East Office

Since the founding of Keystone Consulting Engineers, Inc. (KCE) in 1972 (as Waldraff Associates), there has been a focus on efficient, personal, and cost-effective service for our clients. Built upon a management philosophy that empowers its employees and results in historically low employee turnover, KCE allows the personal client/project engineer relationship to prosper. The benefits of such relationships are evidenced by KCE’s many long-time and repeat clients.
Originally the sole KCE office, the East Office now provides a customer service base of operations for such clients as Hanover Township (Lehigh County), Upper and Lower Nazareth Townships, Bethworks, Keystone Cement, and Moravian College.
The East Office is staffed by 17 individuals with expertise in a multitude of engineering disciplines: municipal, environmental, highway & traffic, soil sciences, surveying, subdivision and land development, construction inspection, and GIS.

Unique engineering disciplines/applications for KCE East Office/Bethlehem

Moravian College Main Street Improvements– A block-long landscaped island with enhanced crosswalks and corner curbline extensions to create a more pedestrian-friendly situation within a major thoroughfare at the campus’s entrance. In addition to slowing vehicular traffic and providing a mid-crossing refuge for pedestrians, these improvements frame an attractive gateway into Moravian College.

Keystone Cement Company – The $200 million plant modernization project’s most visible improvement is a 320-foot tall twin concrete tower, within which limestone will be heated to 1650 degrees Fahrenheit before it goes into a new kiln that converts it into cement. The plant modernization also includes an entirely new mining area and crusher that utilizes a 1 one-mile long air gravity conveyor and silo feed chutes to carry the raw material to the plant for processing.

Frost Hollow Swale Reconstruction – KCE designed and fully coordinated the reconstruction and armored lining of a 3,300 foot long, 20 foot wide and 5 foot deep drainage swale running through a medium density residential development consisting of approximately 75 homes. The existing swale had filled in over a period of approximately 30 years to the point which caused adjacent homes to be flooded on a regular basis.

Cedar Creek Farm – KCE served as the principal civil engineer on this planned residential development project that consisted of 149 single-family homes, 90 townhomes, and 60 condominium units. Road, waterline, sanitary sewer, stormwater management, and lot grading design were all performed by KCE, and KCE then guided the project through the municipal approval / governmental permitting processes.
