Every year workers are severely injured or die in unsupported excavation collapses that could have easily been prevented with the use of a shoring system. OSHA outlines specific requirements for trench safety and excavation support, and many times that requires the knowledge and involvement of a professional engineer. DHC specializes in the design and certification of temporary earth retention systems. While the majority of our work focuses on “site specific” engineered plans for particular locations on projects, we are also involved in the design of the trench safety equipment with the manufacturers of trench shields, hydraulic trench jacks, and slide rail system. We are a proud member of the North American Excavation Shoring Association (NAXSA), with DHC president Jasper Calcara acting as the chairperson for the engineering committee.

FEATURED PROJECT
The Willamette Water Supply Project is a $1.6 billion water conveyance pipeline project in Oregon. Pipeline construction began in 2016, and when substantially complete in 2026, will provide fresh drinking water, capable of meeting current and future needs, while ensuring resiliency, protection of public health, and quick recovery during natural disasters and emergencies. Improvement of surrounding infrastructure along the pipeline alignment is an added benefit with much of the work taking place within public right-of-way...
