Walker Auto Storage

A hybrid structure — hot-rolled steel frame carrying cold-formed trusses and joists — for a two-level auto storage facility on deep foundations.

The Problem

Long clear spans for vehicle storage want heavy structural steel; economy wants light cold-formed framing everywhere else; and the soils demanded deep foundations — the design had to blend all three into one buildable, permittable package.

What TCE Did

  • Designed the hot-rolled frame — W-shape beams and columns, HSS mezzanine framing, and baseplates
  • Engineered the CFS roof truss and floor joist packages with fabrication-ready detailing
  • Designed reinforced concrete pile caps to ACI 318 and carried the S-001–S-302 sheet set through review
