Mission
Deliver work that is robust, safe, and verifiable, within a cost-effective budget and timeline.
Our Services (Service Portfolio)

Foundation & Pile Work
- Micro Pile for constrained sites, low vibration, suitable for buildings in operation.
- Bored Pile Ø 30–120 cm, depth up to ~30 m, for large buildings/bridges/resorts.
- Underpinning to lift/strengthen existing foundations without business interruption.
- Load Bearing Calculation performed by registered structural engineers.


Retaining Walls & Earthwork
- Reinforced-concrete retaining walls (L-/T-shape), gabion systems.
- Filling, Compaction, Drainage around slopes/canals/coastlines.
- Design & calculation of earth pressure plus drainage to prevent hydrostatic pressure buildup.


Hotel & Resort Renovation
- Structural upgrades without halting operations (NDT diagnostics → phased zoning/work-window planning).
- Extensions/expansions (additional floors/wings using Micro/Bored Piles as appropriate).
- Building Code upgrades: structure, escape routes, fire protection, and MEP to pass inspections.
- Tropical design: moisture/salt-spray-resistant materials, drainage & ventilation, energy-saving solutions.


Structural Strengthening
- Carbon Fiber Reinforcement (CFRP): increases flexural/shear capacity of beams, slabs, and columns.
- Steel Plate Bonding: boosts capacity for industrial structures/heavy-duty loads.
- Epoxy/grout injection for cracks and concrete void remediation.
- Modern diagnostics (NDT): Rebound Hammer, UPV, GPR, Thermography, Crack Monitoring.


Passenger Lift (Specialized)
- Spring/parts replacement and passenger-lift servicing.
- In cooperation with K & L Associates Co., Ltd., under building-safety standards.
