Abstract:

PurposeProject schedules have a vital role in the effective management of time, cost, scope and resources in construction projects, and creating schedules requires schedulers with construction knowledge and experience. The increase in the complexity of building projects and the emergence of building information modeling (BIM) in the architecture, engineering and construction industry have encouraged researchers to explore BIM capabilities for automated schedule generation. The scope and capabilities of the developed systems, however, are limited and the link between design and scheduling is st

Abstract:

Today, the development of infrastructure and construction projects in developing countries is of paramount importance. Water projects, in particular, play a crucial role in advancing agriculture, industry, and the economy. The success of these projects hinges on the effective management of time, cost, and quality. The most critical indicator of a project's success is its completion within the forecasted time and budget leading up to its operation.

Abstract:

Scheduling is essential in managing projects. ‘Schedula Anima’ is a new software designed to provide a comprehensive view of schedules between early and late dates for construction project managers. Capturing the dynamic nature of projects, it offers improved visualization through an animation process that creates incremental frames of bar charts and the corresponding resource graphs. As activity delays are simulated, it is observed that delays earlier in the schedule have more significant effects on project completion. A new prioritization method is introduced to evaluate the ease of reschedu

Abstract:

In today's real-life implementations, projects are executed under uncertainty in a dynamic environment. In addition to resource constraints, the baseline schedule is affected due to the unpredictability of the dynamic environment. Uncertainty-based dynamic events experienced during project execution may change the baseline schedule partially or substantially and require projects' rescheduling. In this study, a mixed-integer linear programming model is proposed for the dynamic resource-constrained project scheduling problem.

Abstract:

Choosing the appropriate method in project scheduling is an important thing to meet the needs in construction. Construction projects that have repetitive or repetitive work require a continuous and well-scheduled supply of labor, because the repetitive project work must be able to continue to progress without being delayed. Of the several project scheduling methods, line of balance (LoB) is more suitable for repetitive projects because line of balance (LoB) is a construction project scheduling method in the form of a line that represents one type of recurring activity package. LoB can be appli

Abstract:

Infrastructure development is an important element in supporting economic growth, including in Indonesia. The Waru - Buduran Frontage Road Bridge development project was designed to overcome traffic congestion in the Sidoarjo area as a buffer zone for Surabaya. However, the project faced various obstacles, including schedule deviations and significant costs. This research aims to analyze the project's cost and schedule performance using the Earned Value Analysis method, focusing on Schedule Variance and Cost Variance to identify the main causes of delays and cost inefficiencies and provide rec

Abstract:

Bias in project performance causes schedule and cost to overrun baseline estimates (your model). Bias is the onesided tendency of actual schedule or cost to overrun the model. A Guide to the Project Management Body of Knowledge (PMBOK® Guide) and supporting literature recommend estimating the variability for all project time and cost estimates, and sizing appropriate schedule or cost buffers (also known as contingency or management reserve) using Monte-Carlo analysis or PERT. This paper describes a number of sources of bias in performance of projects to schedule and cost estimates, and provide

Abstract:

The purpose of Engineering Procurement Construction (EPC) general contracting project schedule management is to ensure that the project meets its deadlines, and it plays a critical role in contract performance. In comparison to the domestic general contracting model, project management and coordination are more complex for the general contractor of international EPC projects. As a result, scientific project schedule process control is critical to effectively ensuring project duration, saving project costs, improving project management level, and project quality, and ensuring that the project a

Abstract:

An emerging economy like Ghana, one of the developing nations in Africa, is fortunate to have started exploration not long ago, which means that it is still developing in the field of upstream oil and gas exploration compared to other industrialized nations that have a lot of experience in the field of project management and oil exploration. About 80% of the management style in the upstream oil and gas sector is project-based; therefore, any delays in project deliveries and completion will have a negative effect on completion time and, at the end of the day, affect the performance of the organ

Abstract:

The CPM and PERT are the most popularly used underlying method of schedule planning of construction project, Problematically, CPM and PERT depend on the experiences of project manager, which is not true in railway construction project. A huge deviation occurs between the actual progress and planned schedule. This leads to unreasonable allocation of resources and cost increment. Referring to the characteristics of schedule planning of railway construction projects, we proposed schedule planning conceptual model of railway construction project based on CAS. The model consists of three parts. The

Abstract:

The development of road infrastructure is closely related to national competitiveness and presents significant socioeconomic impacts. However, road construction involves a large budget and is vulnerable to political, economic, social, and project-specific risks, which often result in cost overruns and schedule delays. Assessing the gap between the final performance and the planned performance, and providing feedback to similar projects in the future is essential for successful project planning and management. The aim of this study is to empirically analyze the cost and schedule growth of road

Although venerable by the tide, the tools and metrics used still include CPI, SPI, and performance in the form of schedules; these hardly reflect true scheduling performance, especially in more complex scenarios of building projects subject to multiple variables. Thus, the advanced metrics of EVM introduced for measuring the Earned Schedule (ES), Schedule Variance (SV), and To-Complete Performance Index (TCPI) allow not only the argument of schedules on more rigorous grounds but also for extensive commentary with an eye both to history and future in respect of schedule performance.
