What travels is the standard: how a heater is sized, how end grain is sealed, how a membrane is detailed into an existing wall, how a chiller is matched to real ambient rather than a chart, how loads are sequenced onto a generator, and what a quote has to show before we will send it.
What does not travel is the specification. A4 stainless and drained cavities on a coast are waste money in Marrakech. A harmattan dust package matters in Abuja and is irrelevant in the Seychelles. An altitude correction that is essential at the Ngorongoro rim would be an error at sea level. So we write eight specifications and one standard.
It is also why our price tables are per country rather than continental. Shipping, duty, access and local trades move the number more than the cabin does, and pretending otherwise is how a quote grows after it has been accepted.
