First Fix

First Fix refers to the initial phase of construction or installation work in a building project. It includes essential structural, electrical, and plumbing tasks that are completed before adding finishing touches like plastering, painting, and fittings. In construction, the first fix involves installing frameworks, pipes, wiring, and other hidden components that lay the foundation for the final stage, known as the Second Fix. This phase is crucial as it ensures the essential systems are in place before aesthetic and functional details are added.
