Panhouse

A board for mill retrofit crews who are done living in a spreadsheet. Panhouse tracks the three lines that matter in a boilhouse — evaporation, crystallization, and packaging — from demolition through commissioning. Facility managers, process engineers, and contractors walk the same yard with different eyes. THE YARD • Three lines with sight-glass progress and a phase rail: demo, civil, mechanical, electrical, commissioning • Yard brix as a single number for how thick the finish is getting • A sample Gulf Coast Bay 4 retrofit you can learn on, or a quiet board you write yourself WORK TICKETS • Numbered stubs (PH-3412) with line, phase, hours, due date, and an assignee • Live, on hold, or struck. A hold reason sits on the stub • Filter the rail by status or by what is yours PUNCH • Hairline, process, or shutdown • Walk it, close it, clip a field photo from the camera or the library • The list that actually gets walked before first strike HOLD POINTS • Process gates on each line — hydro, vacuum, empty-bag trial • Clear them on the floor. When the pans are ready, the board knows CREW AND HANDOFF • Names, companies, craft, on-site or not • Shift logs with weather, headcount, and what the night left behind • Share a status brief when someone asks how the shutdown is going Everything stays on this iPhone.
