Explore the foundation, end to end.

Drag the knobs and click through every output — the parsed boring log, a 3D pile in the soil, capacity with its uncertainty band, the budget, the CSI-31 spec, and a buildable DXF — without leaving the page. This preview runs a sample Boston boring; live PDF upload arrives with early access.

Recommended element

7-inch micropile, rock-socketed

Shallow competent bedrock favours a small-diameter, rock-socketed micropile installable in low headroom.

Preliminary
Allowable capacity versus depth for the recommended foundation elementDepth increases downward on the vertical axis; allowable capacity in kips runs along the horizontal axis. The shaded region is the P10 to P90 uncertainty band, the solid line is the P50 median, and the marker is the design capacity of 108 kips at 93 feet.050100150200250020406080100Allowable capacity (kips)Depth (ft)108 kips @ 93 ft · FS 2.5
