Unit-05: Study Notes for DS369
Preparation of Measurement Book for BOQ
Introduction to Measurement Book (MB):
A Measurement Book (MB) is an official record used for documenting and certifying quantities of works executed on-site, forming the basis for preparing the Bill of Quantities (BOQ) and facilitating payments.
Data Required for Measurement Book:
The Measurement Book includes specific information to maintain accuracy and accountability, including:
- Identification Data:
- Project name and location.
- Contractor’s name and details.
- Measurement Book reference number and issue date.
- Name and designation of the person responsible for recording measurements.
- Work Description:
- Clearly defined description of each item measured (e.g., excavation, concreting, brickwork, flooring, painting, plumbing).
- Quantitative Data:
- Length, breadth, height/depth (dimensions of items).
- Detailed measurements, clearly recorded, and organized systematically.
- Deductions for openings, voids, or overlaps clearly indicated.
- Date of Measurement:
- Exact date and time when measurements are recorded.
- Signature and Authentication:
- Signatures of the measuring personnel, contractors, site engineers, and approving authority for authenticity.
Units for Measurement:
Standardization of units is critical for accurate and transparent measurement processes. Typical units used are:
- Length:
- Meters (m), centimeters (cm).
- Area:
- Square meters (m²).
- Volume:
- Cubic meters (m³).
- Weight:
- Kilograms (kg) or metric tons (MT).
- Number (Nos.):
- Countable items such as doors, windows, fixtures, or furniture.
Procedure for Recording Measurements in MB:
- Clearly identify and mark measured items on plans and drawings.
- Measurements must follow a consistent and logical sequence (e.g., room-wise or floor-wise).
- Avoid duplication or omissions of work items.
- Record clearly and legibly to avoid ambiguity.
- Note down any deviations, modifications, or changes clearly.
- Measurements must be checked and cross-verified by relevant authorities.
Preparation of Bill of Quantities (BOQ):
BOQ is a structured document listing quantities, descriptions, and rates of work items required in a construction project, derived directly from the Measurement Book.
Steps to prepare BOQ:
- Item Description:
- Detailed specification and description of work items (e.g., type of materials, finishes, workmanship).
- Quantity Calculation:
- Using accurate measurements from MB.
- Apply standard methods of measurement (such as IS:1200 standards in India).
- Units and Rates:
- Clearly define measurement units for each item.
- Apply rates based on current market analysis or standard schedule rates (SSR).
- Summation and Analysis:
- Sum total quantities clearly.
- Provide sub-totals for distinct categories (e.g
Sample Format for Preparation of BOQ:

Important Notes:
- Rates: Clearly specify whether rates include labor, materials, transport, taxes, overhead, and profits.
- Units: Ensure standard units of measurement (m, m², m³, kg, Nos., etc.) are consistently applied.
- Specifications: Include clear and detailed item specifications for accuracy and comparability.
- Validation: The BOQ must be signed, verified, and approved by the project architect, engineer, or competent authority.
