After the contestants were given time to design the control and power portions of the commercial kitchen from the description, their designs were collected and the "judge's" design was passed out. This allowed those who were unable to correctly design the project an even chance of building the project from drawings.
The workspaces were 4x4 plywood sheets mounted with a plug-and-cord connected edison socket in a 4x4 box and 2 neutrals, a ground, and 1 black and 1 red hot wire extending from the box. Paper tags were stapled to the plywood indicating placement of devices. Each workspace also had a plastic storage box filled with all the components and wire needed to complete the project. "Distractors" in the form of extra wall switches and pushbuttons were also in the storage box.
The judging broke the project score down into 7 elements: power circuit 25, On-Off control 55, Stop-Start 55, Fire Alarm control 70, Run-to-Destruction 65, component placement 50, and neatness (workmanship) 50 for a total of 370.
Partial credits were given for many elements.
The power circuits were evaluated both by operating the control circuits and, if that failed, by manually closing the contactors.
The On-Off and Stop-Start control circuits were tested by operating the switches / pushbuttons and observing the operation of the contactors.
The Fire Alarm control was tested by operating the Fire Alarm switch and observing if it correctly overrode the settings of the On-Off and Stop-Start control circuits.
The Run-to-Destruction was checked by visual inspection.
The Placement of several components was checked against the stapled labels.
Neatness was checked by looking for level components and wiring done in vertical and horizontal orientations rather than "point-to-point".
