Commercial Alteration Engineering

Engineering for changes to an existing commercial building or occupied space.

What this covers

Understanding Commercial Alteration Engineering

Alterations can affect partitions, openings, equipment and building systems beyond the immediate work area. Share existing drawings and the proposed layout. Include any operational constraints so the engineer can define a coordinated scope.
