On February 15, the first bored pile of the Macau Organic Resources Recovery Center project, undertaken by The First Engineering Bureau of CREC, was successfully poured, marking the official commencement of the full-scale bored pile construction phase.
The Macau Organic Resources Recovery Center project includes a total of 178 bored piles, with 121 piles having a diameter of 1.8 meters and 57 piles with a diameter of 1.2 meters. The successfully poured pile, designated as 1-P017 for the administrative building, has a diameter of 1.2 meters and a length of 69.88 meters. The construction was carried out using the underwater tremie method.
The project faces multiple challenges, including complex geological conditions and long pile lengths. To ensure the successful pouring of the first bored pile, the project team optimized the construction plan comprehensively. For the upper section, they used a fully rotational steel casing installation combined with grab excavation technology. For the lower section, a slurry-supported rotary drilling method was adopted. Additionally, the team refined procedures in areas such as technical briefings, acceptance processes, personnel and equipment allocation, and material supply. Responsibilities were clearly defined to guarantee construction quality.
