Mastering Quantity Surveying: Essential Tips for Accurate Cost Estimation
Quantity Surveying is a meticulous method used by appraisers to estimate the reproduction cost—this is the cost to create a new replica—of an improvement or structure. It involves detailed cost estimation, which encompasses all materials, labor, and overhead required. Understanding this process equips you to make more precise and dependable property appraisals.
What is Quantity Surveying?
Quantity surveying consists of a detailed analysis of each component of the property. This includes:
- Comprehensive listing of materials
- Labor costs involved in building the new improvement
- Overhead expenditure required to organize and expedite construction activities
Example Quantity Survey Estimate
To illustrate how a quantity survey is conducted, consider a simplified example where a reproduction cost is estimated. Here’s a breakdown:
| Item | Cost |
|---|---|
| Site preparation | $5,000 |
| Cement | $10,000 |
| Masonry | $15,000 |
| Lumber | $25,000 |
