Automating the Creation of Facility and Energy Management Building Information Models

Abstract: Building Information Models (BIMs) are widely recognized as being valuable asset management tools, however the resources required to develop BIMs of existing buildings for Facilities Management (FM) purposes are a recognized barrier to entry. Significant developments have been made for generating geometrically complex models using scanning technologies, however the resultant models are often extremely large, requiring significant computational resources. This paper presents an automated process that uses 2D floorplans and elevation drawings to generate semantically-rich, BIMs with adequate geometry for energy simulation and integration of semantic data of specific value in day-to-day building operations management. The proposed approach is limited to the information available regarding the building and develops a model requiring minimal resources to both develop and maintain, while providing the flexibility for incorporating complex geometry when such information becomes available. A case study of a university campus is presented where 20 buildings were modelled using available 2D architectural CAD files (floorplans and elevations) to demonstrate and evaluate this approach. Process speed, accuracy, and resultant model quality are discussed, along with automation process limitations.

Bridge painting defects recognition using samplying plans and image processing techniques

Abstract: Bridge painting inspection is a time-consuming work that relies on plenty of human visual efforts that are subjective, inefficient, and inaccurate. In order to shorten the inspection / evaluation time and increase the accuracy, two unbiased sampling plans and an automated recognition system were developed with the hope of standardizing and automating the inspection process. The system hybridizes image processing techniques and neural networks, which provide expert knowledge through training, to automatically diagnose the defects on an image. The developed recognition system can process vast number of images instantly and intelligently with simulated human expertise. The detection of rust areas is used to exemplify the recognition system.

A BIM assisted rule based approach for checking of green building design

Abstract: Since the publication of green building standards from the last decade, the designer of green buildings have often encountered the challenges of limited time but considerable complexity in the process of evaluating their design according to the rules specified in the standards. Also, the design process is usually an iterative one, which includes rule-checking tasks that are tedious and repetitive. With the advancement of technologies in Building Information Modeling (BIM), artificial intelligence, and Virtual Reality (VR), this research investigates and develops a BIM-assisted Rule-based approach for automating checking of green building design. The developed approach utilizes as much information available in a building’s BIM model as possible to automate the design evaluation complied with green building standards. It also provides visual feedbacks through the BIM model to assist the designer in green building design. To evaluate and demonstrate this approach, an Application Programming Interface (API) tool has been developed in this research to extend the capability of BIM software for both automatic rule-checking of green building design and real-time visualization of feedbacks from the rule-checking. A rule base is used to manage the design rules specified in green building standards and facilitate the automation of rule checking. In addition, visualization of the rule-checking results (e.g. highlights of places in the design that do not satisfy the design requirements) is supported in a 3D VR environment of a building’s BIM model.

Construction field data inspection using pocket PC technology

Abstract: Construction projects are characterized by the large amount of data that needs to be collected, processed, and exchanged among the different project participants. Collection of construction inspection data, in particular, allows field personnel to monitor project performance with the ultimate goal of improving productivity and lowering costs. Current practices for recording and filing of field inspection data are mainly paper-based. This manual process using paper forms is a time consuming and tedious task. Not only is the clerical expense of this process very high, but also the organization and review of the information commands an inordinate amount of time by a project manager, of which most managers posses very little. Continuous evolvement and improvements of the Pocket PC and its hardware/software technologies, including more powerful processors, smaller storage devices, higher quality displays, and wide availability of third party application software, have made it possible for these devices to become stand alone systems with powerful functional capabilities. Because of their high mobility characteristics due to their small size and light weight, Pocket PCs can be used in the construction field to perform various tasks including recording of inspection data. This paper describes an application for automating the collection process of field inspection data using Pocket PCs. The application allows for recording, processing, and distribution of quality compliance inspection information of various tasks performed in the field. The application is developed using HandBaseTM database software from DDH Software, Inc. and is implemented using a Compaq iPAQ H3870 Pocket PC.

Automating building life cycle energy assesment

Abstract: Building designers and developers are expected to meet an increasing range of constraints on building projects. Normally, the new constraints are part of an established body of knowledge which designers either have to learn or a new "discipline" emerges which has expertise in the new area. While the stock of buildings is improved through these new requirements, both of these paths increase the complexity of the design process with consequent increases in time and cost for the project. LICHEE is an advanced prototype of a system that integrates CAD with life cycle energy assessment. With the addition of some extra information, it automatically estimates the operational energy and embodied energy requirements of detached housing The system was built out of existing components using the Industry Foundation Classes (IFCs) as the "glue" to bind the components together. The use of the IFCs provided significant savings in development time over writing interfaces against the major CAD systems. The software architecture chosen allowed the use of existing stand-alone software components that previously required extra expertise and time.

