Every worker can lead the casting table.
From the drawing set to the table, without anyone working out the order in their head.
Drop the engineer's IFC on the dashboard, or pick it from the plant's Google Drive, Dropbox or iCloud Drive. Nothing is redrawn.
Design analysis lists every bar, mesh, box and insert with its position, so the office sees what the table will need.
Production shows one step at a time on a tablet at the table: what goes in now, where, measured from the same edge as the drawing.
When the element is cast, one tick moves it to the archive. Statistics, faults and invoices stay in the office view.
The expensive part of precast is not the concrete. It is the mistake nobody sees until the element is cast.
precast production activities are classed as complex to learn. Placing embedded parts is one of them, and it stays the slowest of all fourteen, even for trained workers.
Tai et al., Int. J. Civil Eng. 2021, five years and 373,077 records from Taiwanese precast plants ↗of a contract was lost to one detailing mistake, the worst of 22 found across seven US precast projects: 75 spandrels cast too short. The precaster paid for it.
Sacks et al., PCI Journal 2003 ↗is what the US precast association says the same repair costs on the building site compared with in the plant. A mistake caught at the table is the cheapest one.
NPCA Architectural Repair Guide ↗of production cost and 7% of working time went into correcting defects on Swedish building sites in the 1990s, about twice the typical profit margin.
Josephson 1998, Chalmers, 7 projects, 2,879 defects ↗as many assembly errors with digital 3D step-by-step instructions on a screen than with paper, in a study of 66 people. Headsets that lay the steps over the work cut mistakes by 75 to 82% in two other studies.
Letmathe & Rößler, J. Operations Management, via Sirris; Tang et al. CHI 2003; Chalhoub & Ayer 2018 ↗Concrete placers and finishers are among Europe's ten most short-staffed occupations. New people will keep arriving at the table.
European Labour Authority, EURES report 2022 ↗No public study gives a precast reject rate, a cost per mistake or an onboarding time: plants keep those numbers inside. So we do not quote one. The pilot measures yours, mistakes per element and minutes per element, before and after.
Example values: type your plant's own. The share prevented is your assumption. In one study of 66 people, digital 3D step instructions on a screen halved assembly errors against paper; that was in another trade, so your pilot measures the real figure for your table.
The order of work stops living in one person's head.
Today a foreman reads the drawing set and decides what goes on the table first. When the foreman is on holiday, or the plant hires three new people, that knowledge is the bottleneck.
With 28bricks the order travels with the element. A new worker follows the steps on the tablet; the foreman checks instead of explaining. A five-year study of precast plants in Taiwan found that simple tasks take 4 to 26 days to learn, while placing embedded parts stays the slowest task even for trained workers. That is exactly the part the instruction carries.
At the table the controls are built for gloves: back, next place and next step sit in a bar at the bottom of the screen, buttons more than one and a half times the usual touch size. Everything else is one press away under Views.
Start with one plant and one real element.
A pilot runs for a month on the plant's own production, with terms agreed per plant. Send one drawing and you get its build order back the same day, free.
Bring one drawing. We show you its build order in an hour.
