Why a small firm

Senior team leaders on every bridge

The people who sign the report are the people under the deck. No handoff between a field crew and an office that never saw the structure.

A direct line to the principals

You talk to an owner of the firm, not a coordinator. We reply to every inquiry within one business day.

Every report reviewed by a PE

Ratings, element quantities and photos are checked before anything reaches your BrM database.

Where we work

We work across the Mountain West and northern Plains, with locations in Montana and Colorado. We are available to state DOTs, counties, cities, and tribal and private owners in Idaho, Montana, Wyoming, Utah, Colorado, North Dakota and South Dakota.
