Computer aided conformance checking

Abstract: In the building process a number of problems exist with regardtobuilding regulations, causing the conformance checking process to be an island in the building process. This paper discusses an approach that enables us to perform computer aided conformance checking and to integrate the conformance checking process in the building process. The approach is based on the use of product models. This paper discusses theoretical as well as implementationaspects. The paper is an extended abstract of the Ph.D. thesis written by the author (De Waard 92).

Towards an ontology-based approach for conformance checking modeling in construction

Abstract: This paper gives an overview of a formal ontological approach of conformance models for regulations in Construction aiming at answering the research question: “is an IFC-represented building project compliant to a set of construction rules?” The study analyses three key subtasks: (i) transformation of the IFC of the construction project; (ii) regulations formalisation; (iii) conformance checking reasoning. While analysing the IFC model redundancy and/or insufficiency for conformance checking reasoning, we suggest an intermediate RDF-based model, semantically en-riched and regulation-oriented. The regulation formalisation is studied under two viewpoints: the formalisation of pa-per-based regulation texts to be automatically used in reasoning and the development of the representation of ontology-based regulations. The construction rules are represented as a set of rules which premise and conclusion are RDF graphs. The conformance checking starts from the alignment of the construction project ontologies to the prem-ise/conclusion ontologies of the construction rule. Then, the checking in construction is seen as reasoning in terms of the corresponding RDF graphs. The paper concludes with a preliminary conceptual framework based on Semantic Web technologies modeling the conformance checking problem, as well as the technical solutions for its implementation. The respective architecture and future challenges of the work are also discussed.

Application of information technology in the building regulatory environment

Abstract: The Building Code and its associated regulations, standards, interpretations, rulings and explanatory support documents form a body ofmaterial which, like any law and its regulations, are complex and, attimes, esoteric. It is comprised of a series of concepts and their relationships, rules, exceptions to rules and examples. It essentially defines prescriptive states, conditions and actions for the builder/designer or identifies performance requirements for materials or systems.There is seldom rationale for the rules that could easily be understood and thus few answers to the question, "Why?". This makes building regulations difficult to develop, to use and to enforce. In this paper some applications of computers used in the Code Development process, as a user tool and as an instructional tool will be discussed.

Intelligent broker for collaborative search and retrieval of construction information on the WWW

Abstract: "CONTEXT In recent years, the construction industry began to use the World Wide Web (WWW) as an information dissemination vehicle. The amount of construction information available on the WWW is increasing exponentially, ranging from product data to technical publications, from building regulations to best practice guides. However, the task of finding the right information becomes more and more difficult. At present, users rely on two types of solutions to the information discovery and retrieval problem on the Internet, “yellow pages like information gateways” and “robot-based Internet search engines”. While acknowledging the success for both solutions so far, the authors will discuss their growing evident limitations in supporting construction specific information retrieval on the WWW. OBJECTIVES AND METHODOLOGY The aim of this study is to develop an intelligent information broker for the construction information on the Internet, which will facilitate collaboration between users for the benefit of improved information search and retrieval on the WWW network. The objectives are: ·to examine the information needs of different types of users in the construction industry; ·to capture these information needs conceptually as user profiles and information context models; ·to incorporate construction domain knowledge into the information network; ·to improve speed and accuracy of users search for construction information by developing a information network that facilitates the sharing of search results and knowledge; ·to develop a hierarchical distributed client/server architecture to enable the most efficient service both Intranet and Internet users. RESULTS AND CONCLUSIONS The intelligent information broker described in paper has a client/server architecture based on software agents technology. It has two distinct features: (1) supporting user collaboration; (2) applying construction domain and user profile knowledge to improve the information search. Collaborative Information Searching Collaborative searching or social filtering is often the most effective method of ranking Internet documents. The developed information broker enables users with the same interest to share the results of their search and their rating of each document’s quality and relevance. Construction knowledge and User Profile The information broker server is in essence a construction oriented WWW searching engine. What distinguishes it from other searching engines is its evolving knowledge base of construction specific keyword sets and construction user profiles. Using the knowledge base, the information broker server is able to answer intelligent queries other than simple keyword matching."

