“…In addition, globally, buildings could consume 16% of the water and indirectly produce nearly 70% of all sulfur oxides [6]. The pressures of sustainable development in the building and construction sectors have become an emerging issue across the world and include the improvement of construction practices and green innovations, such as ecological construction, green building, recycling and eco building materials, in order to minimize their environmental impacts [7][8][9][10][11][12][13]. However, the building and construction industries have been blamed for issues in technological innovations, quality and sustainability with inadequate market competition and governmental policies.…”

Project-Based Market Competition and Policy Implications for Sustainable Developments in Building and Construction Sectors

Building and construction sectors are significant contributors to the global economy, but their energy consumption necessitates greater commitment to sustainable developments. There is therefore a growing demand for green innovation in the form of cleaner production and policies to meet the modern requirements of sustainability. However, the nature in which public work is undertaken is in an environment of project-based market competition, whereby contractors routinely bid for contracts under specific project awarding systems, and variations are accompanied with the unique scope of individual projects before the final goods or services are delivered. A comprehensive understanding of the characteristics and contractors' behavior in systems could help to identify the leverage points of policies. This paper proposes a system dynamics model, with quantitative analysis and simulations, to demonstrate the problems of a system with different project awarding systems and ineffective market performance. The framework of market efficiency and performance measures has been proposed to evaluate the project-based competition mechanism. Managerial policy implications for market efficiency and sustainable developments can thus be systematically discussed and compared through iterative computer simulations and scenario analysis.

“…From the literature, it was found that there are many sustainability reporting tools (SRTs) available in the market to gauge the level of sustainability of buildings/infrastructure (Cole, 1999;Crawley and Aho, 1999;Siew et al, 2013;Siew, 2014aSiew, , 2014b. The use of SRTs demonstrates the commitment of building owners and operators towards their environmental responsibility and permits staying ahead of future regulations.…”

“…The use of SRTs demonstrates the commitment of building owners and operators towards their environmental responsibility and permits staying ahead of future regulations. Cole (1999) argues that the definition of building performance varies according the different interest of parties involved in building development. For example, a building owner would perceive the performance of a building from a cost efficiency perspective whereas occupants will be more concerned about indoor air quality, comfort, health and safety issues.…”

Optimal bid model for construction contracts

Construction clients are increasingly calling for bids that require contractors to submit both bid price and highlight sustainability attributes. Contractors are faced with the problem of deciding which combination of bid price and sustainability attributes to submit. An important consideration is the cost of sustainability attributes to the client. This varies between contracts and types of projects. This paper proposes the use of a sustainability unit value which the client can use as a basis for determining the contractor's total combined bid. This kind of procurement method is traditionally known as the A+B method. To illustrate the mechanism of price-sustainability attribute bi-parameter procurement, a total combined ISO-map is developed. The contractor's price-sustainability performance curve is then incorporated into the map to determine the contractor's optimal bid parameters: tender price and sustainability performance. A mathematical optimisation bid model is developed for calculating the optimal bid parameters.

“…For example, weightings should not be based on whether air pollution is more important than land pollution but instead on which of these aspect exerts a greater specific potential impact on the environment as a point of concern. As the relationships between buildings/building components and their associated sustainability impacts keep advancing through research and requisite data collection, it will become possible to establish reliable guides to assist users to apply weighting protocols to assessment criteria and to meaningfully interpret aggregated results [73].…”

The provision of Application Programming Interface (API) in BIM-enable tools can contribute to facilitating BIM-related research. APIs are useful links for running plug-ins and external programmes but they are yet to be fully exploited in expanding the BIM scope. The modelling of n-Dimensional (nD) building performance measures can potentially benefit from BIM extension through API implementations. Sustainability is one such measure associated with buildings. For the structural engineer, recent design criteria have put great emphasis on the sustainability credentials as part of the traditional criteria of structural integrity, constructability and cost. This paper examines the utilization of API in BIM extension and presents a demonstration of an API application to embed sustainability issues into the appraisal process of structural conceptual design options in BIM. It concludes that API implementations are useful in expanding the BIM scope. Also, the approach including process modelling, algorithms and object-based instantiations demonstrated in the API implementation can be applicable to other nD building performance measures as may be relevant to the various professional platforms in the construction domain.
