Does screw pile spacing affect overall foundation cost?

Yes, genuinely — closer pile spacing means more piles for the same structure, a direct, real cost factor, while wider spacing (where structurally appropriate) reduces the total pile count needed.

Spacing itself isn’t a free choice — it’s determined by your structure’s loads and the piles’ load capacity, calculated by your engineer, not simply selected to minimise cost independent of structural adequacy.

Your engineer’s design genuinely balances pile capacity, spacing, and your structure’s specific loads to arrive at an appropriate, cost-effective configuration — not something to adjust independently without proper engineering input.
