Design/PermittingGoals Determine most feasible solution based on
specific site conditions Selection and proper sizing of appropriate
treatment Provide buildable construction drawings,
details, specifications and costs Provide engineering/design support and
guidance for unforeseen challenges/situations
Acquire necessary permits and approvals f li bl i

Construction - Safety SAFETY is an integral part of Company
philosophy Our goal to provide a safe environment for not
only the workers, but for the students, staff, faculty and public
Instill the idea that safety isn’t “just a priority”, but should be a way of not only conducting business, but as a way of life
Controlled site access Provided training as needed If unsafe acts were observed, construction
was shut down
