A Comprehensive Guide for Construction Estimating

Construction estimating is an essential and crucial process in the construction business. Accuracy and precision are the fundamental pillars of a good estimation. Wrong estimations can not help you win projects; in some cases, if they do, such projects end at an incomplete stage due to overrun budgets and mismanagement. Therefore, a precise construction estimation is necessary to complete your projects on time and within the budget. Estimation helps you win the client’s trust, bring more and more clients, and enhance your profit. Estimation procedures have evolved. Initially, construction was done with a ruler and pencil on paper, but with the world’s technological advancements, the estimation process has changed. Many software are available for the construction estimation process. In this blog, we will discuss the construction estimations in detail.

Key Takeaways

What are the Key Elements of Construction Estimating?

Calculating the exact cost for the whole project requires understanding all direct and indirect costs that will affect the project’s overall budget. Calculating all direct and indirect costs helps form an authentic report. The following are the essential elements of estimation for construction projects.

Quantity Takeoff and Prices

The first element that is a must to calculate is the quantity takeoff. Quantity takeoff is a list of all materials and the labor required to complete a project.

Material Costs

Calculating the material cost is also an essential element. A comprehensive market analysis is necessary to determine the recent prices of the materials. Historical data and the cost of materials for the same projects are also used as a sample to determine the estimated cost for the future project.

Hours and Rate of Workers

The cost of the labor. The labor-per-hour rate is the unit used to calculate the total labor cost for the project’s completion. For example, if the labor rate is 5$ per hour and the project needs the labor for 2000 hours, then the total cost of the labor will be 10000$

Tools and Equipment Costs

The cost of the rent for the tools, equipment, and machinery required for the completion of the project is known as the tools and equipment cost and is essential to calculate because it directly impacts the project’s total cost.

Subcontractor Quotes

Building construction consists of many sub-projects, such as mechanical, electrical, and plumbing. These systems are necessary to make the building a worthy place for the people to live. A construction contractor can not do it all alone. He has to get help from the subcontractor’s experts. The subcontractor’s quotes are also an essential element for the estimation report.

Miscellaneous & Indirect Costs

Indirect costs are spending not directly related to the project’s cost but must be included in the estimation report to give precise budget management. These costs cover price fluctuations, administrative fees, transportation costs, any change in worker wages, and changes in the project’s scope.

What are the Types of Construction Estimates

A contractor has to go through various stages during the construction project. He needs an accurate estimation for each stage to complete the whole process. A 100 percent accuracy and precision is possible only when calculating each stage’s cost. Following are the main types of construction estimate

Preliminary Estimates

This estimation is made very early when contractors need to have information about the project. At this stage, estimators use the historical data from the previous projects to calculate the exact cost. For example, if the contractor approaches an estimator to calculate the total cost of building a hospital, then he would estimate by using the historical data for any of his previous hospital project construction estimation, or he would take the idea from other hospitals’ construction costs. Preliminary estimation should be accurate with a slight increase or decrease. This stage estimation is important because the contractor decides whether he will bid for a project or not.

Detailed Estimates

Detailed estimates are the definitive estimates determined based on cost per unit. Then, all these costs per unit are summed up to form a final price for the project. This type of estimate requires all the details and information of the project. Usually, a contractor prepares these bids and proposes them to the owner while the owner hires an estimator to calculate the project’s total cost. If the final estimates match with a bit increase or decrease in prices, they agree to work together. In short, detailed estimates and preparing a base for the bid estimates are very important.

Bid Estimates

Bid estimates are the final estimates for a construction project. At this stage, all materials, equipment, labor, subcontractors, hard costs, and profit margins for the contractors are calculated to give a final winning estimate. The bid estimates should be fair for both parties. It should be profitable for the contractors and acceptable for the owners.

Final Contract Estimates

Final estimates are used to determine the final estimated cost and the scope of the project. In these estimates, material cost, subcontractor cost, equipment cost, labor cost, and any change in the scope of the project are calculated. In short, these are the most detailed and final estimates for a construction project.

Steps in the Estimating Process

According to the Construction Specifier Institute’s (CSI) MasterFormat® divisions, the estimation process should overlook all four steps so that no step or element is missed. The following are the four main steps for the estimation process, which practice the step-by-step construction of the project as the contractors do, ultimately resulting in the most precise estimation.

Understanding Project Plans and Specifications

Do you know that 90% of estimation errors are caused by misconceptions about the project’s scope? Yes, you read it right! Understanding the project’s scope is important before estimating it. There are two ways to do this.

• Thoroughly analyze the initial drawings, plans, and sketches of the projects. They exhibit what the client wants to build. What will be the end product that the client wants, and which type of material and labor expertise are required, which ultimately help to estimate the precise cost for the whole project?
• Visit the site. It helps to determine whether the soil and ground conditions suit the project or if grading and leveling are needed. These must be added to the estimated cost and can affect the project’s overall budget.

Quantity Takeoff Procedures

Quantity takeoff lists all materials, labor, and equipment required to complete the project. Any misinformation in the project can lead to inappropriate and wrong costs, which can cause costly delays or incomplete submissions. An estimator should follow some valuable tips when mentioning quantity takeoffs.

• Always mention the same materials in a group. For example, if you are mentioning wood, mention all types of wood (hard and soft) in the same group. It will help you ensure that nothing is missed. Further, it will be helpful to get discounts when purchasing the wood in bulk from the vendors.
• Digital tools such as CAD are used to create the exact takeoff list. However, traditional tools such as rulers, pencils, and paper can also be used for small projects.
• Always mention the round-up measurement for the materials, which will prevent the contractors from running short. For example, if you require 9.5-yard wood cabinets, always order 10.
• When counting the material, try to remain in systematic order. For example, if you are counting the wood for the windows. Start from the upper right corner in the right and then eventually move toward the upper left corner.

Determining Unit Costs

Once you have completed the materials takeoff, calculate the cost for each material. The unit cost calculations are considered more accurate and perfect. For example, if you want to calculate the cost of the tiles used in the project. Calculate the cost of the tiles per square foot, then multiply this cost with the total square foot of the room. Similarly, calculate the cost for the second room, third room, etc. In the end, sum up all the costs to determine the final estimated cost for all tiles used to complete the project.

Compiling Costs into a Total Estimate

You can calculate the cost for all materials using the unit cost estimating method. Perform a deep market analysis to determine the trending labor cost and rents for machinery, equipment, and tools. Sum up all the costs to give the contractor a final estimate.

Tools and Technology in Estimating

The estimation in construction is revolutionizing with the help of various tools and technologies. Traditional tools for construction estimates were scales, pencils, and paper, and all estimations were done by hand. Over time, the world became more advanced, and technology overlapped each field. Nowadays, various desktop and cloud-based systems are available for estimation procedures, which make the estimations human error-free.
