Brosnan's mission is to understand and deliver on the unique needs of each client.

Careful Planning

Remediation is rarely straightforward. We set out solid plans, flag risks early, and work through the unexpected without losing momentum.

Communicate Early

Good relationships keep projects moving. We don’t wait for problems, we keep everyone informed from day one.

Build Better

Whether we’re repairing or constructing from the ground up, we set our sights beyond compliance, on quality construction that lasts.

The Brosnan story

Founded in 2010, Brosnan was built to last. Born from a desire to do better and leave the industry in a better place than we found it. From our first major remediation project to leading the way in upgrades, refurbishments, and asset management, our mission has always been the same: to restore confidence in construction and deliver lasting value to clients and communities.