Design Coordination with Building Information Modelling – BIM: A Case Study

Abstract: Despite some isolated initiatives using 3D CAD or BIM (Building Information Modeling) tools, project processes in the Brazilian AEC industry are still essentially developed using 2D technology, especially in the design development phases. There is evidence in the literature that 2D representations are prone to difficult-to-detect design errors and representation mistakes. BIM is an emerging paradigm based on object oriented, parameterized 3D CAD tools that promises an even better performance in design coordination processes than standard 3D CAD. This work aims to identify the potential for using BIM tools in the design coordination process as a more effective alternative to two-dimensional methods (abstraction and overlaying of drawings for interference checks and clash detection among different design disciplines). The research was based on the execution of a case study involving a complex residential building. Its design was developed as usual, with 2D CAD, as was its coordination process, by professional firms hired by the owner. Afterwards, using the same documents provided to the coordination firm, the first author independently developed the architectural, structural, plumbing, and HVAC BIM models for the standard floor plan of the building, simulating both the Schematic Design (SD) and the Design Development (DD) phases. During and after this process, detected interferences and information errors or omissions were documented in order to be compared with those reported in the traditional process of design coordination. The comparative analysis of both reports in this case study showed that the methodology with BIM detected 75% more design interferences and inconsistencies than the 2D-CAD supported method. This was partly due to the easier visualization of the virtual model, and to the software features for automating interference checks. On the other hand, the analysis of the interferences found in both processes demonstrated that the modeling procedure alone can affect design perception and evaluation, allowing the detection of a greater number of incompatibilities during the process.

A Platform for Automated Technical Building Management Services Using Ontology

Abstract: The deployment of technical building management services is a requirement to further reduce energy demand of future and existing buildings. Automating the process of configuring and deploying technical building management services such as fault detection and diagnosis of technical equipment seems to be a promising path to intensify the adoption of these services. In this work we present a data processing and analytics execution platform which allows the deployment of ontology-based, automated technical building management services on a large-scale. We present the platform architecture and results from a reference implementation performing rule-based fault detection on offline air handling unit data.

A Pattern-Based Approach for Facilitating Schedule Generation and Cost Analysis in Bridge Construction Projects

Abstract: The paper presents a computational method to help in automating the generation of time schedules for bridge construction projects. The method is based on the simulation of the construction works, taking into account the available resources and the interdependencies between the individual tasks. The simulation is realized by means of the discrete-event based simulation software originally created for plant layout in the manufacturing industry. Since the fixed process chains provided there are too rigid to model the more spontaneous task sequences of construction projects, a constraint module that selects the next task dynamically has been incorporated. The input data of the constraint module is formed by work packages of atomic activities. The description of a work package comprises the building element affected, the required material, machine and manpower resources, as well as the technological pre-requisites of the task to be performed. These input data are created with the help of a 3D model-based application that enables to assign process patterns to individual building elements. A process pattern consists of a sequence of work packages for realizing standard bridge parts, thus describing a construction method which in turn represents a higher level of abstraction in the scheduling process. In the last step, the user specifies the available resources. The system uses all the given information to automatically create a proposal for the construction schedule, which may then be refined using standard scheduling software.

AUTOMATED INFORMATION EXTRACTION FROM CONSTRUCTION-RELATED REGULATORY DOCUMENTS FOR AUTOMATED COMPLIANCE CHECKING

Abstract: Manual regulatory compliance checking is usually time-consuming, costly, and error-prone. Automating the process of compliance checking is expected to reduce the time and cost of the process, as well as reduce the probability of making compliance assessment errors. One aspect of automating the compliance checking process is automating the extraction of information (rules that the project needs to comply with) from construction-related regulatory documents (which are expressed in textual format). With the advancements in the artificial intelligence domain, natural language processing (NLP) techniques are being widely used in many fields for information extraction from unstructured text. There have been few research efforts to apply NLP techniques in the construction domain. However, none of these efforts attempted to automatically extract rules from textual regulatory documents. In this paper, the authors propose an approach for semantic information extraction (using domain-specific meaning, in addition to syntax-related text features) to automatically extract information from construction-related regulatory documents and represent it in a computer-understandable, structured format. Preliminary experimental results are presented and discussed in the paper.

AN ONTOLOGY FOR MODELLING AND SUPPORTING THE PROCESS OF AUTHORING TECHNICAL ASSESSMENTS

Abstract: In this paper, we present a semantic web approach for modelling the process of creating new technical and regulatory documents related to the Building sector. This industry, among other industries, is currently experiencing a phenomenal growth in its technical and regulatory texts. Therefore, it is urgent and crucial to improve the process of creating regulations by automating it as much as possible. We focus on the creation of particular technical documents issued by the French Scientific and Technical Centre for Building (CSTB), called Technical Assessments, and we propose services based on Semantic Web models and techniques for modelling the process of their creation.
