Check and verify all wall sizes, footer sizes, and concrete PSI requirements. It’s not unusual to see 16-inch footers where code requires 12 inches, or poured walls at 10 inches where 8 inches are required. Concrete is also commonly over-specified, using 3,500 or 4,000 PSI concrete where 3,000 will work just as well. Savings of $350 per unit are common.
