What format does this book follow and what standards does it reference?

All 3D-LABS engineering books follow a practice-first structure: each chapter is built around worked examples, engineering diagrams, and real-world applications. Where applicable, content references Indian Standards (IS codes, BIS), international standards (ASME, AISC, IEC, IEEE), and India-specific regulations such as IGBC guidelines for green construction. Every formula includes units, assumptions, and the applicable standard edition.

Is this book relevant for Indian engineering practice and IS codes?

Yes. 3D-LABS books are specifically written for Indian engineering context. Content includes Indian Standards (IS 456, IS 800, IS 1893, SP 46, etc. where relevant to the topic), Indian industry norms, and practical examples from Indian project environments. This distinguishes 3D-LABS books from generic international textbooks that may not reflect Indian code requirements or local practice.
