The Williams Site Civil Difference

About Us

We’re a different kind of civil engineering company.

Williams Site Civil is an experienced civil engineering firm based in Harrisburg, PA. We provide full-service civil engineering services for clients throughout Pennsylvania and deliver exceptional results.

We know that the civil engineering decisions we make at the beginning of the project can have a dramatic impact on the construction and maintenance costs further down the line. At WSC, we act as good stewards of your resources, and take a proactive approach to ensuring that we provide our clients with value-oriented civil engineering services designed to meet their specifications while staying within budget and on schedule.

Every Williams Site Civil project is enhanced by our diverse in-house expertise in civil design, development, excavation and construction. We understand how to make sure that the site is maximized and laid out in a cost-effective manner. Our innovative approach is driven by our direct access to the resources and experience of the Williams family of companies, which provides our team with deep knowledge and understanding of civil engineering, development, excavation and construction.

Our firms work together synergistically to create value for our clients. This combined experience and expertise gives us the insight to identify and understand risks that may occur throughout the life cycle of the project, the wisdom to avoid problems, and the control to keep projects running smoothly so they can finish on budget and on schedule. WSC is uniquely positioned to assist our clients in meeting or exceeding their project goals.

Our Core Values

  • Earn profits by providing value, not simply by completing a project
  • Apply our knowledge to benefit the client every day
  • Practice transparency and educate our clients so they can make informed decisions about how their money is being spent
  • Earn trust through action

Williams Site Civil is proud to be a part of the Williams family of companies, providing value to our clients at all stages of the project and simplifying and streamlining the site design and approval process.

Paul and Drew Williams, both civil engineers by trade, established the first of the Williams family of companies, A.P. Williams, in 1994. Over the decades this firm has earned its reputation for construction excellence through high quality work, transparency, and its customer-centric approach. In 2000, the brothers founded Mainline Excavating to add to the portfolio of services they could offer to their clients, building additional value to the project and providing greater control over the final result.

The driving force behind the Williams family of companies has always been to apply our expansive knowledge and understanding of construction to build high-quality, cost- effective projects that work for our clients. As part of this goal, they established Williams Site Civil in 2017 as a natural extension of their construction expertise. By offering value-oriented site civil engineering services, WSC builds savings into the earliest stages of the project, when many of the most cost-effective decisions can be made.

Today, the Williams family of companies continues to grow. For many years, A.P. Williams had offered development as an enhanced service to its customers. In 2019, Paul and Drew formalized this offering, establishing Williams Development Partners to help our clients through the complex stages of development and financing.

At Williams Site Civil, we understand every facet of a of the project, from initial site evaluation through entitlements, construction and maintenance. This approach provides a synergy that gives the WSC team the ability to identify opportunities to add value and save money at all stages of the project.
