Simplified Construction Estimate Max B. Fajardo Jr. is a foundational textbook used primarily in the Philippines for teaching the fundamentals of construction cost estimation. It is designed to be a practical guide for students, contractors, and engineers.
Below is a draft summary of the text's key components and structure based on the manual's standard content: Overview of the Manual
The book focuses on providing a systematic approach to quantifying materials and labor for various construction phases. It emphasizes "simplified" methods—using pre-calculated constants and tables to speed up the estimation process without requiring complex calculus or advanced physics. Core Sections and Topics Concrete Works
: Methods for calculating cement, sand, and gravel for footings, columns, beams, and slabs. It typically includes tables for different concrete mixtures (Class A, B, C).
: Estimating the number of concrete hollow blocks (CHB), including the volume of mortar for laying and plastering. Metal Reinforcement (Steel)
: Detailed techniques for determining the weight and length of reinforcing bars (rebars), including considerations for hooks, bends, and splices. Carpentry and Joinery
: Calculations for board feet in wooden frames, floorings, and ceiling joists. Roofing and Tinsmithry Simplified Construction Estimate Max Fajardo.pdf
: Estimating G.I. (Galvanized Iron) sheets, gutters, and flashing based on effective coverage areas. Tile Work and Finishes
: Calculating the number of tiles and the required adhesive/grout for specific floor and wall areas. Key Estimation Principles Taught Area and Volume Method
: Breaking down architectural plans into geometric shapes to find total surface areas or volumes. The "Constant" Factor
: Using Fajardo’s signature tables that provide a "multiplier" for materials (e.g., 0.054 bags of cement per square meter of plastering). Wastage Allowance
: Guidance on adding 5% to 10% to the net estimate to account for on-site material loss and breakage. Usage Context The text is frequently used to prepare a Bill of Materials (BOM) Bill of Quantities (BOQ)
, which are essential for securing building permits and project bidding. Simplified Construction Estimate Max B
You might ask: "Why look for the PDF when I can buy the physical book?" While the physical book costs around PHP 400-500, the PDF offers unique advantages:
In the construction industry, the ability to accurately estimate costs is the difference between a profitable project and a financial disaster. "Simplified Construction Estimate" by Max B. Fajardo is widely regarded as an essential handbook for Filipino engineers, architects, and construction managers. Part of Fajajar’s celebrated series of technical reference books, this volume bridges the gap between complex theoretical calculations and the practical realities of the Philippine construction setting.
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). Why the PDF Version
Step 3: Cement and Sand for Mortar (Class B) According to Fajardo’s Table (CHB Mortar per sq. m.):
Step 4: Plastering (Two Coats)
Without the PDF’s table, a novice might have bought 10 or 15 bags, wasting money, or 5 bags, stalling the project.
Many university libraries (UP Diliman, Mapua, DLSU) have digital vaults where students can log in and download the PDF for free as part of their enrollment. Check your university’s e-library.
