Integrating building information modelling with sustainability to design building projects at the conceptual stage

Lately the construction industry has become more interested in designing and constructing environmentally friendly buildings (e.g. sustainable buildings) that can provide both high performance and monetary savings. In general, sustainability integrates the following three related components: (1) environmental, (2) economic, (3) social well-being. Incorporating these components at the conceptual stage is achieved by using sustainable design, through which designers must identify associated materials and systems based on any selected certification (rating) system. The use of building information modelling (BIM) concepts helps engineers design digital models that allow owners to visualize the building before the physical implementation takes place. To apply BIM concepts, designers use tools to create 3D models of buildings where the design materials and systems are selected from the built-in database of these tools. Designers will not be able to quantify the environmental impacts of these materials to support the decisions needed to design sustainable buildings due to the following reasons: (1) a lack of information about the sustainable materials that are stored in the database, (2) a lack of interoperability between the design and analysis tools that enable full life cycle assessments (LCAs) of buildings. This paper presents a methodology that integrates BIM and LCA tools with a database for designing sustainable building projects. The methodology describes the development and implementation of a model that incorporates a database in which information about sustainable materials is stored and linked to a BIM (3D) module along with an LCA module and a certification and cost module. The goal of this model is to simplify the process of creating sustainable designs and to evaluate the environmental impacts (EI) of newly designed buildings at the conceptual stage of their life. An actual building project is presented in order to illustrate the usefulness and capabilities of the developed model.     

Manipulating the flow of design information to improve the programming of building design

The increasing complexity of modern buildings and the use of fast-track methods of procurement systems has meant the expeditious and successful completion of the design phase of a project has become ever more important. This paper describes a research methodology that can help plan the building design process. Design models, based on data flow diagrams, have been developed to map information flows during the design of a modern building. These models are analysed using Steward's design structure matrix, which allows ordering of the tasks to produce schedules or design plans based solely on information flowing between design tasks. Traditional ordering is based on experience but modern complex projects require a more rigorous approach. Design is an inherently iterative activity and design structure matrix analysis reveals how to order most efficiently interdependent tasks and use estimates of design information further to improve the scheduling of design tasks.     

Applying building information modeling to support fire safety management

Building information modeling (BIM) is useful in three-dimensional (3D) visualization and data/information storage for planning and maintaining building projects. Recently, researchers globally have been exploring the applications of BIM. In this work, a BIM-based model is designed to support fire safety management of buildings. The model comprises four modules — evacuation assessment, escape route planning, safety education, and equipment maintenance. The evacuation assessment module integrates BIM with a Fire Dynamics Simulator to calculate the required safety egress time and the available safety egress time to evaluate the ability to evacuate in case of fire. The escape route planning module utilizes BIM to determine whether the distance of an escape route is acceptable. The safety education module presents hazardous areas, videos of escape routes and directional maps, all in three dimensions, to educate the occupants of the building about fire safety. The equipment maintenance module is implemented in a web-based prototype to support maintenance tasks in a remote management manner. The results of applying BIM have demonstrated that BIM can effectively provide 3D geometric data to support the assessment and planning of fire safety (using the first three modules), and it can store information in support of safety management and property management in a web-based environment (using the equipment maintenance module).

The advantages of information management through building information modelling

As building information modelling (BIM) is positioned by governments and construction professionals as a solution to the problems in the construction industry, research is needed into the benefits BIM actually confers. The focus here is on the effectiveness of BIM as a medium for communicating information within a construction team. A case study of an offsite precast concrete fabrication facility was conducted. At the time of the study, the facility was supplying precast units for four public sector projects, and using four information management systems: e-mail, a construction project extranet tool, an Enterprise Resource Planning system and a new BIM-based system. The flow of information through the four media was measured and visualized as the projects progressed. This quantitative measurement of information flow was combined with qualitative data from interviews with facility staff. It was found that the introduction of the BIM-based system diverted information flow through the building model and away from the extranet system. The use of e-mail was largely unaffected. BIM allowed considerably more accurate, on-time and appropriate exchange of information. It is concluded it is possible to quantify some of the benefits of BIM to information management. This research paves the way for future research into the management of more construction project information linked more closely to building models.     

A generic building product model incorporating building type information

Building product models are presented as an integrated representation for use in translating information between current and future design applications. Using an information model developed for design applications, we specify a Generic Building Model that represents both the physical and abstract information necessary to model basic knowledge about buildings and architecture. The Generic Building Model and its subsidiary concepts are reviewed. We show how it can incorporate building type information, and include the needs of various activities for comparison against the constructed form. We illustrate the model's behavior by showing how it can be adapted to model information relevant to hospital design.     

A framework to integrate object-oriented physical modelling with building information modelling for building thermal simulation

This paper presents a framework for integrating building information modelling (BIM) and object-oriented physical modelling-based building energy modelling (BEM) focusing on thermal simulation to support decision-making in the design process. The framework is made of a system interface between BIM and Modelica-based BEM and the visualization of simulation results for building designers. The interface consists of the following two major features: (1) pre-processing BIM models to add required thermal parameters into BIM and generate the building topology and (2) translating BIM to Modelica-based building energy modelling automatically and running the thermal simulation. The visualization component presents the simulation results in BIM for designers to understand the relationship between design decisions and the building performance. For the framework implementation, we have created a ModelicaBIM library and utilized the Modelica Buildings library developed by the Lawrence Berkeley National Laboratory. We conducted a case study to demonstrate and validate the framework simulation results.

Construction time information system for the building industry

The paper describes a computerized construction time information system for time planning of buildings at early stages of design. A sample of 29 commercial, privately funded buildings was used to develop the proposed model. A procedure for extending the model to other project categories is shown. Multiple linear regression analysis of sample data shows that the durations of activity groups: substructure,superstructure, cladding, finishes, services and their sequential start – start lag times can be predicted from 12 variables: grossjloor area, area of groundpoor, approximate excavated volume, building height,number of storeys, end use, cladding type, presence of atrium, building location, intensity of services and site accessibility. An experiment involving nine planners and three office projects showed that the time predictions of the model fall within the distribution of planners' estimates and are tatistically indistinguishable from them. Therefore, the model can produce reliable estimates of construction times.
