DOS BOCAS REFINERY
MORRIS-SHEA PROJECT COMPONENTS CFA PILE
437 32 INCH DIAMETER PILES
193 1 METER DIAMETER PILES
Morris-Shea, a leading deep foundation contractor, constructed a CFA deep foundation installation for pipe racks at the new Dos Bocas Refinery in Paraíso, Mexico. The Petroleos Mexicanos (PEMEX) facility will be the largest oil products refinery in the country. Morris-Shea was awarded the Site 2 pile contract after the successful installation of deep foundations at the refinery’s Site 1 location. CFA pile satisfies all foundation load requirements for pipe running up to a half mile in distance between storage tanks and/or processing plants. Morris-Shea’s Mexico team performed quality installations in job sites congested with the ongoing activities, equipment and spoils of current and previous contractors.
CFA DEEP FOUNDATION INSTALLATION
The Dos Bocas Refinery Project required the installation of 437 32 inch diameter and 193 1 meter diameter Continuous Flight Auger (CFA) piles drilled to a depth of 100 feet. Morris-Shea’s Mexico team utilized 2 Fundex 3500 drill rigs with Onboard Automated Monitoring Systems to assure quality pile installation in varying subsurface soil and rock environments. The drilling often necessitated working in unstable soft and dangerous surface soil conditions. The pipe racks ranged in distance up to one half mile and required the movement of the drill rigs. Full length steel cages were fabricated at the job site and installed as reinforcement in the specialty cement mix.
CFA PILE REDUCED PRODUCTION TIME
The installation of CFA pile, rather than typical augercast piles, reduced production time and improved load capacity. Morris-Shea was able to install as many as sixteen 1 meter diameter CFA pile to a depth of 100 feet in a single day at the Dos Bocas Refinery.
