Emergency repair on a bogie hearth furnace
What is inside only shows once it is open
Initial situation
A bogie hearth furnace in a plant builder's workshop needed its refractory lining repaired at short notice. The enquiry came in on a Monday, by e-mail and by phone. On Tuesday at eleven, two fitters were standing at the furnace. Nobody could say beforehand exactly what needed doing — that is decided once the furnace is open.

Project data
The task
The refractory scope cannot be fixed before the inspection. A fixed price would either be pitched too high or turn into a claim at the first finding
A bogie hearth furnace is not lined from one side: hearth, bogie, walls and door each expand differently and have to match one another
Short notice applies to the crew as well — accommodation, travel and material had to be in place within a day
Two trips were foreseen. If the first one slips, everything behind it slips with it
The SBS approach
What was offered was a cost estimate billed by actual effort against time and performance records — explicitly so, because the scope would only be known on inspection. An additional finding therefore became a line in the record rather than a dispute.
Two fitters, one contact, one continuous crew. Both trips ran into each other without a single day's break.
The start was promised to the hour and kept: Tuesday, eleven o'clock, one day after the enquiry.
Every shift went into the performance record. The customer could follow what the findings cost as it happened, instead of receiving a lump sum at the end.
