INSTRUCTIONS REGARDING THE COMPETITION SITE The entrants should make their designs broadly compliant with the requirements in the the City Masterplan that are listed (translated into English, on the following page). In addition, the following information regarding the competition site groundwork should be considered: The real-life situation: The Verkkosaari area and the competition site has challenging groundwork conditions. The reason is that the area will be built on former industrial infill land, which contains contaminated soil to varying degrees depending on site location. Construction on the competition site will require careful soil investigations, groundwork planning and procedures for removing any contaminated soil that is found during the investigations and/or construction. In addition, the soil is not load bearing, which requires pole foundations for the buildings. This will lead to a situation where all projects that will be built in the area will have to reserve a significant part of overall project cost and resources for groundwork. While the groundwork conditions are not ideal for affordable construction, the location has other qualities that balances out the holistic setup. Assumptions for the competition: Because the real-life planning and site development challenges are considerable, they are not included in the competition. Entrants should instead follow these instructions, assumptions and considerations regarding the groundwork:

• No spaces may be built under street level • The site is ‘ready-to-build-on’, in other words all required soil investigations

and groundwork planning/construction can be assumed to be complete. • Entrants should focus their designs on what happens on and above street

level, outside and inside of the building(s) • Entrants may present and illustrate the groundwork and foundations of the

building(s) in any schematic way that suits their presentation

The building right includes the areas of floors calculated from the exterior surface of the exterior walls. In addition, it includes basement and attic areas where, due to their location, connectivity, size, lightness and other characteristics, primary use premises of the building are and can be located. If the thickness of the exterior wall is more than 250 mm or the thickness of the apartment partition wall is more than 200 mm, these additional areas are not counted in the building right.

The bottom slabs of the buildings must be built in such a way that it is, if necessary, possible to equip the structures with mechanical ventilation. Possible bottom sediment pollution has to be investigated in areas where the city plan requires dredging or in other areas where significant actions on the bottom sediment are taken. Streets and blocks of the plan area may not be be built before the shoreline structure (pile slab structure and shore wall) between the current and future shorelines of the plan area as well as in the plan area for the floating housing has been completed. In garages there is no need to build plot borders. If the boundary wall is not built, different plots will be considered as a whole in order to secure sufficient level of safety. Parking spaces may be constructed in addition to the marked building right. On the two lowest floors of the buildings there may be commercial and public service premises as well as facilities that serve municipal technology. The plot part between the construction area and the street area must be built to the same elevation and matching surface as the street area bordering it. Stairs and entrance ramps may be built in this area. The surface structure of the main doors must be wood. The roof surfaces must have green roofs and terraces as well utilized for solar panel installations. Metal roofs are allowed on plots 10651/2, 10652/6 and 10656/1-2. The tramway shall be designed in such a way that vibration or body noise caused by the vehicle does not exceed the maximum for what is allowed in indoor spaces.
