Concrete Calculator — Construction Estimate Web App
Built during my SDE Internship at Litvik Software Labs to help users calculate concrete volume requirements with ease and accuracy.
Tech Stack
Problem Solved
Manual concrete calculations for various structures often led to mistakes and inefficiencies on construction sites. This app automates volume estimation, improves accuracy, and provides downloadable reports for quick referencing.
- Dynamic forms based on structure type
- Accurate volume/unit calculations
- PDF report download with saved entries
- Unit selection: meters or feet
Key Features
📐 Dynamic Calculation Form
Lets users input structure type, dimensions, and units for real-time volume calculation.
📤 Save & Download Entries
Users can store previous entries and export them to PDF for record keeping.
📏 Unit Flexibility
Supports both metric (meters) and imperial (feet) unit selection.
🧾 Structured Output
Cleanly designed reports for users and supervisors to review.
System Architecture
*Architecture shows flow from frontend input to backend PDF generation.
