Lessons Learned: CM at Risk & Design Build
CM at Risk UC San Diegos most used project delivery method is CM at Risk (CMAR). We have and continue to have great success with CMAR. Some examples follow…
CM at Risk – First CMAR project Eleanor Roosevelt Housing and Dining
Considerations for prequalification should include: Companys experience with comparable projects (comparable projects defined by owner). Companys experience with CM at Risk. (i.e. providing preconstruction and construction services as a requirement of the contract). Individual team members experience with comparable projects and CM at Risk.

Bidding Preconstruction and Construction Services At UC San Diego we establish the amount we will pay (lump sum) for the specified preconstruction services.
CM at Risk Skaggs School of Pharmacology & Pharmaceutical Sciences
We Recommend that Bids for Construction Services Include: OH&P (fee), CM/Contractors General Conditions and CM/Contractors General Requirements. We recommend that the CM/Contractors bid NOT include General requirements for the project. These costs are to be included in sub trade bids or bid separately. Specify a generous minimum for field staff. Dont be cheap! On a large project we require a Project Executive, a Sr. Project Manager, a Project Manager, three Project Engineers, a General Superintendent and two Superintendents (one structural and one for rough-in and finishes). The CM/Contractors bid shall include the costs of subcontractors payment & performance Bonds. Bonding subcontractors is the CM/Contractors option.

CM at Risk Cautions Look out for bundling of bid packages (Hard bidders do it less often). Beware of over prequalification – Limited bid pool increases price. Make sure CM/Contractor gets at least 3 bids per bid package. Be aware that CM at Risk probably costs 1-2% more than hard bid on bid day, although the final costs may be about the same. Starting Construction Phase before entire job designed and bid.

Design Assist (DA) and Design Build (DB) subcontracting with CM at Risk Cautions CM/Contractor must be sophisticated and experienced with DA & DB subcontracting on public works. It is expensive! There is the cost of CM/Contractors preparation of DA & DB bid packages and the costs of the subcontractors work during the preconstruction phase. It is Expensive! Have a clear understanding of the costs and benefits/deliverables. In Design Assist the designer remains the Designer of Record and the DA subcontractors are the peer reviewers. In Design Build the designer becomes the peer reviewer and the subcontractor becomes the Designer of Record.

Design Build First Design Build Housing Project - Miramar One Apartments
Design Build Advantages of Design Build Design Builder provides preconstruction services (like CM at Risk). Design Builder prequalifies subcontractors (like CM at Risk). Cost effective – the award is based on lowest cost per evaluation point. Overall quicker delivery – phasing / overlap of Design & Construction. Generally good relationships between owner, designer & builder.
Design Build The Villages at Torrey Pines – Apartments
Design Build DISADVANTAGES Design NOT completed when the project is bid. Exact project components loosely defined. May be more owner work involved than in other delivery methods. Changes cause havoc.
Design Build Cautions Must identify owner requirements that are above code (Code +). The program should be simple, i.e. Housing, Parking Garages (Design Build Proponents disagree!). A single, sophisticated client is preferred over multiple clients advocating different needs. Owner needs experienced staff and the time to review DB Proposals – becomes contract document. Owner needs experienced staff with the time to review design submittals quickly. Owner must realize that DB is just as much or more work than other delivery methods.
