Abstract: The construction of bored reinforced concrete cast-in-place pile might be affected by soil strata changes and surrounding environment. Critical aspects in the bored concrete pile installation are presented in this paper. Based on authors’ field construction experience, this paper analyzes the key and difficult problems that may be encountered before and during the installation of bored piles, and the correspondent control measures are also proposed. This paper mainly evaluates the construction equipment staging layout, pile foundation positioning, slurry and sediment control, waste concrete control at the top of pile and other aspects, as a guide for the better pile installation practice.

Key words: bored piles, critical aspects, quality control measures
