Alteus Building Systems Inc. was founded by Catapulta Contracting Inc. — a Construction Management firm and 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 multiple manufacturing partners, who produce 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.
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.
Alteus is the installer and integrator. Our manufacturing partner fabricates and assembles in a controlled off-site facility. Clear roles. No confusion on-site.
Quality oversight from design through installation and turnover — with full envelope quality assurance documentation on every project.
Nearly 30 years of overseeing complex projects means we anticipate problems before they occur — especially in pre-construction.
From the Digital Twin to project closeout — one partner, one process, nothing lost between stages.
