If you are preparing for exams or practical work, the core chapters include:
| Pitfall | Consequence | Prevention | |---------|-------------|------------| | Under‑estimating conduit length (ignoring vertical runs) | Cost overruns | Use 3‑D modeling or a “run‑sheet” that lists every floor‑to‑floor segment. | | Forgetting to include waste factor (usually 5‑10 % for cable) | Material shortage | Apply a waste multiplier to each cable line‑item. | | Using outdated labor rates | Low‑ball bid → loss | Update rate matrix quarterly. | | Missing permit fees | Project delay | Add a “Permits & Inspections” line‑item (often 1‑2 % of total). | | Ignoring inflation (especially for long‑duration projects) | Profit erosion | Include an escalation clause (e.g., CPI‑linked). |
