Constructability obstacles: an exploratory factor analysis approach

Constructability is a concept with relative and not absolute value to increase optimization capacity of resources such as workforce, time, cost, quality, and working environment conditions. Given the growing complexity of projects and the increased number of failed and abandoned projects, the necessity to implement constructability in projects has become more tangible. Although the effects of lack of quantitative definition of constructability role in the traditional construction approaches are evident and have led to lack of coordination in performance of construction projects, so far no comprehensive quantitative approach has been considered to analyze the obstacles to constructability implementation. This study aims to identify and categorize the obstacles to facilitating the presence of contractors in the early stages of planning and design to implement constructability. In this study a comprehensive list of obstacles to constructability implementation is developed as a questionnaire. This questionnaire was presented to the experts, active in the field of construction. Finally, its results were analyzed using exploratory factor analysis method. Totally, 63 obstacles were questioned, then they were categorized by some of the experts of this industry into five categories of macro factors, including contractual, environmental, managerial, technical, and organizational. The significance of this study is due to this fact that identifying and categorizing the key obstacles to constructability implementation provides a useful reference for managers and owners of the construction industry to identify and develop solutions to resolve them. Identifying the obstacles to the presence of contractors in the planning and design stage and having a quantitative view toward this issue affects project implementability. In this regard, one can present more effective solutions to facilitate the presence of contractors in the early stages of design and also improves the effectiveness of constructability.Constructability is a concept with relative and not absolute value to increase optimization capacity of resources such as workforce, time, cost, quality, and working environment conditions.

Comparison of Feed in Tariff, Quota and Auction Mechanisms to Support Wind Power Development

A comparison of policy instruments employed to support onshore wind projects suggests that in terms of capacity installed, policies adopted in Germany have been more effective than those adopted in the UK. Price comparisons have frequently neglected differences in resource base: once accounted for we find the cost of policies to be similar. A developer survey identifies planning constraints as only one reason why installed capacity is greater in Germany, and indicates that price support is also important. Information provided by developers also suggests that although the tendering process adopted in the UK is highly competitive in terms of price paid for energy delivered, competition in other areas of the market is significantly lower than in Germany

Strengthening transfers and transitions: sustaining improvement, building capacity (National Strategies)

"This report highlights that sustainable partnership work between LAs and schools can accelerate pupil progress and that Transfer and Transitions are key drivers for raising standards. It describes how things have been taken forward in LAs and schools, and explores what has continued to have impact and how this has been achieved. It identifies significant elements for success and explains how they work in combination to build capacity for ongoing improvement." - National Strategies website

Natural hazards and disaster management in Pakistan

The present study explains the various concepts used in disaster management. The concepts explained include: Disaster, Hazard, Vulnerability, Capacity, Risk and Disaster Management Cycle. In addition to the terminologies, the study also seeks to explain various types of disasters. It also gives a detail of various disasters occurred in Pakistan as well their management and mitigation strategies. The paper also discusses disaster management policy at national level as well as disaster management and national plans in Pakistan

Building Disaster Resilience within the Emirati Energy Sector through a Comprehensive Strategic Mitigation Plan

Disasters, both natural and man-made, have been occurring with increasing frequency and effect in recent decades in many countries around the world. Such threats have been shown to result in a loss of life, property and income and all of which have an impact on the country’s socio-economic structure and geo-political positioning. The UAE is steadily adapting its policies and practices to manage any potential disaster, whether natural or man-made. However, evidently the UAE is exposed and vulnerable to tectonic activity from a number of sources and yet there is little in the form of seismic detection, protection, resistance or design for some of the newest and tallest structures in the world. The paper highlights the importance of the strategic mitigation planning for disaster resilience within the Emirati Energy sector. It discusses the issue of disaster globally and then specifically with regards to the UAE, forming a critical analysis on crisis and its management. A broad literature review of the problems readily associated within the discourse is undertaken so that the definition, classification and the application of the disaster and its management cycle are appropriately contextualised in regards to the Emirati problem. The window of opportunity that the UAE has for improvement is emphasised by the findings of this paper
