The Interpretative Structural Modeling For Stakeholder Involvement To Reduce Slum Settlements, Bich Hanes Bich, Ayomi Dita Rarasati

Smart City

The array of problems originating from slum settlements not only results in unwholesome environment, unlawful land utilization, and various internal challenges within the vicinity but also impacts the surrounding regions and the overall urban infrastructure network. In pursuit of Indonesia's 2045 Vision, which emphasizes on "equitable and integrated infrastructure development", the zero slums constitutes a pivotal component of the Ministry of Public Works and Public Housing's overarching vision. Nonetheless, a disparity has been identified in addressing slum settlements in West Kalimantan, hindering the achievement of this objective. This research aims to identify the stakeholders and the priority factors in determining …

Project Stakeholder Analysis In Temadore Bridge Construction Development, Hud Rafsanjani, Ayomi Dita Rarasati

Smart City

The construction of bridge is important due to its ability to link communities through land-road connection, thereby saving time and increasing productivity of those living in these areas. Therefore, this research evaluated the Temadore bridge, built to link Ternate City, Maitara land and Tidore City by road to enhance movement and reduce disparities in assessing both areas. Data were collected using the Interpretative Structural Modeling (ISM) which searched for and identified several variables according to the dependence power and driving power. The result showed that construction of bridge increased the movement of community activities and productivity, thereby leading to growth.

Factors Influencing The Occurrence Of Rework In Terms Of Risk-Based Communication Management In Construction Projects, Virani Mayniana, Rossy Armyn Machfudiyanto

Smart City

Rework in a construction project is an unplanned and unwanted activity that requires an action to repeat part or all the work to meet project standards or requirements and, in its implementation, causes increased work, time, and costs. Based on previous studies that discuss the factors that cause rework, poor communication management or coordination between stakeholders is one of the causes of rework. Therefore, a literature study was conducted to identify project communication management risks that allow rework to occur and resulted in 54 communication management risk factors. Furthermore, the results of the literature study were validated by experts who …

Deep Learning Techniques For Efficient Evaluation Of Asphalt Pavement Condition, Kamel Mahdy, Ahmed Zekry, Mohamed Moussa, Ahmed Mohamed, Hassan Mahdy, Mohamed Elhabiby

Mansoura Engineering Journal

For the last few decades, researchers have been devising a simple and cost-effective method to evaluate pavement distresses to give decision-makers adequate feedbacks about the pavement condition of a certain road. Fortunately, with the evolution and progression of computer vision tools and techniques, good results had been achieved regarding the detection, classification, and quantification of road distress. In this paper, a new efficient process of road distress analysis using deep learning models is introduced. This new process was tested on a collected road dataset to evaluate the efficiency and speed of this low-cost road maintenance system. Promising results were obtained …

Numerical Investigations Of Gfrc Beams Strengthened In Shear With Innovative Techniques, Marwa H. Bondok, Gamal I. Khaleel, Ahmed S. Debaiky, Mohamed H. Makhlouf

Mansoura Engineering Journal

This paper discusses the Finite Element analysis (FE) conducted to predict the behavior of Glass Fiber Reinforced Concrete (GFRC) beams without shear reinforcement (stirrups) and strengthen them with proposed techniques to increase their shear strength. for this study, A total of eighteen (18) (120 * 300 * 2200 mm) specimens were modeled using Ansys™ mechanical. The main variables were the percentage of discrete glass fiber in the concrete (0.0, 0.6, and 1.2%), the type of main reinforcing bars (steel or GFRP), the shear strengthening material (GFRP or steel) links, the strengthening systems (side near-surface mounted (SNSM) bars, externally bonded (EB) …

System Dynamics And Topsis Models For Sustainable Building Materials Selection Considering Life Cycle Assessment, Shimaa Elshoubaky, Emad Elbeltagi, Mohammed Abd Elrahman, Islam Elmasoudi

Mansoura Engineering Journal

Construction industry is the most contributor to the environmental impacts. Achieving sustainability in construction is complicated, but one of the most optimal strategies is selecting sustainable building materials.

The major goal of this study is to present a new idea for choosing sustainable building materials (SBMs) by simulating sustainability parameters' behaviour. This research proposes a System Dynamics (SD) model along with the TOPSIS method based on the dynamic interactions among a number of sustainable criteria to help decision makers in sustainable building materials selection. The sustainable criteria that form system boundary are determined from previous studies and experts′ opinions. The …

ASEAN Journal of Community Engagement

Noise pollution can be categorized as a danger in silence. In school, noise pollution inhibits the focus of learning, impairs learning and cognitive development, for example, students' skills to think and understand both oral and written comprehension may be hampered by noise. Many schools in Malaysia experience excessive noise pollution as their locations are very near busy roads. This will be one factor that hinders the implementation of the education system in producing holistic students in order to prepare for the 4IR era. Knowing the importance of this problem, a group of researchers from UTM GREENPrompt, School of Civil Engineering, …
