Rijkswaterstaat Implements New Environmental Cost Evaluation Method
Utrecht, Thursday, 27 June 2024.
Rijkswaterstaat, the Dutch water management agency, has adopted a new approach to assess environmental costs in projects. This method, implemented since May 27, 2024, aims to enhance sustainability in tenders. The first projects using this standard are expected to be announced on TenderNed before summer.
Innovative Methodology for Environmental Cost Evaluation
Rijkswaterstaat’s new environmental cost evaluation method signifies a major shift in how sustainability is integrated into large-scale infrastructure projects. The methodology centers around the MilieuKostenIndicator-Waardering (MKI-W), which assigns a value to environmental costs and incorporates these into the overall project budget. The aim is to incentivize companies to propose more sustainable solutions by factoring in environmental costs directly into the tendering process.
A Historic Pilot Program
This new approach follows a successful pilot involving 12 projects, where environmental costs were multiplied by a valuation factor and added to the bidding sum. This pilot demonstrated that lower environmental costs could lead to more competitive bids, thereby encouraging sustainability. With the introduction of the MKI-W, bidders now have more flexibility to present the most environmentally sustainable offers, ultimately driving down the environmental impact of infrastructure projects.
Collaborative Innovations in Environmental Sustainability
This initiative is part of a broader trend in the Netherlands towards innovative solutions to environmental challenges. For example, ProRail and Rijkswaterstaat have been exploring 3D printed shot-earth noise barriers. Proposed by Terrestrial and Summum Engineering, these barriers significantly reduce environmental impact, with life cycle assessments showing they account for only 11% of the environmental impact compared to conventional materials. Field tests conducted at the Living Lab InnovA58, a test environment managed by Rijkswaterstaat, have validated their effectiveness.
The Role of Collaborative Platforms
Collaborative platforms like the Living Lab InnovA58 have been crucial in accelerating the development and implementation of these sustainable solutions. By bringing together government bodies, knowledge institutions, and private companies, these platforms foster an environment of innovation and practical problem-solving. Manne Friman, Senior Acoustician Community Noise at Efterklang, emphasized the importance of such collaborations in advancing noise mitigation technologies and other environmental innovations.
Future Projects and Impact
Looking ahead, the impact of these innovations on noise reduction and environmental sustainability is significant. ProRail plans to install approximately 62 kilometers of noise barriers as part of their Long-Term Noise Remediation Programme. These barriers are expected to substantially lower CO2 emissions, addressing both noise pollution and climate change. Additionally, the project underscores the importance of integrating environmental considerations into infrastructure development, aligning with broader EU goals such as the Zero Pollution Plan for 2050.
Conclusion
Rijkswaterstaat’s new methodology for evaluating environmental costs in projects is a pioneering step towards more sustainable infrastructure development. By integrating environmental costs into the tendering process and fostering innovation through collaborative platforms, the Netherlands is setting a benchmark for other countries to follow. The forthcoming projects announced on TenderNed will be a testament to the effectiveness of this new approach, promising a more sustainable future.
