The Build

The 4C installation at Escondido

The project also demonstrated the precision of factory-built construction: windows and doors were installed without field modifications, with openings manufactured to tight tolerances before the components ever arrived on site.

Pre-engineered wall panels

Exterior wall components arrived pre-labeled and ready for assembly, with no on-site fabrication required before they went up.

Zero field adjustments

Window and door openings were manufactured to tight tolerances before reaching the site, so every opening fit without modification.

3-day wall package

Exterior walls reached roughly 75% complete by the end of Day 2 and finished on Day 3, followed by roof framing and interior partitions.

Behind The Build

From factory production to field assembly

From digital design to factory production to field assembly, Escondido shows what 4C SAFE™ looks like when the complete process comes together.
