Quantifies the labor required for mixing, laying, vibrating, and curing concrete. Brickwork and Masonry
To fully understand the role of the Standard Data Book, it is essential to distinguish it from other core PWD documents that are often used alongside it.
The Public Works Department (PWD) of Tamil Nadu plays a pivotal role in creating and maintaining the state's public infrastructure. From government offices and educational institutions to hospitals and heritage structures, the PWD ensures structural safety, durability, and cost-efficiency. At the heart of all these engineering endeavors lies a foundational document: the . The document is organized into detailed annexes, covering
This relationship is clearly outlined in official PWD training material, which states that for these three components—detailed quantity take-offs, Standard Data, and the Schedule of Rates—are "interlinked with each other".
Engineers look here for data on brickwork, stone masonry, and plain cement concrete (PCC) foundations. It provides specific labor outputs for underground work where working conditions are constrained. 4. Superstructure and RCC Works
Engineers use this book alongside the local schedule of rates. Together, these books help calculate the total cost of schools, hospitals, and offices. The data book focuses on the amount of work and materials, while the rate book focuses on the current price of those items.
