This article explores why this book remains a cornerstone of construction mathematics, how to effectively use its methods, and where the digital PDF version fits into modern estimating workflows. Before diving into the PDF, it is crucial to understand the authority behind the text. Max B. Fajardo Jr. is a revered author in the Philippine engineering education sector. His books are known for breaking down complex engineering mathematics into digestible, practical steps.
Fajardo’s constant: 12.5 pieces per sq. m. Calculation: 15 x 12.5 = 187.5 pieces (Order 190).
If you are a student: Buy the book. It will help you pass your boards. If you are a contractor: Keep a PDF on your tablet for quick reference on site, but own the physical copy for your office. If you are a homeowner: Attempting to use this book will save you from being overcharged by local contractors by 30-40%.
5.0 x 3.0 = 15 sq. m.
Use both. Do your initial takeoff on paper using Fajardo’s factor method, then input data into a spreadsheet or software for bidding.
