Installing pre-cast concrete piles near MMLS The limited access H-piles had to be installed in 11 sections at each
the additional scope, Cajun Industries’ Deep Foundations Business
Unit teamed up with Cajun’s Baton Rouge Civil Business Unit and
Cajun Engineering Solutions to provide a turnkey solution to IHI.
Our scope included engineering of the temporary retaining sheet
pile structures, installation of precast concrete piles, excavation of
in-situ soil material, installation of structural concrete basins and
backfill around the concrete basins.
Cajun was successfully awarded the lump sum change order
by IHI on May 10, 2017. Cajun had six weeks to finalize/submit
engineered shoring drawings for review and approval, procure

the engineering of the temporary retaining structures (TRS) on
the site. The TRS’s were composed of sheet pile wall systems that
enabled Cajun to successfully excavate and install concrete basins
without open cutting and taking up additional space on site. The
TRS structures were important, as the island did not have much
land to issue for our construction operation, as every square foot
was at a premium.
After the TRS systems were approved by IHI, Cajun submitted
the designed sheet pile systems to its Westport fabrication facility
to begin processing the required sheet pile materials for the project.
The fabrication operation handled a total of 1.1 million pounds
of sheet piles in 12 days, to ensure that the sheet pile crew could
