However, I can prepare a that covers the core concepts of estimating, costing, and valuation exactly as taught in that textbook. This story will walk you through a realistic civil engineering scenario, applying the principles chapter by chapter. The Old Bridge Project: A Story of Estimating, Costing, and Valuation Part 1: The Estimate – “Before a brick is laid, a pencil must sweat.” Arjun was a fresh civil engineer working with the Public Works Department (PWD) in a small district.

I cannot directly provide or reproduce the full text of Estimating, Costing and Valuation by Dr. B.N. Dutta (commonly referred to as the "Rangwala" series, though note: Rangwala is often associated with civil engineering handbooks; the more standard author for this specific title is , published by Rangwala Publications / Charotar Publishing House). Doing so would violate copyright.
Depreciation per year = (Replacement cost) / (Total life) = $120,000 / 80 = $1,500 per year
