General planning and construction services for public sector clients
Shaping a sustainable and participatory future – efficient, reliable, and fully compliant.
Managing public construction projects safely, cost-effectively, and in full regulatory compliance
We enable public project owners to make well-informed, sound decisions – from initial needs assessment through planning and procurement to implementation and commissioning.
With clear criteria, reliable cost and schedule forecasts, and dedicated project teams, we provide guidance and deliver effective, user-focused, and sustainable solutions.
Solution-oriented and procurement-focused
With over 30 years of project management experience and deep methodological expertise, Vollack stands for reliable delivery and forward-thinking solutions.
We turn user needs into viable, future-ready concepts. Architecture, technology, and organization work seamlessly together under one roof.
The result: the right balance of quality, cost, and schedule.
Our portfolio of certified, energy-efficient, and award-winning projects proves our ability to deliver solutions that meet even the most demanding requirements.
Efficient planning –
sustainable construction
Public construction projects are becoming increasingly complex: transformation pressures, demographic change, and the integration of stakeholders and processes all demand smarter solutions.
With forward-thinking planning, risks such as cost overruns, delays, and poor user experience are minimized from the start. A holistic approach lays the foundation for sustainable, future-ready buildings.
Design + Build: one partner, one point of contact. We guide every phase, ensure seamless coordination, and maximize the long-term value of your investment.
Because buildings can deliver more than expected – when they are planned with foresight, costed reliably, and built sustainably.
Planning and building for the future
of the public sector
Vollack supports public sector clients and their construction projects from the very beginning – delivering expert solutions and methodological precision right from the initial planning phase.
In the NULL® phase, we analyze needs, usage requirements, and organizational structures to design flexible, adaptable spaces for evolving work environments in public administration – and to create an optimal user experience.
With creativity, respect, and reliability, we develop fully implementable concepts that connect stakeholders, support public processes, benefit citizens, and secure long-term investment value – even in a constantly changing environment.
Experience the NULL® phase for your project. Each agenda is tailored to your specific needs – because we don’t believe in off-the-shelf solutions.
We have been working with BIM (Building Information Modeling) for many years and actively share our expertise with universities. We are convinced that collaborative design and construction deliver the greatest value for our clients.
