BIM: The Importance of Communication

Master thesis by Maria Herroros, December 2016

Winner of Innovation Competition “Sprirekassen” by Bikubenfonden, Feb. 2017.

Abstract

Building Information Modeling (BIM) methods started to be implemented in the Architectural Engineering Construction sector (AEC) in order to make the industry more efficient, innovative and with better quality on the project delivery, reducing costs.  BIM replaces the traditional way of communication, 2D drawings, by using 3D models, where all data is gather in one place and all parties of the project can access to it. However, the transition of work methodology is a slow implementation process due the use of new tools and the need of skilled people, while the industry is not completely prepared yet.  Communication, is essential when using BIM method to achieve good results, avoiding misunderstandings, hence, BIM is a collaborative sharing process.

During different stages of a building project, there are minimum requirements that must be accomplished in the deliveries. When talking about BIM, it is meant to the level of development (LOD) of building model elements and BIM model level. The LOD specifies how accurate the model element is, and what information should contain. This concept is still confusing for most of the departments, and needs a deeper comprehension in the beginning of every project, also when there is a collaboration with international colleagues, who use other country standards. These issues could be accomplished by using effective communication tools.

The objective of this thesis is to build a solution, which will improve BIM communication between project disciplines, helping to understand LOD´s among project stages and cross countries. The solution is built according to the company demands, Arup engineers, focusing on the Mechanical Electrical Plumbing (MEP) department that divided between Copenhagen and London office, and data exchange between them in a case study project.

The method is created through a development process, which is documented in this report. The process consists in a first evaluation of the company´s needs and improvements required in the MEP department. Based on findings, a tool is created to improve information exchange between engineers, speed up workflow and achieve requirements, requested to deliver in every project stage. The tool is called BIMapping.  BIMapping is created as a web-based page, hence, all information is digitized and gathered in one place.

BIMapping, is presented in the main page interface. This main page is a single entry to all knowledge included, and represents a mapping on the standardization levels. The main page is divided into three main sections, which guides the user through the whole project process and gives a deep information of LOD and BIM levels, required at every point of the project for building services.

The solution is reviewed and tested by BIM experts, who contribute with their feedbacks to the development of BIMapping and future studies.

The tool should not be seen as a final solution, but as a startup initiative which was welcomed and appreciated by BIM experts, as a good element to be implemented in BIM project process.

Proposal: Lyngby Smart City Data Portal (Project framework)

Under “Vidensbyen” partners for the Lyngby Smart Cities activities have agreed on a cooperation that opens for many possible projects for students in the area of smart cities, big data, GIS, BIM, renovation projects, city planing and much more.

The project will be very dynamic. Hence you ought to ask for current activities to join. The projects will involve partners from industries, from the municiplaity and other partners. (see patner list on the home page of Vidensbyen)

Proposal: Commissioning & BIM – DTU Building 202

DTU Campus Service is one of the frontrunner for commissioning and BIM. The newest project Building 202 is “state of the art” in these processes and there is a lot of knowledge to gain by being part of these processes.

We are looking for students that qualify

  • the commissioning process for the building
  • the BIM delivery process

If you having interested with respect to such processes, you will be part of the most ambitious building developments in our time in Denmark. We would prefer to have a team of students to do the work in combination.

We will be the right supervisors in close collaboration with DTU CAS, consultants and architects. Contact med for getting it started http://www.dtu.dk/Service/Telefonbog/Person?id=2685&cpid=1634&tab=1.

3D BIM for a comprehensive design proces – Theis Andersson

Project name: 3D BIM models – a more comprehensive design proces

Project student: Theis Andersen

Publication: En bedre sammenhæng i projektet (Danish, educational) (2013)

Course type: Special project, Autumn 2012

Supervisor: (Al)Fred Heller

Summary: The vision is to develop a web configuration tool through which customers are able to configure the building they want to buy. To be able to do so, the information describing the buildings, the products, characteristics and configuration options must be represented. This is done partly in a Building Information Model (BIM) in 3D CAD model within the tool Revit. The project defines a prototype building in Revit, informs the details in the BIM part and utilizes a set of components and computer programs to compute relevant information on e.g. price, scheduling, energy demand, indoor climate modelling and much more. For this purpose, the following components are applied:

  • Rockwool Energy Design (for the Danish building code computations) – alternatively Be10 can be used.
  • Sigma (for price calculations)
  • Navisworks (for planing)
  • Ecotect (for energy and indoor environment, daylight computations)

Most integration between the components has been possible, but the integration with Be10 did not work within newest versions, hence Rockwool Energy Design was applied instead.

Vision talk: Decision making towards a sustainable future demands interoperability between tools that generate and collect information on the decisions to be made. For building design, design tools must be supported dynamically by technical software from many different technical domains. It is not probable that there will be a single tool, handling all the computations. Hence a platform model is preferable.

Next step: The current project is a small step in a long process. There is a need for interoperability, getting the tools to work together in a automated way. The BIM data models are to be expanded, pricing more realistic and much more.  The whole integration with the web interface for configuration is not yet taken up. A simple way of doing so could be to dump the intermediate results and information in a file-tree to be utilized from a web solution.
