WHY IT EXISTS

Why This Tool Exists

The Problem

Construction teams spend days manually tying and welding rebar cages on jobsites, which is labor-intensive, poses safety hazards, and creates schedule delays. Vertical construction projects waste 5-10% of schedule time on rebar assembly. Renewable energy and infrastructure projects spend weeks on prefabrication without quality consistency.

The Solution

Automates rebar cage assembly at off-site fabrication facilities using proprietary Weaver Workcell robotic systems. Toggle OS converts construction drawings into optimized robotic manufacturing programs. Pre-assembled cages are delivered ready-to-place to job sites, saving 70-90% of on-site rebar installation time while improving quality and safety.
