Role of an Estimator For Building Construction Projects

The role of an estimator in building construction projects is super important. Imagine you're constructing a building, whether it's a residential complex, an office tower, or even a mall. The estimator is the person who figures out how much the entire thing is going to cost before even a single brick is laid. Now, let's break down what an estimator does in a simple, conversational way, just like we’d talk over chai.

1. Before Construction: Pre-Construction Estimation

Before the construction work begins, the estimator's main job is to estimate the total cost of the project. This is where all the calculations happen—how much material is needed, how many workers will be required, and what kind of machinery will be used.

Example:

Let’s say you’re going to build a 5-storey residential building. The estimator looks at the drawings and plans and starts working. They’ll calculate how many bricks, bags of cement, and steel rods will be required for the structure. They’ll also estimate how many laborers are needed for each phase, like masonry work, plastering, and finishing.

Not just this, the estimator will consider market prices. For instance, if the cost of cement is fluctuating, the estimator has to keep that in mind while making the budget. They’ll create a detailed Bill of Quantities (BOQ) which is basically a long list that breaks down each material, labor, and piece of equipment needed for the project.

2. During Construction: Tracking and Adjusting Costs

Once construction begins, the estimator doesn’t just sit back and relax. They’re constantly keeping an eye on the expenses to make sure the project is staying within the budget. If the project runs into any surprises, like changes in design or material shortages, the estimator has to adjust the cost estimates accordingly.

Example:

Let’s say the client suddenly decides they want a penthouse on the top floor of the building. Now, the estimator will have to go back to the drawing board and figure out how much extra material is needed, what additional labor will cost, and how long it’ll take. If steel prices go up, the estimator will adjust the budget to reflect the increase. They’re the ones who make sure the project doesn't overshoot its budget too much.

Also, the estimator will negotiate with suppliers. If cement prices are going up, they’ll try to lock in a deal with a supplier to get it at a fixed rate. They also keep an eye on subcontractor costs to make sure those don’t spiral out of control.

3. After Construction: Post-Construction Cost Analysis

Once the building is complete, the estimator’s job still isn’t over. They’ll now compare the estimated costs with the actual costs. This helps figure out if the project went over or under budget, and where money might have been saved or overspent.

Example:

Suppose the project had an estimated budget of INR 5 crores, but the final cost came to INR 4.8 crores. The estimator will go through all the expenses to see where costs were saved. Maybe they were able to get a discount on steel or perhaps there was less labor used because of efficient planning. On the other hand, if the project went over budget, the estimator will identify the reasons—like unexpected design changes or material price hikes.

This post-construction analysis is also important because it helps the construction company understand what to expect for future projects. If there were delays that cost extra money, the estimator will flag this so the company can avoid the same mistakes next time.


At BHADANIS Quantity Surveying and Estimation Training Institute, we’re all about preparing you to become a professional estimator for building construction projects. We focus on giving you practical, hands-on training that’s directly useful in real-life construction situations. Let me explain how we can help you in becoming a skilled estimator and how you can use tools like AutoCAD, Revit, and Excel to manage costs effectively.

1. Understanding the Basics of Estimation 

When you first join BHADANIS, we’ll start by teaching you the basics of estimation—how to break down a construction project and figure out how much everything is going to cost. You’ll learn how to estimate for materials, labor, and other resources, and how to prepare a Bill of Quantities (BOQ).

Example: Let’s say you’re estimating for a 10-storey residential building. In our training, we’ll show you how to calculate the number of bricks, cement, and steel rods required for the foundation, columns, beams, and walls. You’ll learn to analyze the design and then estimate the costs based on the specifications. We’ll help you understand how to get accurate quantities from the drawings so you can avoid overestimating or underestimating.

2. AutoCAD for Estimating Quantities  At BHADANIS, we focus heavily on teaching you how to use AutoCAD for estimation purposes. Most construction drawings come in AutoCAD format, and it’s important for you to be able to measure and take quantities directly from the drawings.Example:If you’re working on a project like a shopping mall, we’ll show you how to use AutoCAD to measure the exact dimensions of each floor, how to calculate the area for tiles or flooring, and how to measure lengths for plumbing or electrical works. This makes your work faster and more accurate because AutoCAD helps you get precise dimensions from the project drawings.

3. Revit for Detailed Project Visualization Revit is another tool we train you on, and this is especially useful when you want to visualize a 3D model of the building. With Revit, you can see the entire structure as a model, which helps you understand the quantities of materials more clearly.

Example: Imagine you’re working on a high-rise office building. By using Revit, you can see the building’s entire structure in 3D, including concrete slabs, walls, and beams. This helps you easily identify how much concrete, reinforcement, or finishing materials will be required for each part of the building. It’s like having a digital walkthrough of the building before construction even begins. We’ll teach you how to use this tool to take accurate quantities and incorporate them into your estimates.

4. Excel for Creating and Managing BOQs One of the most important tools for an estimator is Excel. At BHADANIS, we place a strong emphasis on using Excel for cost management and BOQ preparation. Excel is perfect for calculating, organizing, and presenting all the quantities and costs you’ve gathered.

Example: If you’re working on a multi-storey apartment complex, you’ll need to create a BOQ that lists all the materials required—like cement, steel, windows, doors, and even paints. We’ll show you how to use Excel to input all this data, break it down by category, and calculate the total cost. You’ll also learn how to create formulas in Excel that automatically update costs when market prices change. This makes the estimating process smoother and ensures that you’re always working with the latest cost figures.

5. Real-Life Scenarios and Practice ProjectsAt BHADANIS, we don’t just teach theory. We make sure you’re practicing with real-world examples. You’ll get to work on projects like office towers, residential buildings, or even commercial complexes during your training.

Example: Let’s say you’re tasked with estimating a G+12 apartment building. We’ll give you the full project drawings, and your job will be to use AutoCAD, Revit, and Excel to calculate how much material is needed and prepare a detailed BOQ. We’ll guide you through each step, from reading the drawings to presenting your final cost estimates to a client or project manager.

6. Risk Management and Adjusting Estimates We also teach you how to handle changes in a project and adjust your estimates accordingly. In real life, construction projects always come with surprises—like changes in design or delays in material delivery. At BHADANIS, we’ll teach you how to adjust your estimates when these things happen.

Example: Suppose you’re working on a hotel project, and halfway through construction, the client wants to add a swimming pool. We’ll teach you how to quickly rework the estimate for this additional structure by using the existing AutoCAD drawings to calculate the new material quantities and then updating the costs in Excel. This flexibility is a must-have skill for any professional estimator.
