FRENCH BRANCH PROJECT

The Louisiana Department of Transportation and Development (DOTD) contracted Barriere Construction Company, LLC to complete a $40 million road rehabilitation project to resurface almost 10 miles of interstate highway in eastern St. Tammany Parish, replacing worn faulted concrete pavement on Interstate 10 from the West Pearl River Bridge to the French Branch Bridge. This section of interstate had not received many substantive improvements since the 1960’s and presented complicated issues resulting from poor subbase and water intrusion.

The project challenged Barriere and DOTD to construct a safer and more efficient highway by eliminating excessive roadway irregularities and wear and tear on vehicles. Barriere crews worked to replace the existing poorly conditioned subbase as well as reconstruct five corresponding off-ramps with the highest level of safety and without a single lane closure infraction.

In winning the project Barriere proposed a 360-day timeline, which was 315 days faster than other competitors’ proposals. Although additional work was added to the contracted scope, Barriere’s use of innovative tools such as drone surveying and intensive scheduling enabled Barriere to complete the project in just 307 days...71 DAYS AHEAD OF SCHEDULE.

Over and above the initial scope of work, DOTD asked for additional guardrail where existing structures did not meet required specifications, due to inconsistent road leveling. Milling and asphalt leveling were also included to fix the substandard slopes on the project as well as minor adjustment to ITS boxes and the relocation of multiple signs. The client added $745,000 of work to the project, but the savings generated through Value Engineering and expert innovation more than covered the additional cost.

I would like to share my gratitude toward you and your entire team at Barriere for all of the hard work and long hours required to successfully complete this $40 Million project ahead of schedule and under budget. In addition, I would like to compliment you and the others on the project management team for a job well done. Barriere Construction demonstrated their dedication to maintaining a trustworthy and committed relationship with the Department and Volkert (CE&I) to make this a successful partnering experience. This project is something to be proud of and I’m glad to be a part of it."
