What is the First Fix?
- The first fix refers to the initial stage of construction where the basic structural elements and essential services are installed. This includes everything that happens before the walls are plastered or covered, ensuring the foundation for the second fix is properly set.
- The first fix includes tasks such as erecting the structure, roofing, laying floors, and installing the necessary wiring, plumbing, and ventilation systems.
Key Tasks During the First Fix
- Structural Work: Erecting the main framework of the building, installing floors, walls, and the roof structure.
- Electrical Wiring: Running all electrical cables through the walls, ceilings, and floors, ready for outlets, switches, and light fittings to be installed later during the second fix.
- Plumbing: Installing pipes for water supply, drainage, and any central heating systems, such as underfloor heating or radiators.
- Ventilation Ducts: Installing any mechanical ventilation, such as ducting for MVHR (Mechanical Ventilation with Heat Recovery) systems, and preparing areas for bathroom and kitchen exhaust fans.
- Window and Door Frames: Fitting external window and door frames, although the actual windows and doors are installed later to avoid damage during construction.
First Fix Considerations
- Coordination: All trades need to work closely together to ensure that electrical, plumbing, and structural elements are installed without clashing, particularly when running pipes or cables through walls and floors.
- Inspection: Once the first fix is complete, inspections for building regulations (e.g., for wiring and plumbing compliance) should take place before the second fix can begin.
Importance of First Fix
- A well-executed first fix is essential for the smooth progression of the build. Ensuring all pipes, wiring, and structures are correctly installed will avoid costly modifications later on.
- The first fix also sets the foundation for the second fix, where the final finishes like plastering, painting, and fitting fixtures take place.
