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

Abstract

Time, money, and resource utilisation are common points of contention when discussing production performance in the construction sector. This article examines the impact of adopting different construction methods or techniques on production performance within the setting of a high-rise public housing block in Hong Kong. The investigator compared three separate floor layouts that had the same "Harmony" layout. Each system has its own unique procedure for constructing floor slabs and material processing plant inputs. The cycle times, labour utilisation, and expenditures of three systems are examined and analysed. The most labour- and money-efficient option was Scheme 2, which has a six-day floor cycle. Scheme 3, with its four-day floor cycle length, is suggested since speed is highly valued in Hong Kong. Space and budget limitations necessitated the implementation of many technology solutions in Hong Kong. Meanwhile, a number of mishaps occurred as a result of people misusing the technology. So, the government of Hong Kong establishes a number of rules and guidelines for the construction industry. In order to maintain control over construction projects, the government enacts several laws and regulations. The researcher meticulously planned the project by creating detailed drawings, specifications, practical notes, and directions to ensure a safe and high-quality completion. Multiple tests were carried out to ensure top-notch workmanship in response to staff misconduct and mistakes. For example, the TDR test was implemented to guarantee that the soil nail length is in accordance with the plan. Cube, core, and hammer tests were used to evaluate the concrete's quality and workmanship. The quality of the steel was determined by doing the tensile test. A bleeding test and a flow cone test were used to evaluate the quality of the cement.
