What is an essential characteristic of Design-Build Services?

An essential characteristic of Design-Build Services is the establishment of a single contract with the owner. This approach streamlines the construction process by consolidating the responsibilities for both design and construction under one entity. By having a single point of accountability, communication and coordination between design and construction teams are significantly enhanced, which can lead to more efficient project delivery. This simplifying of contractual relationships reduces the risk of disputes that can arise from having separate contracts for design and construction and allows for a more integrated approach to the overall project management.

The other options might suggest alternative arrangements or characteristics within the construction industry, but they do not encapsulate the primary advantage of the Design-Build model, which is the singular contractual agreement that unifies the design and construction processes. This consolidation is fundamental to achieving the intended efficiencies and streamlined communication within Design-Build services.
