Locally owned since 1972, we aim to be a preferred provider of civil engineering and surveying services for municipal, commercial, and residential clients.
Our mission is to deliver innovative, high-quality civil engineering and surveying solutions on time and with exceptional value, helping our clients and communities build a stronger, more sustainable future.
Drawing on extensive experience serving municipalities throughout the Greater Lehigh Valley and Pocono regions, our team provides responsive, practical expertise tailored to each community’s needs. Our capabilities include, but not limited to, inspections; roadway, bridge, storm sewer, sanitary sewer, and water system design; sewage enforcement officer services; postal address systems; technical revisions to subdivision and zoning ordinances; traffic studies; roadway improvement programs; wetland delineations and Phase 1 Environmental Site Assessments; and sewer system infiltration and inflow removal programs.
Frank G. Waldraff founded Waldraff Associates in 1972 after working as an engineer for a large local manufacturing company. He rejected its hierarchical, “top-down” management style-what he described as “people parading around wearing stripes and expecting everybody to salute them”-and set out to build a very different kind of engineering firm.
Frank chose to empower employees and treat everyone as equals. That approach created a collaborative team whose members supported one another and worked closely with clients to exceed expectations through efficient, responsive service.
Waldraff Associates became Keystone Consulting Engineers (KCE) in 1984. Although Frank retired in June 2002, his leadership philosophy continues to shape KCE’s highly motivated, people-first culture, client-service focus, and strong work ethic. The firm’s low employee turnover and long-standing client relationships reflect that enduring legacy. In 2007, KCE received the Greater Lehigh Valley Excellence in Business Award, further recognizing the strength of the mentoring and management philosophy Frank established.
William Erdman became president in 2002 after Frank’s retirement, ushering in a new era while upholding the firm’s core values and commitment to client service. Under his leadership, KCE expanded in the Pocono region with a new office in Kresgeville.
Albert Kortze was nominated as its new president in 2008, advancing KCE’s growth and service while relocating and expanding its Allentown and Bethlehem offices during his tenure.
Upon Albert’s retirement, Eric Snyder became president in 2023 continuing to present day, carrying forward KCE’s tradition of thoughtful leadership and preparing the firm for continued success. In 2026, KCE strengthened its Pocono-area presence by relocating to its Brodheadsville office.
Keystone Consulting Engineers, Inc. delegates total authority for each client project to a specific KCE employee or team. This philosophy provides a more direct link between the client and the project manager and eliminates the second and third-hand layers typically associated with a “top-down” style of management.
KCE clients can consistently rely on the same qualified individuals year after year. In turn, our personnel develop long-term relationships and a great synergy with clients, thus enabling the project manager to better anticipate and satisfy their needs.
As a locally owned, multi-discipline civil engineering firm that provides a full spectrum of engineering services in a wide range of fields (precision boundary and topographic surveying, municipal engineering, subdivision and land development, highway and traffic engineering, environmental engineering, and construction inspection services), KCE. aspires to deliver through our dedicated and empowered employees, reliable and cost-effective service to our clients.
Municipal engineering is the “foundation” of KCE. Consequently, the firm does not take on new clients with private engineering projects located within any of the municipalities where KCE is the municipal engineer, ensuring complete objectivity.
For private land developers, our vast municipal consulting experience helps their plans obtain the required municipal approval. Because KCE performs both municipal representation and private land development work, our engineers fully understand both sides of the approval process. For municipalities and developers alike, KCE’s knowledge, experience, and commitment allow us to deliver unmatched project quality, timeliness, and cost-efficiency.
Keystone has been in practice of civil engineering since June 1972 and has provided civil and consulting engineering services to numerous municipalities, authorities, and land developers throughout the greater Lehigh Valley and Pocono Regions areas. KCE is a wholly-owned Pennsylvania corporation with nineteen stockholders. Founder Frank Waldraff, wishing to provide younger, key employees with the opportunity to participate in the company’s growth and leadership, established an orderly and planned management transition process. The Company is founded on a unique management approach which delegates total authority for each client or project to specific, qualified individuals. This provides a more direct link between the client and our firm and eliminates the administrative overhead associated with a “top-down” management style. This management philosophy provides cost-effective engineering services.
At Keystone, the client can consistently depend on the same qualified individual. In turn, our personnel can become increasingly familiar with the client and its needs. Depending on the situation, the individual engineer will consult with other senior staff personnel who have a broad range of both educational and practical experience in specific areas of engineering. In addition, the company promotes continued growth through seminars, education, and on-the-job training. The result of this management style and educational program is evident by the low employee turnover and corresponding high average years of service per employee.
The staff presently consists of approximately 70 engineers, surveyors, and technical personnel, including fourteen (14) Registered Professional Engineers, two(2) Registered Professional Land Surveyors, one (1) Registered Geologist and one (1) Registered Landscape Architect. The principal office is located at 2870 Emrick Boulevard in Bethlehem, Pennsylvania with branch offices at 5012 Medical Center Circle, Suite 1 in Allentown, Pennsylvania and 863 Interchange Road, P.O. Box 639, Kresgeville, Pennsylvania.
