Frequently Asked Questions
Tap fee benchmarks?
Water tap: $2–25k+ per unit (urban infill cheaper, exurban expensive). Sewer tap: $3–35k. Gas service: $1–8k. Electric service: $1–12k. Stormwater: $1–8k. Reuse/reclaimed: $5–15k. Capacity charge (impact-style): $5–50k for higher-demand uses. Western US (CA, CO, AZ, NV): tap fees 2–4x national average due to water scarcity. Plan ahead — 'will-serve' letter from utility 30–90 days lead time, formal capacity reservation 60–180 days.
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%.
