PKF’s vision is to be the premier employee-owned engineering, construction and management company within our chosen markets--A company that our stakeholders and the communities in which we work view us as integral to their success. We anticipate our stakeholders' needs, create unique solutions, and deliver on every commitment we make.


Established in 1969, PKF initially pursued the Heavy/Highway market, building bridges in New Jersey and Southeastern PA. At the point several years later when federal Clean Water funding was enacted, PKF bolstered its infrastructure capabilities by completing work in the water/wastewater plant market. Coupled with the need to maintain direct control of critical aspects of our work, participation in the plant market quickly lead PKF to establish a separate company, Mark III Mechanical, to exclusively self-perform process mechanical and instrumentation work. In 1979, the two firms merged to become PKF-Mark III, Inc. This remains our official name, though we are often referred to in the industry simply as PKF.


PKF places substantial emphasis on self-performance to expand and distinguish itself as a premier contractor with unique engineering, bidding, construction, and management capabilities not evident in competitors. PKF currently has capabilities to self-perform:

  • Site/civil: MSE retaining walls, excavation, duct bank, utility & process pipe, precast structures
  • Heavy concrete: formwork, reinforcing steel, placing, finishing, spall repairs, precast beam & element erection
  • Foundations: drilled shafts, micro-piles, cofferdams, driven and augered piles, sheeting, tiebacks, caissons
  • Electrical: generators, switchgear, transformers, substations, conduit/cable, grounding, fiber, signals, data, CCTV, security, SCADA, train control, instrumentation
  • Process mechanical: pipe, valves & fittings, pumps, blowers, compressors, dryers, precision alignment, boilers, turbines, filters, and instrumentation/SCADA
  • Heavy hauling
  • Startup, maintenance and operations
  • Various architectural disciplines

In addition to its craft capabilities, PKF has strong experience and capabilities in performing:

  • Project Management, scheduling, constructability reviews, QA/QC functions
  • Alternate bidding and contract formats, including design-bid-build, design-build, unit price, lump sum, and construction management with fee


PKF lives by the following guiding principles in how we conduct ourselves and interface with all Stakeholders. At PKF, we define Stakeholders as our Clients, our Loyal Employees and their Families, our Business Partners, and the Communities in which we work.



Safety comes first and is foremost in planning and executing all aspects of our work. It is an essential value….it is "who we are." Since our Inception in 1968, PKF is "Proud to be Safe."


PKF is committed to do the right thing at ALL times and in ALL circumstances, whether or not anyone is watching. People are treated with honesty and fairness. Our team is uncompromising and predictably committed to honoring moral and ethical principles. At PKF, our moral compass does not waiver!


PKF is Proud of our Heritage as a dynamic Employee-Owned Company and the Advantages and Opportunities it provides our Stakeholders. Our unique form of ownership places employee owners on every Project, thereby assuring our Clients the highest level of Success.


The PKF approach is founded upon strong, collaborative efforts that ensure the sharing of ideas and the involvement of all stakeholders. As thought leaders in the industry, our team creates solutions that get the job done on time and done correctly.


Our passion and drive to be the best is evidenced by the superior quality of our workmanship. Our attention to detail makes the most difficult tasks appear simple. We strive in all matters to achieve a standard that exceeds those in the industry, and we will not accept anything less.
