Sure thing. Break it into the classic phases: site prep, foundation, stone selection, lintel frame, arch shape, and finishing. For each, list a timeline and a checkpoint. Use a spreadsheet with columns for task, start, end, responsible, and a cell for the critical dimension—like the arch rise or the stone thickness. Add a 5% buffer to the key measurements, and lock that column so no one can change it without a comment. Put a colored flag on any milestone that’s overdue, so the whole team sees it at a glance. Stick to those dates, and you’ll keep the project humming.
