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.

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.

And Function

In the recent years, the design for high-rise residential buildings in Shanghai has been changing in floor plan. It is the transformation in the shape of the house from residential tower-shaped buildings into combined apartment buildings; the transformation in constitution of floor plan, the number of apartment in each floor; the transformation in area and function of each apartment and even in living habits. Studies of the transformation in shape mentioned above were carried out by the morphology methodology. Combined apartment buildings in Shanghai combined together leads to high economic benefit, and the number of floors is up to 34 floors. Auxiliary area which is shared equally to each apartment, accounts for an approximately large portion of a typical floor plan. Each apartment in Shanghai must be added 12-18% of external auxiliary area. The cause and effect of the transformation in the design for high-rise apartment buildings are valuable experiences for other developing metropolitans in China, so as other countries in region.

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.

PurposeIn recent years, the number of high-rise buildings in Malaysia has been increasing. Therefore, it is essential to take evacuation into consideration especially for emergency conditions such as fire, explosion and natural disasters. This research aims to evaluate the effectiveness of the escape time in typical Malaysian high-rise residential buildings.Design/methodology/approachThis work comprises simulation on three buildings around the Selangor area in Malaysia. Quantitative methodology is adopted using Pathfinder software to simulate the evacuation process and time of the three typical Malaysian high-rise residential buildings. Four parameters were studied namely, the occupant load density, walking speed of first and last occupants, average of evacuation time per floor for the three buildings and effect of placement of emergency staircase on travel time.FindingsFindings show that 12 m2 which is double the allowable occupants' density in Malaysia increases evacuation time by 67.9% while the placement of the emergency staircase on the left and middle section of a building significantly affects the evacuation time by 21.2%. In conclusion, from the simulation studies, it is recognized that a higher occupant's density affects the evacuation time.Originality/valueThis work could provide information on escape time for future construction of high-rise buildings in Malaysia. Hence, the specification and design of buildings could be reviewed based on the results obtained from this simulation. This information could be beneficial to the building regulators and developers thus enhancing the knowledge of building constructor and possible issues in the design of staircases, corridors and height of buildings.
