Structural Engineering

Existing, unusual, damaged, or simply not standard.

Structural engineering for buildings, foundations, steel, concrete, masonry, specialty structures, equipment, repairs, and field conditions that do not fit a canned detail.

Structural services

Design, evaluation, and problem solving.

DRJ works on both new and existing structures, from focused component checks to complete structural systems. The work often starts with a practical question: what is there, what is wrong, what must carry the load, and what is the cleanest way to fix or build it?

Foundations + footings
Steel framing
Concrete structures
Masonry
Residential evaluations
Repairs + strengthening
Specialty equipment
Custom structural analysis
Specialty work

Sometimes the right analysis does not come in a software menu.

01

Existing Structures

Condition review, load-path evaluation, field measurements, repair concepts, and structural recommendations.

02

Specialty Structures

Lifting devices, equipment, fabricated assemblies, supports, custom frames, and other non-building structures.

03

Construction Problems

Field conditions, substitutions, conflicts, revisions, and practical engineering when construction does not match the original assumption.

Approach

Follow the load. Then follow the construction.

A mathematically correct answer is not enough if the connection cannot be fabricated, the footing cannot be placed, or the repair cannot be accessed. Structural design has to survive contact with the field.

Calculations support the decision.

The engineering starts with understanding the real condition and ends with documentation that someone can use.
