Influence of Technical Reasons on Cost Overruns of Infrastructural Projects: A Sustainable Development Perspective
Authors: Marijo Lovrinčević; M. Vukomanović; Romano Perić
Year: 2024

Cost overruns are a significant issue in infrastructure projects, adversely affecting not only economic performance but also sustainability goals by straining resources and extending project timelines. There is consensus among researchers about the persistence of cost overruns and the importance of accurate estimates. However, there are significant differences in the explanation of the reasons for the overruns. While we recognize the importance of understanding the reasons for cost overruns at all stages of project development, we have focused on the reasons for cost overruns after contract award due to the rarely available real and valid data collected at the source of the information. We analyze the deviations between actual and contracted costs, as well as the dependence of cost deviations of individual project types on the size of the contract. For example, the size of the tunnel significantly affects relative cost deviations, while for standard viaducts or road sections this effect is minimal. The results confirmed that cost overruns are less frequent in standard facilities than in those where the experience factor has little influence on the final cost estimate. For example, deviations in the average value of the contracted costs for highway sections range between −12.1% and 27.9% of the contracted value, and for standardized viaduct projects they range between −16.73% and 6.27% of the contracted value. The type of distribution function of deviations between actual and contractually agreed costs was investigated, and a predictive model for estimating future cost deviations of project programs was presented. The goal is to improve economic sustainability and the related optimization of resources in the development of infrastructure, which contributes to the broader agenda of sustainable development. The results encourage the adoption of improved project documentation and forecasting tools, which are essential for sustainable project management.

CONSTRAINTS IN SCOPE MANAGEMENT FOR TURNAROUND/SHUTDOWN PROJECTS
Authors: Duraisamy Dhanaraj; Saravanan Subramanian
Year: 2023

Turnarounds are unique maintenance projects with a high probability of having many constraints in scope of works which
results in time delay, and cost overrun. Constraints are a regular and inevitable occurrence in project management and
expected to deliver the results while dealing with them regularly. Management of uncertainty is an essential condition for effective project
management. PMBOK® describes Project Scope as the “The work that needs to be accomplished to deliver a product, service, or result with the
specied features and functions.” A well-dened and controlled scope will be the primary key to delivering a safe and successful turnaround, in
agreed cost and within specied schedules to the organization. The purpose of the project management is to foresee or predict dangers and
problems as possible; and to conclude, organize, control, report these so that the project is completed as successfully as possible despite all the
risks. Negative effects stemming from such uncertainties can be eliminated by following best practices for turnaround projects. This explores
principal constraints of scope management and industry best practices to overcome.

Year: 2024

The rapid progression of technology in today's globalized era has created a heightened demand for efficiency and effectiveness in various aspects of life. This demand is particularly evident in the management of student activities, such as the OSIS clean-up events held on Saturdays. These events, while important for fostering a sense of community and responsibility among students, often face challenges due to manual and non-systematic data management processes. We developed a project management information system to manage attendance and data related to Clean Saturday activities, addressing these challenges. This system utilizes the waterfall method, a structured approach that allows for quickly identifying and resolving issues that may arise during the management process. By implementing this system, Clean Saturday activity management becomes more streamlined and efficient, resulting in improved overall effectiveness. The outcomes of this research are twofold. Firstly, it simplifies the data processing involved in managing attendance at Clean Saturday events, making it easier for OSIS personnel to track and analyze participation. Secondly, it enhances the overall efficiency of the OSIS clean-up program, allowing for better resource allocation and improved outcomes for both students and the community at large.

Importance Factor Analysis of Quality Assurance for Contractor Competitiveness
Authors: Mega Dewi Ashari Putri; Y. P. Devia; M. R. Anwar
Year: 2024

Population growth led to massive construction development, with increasing demand every year. One of those demands is housing construction. The high demand for this house has led to the emergence of new contractors on a local scale, with products and services of unstable quality. Hence, the contractors need to be more competitive in the industry. This research aims to identify and analyze the important factors influencing quality assurance (QA) and the competitiveness of local contractors in housing construction projects. The analysis is grounded in three primary frameworks: ISO 9001:2015 (Quality Management Systems), PMBOK 6th Edition (Project Management Body of Knowledge), and Ministry of Public Works and Public Housing Regulation No. 4 of 2009. The research design used statistical analysis, Relative Importance Index (RII), and Analytical Hierarchy Process (AHP) to identify key factors. Research findings indicate that leadership commitment, project resources, and quality documentation are the three most critical factors. Regardless of the identified critical factors, all factors contribute to a significant influence on successful performance. The proposed strategic approach involves sequentially improving the "quality of work output," followed by "customer retention" and "project cycle efficiency." These findings can serve as a guideline for contractors in making decisions to enhance their competitiveness.

This study was carried out to rank and prioritize the aspects that have been shown to have an impact on the improvement of construction project management (CPM) performance based on value engineering. This analysis was carried out with the Iranian construction industry’s current situation in mind. The respondents and the Delphi panel were chosen from among Iranian managers and project management professionals with a focus on building projects. These professionals had more than 20 years of experience working on international projects, and in addition to their expertise in project management, they also understood the principles of earned value analysis and value engineering. Thus, the components extracted from the literature review were used as the basis for designing a structured interview based on 39 important effective components previously determined as identified factors. The questionnaires were distributed among the experts, and the returned questionnaires were analysed using the SWARA technique to rank the weight and importance of the factors. Using the SWARA method, the opinions of the expert panel members consisting of 20 engineers and a semi-structured questionnaire was used to gather expertise in project management and managers, with a focus on Iranian CPM. As shown by the results, stakeholder management, time value of money, and worth, allocated the first to the third rank to themselves with respective weights of 0.104, 0.103, and 0.087. The sub-criteria of cost objective, function objective, and value objective were in the 37th to 39th ranks with respective weights of 0.00050, 0.00033, and 0.00021.

