“Complete” Quantity survey course | day 01

Introduction

This tutorial provides a comprehensive overview of the first day of a complete quantity surveying course. It covers essential topics such as costing and estimating, which are fundamental skills for quantity surveyors. Whether you're a beginner or looking to refresh your knowledge, this guide will help you grasp the key concepts discussed in the video.

Step 1: Understanding Quantity Surveying

• Definition: Quantity surveying involves managing the costs and budget of construction projects. It ensures that projects are completed within financial constraints while maintaining quality.
• Importance: It helps in accurate budgeting, financial planning, and managing resources effectively.
• Key Roles:
  • Cost estimation
  • Cost control
  • Financial reporting
  • Risk management

Step 2: Basics of Costing and Estimating

• Costing: The process of determining the total expenses involved in a project.

  • Direct Costs: Expenses that can be directly attributed to the project (e.g., materials, labor).
  • Indirect Costs: Overhead costs not directly tied to a specific project (e.g., administrative expenses).

• Estimating: The technique of forecasting the costs associated with construction projects.

  • Methods of Estimation:
    • Unit Rate Method: Cost per unit of work.
    • Detailed Estimate: Comprehensive breakdown of all costs involved.
    • Approximate Estimate: Quick calculations based on previous similar projects.

Step 3: Relevant Tools and Techniques

• Estimating Software: Familiarize yourself with popular software tools used in quantity surveying, such as:

  • CostX
  • Bluebeam
  • Excel for basic estimates

• Takeoff Processes: Learn how to perform a takeoff, which involves measuring quantities from drawings to prepare cost estimates.

Step 4: Common Pitfalls to Avoid

• Inaccurate Measurements: Ensure precision in measurements to avoid underestimating or overestimating costs.
• Ignoring Overheads: Always account for indirect costs to ensure the total estimate reflects all expenses.
• Underestimating Contingencies: Include a contingency budget to handle unforeseen expenses during construction.

Step 5: Practical Applications

• Real-World Scenarios: Practice estimating costs for different types of projects, such as residential, commercial, and infrastructure.
• Case Studies: Analyze past projects to understand how costing and estimating were handled successfully or where issues arose.

Conclusion

In this tutorial, we covered the fundamentals of quantity surveying, focusing on costing and estimating. Key takeaways include understanding the definitions and roles in quantity surveying, the various methods of costing and estimating, and the importance of avoiding common pitfalls. As you progress in your quantity surveying journey, practice these concepts through real-world applications and utilize estimating tools to enhance your skills.
