Between 2013 and 2016 Existing Structures Engineering (ESE) provided Cathodic Protection Specialist and Testing services on fifteen (15) different FDOT Bridge rehabilitation projects across the state of Florida. Testing services provided included reinforcing steel continuity on bridge bent cap repair; adhesion, continuity to steel reinforcing and thickness measurements for zinc metalizing of steel and concrete surfaces; installation of structural and non-structural galvanic pile jackets; and commissioning of ICCP (Impressed Current Cathodic Protection) systems on bridge support structures.

Although the coastal environment is known to be very corrosive, it should come as no surprise that “fresh water” structures can also need significant maintenance to stay serviceable. Because fireworks fallout and fertilizers, some of the theme park water we have tested is nearly as corrosive as seawater. But these flood control structures that we evaluated the service bridges on are as “out in the middle of nowhere” as you can get. But natural tannins, fertilizer and age still take their toll. These flood control structures are being refurbished and we confirmed that the service bridges are structurally suitable for light construction traffic (but never crane load a hatch or trench cover!).
ESE was commissioned to design two roof-mounted racks to support antennas weighing approximately 4000 Pounds each. The roof-mounted racks were to be attached to the roof framing atop a building located on Cape Canaveral’s Air Force Station. ESE had to first confirm the as-built drawings of the roof plan. Next, the conceptual design was roughly detailed and submitted. Once this preliminary design was approved by the client, the detailed design was modeled using STAAD.Pro to perform a structural analysis. An AISC code check was executed on all steel elements. A stress analysis indicated that all stresses were within allowable and the structure passed on code and statics checks. ESE provided ongoing support during fabrication and installation of the antenna racks.
Existing Structures Engineering, Inc. provides Specialized Services in places all over the World,
most recently deploying to Lumut, Malaysia. Malaysia is a distance of about 10,450 miles away,
(4° 14′ 0″ North, 100° 38′ 0″ East) and ESE’s experts were commissioned to evaluate a marine mechanical lift dock for dry docking large ships, including warships. The structure is built of large steel girders and beams with a timber and crane rail deck and after 30 years had finally corroded beyond the point of repair.
Oldest Structure Yet!
ESE was brought in specifically to evaluate the effect of corrosion on the IMT Syncrolift located in Lemont, IL. The mechanical lift dock was commissioned in 1969 and has been in use ever since.
During the ultrasound inspection of the scantlings, the Engineers were surprised to find riveted main transverse beams. Riveted construction has been out of use since the mid 1940’s.
Ocean Royale started as a typical balcony restoration project. However, once the edges of the balconies were opened, the severity of the Post Tension (PT) cable damage was uncovered.
ESE determined that it was more cost effective to replace every PT anchor in the east edges of all balconies. This meant taking twelve inches of concrete off of each edge and creating access holes every three feet at about three feet in from the edge to feed new PT cables ends through the new concrete edge.
Ocean Sands North is located in Indialantic, FL.
Due to the harsh coastal environment and previous improper repairs, the balconies were severely damaged beyond economical repair.
Falling edge debris caused pool closure prior to restoration.
Seaport Canaveral Tank Farm, located on more than 30 acres in Port Canaveral, FL, was the largest construction project in Brevard County for the few years that it was under construction. It was, at the time, also the largest single investment in Port history.
The Seaport Canaveral Tank Farm project consisted of the installation of 24 above ground petroleum storage tanks including facilities to support the storage and transfer of petroleum on and off site. This project was new construction and Existing Structures Engineering, Inc. (ESE) was involved from the day construction commenced. ESE provided construction management and oversight of the onsite construction and placement of over 120 miles of prestressed concrete pilings, ranging from 25 ft in length to 50 feet in length.
ESE was hired by the golf course community to determine the condition of multiple underground steel culverts which connected various lakes around the course.
Some culverts ran under roadways which caused a need to ensure long term safety of the residents.
