DhochN is on the list
Accredited educator
of buildingSMART Germany.

From September/October 2018!

Our training and education program "BIM Basis", which is based on VDI/bS 2552-8.1 and LOF-bSI-Basis-D, has a long tradition - we have been training the basic contents since winter 2014. buildingSMART Germany's initiative enables us to offer interested parties an international comparable, systematic introduction to Building Information Modeling.

We organize our seminars exclusively in cooperation with

  • Chambers and their further education academies
  • State universities
  • Companies with their own qualification programs

and also in their rooms. Current dates below.

As a training provider offering the buildingSMART certificate, we offer our course participants to take the online exam provided by buildingSMART International. Only participants who successfully pass this exam can receive the certificate and will be listed in a public register - if they wish so - by buildingSMART Germany.

For the participation in the final examination we have to charge an additional fee, which also includes the reduced purchase of the VDI/bS guideline 2551-8.1.

Digital planning and Design – A Challenge And An Opportunity

"Architecture and BIM are no antipodes" is the title of the lecture by Ajna Nickau at this congress organized by the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety within the framework of the bautec 2018 on February 20, 2018 in Berlin.

In the construction value chain, we are also increasingly confronted with terms such as efficiency improvement, process optimization, networking and standardization. But what does all this mean for our everyday lives in planning, construction and operation? This detailed basic seminar provides the answers to these and many other questions.

Who sets the standards?

We define standards and practice transparency. The DhochN team gives informative presentations, helps others in seminars and has been involved in standardization committees for many years:

DIN – NA005-01-39AA BIM 04AK – Data Structures For BIM Catalogs

The working committee 39 (39AA) within DIN NA005 works as the German mirror committee to the CEN-TC442 WG-4 Data Dictionaries and bundles German interests in European standardization. buildingSMART deployed Siggi Wernik as an expert.

CEN – CEN-TC442 WG-4 – Data Dictionaries

The Technical Committee (TC) 442  Building Information Modeling (BIM) within the CEN (Comité Européen de Normalisation / European Committee for Standardization) has established four working groups to process rules in connection with BIM as part of European standardization. Rules governing the unified, software-neutral descriptions of properties of objects and products are developed in the WG-4 Data Dictionaries. Siggi Wernik has been deployed by DIN to participate in the international working group.

VDI – VDI/bS Directive 2552-8 „Qualification“

The professional qualification of process stakeholders has not been uniformly described to date. This directive is intended to provide fixed definitions of required qualifications, in order to be able to classify stakeholders either as users with basic knowledge or users with in-depth knowledge. Ajna Nickau serves as a member of the responsible working group.

The Federal Chamber of German Architects (BAK) – BIM Project Group

In 2015, the Federal Chamber of German Architects (BAK) formed a project group to promote exchange between countries and various initiatives. Siggi Wernik and Ajna Nickau are permanent members of the project group. Ajna Nickau contributed to the publication "100 Fragen – 100 Antworten" ("100 questions – 100 answers") in this capacity. Both of them were members of a BAK delegation to the RIBA in London in 2016.

Berlin Chamber of Architects – Working Committee Education

In the fall of 2017, the representatives' assembly of the Berlin Chamber of Architects elected Ajna Nickau to the working committee, of which she is the deputy chairman now.

Berlin Chamber of Architects – Digitalization Working Group

In the autumn of 2016, the Berlin Chamber of Architects hand-picked several people to form the digitalization working group. It focuses on strengthening the available training options as well as making contact to local public developers. Ajna Nickau is a member of the working group - .

buildingSMART – Door Schedule Project Group

Based on the fact that "door schedules are different in every architectural firm", Siggi Wernik initiated the buildingSMART door schedule project group. Manufacturers of doors and door components work with architects and engineers to develop a uniform description system for doors to account for a property's entire lifecycle. We have now subjected this extensive system to a proof of concept

buildingSMART – Product Data Room

The product data room is used to define a generally valid solution to the problem of describing products in data form. Every manufacturer, every authoring tool (software), and almost every user currently apply different names and classifications to the data. Standardization in this regard would be of great help to us in practice. Siggi Wernik heads the product data room as a member of the board at buildingSMART's German Chapter.

buildingSMART– Working Group Accreditation

Based on the VDI/bS directive 2552-8, buildingSMART International (bSI) has established an international certification system. The German Chapter is defining standards in this regard. It develops the principles used to list and accredit training providers. The certificates are awarded by buildingSMART following successful testing. Ajna Nickau is a member of the working group

Architecture | Architect's Perspective

In the past few years, the topic of Building Information Modeling (BIM) has become increasingly important in the construction industry. BIM is met with both enthusiasm and fear. A big misinterpretation of the concept is the primary reason people have such different reactions to it. As if there is a BIM method or a BIM project. ...

