Driven foundation piles installed to capacity, on schedule.
Pile Driving
We drive foundation piles to design capacity with production-rate efficiency, supporting structures on Boston's challenging ground. Pile types and installation criteria are engineered to the site's subsurface conditions.
Cross-section
Callouts
Select a numbered part below to read what it is and what it does.
- Delivers controlled energy through a helmet and cushion to advance the pile; impact hammers also let us record blow counts that confirm resistance.
- Steel H-pile, steel pipe, or precast concrete — the type is selected by the engineer for the loads, ground conditions, and drivability of the site.
- Side resistance develops along the pile shaft as it passes through fill and clay, contributing to the total geotechnical capacity.
- The tip is driven to the dense glacial-till stratum, where driving resistance (blow count) confirms capacity against the geotechnical criteria.
Typical spec
Plain-language view of the same typical ranges.
- Kinds of piles
- Steel H / pipe / precast
- The pile materials we can drive.Steel H / pipe / precast chosen for load, drivability, and subsurface per the foundation design.
- How deep piles go
- 30–120 ft
- Typical driven depth to reach firm ground.Embedment to the bearing stratum; tip elevation governed by capacity, not a fixed depth.
- Driving equipment
- Impact / vibratory
- The hammer used to install the piles.Impact / vibratory selected via wave-equation drivability analysis (e.g., GRLWEAP).
- When a pile is done
- ≈ 5–20 blows/in at refusal
- The rule that says a pile has reached capacity.Blow-count resistance to target depth; verified by dynamic/static testing where specified.
How it goes in
- 01
Mobilize & lay out
Rigs and piles are mobilized and the pile layout is surveyed to the foundation plan.
- 02
Drive to criteria
Piles are driven with an impact or vibratory hammer to the depth or resistance criteria set by the geotechnical engineer.
- 03
Verify capacity
Installation is documented and capacity is confirmed against the driving criteria (and dynamic testing where specified).
