Construction of Bioswale with 30-Year Maintenance Contract

The municipality of Den Haag is seeking a contractor for a Design, Build & Maintain project focused on a bioswale. This project encompasses the entire lifecycle, from initial design and construction to a substantial 30-year maintenance period. Key aspects of the maintenance phase include ongoing management of the bioswale, consistent groundwater monitoring, and ensuring adherence to water quality control standards. Contractors should be prepared to demonstrate expertise in these areas. The inclusion of a 30-year maintenance contract suggests a long-term commitment and necessitates a robust operational plan.

Given the Design, Build & Maintain structure and the long maintenance period, this project likely involves a detailed proposal with a strong emphasis on long-term cost-effectiveness and sustainability. The integration of design, construction, and long-term maintenance demands a comprehensive understanding of bioswale functionality and environmental considerations. Contractors should assess their capabilities in environmental monitoring and water quality management, as these elements are explicitly mentioned. The absence of a published deadline or CPV codes necessitates further investigation to ascertain project specifics and determine suitability for bidding.
