Separation plant for AEB Amsterdam
In a short period of time, Witteveen+Bos drew up a contract document that enabled waste-to-energy company AEB Amsterdam to effectively market its separation plant. For this purpose, various operational principles were verified at AEB and subsequently translated into contractual requirements. Key considerations included financing issues and policy choices concerning waste processing made by the City of Amsterdam and its partner municipalities.
In the first phase of the project (April – October 2015), the operational principles of the separation plant were verified, adjusted where necessary, and subsequently incorporated into the contract documents. In parallel to this process, Witteveen+Bos prepared a reference design so that detailed investment calculations could be performed (for the purpose of obtaining approval for the loan) and permit applications could be submitted.
In the second phase of the project (November 2015 – June 2016), the tender procedure was started (Design & Construct contract compliant with the Uniform Administrative Conditions for Integrated Contracts (UAV-GC)). The designs submitted by the tenderers were assessed for quality and price in multiple rounds. Contract negotiations were conducted with the successful tenderer and a contract was concluded. In the period from September to November 2016, the contractor prepared a design for performance of the work. The design was then checked for compliance with the applicable quality requirements and the agreements reached during the contract negotiations. Construction work began in January 2017 and was completed in late 2017.
By making a reference design, the investment costs were better mapped out and it was possible to start the permit process earlier
