The Gulf Cooperation Council member countries not only generate the highest quantity of municipal solid waste (MSW) per capita when compared globally, but also in most of these countries, such waste is just dumped at different landfill stations. In Oman, the total quantity of MSW stood at 2.0 million tons per year. The emission from this waste is estimated at 2,181,034 tons/year (carbon dioxide equivalent). This article attempts to develop frameworks that considered landfilling, composting and recycling of MSW.

To know the composition of the municipal solid waste in Oman, a quantitative research method was employed. The greenhouse gas (GHG) emissions from MSWM in this study focus on three major gases, CO₂, CH₄ and N₂O. The Intergovernmental Panel on Climate Change (IPCC) 2006 model is used to calculate GHG emissions from landfills and composting (IPCC, 2006). Four frameworks – baseline F0, framework F1, framework F2 and framework F3 – are outlined in this paper. The F0 represents the current situation of the MSW in which most of the waste goes to landfills and dumpsites. In F1, improved MSW collection service and landfilling are incorporated and open burning is restricted. The F2 considered landfilling and composting, while F3 is based on landfilling, composting and recycling.

The framework F2, which proposes the composting process for the organic waste which normally goes to landfills, results in the reduction of emissions by 40% as compared to landfill practice. Similarly, the samples of MSW collected in Oman show a good amount of recycling waste. The framework F3, which considers the landfill, composting and recycling, reduced the total GHG emissions from 2,181,034 tons/year to 1,427,998 tons/year (carbon dioxide equivalent), representing a total reduction of 35% in emissions.

Different values such as CH₄ correction factor, the fraction of degradable organic carbon and the fraction of DOC used to determine the GHG emissions from MSW considering landfilling, composting and recycling based on the IPPC model and existing literature review. The actual determination of these values based on the Oman conditions may result in more accurate emissions from MSW in Oman.

Different frameworks suggested in this research have different practical implications; however, the final framework F3, which produces fewer emissions, required a material recovery facility to recycle the MSW in Oman. For framework F3, it is important that the residents in Oman have enough knowledge and willingness to do the waste segregation at the household level. Apparently, such knowledge and willingness need to be determined through a separate study.

The frameworks F2 and F3 are considered to be more suitable solutions compared to the current practices for Oman and other gulf countries to reduce its per capita emissions from MSW and protect its local environment. There is a potential for further work that needs to explore the possible solutions to implement the suggested frameworks.

The use of the private sector in the provision of public services under the Private Finance Initiative (PFI) is still a relatively new concept. The structure of a project under the PFI leads to the involvement of a number of parties and this necessitates the formation of a number of different contracts to regulate the relationships. These range in complexity from the main concession contract for the funding, supply, operation and maintenance of the asset, to subcontracts between the concessionaire and the various subcontractors. As the New Engineering Contract (NEC) has been designed to provide a contracting system which stimuates good management and is sufficiently flexible to be used for all the interfaces in a complex project, it is a strong candidate for adoption at all the interfaces in a PFI project. The paper concludes that there is potential for using the different contract forms in the NEC family for a number of the different relationships under a PFI project and more specifically DBFO projects.

While discourse abounds regarding the potential impacts of sports mega events on host cities, existing ideologies about, strategies for, and systematic examinations of “legacy” effects are poorly understood. This chapter presents a sociological examination of the sport mega-event legacy measurement process.

In this chapter, we reflect on our own involvement in legacy evaluation in the context of the 2015 Pan/Parapan Am Games in Toronto to examine existing legacy measurement strategies, review their findings, and present a theoretical detour via the past for consideration in future sociological contributions to the legacy measurement process.

Data discussed in this chapter suggest a need for the creation of a more sociologically informed, methodologically robust and piecemeal rather than Utopian-oriented “report card” measurement device for legacy evaluation.

Based on the review of evidence, we contend that if sociologists of sport remain committed to keeping their roles, as public intellectuals, applied researchers or participatory activists in the sport for development/legacy nexus, those involved might do so with a greater attention to focusing on what Karl Popper (1961) refers to as piecemeal social engineering strategies and measurements, and attending to those legacies both on and off the event organizing committee radar screen.

The entry of the UK into EEC creates a community of some 250 million people. In order that they can be welded together, freedom of movement for the professions is necessary and desirable. The Rome Treaty recognises this. There is, however, a difficulty. Member countries have yet to recognise the professional qualifications of each other's nationals. Movement or, as it is termed in the Treaty, freedom of establishment, is not possible without this recognition. Recognition depends on the professional qualifications being harmonised between several countries. For 12 years the Six have grappled with the problem, largely unsuccessfully. The entry of the UK requires a new look at the 40 draft Directives issued by the Commission for the mutual recognition of qualifications. The problems which must be faced, however, are several.

Non-value adding activities (NVAAs) are considered to be problematic in the management of projects. Reported research findings suggest that these NVAAs consume resources without necessarily adding value to completed tasks. The main aim of the research is to provide insights and plausible explanations concerning how NVAAs can propagate poor performance in South Africa.

