The software
Built for the EC. Read by the GC.
ShefaLinx is the job tracker an EC runs on their own crew. When they do, the milestone dates and manpower numbers are the same ones I check in an audit — real-time instead of after the fact.
ShefaLinx
Milestone and manpower tracking an EC runs, a GC can trust.
Punch lists, manpower, and roadblocks in one place, built by superintendents for superintendents. When an EC runs it, the GC gets real numbers on power-on, air-on, and temp removal — instead of finding out at the OAC meeting.
- Milestone tracking for power-on, air-on, temp removal, and any other date the schedule hinges on
- Live job dashboard: tasks open, blocked, man-hours, and percent complete
- Roadblock flags — design/RFI, predecessor, sequencing, change order, trade stacking
- Completion lists with photo uploads, tied to the task
- Workday length switching between 8, 10, and 12 hour days
Manloader
Turns the schedule into a weekly crew loading chart with real labor cost, and flags the week a crew falls short before that shortfall costs a milestone.
Field Calculators
Duration, install quantity, conduit per 100 ft, wire per 1000 ft, crew hours, and install goals — run on the phone, in the field.
Completion Lists
Punch items assigned by trade with due dates, photo evidence, and a closeout report generated from what the crew actually logged.

Live demo
The manpower math, without installing anything.
This is the same crew-vs-schedule calculation Manloader runs, plus the voltage drop and conduit fill checks the field uses daily. Change any input and the numbers update as you type.
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's built this way
Three rules ShefaLinx has to follow.
Construction software has a reputation for being slow, bloated, and clearly designed by someone who has never worn a hard hat. These are the rules that keep it from going the same way.
Milestones, not just tasks
Power-on, air-on, temp removal, or any date the schedule hinges on — tracked against real progress, not a percentage someone typed in.
Works with no signal
Job sites are basements and steel decks. Every calculation runs on the device, so nothing depends on bars.
Manpower, checked against the date
Manloader flags the week a crew falls under what the finish date requires — before that shortfall costs a milestone.
Where the proceeds go
Built for the superintendent. Sent to the mission.
ShefaLinx exists to solve a real problem in the field — nothing more complicated than that. What it earns is a separate matter: the proceeds from ShefaLinx go to community outreaches and crusades.
“And he said unto them, Go ye into all the world, and preach the gospel to every creature.”
Mark 16:15, KJV
“Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.”
Matthew 28:19–20, KJV
“For whosoever shall call upon the name of the Lord shall be saved. How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher? And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!”
Romans 10:13–15, KJV
