Estimating in Construction: Building a Strong Foundation

Estimating in Construction: Building a Strong Foundation

Learning Objective

At the end of the lesson, you will be able to make accurate and informed estimates for construction projects.

Introduce the main goal of the lesson and what students will achieve by the end of it.

What do you already know about estimating in construction?

What is Estimating?

Estimating is the process of calculating the approximate cost, time, and materials needed for a construction project.

Define the concept of estimating in construction and its importance.

Factors Affecting Estimates

Several factors can affect estimates, including project size, location, materials, labor, and unforeseen obstacles.

Explain what factors can impact the accuracy of estimates.

Types of Estimates

There are three types of estimates: preliminary, detailed, and final. Each type is used for different stages of a construction project.

Discuss the different types of estimates and their purposes.

Tools for Estimating

There are several tools and software available to assist with estimating, including spreadsheets, cost databases, and building information modeling (BIM).

Introduce students to the various tools and software available for estimating.

Practice Makes Perfect

Estimating is a skill that requires practice. Try estimating the cost of materials for a small project like building a birdhouse.

Provide an interactive element where students can practice estimating.

The Importance of Accuracy

Accurate estimates are crucial for staying within budget, managing resources, and ensuring the success of a construction project.

Emphasize the importance of accurate estimates in construction.

Review and Summary

Estimating in construction is the process of calculating the approximate cost, time, and materials needed for a project. There are several factors and tools that can affect estimates, and accuracy is crucial for success.

Summarize the main points of the lesson and review key concepts.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
