AbstractThe goal of the article is the diagnosis and presentation of the problems of the selection of construction technologies for buildings being built in the centres of urban agglomerations. The survey and literature studies that were performed show that the process of selecting these technologies is difficult due to a series of very different difficulties associated with constructing a structure in a city centre and which are sometimes hard to foresee. At the same time there is a lack of decision-making support tools dedicated to the selection of construction technologies that would take into account the problems that occur during the construction of buildings in city centres. The study shows the need to discuss the subject of developing a mathematical model and a decisionmaking support tool based on said model to that end.

Abstract The process of constructing structures and the selection of technology is difficult due to a series of highly varied conditions - which are often difficult to foresee - associated with the construction of a building within a city centre. The goal of the article is the performance of a structural analysis of the most commonly occurring conditions that need to be considered in the context of the selection of a technology of constructing buildings in the centre of an urban agglomeration. Based on a literature study that had been performed, aswell as on a survey study performed on expects, the authors listed and characterised conditions that occur during the construction of structures in the centres of urban agglomerations. Afterwards, experts determined the impact of these factors and their mutual relations in the context of the selection of the technology of the construction of said structures. In order to determine the involvement and the role of the factors in the context of the selection of a technology of the construction of a structure, as well as its analysis, the authors used the WINGS (Weighted Influence Non-linear Gauge System) modelling and structural analysis method. This method takes into account both direct, as well as indirect relations between these factors. The study contained in the article constitutes a basis for the development of a comprehensive systemic approach supporting the decision-making process associated with the selection of a construction technology for a building to be built in the centre of an urban agglomeration.

Numerous alternatives exist for foundation systems and construction technologies. The systems can be described by different criteria values which are incorporated in the conventional design process. Decision on the most suitable construction technology is vital for success and depends on many effectiveness criteria. The business success depends on the right choice. The mandate of a construction management researcher is to use rational, systematic, science-based techniques to inform and improve various decisions. The paper presents multiple criteria decision making model for selection of a pile-column technology. The technological criteria are determined by an experimental study. Based on in-situ investigation of natural soil conditions, criteria values are determined. The decision making model incorporates five different methods and techniques. To solve a problem, it uses three multiple criteria decision making methods. Integrated criteria weights are determined by using the analytic hierarchy process and the expert judgement method. This model could be used to solve complicated problems pertaining to the selection of a construction technology.

Decision making is one of the primary functions of management. Making strategic decisions are important to achieve organisational efficiency and effectiveness. In the selection of projects, it is necessary for organisations to prioritise their projects due to limited resources. Therefore, the selection of projects that bring value and substantial impact on the organisation is very important to ensure that they can compete in the dynamic external environment and meet the goals and objectives. From the case study, the result suggests that the Analytical Hierarchy Process (AHP) method can contribute significantly to the identification of sources that need further clarification of attributes and criteria and at the same time it can provide a systematic analytical tool in making a group decision. This method allows the organisation to prioritize its projects based on certain criteria as it is a quantitative decision support tool. In conclusion, AHP is the best and efficient method for decision makers to consider all facts, weigh the pluses and minuses, reach, reevaluate and communicate their decisions.

Abstract The highway project has a significant challenge in carrying out its work. The procurement of massive and constant materials is a significant problem. There are problems in basecamp selection: high transportation costs due to the distance to the raw material from the quarry, and on a managerial level, selection of basecamp location is the basis for construction firm management in controlling costs, time, and quality of the project. The literature review has mapped technical and non-technical factors in two decades. However, the lesson learned from historical data as a basis for decision-making is limited—the mileage factor between the quarry to the basecamp and from basecamp to the project site. This study aims to analyze the factors that influence determining the basecamp location for highwayprojects. The research method used is a case study, with a qualitative approach strategy using a questionnaire from experienced parties in similar projects. Analytical Hierarchy Process approach and in-depth interview with the former technical manager of highway project from a construction company were used as a decision support tool. The results showed that a priority of basecamp selection was determined based on the factor of the distance from the base camp to the project site, the distance from the basecamp to the quarry, the plan for independent material production. Apart from technical constraints, licensing and social issues were a factor in the location determination stage. This study contributes to the decision-making model for selecting basecamp locations at the managerial level in a construction company.

A good coating is one with high performance and durability; has a low surveillance and maintenance requirement; is easily applied with no health risks and finally is cost effective. It is unlikely that a single type of coating would be able to satisfy all these needs. Thus, a decision support tool is needed to help identify the most appropriate choice. This paper presents three simple methods for this selection process, and allows the judgment of more than one expert to be aggregated in order to reach a consensus. An example is presented which demonstrates the application of these methods, by providing the decision-maker the ability to weigh options and set priorities in deciding on the best compromise solution for a corrosion coating material.

Stormwater Control

Integrated decision support tools are needed to investigate the tradeoffs of stormwater control measures (SCMs) and determine the optimal suite of SCMs based on the needs of watersheds. In this study, an urbanized watershed undergoing infill development (the Berkeley neighborhood located in Denver, CO, USA) was modeled using a modified version of the U.S. Environmental Protection Agency’s (EPA) System for Urban Stormwater Treatment and Analysis IntegratioN (SUSTAIN). The primary goal was to compare the relative performance between green and grey SCMs, use optimizations and a planning-level approach to assist in decision-making, and discuss how stakeholder and community preferences can shift which SCMs are optimal for the watershed. Green and grey SCMs have variable hydrologic performance based on design and function, and both offer benefits that may be important to decision makers. Our results showed that infiltration trenches and underground infiltration were optimal for reducing flow volumes while vegetated swales and underground detention were optimal for pollutant concentration reduction. Stakeholders value both of these benefits and so the optimal stormwater solution in the Berkeley neighborhood included a mix of green and grey SCMs. Determining the optimal SCMs while considering tradeoffs in costs and associated benefits was complex and multifaceted. Modeling results such as those presented here are critical for informing stakeholders’ decision-making process.

The recent reprinting of Álvaro de Silva’s 1998 edition of a selection of More’s letters prompts the author to examine the subject of Spanish translations of More, and of de Silva’s general commentary on More’s correspondence and on his relationship to other humanists. The author reflects on aspects of More’s personality as exposed in his letters and uses what he finds as a corrective to several biographical misconceptions. He points out the strengths and weaknesses of de Silva’s work and compares it with that of other translators, particularly Elizabeth Rogers, and notes the particularly Spanish quality of de Silva’s edition.
