Understanding and Quantifying Civil Construction: A Comprehensive Exploration

The realm of civil construction involves diverse methods and units of measurement, designed to capture the intricacies of nature, shape, and size. Additionally, these measurements play a crucial role in determining fair payments to contractors. Let’s delve into the principles that underpin these methods and explore a detailed breakdown of units of measurement for various civil engineering works.

Units of Measurement

1. Single Units Work

Items like doors, windows, and trusses are expressed in numbers, capturing the essence of individual components.

2. Linear Measurements

Linear works, such as cornice, fencing, and handrails, are quantified in running meters (RM), emphasizing length.

3. Areal Surface Measurements

Tasks involving surface area, like plastering and partitions, are expressed in square meters (m2), providing a comprehensive view of the space covered.

4. Cubical Contents

Projects with volume considerations, such as earthwork and masonry, are measured in cubic meters, reflecting the three-dimensional nature of the work.

Units of Measurement for Various Civil Engineering Works

Sl. No. Particulars of Item Units of Measurement Units of Payment
1 Earthwork CUM Per CUM
2 Concrete CUM Per CUM
3 Damp Proof Course SQM Per SQM
4 Brickwork CUM Per CUM
5 Stone Work CUM Per CUM
6 Wood Work CUM Per CUM
7 Steel Work Quintal Per Quintal
8 Roofing CUM Per CUM
9 Plastering, Points, and Finishing SQM Per SQM
10 Flooring SQM Per SQM
11 Rainwater Pipe/Plain Pipe RM Per RM
12 Steel Wooden Truss Each Per Each
13 Glass Panels (Supply) SQM Per SQM
14 Fixing of Glass Panels or Cleaning Each Per Each

Note:

  • SQM = Square meter
  • CUM = Cubic meter
  • RM = Running meter

Methods for Measurement of Civil Engineering Works

Understanding the methods for measurement is vital. The rules outlined in IS-1200 guide these measurements. Here are some general rules:

  1. Measurement covers all aspects of finished work, encompassing materials, transport, labor, fabrication tools, and plant usage.
  2. Sequencing in booking follows the order of length, breadth, and height or thickness.
  3. Measurements adhere to specific tolerances for linear, area, and cubic contents.
  4. Different conditions and nature warrant separate measurement under distinct items.
  5. The bill of quantities provides a comprehensive description, including materials, proportions, and workmanship.
  6. For masonry or structural concrete, measurements are segmented based on vertical levels, from foundation to plinth, plinth to the first floor, and so on.
