An inter-city structure had been demolished, and the site was being repurposed to build a Canopy for an exhibit area. Micro-Piles were originally specified but the Engineer and GC (Intech), decided to value engineer the project due to suspect soil conditions and potential issues with subsurface obstructions.
Project Summary:
- Helical Pile Type: SS 175 (1 3/4″ square shaft) transitioning to 2 7/8″ Pipe
- # of Helical Piles: 21
- Location: Philadelphia, PA
- Installation Depth: 11′ to 14′
- Helix Plates/Ultimate Pile Capacity: 8″ 10″ 12″ / 14 Kips 7,500 ft-lbs. Torque
- Equipment Used: CAT 315 Excavator
- Challenge/Unique Aspect: The soil borings and a field report confirmed that a prior structure had been demoed, but the site had not been properly remediated. Helicals were used as a cost-saving alternative to micro-piles and to navigate the trash and fight through sub-surface debris.
