Building future scenarios using cognitive mapping

A participatory approach for developing future scenarios through cognitive maps as a visual representation of mental models is presented. Applying long-term future visioning techniques in a workshop setting has traditionally been a significant challenge for construction industry practitioners with a predominantly short-term, project-based approach to day-to-day operational responsibilities. Six future scenario cognitive maps are presented to illustrate the process. The maps were digitised from A1-sized papers using Decision Explorer software. Several key characteristics of the resulting cognitive maps and lessons learnt for the organisation of industry-based workshops are discussed. The main benefits are derived from the interaction between participants during the mapping process whereby future issues and their interconnectivities are discussed. Limitations of the findings and further work are presented

Long-Term Performance of Hybrid Anodes for Cathodic Protection of Reinforced Concrete

The long-term performance of hybrid anode corrosion protection systems (UK invention disclosed in Patent GB2426008B) was investigated on six bridge structures as part of a holistic approach to corrosion risk management, using the performance criteria in ISO BS EN 12696:2016. The aim of the study was to review the effectiveness of current design approaches to meet the residual service life when the anodes are operating in the galvanic phase. This was achieved by analysing data on the general condition of the structures, the ongoing performance of the installed hybrid anodes, and assessing the subsequent corrosion risk. It was found that the six structures were generally in good condition, 1 to 8 years after refurbishment works, with low associated corrosion risk in areas protected by the hybrid anode systems. This is a positive finding for the wider implementation of hybrid anode systems as an alternative corrosion management technique. The reinforcement in the protected areas remained predominately in a passive condition, with calculated corrosion rates below the ISO 12696:2016 recommended threshold of 2mA/m2

The futures of construction: a critical review of construction future studies

Anticipating the future is increasingly being seen as a useful way to align, direct and improve current organizational strategy. Several such 'future studies' have been produced which envision various construction industry scenarios which result from technological and socio-economic trends and influences. Thirteen construction-related future studies are critically reviewed. Most studies fail to address the complexities and uncertainties of both the present and the future, and fail to explore the connections between global, local, construction-specific and more widespread factors. The methodological approaches used in these studies do not generate any significantly different advice or recommendations for the industry than those emerging from the much larger canon of non-future oriented construction research. As such, these reports are less about the future than the present. If future studies are to make a worthwhile contribution to construction, it is critical that they develop our appreciation of the practical ability of stakeholders to influence some aspects of the future and not others, and an awareness of the competing agendas and the relative benefits and disadvantages of specific futures within the construction sector. Only then can future studies provide insights and help in preparing for the opportunities and threats the future may bring.Future studies, scenarios, construction,
