Project details
Engineered temporary falsework and construction support for the Shasta Viaduct bridge structure.

Specialized civil and structural engineering services for bridges and infrastructure projects.
4M Engineering provides specialized civil and structural engineering services for bridges and infrastructure projects. It engineers temporary works and construction support systems across ten states, including Utah, Nevada, Colorado, Wyoming, Arizona, Montana, Idaho, California, Washington, and Texas. The practice designs bridge falsework, crane trestles, excavation shoring, and concrete formwork, and provides specialized services for bridge demolition, jacking, and accelerated bridge construction.
Provides engineered temporary support and earth-retention systems for construction projects.
Temporary support systems engineered to safely hold bridge structures during construction.
Temporary travel and transport structural systems designed to support cranes over rivers, elevated, or uneven terrain.
Engineered shoring systems using steel soldier piles and lagging to support excavation walls.
Engineered earth retention and cofferdam systems designed to safely support deep excavations and control water infiltration.
Temporary shoring systems designed to support trench walls during excavation, protecting workers and utilities.
Engineered formwork and bracing systems designed to shape and support concrete columns during placement and curing.
Custom-designed formwork systems used to shape, support, and contain concrete during placement and curing.
Engineered temporary bridge structures that provide safe, reliable access for traffic, equipment, and crews during construction.
Specialized temporary support systems designed to strengthen and adapt existing bridge structures during retrofits, upgrades, or repairs.
