New requirements for planners and installers: BIM and building contract law

Professor Dr. Frank Ehrenheim, Department Facility Management, Technische Hochschule Mittelhessen

„How BIM and Security are related“

Buildings are to be built and operated sustainably to make them meet the economic, ecological and social goals demanded by society. This requires an integrated data model that brings together all the interests of the various stakeholders of a building. At the Intersec Forum 2019 of Messe Frankfurt, Prof. Dr. Frank Ehrenheim from the Facility Management Department at the Mittelhesse University of Applied Sciences outlined seven dimensions of Building Information Modeling (BIM).

Along to the 3D model, time and cost planning, it also contains the requirements for sustainability, efficiency and resource saving as well as for facility management for the operation of the building. Strategic obsolescence management is also necessary as part of security and risk management in order to extend the life cycle of a building and reduce operating costs. The consideration of fire protection and security technology in the data model leads to more security and lower costs. Simulations during the planning phase, for example, allow the use of current products even for longer planning periods, foresighted maintenance and automatic checks for compliance with the applicable regulations. A challenge for the future is the use of the extensive data available even after acceptance of the building.

„BIM in security technology: current status from the point of view of a specialsit planner“

Building Information Modeling (BIM) will revolutionize the construction and operation of buildings in the future. But where do we stand today? Can we already apply BIM to safety planning? Markus Groben, Managing Director of Groben Ingenieure, reported at the Intersec Forum 2019 of Messe Frankfurt on a self-experiment from the perspective of a specialist planner.

"BIM is a working method that requires cooperation. It's not 3D CAD planning and you can't just buy it," describes Groben BIM as an overall process. "Digitisation based on inadequate processes and structures does not work." For this reason, it is also necessary for all parties involved to rely on open standards for data formats and interfaces. In practice, however, this is currently not yet given. In Germany, the standard service book and the GAEB interface already provide a solution. According to Groben, however, the provision of open standards should take place quite soon, as otherwise de facto standards of individual software manufacturers would establish themselves.

Georg F. Schneider, Research Associate Fraunhofer Institut für Bauphysik (IBP)

„From `BIM-Reference Object in Germany´ to zum `SME 4.0-competence center Planning and building´“

Architects, specialist planners and installers of security and building technology as well as small companies and craft businesses are already finding comprehensive advice on all aspects of Building Information Modeling (BIM). Georg F. Schneider, a researcher in the Building System Solutions working group at the Fraunhofer Institute for Building Physics IBP in Nuremberg, provided numerous suggestions at the Intersec Forum 2019 of Messe Frankfurt.

The Competence center planning and building for SMEs 4.0 supports the implementation of digitisation and the entry into BIM. The focus is on the entire construction value chain with the four thematic areas of project development, planning, construction and operation. The offerings and services included demonstrators for specific applications, presentations and documentation of best-practice examples, lectures, training courses and various event formats such as BIM breakfasts for the exchange of experience and networking. The "BIMiD - BIM Reference Object in Germany" project, in which the use of BIM was demonstrated exemplarily on the basis of two construction projects, was already completed in 2017.

Jürgen Rumeney, Senior Consultant Security Siemens Building Technologies Deutschland

„Designing security technology for the future in a predictable way“

Building Information Modeling (BIM) will change building in the future. Jürgen Rumeney, Senior Consultant Security at Siemens Building Technologies Germany, explained at the Intersec Forum of Messe Frankfurt how the components of this virtual planning can already be used profitably today.

Virtual media and simulations are key factors for planning the future, especially in security technology. The data available in the "digital twin" of the building can also be used to apply  alarm management, evacuation and human streams plannable in advance and thus increase security in the real building. Previously complex real-time simulations such as the calculation of human streams during an evacuation would be considerably facilitated by the digital twin. According to Rumeney, Virtual Reality (VR) will increasingly be used for planning in the future, enabling, for example, complex sensor areas to be defined in the virtual building and suitable devices to be selected.

Dr. Thomas Rütten, Lawyer and specialist lawyer construction and architectural law Kapellmann and Partner Attorneys

„One year of new building contract law: current and future challenges“

The amendments to the building contract law in force since 1 January 2018 have a direct impact on any type of building project, including safety & security engineering and technical building equipment. Dr. Thomas Rütten, lawyer and specialist lawyer for construction and architectural law at Kapellmann und Partner Attorneys, explained the effects at the Intersec Forum of Messe Frankfurt using the example of ordinance law.

Under the new law, agreement is to be reached with the contractor in the event of changes to the client's orders. The previous drafting of contracts was not compatible with this objective. The contracts would therefore have to be redesigned, for example with differentiating and cooperative regulations, in order to guarantee the success of the project for all parties involved. "The new building contract law has a positive effect, also for the safety & security engineering and building services. New, differentiated or multi-party contracts create transparency and a climate of participation and reward concepts in (construction) practice," Rütten concluded.

Q & A session with the speakers on "New requirements for planners and installers: BIM and building contract law"

Q & A session with the speakers on "New requirements for planners and installers: BIM and building contract law", Chaired by: Bernhard Heuvelmann

Away from confrontational relationships between those involved in construction, towards more consensus and communication. This was the most important conclusion of the closing discussion with the speakers from the BIM and Construction Contract Law section and chairman Bernhard Heuvelmann on the second day of the Intersec Forum of Messe Frankfurt.

The participants agreed that the framework conditions for the construction of buildings and the technical building services equipment (TGA) are changing fundamentally. However, both the new building contract law in force since 1 January 2018 as well as the challenges of implementing Building Information Modeling (BIM) and the possible changes in the application of the scale of fees for architects and engineers (HOAI) have not yet arrived in practice. A contract based on confrontation and punishment would not allow the construction of tomorrow's buildings. What is needed are partnership contracts with a transparent design.

The participants agreed that BIM is coming. How stony the road will be, depends on the extent to which all stakeholders work together cooperatively. BIM or the elements of virtual planning are already being used today, for example in the simulation of hazardous situations in buildings. A particular challenge today is the transfer of the data gained through the planning process with BIM into the operating phase and the entire "life cycle" of a building.
