# Core Drilling Cost Calculator
Location: /core-drilling-costs-calculator/


## Context
A web-based tool for Carolina Precision Core Drilling (Charlotte, NC) used to estimate costs for concrete, brick and cement block core drilling in floors and walls.

## Capabilities
- Calculate horizontal (Wall) and vertical (Floor) drilling costs.
- Supports diameters: 1 inch to 16 inch.
- Supports depths: 6 inch to 24 inch.
- Standard mobilization fee: $200.00.

## Programmatic Interface (JavaScript Bridge)
The following functions control the flow:
- updateStep('direction', 'Wall' or 'Floor'): Starts the estimate.
- updateStep('height', 'low' or 'high'): REQUIRED for Wall estimates (under/over 5ft).
- updateStep('size', value): Sets diameter (1-16)[cite: 2, 4].
- updateStep('depth', value): Sets thickness (6-24)[cite: 3, 4].
- formatText(tag): Enters quantity[cite: 5].
- aiSubmit(): Adds the configured item to the estimate[cite: 5].

## Pricing Logic
The pricing is look-up based and varies by diameter and depth. 
Note: Sizes 11 inch, 13 inch, and 15 inch are currently N/A (not available).
