to see so many community partners come together to mark this milestone and support the project as it moves into construction.

More water capacity is on the way to support Town of Innisfil’s growing communities. 💧

Construction is progressing at the Alcona Reservoir site on a new reservoir cell and booster pumping station designed to keep pace with Innisfil's growth through 2051.

Once complete, the project will deliver:
🔹4,350 m³ of new reservoir cell capacity
🔹+50% more overall storage capacity
🔹Improved water delivery west of 20th Sideroad

Crews have now moved past excavation and foundation work and are forming the concrete structures that will become the new reservoir cell and pumping station.

As prime consultant, led the overall design and project delivery, drawing on eight disciplines: Buildings, Construction, Electrical, Hydrogeology & Geoenvironmental, Mechanical, Municipal, Transportation, and Water & Wastewater.

We’re proud to be working alongside InnServices Utilities Inc. and Jacobs Solutions Inc. to bring this important infrastructure project to life.

📸 Check out the photos to see how the project's coming along.

It may not be the most glamorous topic, but properly maintained septic systems play an important role in protecting our homes, communities and environment.

This Septic System Awareness Week, the Ontario Onsite Wastewater Association (OOWA) is helping homeowners better understand their septic systems and the simple steps they can take to keep them working properly.

As President of OOWA, Tatham Senior Technologist and Project Manager, Bill Goodale joined CTV News earlier this week to share practical advice on responsible septic system use and maintenance.

🎥 Watch Bill's CTV segment to learn how small maintenance habits can make a big difference and follow OOWA for more practical tips throughout Septic Awareness Week
