Here is a breakdown of its purpose, contents, and application: Primary Purpose Standardization
: Includes hire charges and operational data for plants and machinery used in construction.
The Standard Data Book is a comprehensive compilation of operational data. It defines the exact quantities of labor, materials, and machinery required to complete a specific unit of construction work.
| Element | Min steel % | |---------|-------------| | Slab | 0.12% (HYSD) | | Beam | 0.20% | | Column | 0.80% |
Look up the exact item of work (e.g., "Reinforced Cement Concrete 1:1.5:3 for lintels and slabs").
: Forms the mandatory framework for creating administrative and technical sanctions. 🏗️ Core Components of the Document
Unlike a simple price list, the Standard Data Book provides the breakdown of resources
Contract conditions across Tamil Nadu frequently stipulate: "The entire work should be carried out as per specifications in the National Buildings code and Taminadu [sic] Building Practice." In many official tenders, the rates for RCC works are stated to "include treatment by curing as per TAMILNADU BUILDING PRACTICE". The three documents—the Standard Data Book for rates, the TNBP for methodology, and the Building Code for general administration—form a "digital twin" of the state's construction protocol.
Tamil Nadu PWD Building Practice Standard Data Book is an essential technical manual used by the Public Works Department (PWD) and other state departments (like the Rural Development and Panchayat Raj Department ) to standardize construction practices across the state.
: Lists the human effort required for tasks like earthwork, dismantling, and masonry, ensuring consistency in productivity expectations across various regions.
Private bidders use these constants to calculate actual project overheads. It allows contractors to find the exact threshold where a government project becomes financially viable. Valuation and Audit Officers
Despite its strengths, the system has its challenges. Keeping the data book constantly updated to reflect real-world market volatility is an ongoing process. However, the PWD is actively working to enhance its effectiveness. A key initiative is the to ensure transparency in awarding contracts. The department is also focusing on preventive maintenance to extend the life of its assets and is committed to ensuring all building practices conform strictly to Indian Standard (IS) Codes .
One of the most critical sections, it specifies the exact proportions of cement, sand, coarse aggregate, and water needed for various concrete mixes (such as M15, M20, M25). It defines the standard labor inputs required for mixing, transporting, placing, vibrating, and curing concrete. 3. Masonry (Brick and Stone)
While closely linked, these two documents serve entirely different functions in project estimation: Standard Data Book Schedule of Rates (SOR) Quantities of inputs (Material, Labor, Equipment). Unit monetary costs of inputs and finished items. Volatility
Factor in the allowed percentage or hourly rate for mixers, vibrators, and hoists.
The book multiples the quantity by the district-specific rate (A, B, C zones—Chennai being Zone A, highest rates) to get the final exclusive tender value.
State audits (such as those by the Accountant General) rely heavily on this data book to verify that public funds were utilized correctly during construction. It protects both the engineer and the government from financial discrepancies.
