ST. GEORGE ISLAND BRIDGE

Project Description

Client: Florida Department of Transportation

Location: St. George Island, FL

Date of Completion: Feb 2004

The 4.5 mile bridge spans the Appalachiocola Bay from Eastpoint, Florida to St. George Island, a barrier island off the coast of Florida. The design build proposal allowed Boh Bros. to have complete control over the project and to guarantee a quick completion time. The bridge was constructed 1500 ft. from the old bridge and built using specially manufactured concrete cylinder piles and pre-cast concrete caps. The bridge also features prestressed concrete bulb tee girder approach spans and five post-tension spans over a 250 ft. channel.

As part of the contract, Boh Bros. demolished and removed a large portion of the old bridge while leaving 3250 ft. at the end of each span to serve as fishing piers. Boh Bros. gave the Florida Department of Transportation an unprecedented 10 year abutment to abutment warranty.

LOCAP EXCAVATION PROJECT

Project Description

Client: LOCAP
Location: St. James, LA
Date of Completion: July 2014

The Challenge

Boh Bros. recently deployed its proprietary Hydro-Jet Vacuum Excavation System, U.S. Patent No. 8,858,124, to support a major modification project at the LOCAP crude oil pipeline facility in St. James, LA. The owner specifically requested Boh’s patented system because the project required excavation in a highly congested area filled with more than 60 energized cables and conduits, and it had to be done without disrupting LOCAP’s operations. Using the system made it possible for the Boh team to successfully excavate more than 2,000 cubic yards of material in fewer than 50 days with no facility shut downs for nearly 3,500 man-hours of work. Tim Thibodaux, LOCAP’s supervisor, commented, “This is the best technology I’ve seen utilized in a setting such as ours. Nothing compares to it when it comes to safety, protecting the environment, and damage prevention of our pipeline.” Boh’s delicate, successful excavation around so many obstacles was an integral part of the success of the overall manifold modification project.
