Abstract

Purpose

The construction site operates under a hazardous environment that requires a high level of understanding in building systems to minimise accidents. However, the current building education generally adopts paper-based learning approaches that lack hands-on experiences. Furthermore, to achieve Industrial Revolution 4.0 in line with any unforeseen pandemic, the most optimum solution is to transition from physical to technological-based building education. This paper aims to address the problems by proposing a game-based virtual reality (GBVR) for building utility inspection training.

Design/methodology/approach

The feasibility of the GBVR for building the utility inspection training approach is validated on a sample of undergraduate engineering students through user experience (survey) and performance-based comparisons against traditional paper-based training method.

Findings

The results show that the developed GBVR training has higher system usability in terms of visual output and knowledge retention than paper-based training due to visualisation technologies. The GBVR training method has also higher user-friendliness because of the higher motivational and engagement factors through the adoption of virtual reality and game-based learning.

Research limitations/implications

GBVR training required a longer training duration and achieved a lower performance score (effectiveness) but can be improved by transitioning into hands-on tasks. This study has the potentials to be extended to vocational training platforms for competency development in the construction workforce by using cutting-edge extended reality technologies.

Originality/value

This paper portrays the benefits of integrating virtual reality technology in building education to overcome the low practicality and engagement of paper-based training.

Abstract

Purpose

There have been several recent cases reported in Malaysian newspapers of complaints about the impact of construction works on the physical conditions of the surrounding buildings. The purpose of this paper is to present the findings of a study conducted on a complaint received by the Local Authority in Selangor, Malaysia, about the impact of adjacent new construction works on the conditions of existing buildings in the neighbouring vicinity.

Design/methodology/approach

The sample case study consists of 28 units of two‐storey terrace houses, and the instrument used was the inspection form for building inspections. A building survey was carried out for all the buildings in the case study. Two teams conducted the survey. Each team was led by a professional building surveyor and assisted by two assistant building surveyors. Apart from basic surveying tools, a digital calliper was also used to measure cracks. Crack‐width data were collected and analysed using the statistical package for social sciences (SPSS) software.

Findings

The findings show that the adjacent new construction works have impacted the existing buildings nearby. A numbers of cracks of various magnitudes were identified in all the existing houses. One significant finding is that there appears to be no significant relationship between the cracks on the interior and the exterior, nor between the original and the renovated parts, of the existing buildings.

Originality/value

The significant number of cracks identified in the existing houses implies that the cracks were associated with the impacts from the new construction works. However, the primary cause of the building cracks was difficult to determine. It is therefore proposed that the Local Authority should establish guidelines at the local level for new construction works to prepare an inspection report on the condition of existing buildings in the surrounding area before the project commences. Building condition reports can then be used for reference in the event of claims received from the surrounding building owners alleging that the new construction works have adversely impacted the existing conditions of nearby buildings.

Abstract

Purpose

The purpose of this paper is to report on the results of an exploratory study on the use of unmanned aerial vehicles (UAV) as a visual data collection tool in the architecture, engineering, construction and facility management industry for the inspection of pathological manifestations in building facades.

Design/methodology/approach

The methodology used a field research experimental approach, where three case studies were carried out involving buildings of medium and high elevation. The protocol of activities included image collection and processing stages, as well as detailed analysis of the collected visual data for the identification of pathological manifestations in building facades.

Findings

The findings emphasize the technical feasibility and efficacy of inspections with UAV, showing that among the visual assets produced, digital photographs collected with the aircraft were more effective for the detection of pathologies when compared to the three-dimensional models and orthomosaics generated by digital photogrammetry software.

Originality/value

The research has formulated the protocol for the inspection of facades using UAV and the comparative analysis of visual assets that can be generated for inspection purposes.

Abstract

Purpose

This paper is based on a research project sponsored by the DTI, with contributions from construction industry partners. The principal objective of the research was to generate data (based on a sample of new‐build housing schemes) about the levels of compliance with Building Regulations and standards typically achieved in England and Wales.

