What you need before you start

Before coordinating subcontractors, have the work plan, crew contacts, task order and communication method ready. Make sure each subcontractor knows what work is expected, who gives updates and how changes will be shared. For crane work that uses OperatorLink, the crew joins one jobsite session in a phone browser, with someone sharing a link or QR code. [1] [1] Confirm that each phone has a working browser because button presses, chat and voice pass between phones in a browser. [1] Decide how the crew will handle STOP, HOLD and SLOW before the lift begins.

Step by step

  1. List each subcontractor, the work area and the person responsible for updates.
  1. Set the order of work so crews know when their tasks start and what information they need before moving ahead.
  1. Choose one communication method for routine updates and urgent signals. OperatorLink can be used from a phone browser with no app install needed. [1]
  1. If using OperatorLink, the person who starts the jobsite shares a link or QR code, and the crew joins from it. [1]
  1. Confirm every crew member is in the session before work begins, so each one sees the same signals. OperatorLink shows STOP, HOLD and SLOW to the jobsite crew. [1]
  1. Agree on how signals are used. HOLD and SLOW stay on for everyone in the jobsite and are cleared when the last person leaves. [1]
  1. During a move, holding a move button keeps sending that move to the other phones, and if it stops arriving for 2 seconds, they drop it. [1]
  1. Review completed tasks and open items with subcontractors before the next work stage begins.

Tools that can do it

OperatorLink is made by the team that publishes this site. It shows STOP, HOLD and SLOW to the jobsite crew and passes button presses, chat and voice between phones in a phone browser. [1] Nobody needs to install an app; the page runs in a browser. [1] The person who starts a jobsite shares a link or QR code, and the crew joins from it. [1]

A phone video call app is another option. No facts here describe one, so check whether the crew can keep the call open, whether the needed views stay available and whether the communication method matches the work.

A two-way radio is another option. No facts here describe one, so check that the crew agrees on how messages are shared and that the channel works for the site.

For phone-based coordination, OperatorLink also lets anyone who joins take part in a voice call run from the phone browser. [1] One-tap radio-style calls such as Go Ahead, Copy That and All Clear are sent as chat messages. [1]

Common mistakes to avoid

Starting work without confirming who gives updates can leave subcontractors unsure about changes. Set the communication plan before tasks begin. Assuming every phone handles alerts the same way can cause confusion. On Android browsers, signals such as STOP make the phone buzz; iPhone Safari ignores the buzz. [1] Leaving an empty OperatorLink session open can remove the session after idle time. A jobsite with nobody in it is wiped after 3 idle hours. [1] Forgetting that HOLD and SLOW stay on for everyone until the last person leaves can create delays when the crew expects them to clear. [1] Not checking that a move signal continues arriving can create confusion because if it stops arriving for 2 seconds, the other phones drop it. [1]
