Abstract

In Hong Kong, owing to the limit space and resources, many technologies were introduced to solve the problem. However, a lot of accident occurred because the technologies were used incorrectly. Hence, Government produces a lot of code of practice (COP) and guidelines to control the construction industry in Hong Kong.

Owing to misconduct and mistake produced by workers, many tests were used to ensure good quality and workmanship. For example, TDR test was introduced to ensure the length of soil nail fulfil the design. Cube test, core test and hammer test were introduced to check the concrete quality and workmanship. Tensile test was adopted to check the quality of steel. Bleeding test and flow cone test was used to check the quality of cement. A general procedure of construction works and main point of COP will be introduced in this report. Common irregularities were mention to awake reader attention.
