A survey on classification of maintenance fund for high rise residential building in Klang Valley

High-rise residential building is a type of housing that has multi-dwelling units built on the same land. This type of housing has become popular each year in urban area due to the increasing cost of land. Unfortunately, there are several issues occurred in managing high rise residential building especially in maintenance fund. Thus, distribution of maintenance fund need to be clarified in order to make it well organised. The purpose of this paper is to identify the classification of maintenance fund distribution at high rise residential building. The survey was done on 170 high-rise residential schemes by using stratified random sampling technique. The scope of this research is within Klang Valley area. This area is rapidly developed with high-rise residential building. The result, there are five classification of maintenance fund identified in managing high-rise residential building scheme namely, management fund for administration and utilities, maintenance fund for exclusive facilities, maintenance fu...

Classification of basic facilities for high-rise residential: A survey from 100 housing scheme in Kajang area

High demand for housing and limited land in town area has increasing the provision of high-rise residential scheme. This type of housing has different owners but share the same land lot and common facilities. Thus, maintenance works of the buildings and common facilities must be well organized. The purpose of this paper is to identify and classify basic facilities for high-rise residential building hoping to improve the management of the scheme. The method adopted is a survey on 100 high-rise residential schemes that ranged from affordable housing to high cost housing by using a snowball sampling. The scope of this research is within Kajang area, which is rapidly developed with high-rise housing. The objective of the survey is to list out all facilities in every sample of the schemes. The result confirmed that pre-determined 11 classifications hold true and can provide the realistic classification for high-rise residential scheme. This paper proposed for redefinition of facilities provided to create a bet...

Maintenance Performance Quadrant for Rainwater Harvesting System

Maintenance performance is a key aspect in sustaining the RWH system. This is to ensure the maximum value of installing the RWH system as well as ensuring the system performs throughout the buildings lifetime. Two instruments were used during this research namely physical condition survey and questionnaire survey. The results from both instruments demonstrated cross-combination finding via maintenance performance quadrant at the end of analysis. Based on the study at 16 government buildings throughout Malaysia, the results show the majority of buildings need improvement in terms of their maintenance management, while two buildings have bad practice, which needs total refurbishment for the RWH system as well as their maintenance management. In conclusion, the physical condition of the RWH system for government building in Malaysia is regarded good and safe implemented. However, the maintenance performance can be improved with a proper maintenance guideline and management policy by the organization involved.

Residual Compressive Strength of Lightweight Foamed Concrete after Exposure to High Temperatures

Even though lightweight foamed concrete has low mechanical properties compared to normal weight concrete, there is a potential of using this material as partition or load-bearing wall in low-rise residential construction. Before it can be considered for use as a load-bearing element in the building industry, it is necessary to acquire reliable information of its mechanical properties at ambient and high temperatures for quantification of its fire resistance performance. This paper will present the results of experiments that have been carried out to examine and characterize the residual compressive strength of foamed concrete after high temperatures. Foamed concrete with 700 kg/m3 and 1000 kg/m3 density were cast and tested. The compression tests were carried out at ambient temperature, 100, 200, 300, 400, 500 and 600°C.
