How the math works

Architect = cost × fee %. Sub-consultants = architect × sub %. Total = arch + subs + reimbursables.

$5M × 7% = $350k arch + 40% subs $140k + 5% reimb $17.5k = $507,500 total design.

Frequently Asked Questions

Architect fee benchmarks?

Single-family residential: 8–18% of construction cost ($2k–25k+ for design + drawings). Multifamily: 4–7%. Commercial office: 5–9%. Healthcare/lab/institutional: 7–12% (complexity premium). Civic/public: 6–10%. Stipulated sum AIA B101 contract standard. Phases: schematic (15%), design development (20%), construction docs (40%), bidding/CA (15%), CA close-out (10%). Sub-consultants (structural, MEP, civil): 30–50% pass-through of arch fee or separately invoiced.

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%.
