A.H. Beck installs 74 shafts behind an existing damaged historical wall of a significant cultural landmark in Old San Juan, Puerto Rico
The job consisted of drilling 74 drill shafts behind an existing damaged historical wall. The fortifications of Old San Juan represent a highly significant cultural and historic landmark to Puerto Rico. The National Park Service is charged with the preservation and maintenance of this historical landmark. The NPS issued a permit to PR DTOP to reinforce the damaged wall, which would later be reconstructed in the same manner it was originally constructed more than 300 years ago.
A. H. Beck designed and installed 74 – 36” diameter shafts close to 80’ deep soldier piers to support and protect the existing historical wall. A. H. Beck also had to rebuild the existing sidewalk and street above the wall after the soldier pier construction was complete. Due to the historical nature of this repair several agencies were involved: PR Historic Conservation Office, NPS, PR DTOP, Autoridad de Carreteras, and the San Juan Mayors Office, along with personnel from the Governor’s Office.