Design /methodology/approach

The field research consisted of a triangulation of three research methods. A series of observations of 11 speculative housing projects (in Oxfordshire and Gloucestershire) during construction. A questionnaire survey of occupants of recently completed speculatively built houses. A total of 200 questionnaires were distributed in eight housing developments completed 9‐15 months previously. Semi‐structured interviews with six building control inspectors, both local authority and approved inspectors.

Findings

The general conclusions are that levels of compliance were not always sufficient, though there was no evidence of systematic and purposeful non‐compliance with building regulations. Faults were largely due to lack of skills and knowledge of the required standards on the part of the operatives, and shortcomings in site management and toleration of sub‐standard workmanship.

Research limitations/implications

The surveys were limited to projects by national or regional scale housing developers on mainly medium‐large size house developments that included semi‐detached, detached and townhouses.

Practical implications

The recommendations point to the need for more initial and continuing training of tradesmen, both in trade skills and knowledge of the provisions of building regulations, and more rigorous site management procedures adopted, particularly when pressure for completion is at its greatest.

Originality/value

The value of the paper is linked to the originality of the research; prior to it, reliable evidence of the scale and extent of non‐compliance with Building Regulations in the UK was not recorded in any publicly available source.

Abstract

Purpose

The issue of building defects is a growing concern that affects all major construction stakeholders as a result of costs and time implications of reworks. The magnitude of the problem is severe with statistics highlighting defects often result in 4% of the total cost of construction of a building. Despite the importance of this problem, studies have seldom considered development of systematic approaches to enhance the quality control process in construction.

Design/methodology/approach

Building defects is a growing concern that affects all major construction stakeholders because of costs and time implications of reworks. Magnitude of the problem is severe with statistics highlighting defects often result in 4% of the total cost of construction of a building. Despite the importance, studies have seldom considered development of systematic approaches to enhance the quality control process in construction.

Findings

Results indicated that poor workmanship is the main cause of building defects and incomplete works is a frequently detected defect type. Results categorised defects based on cost and frequency to identify the severity. Findings also identified four focus areas including control measures, technology use audit and inspections and promotion of best knowledge.

Research limitations/implications

The study lacks generalisation as it covers only Victorian scenario and further studies are needed to generalise the findings.

Originality/value

The study provides a deeper understanding of the challenges currently facing the residential construction industry in Victoria, Australia, and underlines the need for developing quantitative models and methodologies to improve current processes, practices and policies for effective defects minimisation in Victoria, Australia. The systematic methodological framework can also be adopted by researches across the globe to effectively analyse the options for minimising residential building defects.

Abstract

Purpose

Regular inspection and maintenance is recommended to preserve and sustain built cultural heritage. Systematising inspection processes and knowledge on defects, and providing pictorial guides for evaluating defects is an approach that may facilitate their condition survey. Generating pictorial guides for preliminary visual inspection of Modern Heritage buildings with rendered-painted facade concerning two defects (i.e. crack and efflorescence) is aimed in this study. These guides are thought as aids in determining the defect levels and deciding the necessity of advanced examination and/or maintenance. Analysing briefly the evolution of crack over time in the inspected buildings under environmental conditions of Istanbul (Turkey) is also aimed.

Design/methodology/approach

Preliminary guide generation was based mainly on literature survey on defects, and visual data collection from eight Modern Movement examples in Istanbul. The guides were then refined through systematic visual inspection of three buildings among them. Evolution of crack over time was analysed through a second inspection performed after 2.5 years.

Findings

Visual inspections showed that crack is the commonest defect occurring mostly on projecting structural members, while efflorescence is less in number. Comparison of cracks' visuals taken in the first and second inspections showed that deterioration process is slow.

Originality/value

Modern heritage buildings usually have some characteristic features, which may sometimes lead to accumulation of defects at certain locations or may lead to formation of certain defects. Generating visual guides as a start for an initiative for a comprehensive defects catalogue particular for Modern Movement buildings in line with associated cultural heritage standards may contribute to their preservation by easing the condition surveys.

