Pile Design and Construction at the Opera Residences in Ho Chi Minh City, Vietnam—A Case Study
Publication: Geo-Congress 2023
ABSTRACT
A new project consisting of three basements and 24 floors of luxury residential and commercial complex is developed in the Thu Thiem New Urban, Ho Chi Minh City, Vietnam. It is located next to the bank of the Saigon River which presents adverse geological conditions, including the top 23 m of backfill and very soft clay layers. To optimize the pile design for the project, the Design consultant proposed six piles of various diameters and lengths, including three shaft-grouted and three plain piles, and subjected them to static load tests. The resulting load-settlement curves indicated that the capacities of the shaft-grouted piles were significantly enhanced by this technique. In addition, the readings from strain gauges showed the advantage of shaft-grouted piles in terms of mobilized shaft resistance through different geological strata. As a result, shaft-grouted pile was selected for the final design of piling works to decrease the total pile length, thus reducing construction time, costs, and carbon emissions.
