Unlocking Efficiency: The Overlooked Potential of Parametric Estimating in Civil Engineering and the Construction Industry.

Parametric estimating is a cost-estimating technique that uses historical data and statistical relationships to develop models that can be used to estimate future costs.

It is a valuable tool for construction companies, as it can help improve the accuracy of cost estimates, reduce the risk of cost overruns, and make better project scheduling and budgeting decisions.

However, parametric estimating has challenges. One of the biggest challenges is the lack of data. In the construction industry, data is often incomplete or inaccurate. This can lead to inaccurate estimates and make parametric estimating less reliable.

Another challenge is the complexity of parametric estimating. It can be a complex and time-consuming technique to implement. This can be a barrier for smaller construction companies that need more resources to invest in parametric estimating software or train their staff.

Finally, the construction industry is traditionally resistant to change. Many construction professionals are unfamiliar with parametric estimating and may be reluctant to adopt it.

There are a few reasons why parametric estimating is neglected by the construction industry, especially in civil engineering:

  • Lack of data: Parametric estimating relies on historical data to develop models that can be used to estimate future costs. However, in the construction industry, data is often incomplete or inaccurate. This can lead to inaccurate estimates and make parametric estimating less reliable.

For example, a construction company may not have accurate data on the cost of materials or labour in a particular region. This can make it challenging to develop accurate parametric models for projects in that region. Additionally, the construction industry is constantly changing, so historical data may need to be more accurate for new projects.

  • Complexity: Parametric estimating can be complex and time-consuming to implement. This can be a barrier for smaller construction companies that need more resources to invest in parametric estimating software or to train their staff on how to use it.

Parametric estimating requires a good understanding of the construction process and the ability to collect and analyse data. It can also be time-consuming to develop and maintain parametric models. This can challenge smaller construction companies that may need more resources to invest in parametric estimating.

  • Resistance to change: The construction industry is traditionally resistant to change. Many construction professionals are unfamiliar with parametric estimating and may be reluctant to adopt it.

Parametric estimating is a relatively new technique, and convincing construction professionals to change their ways can be challenging. Some construction professionals also believe that parametric estimating is unnecessary for their projects. They may feel they can get accurate estimates using traditional methods, such as bottom-up estimating.

  • Uncertainty: The construction industry is inherently uncertain. Many factors can affect a project’s cost, such as weather, labour availability, and material prices. This uncertainty can make it challenging to develop accurate parametric estimates.

Parametric estimating is based on historical data, but this data may not be accurate for future projects. Additionally, the construction industry is constantly changing, so new factors may emerge that can affect the cost of a project. This uncertainty can make it difficult to develop accurate parametric estimates.

Despite these challenges, parametric estimating can be a valuable tool for construction companies. It can help improve the accuracy of cost estimates, reduce the risk of cost overruns, and make better project scheduling and budgeting decisions. As the construction industry becomes more data-driven, parametric estimating will likely become more widely adopted.

Despite these challenges, parametric estimating can be a valuable tool for construction companies. As the construction industry becomes more data-driven, parametric estimating will likely become more widely adopted.

Here are some additional thoughts on the future of parametric estimating in the construction industry:

  • As the construction industry becomes more data-driven, parametric estimating will likely become more widely adopted.
  • Developing better parametric estimating software and tools will make it easier for construction companies to implement parametric estimating.
  • The construction industry is becoming more collaborative, making sharing data and developing parametric models easier.
  • As construction professionals become more familiar with parametric estimating, they will be more likely to adopt it.

Overall, parametric estimating is a promising cost-estimating technique that has the potential to improve the accuracy of cost estimates and reduce the risk of cost overruns in the construction industry. As the industry becomes more data-driven and collaborative, parametric estimating will likely become more widely adopted.
