Why the cheapest industrial quotation often costs the most
Not an argument for paying more. An argument for comparing quotations that actually cover the same work.
Scope gaps are not found during tendering. They are found on site, at the worst moment, and somebody always pays for them.
A scope gap is work that everybody assumed somebody else was doing. It is not dishonesty. It is the predictable result of a BOQ written from one side’s point of view.
Between trades. The civil contractor casts the foundation, the mechanical contractor installs the machine, and nobody has grouted the base plate.
At the utility boundary. Cable laid to within three metres of the machine, because the drawing stopped there.
In the word “supply”. Supply, supply and install, supply and commission, and supply with training are four scopes. BOQs frequently say only the first and expect the last.
In disposal. Old machine removed. Removed to where? Scrap disposal, gate pass, transport and weighment are real cost.
In reinstatement. Floor made good, area cleaned, temporary works removed. This is always assumed and rarely written.
In supervision hours. A job priced for day shift, executed across nights and a Sunday.
The last question matters most. Every industrial project meets something unexpected. What separates a controlled project from a disputed one is whether the decision route was agreed before the surprise, or invented after it.
Not an argument for paying more. An argument for comparing quotations that actually cover the same work.
Why fabrication quotations vary so wildly between vendors, and the six inputs that make them comparable.
