The backbone of modern infrastructure relies on precise, safe, and robust electrical systems, particularly within challenging environments like tunnels and underground routes. We are pleased to present a case study from a recent deep infrastructure project: the High-Voltage Conduit & Cable Route Project delivered by True Bid Data.
The Challenge of Underground Estimating
Estimating in underground or tunnel environments presents unique challenges that exceed standard commercial projects:
- Complex Logistics: Accounting for material delivery, storage, and handling within confined spaces.
- Safety and Compliance: Adhering to strict regulations for high-voltage installations and fire safety in tunnels.
- Route Geometry: Accurate takeoff for conduit runs that navigate tight curves, vertical shafts, and long-distance paths.
Precision for High-Voltage Systems
This project required specialized estimating for high-voltage components, which demand zero tolerance for error. Our estimate covered the full scope of the electrical routing system:
- Conduit Installation: Precise quantification of metal and PVC conduits, fittings, hangers, and supports required along the entire route.
- Cable Route Mapping: Detailed mapping and measurement of the various cable trays, ladders, and trunking systems designed to secure the high-voltage lines.
- Cable Quantity Takeoff: Accurate measurement of the kilometers of high-voltage cable required, accounting for sag, termination lengths, and waste factors.
True Bid Data: The Foundation of Success
The successful delivery of this project estimate by True Bid Data hinged on our ability to translate complex engineering drawings into a reliable financial roadmap. We ensured:
- Risk Mitigation: Identifying potential conflicts and material overruns before construction began, a critical step in high-cost infrastructure.
- Material Optimization: Using 3D modeling and digital takeoff tools to reduce waste in conduit and cable lengths, saving significant cost.
- Subcontractor Confidence: Providing a crystal-clear Bill of Quantities (BOQ) that allowed electrical and civil subcontractors to bid with confidence.
By delivering this detailed and precise estimate, True Bid Data established the cost baseline for a vital piece of infrastructure, ensuring the project moves forward with financial clarity and technical integrity.
