When I know I’m commissioning a job designed by Allied Engineering I can be confident that the engineering is sound, the documentation is clear and complete, and that they are willing to listen to feedback and collaborate towards the best design for the client’s needs. I consider Allied a top tier engineering firm and wouldn’t hesitate to recommend them to anyone.

During The Park Danforth’s most recent design of its Arbor Street expansion, Ian McDonald and the team at Allied Engineering brought expert insight and advice regarding the building systems in a way that met our needs and expectations for the living and community spaces that would ultimately become ‘home’ for those who would reside here.
