## Scope

Illinois, United States. The bricklayers' union journal describes the P-714 barracks at Naval Station Great Lakes, where union members laying concrete masonry units used the MULE lift-assist arm, with 12 machines working across the site at its peak; the contractor's foreman says the mason's skills are still needed and the machine makes the site safer and more productive, and the union's secretary-treasurer says its use is limited by building design and site coordination. One project described by the union; it reports no change in crew size or hours, and the units were heavy block, not ordinary brick.

## What this means

On real sites, robots take the lifting of heavy block while the mason still places each unit.

## What it does not show yet

One project, heavy block only, and no figures on crew size or hours.

## How to verify it yourself

Open the BAC Journal article 'Timeless Masonry with a New Technological Assist' and find "12 MULEs working across the site".