The requisite variety of skills for IT professionals
Authors: K. Gallagher; K. Kaiser; J. C. Simon; C. Beath; T. Goles
Year: 2010

Introduction IT professionals are beset by ongoing changes in technology and business practices. Some commentators have suggested that, in order to stay competitive, IT professionals should retool themselves to gain competency in specific in-demand technical skills. This article argues that thriving in such a dynamic environment requires competency in a broad range of skills, including not only technical skills, but non-technical skills as well. Our research shows that IT departments in non-IT companies report that while both technical and non-technical skills are important, the skills most critical to retain in-house and most sought in new mid-level employees are non-technical skills such as project management, business domain knowledge and relationship skills. These skills are critical because they enable IT departments to work effectively with other departments, internal users, and external customers and suppliers. Non-technical skills leverage technical skills to augment the organization's overall effectiveness in designing and delivering solutions to meet an organization's challenges and opportunities. These findings depart from previous articles emphasizing technical skills as a basis for valuing IT workers and other research recommending business-oriented skills only for those managing IT workers, not for IT professionals themselves. Our findings lead us to the realization that in today's environment of continuous and fast-paced change, a mix of skills is essential for IT professionals. We believe that the Law of Requisite Variety can help explain the need for greater breadth of knowledge and skills among IT professionals. From cybernetics, the Law of Requisite Variety states that adapting to change requires a varied enough solution set to match the complexity of an environment. In this case, IT workers need a broad enough range of knowledge and skills to meet the demands of their increasingly dynamic and complex profession. Based on our research, we offer a framework outlining six skill categories. We believe that all six skill categories are critically important for the career development of IT professionals.
Research on Fine Cost Control of Civil Engineering Works Supported by Building Information Modeling
Authors: Xiaoping Zhan
Year: 2024


 The problems of cost control in the development process of the construction industry are endless, and cost control, as a core task in the process of project management, has a decisive role in the realization of project economic benefits. This paper combines the DEMATEL method and WBS work breakdown structure to screen and decompose the factors affecting cost under the cost control theory. Then, BIM5D technology is introduced to construct a refined cost control model based on the combination of the earned value method and BIM technology, in which the BIM-5D model can become its grassroots database and combined with the earned value method to provide the basic data for cost monitoring, cost early warning, cost correction and cost prediction, to realize an effective and refined control of costs. The case study shows that enterprise infrastructure, human resource management, internal logistics, procurement and bidding, cooperative and competitive relationships, technology development, project construction, completion and acceptance, and subsequent maintenance services all affect civil engineering costs. The control method can effectively control the construction progress and cost status, can play a good effect on the schedule-cost synergistic control, and provide support for the project management decisions of the constructor in the construction stage.
A Statistical Method for Estimating Activity Uncertainty Parameters to Improve Project Forecasting
Authors: M. Vanhoucke; Jordy Batselier
Year: 2019

Just like any physical system, projects have entropy that must be managed by spending energy. The entropy is the project’s tendency to move to a state of disorder (schedule delays, cost overruns), and the energy process is an inherent part of any project management methodology. In order to manage the inherent uncertainty of these projects, accurate estimates (for durations, costs, resources, …) are crucial to make informed decisions. Without these estimates, managers have to fall back to their own intuition and experience, which are undoubtedly crucial for making decisions, but are are often subject to biases and hard to quantify. This paper builds further on two published calibration methods that aim to extract data from real projects and calibrate them to better estimate the parameters for the probability distributions of activity durations. Both methods rely on the lognormal distribution model to estimate uncertainty in activity durations and perform a sequence of statistical hypothesis tests that take the possible presence of two human biases into account. Based on these two existing methods, a new so-called statistical partitioning heuristic is presented that integrates the best elements of the two methods to further improve the accuracy of estimating the distribution of activity duration uncertainty. A computational experiment has been carried out on an empirical database of 83 empirical projects. The experiment shows that the new statistical partitioning method performs at least as good as, and often better than, the two existing calibration methods. The improvement will allow a better quantification of the activity duration uncertainty, which will eventually lead to a better prediction of the project schedule and more realistic expectations about the project outcomes. Consequently, the project manager will be able to better cope with the inherent uncertainty (entropy) of projects with a minimum managerial effort (energy).
Studying Collaborative Approaches to Improving the Quality of Management Information in IT Projects
Authors: Marcello Presulli
Year: 2016

The management of IT projects often suffers from the absence of a continuous flow of comprehensible information and a uniform representation of the desired data. This is why the quality of the presented information is often questionable. Project decisions taken at those information bases are often suboptimal and leave a feeling of insecurity. This paper proposes an approach to mitigate those problems by means of a collaborative acquisition of necessary key factors. The collaboration was carried out in 6 iterative meetings with 4 selected industrial partners. Based on the results of these meetings and Design by Research as chosen methodology, a specification was derived which guided the creation of a research software prototype for the subsequent testing phase. The prototype supported improved project-information representation with meta-tagging through keywords. Qualitative and quantitative data were obtained during testing of real projects of the industrial partners and were analyzed afterwards by a suitable mixed method approach. With 6 out of 8 positive tested hypotheses, the results show a significant improvement in the key issues, such as a continuous availability of key facts, improved reliability of the data, and less dependence on individuals during reporting. These initial results point to the fact that the path taken in this study is a promising one towards improving the flow and presentation of information in project management generally. Nevertheless, an advanced follow-up study is recommended for deriving yet more solid ground for the derivation of highly usable software support tools.
