Freeways typify accessibility, which is a parameter related to the development of a country. A developing country, such as Mexico, is concerned with an emergent construction market of freeways, which has been a target for Portuguese construction companies since the Portuguese economic and construction crisis in 2008.In the earlier stages of a freeway project, the ubiquitous use of software calculations along with geometric standards restrictions is performed automatically and may introduce loss of sensitivity to the designer.This paper addresses this concern by presenting a Standards comparison between Mexico and Portugal, focusing on the elements of design and a comparative multi-criteria analysis adapted from Kalamaras et al. (2000). Through six case studies, this paper analyses the Standards’ influence on the horizontal alignment outcome, the radial uncompensated accelerations and the Brückner curves, concluding with the multi-criteria analysis results.

ABSTRACTThis article addresses a range of conceptual issues relating to the history of European port cities in order to construct a framework for comparative research. Port cities played a key role in European urban development and their growth was often determined by common factors. Particular attention is paid to the demography of port cities, their specific labour markets and the dominant ideology of merchant capital. The article establishes a basis for analysing case studies of individual port cities and for exploring their location within the overall process of European urbanization.

This study assessed the levels of risk that contractors may be subject to while executing a GMP contract by applying a collar option model to the case study of an apartment project in Korea and identified implications for the application of GMP contracts in Korea. The payoff structure of the GMP contract was defined based on the collar option model and a profit sharing ratio calculated to evaluate the risks involved in GMP contracts. The results showed that an increase in the GMP and a decrease in the expected cost and cost range were accompanied by a decrease in the profit sharing ratio. The proposed valuation model for GMP contracts is expected to help clients and contractors in Korea negotiate reasonable contracts as it enables the contractor to utilize the proposed model as basic data, the client to evaluate the performance of the contractor, and both parties to agree a reasonable profit sharing ratio. Implementing GMP contracts with CMR is likely to have a number of positive effects on the Korean construction market. However, in order to maximize these effects, it is necessary to have the ability to evaluate cost uncertainty. Accordingly, it is very important to analyze the factors that influence cost volatility. In future work, the various factors that have an impact on the GMP must be studied to maximize the positive effects of the framework proposed in this paper. An analysis of the effect of each factor on the change in the GMP will help Korean construction companies who are attempting to introduce GMP contracts to perform their preconstruction services effectively.

<p>This paper aimed to investigate the up-to-date levels of sustainability in the UK construction with special interest to sustainable housing. It also aims to examine the justification behind construction and housing sustainability, and to look at the practicality of transferring current expertise within the UK as well as to an emerging Central Asian country such as Kazakhstan. A synergy of case studies, survey and numerical simulation research methodologies were applied to undertake a wide-spectrum analysis of the topic. Regardless of difficulties related to applying sustainable practices the considered housing developments are found to be satisfactory in terms of environmental and socio-economic effects. Technical evaluation of the case studies compared to standard housing parameters has shown encouraging outcomes and confirmed the claimed energy and water efficiency. Findings of the survey indicated that construction companies of the UK and Kazakhstan are at different stages of application of sustainability measures. It was also established that companies and public are mainly optimistic about sustainability if suitable economical and legal conditions are ensured. Finally, numerical simulations have shown that selected sustainability measures made the studied housing projects competitive on the sustainability market. </p>

Regional logistics changes. Locational dynamics and strategies in physical distribution - a transatlantic comparison. The paper discusses locational dynamics of freight distribution firms at the regional level, as a consequence of changes in logistics network configuration and related requirements for placing distribution centres. The empirical basis is provided by two case studies, carried out in Germany and in Northern California (USA). Both cases are subject to comparative analysis, regarding location choice and context, corporate strategy and regional policy and planning.

Construction market in Korea has been decreased for 3 or 4 years, and it brought the problem in supply and demand of workforce. Therefore, new workforce in construction industry could not been enter, and some of them have been employed in non-major area. This research intends to analyze construction industry as well as demand and status of construction companies and to diagnose status of new workforce for architectural works, and a survey is conducted for enrolled students and graduates to diagnose problems of current status in order to suggest the alternatives in Korea.

Housing is one of the most important needs of mankind to survive. A secure and properly planned house, gives comfort to people using it, keeping them secure from severe environment, un-wanted people and animals. Apart from the human casualties, the other striking and usually most visible effect of natural disaster is majorly the destruction of houses. The loss of houses has a devastating effect on privacy, livelihoods and the dignity of individuals. An effective program for the reconstruction of houses for those affected is critical to ensure restoration of the society’s economy, cultural identity and dignity. For many humanitarian organizations, employing professional construction companies is the most common and quickest way of rebuilding houses in the aftermath of a disaster. However every strategy has its own risks and limitations, but there is a growing awareness being shared among countries to mitigate these situations. This study carefully examines the reconstruction strategies employed in earthquake affected buildings of Kashmir, Pakistan and Gujrat, India. The analysis concludes proper fulfillment of the bye laws for seismic resistant construction and enforcing law of training for laborers and local people in redevelopment of earthquake hit area.
