AN ANALYSIS OF HIGH-RISE BUILDING CONSTRUCTION TECHNOLOGY: A RESEARCH STUDY FOCUSED ON HONG KONG.

Abstract

Production performance concerns in the construction industry often revolve around time, cost, and resource utilisation. In the context of Hong Kong's high-rise public housing building, this article explores the influence of using alternative construction methods or techniques on production performance. The researcher looked at three distinct building plans that all used the same common "Harmony" design. The material handling plant input and floor slab building processes vary among these systems. There is an examination and analysis of three systems' cycle times, manpower utilisation, and expenses. Scheme 2, with its six-day floor cycle, was shown to be the most cost- and labour-efficient choice. Since Hong Kong places a premium on building speed, Scheme 3, which has a four-day floor cycle period, is recommended. Due to space and resource constraints, several technological solutions were implemented in Hong Kong. On the other hand, several accidents happened due to improper use of the technology. As a result, the Hong Kong government issues several regulations and standards for the building sector. The government establishes several pieces of legislation and regulations to keep the building projects under control. To guarantee the works are finished safely and to a high quality, the researcher prepared specifications, practical notes, guidelines, and drawings. Due to employee misbehaviour and errors, several tests were conducted to guarantee high-quality craftsmanship. To ensure that the soil nail length is according to plan, for instance, the TDR test was instituted. The quality and craftsmanship of concrete were checked using cube tests, core tests, and hammer tests. The tensile test was used to evaluate the steel's quality. Tests for cement quality included a bleeding test and a flow cone test.