Computer aided development of knowledge in the construction process

Abstract: Modern regulations control the performance of our built environment rather than the methods and materials of construction. The designer has freedom to fulfil specified objectives any way he chooses, but he must show that he is fulfilling the regulatory intention, and fulfilling it well enough. How does he convince the building surveyor that his building will provide an acceptable level of compliance? Where does he find the information to justify his choice of solutions to the regulatory problems? And where does the regulator find the information needed to determine whether or not a proposed solution is acceptable? The answers lie in the sea of regulatory information and research that is the source of all building reedation. Required levels of compliance are implicit in ixaditional, prescriptive regulations. Background research data, legal rulings, records of committee decisions, articles, advisory notes, commentaries, accreditation reports, cornon practice - all give an indication of the level of compliance that society and the regulators are willing to accept and help the designer and the regulator establish criteria of acceptance. This vast array of knowledge helps the regulator determine the intentions of existing regulations and write realistic rules for the performance of buildings. But where does the search fgr knowledge begin? Information technology can structure the search and help find a way through the jungle of data, macheteing obstructions to the introduction of innovative solutions. A structured, selective search can give the regulator access to all the data he needs to support his arguments, allowing the full realisation of the benefits of performance regulation. Linked to a powerful expert system that assists and checks his passage through the regulations, CSBO is creating an IT system to facilitate these benefits.

Construction application of a gen-network : uniform access to standards, products and company information

Abstract: "Facing an increasing competitive environment where flexibility and adaptability to change are the obliged route to success, building and construction companies have to continuously renew their working habits while keeping business processes under quality, time and cost control. In the Architecture, Engineering and Construction (AEC) domain, the wide diversity in terms of the object built, but also associated to the geographical dispersion of actors and building sites makes such an agility even more crucial. Considering the design and tendering phase of a construction operation, the architects and construction engineers have to efficiently select the manufactured products that will best suit the project while complying to its numerous constraints. Beyond the functionality, performance and cost characteristics, a suitable product has also to conform to the applying regulations and standards, be eventually accompanied with a corresponding technical agreement, offer acceptable delivery solutions on the building site. Moreover, once identified within a manufacturer catalogue, the product has to be integrated into the architect or engineer application desktop, whether it be a CAD, specification writer or quantity take-off application. Addressing these needs, the Global Engineering Networking (GEN) initiative is promoting the reuse of company internal and external engineering knowledge through the emergence of new kind of global market places where actors publish and retrieve on-line a wide range of engineering information and services. In particular, The Construction Pilot in EP 22 284 GENIAL project demonstrates over the AEC domain, the relevance of new generation of Information Technology infrastructures supporting the erection of Value-Added Service Provider (VASP) sites that materialise the GEN vision, i.e. allowing information and services to smoothly be retrieved where required whilst the succeeding company is concentrating on its core competencies. With such an infrastructure, whether it is through material, performances, manufacturer, regulation or price discrimination, the appropriate component, document or service is rapidly and cost effectively brought on the designer desk for the best value of the overall project. On the other side of the communication pipe, the supplying partner gains the opportunity of reaching an enlarged audience as IT now commonly break any geographical distance. In practice, three major information publishers and a building contractor in Europe initiate the GEN network in the AEC domain through the erection of VASP sites offering product, company or document related information. User queries are governed by various standard (EPIC, UNICLASS) or corpus specific (BATIBASE, EDIBATEC) classification systems. Relevance of the overall approach is demonstrated through the presentation of a large variety of such queries for the various information corpuses used : Techcom company and product information, BIC company, product and document, REEF regulation documentary corpus or EDIBATEC product information."

Extracting representation from structured text: initial steps

Abstract: A great deal of work has been done in the past on natural language recognition within the field of artificial intelligence. The aim of this work was to allow natural language text to be read in by a computer and structured in a format that would allow automatic interpretation of the text. This was intended to reduce the "knowledge engineering bottleneck" that has been a significant constraint on the use of artificial intelligence techniques within many fields. Some similar work has also been done within the AEC industry concentrating mainly on building codes. The research project described in this paper aims to simplify the analysis of structured text and its conversion into computer interpretable forms by providing support with computer software. The work is built around two documents - a glossary of building terms used in Australia and the Building Code of Australia. The various issues concerned with "noise" in the source data, the structure and content of documents to be analysed and the desired computer interpretable result will be presented. This work is motivated by: · the need to maintain BCAider, a knowledge based system that assists in checking building designs for compliance with the Building Code of Australia; · continuing work in encoding of regulations in computer interpretable form; and · the need for international glossaries to support information harmonisation efforts such as the IAI and STEP. The software suite under development assists people with some understanding of language structure and knowledge engineering in converting structured text into computer interpretable form using a visual user interface. The current state of the design and development of this software suite will be described and the results of its use presented.
