Structural Engineering

The structural design of a building needs to account for load, seismic movement, and other forces that affect the building envelope and its structural integrity. It is important that your building has sound structural design and materials for its longevity and sustainability.

Allana Buick & Bers (ABB) provides structural analysis, seismic retrofits, maintenance, repair and alterations to hundreds of buildings nationwide. We offer on-site evaluation of structural systems.

Seismic Joint Covers

Probably Maximum Loss (PML) Calculations

Seismic Joint Covers

Seismic joints are continuous gaps between two or more adjacent and connected structures allowing them to move back and forth without colliding in the event of an earthquake. We specialize in the proper design, selection, diagnosis, and remediation all types of seismic joint covers to allow the buildings to move freely in three dimensions, relative to each other, while remaining watertight.

Probably Maximum Loss (PML) Calculations

The seismic risk of a structure is the combination of the seismic hazard at the site (the seismic zone where the building is located and the building’s proximity to known active faults) and the seismic vulnerabilities of the building based on its construction. ABB can provide an accurate Probable Maximum Loss (PML) rating for your building. The PML is an estimate of the cost to restore the structure to pre-earthquake condition, expressed as a percentage of the replacement value.

For example, a 20% PML means that after a given level of earthquake, the cost of repairs is 20% of the replacement value. A building with a 20% PML and a 20% replacement value would have a cost of $200,000 in repairs in that earthquake.
