A well-functioning regional association is ensured by the board of directors and the management, supported by numerous members - who work on a voluntary basis in addition to their planning and entrepreneurial activities. They form the basis for representing the profession vis-à-vis politics, administration, business and private clients. Thus, the bdla regional group of Lower Saxony and Bremen repeatedly takes a stand on amendments to the law or guidelines. Active advocacy for appropriate remuneration and handling of award procedures is also part of the range of tasks.

In order to do justice to the diverse tasks in urban, object, landscape and environmental planning, the bdla offers a comprehensive, thematically broad range of specialist and further training events. The offer ranges from questions of building technology to environmental and nature conservation law topics to the topics of building culture, garden art and open space design. For example, bdla N+B has dedicated events to topics as diverse as the methods laboratory participation or the use of open source GIS.

A major concern of the state association is the promotion of young professionals. The series on the use of materials, which has been held very successfully since 2017, is intended to provide young planners with compact information on professional technical application and design possibilities. The event gains a special appeal through practical reports from offices with time for a professional discussion and this in an 'after-work format'.

Young talent competitions, construction site summer and workshop reports from the offices always provide platforms for young talent.
