Framework in developing model of interfloor leakage in high-rise residential buildings in Malaysia

Interfloor leakage is amongst the highest claims reported to the Strata Management Tribunal. This defect affects strata communities directly and indirectly in cost of repair, occupant safety, health and disputes. Regulation 55 of the Strata Management (Management and Maintenance) Regulation 2015 under Strata Management Act 2013 defines interfloor leakage as any evidence of dampness, moisture or water penetration, and has underlined the work process of interfloor inspection. However, issues are investigating the cause of leakage and repair costs, and determining who is responsible for the repair. Conducting defect assessment by standards is the collection of systematic information to evaluate building performance, investigate defect elements and recommend appropriate repairs. The research concept framework examines the effect or influence of each construct on another construct. Constructs are three, namely, interfloor leakage management, legislation and owner satisfaction. Based on the literature review, the conceptual framework is produced, and each of these constructs is developed with several dimensions to be tested. The sequential exploratory design method is used with a combined approach of qualitative interviews and discussions with experts in the field of property management and building pathology to form a questionnaire for distribution to the management. This research is essential to decide how to reduce disputes, discuss the costs of repair and select a party to execute repairs that create quality strata management that benefits the owners, management and stakeholders

Case study: inter-floor leakage in high-rise residential buildings in Malaysia

Building defects are a common issue in the construction industry. Defects of high-rise buildings, such as cracks and leaks, are often caused by poor workmanship, and insufficient and low-quality building materials. Other contributing factors to building defects are inadequate cooperation during construction, poor design and improper installation. Inter-floor leakage is a widespread matter in new homes, leaks are detected late and repeated leaks occur even after repairs have been carried out. Inter-floor leakage often occurs in new homes. Leaks are detected late and repeated ones occur even after repairs are carried out. This study aims to diagnose buildings with inter-floor leakage problems by using several diagnostic tools and techniques like visual, destructive and nondestructive tests. Experts use testing equipment to determine moisture and appropriate maintenance or repair. A case study is carried out on a residential unit with a leak in the ceiling due to a crack on the rooftop. The findings of the study can provide knowledge about building diagnosis to property owners and property managers, identifying the cause of leaks and enabling early detection of building defects and suggested repairs to prevent similar leaks from occurring. By utilizing diagnostic tools and techniques, owners and property managers can detect problems early, minimizing damage and expenses in the long run. Based on the study, existing cracks can be converted into expansion joints, white paint can be used on the walls to control heat, installed thermal insulation to control solar energy stress and waterproof membrane can be applied to prevent moisture penetration
