AI can build faster. Can we make decisions faster?

The biggest time savings in construction may no longer be found on the job site, but rather in the years before the first pile is driven into the ground. Digitization can drastically shorten that period. The only question is whether humans can keep up with that pace.

Robots, prefabrication, modular construction, and increasingly smart machines: construction sites have changed significantly in recent years. But before that modern construction site even comes into the picture, a housing project has often already come a long way. From initial planning to completion, a housing project in the Netherlands takes an average of ten years. Time can be saved especially during the planning and decision-making phases.

The Next Wave of Digitalization

With AI, for example, developers can assess feasibility and risks at an early stage. Digital area models make it possible to compare scenarios for housing, mobility, energy, and public spaces side by side. Designs can be directly linked to material data and costs. And as regulations become increasingly digitized and accessible, automated compliance checks are also becoming a reality.

That’s no small gain. The government believes that innovation, digitization, and standardization can help reduce the lead time for design and permitting from eight to four years. According to the government, parallel planning has also demonstrated the potential to save several years in pilot projects.

This is supported by the Act on Strengthening the Management of Public Housing, which has been in effect since July 1. This law requires the national government, provinces, and municipalities to develop a so-called public housing program that specifies how many units will be built, where they will be located, and for which target groups—such as seniors and students. Municipalities make agreements on this within their housing construction regions. Provinces ensure that municipalities have sufficient building sites. If municipalities or provinces cannot reach an agreement among themselves, the province or the national government can ultimately make the final decision.

Speed and Trust

Yet that is precisely the paradox. Because a digital model can calculate different scenarios in seconds, but it doesn’t make political decisions. AI can flag when a design conflicts with regulations, but it doesn’t determine which societal interest takes precedence. And an algorithm can propose a financially optimal neighborhood, but it can’t decide whether local residents actually want that neighborhood. So: technology speeds up the flow of information. People still have to make the choices.

The New Bottleneck

This means humans are in danger of becoming the new bottleneck. Not because government officials, builders, or developers are unwilling to change, but because the construction industry is a chain in which municipalities, consultants, designers, developers, utility companies, and citizens all have interests, responsibilities, and risks. Digitization only truly works when they share data, accept standards, and trust that others are working with the same information.

The government is also struggling with this. The Digital System for the Environment Act is still undergoing continuous improvement; during end-to-end testing, issues such as connections between local software and national systems remained a point of concern. Even the digital permit check has not yet proven to be straightforward for users due to complex questions and technical language.

And there is an even more fundamental objection to the idea that technology solves everything. Not every year of preparation is a waste. Developing an area means balancing interests related to quality of life, nature, infrastructure, affordability, safety, and public support. As early as 2011, the PBL warned that regulations account for only part of the long lead time. The real challenge lies in continually reconciling design, program, finances, and societal interests.

The choice, therefore, is not between building carefully or quickly. The challenge is to become more careful more quickly.

If that doesn’t work out, the contrast will only grow: homes will soon be rolling off factory lines in a matter of months, while we’ll still need years to decide where to put them.

In that case, it’s not construction technology that’s holding back construction output. It’s us.
