A Framework for Utilising Lean Construction Strategies to Promote Safety on Construction SitesThe poor safety situation in the United Kingdom (UK) construction industry and its adverse socio-economic record are well documented in the existing literature. The application of Lean Construction techniques has been proposed as an effective strategy to address accidents on construction sites, a major safety concern in the construction industry. However, examination of the relationship between Lean Construction techniques and safety issues has been marginal. This study explores this relationship with the aim of developing a framework for using Lean Construction techniques to promote safety on UK construction sites. A framework was initially devised based on a synthesis of the literature and further refined based on findings from interviews held with 10 Lean Construction practitioners on antecedents of Lean Construction techniques and safety issues. In order to develop and confirm the framework, data was collected from practicing Lean Construction organisations using a questionnaire survey and analysed using descriptive statistics, inferential statistics and inter-rater agreement statistical test to examine the pattern and extent of the relationships. The study found a total of thirty-eight (38) relationships between Lean Construction techniques and safety issues. These relationships are mainly positive in nature in that they demonstrate path to improvement in safety on construction sites. They show which techniques could be used to address the relevant safety issue. Furthermore, it was established that the application of Lean Construction techniques on construction sites can be impeded by challenges such as: lack of Lean Construction knowledge, complexity, misconception about Lean and difficulties in changing employees’ working culture. The study identified strategies that could be used to address these challenges. These include enlightenment on benefits of Lean practice, publication of improvements realised from Lean practice, training, workers’ involvement and empowerment, persistence, robust planning and gradual step-by-step implementation. The study, therefore, concludes that Lean Construction techniques have positive relationships with safety issues on construction sites in the UK and on the basis of the relationships develops an integrated framework to guide application of the techniques by contracting organisations in promoting safety. The study makes a number of recommendations including the incorporation of Lean Construction practice into government health and safety initiatives, regulations and policies, and identifies areas for further research.

AN INVESTIGATION INTO THE IMPLEMENTATION OF THE CONSTRUCTION (DESIGN AND MANAGEMENT) REGULATIONS IN THE CONSTRUCTION INDUSTRYThe European Union (EU), in 1992, issued the Temporary or Mobile Construction Sites (TMCS) Directive, which requires EU members to introduce specific law to improve health and safety (H&S) performance outcomes by placing specific duties on key stakeholders. This Directive led to the introduction of the first Construction (Design and Management) (CDM) Regulations in the UK construction industry on 31 March 1995 and since their introduction, the overall performance of construction H&S has improved gradually. However, despite this positive outlook, there are still significant concerns surrounding the implementation of the CDM Regulations, a subject on which empirical research has been very scanty. It is against such a background that this study investigates the practical implementation of the CDM Regulations and extends current knowledge and understanding, and develops a framework for appropriate remedial action by industry. The research method involved a thorough critical review of literature, semi-structured interviews, and two postal questionnaire surveys, using as research informants, practitioners with experience of the Designer, CDM Coordinator (CDM-C), and Principal Contractor (PC) roles under the CDM Regulations. Primary data were collected and analysed from in-depth interviews with six organisations purposively selected based on their construction design expertise and 122 questionnaires returned in total. The finding regarding lack of collaborative working amongst duty holders is a significant outcome of this study; a requirement expressed explicitly within the CDM Regulations, yet questionable in terms of its implementation. Further, the study reveals a number of statistically significant correlations between the extent of discharge of duties and their perceived degree of importance. However, the strength of the majority of these correlations is weak. In particular, the evidence indicates that 50% of the duties of the CDM-C are misaligned in terms of extent of discharge and perceived degree of importance, whereas 25% of the PC duties are also misaligned. This signals a lack of understanding regarding the importance of duties, towards achieving improved H&S management. Surprisingly, a comparison between extent of discharge of duties and their perceived degree of difficulty reveals that all the duties of the PC are statistically significant, meaning that the perceived degree of difficulty does not impede their extent of discharge. While 90% of the CDM-C duties are also statistically significant, again the same interpretation applies. Further, a consensus reached by Designers supports the view that CDM-Cs provide insufficient input throughout the planning and construction phase, raising doubt as to whether the duty holder is fit for purpose. Overall, the results confirm that interdependent working of duty holders is still a challenge, demonstrated by the Designer duty to ensure appointment of the CDM-C (Regulation 18(1)), the CDM-C duty to ensure Designers comply with their duties (Regulation 20(2)(c)), and the PC duty to liaise with the CDM-C and Designer (Regulation 22(1)(b)). Three recurring themes emerge from the results, that is: (i) collaboration, (ii) accountability and compliance, and (iii) facilitation, which in turn inform the remedial action framework comprising 13 remedial actions and 8 change drivers. Validation of the remedial action framework by 15 study participants reveals that, at least 10 remedial actions and 7 change drivers are considered likely to improve CDM implementation. The top three remedial actions are: (i) ensuring adequate arrangements for coordination of H&S measures; (ii) including provisions within the regulations specifying the stages for the appointment of duty holders; and (iii) amending the ACoP to provide guidance on determining what resources are adequate for a particular project. Whereas, the top three change drivers are: (i) management leadership; (ii) the proactive participation of duty holders; and (iii) training to equip duty holders with sufficient knowledge on provision of timely and adequate preconstruction information. Based on these outcomes, conclusions, recommendations, and further areas of research are drawn.

An investigation into the different styles of the lawyer and construction specialist when mediating construction disputesPurpose The purpose of this paper is to assess the views and experiences of mediators from different professional backgrounds practising in the construction industry. Previous research shows that the legal profession dominates construction mediation in both England and Wales. Design/methodology/approach The phenomenological approach was used to capture the lived experiences of the interviewees and gain insight into their views and practices. The data collection was by semi-structured interviews. The data was then analysed using software to establish themes. Findings The major difference in mediator practice discovered between the two groups is the use of the evaluative style by lawyer and facilitative style by non-lawyer mediators. Non-lawyer mediators strongly reported their criticisms of the evaluative style in mediation suggesting that it undermines the parties’ ability to self-determine their own dispute and reduces the level of satisfaction experienced by the parties in the process of mediation. Lawyer mediators supported the use of the evaluative style as an acceptable compromise on the parties’ self-determination and feelings of satisfaction in pursuit of achieving the goal of a settlement in mediation, which was significantly better than the escalation of stress and costs to the parties in the event that the dispute escalates to litigation. In addition, mandatory mediation, the role of advisors/advocates, governance and the future of mediation were explored. Originality/value The research is anticipated to be of particular benefit to parties considering referring a construction dispute to mediation.
