The project consists of Chemical Plant Extension to produce polypropylene included in the tire composition. Menard Asia is in charge of Controlled Modulus Column (CMC) & Stone Column (SC) realization (ground improvement method) by pouring columns, injecting mortar, predrilling, and compacting stone.
Menard Asia scope of works:
- Organize Soil Investigations and design the ground improvement for the Contractor
- Perform CMC ® & Stone Column on 8 areas
- Provide the Contractor with PLT (Plate Load Test) – testing method for CMC & SC
- Level finalization with sand layer for LTP (Load Transfer Platform)
The ground conditions in this area were totally different from one area to the other. Menard Asia has treated 8 major areas subdivided in zones to get the most optimized design. There were compacted sands with a hard layer around 2,.5 m depth until 7 m. Then, some areas were composed of soft clays (brown and green) and sandy clays with a hard layer from 6 m up to 8 m.
Menard Asia’s solution for this project was Controlled Modulus Column (CMC) & Stone Column (SC) to treat 12,105 m² in Cilegon, Banten, Indonesia.
