The Blueprint in the Attic

In a cramped site office in Manila, young engineer Luis Torres stared at a blank estimate sheet. His first solo project—a two-story residential house—was due to bid in three days, but he had no idea how much gravel, sand, or cement to order.

His foreman, Mang Rudy, tossed a worn-out PDF printout onto the table. "You haven't read Fajardo?"

Luis opened the file: "Simplified Construction Estimate – Max Fajardo." The title was plain, but the pages were gold.

As he scrolled through Chapter 1, the numbers began to breathe. He learned how to compute concrete volume using the "linear meter method." Walls, columns, footings—once abstract lines on a blueprint—became measurable things. Wood forms for a 3-meter high wall? Fajardo said: multiply by 0.45 board foot per square meter. It was like a spell.

By midnight, Luis had filled his first column of quantities. But the real story began when he met an older architect at a construction supply warehouse the next morning.

The architect saw the printout peeking from Luis’s bag. "Ah, Fajardo," he smiled. "That book built half the houses in this province. When I started in the 90s, we had no software. Just Fajardo, a ruler, and a prayer. You know the story behind it?"

Luis shook his head.

"They say Max Fajardo was a site engineer who got tired of seeing contractors lose money because they over-ordered—or worse, under-ordered and halted work for weeks. So he simplified everything. He turned estimating into tables and formulas that even a high school graduate could follow. He didn't invent concrete, but he made sure no one poured it without knowing the cost."

That afternoon, Luis went back to the PDF. He wasn't just following numbers anymore—he was following a legacy. He estimated the gravel, sand, cement, hollow blocks, rebars, paint, and even nails. For the first time, his estimate matched the actual purchase orders.

The bid was won. The house was built on time. And when the client asked, "How did you know exactly how many bags of cement to order?" Luis pointed to the PDF on his tablet.

"That book," he said. "It’s like a compass for builders. It doesn't build the house for you, but it makes sure you don't get lost."

Years later, Luis would pass the same PDF—still dog-eared in digital form—to a new intern. And he would say the same words Mang Rudy told him: "You haven't read Fajardo?"

If you actually need a summary, table of contents, or practical guide based on Max Fajardo's book (without accessing the PDF), let me know and I’ll provide that instead.

"Simplified Construction Estimate" by Max B. Fajardo Jr. is a foundational Philippine reference providing tables and formulas for calculating material and labor quantities, ranging from concrete and masonry to lumber and roofing.

"Simplified Construction Estimate" by Max B. Fajardo Jr. is the foundational reference for material and labor cost estimations in the Philippine construction industry, utilized extensively by professionals for accurate project bidding [1]. The manual provides practical, time-tested tables and formulas for concrete, wood, steel, and electrical components, streamlining the estimation process for students and engineers [1].

Simplified Construction Estimate by Max B. Fajardo Jr. is widely considered the "Bible" of construction estimation in the Philippines. It is an essential resource for students, civil engineers, and contractors who need a practical, step-by-step guide to quantifying materials and labor for various building projects. Core Strengths

Practicality and Simplicity: True to its name, the book breaks down complex engineering concepts into easy-to-follow formulas. It is designed for real-world application rather than just theoretical study.

Comprehensive Coverage: The book covers everything from earthwork (excavation and backfill) to finishing works (painting, tiling, and roofing). It provides detailed tables for concrete mixtures, masonry, and even electrical or plumbing estimates.

Localized Context: Because it uses standards and materials common in the Philippine setting (like CHB sizes and local wood species), it is far more relevant to local practitioners than international textbooks.

Standard Reference: Most Philippine Board Exams for Civil Engineering and Architecture reference the methods found in this book, making it a mandatory tool for licensure preparation. Areas for Consideration

Market Volatility: While the formulas for material quantities remain accurate, the labor costs and material prices listed in older editions are outdated due to inflation. Users must always substitute the book's sample prices with current market rates.

Traditional Methods: The book focuses heavily on manual calculation. While this is vital for understanding the "why" behind the numbers, modern professionals will likely want to pair this knowledge with estimation software or Excel templates.

Layout and Design: Older prints can feel dense and "old-school." The diagrams are functional but lack the polished look of modern digital textbooks. Verdict

If you are involved in Philippine construction, this book is an indispensable investment. It provides a solid foundation for anyone who wants to ensure their project estimates are accurate, professional, and profitable.

Step-by-Step Example: Estimating a CHB Wall

To prove the value of the Simplified Construction Estimate Max Fajardo.pdf, let’s solve a common problem using his method.

Scenario: A wall 5.00m long, 3.00m high. Using 4" CHB (15cm x 20cm x 40cm).

Step 1: Area 5.0 x 3.0 = 15 sq. m.

Step 2: CHB Quantity Fajardo’s constant: 12.5 pieces per sq. m. Calculation: 15 x 12.5 = 187.5 pieces (Order 190).

Step 3: Cement and Sand for Mortar (Class B) According to Fajardo’s Table (CHB Mortar per sq. m.):

• Cement: 0.25 bags / sq. m. → 15 x 0.25 = 3.75 bags (4 bags of 40kg cement)
• Sand: 0.025 cu. m. / sq. m. → 15 x 0.025 = 0.375 cu. m.

Step 4: Plastering (Two Coats)

• Cement: 0.20 bags / sq. m. per side (assume 1 side only for exterior) → 15 x 0.20 = 3 bags.
• Total Cement = 4 (mortar) + 3 (plaster) = 7 bags.

Without the PDF’s table, a novice might have bought 10 or 15 bags, wasting money, or 5 bags, stalling the project.

A. Earthworks and Excavation

The book details the methods for estimating excavation volumes, including allowances for soil expansion and compaction. It provides formulas for calculating the volume of earth to be removed based on the building's footprint and foundation depth.

The Core Philosophy: Simplicity

The book is tailored to the Philippine setting. It uses local material names (e.g., "HAWA" boards, "Coco Lumber"), local labor rates, and standard practices unique to the tropical climate. For a student or a small contractor, the PDF version of this book is a portable, searchable treasure trove that prevents over-ordering or, worse, under-construction.

Total Direct Cost Formula

[ \textDirect Cost = \sum (\textMaterial Cost + \textLabor Cost + \textTools/Equipment Cost) ] Then add:

• Indirect cost (overhead: 10–15%)
• Contingencies (5–10%)
• Profit (10–20%)
• VAT (12% if applicable)
