How The Dwyer Company Stabilized North Adams High School with an 89-Pier Foundation System
- Project Type: Commercial
- Project Services: Deep Foundation Systems, Push Piers
When Ohio Valley School District noticed uneven settling at the southeastern and southwestern wings of North Adams High School, the structural integrity of active classrooms was at risk. In close collaboration with Civil Solutions, The Dwyer Company engineered and installed a push pier system to permanently stabilize the facility. A total of 89 push piers were installed with a capacity of 25 kips each, strategically positioned to halt settlement and protect the school structure, proving that even large-scale educational facilities experiencing differential settlement can achieve permanent structural stability with the right expertise and coordination.

The Challenge:
The primary challenge was halting progressive foundation settlement affecting two separate wings of an occupied school building—requiring our team to carefully navigate active classroom schedules, student safety protocols, and establish stable working conditions around an operational educational facility. Conventional underpinning methods couldn’t achieve the required load transfer and settlement control across 89 pier locations without extensive excavation and costly disruption to the academic year, given the scale of the project and the need for precision load distribution across multiple settlement zones.
The Solution: Large-Scale Push Pier Array with Engineered Load Distribution
The Dwyer Company, in partnership with Civil Solutions engineering, designed and installed an 89-pier push pier system that achieved permanent load transfer to competent bearing strata beneath both affected wings. The solution required detailed pre-installation planning, precise pier spacing calculations across multiple foundation sections, and careful coordination with school operations to minimize educational disruption.
The installation process involved establishing work zones that maintained safe access for students and staff, executing systematic pier installation across the southeastern and southwestern wings to engineered specifications, and implementing load testing protocols to verify 25-kip capacity at each location. Each pier was hydraulically driven to refusal in load-bearing soil, ensuring uniform support across the entire affected foundation area.
The entire installation was completed during the 2024-2025 academic year, allowing Ohio Valley School District to maintain normal school operations while providing North Adams High School with a permanently stabilized foundation system and eliminating the risk of continued settlement that threatened classroom safety and structural integrity.

Why Push Piers for Educational Facilities?
The Dwyer Company’s push pier foundation system delivered the structural stability and installation efficiency required for this large-scale school repair project.
-
Permanent Settlement Control
Push piers transferred building loads to competent bearing strata beneath the settling foundation, permanently halting the differential settlement threatening structural integrity in both affected wings. -
Minimal Operational Disruption
The push pier installation method allowed foundation repair work to proceed around normal school schedules, eliminating the need for building closures or classroom relocations that traditional underpinning would have required. -
Scalable Solution
The 89-pier array provided comprehensive coverage across both settlement zones, with each pier independently driven to refusal to ensure uniform support regardless of varying soil conditions beneath different building sections. -
Engineered Load Capacity
Each 25-kip pier was designed in partnership with Civil Solutions to support calculated structural loads, providing verified performance rather than estimated capacity. -
Long-Term Reliability
The push pier system provides permanent foundation support that will protect North Adams High School's structural integrity for decades, eliminating the risk of recurring settlement that would require repeated interventions.
The Impact: Safe Classrooms and Preserved Educational Continuity
Cost-Effective Solution
The push pier system eliminated the need for complete foundation replacement or extensive building modifications, delivering budget optimization while meeting rigorous structural performance standards for an occupied school facility.
Schedule Preservation
Completing the foundation stabilization during the academic year without classroom closures prevented educational disruption and avoided the costly logistics of temporary classroom relocations.
Zero Structural Settlement
Most critically, the 89-pier system permanently halted foundation settlement affecting two major wings of North Adams High School—providing Ohio Valley School District with verified structural stability that protects students, staff, and the community's educational infrastructure investment for generations to come.
