indeed. if you bid something off 10 year old as builts, you deserve what will happen to you.
a project management group who shall remain nameless, did a green book exclusion preventing
renegotiation of contract pricing for dewatering excavation, specifying a fixed amount per gallon
of groundwater treated, and not modifiable by either party. green book contracts for public works
allow renegotiation of an item by either party if the unit amount changes by more than 25%.
this allows for unforeseen occurrences.
they did this based on a ten year old water table survey of the property, thinking my company
would not even be able to recover the cost of setting up carbon filters and baker tanks. they figured
total water treated to be < 100k gallons. for the entire project. i mean, there is this survey,
showing the water table waaaaay down there..... what could go wrong?
yep. they showed us. however, things change. including the water table.
at the peak of dewatering, we were running two 6" diesel pumps full boat, treating about 400,000
gallons....
per day.
at a fixed, non negotiable amount. it was a $25M project total, and the profit on treating the water
poured down the drain was more than the profit on the entire job, by an order of magnitude.
took a lawsuit, and three years to collect, but at the end of the day......
