The right foundation.
Like a good education, a school should be built on the right foundation—and by an expert infrastructure team capable of addressing its unique challenges. Engaged as the Design-Assist contractor, Impetus was afforded the opportunity to build Kenner Discovery Health Sciences Academy’s campus. As the first new public school construction on the Eastbank of Jefferson Parish since the 1980s, the school would have a permanent footprint of 125,000 square feet to meet the school’s growing demand for space and diverse educational offerings. Impetus’ Infrastructure Team was tasked with prepping the site for its foundation through drainage, reshaping, and base, as well as installing utilities durable enough to support the school’s population. However, building in Kenner is no small feat. Whether it was digging up holes for piles or installing piping, the high water table made for an unrelenting challenge. Fortunately, we’re not ones to shy away from obstacles.
Cost-effective and innovative.
To build in the Greater New Orleans region is to understand the significant part water plays in creating chaos for any project. As a former swamp, the area was drained ten years prior and filled with ten feet of sand. When the Infrastructure Team began work at the project’s kick-off, water quickly filled any holes or trenches that were dug. Our team worked with engineering firm Linfield Hunter & Junius to formulate an effective solution that could adhere to the building’s plan and the client’s budget. A retention pond with 220,000 cubic feet of storage capacity was the ideal response for managing the issue. After getting the site to elevation, the team dug drainage trenches from the building’s footprint to the retention pond. This strategy moved the water away from the building’s crucial foundation components, such as piles, footings, and pile caps. However, the terrain was also an issue for the pond itself. The sand embankments would continuously erode. Working with geotechnical and civil engineers, we created a cost-effective and innovative solution. Visqueen lining was layered onto the pond slopes along with #57 stone. The weight of the stone held the sand and soil in place, allowing it to flow through the top of the stone without eroding the ground.
