SHN Civil Engineering Services

SHN’s civil engineers are practical, efficient, and collaborative; they are comfortable in the field and in the office. Their design experience is enhanced by cross-training in SHN’s materials testing laboratory and by performing construction observation on projects they have designed.  This field experience is invaluable, and all newly hired engineers quickly become certified to perform compaction testing, allowing them to be immediately useful in the field.  SHN engineers foster relationships with construction company staff, regulatory agency inspectors, and other contractors working on site.  This “real world” training and experience sets SHN apart from most other design firms and informs SHN’s approach to design and construction.

“Real world” experience is also invaluable as more project data is gathered remotely through unoccupied aerial vehicles (drones).  Licensed engineer review is imperative and will continue to be key in our quality assurance program.  SHN engineers’ uses of technology are appropriate for our clients’ sizes of projects; for example, entering field data into tablets allows real-time initial analysis in the field and decreases the potential for in-office data entry errors.  Annotating design sheets in the field is another example of adopting new technology to improve efficiency.  Electronic review and approvals of design sheets allow for better tracking of design assumptions made in the field.
