Location of the Sites

The Petten site is located in the dune area along the North Sea coast. Salt, sand and wind have affect on the buildings. This should be taken into account during contract implementation.

The site is also a nature reserve. Small wild animals such as foxes, rabbits and birds live here under strict protection and conservation (Birds Directive, Nature Conservation Act, and Environment Act). The period from April to the end of August is considered the breeding season for seabirds based on the above mentioned Acts. During this period, the roofs are occupied by nesting birds and any roof activity that disrupts them is strictly prohibited. The autumn period has little influence on the condition of the roofs (few leaves, etc.).

The location of the building in Bergen (called Clubhouse) is approximately 25 kilometers away from Petten. The coast does not have an impact on this building, but the autumn period has a strong influence on it (enrichment of the leaves of surrounding trees). The clubhouse is adjacent to a local sport club with common entrance. The gateway of the area is always locked. There is no guard or staff present, unless an event is organized on the site. The keys to access the building located in Bergen are in the possession of the Infrastructure Group (hereinafter also referred to as ‘INFRa’). In case of any intervention, the keys first shall be collected in advance from INFRA in Petten and afterwards returned back after execution of the work. For the Clubhouse there are no restrictions related to the bird breeding season. Those related inspections and works could be executed any time of the year (in coordination / approval by INFRA), however, in case of certification it is to be ensured that this is performed before the date of the previous certification.
