- Structural Drawings – Foundation plans, beam layouts, column details, reinforcement details.
- MEP Drawings (Mechanical, Electrical, Plumbing) – Layouts for HVAC, electrical wiring, plumbing, and fire protection.
- Site Survey & Soil Investigation Report – Helps in foundation design and material selection.
- BOQ Format & Standard Codes – FIDIC, SMM (Standard Method of Measurement), NRM (New Rules of Measurement), CESMM (Civil Engineering Standard Method of Measurement).
2. Measurements & Estimation Tools
- Quantity Take-off Sheets – For recording measurements of materials and labor requirements.
- Software Tools – AutoCAD, Revit, CostX, PlanSwift, Bluebeam, or MS Excel for calculations.
- Measurement Units & Conversion Factors – Understanding metric or imperial unit conversions.
3. Cost & Pricing Data
- Material Price List – Updated cost of construction materials (cement, steel, bricks, etc.).
- Labor Rates – Hourly/daily wages for different trades (masons, carpenters, electricians).
- Equipment & Machinery Costs – Rental or purchase costs of cranes, excavators, concrete mixers.
- Subcontractor Quotes – Pricing from external contractors for specialized work.
- Market Rate Analysis – Regional variations in construction costs.
4. Work Breakdown Structure (WBS)

Converting Architectural, Structural, MEP Drawings, Site Survey Reports, and BOQ Formats into a Bill of Quantities (BOQ)
A Bill of Quantities (BOQ) is created by systematically extracting data from project documents and translating them into itemized quantities with pricing. Below is a step-by-step process to convert each input into a BOQ.
1. Understanding Project Documents & Extracting Quantities
Each document provides specific data that contributes to different sections of the BOQ.
a) Architectural Drawings → Civil & Finishing Works in BOQ
🔹 What to extract?
- Dimensions for walls, doors, windows, ceilings, and floor finishes.
- Area of plastering, tiling, and painting.
- Number of doors/windows with sizes.
🔹 BOQ Sections
- Site preparation & excavation (if required)
- Masonry works (brick/block walls)
- Floor, wall, and ceiling finishes (tiling, plastering, painting)
- Joinery & woodwork (doors, windows, cabinetry)
b) Structural Drawings → Concrete, Steel, and Foundation in BOQ
🔹 What to extract?
- Volume of concrete for foundations, beams, slabs, and columns.
- Quantity of reinforcement (kg or tonnage).
- Formwork area (m²) for casting concrete.
🔹 BOQ Sections
- Earthwork (excavation, filling, compaction)
- Reinforced concrete works (footings, slabs, beams, columns)
- Steelworks (reinforcement bars, structural steel, welding)
c) MEP Drawings → Electrical, Plumbing, HVAC in BOQ
🔹 What to extract?
- Length of conduits, pipes, and ducts.
- Number of electrical fixtures (lights, switches, sockets).
- Number of plumbing fixtures (taps, sinks, WCs).
- Equipment specifications (air conditioners, pumps, panels).
🔹 BOQ Sections
- Electrical works (wiring, conduits, switches, panels)
- Plumbing works (water supply, drainage, sanitary fittings)
- HVAC works (ducting, air conditioning, ventilation)
d) Site Survey & Soil Investigation Report → Foundation & Earthwork in BOQ
🔹 What to extract?
- Type of soil and excavation depth required.
- Need for soil improvement or special foundation work.
🔹 BOQ Sections
- Site clearing & preparation
- Excavation & backfilling
- Soil stabilization (if required)
e) BOQ Format & Standard Codes → Structuring BOQ Correctly
- Use standard BOQ templates (FIDIC, NRM, CESMM, SMM7, etc.).
- Follow measurement units (m³ for concrete, m² for tiling, kg for steel).
- Ensure standard descriptions (e.g., "25 MPa reinforced concrete for footings").
2. Measuring Quantities (Quantity Take-off - QTO)
- Use AutoCAD, Revit, or PlanSwift to extract exact quantities.
- Manually measure from scaled drawings using rulers & formulas.
- Use Excel sheets for calculations & structuring.
3. Preparing BOQ (Example Format)
| Item No. | Description | Unit | Quantity | Unit Rate | Total Cost |
|---|---|---|---|---|---|
| 1.0 | Earthwork | ||||
| 1.1 | Site clearance & grubbing | m² | 500 | X | X * 500 |
| 1.2 | Excavation for foundations | m³ | 120 | X | X * 120 |
| 2.0 | Concrete Works | ||||
| 2.1 | Reinforced concrete for footings | m³ | 50 | X | X * 50 |
| 2.2 | Formwork for beams & slabs | m² | 200 | X | X * 200 |
| 3.0 | Masonry Works | ||||
| 3.1 | 230mm Brickwork walls | m³ | 100 | X | X * 100 |
4. Applying Costing & Finalizing BOQ
- Get material rates from suppliers.
- Use labor rates for different tasks.
- Add overheads & profit margin (typically 5–15%).
- Review & validate before finalizing.
Conclusion
To convert project documents into a BOQ, a Quantity Surveyor (QS) needs to:
✅ Extract relevant measurements from drawings & reports.
✅ Use standard BOQ formats for structuring.
✅ Perform accurate quantity take-offs using tools.
✅ Apply market rates for costing.
✅ Review & validate before finalizing.
This structured approach ensures accuracy and efficiency in BOQ preparation. 🚀

🔥 Step 3: AI Processing (Python)
📌 1. cost_estimator.py (AI Model for Cost Prediction)
import sys
import json
import numpy as np
from sklearn.linear_model import LinearRegression
def predict_cost(materials):
X_train = np.array([[10], [20], [30]]) # Sample Training Data
y_train = np.array([1000, 2000, 3000]) # Sample Cost Data
model = LinearRegression()
model.fit(X_train, y_train)
total_cost = sum([model.predict([[m['quantity']]])[0] for m in materials])
return round(total_cost, 2)
if __name__ == "__main__":
materials = json.loads(sys.argv[1])
print(predict_cost(materials))
📌 2. blueprint_ocr.py (Blueprint OCR Processing)
import sys
import pytesseract
import cv2
import numpy as np
def extract_text(image_path):
img = cv2.imread(image_path)
text = pytesseract.image_to_string(img)
return text
if __name__ == "__main__":
image_path = sys.argv[1]
print(extract_text(image_path))
🔥 Step 4: Frontend (Bootstrap + PHP)
📌 1. index.php (Login Page)
<!DOCTYPE html>
<html lang="en">
<head>
<title>Login</title>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/css/bootstrap.min.css">

<body>
<div class="container">
<h2>Login</h2>
<form action="auth.php" method="POST">
<input type="text" name="username" placeholder="Username" required>
<input type="password" name="password" placeholder="Password" required>
<button type="submit">Login</button>
</form>
</div>
</body>
</html>
📌 2. dashboard.php (Main Dashboard)
<?php session_start(); if (!isset($_SESSION['user_id'])) header("Location: index.php"); ?>
<!DOCTYPE html>
<html lang="en">
<head>
<title>Dashboard</title>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/css/bootstrap.min.css">
</head>
<body>
<div class="container">
<h2>Dashboard</h2>
<a href="materials.php">Manage Materials</a>
