This method requires clients to mediate between the architect and the contractor, often leading to delays and added costs due to miscommunication or design discrepancies. Clients first work with an architect to develop the design, and then solicit bids from contractors for the construction phase. In contrast, the design-bid-build method involves separate contracts for design and construction services.
This integrated approach offers clients the ease of working with one team, ultimately reducing the likelihood of miscommunication and disputes between the architect and the contractor. As the design-builder, we are responsible for both the design and construction phases, streamlining the entire process. design-bid-build?ĭesign-build is a construction method that unifies design and construction services under one contract. Since the owner supervises both parties, they are also responsible for the problems associated with each.What is design-build vs. A lack of input from all stakeholders early on in the process can highlight problems much further down the road and lead to more time crunches and expensive redesigns and rebids.Ĭhange orders, busted timelines all fall on the owner’s shoulders as they develop two separate contracts–one with the designer and the other with the contractor. Keeping construction professionals divorced from the design process might encourage creativity but sometimes challenging designs can’t be easily translated into finished projects. They include: Possibility of Longer Timelinesīecause the sequential DBB method waits for each party to completely finish its tasks before moving on to the next one, the project might have a greater chance of being delayed. Design-build compresses the project lifecycle and time by encouraging overlap between the design and construction phases: construction can begin even when the design team is ironing out certain aspects of the design.ĭespite design-build’s growing popularity, the traditional design-bid-build approach continues to occupy key segments of the construction industry.Ĭons of Design-Bid-Build The DBB process has its fair share of challenges. The traditional DBB method has worked well for years but is seeing competition from a more nimble approach, the design-build project delivery method. The construction industry too has dozens upon dozens of subspecialties, each of whom like to stay in their lane, a process that DBB accommodates.
The DBB method insists on transparency of costs upfront–which is not to say that ballooning change orders will not add to the bottom line later–and has made it a favorite in public contracts that are subject to rigorous oversight. Its advantages and disadvantages are also well understood. Firmly established in construction, and the go-to approach in the industry for decades, if not centuries, DBB, also known as design-tender, is clearly defined.
