Our world is getting more and more complex

Construction tasks continue to get more complex due to project-specific requirements and legal stipulations,. Conventional working methods and control methods in planning and execution are at their limits – all of which is forcing companies to rethink in many areas. The goal: to reduce redundancies and prevent avoidable costs. This rethinking is also opening new avenues for progressive processes and the best possible coordination to encourage the greatest possible project success in planning, construction, and operation. Cutting redundancy is clearly also an imperative for sustainability.

The supreme discipline: thinking BIM and LEAN together

In the construction industry, Building Information Modelling (BIM) stands for the global trend towards digitalization. As part of this evolution, BIM digitally models, records and combines all relevant building data. Safeguarding the client’s decision-making processes early on, for example through solutions like virtual reality (VR), lends further advantages.

Lean Construction (LEAN) describes a management or philosophical approach in the construction industry, which was gleaned from automotive construction; it pursues increased customer value through continuous improvement and eliminating waste in processes.

The linking of BIM and LEAN can be seen as the supreme discipline that harbors a special opportunity for the planning and construction processes of the future.

Benefits for clients

Clients will benefit from BIM and LEAN as a consistent continuation of our methodical approach.

As a rule, direct value is added where waste is minimized or eliminated. Complexity is drastically reduced by clear and transparent work packages in both the planning office and in construction. The flow-oriented dovetailing of planning and execution creates a new kind of cooperation unlike anything in conventional construction.

Studies show that the ideal coordination of processes and workflows in planning and construction makes for an optimization potential of up to 70 percent! Conflicts and technical constraints can be identified and eliminated early on when they are combined with production and factory planning, thus shaping the interface to Industry 4.0. Construction projects receive an enormous boost in terms of costs, quality, and compliance with schedules when they are structured sensibly and supported digitally.

Open and transparent work methods

Vollack consistently relies on lean processes and open BIM. Knowledge and work are shared transparently, and the best architecturally sustainable variant is developed barrier-free together with all planning and construction participants. Data and information are exchanged on an open collaboration platform, based on the Industry Foundation Classes (IFC) – a software- and country-independent data exchange format.

Combination of individual subject models in a coordination model







Through active collaboration, processes are transparently planned and controlled across all specialized disciplines and phases to get closer and closer to the ideal: added value for the customer – with no waste.

Ticket to the BIM and LEAN world

The Institut für Wissenschaftliche Weiterbildung (Institute for Continuing Scientific Education) and the Steinbeis-Transferzentrum für Bau- und Immobilienmanagement (Steinbeis Transfer Center for Construction and Real Estate Management) at Karlsruhe University of Applied Sciences have set up continuing education courses on BIM and LEAN construction for professionals and managers working in the field. The advanced training courses blend scientific quality with practical application in construction. Professors from the Faculty of Architecture and Civil Engineering and experts from the construction industry cooperate in these courses. Vollack – a specialist for methodical planning, construction, and revitalization of sustainable, energy-efficient buildings in office buildings, industry, and health – cooperates as a professional partner and co-initiator.
