How to Calculate Construction Costs

If you are in the process of planning a building project, you may want to calculate the construction costs in advance. You can use construction cost indices to help you. Inflation is one factor that affects the cost of construction. However, it is not the only factor. You will also need to consider the component costs of construction.

Inflation of construction costs

While construction costs continue to rise, the rate of inflation remains relatively low. According to Construction Analytics, the average annual rate of inflation for residential construction was 3.4% in 2017. The inflation rate for non-residential buildings averaged 4.4% from 2011 to 2020 and dropped to 2.5% in 2020. In contrast, the average annual rate of inflation for residential buildings jumped to 9.1% by 2021, and it is projected to rise to 15.4% by 2022.

This inflationary trend has a number of consequences for the construction industry. First, it drives up the cost of materials, which is often about 35% of the total construction cost. This causes construction firms to lose business when they cannot keep up with the rising cost of materials. Further, it can make the process of securing funding more difficult. Funders will often be more cautious when evaluating projects that are high value, complex, or take long to complete.

A decrease in volume should help ease inflation in the next few years, as firms compete for fewer new projects. However, it will increase labor costs as productivity declines. Inflation also increases the cost of materials. As a result, real construction volume is forecast to increase just 1.1% in 2021. This is not an ideal situation.

The rate of inflation in the construction industry has increased significantly since March 2020. This is due to escalating costs for energy and materials. This has led to higher prices for machinery, transportation, and technology. For example, the cost of crude oil increased by 75.2% from 2021 to 2022. Higher energy prices mean higher transportation and rental costs for construction machinery.

Components of construction costs

When calculating construction costs, you need to know how the three main components affect the overall costs. The first two components are labor and materials. Overhead and profit are also important components of construction costs. Both components are influenced by the economy, and each behaves differently depending on the market cycle. If you’re looking for a construction contractor in your area, be sure to ask about their profit margins.

One of the most crucial components of construction costs is the price of raw materials. Materials are essential to the construction process, and prices have increased by 0.8% in September. The Producer Price Index, which measures inflation across all goods and services, includes many different items that are consumed during the construction process. However, some materials have been impacted by price declines, such as asphalt and copper.

Construction materials are the most vulnerable to changes in the global market. It is therefore necessary to take into account both local and global markets when forecasting material cost. Additionally, building code requirements can influence the cost of materials specified for construction. An experienced construction cost estimator will often have access to data sources to determine the best materials to use.

Building codes are continually changing to make buildings safer. While these changes can impact material costs, they can also increase the number of components that must be used in a construction project. In California, for example, updates to CalGreen and Title 24 Section 6 have increased the complexity of building envelopes, HVAC, and electrical systems. This means that more components must be installed and inspected, which increases the cost.

Sources of construction cost indices

Cost indices are used by construction professionals to estimate the costs of construction projects. The methodology of these indices varies, but they are usually based on the cost of inputs and not the price of outputs. Understanding how these indices are calculated will help you interpret the results.

Construction cost indices come from several sources. The Engineering News-Record (ENR) publishes a construction and building cost index. These indices measure the effects of changes in labor, materials, and wages. They are unadjusted for changes in technological advances and productivity. Handy-Whitman Utilities also publishes building and construction output indices.

Construction cost indices are often based on a composite of major building sectors, or may be based on final costs of individual building types. In addition to building type, construction cost indices may be based on input prices or producer prices. Depending on the source, these indices may over or undershoot inflation. In addition to these general price indices, construction cost indices may include indices based on specific input factors such as Building Trades Union Wages or wholesale Building Material Prices.

The construction material cost index tracks the dynamics of producer prices in the domestic market and includes 43 different product groups. It also includes activity classes in sections B – Mining and quarrying and C – Manufacturing. The labour cost index, on the other hand, reflects the costs of an hour of labour in construction. These cost indices are calculated from weighted data sources in the final accounts of companies in sections F and G – Construction.

Nonresidential buildings have experienced a significant increase in prices over the past few years. In 2018, the rate of nonresidential building inflation was 5%, while the building cost index for nonresidential construction rose by an average of 4.5% over the past four years. The latest figures published by Engineering News-Record show that the construction market for dwellings will experience inflationary headwinds throughout the first half of the year. For the second quarter of 2022, the Mortenson Cost Index indicates that building costs will rise by 3.3% nationwide and 2.6% in Phoenix.

Estimating construction costs

Estimating construction costs is an essential part of a construction project. The process begins with a pre-design phase, where the contractor gathers information to determine the project’s scope, functions, materials, and costs. Then, the contractor breaks down the costs into direct and indirect costs, including markups, costs for materials, labor, and transport. Estimating construction costs also requires consideration of profit, which is the percentage that the construction company adds to the total cost of the project.

Construction cost estimates are essential to tracking the construction process, value engineering, and project management. These estimates will compare completed work to planned and budgeted costs to determine whether the project is under or over budget. By comparing the scope of the completed work with planned costs, the project manager can make informed decisions about how to spend the money. If the estimated costs are higher than planned, the project is either ahead of schedule or over budget.

Labor costs account for roughly half of a construction project. Third-party databases often use general labor productivity figures, but you should adjust for specific labor productivity in your region. Finally, don’t forget to adjust for the productivity of your company or subcontractors. A good rule of thumb is to estimate labor hours based on the scope of the project and adjust for a ten percent safety margin.

While it’s possible to revise a preliminary estimate later, it is best to start your cost estimation process early. Without accurate cost estimates, you can’t provide an accurate quote to your contractor or accept a winning bid. Without a clear picture of the costs, you won’t know whether or not the project will be too expensive or whether or not you’ll be able to turn a profit. Estimating construction costs is essential to the success of any construction project.

Impact of construction costs on price of housing

Construction costs can affect the price of housing in several ways. These costs can be high or low, and they also vary greatly between markets. For example, labor costs in New York City are 31 percent higher than the national average, while labour costs in Chicago and San Francisco are nearly 16 percent higher. Construction costs are also higher in densely populated cities, such as Chicago, Los Angeles, and New York. Consequently, the construction cost for new homes in these cities may be higher than the national average.

Construction costs are rising, and the housing industry is feeling the pinch. The shortage of labour in many areas is contributing to the price hikes, especially in high-demand housing markets. The shortage of construction workers has increased costs in many trades, including crane operators, elevator constructors, mechanics, and others.

Another contributing factor is the cost of land. As the cost of land rises, construction costs will increase, too. According to Altus Group, the cost of land for high-density residential developments in Vancouver ranges from below $100 per square foot to more than $300 per square foot.

In addition to construction costs, local land use regulations can also affect housing prices. In Los Angeles, for example, stricter building regulations have increased construction costs by 10.8 percent. Although these regulations are designed to protect the public, they often cause a large price increase in new houses. Furthermore, these regulations can impact prices by limiting land use and restricting supply.

Recent research suggests that persistently high construction costs may be contributing to the housing market’s current slump. Although the price of new homes has recently risen above its peak in 2006, recent mortgage borrowing has been subdued, and expectations of further house price gains remain tempered. These factors could make construction costs a bigger factor in the current price trend than credit conditions and expectations for future growth.
