Site attendance is the record of who was physically on a site, and when. Once a workforce is spread across more than two or three jobs it answers three questions that a weekly plan cannot: whether the people you allocated actually turned up, how many are inside the hoarding at this moment, and who is unaccounted for if the site has to be cleared.
Where is everybody is Unibuild's live site attendance map for UK contractors. Operatives start their shift by scanning a QR poster in your firm's own staff app, published on the App Store and Google Play under your company's name and icon. Each clock-in carries a location and a server-written time. The map plots the day's scans across every project you have running, each in its own colour with a headcount on it. It reads on a laptop and it has a television view for the office wall. It is built from scans and nothing else: no phone is followed between them. What each scan records is set out in QR codes on construction sites.
