This paper critically reviews economic impact assessment methods adopted in construction-related projects, to develop and present a novel bottom-up approach suitable to estimate regional economic impacts of building maintenance projects.

A thorough literature review of economic impact assessment in construction projects is carried out to identify the most relevant approach to estimate wider economic impacts of building maintenance projects. Based on these findings, a model based on the bottom-up approach to estimate wider economic impacts is developed. The applicability and face validity of the developed model is demonstrated through a case of cladding replacement program in Australia.

The literature review revealed that bottom-up models are better suited for estimating regional economic impacts of maintenance projects, given the challenges of obtaining micro-level economic data in the maintenance sector. In relation to the total economic impacts (direct and indirect), the results show that for every $1 of government spending on similar projects the Gross State Product would increase by $1.34. In terms of employment impact, over 70% of the direct economic value addition is driven by the increase in labour, where close to 3 FTE jobs will be required for each $1 million of spending on cladding replacement projects.

This paper presents a model to estimate the wider economic impacts of building maintenance projects, which is typically overlooked in the construction management field. The proposed model is developed to incorporate the variability of different building maintenance projects so that the economic impact resulting from these projects could be estimated more accurately. This model can be used by local government decision-makers to justify and prioritise maintenance projects in a similar manner to new construction projects.

The utilisation of products with recycled content (PwRC) in construction projects has been identified as a targeted way to achieve sustainable management of construction and demolition waste resources. However, sustainable applications of these resources are subject to a wide array of factors that demand a thorough investigation. This study, therefore, explores the motivations, barriers and strategies for optimal PwRC uptake using a multiple-case study approach.

This study adopted an interpretive multiple-case study approach. The case studies were selected from recently completed construction projects including two infrastructure projects, one commercial project and one residential project. A series of semi-structured interviews were carried out to collect the data. For each case study, four participants were interviewed; these participants represented design, client, supply and building teams.

The study revealed the main barriers, motivations and opportunities for adoption of PwRC resources in four construction projects. These factors are believed to influence the utilisation of PwRC to varying extents and/or in diverse ways. The findings also suggest that there is a significant opportunity for stakeholders to adopt more sustainable waste management practices, and the use of institutional drivers can help achieve this goal.

The primary research contribution of the study lies in proposing three key research directions: investigating regulatory constraints impacting the use of PwRC, addressing supply chain challenges and enhancing quality assurance.

The research has a practical contribution to the industry through a suite of actionable strategies to increase the uptake of PwRC. The strategies are mostly focussed on stakeholders' education, the regulation that supports PwRC and project management planning. The two major motivations – referring to two of the three pillars of sustainability (economy and environment) – provide a basis for organisational changes to ensure achieving sustainability in construction activities.

The purpose of this paper is to examine whether trust in management mediates the relationships between two types of leadership (transactional and transformational) and acceptance of change in the Hong Kong public sector.

Data from 68 civil servants in the Hong Kong SAR Government were used in the partial least squares analysis.

The findings from civil servants show that although trust in management mediates the relationship between both types of leadership and acceptance of change, transformational leadership is more effective in increasing both trust and acceptance of change.

The strong support for the mediation hypotheses highlights the need for leaders to be trusted by their followers if followers are to accept and support the change process. Trust in management is what ultimately reduces resistance to change.

The findings from this study have demonstrated that one strategy available to leaders in the Hong Kong public sector is to concentrate on developing perceptions of trustworthiness by utilising both transactional leadership and transformational leadership but especially transformational leadership.

This paper provides a unique and nuanced view of leadership and trust, and their effect on the acceptance of change in Hong Kong’s civil service bureau that operates in a turbulent environment. Public sector organisations in Hong Kong are unique in that they contend with pressures from Hong Kong nationals and also with pressures from the Government of Mainland China.

In an attempt to create national harmonisation of legislation, a set of model Work Health and Safety (WHS) Regulations were developed in Australia. These regulations require principal contractors to undertake specific WHS planning and coordination activities if the construction works to be completed cost AU $250,000 or more. However, there are some doubts about the usefulness of this monetary threshold. This study aimed to investigate how effective this threshold can be in Australia.

To evaluate the performance and operation of this threshold in the Australian construction industry, this study modelled the costs of construction for four construction project scenarios – small classroom, two-storey home renovation with adjacent pool, small commercial warehouse and single-storey house (volume home builder) – under various conditions based on historical data (2011–2017) and in eight Australian jurisdictions.

Among the six study factors (i.e. the types for construction, geographical location, design specification, delivery method, contracting approach and inflation), the research found considerable variation in the operation and performance of the monetary threshold.

The research highlights some potential challenges associated with the use of a monetary threshold in the regulation of WHS planning in construction projects. Thus, the results are expected to contribute to addressing these challenges, leading to the development of an appropriate balance to achieve efficient and effective WHS regulation in Australia.

