Our Story

Alteus Building Systems Inc. was founded by Catapulta Contracting Inc. — a general contractor with nearly 30 years of constructing and construction management experience. We are not manufacturers. We are the value-added installer, solution provider and integrator of Prefabricated Superstructure Components & Cold Form Steel Building Assemblies. In collaboration with our manufacturing partner, who produces our systems in a controlled off-site facility, we deliver a complete, integrated service from pre-construction through to precision installation and full project turnover.

Why Build This Way?

We built Alteus because we knew prefabrication only works when the system behind it is airtight — from pre-construction coordination through to the last panel on-site. Every process we follow, every step we take, and every partner we engage is designed to eliminate the guesswork, waste, and coordination failures that slow conventional builds down. The result arrives sequenced, labelled, and ready to install.
