When a building requires structural evaluation, the path to a solution can be complex. We help connect the different parties involved in a project by providing the structural engineering information needed to move forward.
We evaluate the existing structure and identify the relevant structural conditions.
We determine capacity, loads, deficiencies, and structural requirements.
Where necessary, we develop reinforcement, repair, support, or other structural solutions.
We provide the reports, calculations, drawings, and letters required for the project.
We specialize in identifying structural problems and developing practical engineering solutions.
In-depth engineering assessments to determine:
Structural safety
Load capacity
Existing conditions
Structural deficiencies
Required modifications
We develop practical engineering solutions for structural repairs, modifications, reinforcement, and new construction.
Detailed engineering documentation for property owners, contractors, insurance professionals, attorneys, and other project stakeholders.
Specialized solutions including:
Roof load qualification
HVAC dunnage
Load rating
Helical pile capacity
Retaining walls
