》Construction Cost Estimate

Predictive process involve application of techniques that convert quantified technical project info into financial resource info by quantifying required resources cost to fulfill project scope
Applied during each phase of project life cycle as project scope is defined, modified & refined

》Major advantages of making solid construction cost estimate:

-Improve Plan
-Save Money
-Allow to Make Better Bid Comparisons
-Reduce Risk
-Cut Down on Change Orders

》Cost Included in Construction Cost Estimate

-Contingency & Variance
-Equipment
-Indirect Cost
-Labor
-Material
-Professional Fee
-Quality

》Estimator Cost Information source

-Historical Data
-Cost Research
-Expert Judgment

》Major Cost Estimation Techniques

-Analogous estimate
-Bottom-up estimate
-Parametric estimate
-Cost of Quality
-Delphi cost estimate
-Empirical Costing Method
-Expert Judgment
-Reserve Analysis
-Resource costing
-3-Point Estimate
-U.S. Government Accountability Office (GAO) 12-step process
-Cost Estimating Software(e.g. Monte Carlo method)
-Vendor Bid Snalysis

》What Makes a Good Cost Estimate?

-Accuracy
-Confidence Level
-Credibility
-Documentation
-Precision
-Reliability
-Risk detailing
-Uniformity
-Validity
-Verification

》Inaccurate Project Cost Estimate Causes (Most Likely)

-Lack of experience with similar projects
-Length of planning horizon & project
-Human resources
-Not fully understand work involved to complete work packages
-Expect resources to work at maximum productivity
-Divide tasks between multiple resources
-Fail to identify risk & to prepare adequate contingency plan & reserve
-Not updating cost estimate after project scope changes
-Creating hasty, inaccurate estimates because of stakeholder pressure
-Stat estimates as fixed sum, rather than ranges
-Make project fit fixed budget amount

》Construction Cost Estimate by Level of Accuracy

American Society of Professional Estimators (ASPE) classify estimates according to 5-level system.

The least accurate & reliable label is Level 1 & most accurate & reliable is Level 5.

Confusingly, some authorities such as AACE & U.S. DOE reverse numbering, designating Level 1 as most precise estimate

-Level 1:Order-of-Magnitude Estimate
(Project definition at 0-2% & accuracy of estimate is within a margin of 20-30%)

-Level 2:Construction Feasibility Estimate
(Definition range 5-20% & accuracy range 10-25%)

-Level 3:Preliminary Construction Estimate
(Project definition range 10-40% & accuracy range 10-15%)

-Level 4:Substantive Construction Estimate
(Project is > 90% defined & accuracy 5-10%)

-Level 5:Definitive Construction Estimate
(maximum accuracy (0-2% variance & virtually 100% project definition)

》Construction Estimate Classification by Accuracy & Phase

-Design Estimate
-Bid Estimate
-Control estimate
-Performance vs. Forecast Estimate
-Current Working Estimate

👉THE 3-4-5 METHOD

🚧This is an essential technique in the construction and civil engineering fields to accurately trace right angles on construction sites.

💫Based on the Pythagorean theorem, it guarantees the orthogonality of structures, ensuring their stability and proper alignment.

⭐️Application of the 3-4-5 method:

1. Measurement: Starting from an origin point, measure 3 units along a reference line and mark this point.

2. Second measurement: From the origin point, measure 4 units perpendicularly to the first line and mark this point.

3. Verification: Measure the distance between the two marked points; it should be 5 units. If this is the case, the angle formed is a right angle.

❇️This method is particularly useful for laying foundations, aligning walls, and verifying the perpendicularity of structural elements.

⏺It is simple to implement and only requires basic tools such as a tape measure.

⏺For a visual demonstration of this technique, you can refer to the following tutorial:

▶️3-4-5 method for drawing a perpendicular in construction

📍By adopting the 3-4-5 method, construction and public works professionals can ensure the precision and quality of their projects, thus contributing to the durability and safety of infrastructures.
