Suitability of BIM for enhancing value on PPP projects for the benefit of the public sector

Collaborative integrated working and stakeholder’s interest have been among key drivers that underpin and encourage the use of Building Information Modelling (BIM) within the AEC industry. BIM is becoming a major means to deliver projects with better improved product, and reduced risk within the construction industry. Furthermore, using BIM in areas like buildability, quality assurance, cost and scheduling can be justified through BIM-nD modelling application. What is not so obvious is how the utilisation of BIM visualisation and knowledge embedment will enhance these areas to refine and achieve better value for PPP procurement projects for the long term benefit especially during post-construction phase for the public sector. As of now there is no well-defined guidance with respect to BIM usage incorporating all of the above. Do we really need to revisit the way we specify projects within the contractual framework under PPP? This paper examines the possibility of how BIM can be utilised in the realisation of augmented formal database information management system under the PPP procurement routes with respect to operation and maintenance support. The paper concludes with additional measures that BIM can offer at the post-construction phase for the public sector at learning organisations

Integrating BIM and Planning Software for Health and Safety Site Induction

Project management software packages have been around for quite a long time to help managers to run construction projects effectively. Building Information Modelling – also known as Object-orientated Modelling technology was used at the beginning in architectural design which has become more widespread in structural and services engineering. The development of BIM modelling has made the tool more users friendly. As a result, BIM became widely used by most practitioners in their specialist areas. For health and safety practitioners within construction project management, This tool has not been fully explored. BIM technology has the potential to be used in safety planning procedures particularly those related to tasks on construction sites. The section of the research presented in this paper intend to explore and review health and safety issues on construction site with the sole intension of using better visualisation software to meet the needs of health and safety site practitioners in understanding such H&S problems. A framework needed for better H&S practice on site that may be used actively by all practitioners will be developed. The intension is to find a way forward in addressing ‘real’ health and safety site issues that may not be easy to be understood by practitioners without the full aid of visualisation.

A strategic perspective for managing socio-technical systems: the missing link

Most man-made systems around us are mainly socio-technical systems. As such it is imperative that to manage such systems effectively we need to understand their properties at both the micro and macro level and the holistic functioning of such systems. Such an approach is important in understanding the emergent properties that are exhibited by such system. We already have been delving into the micro level and the intricacies of the different subsystems without actually having the broader view of the whole system. This current approach came from the fact that reductionism is the ‘mantra’ of our scientific nature and endeavours, and dictates how a problem is solved. In this paper a strategic approach is put forward, making use of the force field theory as a necessary missing component for designing and managing socio-technical systems. With this proposed strategic approach the true understanding of solving these emergent properties will be reinforced with what we already know and also help in solving some disorder exhibited in these systems, without creating more uncertainties. This paper sets out the framework and its usefulness to understanding the socio-technical systems around us

An Overview of the Feasibility of Achieving Level 2 Building Information Modeling by 2016 in the UK

The aim of this study is to investigate the current status and feasibility of achieving Level 2 BIM (building information modeling) usage that is to be made mandatory by the UK government on its projects by the year 2016. This study assesses the level at which organizational and practitioner knowledge of BIM is currently positioned. The UK government, being the largest public stakeholder client, has realized the benefits and advantages of BIM when used in procuring projects across their lifecycle in the built environment. A critical review of the BIM literature was carried out and the evidence base was created in relation to government targets for 2016. At the current stage, Level 2 BIM adoption is achievable by 2016 for large construction firms but not for SMEs (small medium enterprise). Also, from evidence in this study, the technology needs to be properly tailored to meet SME variables if Level 2 status is to be achieved for the entire industry

Achieving Level 2 BIM by 2016 in the UK

The growth and advantage of Building Information Modeling (BIM) has recently gained momentum in the expanding needs of the construction industry, one that varies across disciplines. The UK government is the largest public stakeholder client that has realized the benefits and advantages of BIM when used in procuring projects. The usage and adoption of BIM in all UK government-procured projects with a Level 2 BIM status will be mandatory by 2016. Will this target be achievable by 2016? This study investigates that possibility. A critical review of the BIM literature was carried out and the evidence based on the government target of 2016. At the current stage, it appears that Level 2 adoption is achievable by 2016 for large construction firms. However, the technology needs to be properly tailored to meet SMEs variables, if the Level 2 status is to be achieved for the entire industry

A conceptual approach to determine optimal indoor air quality: A mixture experiment method

Achieving good air quality in large residential and commercial buildings continues to be a top priority for owners, designers, building managers and occupants. The challenge is even greater today. There are many new materials, furnishing, products and processes used in these buildings that are potential source of contaminations and pollutants. A common problem to the indoor and outdoor environments is that of exposure to mixtures of air pollutants. Researchers and practitioners tend to focus on single pollutants (e.g. CO2, PM2.5) ignoring the mixtures combined effect. Fashion dictates to study the pollutant most thoroughly talked about. Distinguishing the effects of such co-pollutants is difficult. The conclusions about which component of a mixture is actually producing a given effect are sometimes less soundly based than could be wished. It is especially important in considering the indoor mixture of air pollutants as this mixture may be entirely different from those found outside. Exposures to raised levels of air pollutants can damage health, for example carbon monoxide can cause death and significant lasting disability. Controlling levels of indoor air pollutants is therefore important, as good indoor air quality is essential to health. There are three strategies for achieving acceptable indoor air quality: ventilation, source control and cleaning/filtration. Depending on the building and the specific characteristics of the location, these strategies can be used singly or in combination. However, mixture experiment would throw more light and understanding into indoor air composition and interaction properties and the combine effects it has on human health. Mixture experiments have been used extensively in other industries, for example the pharmaceutical industry and the agrochemical industry, for the production of tablets and the control of plant diseases and pests. Developing a mixture model for the internal microclimate for a particular building type and/or location may help us in developing better indicators, standards and policy document in the near future, when the levels of pollutants concentration can be successfully predicted

