In order to ensure the health and safety of occupants, buildings must be inspected to check their compliance to current regulatory requirements prompted by occupancy changes, renovations and building code revisions. Recent inspections conducted by Public Works Canada have identified about 1700 occurrences of code violations in 19 buildings. There is an enormous amount of information that can be extracted from the study mentioned above to implement a knowledge‐based expert system to assist in future building inspections. The philosophy of this expert system is to integrate both knowledge‐based and hypertext representation techniques to enable building inspectors to quickly identify code violations, refer to the code text and provide case study information that can assist in resolving a problem. The present paper describes the development framework and details of a prototype implementation known as the Health and Safety Expert System (HASES). The HASES currently addresses the requirements of ‘Section 3.4: Requirements for Exits’ of the 1990 National Building Code of Canada. The software architecture consists of an external database of building details, an object hierarchy and a rule‐base representing the code requirements, hypertext user‐interface for code text and case study information. The ultimate objective is to make this system available for field inspections using notepad computers.

The residential construction industry has a major share in Canada's GDP. In spite of huge spending and technical advances in the residential construction sector, the current permit approval process still adheres to traditional manual permit approval process. Consequently, this has contributed to project delays and increased monetary costs to the stakeholders associated with the process. The research presented in this paper seeks to explore key issues related to the current housing development permit approval process.

This paper describes a proposed methodology for the automation of the residential construction development permit approval process. The proposed methodology has been incorporated into a computer system that integrates a knowledge‐based expert system (KBES), database management system (DBMS), and computer‐aided design (CAD). Various concepts related to the database structures, system architecture, process flow and user interfaces are introduced and described in the context of the development permit approval process.

This paper presents a knowledge‐based prototype for the development permit approval process that can be customized as per the needs of various cities. A case study is also presented in order to demonstrate the effectiveness of the proposed method and to illustrate the implementation of the research.

The prototype is application‐independent and may be implemented anywhere in the AutoCAD environment. The research paves the way for the setting of drafting standards for the residential industry.

Prototype provides significant gains in productivity and accuracy over the current practices by minimizing the redundancies involved in the development permit approval process.

The purpose of this paper is to review the four stages of approval and describe the process of building certification. It reviews a sample of the inspection and certification records of 109 houses in south‐east Queensland and analyses their progress through each of the stages. The incidence of minor faults and failures is examined, together with requests for further information. Trends in these incidents are enumerated, described and analysed with a view to improving the process.

Access to a private certifier’s inspection data base was given and 109 houses were randomly selected. All the houses were built in 2010 in south‐east Queensland from the Gold Coast, Brisbane and stretching up to the Sunshine Coast. The full range of inspections was conducted to completion. The records of each house inspection at each of the stages were examined, with the detailed notes of each inspection reviewed and analysed. The inspector’s notes were often extensive and detailed and the authors condensed these down into the main causes of problems in approval for that stage.

The results provide an insight into the process of building approval with documentation required to ensure its integrity and satisfactory completion. A summary of the results provides an insight into this performance.

The building control and certification system is working well and the regulations, codes and trained personnel are maintaining high standards of construction and safety.

Safer and better quality house construction should lead to greater consumer satisfaction and confidence in the community.

This is the first time that such a study of the private certification process has been undertaken in Australia.

This article aims to outline the process of developing Codes of Practice and their content and assessment for eight hospitality industry sub-sectors in Abu Dhabi. This is the third article in a Worldwide Hospitality and Tourism Themes theme issue presenting a comprehensive government strategy for improving food safety management standards across the hospitality industry.

The research process gathered quantitative and qualitative data from industry visits, surveys, interviews, document analysis, focus groups and stakeholder workshops.

Standards varied across the industry, with distinct characteristics and patterns across the eight groups. Systems were most likely to be found to be in place within hotels. However, there were some issues with validation, documentation and particularly certification. In other sectors, there were lower levels of food safety management with some additional specific challenges. The baseline data identified, along with regulatory requirements based on international best practice, provided a detailed roadmap for outcomes to be achieved in the Emirate of Abu Dhabi.

The article brings together a theoretical and practical discussion of food safety standards within the hospitality industry, with a unique insight into a practical application in the Emirate of Abu Dhabi. It will be of value to practitioners, researchers, policy makers and other stakeholders involved in the food industry.

In recent decades, professionals in the architecture, engineering and construction industry have come to recognize building information modeling (BIM) as one of the most powerful technologies available to ensure successful project outcomes. The purpose of this paper is to explore the benefits of BIM on design defect prevention during the design phase of building projects.

The authors qualitatively analyzed 160 design defect leading indicators (LIs) to identify key themes for design defect prevention. Then, by matching appropriate BIM functionalities to each key LI theme, they identified BIM-supported key LI themes.