Current understandings of innovation in construction portray it as linear, deterministic phenomena centered around novel objects and technologies deployed in sequentially-organized supply chains. This study aims to develop an enriched understanding of construction innovation as non-linear, socio-material and dynamic phenomena in complex networks by formulating a novel conceptual apparatus of complex adaptive supply networks (CASNs) expanded through actor-network theory (ANT) concepts.

This combined CASN/ANT apparatus is mobilized in the context of a qualitative case study involving a housing construction supply network in Australia making use of offsite manufacturing (OSM) techniques.

The study shows that innovative technologies such as novel OSM products can play an important though not necessarily deterministic role in the evolution of CASNs. The study also explicates the process by which the enrollment of non-human agents and the resulting CASN evolution are linked: innovative technologies shape human and non-human interactions in ways that redefine task delegation, role definition and schemas that are fundamental to the shape of CASNs.

Findings provide a compelling empirical basis for arguing that CASNs must be conceptualized as heterogeneous systems and that innovation in construction must be understood as non-linear, socio-material and dynamic, rather than linear and driven by technological determinism. The study also interrogates limiting notions of supply chains and supports the notion of alternative inter-organizational forms to understand construction project work.

The purpose of this paper is to examine the use of bid information, including both price and non‐price factors in predicting the bidder's performance.

The practice of the industry was first reviewed. Data on bid evaluation and performance records of the successful bids were then obtained from the Hong Kong Housing Department, the largest housing provider in Hong Kong. This was followed by the development of a radial basis function (RBF) neural network based performance prediction model.

It is found that public clients are more conscientious and include non‐price factors in their bid evaluation equations. With the input variables used the information is available at the time of the bid and the output variable is the project performance score recorded during work in progress achieved by the successful bidder. It was found that past project performance score is the most sensitive input variable in predicting future performance.

The paper shows the inadequacy of using price alone for bid award criterion. The need for a systemic performance evaluation is also highlighted, as this information is highly instrumental for subsequent bid evaluations. The caveat for this study is that the prediction model was developed based on data obtained from one single source.

The value of the paper is in the use of an RBF neural network as the prediction tool because it can model non‐linear function. This capability avoids tedious “trial and error” in deciding the number of hidden layers to be used in the network model.

China’s economy is transforming at a brisk pace. A partially dismantled command economy and introduction of competition have fueled consumer demand for a greater selection of innovative new products in the retail market. The challenge for retail buyers is to adjust their procurement processes to respond to consumer needs in an efficient and effective manner. This study examines factors influencing buyer‐supplier relationships in a transition economy. We present a model to explain the factors driving retail buyer dependence on suppliers. We find that retailer evaluation of supplier credibility mediates the relationship between retailer perceptions of a supplier ability to add value to its business and the ability to achieve its desired goals. In part, this is due to the supplier’s market orientation. Interestingly, guanxi ties have no impact on the retailer perceptions of the supplier credibility, but have a positive affect on retailer dependence on its supplier partners.

This paper aims to explore the need for organizations to adopt organizational development (OD) programs on a continuous basis as a way of coping with a changing business environment. Emphasis is to be laid on organizational learning due to its significance in enhancing organizational change and development.

The paper is based on an extensive literature review.

A wide range of organizational development (OD) intervention strategies exists. There is a need to adopt a coordinated approach in applying OD efforts for organizations to reap maximum benefits.

This paper is theoretical and is not based on empirical findings.

Several recommendations are included in the paper. It is envisaged that adoption of the recommendations can assist an organization to achieve a sustainable competitive advantage.

The paper identifies several OD frameworks that can be tested in future research projects.

This study aims to increase awareness and educate the reader about health-care fraud targeting seniors in the USA to help stakeholders better understand, recognize and prevent this type of fraud.

This paper collects statistics on the current state of health care frauds committed against seniors, and examines related cases and laws.

The authors find this type of fraud is highly prevalent and expected to increase. Current laws preventing this fraud from occurring are multifold and complex. While prevention strategies through law enforcement have been somewhat successful, a reduction in resources may put seniors at an increased risk in the years to come.

Without additional prevention strategies, the problem will likely escalate with a growing population of older adults. This study encourages further research into effective prevention strategies and methods to fight health-care fraud against seniors.

Health-care fraud and its associated costs pose a significant threat to the society and economy of the USA. Reducing this fraud will not only reduce the costs to the US economy but also improve the physical and mental well-being of senior victims, reduce their mortality and hospitalization rates and improve the public trust placed to health-care providers.

This study highlights how health-care fraud is committed against seniors. With the projected trend of an aging US population, educating stakeholders, increasing awareness and applying tools to protect seniors will be important to reduce the absolute scope of this problem in the future.
