Phoenix Project #1905
This project called for the installation of four (4) drilled micropiles (“DMPs”) to support a new jetway foundation at Logan Airport in Boston, MA.
The project’s pile design utilized drill casing as the core reinforcement, requiring Phoenix to abandon a sacrificial roller bit at the end of each pile. Top of rock was substantially deeper than assumed, resulting in pile depths of 170 feet below existing ground surface.
The work was performed “airside”, within close proximity to Logan’s International Terminal E building – and just a stone’s throw from several large aircraft. In this highly sensitive environment, safe and effective materials handling and spoils management were paramount.
Phoenix successfully completed this project in the Spring of 2019. Shortly thereafter, Suffolk Construction Company and Massport awarded Phoenix with the follow-up work package, consisting of 178 DMPs overall – most located airside. Of particular note, a handful of these piles are located inside Terminal E’s Checked Baggage inspection System (CBIS) facility, which must remain active throughout the construction process.
