PND’s structural engineers provide comprehensive structural engineering services to owners, architects, and developers on a wide variety of commercial buildings. PND's structural services include designing and inspection of new structures, evaluating existing facilities, performing seismic hazard analysis for design of retrofits, repairs and improvements to existing structures and facilities.

Oftentimes, PND building projects are subject to the severe loading unique to seismic, cold-climate, and coastal locations. High seismic loads, high snow loads with sliding and drifting accumulation, high velocity winds at exposed locations, and low temperature environments are design criteria that PND deals with on a routine basis. PND designs effective foundation systems for frozen soils and soils around buildings subject to freezing.
