Standardizes the laying of various flooring materials including cement flooring, ceramic tiles, vitrified tiles, marble, granite, and interlocking paver blocks. 9. Painting and Distempering

| Type | Width (mm) | Height (mm) | |------|------------|--------------| | Main entrance | 1200 | 2100 | | Room door | 900 | 2100 | | Toilet door | 750 | 2100 |

While the SoR prices fluctuate due to inflation, market dynamics, and regional premiums, the Standard Data Book constants remain fixed. This separation ensures the PWD does not need to rewrite engineering fundamentals every year. 🚀 Modern Digitization: The e-Path to Smart Estimation

Tamil Nadu PWD Building Practice Standard Data Book: The Definitive Guide for Construction Excellence This separation ensures the PWD does not need

The Standard Data Book is a regulatory publication that legalizes and standardizes construction inputs. It translates raw engineering concepts into standardized data points. Key Functions

The document is often used in conjunction with the Schedule of Rates (SoR) to determine current pricing for materials and labor. It includes detailed breakdowns of: Key Functions The document is often used in

Unlike the CPWD which allows a 12mm plaster thickness for walls, the Tamil Nadu book standardizes (1:5 ratio) and 12mm for internal walls (1:4 ratio).

Defines the quantity of primers, wall putty, acrylic emulsions, synthetic enamels, and weather-proof coats needed per unit area, alongside labor coefficients for painters. The Role of the Data Book in Rate Analysis

The Tamil Nadu PWD releases revised Schedule of Rates annually. For instance, in 2025, the government released a three-volume SOR with an overall increase of nearly 5% across key construction items, adding 183 new items to the list. The SOR for 2024 set cement at ₹298 per bag and steel at ₹56,000 per metric tonne, factoring in conveyance charges and wages. All of these rates are derived directly from the Standard Data Book. To further ensure accuracy, the SOR incorporates factors such as the Wholesale Price Index, TANCEM rates for cement, SAIL rates for steel, and past five years of construction data. and the application of primers

The Standard Data Book does not list direct monetary values. Instead, it works in tandem with the annually updated .

Tamil Nadu PWD Building Practice Standard Data Book is a foundational technical resource used by engineers and contractors to standardize construction estimates and execution across the state. It serves as the bridge between the Standard Schedule of Rates (SoR)

Specifies the material quantities for internal and external plastering of varying thicknesses, decorative pointing, and the application of primers, distempers, emulsions, and weather-resistant paints. 7. Flooring and Tiling

Covers stone masonry standards for retaining walls and basements. Finishing Works (Plastering, Painting, and Flooring)

Assistant and Executive Engineers use the data constants to prepare Detailed Project Reports (DPR). It ensures public funds are allocated based on empirical engineering metrics rather than guesswork. Contractors and Project Managers
