From my experience working exclusively in the public realm in 27 states, when CMs are part of a project they become a partner. First question is purpose and mindset so that "rules of engagement" are understood and clear. CMa more as a service (Owner first) CMc more as a general contractor (Subcontractors first). It is what it is but context is important. Then there is the question of impact to the design process (pre-bid). Most (VPs not BDs) will indicate there isn't a difference. Everything is bid and "open book". Under CMc how open needs deeper discussions as well as "self-performance" and can/ can't do. This also adds context to the "rules of engagement". None-the-less this provides path to align B132 with B133 when it comes to involvement of the design firm in procurement (cut / paste from 132 to 133). This also provides the path for establishing roles and responsibilities for VE at the end of each design phase (minimum). Value analysis provided to the Owner that includes scope of work and estimate provided decisions making based on value versus expense. It also, keep the Owner engaged so that the project is meeting their needs versus those of the design team or CM. This is important conversation early so that the purpose of a GMP can be discussed. This starts with the client 1. has a budget in mind and asks the design team "what can I get for this much money" or 2. a need and/or ideas. In either case PD brings them together. The PD deliverable provides the Owner the opportunity to digest and become a vital part of aligning budget with scope of work. As the designer, it is an obligation to design to the budget. When, in most of my cases, the public institution accepts the PD Alignment Report, a "design GMP" is established. Regardless of delivery vehicle, contracts and practice have multiple vehicles for adjustments up / down but premise remains the same. With everything above established, then the question isn't so much as the need for a GMP but when it is provided.
If it is true what CMs say "CMa or CMc starts with bid recommendation" and the design team commits to the "design GMP" then seldom does the conversation end with a need for a GMP prior to providing 100% CDs, bidding, scoping bids (notes of which become part of construction contract) and award of construction contracts. I am starting to see an increase in a two-step award where the first authorization is a draft of the GMP along with motion to issue NTPs so that contractors can begin transitioning operations from "penciled" to "inked". The Conformed set is issued as soon as possible after scoping meetings along with individual NTPs, draft contracts, etc. With conformed set issued and accepted (10 calendar days to "speak now") then the draft GMP becomes final and issued to the public entity for formal acceptance of the GMP and if available construction contract approval for signature.
I share because this has worked for me in the past but took significant time to establish a means for consensus with the CM and Owner. I also understand this is easier said than done - absolutely. It takes much more than what I have shared above but I hope you get the gist.
ThenThis step provides the path for discussing the need for GMP.
The difference comes with "the recommendation letter to award" under CMa or "GMP" under CMc.

Subject: How to Address CM's Assumptions & Clarification in a GMP SUbmittal
In a recent Construction Contract Administratiuon Knowledge Community thread about documents and order of precedence, Dennis J. Hall, FAIA, had a comment about the CMA@R's GMP attachment of Assumptions & Clarifications (A&C's). If not poperly addressed at the beginning of a project of how the A&C's will be developed and reviewed at pricing checks through design phases there will be potentially big surprises in the final GMP package that can result in lesser quality, reduced program/operations, and/or result in A/E team Additional Service Requests to revise the drawings and specs.
Do others of you have experiences and input and comments on this topic? I have not come across any CEU sessions on this topic - have you?
It is my understanding that If the Owner accepts the submitted GMP with the CM@R's A&C's, the final A/E reviewed, negotiated and accepted A&C's should be explicitly attached to and incorporated in the GMP Amendment to the CMAR contract.
It is my understanding that without specific incorporation, the General Conditions and the A/E's drawings/specifications take precedence in interpreting scope and requirements.
Again, do others of you have experiences and input and comments on this topic?
