Every reliable electrical installation begins with the part nobody ever sees: the conduit network buried in slabs and walls. Conduits protect wiring from moisture, impact and heat, and they make future rewiring possible without breaking structure. Get the conduit stage right and the building's electrical system stays safe and serviceable for decades.
Disciplined conduit work starts on paper. Approved shop drawings and conduit layouts are prepared before execution begins, so every run is coordinated with structural, plumbing and HVAC services. On fast-track MIVAN projects, slab conduiting must keep pace with slab cycles of six days or less — which is only possible when routes, drops and junction points are planned in advance.
On site, the essentials are simple but non-negotiable: use ISI-marked conduits of adequate size, keep bends gentle and minimal so cables can be drawn without damage, secure conduits firmly before concreting, and leave draw wires in place. Junction boxes must remain accessible, and slab conduiting should be inspected and cleared stage-wise before every pour.
After casting, each run is proven clear, cables are drawn — never forced — and circuits are meggered for insulation resistance before termination. That stage-wise inspection record is your quality trail: it is how we ensure what is hidden inside the concrete is as sound as what you can see.
Key Takeaways
- Plan routes with approved shop drawings before execution
- ISI-marked conduits, gentle bends, draw wires left in place
- Stage-wise inspection before every slab pour
- Insulation-resistance testing before termination
