Technical Notes
Technical notes on steel quotes, model coordination and site erection.
File, offcut and measure in laser cutting
Cutting starts with a clear file, not machine speed. If offcut, measure and piece marks are not closed before the cutting order, the shop cuts the last conversation — not the right drawing.
Steel waits if the anchors are not ready
The column base is closed before the concrete. Without anchor drift, level and axis written down, the truck does not enter the plot — steel that arrives becomes stock, not erection.
Why tonnage alone is not a steel quote
The same tonnage can mean very different work. A price without crane loads, connection type and site constraints is a guess, not a scope.
Close clash checks before fabrication starts
A clash closed in minutes in the model costs days once plate is cut. A Tekla handover is a coordination record, not a green light for the shop.
