Final answer:
The major disadvantage of design-build projects is that early poor design decisions can lock the project into ineffective parameters, potentially leading to failure. It also discourages new ideas due to the lack of flexibility during construction and can result in a large bureaucracy.
Step-by-step explanation:
A major disadvantage of the design-build project delivery structure is that poor design decisions made early in the process can lead to a design that fails to meet the customer's needs. This can be particularly problematic because the design-build approach encourages early finalization of design concepts, which can lock the project into certain parameters without adequate flexibility for changes as the project develops. The design-build approach integrates design and construction stages, which can be beneficial in terms of collaboration and efficiency. However, the downside of this integration is that if the initial design is flawed, the subsequent construction is also likely to be compromised, leading to cost overruns, satisfaction issues, and potentially the failure of the project.
Another issue with the design-build structure is that it may discourage new ideas and flexibility on a day-to-day basis. With a focus on adhering to an established plan, there may be less incentive and fewer opportunities for team members to propose improvements or innovative solutions during the construction phase. Additionally, this structure can lead to a large bureaucracy, making it challenging to make timely decisions.
