High Rise

Residential high-rises are unique properties that differ from landed properties such as bungalows or terrace houses. They are unique insofar as, after the properties have been occupied, facilities must be jointly managed by residents. The continuous growth of high-rise residential buildings specifies that there is a need for effective ownership and property management system to instill a valuable living experience among high-rise residents in this country. Looking at this scenario, this research takes an initiative to develop a mobile application that supports streamline information with assistive features to improve communication and information sharing for high-rise residential management in Malaysia. This aim is achieved by answering three research objectives, including identifying user requirements, designing the application prototype and developing the artefact and evaluating the artefact. The study was conducted together with LT Sdn Bhd, the property management company responsible in managing and maintaining property related matters of Seroja Apartment. An adopted conceptual framework for property management based on the sustainable indicator dimensions for property management and applicable features from existing mobile application to develop the artefact has been proposed. The conceptual framework was proposed based on literature review and nature of work observed on site. Lastly, the study successfully validated the proposed adopted framework against the artefact, the MyLT mobile application.

The study seeks to examine the approaches taken currently with regard to scholarship on ecclesiology from the patristic era, the medieval era to that of the reformation and beyond. The study evaluates the various ecclesiological approaches of various confessional traditions that have defined ecclesiology over time. In progression, the study examines contextual ecclesiologies with a focus on three specific cultural geographical environments of Africa, Asia, and Latin America. This is because of the significance that these regions play in the current global shift within Christendom. African ecclesiology has been the centre of focus in an attempt to link all the discussed ecclesiologies with the African Christian thought. The study intends to review the Ubuntu concept and to capture the concept of the humanness of people in the African setting. The study intends to expose the gap in the literature demonstrating that the African conceptual framework can indeed be of use in articulating theology relevant to the African world. The study was keen to evaluate the contribution towards the development and construction of an African ecclesiology using the Ubuntu concept as a remedy to solve ecclesiological problems witnessed in Africa.

The main goal of this study is to explore the adoption of a design for manufacturing and assembly (DfMA) and building information management (BIM) approach during the whole lifecycle of assets. This approach aims to tackle issues inherent in the design of traditional construction methods, such as low productivity and quality, poor predictability and building performance, and energy use, through the implementation of a BIM library of off-site components. In recent years, a renewed interest has been directed to the attempt to provide solutions to these urgent problems through the adoption of new advancements in technologies. However, while there are studies focussing on a BIM-DfMA approach, there is a lack of research regarding how this approach should be adopted during the whole lifecycle of the assets. Furthermore, to the best of our knowledge, defining an efficient way of developing a component-based BIM object library has not yet been included in any of the available studies. A mixed methodology approach has been used in this research. A conceptual framework was developed as the result of an extensive literature review to investigate new advancements in the AEC sector. Following the literature review, the framework was tested and validated through a case study based on the production and adoption of a BIM library of off-site components at the design stage of an asset. The architecture, engineering, and construction (AEC) industry has recognised the necessity of a new approach that helps to resolve the well-known issues presented in traditional methods of construction. The conceptual framework and case study proposed presents a valuable new method of construction that support the implementation of a BIM and DfMA approach, highlighting their benefits. This framework has been created using many valuable and reliable sources of information. The result of this research supports the idea of a novel new construction method that focuses on a manufacturing-digital-driven industry, with the use of DfMA in a BIM-integrated approach. This novel method will add significance and be beneficial for a wide range of aspects in the construction sector, contributing to the theoretical and practical domain.

Since 1980’s, the rapid economic growth resulted in so many aged apartment buildings in South Korea. Nevertheless, there is insufficient maintenance practice of buildings. In this study, to facilitate the building maintenance the authors classified the building defects into three levels according to their level of performance and developed a mobile application tool based on each level’s appropriate feedback. The feedback structure consisted of ‘Maintenance manual phase’, ‘Online feedback phase’, ‘Repair work phase of the specialty contractors’. In order to implement each phase the authors devised the necessary database for each phase and created a prototype system that can develop on its own. The authors expect that the building users can easily maintain their buildings by using this application.

In recent years, contractors have frequently needed to apply innovative technologies to fulfil architects’ creative and intricate designs. They have often encountered abnormal construction conditions. One of the challenging and difficult process is the lifting of a heavy structure called the sky transfer truss (STT), especially if undertaking such a lift is not prevalently experienced. This can result in hazards, accidents, schedule delays, and financial losses to contractors. Traditionally, this structure is fabricated at elevation using scaffolds; however, this approach is costly, time-consuming, and labour-intensive. We introduce a procedure for lifting a 600 metric ton structure that has been fabricated on the ground with a synchronous hydraulic jack-up system. We also discuss the technical difficulties of integrating such a structure into a housing facility. This note addresses several challenging issues: high-accuracy fabrication, design of preventing interference and deformation, and the development of a construction procedure. The case study may be helpful for the flexible construction of extended designs and for the use of a jack-up system in lifting heavy structures of massive sizes and weights.

We have witnessed vast economic, social, technological, and environmental changes that have influenced patterns of urbanization. Through all these years urban planning has also experienced major reforms. During last two decades, with emergence of knowledge economy, it is claimed that the nature of urban development has changed; this new notion of development is called knowledge-based urban development. As there is not clear methodology for directing cities development process, this chapter aims to formulate a conceptual model for cities leadership towards knowledge-based urban development. This chapter considers the city of Isfahan, Iran as a case study. Finally, a model is proposed according to literature review and using ANP method for analyzing the data gathered from the context. This conceptual model has also prioritized effective factors for KBUD.

ABSTRACT This study examines the daylight and energy performance of 27 external shading scenarios in a high-rise residential building in the urban tropics. The cooling energy, daytime lighting energy and the spatial daylight autonomy (sDA) of the building model were simulated in Rhino3D and Grasshopper simulation software. The best performance scenario (vertical and horizontal shading on the twentieth floor, horizontal shading only for the eleventh floor and no shading for the second floor) satisfied 75 sDA(300lx|50) with corresponding annual enery performance of 16%–20% in the cardinal directions. The baseline scenario, which is the current practice of providing balconies on all floors, reduced daylight to less than 75 sDA on the eleventh and second floor, even though it had higher annual enery performance (19%–24%) than the best performance scenario. Application of the design principles to a case study indicated that 58% of the spaces had over 75 sDA for both Baseline and Best performance scenarios, while an increase in enery performance of 1%–3% was found in the Best performance scenario compared to the Baseline.

In Indonesia RC structures are widely used for high rise, low rise, shop offices, as well as residential buildings. In February 2018, the first author introduced an RC beam design application for Android [12] for two options. Option one is for calculating nominal moment (Mn) and nominal shear force (Vn) of the section when the beam dimensions (b, h) and reinforcements are known; option two is to calculate the number of reinforcements for Mn and Vn when the dimensions (b, h) are known. In this paper, the first author added option three, namely the optimization for the design of RC beams when the internal forces are known and the application calculates the most optimal dimensions (b, h) and reinforcements. The application developed is named Civil Engineering Mobile Application for Concrete Beams (CEMA) and is called C2. In CEMA the user can follow the step by step calculation and the results of the calculation are stored in a database. For option three of CEMA (optimization of RC beam sections), the application was validated by another method called Teaching-Learning-based Optimization (TLBO) method [10]. It is believed that CEMA which is based on SNI 2847:2013 can be useful for Indonesian structural engineers designing and supervising actual construction RC buildings.