DhochN in 13 Statements

1. We know the smell of concrete.

The DhochN team consists of experienced engineers and architects with extensive planning and practical building experience. We work and consult our clients based on this foundation, thus providing them with proven and reliable solutions. We apply the methods ourselves and help our customers benefit from our experience. The founders are BIM protagonists and together have 99 years of practical experience.

2. Are you still researching, or are you already working?

Everyone is free to take their own path to implementing digital methods. We did this ourselves and it took us a good decade. Today we are capable of applying digital methods to their full extent.

3. Transparency in construction.

Others talk about it. We live it. In our interdisciplinary team, we have found that the best way to exchange data does not consist of actively sharing it. The best way consists of permanent access to the data and models of the other stakeholders. We practice this in an open system of authoring tools, calculation and simulation software, tools for collision control, and budget and schedule monitoring.

4. Building is fun again! ... Planning too!

Quote from Volkswagen Financial Services after successfully implementing their first project with us: "despite a number of repetitive services and an additional model integration service provided by DhochN, the total budget was not fully used."

5. 3D, 4D, 5D, ... DhochN.

We use building modeling, model-based cost estimation and schedule monitoring, we provide data for operation, we offer consulting in the creation of model-based tender documents. We are not involved in attempts to define 4D, 5D, 6D, etc. We supply all the Ds that the project team requires.

6. BIM – Building like they did in the Middle Ages!

The separation between architects, engineers and construction companies has only existed for around 250 years. When consistently applied in the construction value chain, digital methods can help us work together again at eye-level. Together, we create the best possible result.

7. We know the length of your ladders.

No joke: Our models can actually be used to determine the requirements of the equipment that people need on location. At the construction site. And in the company ... including the length of a ladder required to replace a light bulb.

8. Do you remember the construction tendering and contract regulations?

We model it as it is built! And we mean that literally! The model becomes the building's digital twin in all details. Our models contain all the information we need for billing the actual services rendered. This establishes a basis of trust among our customers and the involved construction companies, who use "net amounts" for accounting instead of the Construction Tendering and Contract Regulations.

9. Do door schedules always have to differ?

... not if it's up to the suppliers. After all, they know quite well which information they need from the planners in models, drawings and schedules. We summarize and bundle this knowledge. We provide a coordinated set of information requirements, which allow for planning, tendering, ordering, installation and operation of each individual door.

10. We like containers. But do you know the packing list?

We don't either. So far, IFC is actually nothing more than a container without a packing list. We ensure the exchange of all data that a building model can provide. The IFC format can not yet provide for this without some losses. That's why we are working to ensure that the export and transport of data is completely software independent.

11. We have abandoned the tape measure.

Whenever possible, we avoid LOD (Level of Detail). Instead, we use objects that transport information in the form of data required by the project team and the customer. The object remains visually simple, serving as a placeholder and carrier of information, not as a model for the catwalk.

12. The BIM Manager as a dominatrix

It's sad, but true. The job of BIM managers, as it is currently defined, is difficult to perform without being a hardliner. After all, if all parts of a planning and implementation team are working with different software and methods, yet still have to regularly exchange all readable data, then very strict guidelines have to be enforced. Continuous strict quality management is mandatory. What we call for, on the other hand, is becoming a team and working together harmoniously.

13. b.i.m.m tools make people happy.

Yes, we work with Revit (among others). We were not satisfied with the software and its features, so we use a comprehensive package of tools, that our cooperation partner, the b.i.m.m GmbH, has developed. Tools that beautify each process involved in model creation, from the first wall to the finished as-built model.
