McCrossin Foundations was contracted to install the caissons at the Dale and Frances Hughes Cancer Center at Pocono Medical Center in East Stroudsburg, Pennsylvania. The project consisted of 62 foundation caissons having diameters of 30 and 48 inches with lengths up to 70 feet. Our crews encountered a limestone boulder field within the glacial sand overburden that required significant efforts to excavate. Temporary casings were telescoped through the overburden and weathered rock stratums to the limestone bedrock. The caissons had sockets into the bedrock between three and six feet. The project was completed between December, 2010 and February, 2011. Multiple drill crews were used, working significant overtime to complete the project within the schedule requested.
We furnished and installed all reinforcing steel, and accommodated considerable changes in caisson length due to variable site conditions from planned lengths. The caissons were de-watered and concrete was placed by free falling the concrete no more than 25-feet per the specifications.
Our management team provided cost-saving suggestions to the owner, including the elimination of down-the-hole inspection/cleaning (done by reducing the caisson lengths and by accounting for skin friction through the weathered bedrock).
Micropiles were drilled for pier foundations adjacent to the main entrance to the hospital. Drilling was difficult due to the existing footers that were drilled through, and the time constraints of the entrance closure. Protection of the existing building was of paramount importance during the installation process.
