Engineering tools

Twenty tools on the estimate’s Tools tab. Three of them can be opened from a takeoff entry and send their answer back into it.

From the takeoff entry, and back into it

You are working in a takeoff module. A button there opens the tool with the run already in it. The tool runs, and from inside it you send the result back — and it lands in the entry you came from, because the entry launched it. The tool never reaches into the estimate: the entry hands the tool its context. Values that came back show in green; type over one and it is yours, and the next import leaves it alone.

Conduit (Feeder / Branch Circuit)⚙ Size from FillConduit Fill, with the run’s conductors and conduit typeSend this Fill to Takeoff: the conduit size. Send Recommended or Send As Designed to Takeoff: the conduit size, the phase conductors, the neutral if the run has one, the ground and the number of parallel conduits.

The other way: in the Pull Tension tool, Read from takeoff copies a conduit run from the estimate into the tool and changes nothing in the takeoff; Add to equipment list puts the cable puller and rope on the estimate’s Equipment tab. The other tools are reference and calculation only: the Tools tab says they do not affect the takeoff or the bid.

The twenty tools

Each tool shares one toolbar: Name / Tag, Save Report (PDF), Save Calc, Load Calc, Open phone job… and Reset This Tool. The fourteen linked below each have a page: the drawing the tool makes, the report it writes, and its example step by step in the Suite.

  1. Conduit Fill

    Chapter 9 fill and the smallest conduit, with ampacity and derating, voltage drop and feeder sizing on the same screen.

    Sends back to the takeoff
  2. Pull Box

    314.28 box size for straight and angle pulls of 4 AWG and larger, drawn to scale.

    Sends back to the takeoff
  3. Wireway

    Wireway and gutter fill at 20 percent: 376.22(A), 378.22 and 366.22(A).

    Sends back to the takeoff

The same calculations run on a phone in Stinger Pro Tools, the Android app; Open phone job… opens a job saved in the app for eight of the tools, and the Suite works the answer out again.