Abstract

Purpose

Sustaining the safety and operability of the civil infrastructure assets, including buildings, is a complex undertaking that requires a perpetual cycle involving inspection, and further decisions for renewal fund allocation. Inspection, which is the basis for all subsequent decisions, however, is subjective, costly, and time‐consuming. To circumvent inspection problems, this paper aims to develop indicators of the condition of building components, without inspection, using reactive‐maintenance data.

Design/methodology/approach

For that purpose, sample reactive‐maintenance data of 88 schools are obtained from the Toronto District School Board in Canada. The data are then analysed to identify two condition indicators for building components: the number of reactive‐maintenance work orders per year; and the cost of reactive‐maintenance work orders per year. The analysis then identifies threshold values that differentiate the good, fair, poor, and critical conditions of components. Accordingly, a condition prediction system has been developed and discussed in this paper.

Findings

The system has great potential benefits in saving the time and cost associated with indiscriminate inspections, and in providing accurate and timely data for asset renewal decisions.

Originality/value

The paper introduces an essential component of a comprehensive framework for building asset management: condition prediction and inspection planning.

Abstract

Purpose

Growing awareness of the importance of preserving the built environment has created an increasing demand for experts capable of performing building inspections to ensure a high level of preservation. Technical surveys include a set of procedures and tests that have become essential tools providing the necessary knowledge required for maintenance, preservation and improvement of buildings. The paper aims to discuss these issues.

Design/methodology/approach

Within this set of inspection techniques, this paper presents a method developed to produce vertical deformation plans from the levelling data obtained from different floors of a building. It also explains how to perform accurate levelling and an outcome analysis to provide displacement maps. Thus, based upon obtained measurements, it is possible to achieve 2D contour maps and three-dimensional (3D) surface mapping by means of specialized software that is typically used for cartographic and territorial analysis.

Findings

The developed methodology provides easier analysis of the deformation of buildings and structures. Consequently, the method produces relatively accurate outcomes that are sufficient to make a proper assessment that facilitates the diagnostic and decision-making process. The case studies analysed show the applicability and usefulness of the procedure.

Originality/value

This sustainable and non-destructive system is an essential instrument for providing valuable and useful information to the specialist. The 2D/3D graphical data displays enable easier analysis of survey results, also aiding comprehension of these results in the context of liability claims.

Abstract

Purpose

It is well understood that maintenance is critical to the survival and in‐service use of any building. Despite recognition that the best way of protecting and maintaining historic buildings is to undertake a combination of proactive and reactive maintenance, it is rarely adopted or implemented, and when it is undertaken it often results in varying degrees of success. Maintenance theory currently exists, but fails to be realised in practical application and implementation. It is the purpose of this paper to ask why this failure is occurring.

Design/methodology/approach

The paper is composed of a critical review of existing literature, highlighting some of the major issues affecting maintenance implementation. It also reports the early stages of proposed research ongoing at Heriot‐Watt University.

Findings

Despite recognition in the literature of the need to maintain historic buildings, this review suggests that the ways in which maintenance is organised and financed often mitigates against its implementation. In addition, advice to owners of historic buildings could be improved and there is a shortage of skilled operatives.

Originality/value

Unless this situation is improved, much of our culturally significant buildings will be lost to future generations.

Abstract

The majority of the population in Hong Kong live in multi‐storey high‐rise buildings. The safety conditions of these buildings are a major concern of the Government and the public. Fire safety is one of the major concerns especially after several large fire tragedies in the past few years. The Hong Kong Government has introduced a mandatory safety assurance requirement which is called the “Building Safety Inspection Scheme”. Under this scheme, building owners are required to appoint appropriate building professionals to assess the safety level of their buildings and to recommend appropriate actions. One of the major aspects relates to the fire safety. In order to ensure uniform standards and easy administration, the Hong Kong Government intends to publish a Code of Practice on the assessment for use by building professionals. This paper proposes a fire safety assurance approach including the fire safety assessment method which may form the basis of the Code of Practice.
