A revolution in the construction industry: Change Order Free.

The German term „nachtragsfrei“ means „no supplementary claims“.
We have named our association after this term, because it concisely
states our aim. nachtragsfrei is an association of business people
in the field of building and construction.
It is the sole aim of the association to free building projects of
the burden of supplementary claims and make this the industry standard
when it comes to all construction in existing commercial buildings.
In order to achieve this, the association has formulated a set of
„Change Order Free Construction“ (CoFC).
These principles aim to guarantee that the initially projected returns
are actually realized for the principals. We believe the following
axiom should always apply: r = E(r).
