#### Formula & Methodology

Step 1 — Adjusted Base Rate:

Adjusted Rate ($/sq ft) = Base Finish Rate × (1 + Condition Adjustment) × Retail Type Multiplier × Location Factor

Step 2 — Base Construction Cost:

Base Cost = Adjusted Rate × Square Footage

Step 3 — MEP Delta (scope above base rate):

MEP Delta = max(0, (HVAC + Plumbing + Electrical costs) − (Base Rate × 30% × Sq Ft))

The base construction rate already includes approximately 30% for standard MEP systems. The delta captures only the additional cost when the selected scope exceeds that baseline.

Step 4 — Hard Cost Subtotal:

Hard Costs = Base Cost + MEP Delta + Storefront Cost

Step 5 — Soft Costs (12% of Hard Costs):

Soft Costs = Hard Costs × 0.12 — covers architecture, engineering, permit fees, and project management.

Step 6 — Contingency (10%):

Contingency = (Hard Costs + Soft Costs) × 0.10

Step 7 — Total Project Cost:

Total = Hard Costs + Soft Costs + Contingency + FF&E

Step 8 — Out-of-Pocket:

Out-of-Pocket = max(0, Total Project Cost − TI Allowance)
