Which contract type provides a single point responsibility for project design?

The correct answer is the contract type that provides a single point of responsibility for project design, which is known as Design and Build (DAEDS). In a Design and Build contract, the contractor is responsible for both the design and the construction of the project, thereby creating a clear line of accountability. This arrangement simplifies communication and coordination, as the same entity handles both phases of the project.

This single point of responsibility can significantly enhance efficiency and reduce the likelihood of disputes, as the contractor’s design choices directly impact construction, and they are tasked with managing both aspects cohesively. This integrated approach can lead to faster project delivery and an overall more streamlined process, which is often advantageous in complex projects where design and execution are closely linked.

Other contract types mentioned do not offer the same level of coordination and accountability. For instance, fixed-price contracts may focus predominantly on the cost and completion timeline but do not inherently ensure that the design and construction responsibilities are unified under one party. Similarly, unit cost contracts allow for payment based on the quantity of work performed but can complicate the responsibility for design decisions. DADS, which refers to a different contractual framework, might not provide the same clarity and efficiency as DAEDS.
