What looks cheap today may turn out to be expensive tomorrow

A competitive cost estimate is important, but the lowest purchase price is rarely the same as the lowest total cost. For the building owner, a sustainable investment involves understanding which factors affect the project’s finances even after the building has been put into use. Cost estimates are often based on assumptions about material costs, standard solutions, and construction methods. It is only when the project is carried out—or several years later—that the difference between a low purchase price and a long-term, reliable solution becomes clear.

Additions, redesigns, maintenance, documentation gaps, or materials that do not meet the project’s requirements can result in costs that far exceed the initial savings. Therefore, the choice of materials should always be evaluated based on verified functionality, documented performance, and long-term management, not solely on the purchase price.

A well-founded cost estimate not only provides financial security—it also reduces the risk of unexpected costs, delays, and future liabilities.

What Looks Right on Paper—But Not in Reality

A cost estimate is only as good as the assumptions on which it is based.

In a traditional project estimate, it’s easy to compare items that are directly measurable—such as purchase price, material consumption, and contractor costs. It is considerably more difficult to estimate costs that may arise later, such as those resulting from scope changes, delays, design revisions, increased maintenance, or inadequate documentation.

It is often these factors that determine the actual cost of the project.


  • 1Material Cost
    The lowest purchase price is not always the lowest total cost. A sustainable cost estimate should also take into account documented performance, service life, maintenance, project risk, and costs that may arise during the building’s operation.
  • 2Installation
    Efficient installation contributes to a safe and cost-effective construction process. At the same time, it is important that the material be verified for the specific structure and the operating environment in which it will function throughout the building’s service life.
  • 3Delivery
    Reliable delivery involves more than just sticking to the schedule. For the developer, it is crucial that the right materials are delivered, with the correct documentation and in accordance with the project’s technical requirements.
  • 4Schedule
    A well-planned schedule leaves little room for last-minute changes. By ensuring that the right materials and documentation are in place from the start, you reduce the risk of delays, additional work, and increased project costs.
  • 5Long-Term Performance
    It is not enough for the material to meet the requirements at the time of delivery. For many applications, it is crucial that the documented performance is verified to endure over time, despite the effects of use, moisture, climate, and natural aging.
  • 6Long-Term Performance
    It is not only the material’s properties at the time of delivery that are important. If its function or performance changes over time, this can affect maintenance needs, liability issues, and long-term management—costs that are rarely factored into the initial estimate.
  • 7Subsequent Remediation Costs
    Additions, renovations, and corrective measures can be costly, disrupt operations, and result in additional expenses long after the project has been completed.
     
  • 8This is where the true cost analysis is determined
    Once the project is completed, the consequences of the choices made become clear. A sustainable cost estimate should not only work at the start of the project—it should also hold up once the building is put into use, managed, and reviewed over time.

This is where the calculations begin to differ.

When the estimate seems too good to be true

A quote may look attractive on paper—with a low price, short delivery time, and requirements that appear to be met. But a sustainable investment isn’t just about what fits within the budget; it’s also about understanding what’s actually included and how the solution has been verified.

When the price or delivery time differs significantly between different options, there are often underlying differences. These may relate to documented performance, testing, certification, traceability, quality control, or the product’s long-term functionality. These are factors that may not be apparent in the initial cost estimate but can have a major impact over the building’s lifespan. Therefore, what appears most advantageous during the procurement process is not always the solution that results in the lowest total cost over time.

A well-founded cost estimate is based on documented functionality, verified performance, and a clear understanding of the project’s long-term risks and management needs. That is where a sound investment begins—and where many costly surprises can be avoided.
