How the math works

Total = construction × (structural + MEP + civil) + geotech + specialty.

$5M × (1.5% + 2.5% + 1.5%) = $275k + $20k + $25k = $320k engineering = 6.4%.

Frequently Asked Questions

Engineering discipline fees?

Structural: 1.0–2.5% of construction cost. MEP combined: 1.5–4.0% (M $0.50–1.50/sf, E $0.30–1.00/sf, P $0.20–0.80/sf). Civil (site, grading, utilities): 1.0–3.0%. Geotech: $5–25k for soils report + foundation recommendation. Surveying: $2–15k. Specialty (acoustic, lighting, elevator, code consultant): $5–40k each. Sometimes bundled within architect's fee, sometimes direct-contract with owner. Phase work: 60% schematic/DD, 35% CDs, 5% CA.

How does this impact project budget?

Construction budgets layer hard costs (50–65%), soft costs (15–25%), financing (5–10%), contingency (5–10%), and developer fee (3–5%). Schedule risk often equals or exceeds cost risk — every month delay carries carry cost (interest, real estate tax, insurance, opportunity cost) of 0.5–1.5% of project budget. This calculator quantifies one cost component.

Owner-controlled vs GMP vs CM-at-risk?

Lump sum/GMP: contractor takes risk above guaranteed maximum price, owner pays for change orders. CM-at-risk: open book, fee + GMP, more transparent. Construction management: agent for owner, GC subcontracted directly. Design-build: single accountability, faster but less price competition. Match delivery method to project complexity and owner sophistication.

Schedule and cost contingency?

Standard contingency: 10% of hard cost for entitlement, 5–8% for construction. Schedule contingency: 60–90 days buffer past target completion. Force majeure provisions: weather, material lead time, labor strike, permit delay. Track via critical path method (CPM) schedule. Major lender draws contingent on schedule + cost variance to budget remaining within 5%.
