Discover the history of McMillen Engineering, Inc—our roots, milestones, and growth over the years as we've built a reputation for quality and reliability in civil engineering and land surveying. COMPANY HISTORY About McMillen Engineering, Inc. "The sum of our contributions must exceed our rewards." - Terry McMillen, Sr . Terry E. McMillen, Sr. founded McMillen Engineering Inc. in 1977. It was a rather humble beginning as Terry and his wife, Denise, began by converting a portion of the family room in their home into office space. The early years required long days, a lot of work and dedication as the company grew steadily. They soon realized the need for an office outside of their home and moved into their first ‘official’ office in Hopwood, Pennsylvania. They stayed at this location for a few years, then moved to the Hopwood Center for more office space. The company’s continual growth led to the construction of a new office building in the Fayette County Business Park on Wayland Smith Drive, just west of Uniontown. It was their 25th year in business and it was a great way to begin the second twenty-five years. Since 1977, McMillen Engineering Inc. has provided a wide spectrum of civil engineering, but the consistent focus from the first project at Todd Farm until today has been land development. The initial projects were a variety of residential developments followed by commercial/light industrial projects and then large-scale retail developments. As the needs and opportunities of society changed, they expanded services to include infrastructure (water and sewer), design of sewage treatment plants, sewerage collection and water distribution systems, structural design, environmental engineering, and traffic engineering. We believe that education - at all levels - provides growth opportunities not only personally and professionally, but also collectively as a society. This philosophy led us to several collaborations with community partners to provide informative workshops and trainings for colleagues and local professionals. In addition to ensuring professional development among our team and within the engineering and surveying professions, we remain involved in educational programs for students throughout Fayette County.

McMillen Engineering provided culvert engineering services for the Fayette Springs Culvert Replacement, improving road safety. We offer expert erosion control and stormwater solutions for infrastructure protection. CIVIL ENGINEERING CULVERT REPLACEMENT CULVERT ENGINEERING SERVICES The Fayette Springs Culvert Replacement project in Wharton Township, Fayette County utilized funding through the Low Volume Road Program and new technology of the Express Foundation system - the first of its kind to be installed in Pennsylvania. The project spanned approximately 18 feet on Fayette Springs Road and crosses Big Sandy Creek, which is designated a high quality cold water fishery (HQ CWF). Project scope for the Culvert Replacement Project: Engineering Design for Culvert Replacement Preparation of Permits and Compliance with DEP Standards Stormwater Management Implementation Environmental Protection Planning Coordination with Local Municipalities and Funding Agencies CULVERT REPLACEMENT OVERVIEW The existing culvert was undersized and often flooded in heavy rain events, resulting in a public safety issue requiring the roadway to be closed to the public. Temporary measures were taken to open the roadway while a permanent solution was sought. The original culvert had a splash discharge, which was detrimental to the functioning of a High Quality Cold Water Fishery stream because it prohibited the migration of fish upstream, and therefore did not meet the current DEP standards. McMillen Engineering, Inc. proposed the use of a Contech Aluminum Box Culvert with an open bottom utilizing an Express Foundation system. This solution saved money, but also minimized the time that the road was closed. This once flood prone area has weathered recent storms without incident. Wharton Township now has a structure that has improved the health and safety of the residents while allowing native brook trout to migrate north towards the headwaters of Big Sandy Creek helping to preserve the native brook trout for generations to come.

Through collaboration with Fayette County, McMillen Engineering completed the Fayette County Courthouse retaining wall, enhancing safety and infrastructure. Contact us for structural design, stormwater management, and erosion control services near you. MUNICIPAL & COUNTY FAYETTE COUNTY COURTHOUSE RETAINING WALL STORMWATER MANAGEMENT AND EROSION CONTROL McMillen Engineering, Inc. collaborated with the County on an extensive project aimed at enhancing the infrastructure and safety of several key areas. The centerpiece of this initiative was the replacement of three aging retaining walls, which were crucial for stabilizing the surrounding terrain and ensuring the safety of nearby structures. Project scope for the Fayette County Courthouse Wall: Base Mapping Preliminary Site Plan Stormwater Management Plans Erosion Control Construction Engineering and Inspection MUNICIPAL PROJECT OVERVIEW In addition to the retaining walls, the project involved comprehensive improvements to the parking lot. This included not only resurfacing and reconfiguring the parking spaces but also replacing the concrete curb and sidewalk to ensure they met current safety and accessibility standards. As part of the stormwater management plan, the installation of storm inlets and piping was a critical component, designed to improve drainage and prevent flooding during heavy rainfall. The implementation of these systems serves as crucial steps for erosion control. Furthermore, the project included the installation of electrical conduits for gates and lighting, which enhanced both the functionality and security of the area. Landscaping efforts were also undertaken to improve the aesthetic appeal and environmental sustainability of the site. Finally, meticulous line striping and pavement markings were added to clearly delineate parking spaces and traffic flow, thereby improving overall safety for both pedestrians and vehicles. These comprehensive improvements not only addressed immediate safety concerns but also provided long-term solutions to ensure the area remains safe, functional, and visually appealing for years to come.
