Thursday March 23

The site visits are scheduled on the third day of the Conference on Decarbonization and Re-use: a day to meet the industry, visit projects, and meet and speak to like-minded engineering colleagues in the working field of the sustainable construction industry.

During the site visit, several sites and projects in and around Amsterdam will be visited to give an impression of the possibilities of reducing decarbonization by re-using existing foundations. The program offers several tours, each with its own focus and the participants can select one tour in the morning and another in the afternoon, with a lunch served between the two tours.

Tour 1 (8.00-12.45)

This tour will visit finished projects, where existing buildings have given a new function to highlight how architects, owners, structural engineers, contractors and foundation engineers have worked together to make sustainability more than just an ambition. The tour visits a revived building reconstructed from four individual buildings, originally constructed in the 1970s. The result is an energy-efficient building with the BREEAM Outstanding status. The tour will also visit an old prison that has been converted into a multi-purpose center, including a cinema. An old prisoner will explain what has been done to the building to make it suitable for its new functions. Travel to these buildings will be by a sustainable touring car.

Tour 2 (8.45 – 12.00)

This tour is a walking tour along finished and ongoing projects in downtown Amsterdam where foundations have been or are re-used. This often requires extensive investigations to assess the suitability of the existing, and often old, foundations for future use, in many cases supplemented by additional foundation works to guarantee that future use. Old historic buildings with old, new and mixed foundations will be visited. And, if the construction schedule is cooperating, a building pit where an existing foundation is examined will be part of the guided walking tour.

Tour 3 (13.00 – 17.00)

Meet the industry parties of sustainable concrete mixes and concrete products. Most of the concrete in The Netherlands is based on the principle of cradle-to-cradle. New developments in breaking down concrete to its basic components make it possible to increase the applications of reused concrete. The tour visits a plant where concrete waste is broken down into aggregates and cement and a production plant of precast concrete foundation elements. The production process of these elements, as well the sustainability philosophy of a cradle-to-cradle foundation will be shown.

Tour 4 (13.15 – 16.00)

Amsterdam is in the process of renewing their quays and bridges throughout the city. Most of the 1000 bridges of downtown Amsterdam were designed centuries ago for the traffic loads at that time, i.e. the maximum load of a lorry pulled by hand or horse. Nowadays traffic is obviously heavier and more intense. And the bridges are still there, despite their age.  But apart from the bridges, the hundreds of kilometres of quays along the canals were also built centuries ago. Replacing them is unnecessary when re-use is the standard. What is the status of the public works on the world-famous bridges and canals of the center of Amsterdam? There will be presentations in the downtown visitors and exposition center, about how Amsterdam has developed over the centuries and the role of the canals, followed by a guided walking tour where the investigation, monitoring and restoration works can be observed.
