Projects & Awards

Barriere’s unprecedented level of quality and craftsmanship come down to three main differentiators: coordination, logistics, and timeliness. Our company has always taken great pride in building, developing, and sustaining long-term partnerships in all of our jobs which has led to a quality of innovation that goes unmatched in Southeast Louisiana, often times resulting in value engineering opportunities for our clients.

Over the years, Barriere’s Heavy Civil, Asphalt, and Industrial Group teams have been honored and privileged to have worked with so many pivotal partners under difficult conditions to overcome obstacles and successfully complete projects on time and under budget. To do so requires dedicated and experienced crews, creativity, and a commitment to innovation, safety, and quality with partners at all levels of a project.

Our employees and project teams not only want to raise the performance bar; they aim to set the industry standard in improving the infrastructure of our region. These values have helped strengthen respect and integrity between owner, contractor, project engineer, and all subcontractors involved in these projects as we strive to improve the infrastructure of our region.

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.

From a safety perspective, one of the biggest and most important challenges involved the nature of the project itself: the convergence of three major heavily trafficked interstates (I-10, I-59 and I-12) and a volume of approximately 100,000 automobiles and trucks per day.

The French Branch 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 the adjusted timeline).

Over and above the initial scope of work, DOTD asked Barriere to add additional guardrail in places where the 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. Barriere completed other minor change orders including the adjustment of ITS boxes and the relocation of multiple signs. In total the client added $745,000 of work to the project, but the savings Barriere generated through Value Engineering and expert innovation more than covered the additional cost.

Barriere was contracted by the City of New Orleans for the St. Bernard Avenue reconstruction project, a total reconstruction of underground utilities and roadway on St. Bernard Ave. This section of roadway had historically been referred to as one of the worst avenues in the city – it is considered the birthplace of the Fix-My-Streets movement.

The general scope of work for this project included removing and replacing sidewalks, replacing the water and sewer lines, replacing the drainage lines and repaving the roadway in concrete between Filmore Ave. and Robert E. Lee Blvd., and Spanish Fort Shell Rd. between Soldiers and Madrid streets.

At the start of the project, the existing overlaid concrete road was in a horrible state of deterioration, and sections of roadway were barely passable by car because of large potholes. Due to existing conditions Barriere and the owner decided it was best to repair potholes and install a thin overlay on the existing roadway so that two-way traffic could safely be maintained. The sidewalk was in such poor shape that it served no purpose to pedestrians. Furthermore, the existing water distribution system had multiple leaks, and the storm drainage system was also dilapidated with missing structure covers, and blocked or collapsed pipes.

Barriere partnered with 11 different DBE subcontractors and suppliers in compliance with the required 35% DBE component. Subcontractor scope included trucking, sidewalks, driveways, concrete supply, sand supply, brick work, temporary signs and barricades, and permanent striping. The City of New Orleans, in tandem with Barriere, remained in constant communication with neighborhood associations to update the public on the project’s progress. Monthly internal project planning and schedule updates and biweekly progress meetings ensured that all parties were engaged and committed to meeting milestone dates.

It was Barriere’s detailed planning and allotment of resources that allowed Barriere to prevent any major lulls in the work. Innovation played a huge role in our success as we utilized state of the art GPS technology on bulldozers, graders, and, for the first time, excavators. Barriere overcame inclement weather early in the project, which delayed the installation of the river bound roadway paving, to successfully complete the project in December 2016.

In September 2015, Occidental Chemical Corporation contracted Barriere Construction, LLC to update the existing 50-year-old tank containment system at its Geismar, LA plant. The project challenged Barriere to construct a substantial containment system with no safety incidents, no budget overages, and high customer satisfaction. As part of the project scope, Barriere was required to maintain the existing out-of-date system while building a new tank containment system that would meet the current EPA standards. The job required the rerouting of storm water to a testing facility before draining since it was an active plant site, and severe weather and flooding presented additional complexities for the Barriere team.

Our team of innovative experts immediately evaluated the Occidental Chemical project site and submitted a value engineering proposal which was accepted by the owner. The agreement to construct earthen berm in lieu of columns and posts, as contracted, helped offset extreme weather delays and reduce the amount of excavated material that would need to be hauled to and from a restricted site layout. To avoid delays and overcome project obstacles, the Barriere Project Management Team recognized that there would be a need to accelerate a Supervisory commitment to safety and efficiency. Barriere’s foresight led to the creation of a supervisor leadership training program model for employees on the work site. The decision to require on-the-job employee training, a self-imposed Barriere requirement, extended beyond the contracted scope of the project to increase on-site productivity, improve communication and provide professional growth opportunities for individuals.

Stacked against the odds of Louisiana flooding and rain and unforeseen obstacles, both known and unknown, Barriere completed the Primary Tank Containment System on December 31, 2015 (5 days ahead of schedule).