BIM and project planning integration for on-site safety induction

Purpose – The section of the research presented in this paper reviews and explores health and safety (H&S) issues on construction sites. It has the sole intention of using better computer visualisation to meet the needs of site practitioners in understanding such H&S problems. Design/methodology/approach – The methodology follows a traditional literature review approach to understand the development of BIM technology up to its current status. A questionnaire survey was conducted to gather information on the embedding of H&S planning by site practitioners within the BIM environment. Findings – BIM has the potential to be used in H&S planning procedures, particularly in those related to tasks on construction sites. A framework for an integrated visual tool is developed for better H&S practice on site. It may be used actively by all practitioners, starting with site induction, and addresses, inter alia, personal hazard perception. Research limitations/implications – This paper provides a foundation for developing a tool that helps construction personnel explore potential H&S risks on site before construction begins. By introducing a framework for integrating BIM and project planning, a prototype can be developed to demonstrate the application of the proposed framework. Originality/value – The research presented in this paper introduces BIM usage during the construction stage as a tool that supports a H&S toolbox. The paper proposes the useful framework for better H&S practice on site that can be used actively by all practitioners. The intention is to find a way forward in addressing ‘real’ H&S site issues that may not be easily understood by practitioners without the full aid of visualisation scenarios

Sustainable building solutions: a review of lessons from the natural world

The realisation that much of conventional. modern architecture is not sustainable over the long term is not new. Typical approaches are aimed at using energy and materials more efficiently. However, by clearly understanding the natural processes and their interactions with human needs in view, designers can create buildings that are delightful. functional productive and regenerative by design. The paper aims to review the biomimetics literature that is relevant to building materials and design. Biomimetics is the abstraction of good design from Nature, an enabling interdisciplinary science. particularly interested in emerging properties of materials and structures as a result of their hierarchical organisation. Biomimetics provides ideas relevant to: graded functionality of materials (nano-scale), adaptive response (nano-, micro-. and macro-scales): integrated intelligence (sensing and actuation at all scales), architecture and additional functionality. There are many examples in biology where emergent response of plants and animals to temperature, humidity and other changes in their physical environments is based on relatively simple physical principles. However, the implementation of design solutions which exploit these principles is where inspiration for man-made structures should be. We analyse specific examples of sustainability from Nature and the benefits or value that these solutions have brought to different creatures. By doing this, we appreciate how the natural world fits into the world of sustainable buildings and how as building engineers we can value its true application in delivering sustainable building

Holistic Learning: A workforce development paradigm

The development of workforce knowledge, skills and attitudes are widely acknowledged in extant literature as being pivotal levers to deliver process improvement and efficiency. The success of an organisation depends as much on its technical system as on the social system that supports it. Strategies for improving organisational performance need to incorporate arrangements for developing the workforce competences required to implement strategy. Lean construction by definition involves continuous small-step improvements (Kaizen), problem solving and employee involvement at all levels. The argument for providing workplace systems that support life-long learning within construction businesses therefore takes on greater significance. This paper reports on the pilot for a wider research aimed at firmly linking construction businesses to the learning domain. The pilot involved a survey of domain experts (276) which sought to characterise the Nigerian construction industry in terms of its knowledge and learning requirements, the supply systems for construction skills, the individual attributes required for optimal performance, and the appropriate pedagogical approaches for learning construction skills. Findings to date suggest that the Nigerian construction industry exhibits many characteristics of Taylor-Fordist systems but with tendencies towards knowledge-based systems suggesting the need for improved systems of learning. The training systems of construction firms were found to supply a small percentage of skilled workers to the industry pool, but the few were perceived to be the most competent. Construction skilled workers were perceived to require not only cognitive but also emotional and social competencies for optimal performance. This paper posits that the construction industry needs to align its skill provision systems with modern learning theory to create effective learners and learning environments within organisations to drive the learning needed for performance and innovation. The paper proposes the development of a conceptual model which captures the key elements of an effective skills learning solution for construction

INNOVATIVE INTEGRATION OF MODERN TECHNOLOGIES FOR HEALTH AND SAFETY DECISION MAKING IN THE CONSTRUCTION INDUSTRY

Health and Safety (H&S) has been one of the key issues in the design and implementation of projects within the construction sector. At the design stage of a project, usually designers are accused of failing to appreciate most of the construction processes that will optimise safety and minimise cost. Therefore, clients and other stakeholders are apprehensive as to whether the designer’s input should be fully integrated through other known ways. Also, within a continuation in the downstream end (i.e., construction and facilities management) professional processes used are not fully appreciated by designers. As such these sets of practitioners need to learn fully from each other and integrate their knowledge and skills to close the existing knowledge gap among practitioners. Modern technological innovations have given us new ways of understanding and finding solutions to such existing problems with most professionals working in a collaborative way. Such collaborative ways can enhance learning and cross pollination of professionals within an organisation and across organisations. However, the evidence through data collection is not captured across projects. This conceptual paper aims to integrate modern Artificial Intelligence (AI) and other software applications (such as BIM, IoT, and Digital Twins) to be used within the construction industry setting to understand and augment the learning of all practitioners. An exploratory qualitative research approach through literature review is used in the development of the conceptual framework for the implementation of H&S management that will inform future detailed developments of this proposed innovative approach
