our expertise

With increasing frequency, clients remain challenged with improving the management of our impervious environment. With today’s climate change challenges, cleanliness, availability, and quality of water is of paramount concern. Our team of engineers and technicians provide innovative, cost-effective solutions and recommendations for a wide range of water management systems and improvements, including the design of reservoirs, dams, and levees. The management and design of drainage systems for stormwater runoff and the systems needed to manage runoff in an environmentally sound manner is a critical component of almost every site/civil engineering project. With a focus on safety, constructability and lifecycle costs, Patrick is proud to meet these challenges with value-added solutions.

our projects

Chemical Manufacturer | Ditch Erosion Control

Chemical Manufacturer | Ditch Erosion Control

Patrick partnered with a chemical manufacturer to address heavily eroded ditch banks adjacent to an existing industrial access road at their facility. Patrick gathered topographic survey data at each area of concern, performed a geotechnical field investigation to gather soils data, and performed a slope stability analysis of the primary area to ascertain the potential risk. It was determined that, without improvements, the bank was indeed at risk of failure at the primary area. Patrick provided a summary of creek bank improvement options, which included slope re-grading, riprap, gabion baskets, a retaining wall, and others. Each option included a summary of the permitting required prior to implementing the improvements. Patrick prepared a design for 215 linear feet of new sheet pile retaining wall to repair the bank, prevent loss of pavement and gain more pavement for truck safety. Patrick obtained necessary permits, performed construction observation, and prepared record drawings.
