Dear All,

We have a 300,000sqft project, quite technical facility.

It is a design&build contract and the owner is reluctant on taking independent contracts on his own. In addition, even if he would like to, the process of contracting would take lots of time according to him due to language issues as well as exchange process with the branch of his which is doing the project.
Therefore, the solution, which has been considered is that the Design&Build company first makes a global contract for the CxA, which includes the base scope of commissioning that is required for this facility and the enhanced commissioning scope as per LEED.
Then, they want to make a change of order which places the LEED scope under the owner leadership and for that part, the CxA must report directly to the owner. Ultimately it is the owner who will pay the CxA for this part. This scheme has been imagined to bypass the slow contracting and also the reluctance of the owner to separately contract.
The other reason is the timeline, since they lost lots of time debating about it and were more focused on other design issues, the 50%CD milestone is now, meaning we must hire the CxA now to have the OPR and BOD reviews done in a timely manner.

Can someone help us know if this strategy can be eligible and if there is any issue with it?
Also, what is the tolerance in time about the 50%CD stage in the project? This "moment" in the process is sometimes not easy to define accurately. Does someone has the exact definition of this milestone?

This facility would really benefit from enhanced commissioning, we believe we can demonstrate easily the positive impact of CxA as an additional voice in the dialog. We are just a bit unsure about the above from the formal point of view.

Thanks all for your help.
