“…This is a good example of a method to estimate the costs and benefits associated with different design concepts. A similar evaluation was applied in Sweden in the doctoral thesis of Karim (Karim and Magnusson, 2008) using Life-Cycle Costs (LCC). Similar approaches may be applied in other countries but no other published articles could be obtained in this review.…”

Abstract"SAVeRS" (Selection of Appropriate Vehicle Restraint Systems) is a project funded within the CEDR 2012 Transnational Road Research Programme "Safety". The first Work Package of the project is aimed at analysing the existing criteria for identifying the need for the placement of a vehicle restraint system and for the identification of the most appropriate performance class. For this aim both the existing national standards and guidelines and literature documents have been analysed in details. The comparative analysis of 33 national standards and guidelines covering most of Europe and several non-European Countries has shown that there are many commonalities and it is possible to identify the most frequently used parameters with reference to safety barriers. Whilst the majority of the countries have guidelines and/or standards related to safety barriers, there is generally limited guidance for other systems such as crash cushions, transitions and motorcycle protection systems. Life-cycle cost models are usually not included in the standards but few tools are available worldwide.Keywords: Roadside safety; safety barriers; crash cushions; terminals; transitions. Résumé"SAVeRS" (Sélection de systèmes de retenue approprié) est un projet financé dans le CEDR 2012 transnationale Road Research Programme "Sécurité". Le premier lot de travaux du projet vise à analyser les critères existants pour déterminer la nécessité de la mise en place d'un système de retenue du véhicule et pour l'identification de la classe de performance le plus approprié. Pour cet objectif les documents relatifs à la fois à la norme nationale et les lignes directrices ainsi que la littérature ont été analysés en détail. L'analyse comparative des 33 normes et directives nationales couvrant la majeure partie de l'Europe et plusieurs pays non européens a montré qu'il existe beaucoup de points communs et qu'il est possible d' identifier les paramètres les plus fréquemment utilisés en référence à des barrières de sécurité . Alors que la majorité des pays ont des directives et/ou normes relatives aux barrières de sécurité, il existe généralement peu d'indications pour d'autres systèmes tels que les atténuateurs de choc, les transitions et les systèmes de protection de moto. Les modèles de coûts du cycle de vie ne sont généralement pas inclus dans les normes, mais peu d'outils sont disponibles dans le monde entier.

The construction industry is often ranked top in producing the largest amount of waste during a project, be it the waste of material resources or the waste of manpower. This has elevated the need for an improved and more structured management technique. This study will look into the principles and practices of lean management pertinent to highway construction projects to analyze whether lean management practices can improve the management efficiency for complex projects. This study adopted a quantitative approach, and a linear regression model has been used to investigate correlations between the lean test factors and the efficiency-dependent variables. It was found that lean management tools that are used repeatedly and the ones that require a high level of detailing are positively associated with efficiency improvement in highway construction projects. In particular, LPS, JIT, and VM were found to be more commonly used in highway construction projects. The research results will aid in the initial decision-making process of the project managers, as they will be able to map different lean tools with their benefits and limitations and then select the one that best suits the project needs and deliverables. Future studies can adopt the interpretivism paradigm to explore new theories and concepts related to highway construction management.

“…Researchers of these studies have referred to minimizing problems, reducing conflicts, decreasing costs, optimal using of experiences and knowledge of people in the construction stage, reducing changes in the project construction time, improving effectiveness of teamwork, increasing integration among different stages of the project, and many other factors as the benefits of applying this concept (Alinaitwe et al, 2014;Dunston et al, 2007;TDT, 2016;Al-Otaibi et al, 2013). Karim and Magnusson (2008), Dunston (2007), Meier (2000), Karim (2010), D. Silva (2004) consider reducing the risks, increasing knowledge of people, documenting information, reducing costs and time of the project as other benefits of applying operation and maintenance concepts. However, a few researchers have studied these three concepts in an integrated way.…”

Despite allocating huge budgets to civil engineering projects, detailed planning, and employing human resources, project managers still face time, cost, and quality constraints. Most of these challenges are due to a lack of integration of different project phases and the limitations of the presence of construction and maintenance contractors in the initial stages of the project. Considering the benefits of applying constructability, operability, and maintainability (COM) concepts, many problems caused by lack of coordination, or duplications and weakness in management, and also time and extra costs due to lack of presence of construction and maintenance contractors in the early stages of the project are resolvable. In this regard, various studies have investigated the benefits of applying these concepts; however, there has been no comprehensive analysis of the benefits of COM. As a result of focus on the benefits of implementation of these concepts and evaluating the effect of each of these strategies and benefits, from different perspectives during various time periods, managers can increase project efficiency and productivity, and improve their performance, through using concepts and strategies of their implementation. This research aims to evaluate the trend of studies on the benefits of implementing constructability, operability, and maintainability in the construction industry. For that, the in-depth literature review method is applied. For qualitative analysis of the obtained information, descriptive analysis has been used. Then, the data was coded, and classified using Excel Software for quantitative data analysis. Finally, the charts presented were evaluated according to the classified fields of study. The necessity of performing such a study is significant because of the fact that a large share of a project's problems, such as lack of plans' integration and weakness of administrative system, and increasing time and cost, are due to lack of exchange of information and ineffective relationship between the design people and the construction and maintenance stakeholders, and ignoring the effects of design decisions on constructability and operability and maintainability implementation.