The result of this paper served as the foundation of a BIM-based key design processes framework, which identifies the necessary data, project parties, actions and applicable BIM functions for preventing particular design defects. In addition, the authors found that BIM implementation can benefit 71.2% of the LIs of the design defects associated with problematic deliverables.

This study establishes the current state of BIM use for design defect prevention and also gives practitioners precisely targeted guidelines for using BIM functions during the design phase for better quality management.

The purpose of this paper is to explore the feasibility that an ontological approach can be applied to formalize the construction regulation constraint knowledge in a computer-interpretable way, for construction quality checking, during construction stage.

The ontological and semantic web technologies are used to model the construction quality constraints knowledge into Axioms/OWL and SWRL rules. Protégé platform is selected to illustrate how the construction quality checking, based on the Axioms/OWL and SWRL rules, is achieved.

The ontology and semantic web technologies can be an alternative way for modeling the construction regulation constraints in a computer-interpretable way, and can be implemented for the regulation-based construction quality checking.

The approach is illustrated only with given specific technical constraints examples, the generality and practicality of the approach need further investigation.

The paper introduces an ontological and semantic approach to model and formalize the construction regulation constraints for construction quality checking, and proves the feasibility by the case studies. The proposed approach enables the regulations can be understood and retrieved semantically by computers, which facilitates the using of regulation codes.

Building permitting is mostly a manual, labor intensive and time-consuming process. Initiatives for streamlining the process are not always helpful since they often fail to address the core problems within the process. A framework for modeling the permitting process can be useful to identify bottlenecks, core challenges and best practices. Hence, the authors aim to demonstrate and validate a previously suggested workflow for permit process modeling using the permitting process in Israel as a test case.

The authors implement qualitative expert interviews for data acquisition. The collected data are then processed for a qualitative data analysis. The results of the analysis are then validated using a focus group workshop in the field of building permits. In the test case the focus group consisted of Israeli experts.

The authors present a detailed overview of the as-is building permit process in Israel and the existing challenges. Through this test case, the authors found that the framework is applicable in different countries and that it can provide valuable insights into the core problems within the process. In addition, application of the same framework in different countries can provide comparable results that would allow the authors to identify best practices.

The major contribution of this work is the development and validation of a framework for building permitting process modeling which can be used to identify existing challenges and bottlenecks in the process. Implementing a structured and unified approach provides an opportunity to easily compare processes in different countries to identify best practices.

This paper presents a conceptual design process for developing a maintenance-focused heritage conservation model. Currently, there are several intervention approaches that can be applied in conservation from reconstruction, restoration and repairs to a “do-nothing” approach. This paper examines whether a maintenance solution is more than just an option or a necessity. The aim of the paper is to study the challenges and opportunities when putting more emphasis on the maintenance approach in conservation.

This research was conducted in an Australian context, where many major buildings were constructed from the 19th and 20th centuries and are now categorised as “modern heritage”. three case studies were undertaken to inform this paper and others. In addition, 17 global heritage conservation experts were interviewed, and their responses were analysed. Also, comparative field observations and archival records were examined and used to develop the initial framework model. Finally, using focus group discussions amongst 7 experts, the framework was reviewed and formally validated in order to ensure the development of a useful model for use in devising an effective maintenance management plan and monitoring conditions in heritage buildings.

This paper supports others in a series that have already been accepted by this journal, focussing the research on heritage building conservation being conducted in Australia, the homeland of the Burra Charter. The other papers are entitled (1) model for the maintenance-focused heritage building conservation and (2) engineering in heritage conservation.

The paper examines contemporary issues in heritage building maintenance and conservation in Australia and focusses specifically on the lack of focus on maintenance as a conservation intervention for heritage buildings.

The purpose of this paper is to investigate the benefits that client organisations expect from building information modelling (BIM) investment in Malaysia. Furthermore, this paper investigates the outcomes that, from the stakeholders’ point of view, the BIM approach needs to present.

To achieve this aim, this research employed a series of structured interviews which were conducted with representatives from client construction organisations in Malaysia. A structured questionnaire, containing 34 items, was used to collect data from respondents.

This research’s findings indicated that increased project revenue is one of the most expected benefits of BIM investment. In addition, it has been revealed that the Malaysian construction industry has implemented the BIM approach to project management. Furthermore, the great deal of acceptance among industrial players has been significantly positive, and thereby it can be concluded that the implementation of BIM in Malaysia has lots of potential.

This paper’s finding offers great knowledge, policy, and academic contribution, acknowledging the development of BIM’s implementation within the Malaysian construction industry.
