Infrastructure Engineers provided project management and design services for the roadway extension of Thacker Avenue from Donegan Avenue to Carroll Street, a distance of approximately 2000-ft. The scope of the project included design survey, right-of-way mapping, geotechnical investigation, environmental services, roadway and drainage design, signing and pavement marking, signalization, permitting, and post design services. The ultimate typical section is a four lane, divided urban section. Infrastructure Engineers participated in a public involvement program for this project. City of St. Cloud, Florida
Infrastructure Engineers provided project management and design services for the two-lane roadway extension of Budinger Avenue from the new St. Cloud Elementary School to 17th Street. A third lane will be provided adjacent to the school site. The project included minor wetland impacts along the easterly right of way as well as parcel takes in order to provide sufficient right-of-way and water management ponds. Infrastructure Engineers participated in a public involvement program for this project. Florida Department of Transportation, District 2
State Road 20 is part of Florida's Strategic Intermodal System (SIS) and the Florida Intrastate Highway System (FIHS) that runs from US 98 in Gilchrist County east to I-95 in St. Johns County. This project involves the milling and resurfacing of the portion of road in Alachua County from State Road 24 (Waldo Road) to SE 14th Street. The existing road is a six-lane divided section with curb and gutter. There are two 12-ft. through lanes and one 10-ft. turn lane on each side of the median. Florida’s turnpike enterprise – Northern system Infrastructure Engineer has been selected for two consecutive cycles to perform inspection services on the northern system of Florida's Turnpike. The project includes structures in Hernando, Hillsborough, Orange, Osceola, Pasco, Polk, Seminole, and St. Lucie counties. U.S. Department of the Interior, Bureau of Indian Affairs

Infrastructure Engineers has been selected for two consecutive cycles to perform bridge inspections and prepare an inventory of Indian-owned bridges throughout the United States. Inspections were both NBIS and underwater and included construction materials of various types. Equipment and personnel are transported nationwide to conduct the inspections, and engineering reports were prepared using the 
Infrastructure Engineers has been selected for two consecutive IDIQ contracts to perform routine and underwater inspections of waterfront structures and bridges located throughout the United States; Guantanamo Bay, Cuba; Exmouth, Australia; and Okinawa, Japan. Additional responsibilities include engineering calculations for structural analysis (with or without previous design calculations), documentation of findings, and recommendations for follow-up actions, including cost estimates and rehabilitation design of waterfront facilities.
Infrastructure Engineers was selected by the U.S. Army Corps of Engineers to provide continuing diving inspection services at various culverts, canals, levees, and spillways throughout Florida. The project includes construction services. Typical underwater projects have included underwater drilling at a pump station, inspection of spillway sheet piling and structural integrity, overall lock inspection, and the underwater inspection and cleaning of a spillway structure.
Infrastructure Engineers was selected to perform five cycles of inspections on all structural signs throughout District Five of the Florida Department of Transportation. A detailed inspection report was prepared for each structure. The project included traffic control for interstate highways. Non-destructive testing of welds was required to evaluate conditions at many sites. During one cycle, the firm did a structural analysis 
Infrastructure Engineers has been selected by the Mississippi Department of Transportation to perform two cycles of underwater bridge inspections throughout the state. Two bridges crossed the Mississippi River, while the majority of the crossings were over smaller rivers, creeks, and other water bodies. Each inspection required an in-depth engineering report with scaled CAD drawings illustrating defects.
Infrastructure Engineers was selected to conduct underwater inspection of local government-owned structures for three consecutive cycles. The scope of work involved local government structures throughout the state. A detailed report was prepared for each bridge, to include underwater photographs of deficiencies. 
Infrastructure Engineers was retained by the Arkansas State Highway and Transportation Department (AHTD) to conduct underwater inspections of state-owned bridges in 1998, 2001, 2003, and most recently, 2006. Several bridges were over the Arkansas River Navigational Channel. Four bridges crossed deep water lakes and entailed dives up to 120-feet deep and the availability of a recompression chamber. Typical water depth was 35-feet with generally poor diving conditions around moderate timber debris in black water.
Infrastructure Engineers was retained by A.G. Lichtenstein to provide structural and underwater inspection services on their bridge inspection contract with the Florida Department of Transportation Turnpike Enterprise. Each inspection was based on the NBIS and followed all OSHA and FDOT safety guidelines.
Lichtenstein Consulting Engineers retained Infrastructure Engineers to perform underwater inspections of approximately 245 bridges as part of their districtwide bridge inspection project. The inspections included the substructures, embankment bulkheads and fender systems. Infrastructure Engineers prepared an engineering report with underwater photographs documenting defects. Inspections were based on the NBIS and documented in accordance with Florida Department of Transportation and FHWA guidelines.
Infrastructure Engineers was selected for two consecutive two-year on-call underwater inspection services contracts for bridges and ferry terminals throughout the state. Typical diving conditions included swift currents and tidal flow conditions. Detailed engineering reports with channel contours were required for each structure. 
Infrastructure Engineers was retained by the Wyoming Department of Transportation to perform underwater inspections of 70 state-owned and local government bridges throughout the state. Structures included timber, steel, and concrete. A detailed engineering report was prepared for each structure which included color photographs of deficiencies and CAD drawings. 
Infrastructure Engineers was selected to perform underwater inspection of 74 bridges throughout Colorado. The inspections included two bridges crossing the Blue Mesa Reservoir in depths in excess of 200 feet (adjusted for altitude at an elevation of 7500 feet). The inspections at Blue Mesa were conducted using a helium and oxygen breathing gas mixture, and a decompression chamber was required for surface decompression on oxygen type decompression. Hot water suits were used for the dives due to extended decompression times and cold water. 
Infrastructure Engineers was selected by the Virginia Department of Transportation to perform underwater inspections of 33 complex bridges throughout the state. Underwater assessment included, but was not limited to, underwater inspection, engineering analysis of existing conditions, engineering calculations, recommendations of follow-up action, and documentation of findings. Each inspection required an in-depth engineering report with CAD drawings illustrating defects. 
Infrastructure Engineers provided underwater inspection services for 36 bridges in Oklahoma as a subconsultant to Cobb Engineering. Two of the bridges cross Lake Texoma and include 116 piers with an average depth of 70 feet. The remaining bridges crossed various streams and rivers throughout the southeastern part of the state. 
Infrastructure Engineers was retained by Iowa Department of Transportation to perform underwater inspection of 59 bridges throughout the state. Bridges included timber, steel, and concrete construction crossing streams and rivers with swift currents, limited access and zero visibility. Each inspection required an in-depth engineering report with soundings and CAD drawings.
