Typical 1–2%. Computed from civil subtotal (excl. bonding).
FIRE SUPPRESSION (DIV 9) ▼
HELICAL PIERS (POOR SOIL) ▼
Use in soft soils (N60 < 10) where conventional spread footings are impractical. Fence posts and light equipment pads only — BESS containers and transformers require conventional foundations.

FOOTING GEOMETRY
Select a pad preset or enter loads above, then click RUN to perform ACI 318-19 isolated footing design checks and compute concrete/rebar quantities.
c = (N60 / 8) × 1,000 psf — Bowles SPT cohesion correlation Nc = 9.0 — deep helical bearing (H/D ≥ 5, individual plate) Qt = ΣAi × c × Nc — ultimate capacity per pier T = Qt / Kt — required installation torque (ft-lbs)
Enter design load, N60, helix configuration, and pipe size — then click RUN to compute pier capacity, torque requirement, and pier count.
NEW IN v3.0 — VMI/CBS CODES | CIVIL INDIRECTS | FIRE SUPPRESSION | OIL CONTAINMENT
VMI/CBS Column: Every line item now shows VMI code (e.g., 600-EW-CLR) and CBS position (e.g., 7.1.1.1.1) for cost control integration
Civil Indirects (Div 8 expanded): Mob, Demob, Permits, Surveys, Locates, Temp Fence, Dewatering, PM/Supervision, Heating/Hoarding, Material Testing, Performance Bonding — edit sidebar for temp fence LF and bonding %
Oil Containment (Div 3 optional): Enable "Secondary Oil Containment System Required" in sidebar — adds HDPE liner + oil water separator line items to Div 3
Fire Suppression (Div 9 optional): Enable "Fire Suppression Civil Scope Required" in sidebar — adds full Div 9 with 11 line items (pipe, hydrants, FDC, water tank, etc.)
Demo (Div 1): Enable "Demolition (Brownfield)" in sidebar — adds building SF + pavement SY line items at top of Div 1
Pad Type (Div 3): "ISO Container Standard" ($36/SF) vs. "Rack-Mounted / Precision Cabinet" ($52/SF) — select in BESS Equipment sidebar
Screen Wall (Div 6): Enable "Urban Screen Wall (Masonry/CMU)" in Fencing sidebar — adds $/LF CMU screen wall row to Div 6
