Abstract

In the lower reaches of the Amu Darya River, the hydraulic regime has been significantly transformed under regulated flow conditions. The determination of the Chezy coefficient plays a crucial role in analyzing the kinematics and hydraulic resistance of the river flow. Based on field data obtained from Tuyamuyin, Kipchak, Niyetbaytas, Samanbay, and Kiziljar hydroposts, empirical relationships between the Chezy coefficient, discharge, and morphological parameters were developed. The analysis revealed that conventional formulas proposed by Manning, Forchheimer, Pavlovskiy, Agroskin, and Jeleznyakov showed considerable deviations under regulated conditions due to nonuniform depth distribution and increased roughness coefficients. The derived relationship for the lower Amu Darya provides improved accuracy in estimating the Chezy coefficient compared to classical methods. This approach enhances hydraulic computations and offers a practical basis for riverbed regulation and hydraulic design in managed flow conditions.

Abstract

Project delays frequently occur in construction projects and often result from the inability to accurately identify critical activities within the project network, leading to ineffective time control. Therefore, it is necessary to apply scheduling methods that are appropriate to the characteristics of the project in order to improve time control effectiveness and minimize the risk of delays. The aim of this research is to analyze scheduling results using the Critical Path Method, Program Evaluation and Review Technique, and Line Of Balance method. Also, to determine the difference in project completion duration using the PERT, CPM and LoB Methods. This research employs a quantitative method with a comparative approach, using secondary data that was obtained from a supervisory consultant. The data includes the durations and the work list. The analysis data is obtained to determine the critical path using PERT, CPM and LoB methods. The PERT method calculates three estimation times: optimistic duration, most likely duration, and pessimistic duration to determine the critical path. The results show the CPM and LoB method predicts the completion project in 159 days, and the PERT method predicts the completion project in 164 days. The difference in completing the project using the CMP and PERT methods is 5 days. The difference in project completion duration between LOB and PERT is 5 days. In contrast, no difference is observed between the CPM and LOB methods, as both yield an identical project completion time of 159 days.

Abstract

The objective of this study is to develop porous cement concrete for road pavements using construction waste aggregates to achieve the required surface characteristics. The research method in this study was laboratory experiments involving a series of concrete mixtures with varying waste content between 10% and 30%. Meanwhile, the cement content and water/cement ratio remained constant, based on previous studies in which the effects of these variables had been evaluated. The results of this study show that the performance of porous cement concrete has undergone two types of permeability evaluation tests, laser measurements for flatness and texture analysis, and the British Pendulum Test for friction evaluation. The aggregate gradation follows the PA12.5 specification, with a maximum aggregate size of 14 mm, serving as a reference concrete without recycled aggregates. Mechanical strength tests were included in the performance evaluation to measure the durability of the concrete. The findings of this study indicate that porous cement concrete containing demolition waste is a viable and sustainable solution for managing demolition waste materials.

Abstract

Urban public spaces are important components of sustainable urban infrastructure because they support social interaction, community activities, and public well-being. However, many urban public spaces experience declining quality and underutilization due to inadequate spatial settings and limited supporting facilities. This study examines the relationship between spatial settings and patterns of public space utilization in Maccini Sombala Park, Makassar. The study applies a qualitative descriptive approach using behavioral mapping, semi structured interviews, and field documentation. The behavioral mapping method used is Place-Centered Mapping to identify activity concentration, spatial utilization patterns, and the influence of spatial attributes on user activities. The findings reveal that user activities are concentrated in spaces with better accessibility, safety, spatial dimensions, and supporting facilities such as seating facilities, vegetation, and jogging paths. Meanwhile, areas lacking these attributes tend to become underutilized and socially inactive spaces. The results indicate that spatial settings are closely associated with social interaction, inclusivity, comfort, and public participation within urban public spaces. Social sustainability in parks can be achieved through users’ engagement with the park through active use of the space and the diversity of activities.  This study highlights the importance of user-centered spatial planning in supporting socially sustainable public infrastructure and improving the effectiveness of urban public spaces.

Abstract

One of the key aspects of construction is the use of concrete, making research to improve its quality highly necessary. This study uses recycled aggregate in the form of granite waste as a partial substitute for coarse aggregate to produce environmentally friendly concrete while maintaining its quality. The aim of this research is to determine the effect of varying granite waste content on the compressive strength and modulus of elasticity of concrete. The experimental method is used in this research, which focuses on concrete with granite waste variations of 0%, 15%, 30%, and 45%. Testing the compressive strength and modulus of elasticity of concrete using cylindrical specimens with a diameter of 15 cm and a height of 30 cm with a Compression Testing Machine and an additional dial gauge to measure specimen deformation. The compressive strength tests for concrete with granite waste variations of 0%; 15%; 30%; and 45% result in values of 22,27 MPa; 23,26 MPa; 29,27 MPa; and 25,28 MPa, respectively. Meanwhile, the modulus of elasticity tests yield values of 21727,29 MPa; 21882,92 MPa; 25920,23 MPa; 22585,91 MPa, respectively.

Abstract

The purpose of this study is to clarify the degree to which inadequate planning causes building project implementation difficulties in Iraq between 2020 and 2025. It will attempt to understand the causes contributing to inadequate planning, which subsequently impact project duration and result in delays. The research population comprised specialized project management organizations and medium to large contracting organizations across all construction sectors in Iraq, including building, road construction, water and sanitation, electricity works, and infrastructure development. The research population comprised 42 project managers from project management organizations and 40 project managers from contracting organizations, both drawn from the intended market of 50 individuals in each category. The research variables were categorized into three principal variables, ten sub-variables, and forty-two measurement items. The present research's results were obtained by conducting a statistical analysis of the data. The contracting companies' inadequate comprehension of management and engineering planning concepts, insufficient recognition of time's significance, the necessity of effectively leveraging the technical and managerial benefits of planning, adherence to engineering planning principles in construction projects, a lack of understanding of the elements contributing to a plan's success, and an insufficient grasp of planning's efficacy and its impact on project success are the primary reasons for obstacles in satisfaction of engineering projects.

Abstract

The development of a teaching hospital is an important strategy to improve the quality of medical education while expanding public access to healthcare services. This study aims to evaluate the feasibility of the proposed Universitas Negeri Surabaya (UNESA) Teaching Hospital from technical and financial perspectives. A descriptive quantitative approach was employed using a project feasibility study with a 15-year investment projection. The technical analysis assessed the conformity of hospital facilities and spatial planning with applicable standards, while the financial analysis applied Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PP) as investment evaluation indicators. The results indicate that the proposed hospital design satisfies the requirements for healthcare services and clinical education. The estimated total investment is IDR 1,063,446,660,386, with first-year operational costs of IDR 15,954,461,306 and projected revenue of IDR 81,786,688,000. Financial evaluation produced an NPV of IDR 91,884,177,286, an IRR of 12.3%, and a Payback Period of 7.39 years. These findings demonstrate that the proposed UNESA Teaching Hospital is technically feasible and financially viable, making it a promising investment to support sustainable healthcare service delivery. In addition to financial and technical performance, the design also incorporates lifecycle building management and green hospital principles, including energy- and water-efficient utility planning and zoning for infection control, reinforcing the sustainability dimension emphasized by the journal's scope.
