There is a number of criteria and associated sub‐criteria influencing the match of managers to construction projects. Criteria and sub‐criteria were identified based on a thorough review of the related literature and interviews of management personnel involved in the project managers selection. Project managers characteristics are considered to be less important for an effective project management. The model is based on multicriteria evaluation of project managers. The evaluation embraces the identified criteria influencing the process of construction project manager selection. This paper considers the application of grey relations methodology to defining the utility of alternatives, and offers a multiple criteria method of Complex Proportional Assessment of alternatives with grey relations (COPRAS‐G) for analysis. In this model, the parameters of the alternatives are determined by the grey relational grade and expressed in terms of intervals. A case study presents the selection of construction project manager. The results obtained show that this method may be used as an effective decision aid in multicriteria selection.

AbstractOne of the key problems in managing the realization of a construction project is the selection of appropriate working crews and coordinating their activities in a way that ensures the highest degree of implementation of defined goals (minimizing the project duration and/or reducing downtime and related costs). Most of the existing methods of work harmonization used in construction industry allow obtaining the desired results only in relation to the organization of the processes realization in repetitive linear projects. In case of realization of non-linear construction objects or construction units, it is usually necessary to choose between the reduction of the project implementation time and maintaining the continuity of crews work on the units. It was found that there is a lack in the literature of developed method enabling harmonization of crews’ work, while minimizing the downtime at work and the duration of the entire project taking into account additional constraints, e.g. the need to not exceed the deadlines for the realization of the project stages.The article presents the concept of a multi-criteria optimization method of harmonizing the execution of non-linear processes of a multi-unit construction project in deterministic conditions. It will enable the reduction of realization time and downtimes in work, taking into account the preferences of the decision maker regarding the relevance of the optimization criteria. A mathematical model for optimizing the selection of crews and order of completion of units in multi-unit construction projects was also developed. In order to present the possibility of usage of the developed concept, an example of the optimal selection of crews and their work schedule was solved and presented. The proposed method may allow for better use of the existing production potential of construction enterprises and ensure synchronization of the crews employed during the work, especially in the case of difficulties in acquiring qualified staff in construction industry.

Management Case Study

In the field of engineering and construction, unqualified construction quality, time delays, cost more than expected phenomena to occur. Because of these characteristics such as its large-scale construction projects, long cycle, the production of single and complex, there is greater risk than the production of general products, the risk increases the difficulty of construction project management, operating costs and the possibility of potential losses, therefore, risk management emerged and become an increasingly important integral part of project management. In this paper, fuzzy analytic hierarchy be used to construction project risk assessment, and to order the sort of each risk in order to prevent significant risks. On an actual project - the new stadium construction in Weifang City risk management case study, the reduction of risk of project failure is expected, but also the project is hoped for other industries to provide some reference for risk management.

Project overheads are allocated on a percentage basis to project costs and common to maintain multiple cost objects, but cannot directly be distributed to construction activities. Construction project overheads have to be identified their cost behaviours properly in order to sustain Cost Management and Controlling Practices (CMCPs) during the construction stage. The literature review method identified forty seven (47)project overheads and categorised into four hierarchies (unit, batch, project, and facility levels). Therefore, the identification of project overheads should enable a sustainable improvement to the CMCPs in construction projects.

Un nuevo sistema de gestión de costes de proyectos de construcción para aumentar la competitividad y la trazabilidad para entornos de proyectos. El objetivo principal de la investigación es utilizar nuevos métodos de cálculo de costes en los proyectos de construcción para reducir y controlar las desviaciones de costes y algunas limitaciones que presentan los modelos tradicionales. La hipótesis de la investigación se basa en la capacidad sinérgica del cálculo de costes basado en actividades centradas en el rendimiento, en combinación con el método de cálculo de costes objetivo para fomentar la competitividad del sistema de control de costes para entornos de proyectos. El método se elaboró para controlar los gastos directos y generales del proyecto durante su ejecución. Se realizó una entrevista con 26 directores financieros en dos o cuatro ocasiones entre junio de 2016 y mayo de 2017 con el fin de validar y modificar el método. Siguiendo una entrevista semiestructurada, el método propuesto contribuyó a aumentar la precisión, la certidumbre y la rastreabilidad de los costes y proporcionó la integridad del sistema contable, técnico y operacional. Además, se analizan las desviaciones y se reducen los costes al considerar las condiciones competitivas y estratégicas. También se limita el coste objetivo de los paquetes de trabajo y se genera una alerta al finalizar cada uno de ellos. Además, de acuerdo con el test de Friedman, existe una capacidad competitiva significativa en comparación con el método convencional de control de costes en los proyectos y también se aplica en un estudio de caso. This research proposed a new method for project cost management based on Competitiveness and traceability in a case study and operational situation. The research hypothesis is based on the synergistic ability of performance focused activity-based costing in combination of the target costing method for encouraging competitiveness cost control system for project environments. The method was developed to control, direct and overhead costs of the project during its progress. Also, it uses the feature of activity-driven and different resource drivers to determine the types of costs with the effect of time driver for each activity. An interview was conducted with financial managers during two to four times with the aim of validating and modifying the method. According to a semi-structured interview, the proposed method contributed to increase the precision, certainty, traceability of costs and provided the integrity of the accounting, technical and operational system. It also analyzes deviations and reduces costs by considering competitive and strategic conditions. It's also limiting the target cost of work packages and causing an alarm on the completion of each. According to Friedman test, there is a meaningful competitive ability compared to the conventional cost control method in the projects and it is also implemented in a case study.

Risk Management is recognized as an important exercise that creates value to a project and improves project performance. Time, cost and quality are the primary measures of a project performance in this industry. The success or failure in any construction project can be monitored through the attainment of these primary measures. Notably, Malaysian construction industry is considered as one of the important industries that positively contribute to the increase of Gross Domestic Product and subsequently the growth of the country’s economic development. Unfortunately, this industry suffers poor performance in which it leads to failure in accomplishing effective time, cost and quality performance. Most construction projects face a schedule delay, cost overrun and are poor in product quality. Thus, the aim of this study is to determine the influence of risk management on construction project performance of Malaysian companies based on these three primary measures. The degree of diffusion of risk management practice in the chosen construction project in Malaysia is also examined. The methodological approach exploited in this study is a case study approach involving analysis of documented data and face-to-face interviews with key players that hold different roles and responsibilities. They include a director, project managers, finance managers, contract managers and quantity surveyor managers. The results demonstrate that adopting effective risk management practices positively impacts project performance thus leading to project success. Nevertheless, the lack of knowledge and poor communication of risk management practices in construction projects contribute to the weak implementation of an effective and systematic risk management practices in Malaysia.
