Founded by William J. Castle in 1983, we are a structural/civil
engineering company. We provide structural designs, inspection services,
testing, and more to both government agencies and private contractors
and companies.
For over 25 years, W. J. Castle has been known for its marine engineering
expertise. Our team includes Structural and Civil Engineers who offer
complete structural designs for building, replacing, or repairing
bridges, piers, docks, underwater cables and more. We also employ
Engineer-Divers who are proficient at underwater diagnostics and
reporting, with the ability to develop repair designs as needed.
No matter what the project, we use the most state-of-the-art technology
available to diagnose the situation. We then convert our engineering
insight into practical design solutions that can be implemented quickly
and efficiently, and are guaranteed to work well for years to come.

Hydrographic / Fathometric Surveys
W.J. Castle has performed Hydrographic / Fathometric Surveys on numerous
bridges, including single and multi-span structures, such as:
Verrazano-Narrows Bridge (NY)
Burlington Bristol Bridge (NJ - PA)
Newburgh-Beacon Bridge (I-78 in NY)
Walt Whitman Bridge (NJ - PA)
Betsy Ross Bridge (NJ - PA)
We have the ability and equipment necessary to provide state-of-the-art
surveys and reports. Our latest technology includes a multi-beam
transducer unit as well as a single beam transducer unit with digital
and/or graphic printout information.
Side Scan Sonar
Using the JW Fishers Side Scan Sonar-100K/600K, we are able to view large search areas quickly and produce high-resolution images of the river bottom up to 40 meters from the sonar head. This model has both low and high frequency transducers in one towfish. The towfish is rated for 500 feet depth and is equipped with 150 feet of cable. The data that is collected is then sent to a laptop computer where it can display a real time color image of the river or ocean bottom.
