New Grinder Pit for Sabert Corporation, Sayreville, New
Jersey. Sabert expanded production of stamped plastic food grade bowls and
similar products required a new rectangular pit (14' X 22') set eight foot
below finished floor and due to space constraints, had to be situated near the
intersection of two building additions. As a result, the pit potentially
undermined two column footings and two masonry walls. To complicate matters,
the excavation, shoring and concrete placement work had to be conducted without
compromising a clean facility. Did we mention the high water table?
We developed an economical and constructible solution while protecting
both the existing foundations and the workers below grade. We specified a
step-by-step process utilizing 3X6 sheeting, two layers of steel compression
rings to hold the sheeting in position and a multi-stage concrete pouring
schedule. Keeping the nearby area clean was accomplished by the contractor by
erecting plastic sheeting light gage metal walls and power venting the space
directly outside while maintaining negative air pressure. To everyone's
delight, the project was completed on time and on budget.
