This paper describes the importance of applying proper management in dealing with delays in construction for a growing economy. The main objective of this paper is to identify the management tools that are practiced in the local construction industry in mitigating delay. It also aims to identify the main factors that lead to project delays and to suggest recommendations on how to overcome or mitigate effects of the problem. Data is gathered from responses from questionnaire survey and interviews with those involved in construction project. The surveys and research findings indicate that delay incidents occur mainly during the construction phase of a project and one or more parties usually contribute to delay. This paper highlights the importance of having more experienced and capable construction managers as well as skilled laborers to enable the industry to develop at a faster rate either nationally or internationally.

The advancement in sustainable construction has stimulated wide-ranging investigation of construction materials and practices globally. With exceptional thermal properties, fire resistance performance, excellent strength, and outstanding durability, concrete is the utmost extensively utilized construction material around the world. Taking into consideration the quantity of concrete necessary for numerous constructions works, improving concrete sustainability would be an extremely attractive potential. Lightweight foamed concrete (LFC) is tremendously permeable, and its mechanical properties weaken with a growth in the volume of voids. Air-void segregation from solid cement phases by means of aging, drainage, and merging of voids can trigger and reduce the stability and consistency of the emitted pores, making the LFC less reliable for main utilization in load-bearing components and structural elements. In turn, to augment LFC mechanical properties, the LFC cementitious matrix can be adjusted by adding various nanoparticles. The influence of magnetite nanoparticles (MNP) in LFC was not examined in the past; hence, there is some vagueness considering the mechanism to which level the MNP can affect the LFC mechanical properties. Thus, the aim of this study is to investigate the influences of MNP on the compressive, splitting tensile, and flexural LFC of 1000 kg/m³ density. Six MNP weight fractions of 0.10%, 0.15%, 0.20%, 0.25%, 0.30%, and 0.35% were considered. The parameters accessed were compressive, splitting tensile and flexural strengths. The correlation between strength parameters was established as well. The results indicated that a 0.25% weight fraction of MNP gave the best performance in terms of compressive, flexural, and splitting tensile strengths. The presence of MNP in the LFC matrix enhances the viscosity and yield stress of the mixture as well as an augmented utilization of LFC cementitious binder content, which can sustain the integrity of the wet networks hence preventing further amalgamation and aging of the voids.

Over the past decade, there has been significant growth in the literature addressing risk issues associated with Public–Private Partnerships (PPPs). However, few studies have attempted to comprehensively map and visualize research in this domain. This study aims to fill this gap through a systematic literature review conducted in four stages, utilizing knowledge mapping analysis. More than 400 peer-reviewed articles published between 1990 and September 2023 were examined, making this study the first to analyze such a substantial sample of papers in this field. The research identifies three distinct phases of growth trends in PPP risk management studies. To minimize arbitrariness and subjectivity in analyzing research focuses, this study employed a scientometric approach using VOSviewer software (version 1.6.19), which provides insights into the current state and trends of research on PPP risk management, including high-frequency keywords, contributions of core authors, and distribution across countries, regions, institutions, and journals. In addition to the scientometric analysis, a qualitative review identified six primary research interests, various research perspectives, and diverse methodologies present within the literature. Based on these findings, this study culminates in the development of a conceptual model for risk management in PPPs, offering a structured framework for future research and practical application. This study contributes to the literature by providing the first large-scale, comprehensive mapping and analysis of PPP risk management research, presenting a novel conceptual model that connects theoretical insights with practical implications, and highlighting key areas for future exploration.

Design Management is a systematic method of managing design process through integration of multiple stakeholders in a construction project. Its role and activity are about bringing ideas together, connecting, integrating, communicating, innovating and collaborating design activities, people, processes and resources that are related to the project. Project success can be measured either by objectives or subjective measures where both have their own contribution towards project management success and product outcome success. For this study, project success takes into consideration both measures. This is due to design-caused defect was found as the highest contribution in project defect when measured by cost. The aim of this research is to determine the relationship between design management and project success. For this research, the components of this theoretical framework were developed based on the theories and empirical evidence relating to design management and project success measure. The outcome shows that 41processes had been classified into 7 project stages: project initiation, preparation of design outline, conceptual design, detail design development, procurement, construction and project operation and 6 components of success measure had been identified: Objective measure consists of time and cost and subjective measures look into quality, health and safety, functionality and end-user’s, client’s, design teams and construction team satisfaction.

This study experimentally examines the relationship between integrated information sharing, interior designer capability, and AI-enhanced software, particularly CAD software. 409 of 500 construction interior designers participated in the survey. Pearson correlation explored direct and moderating effects. EE(External Environment), TL (Technical Level), CE (Communication Effect) and AI (Artificial Intelligence) as a moderator were positively connected to OS (Content of Integrated Sharing) and QIS (Quality of Integrating Sharing). This study examines interior designers' content and quality integrated sharing using AI-enhanced software. The findings support construction decision-making and strategic planning. This study illuminates the importance of seamless information exchange and its relationship with AI solutions, helping construction companies improve processes and collaboration. This study suggests ways to improve efficiency and innovation in many construction processes, beyond interior design.
