Progress Update on the Column Repair at LIFE Ladprao Valley:
Latest Update (March 30, 2025): Today, government officials visited the LIFE Ladprao Valley project site. The team included: • Bangkok Metropolitan Administration (BMA) Department of Public Works • Chatuchak District Office of Public Works • Construction experts from the Engineering Institute of Thailand • Associate Professor Sub-Lt. Dr. Supachai Sinthavorn, Associate Professor in the Department of Civil and Environmental Engineering, Faculty of Engineering, Srinakharinwirot University, one of the members of the inspection team.
The visit was to inspect the progress of the structural repair work. All involved parties have acknowledged and agreed on the repair steps and procedures currently being carried out. The method being used is “Jacketing Column”—encasing the existing column with a newly cast concrete jacket, designed based on structural engineering calculations.
Completed Steps: 1. Sealed the area with fiber-reinforced cement to prevent the epoxy pressure grout from leaking during injection. The purpose of the epoxy injection is to fill and bond small cracks in the original concrete. 2. Installed formwork and poured high-strength, non-shrink premixed mortar to restore the original cross-sectional area of the column.
Ongoing Step: 3. Reinforcing the column with 25 mm thick steel plates, wrapped around the column to a height of 3.60 meters from the floor.
Next Steps to be Carried Out: 4. Inject epoxy pressure grout between the steel plates and the original concrete. 5. Further reinforce the column by increasing its cross-sectional area by 15 cm on each side. This includes installing 24 reinforcement bars (20 mm diameter), tied with stirrups (12 mm diameter) at 20 cm spacing, and pouring concrete from the footing up to the top of the column beneath the 3rd-floor slab.
All parties have been working on the repairs since the day of the earthquake, involving a team of AP engineers, third-party experts, senior structural engineers, and contractors. The entire repair process is expected to be completed by April 4, 2025, following sound engineering principles.
