PROJECT OVERVIEW

Site clearing, support of excavation using slide rail shoring system, excavate and backfill MGP impacted soils approximately 15 feet below existing grade, truck and dispose of impacted soils at an approved National Grid thermal desorption facility.

WHAT MADE THIS JOB COMPLEX

The most challenging issue here was the fact that Posillico was excavating 15 feet below grade adjacent to an electrical substation. There was limited room for equipment and personnel which added to the difficulty.

HOW POSILLICO SOLVED IT

Posillico solved this issue by designing a shoring system to compensate for the small work areas so the clean fill was not contaminated with dirty excavation.
