Navigating the Different Project Delivery Methods: Understanding the Pros and Cons
When it comes to designing and constructing a building, there are many different project delivery methods to choose from. Each method has its own set of advantages and disadvantages, and it’s important to understand the differences between them to make the best decision for your project. In this article, we will explore the different project delivery methods, including Design Bid Award, Construction Manager as Advisor, Construction Manager as Constructor, Design Build, Integrated Project Delivery (IPD), and Conformance with Sustainability Requirements. We will discuss the benefits and drawbacks of each method, and provide examples of when each method is best suited.
Project Delivery: Design Bid Award Method Explained
The Design Bid Award is like a big contest. Architects, who are the people who design buildings, put out a call for contractors, who are the people who actually build the buildings. Contractors then put in a bid, which is like a proposal for how much they will charge to build the project. The architect chooses the contractor with the lowest bid, meaning the cheapest proposal.
There are some good things about the Design Bid Award method. For one, it’s a fair way for owners to choose a contractor because everyone has a chance to bid. And, the owner gets to pick the cheapest proposal. But, there are also some downsides to this method. Sometimes, the process can create a bad relationship between the owner and contractor, because the contractor wants to make as much money as possible, and the owner wants to spend as little as possible. Also, the price of the project can end up going up as the project goes on.
There are other things to consider when using the Design Bid Award method too. For example, public projects usually need to have a notice in the newspaper telling people that the project is up for bid. And, there are often changes made to the project before work begins, so the owner and architect needs to let the contractor know about those changes. And, the contractor needs to provide some kind of guarantee that they will finish the project and that they have the money to do it.
Overall, the Design Bid Award method is a way for owners to choose a contractor for their construction project that is fair and cost-effective. But, it’s important to be aware of the potential downsides and make sure to address them throughout the process.
Project Delivery: Construction Manager as Advisor (CMa) Explained
Construction Manager as Advisor (CMa) is another way to handle construction projects. In this method, the owner of the project works closely with a Construction Manager (CMa) throughout the design and construction process. The CMa acts as an advisor to the owner, helping to manage the project and make sure it stays on track.
There are different types of CMa agreements, including B132 “Owner/Architect CM as Advisor”, A132 “Owner/Contractor-CM as Advisor”, and A232 “General Conditions, CM as Advisor”.
In this method, the role of the architect is similar to the traditional delivery method, but with some key differences. For example, the architect works with the CMa during the design and development phase to make a preliminary cost estimate. The architect also submits a design schedule to both the CMa and the owner. If the budget is high, the architect works with the CMa to reduce it, or the owner can approve a change in budget or scope.
The contractor can be chosen through competitive bidding or negotiated with one contractor. Multiple prime contracts can be used, and no GMP and bidding/negotiation are done to award.
In summary, Construction Manager as Advisor (CMa) is a method that allows the owner to closely work with a CMa to manage the construction project, and the architect works with the CMa to make a preliminary cost estimate, and submits a design schedule to both the CMa and the owner.
