The Start Date Doesn’t Move – Paulien Neppelenbroek (De Bouwdirigent)
Structuring decision-making to enable smart design
Different techniques have been developed for foundation re-use and foundation restoration with reduced carbon footprint. The real challenge? Getting them implemented. When cost and schedule pressures increase in projects, we tend to revert to conventional solutions. Simpler designs feel safer because they help us stay on schedule and within budget more easily.
During the Conference on Foundation Decarbonization and Reuse, Paulien Neppelenbroek shared her perspective on why we should stop simply replacing foundations and start exploring smarter alternatives. In this webinar, she takes the next step: how to actually make those alternatives happen, without losing control over the schedule. By structuring decision-making throughout the design process, projects stay on track even when innovative approaches are introduced. The key principle in these projects is simple: whatever the challenge, the construction start date of is fixed.
This is how innovative design ideas turn into feasible projects, by organizing the decision process in a way that makes them actionable. Instead of innovation being blocked by complexity, it becomes something that can actually be delivered.
By sticking to the start date of construction, a clear framework is created in which smarter solutions like foundation reuse and low-CO₂ strategies can truly be explored, tested and realized.
What started with her own foundation project in 2022 is now applied more broadly: a way of working where the focus on schedule and cost does not limit innovation, but actively enables it
and makes it happen.

On Tuesday, February 3, 2026, a webinar was held on the challenges of timber pile foundations in historic urban areas, with a focus on Boston and its surroundings.
The session explained how many 19th- and early 20th-century buildings in Boston were constructed on untreated timber piles, designed to remain permanently submerged in groundwater. Over time, groundwater levels declined due to urban developments such as sewer systems and dewatering, exposing the piles to decay and creating risks for these historic structures.
It was highlighted that, since the 1980s, the City of Boston has taken measures to stabilize and restore groundwater levels. However, many timber piles remain insufficiently submerged, posing ongoing challenges for maintenance, reuse, and expansion projects.
The webinar provided practical insights into evaluating timber pile foundations, including assessing their condition and capacity, identifying common pitfalls, and balancing investigation efforts with project risks and client priorities.
The session was presented by Nathan Davis (McPhail Associates), who shared his expertise on this complex geotechnical issue.
Recording webinar February 3
Date: Tuesday December 9, 2025
Time: 15.00 CET, 9.00 (EST).
As part of the Foundation Decarbonization and Reuse series, the webinar held on December 9, 2025, was titled “Load Testing for Foundation Reuse.” The session demonstrated how thoughtful foundation design can significantly contribute to reducing the carbon footprint of construction projects.
During the webinar, Marcel Bielefeld of Allnamics outlined strategies to reduce both carbon emissions and material consumption in foundation design. Foundations and basements can account for 30% to 60% of a building’s total environmental impact. Given that each cubic meter of concrete contains more than 2,000 kg of raw materials, even modest reductions in concrete volume through smarter foundation solutions can lead to substantial environmental benefits.
The webinar emphasized intelligent foundation design by making more effective use of existing safety margins and encouraging the reuse and life-extension of existing foundations. Pile load testing was presented as a key tool for determining the actual as-built pile capacity, reducing uncertainty, and optimizing allowable loads.
Through practical case studies, the presentation illustrated how load testing enables more efficient foundation reuse, supporting a more sustainable, material-efficient construction industry.

Time: 15.00 CET, 9.00 (EST).
On 7 October, an engaging webinar took place focusing on an innovative project in Ontario, Canada, for the Ministry of Transportation (MTO). The session explored the potential for reusing existing steel piles as part of a bridge rehabilitation and replacement project.
Representatives from both MTO and WSP shared their approach to evaluating the feasibility of pile reuse. Through an extensive desk study, WSP assessed all relevant aspects to determine whether the existing piles could be reused, and if so, whether they would need to be supplemented to support the new superstructure.
Speakers Tony Sangiuliano (MTO), Lisa Coyne (WSP), and Riley Shuster (WSP) provided valuable insights into the decision-making process, technical considerations, and lessons learned from this study.
The discussion offered participants a practical example of how existing foundations can be assessed and potentially reused, contributing to more sustainable and cost-efficient infrastructure solutions.

The next edition of the International Conference on Foundation Decarbonization and Reuse, which is scheduled to be organized in March 2026, featured a new event: a workshop on software tools designed to help users minimize the carbon footprint of foundations and assess options for reusing existing foundations. This webinar focused on the requirements that made software a useful tool in that endeavor.
To assist with decarbonization, the key requirement was straightforward: the software needed to be able to define the foundation with the smallest carbon footprint. For reuse, however, defining the requirements was not as simple. Obviously, the software had to recalculate the bearing capacity of the foundation as designed. But should it also have generated options to supplement existing foundations if that bearing capacity was inadequate? Or should it merely have detailed user-defined options? During the webinar, Gerald Verbeek explored these issues with Thomas Zwaenepoel, Christopher Nelsen, and Jacco Haasnoot.

Time: 15.00 CET, 9.00 (EST).
Speakers:
Tony Sangiuliano (Ministry of Transportation of Ontario Canada)
Andrew Boeckmann (Dan Brown and Associates)
In this webinar, Tony Sangiuliano presented the Reuse of existing steel pile foundation study-hallecks RD and HWY 401 bridge, Brockville, Ontario, Canada. The Ministry of Transportation Ontario is exploring the reuse of existing piles to enhance traffic mobility, economic efficiency, sustainability, and environmental benefits.
Additionally, Andrew Boeckmann (Dan Brown and Associates) gave a presentation about Foundation Reuse in the U.S.: Impediments and Opportunities. Foundation reuse is gaining attention in the United States as aging infrastructure and physical constraints drive the need for innovative solutions.

Natalia Rucinska (Menard)
In this webinar, Jessica Oudhof from ARUP presented the idea of reusing existing foundations under key bridges in the Netherlands when they are replaced to meet current demands.
Additionally, Natalia Rucinska from Menard discussed how to navigate stakeholder concerns regarding foundation decarbonization and reuse.
