Welcome to Parkin Engineering

We are structural engineers. We determine the layout and sizing of the framing which supports buildings, bridges, and other structures. We work with owners, developers, architects, designers, and contractors.

For all structures it is advisable to have a structural engineer involved in the design. Structural engineering is usually mandated by the permitting agency for structures other than residential. Some residences, by virtue of irregular plans, size, extensive glazing, or unusual details will need engineering.

We perform calculations based on industry standard requirements for self-weight, live (human), snow, wind, and seismic loads. We also proportion retaining wall systems for soil load recommendations provided by geotechnical engineers.

Industry standard minimum loadings and material strengths are statistically based to keep risks to owners and the public at acceptable levels relative to the cost of construction. They are documented in the IBC Code for buildings, and the AASHTO Specifications for bridges. Risks can usually be reduced further but with increased construction cost if clients wish to exceed code standards.
