Construction of an excavation pit for Venice Grand Canal Mall

In the financial and lifestyle district of Bonifacio Global City (BGC), the Venice Grand Canal Mall is constructed. The entire BGC district used to be a part of the main Philippine Army camp and experienced commercial growth following the sale of military land. Along with this development, the three-storey lifestyle mall with three basement levels was conceptualized. Bauer Philippines was tasked with the construction of the excavation pit for the building. The original scope of works awarded consisted of diaphragm wall with ground anchors. However, the secant pile wall was proposed and designed by Bauer to be able to execute the shoring from several different elevations and to account for numbers of corners and curved alignments of the wall, considering that it is lying near the building’s boundary line.
A total of 452 secant piles with 880 mm diameter and maximum depth of 22 m were constructed using BG 15 and BG 30 drilling rigs, to serve as a pile wall for the retaining structure. In addition to this, our experts were responsible for the installation of 550 ground anchors, as well as construction of capping beams and waler beams.
