Foundation Works

Establishing a solid foundation is critical. This involves excavation, laying footings, and constructing base slabs to support the structure above.

Structural Framework

Erecting the main structural elements, such as beams, columns, and floors, forms the building's skeleton, ensuring stability and load-bearing capacity.

Enclosure and Roofing

Installing external walls, windows, doors, and roofing systems encloses the structure, protecting it from environmental elements.

Interior Fit-Out

This phase includes installing internal walls, ceilings, flooring, and finishes, as well as integrating mechanical and electrical systems to make the building functional.
