The assignment concerned investigating and planning the carrying out of land reclamation before the coast of St. Petersburg. The only option for expanding this metropolis’ city centre was through land reclamation, only the Russians have little experience with these kinds of projects. Therefore, Dutch specialists have been set to work.
Project information
Vasilievsky Island is part of the historic city centre of Saint Petersburg, Russia. The tri-angular shaped island is surrounded by two branches of the Neva river and its western shoreline borders the Nevsky Bay. At short distance from this shore, Morskoy Facad, a Russian managing company, is developing a land reclamation bordering Vaisilievsky Island that is intended to accommodate further urban expansion and modern facilities to receive cruise vessels and their passengers.
The overall development schedule for the works distinguishes three phases which are sub-divided in several reclamation areas (477 hectares in total). Until the year 2012 these areas will be reclaimed one after another, which allows for a gradual construction of the buildings and development of the island infrastructure.
Description of project
In 2006 Witteveen+Bos was involved in phase 1 of the project. Mid 2007 a new contract was signed with Lenmorniiproekt (LMP), a renowned Russian engineering company. Together with LMP the dredging- and reclamation concepts were generated and evaluated and subsequently the design- and tender documents inclusive of a construction cost estimate for the next two development phases (350 ha) were prepared. Furthermore, the consultants were responsible for obtaining the design approvals from the authorities. The first documents will be used for the construction works in the year 2008.The input of Witteveen+Bos concentrated on the development of the reclamation, coastal and hydraulic concepts as well as on the geotechnical aspects. The project site is situated in the Neva river delta and the subsoil is generally rather soft. With the use of the experiences of the phase 1 construction and on the basis of newly obtained soil data, the anticipated settlements have been determined including consolidation accelerating measures. Subsequently the required sand volumes were estimated. Furthermore, Witteveen+Bos advised on the required compaction works, groundwater management, the construction schedule and the construction management plan.
The combination of LMP and Witteveen+Bos offers a joint knowledge and experience which attrib-utes to a successful preparatory stage. It will surely form the basis for lasting co-operation between LMP and Witteveen+Bos in future projects.
