Field software for superintendents and management
Built for superintendents, by a superintendent.
ShefaLinx puts the job tracker, pre-energization checklists, job hazard analyses, and field leadership org charts in one app — made by a Master Electrician with thirty years running electrical crews, and used on real jobs.

What's inside ShefaLinx
Four tools, one login, one job at a time.
Each one solves a piece of paperwork a superintendent already does — faster, on a phone, and in a form management can read.
Who it's for
The person doing the work, and the person who needs to see it.
A tracker only works if the field actually uses it. So it's built to be quick for the superintendent — and the numbers it produces are the ones management has been asking for.
For the superintendent
- Track every punch item with crew, days, and man-hours — the schedule math is done for you
- Load the crew against the finish date with Manloader, and run conduit fill and voltage drop on your phone
- Fill out a JHA in minutes and have the crew sign on their own phones
- Check pre-energization conditions off equipment by equipment, not just per job
For project management
- Power-on, air-on, and temp removal tracked against real progress, not a typed-in percentage
- A live dashboard: tasks open, blocked, man-hours, and percent complete
- Roadblocks flagged as they happen — design/RFI, predecessor, sequencing, change order, trade stacking
- A field leadership org chart for every job, with a PDF on demand
What Manloader shows
A shortfall you can see three weeks out.
This is the screen a superintendent looks at — man-hours logged, roadblocks open, and crew loaded against capacity, week by week.
Man-hours logged
Open roadblocks
1 week flagged
Manloader caught the shortfall three weeks before the crew was due on site — early enough to actually do something about it.
Manloader
Weekly crew loading
Flags a shortfall while there's still time to add crew or resequence — not after the week is gone.

The field math, running live on this page.
These are the same calculations built into ShefaLinx — crew against schedule, voltage drop, conduit fill. Change the inputs and watch it move.
Within the 3% recommended in NEC 210.19(A) / 215.2(A).
VD = √3 × 12.9 × 210 A × 240 ft ÷ 250,000 cmil
Reference calculations for estimating and checking your own work — not a substitute for a stamped design. Values follow the 2023 NEC; confirm against the code cycle your jurisdiction has adopted.
Why it exists
I built it because I needed it running my own jobs.
Milestones were getting missed because manpower was guessed at instead of calculated, and the only signal upstairs was a verbal update. ShefaLinx is the fix I wanted — built by a Master Electrician, tested on real crews.

The demo runs in your browser — nothing to install and no account. Add a punch item, load a crew, fill out a JHA. When you're ready to run your own job on it, tell me what you need.
