After four demanding years of permitting,
In 2015, construction will primarily consist of site preparation and soil stabilization activities that include removing, augmenting and hauling tremendous amounts of soil. Between the two sites, it is anticipated that over of 1.1 million cubic yards of dirt will be shaped and prepared to support the construction equipment necessary for building foundations and erecting production facilities.
On Quintana Island site, most of the dirt work is soil stabilization using an "in-situ" cement process.
This method employs up to 16 track hoes working across the site. At each assigned plot, a track hoe places a modified sea container into which 25 tons of cement is pumped. The hoe then spreads the cement across its assigned area and starts to mix it with soil.
Work is also underway along the Intracoastal Waterway to construct a new aggregate dock to support deliveries of materials for the concrete batch plant, liquefaction plant construction materials and major equipment such as compressors, heat exchangers, electric motors and fan coolers.

Pretreatment Site Soil Stabilization
At the pretreatment site, soil preparation involves only a small amount of cement stabilization. Work here consists primarily of cutting and filling with virgin soil, and mixing it with lime to dry material that has become waterlogged by persistent spring rains. The entire perimeter of the site is also lined with silt fencing to prevent any adverse impact of water runoff on the existing wetlands in the area.
