The Challenge
Preserving Essential Port Infrastructure
Philadelphia's working waterfront depends on reliable infrastructure to support maritime operations and the movement of goods. Maintaining existing wharf structures is essential to preserving the functionality of these facilities and supporting the region's maritime economy.
The Pier 82S Rehabilitation Project involves repairing approximately 135 linear feet of existing wharf, alongside evaluations of adjacent areas to inform long-term maintenance and operational planning.
Working with an existing waterfront structure introduces several engineering challenges. Subsurface conditions must be assessed to inform foundation design, while the surrounding environment requires careful consideration during project development.
In addition, the rehabilitation must address applicable state and federal regulatory requirements, making technical coordination and accurate site assessments important components of the design process.
As a subconsultant to GFT, SOCOTEC contributes specialized engineering expertise to help address these requirements and advance the project.
The Solution
Coordinated Engineering and Environmental Services
To support the rehabilitation design, SOCOTEC is providing a multidisciplinary approach that brings together field investigations, technical analyses, and regulatory documentation.
Evaluating Subsurface Conditions
A reliable understanding of subsurface conditions is essential for developing appropriate foundation recommendations for an existing pier.
SOCOTEC's geotechnical team is conducting investigations from the existing structure to obtain the information needed for engineering evaluations.
Services include:
Deep subsurface borings
Drilling oversight
Geotechnical laboratory testing
Engineering analyses of subsurface conditions
Development of foundation design parameters
Deep foundation analyses
Preparation of geotechnical recommendations
Findings from these investigations will help guide foundation design decisions and inform the proposed rehabilitation work.

Documenting Waterfront Conditions
Accurate surveys provide essential information about the existing site and surrounding underwater environment.
The team is performing topographic and bathymetric surveying to establish site information that can be incorporated into the design process.
By documenting both land-based and underwater conditions, these services help the engineering team evaluate the waterfront setting using reliable survey information.
Supporting Regulatory Approvals
Environmental considerations are an important aspect of waterfront construction and rehabilitation, particularly where state and federal permits are required.
SOCOTEC is assisting with environmental reviews and preparing documentation to support the permitting process.
Services include:
Pennsylvania Natural Diversity Index (PNDI) coordination
Cultural resource review
Environmental permitting support
Pennsylvania Chapter 105 permit documentation
Federal Section 404 permit documentation
These activities help address applicable regulatory requirements and provide the documentation needed for agency review.
Supporting the Future of Philadelphia's Waterfront
Through its technical contributions, SOCOTEC is helping PhilaPort advance a rehabilitation project focused on maintaining the performance and longevity of a key maritime asset.
The work supports several important project objectives:
Long-term reliability: Helping preserve the durability and functionality of existing wharf infrastructure
Engineering confidence: Informing rehabilitation design through site-specific investigations and technical recommendations
Regulatory coordination: Supporting the environmental approval process through required reviews and documentation
Operational continuity: Contributing to infrastructure improvements intended to support ongoing port activities
Once rehabilitated, Pier 82S is expected to contribute to the continued movement of goods through the Port of Philadelphia.
The project reflects SOCOTEC's ability to support complex infrastructure improvements by providing specialized expertise across multiple engineering disciplines.