The paper reports on a quantitative survey conducted among public sector clients, consulting engineers, and civil engineering contractors in South Africa. Using a framework that was developed from the literature reviewed, the study proposed three conceptual qualitative models that were based on system dynamics.

The study suggests that NVAAs that are prevalent in South African construction can impact project performance negatively in the form of cost and time overruns. It can also be argued that although there is commonality between NVAAs that are identified in South Africa and other countries, their frequency and effects on project performance differ.

The findings provide further insights about NVAAs that are related to the South African infrastructure sector only.

The study, which is the first of such in South Africa, could lead to increased awareness among South African project stakeholders that are concerned about performance improvement from the lean construction perspective.

Past studies highlight a wide range of labour-related problems resulting in productivity loss in the construction industry of many developing countries. This study aims to quantify the impacts of labour-related factors on the productivity of construction operations in Sri Lankan building projects based on the viewpoint of engineers and construction managers for upgrading management/organisational policies and practices.

Qualitative and quantitative approaches were used to identify the critical factors. Further, a series of industry consultative discussions were conducted through problem-based communication approaches to analyse the actions required.

A total of 21 factors were determined as critical, where skills shortage, labourers’ thinking abilities, work experience, knowledge in construction works and discipline were leading in the list. The statistical tests and the experts’ discussion outcomes ensured the validity and reliability of the study findings.

The study outcomes will contribute to finding out better ways for directing labour in the industry practices and revising organisational policies towards achieving higher productivity levels in construction operations. Though the study findings are limited to the Sri Lankan context, some findings may be tested in other developing countries in similar scenarios.

The study findings show why the identified factors are critical, how those influence construction practices and what actions need to be considered for addressing the industry’s productivity-related challenges. These can play a key role in upgrading the construction management practices and organisational policies to the near-future stages.

In some regions including the Gulf Cooperation Council (GCC) region where construction is one of the main industries, the implementation of BIM is still at a slow rate. This article attempts to know the current situation of BIM and explore the challenges in the BIM implementation in the GCC construction industry.

A mixed research approach that includes a systematic literature review and a survey questionnaire was adopted to achieve the aim of this research. For the systematic review, four main databases were search considering a period of 2010–2019 to identify the main challenges in the BIM implementation. A total of 39 different challenges from 47 documents were classified into four main categories. A structured questionnaire developed on these challenges was sent to 206 selected from the top construction organizations from all over the GCC region.

A total of 39 different challenges from 47 documents were classified into four main categories. The respondents for the questionnaire were selected from the top construction organization from all over the GCC region. A large number of the respondents (69.79%) reported that their organizations are planning for BIM implementation in their future projects. The results show that top challenges fall under the main categories of “Organization”, “Technical”, “Government and Legal” and “Environment”.

While the paper provides an overview of BIM in a global context, however, the dynamics and maturity of the construction industry in different regions are quite different from each other. Since the data collected in this research is from the GCC region, the results are more relevant to the GCC region.

The finding of this research identifies the main challenges which GCC construction is facing in the implementation of BIM. The finding will, therefore, be useful for the key stakeholders to develop strategies to overcome these challenges and pave the road to take the advantages of BIM implementation in construction.

The BIM implementation in the GCC construction industry will not only improve the performance of the industry but will also open the doors for new opportunities and employment. The BIM implementation in construction will help the region to achieve Goal 9 (industrial innovation and improved infrastructure) of the United Nations Sustainable Development Goals.

The results of this study help to understand the overall situation including the challenges in the BIM implementation in the GCC construction industry. This study will be helpful for all the stakeholders to develop strategies for the effective implementation of BIM in the GCC construction industry.

This paper aims to study a dynamic post-disaster emergency planning (PDEP) problem in an integrated network through the investigation of the selection of shelters, medical centers and distribution centers (DCs), and the allocation of evacuees and injured people. The resource and people assignment in multiple periods are considered.

A mathematical formulation is provided for the PDEP problem. The authors decompose the model into two sub-models as follows: the primary model is an integer programming model and the subproblem is a nonlinear programming model with continuous variables. The simulated annealing is used to solve the primary problem, and particle swarm optimization (PSO) mixed with beetle antennae search (BAS) is used to solve the subproblem.

The paper finds that BAS can increase the stability of PSO and keep the advantages of PSO’s rapid convergence. By implementing these algorithms on emergency planning after the Wenchuan earthquake that happened in China in 2008, this paper finds that the priority of different levels of injured people is influenced by several factors. Even within the same disaster, the priority of different levels of injured can be inconsistent because of the differences in resource levels.

The authors integrate the shelters, medical centers and DCs as a system, and simultaneously, consider evacuees and injured people and different resource assignments. The authors divide the injured people into three levels and use survival rate function to simulate the survival conditions of different people. The authors provide an improved PSO algorithm to solve the problem.
