Alpha Corporation has been selected to provide construction management services for the National Park Service for the rehabilitation/repair of the historic Independence Hall Tower, which once housed the Liberty Bell in Philadelphia. This project will arrest deterioration of the Tower due to water damage and replace and refurbish selected deteriorated elements including roofing, wood siding, decorative wood elements, balusters, and the copper urns on the tower. A new lightning protection system will also be installed.

The tower, one of the earliest examples of Colonial Revival architecture, was designed by William Strickland and built in 1828, replacing the original tower, which dated from 1750. This project will be funded by the “American Recovery and Reinvestment Act of 2009”. In addition to full-time on-site CM, Alpha Corporation will provide special inspections, project controls, and contract administration during the construction,which will take approximately 18 months and will take place while Independence Hall is open to the public, requiring stringent safety procedures.

This project will add to Alpha’s track record of engineering and construction management on Historic National Monuments and Memorials such as the Washington Monument, Lincoln Memorial, Jefferson Memorial, Jamestown Island, Ellis Island, Pentagon Memorial, etc. The Independence Hall Tower Project also represents one of twenty recent ARRA-funded NPS projects awarded to Alpha for CM services, totaling over $100 million in construction value.
