• Electrical Tool Set

  • Rapid Estimating Tool

    • A dynamic tool for generating fast and accurate cost estimates for large-scale data center projects. It automates complex calculations and integrates a modular database of component costs, enabling real-time adjustments and scenario analysis. This system significantly reduces estimation time, improves bid accuracy, and supports faster decision-making for projects of any size.

  • Commodity Price Tracker

    • This tool automatically pulls and logs daily pricing for key materials like copper, aluminum, steel, and PVC. It provides a reliable historical data source for material costs, which feeds directly into the Rapid Estimating Tool for precise, real-time pricing. The system improves forecasting, mitigates financial risks from market volatility, and enhances bid accuracy and profitability.

  • Mechanical Equipment Load & Feeder Sizing Tool

    • A semi-automated solution that simplifies the complex process of calculating electrical loads for mechanical equipment. The tool automates all necessary calculations, including feeder sizing, circuit breaker selection, voltage drop, and ambient temperature adjustments. It uses NEC lookups and user inputs to ensure designs are code-compliant, reducing human error and saving significant time on complex electrical designs.

  • Conduit Fill & Sizing Tool

    • This tool simplifies the process of calculating conduit and raceway fill for various wires. It accounts for various wire types (copper and aluminum) and insulation ratings, from 600V up to medium voltage, across all raceway types (EMT, RMC, IMC, PVC, etc.). The tool automates calculations based on NEC and other relevant standards, ensuring compliance and preventing overfill. It significantly reduces design time, minimizes the risk of code violations, and optimizes material selection for both new installations and retrofits.

  • Generator Sizing Calculator

    • This comprehensive tool automates the process of sizing a generator and planning its fuel logistics. It calculates the optimal generator size based on current and future demand while also determining fuel tank size and refueling schedules based on runtime and load. This system eliminates guesswork, reduces operational risk, and prevents costly errors in equipment procurement and project planning.
