Research Activities


HTML / WebGL based Client / Server and Microsoft HoloLens


For our 3 components / libraries we work on several generic examples that can be reused by our clients. The following examples are currently in development and we have example code available for all our clients with an active company-wide license.

The client / server development is done in C++ by using (next to our own components) only standard libraries like Boost, therefor all developments can be applied on Windows, Linux and OS-X servers. The client application can run on any modern device (from PC, Android SmartPhone to iPad / iPhone).

Conversion from several open formats is possible, currently Collada and IFC 2x3 TC1 / IFC4 ADD2 are working, CityGML and DWG are in development.

Integrated Example Models from Collada and IFC

Parametric Building Concepts in Context / Parametric Running Engine

The Microsoft HoloLens is one of many VR/AR devices arriving on the market these days. Of course any device can run any software indirectly running on a connected server. However all our components can also run embedded on the HoloLens controlled by your Windows UWP (United Windows Platform) software, this means IFC import, an active Geoemtry Kernel and parametrics are all possible within your HoloLens without connecting to any server.

INCEPTION (active till June 2019)


http://www.inception-project.eu/

INCEPTION realises innovation in 3D modelling of cultural heritage through an inclusive approach for time-dynamic 3D reconstruction of artefacts, built and social environments. It enriches the European identity through understanding of how European cultural heritage continuously evolves over long periods of time.

INCEPTION’s Inclusive approach introduces novel solutions of 3D digital modelling:

• forever: INCEPTION “Time Machine” that represents an innovative use of time-scale for dynamic 3D reconstruction with emphasis on how the modelled cultural heritage evolves over time in association with its built and social environments;

• for everybody: portable, user-friendly and cost-effective hardware and software instruments for 3D capturing, modelling and analysis, as well as INCEPTION Semantic Web technologies and open-standard platform to creating and sharing understanding between various end-user group;

• from everywhere: INCEPTION’s proposed standard procedures for data acquisition and open-standard format for cultural Heritage Building Information Modelling (H-BIM).

RDF is responsible for development of the interoperable sharing platform to store models from surveyed data and reconstructions/simulations related to specific historical periods, in order to sharing knowledge and allow new interpretation and understanding of European cultural assets. This platform is using the new open standard H-BIM based on Semantic Web.

INSITER (active till December 2018)

Intuitive Self-Inspection Techniques using Augmented Reality for construction, refurbishment and maintenance of energy-efficient buildings made of prefabricated components.

Energy-efficient buildings (EeB) have become a priority of the European Commission (EC) to promote and maintain sustainability in the construction sector. Within the recently launched EU research programme “Horizon 2020” (http://ec.europa.eu/programmes/horizon2020/), a particular attention is given to quality-gap and performance-loss between design and realization both in new construction as well as refurbishment of EeB.

The construction sector is characterised by a segmented approach involving a variety of skills and expertise with different roles and responsibilities. During construction, each actor of the construction value-chain must ensure that his contribution fits into a quality framework defined collectively at the design level. The critical mass of EeB in Europe by 2020 will be achieved through sustainable industrialisation of high-performance architectural, structural and building-service components. However, realising the targeted performance in design is hampered by critical shortcomings during on-site construction and refurbishment that cause a lower built-quality and sub-optimal energy-saving in the building lifecycle.

Through new self-inspection techniques, INSITER will fully leverage the energy-efficiency potentials of buildings based on prefab components, from design to construction, refurbishment and maintenance. It will scale-up the use of BIM for standardised inspection and commissioning protocols, involving all actors in the value-chain.

RDF plays an important role in the work packages that focus on software development and connection towards modern BIM standards. The architecture of the IT part of the INSITER solution is developed by the lead technical partners DEMO, Hochtief Vicon, CARTIF, Fraunhover, DWA (Simaxx) and RDF under our lead. Several tools and components are currently in development by all named partners.

PROFICIENT (finished end of August 2016)


http://www.proficient-project.eu/

PROFICIENT aims to create large business opportunities for SMEs in the construction sector by exploiting the newly emerging process of Collective Self-Organised (CSO) housing for constructing and retrofitting energy-efficient residential districts.

PROFICIENT responds to the EU-wide trend of self-organised housing process in order to boost the quality and the scale of energy-efficient buildings. Self-organised housing process --through which a group of homeowners carries out new construction and retrofitting projects on a district scale-- reflects a raising awareness towards sustainability and the increasing self-managing capability of European society.

RDF was leading Work Package 6 concerning the developed open exchange standards and software development. Together with an end-user software vendor and several research organizations a impressive set of software solutions has been created.

The open standard CMO (a development from TNO, CSTB and RDF) was extended with layers for supporting parametrics and geometry in the so called CMO with Extensions open standard. This open standard is used within some of the products of RDF as well as the connection towards BIM (i.e. IFC 2x3, IFC4 and Collada).

V-CON (finished)


http://www.rijkswaterstaat.nl/english/about-us/doing-business-with-rijkswaterstaat/v-con/index.aspx

The Virtual Construction for Roads (V-Con) is a European project co-funded by the 7th framework programme of the European Commission concerning standardisation and implementation of Building Information Modelling (BIM) technology in the sector of road construction and road management.

The V-Con project aims to improve the efficiency and effectiveness of the National Road Authorities by improving data exchange in the civil infrastructure sector. BIM has already been successfully implemented in other sectors and is a worldwide development.

The project consists of two parts: a development/standardisation part and a so-called Pre-Commercial Procurement (PCP) part. The duration of the project is four years and the official starting date was October 1st, 2012.

RDF tendered together with DEMO Consultants for the Pre-Commercial Procurement tender as part of V-CON project. The tender proposal was successful and the sequential proposal for the first paid commercial phase was recognized as being from high quality. The actual development of the proposed solutions in the second and third phase was assigned to other parties.
