Design-build is a simple construction delivery method, in which the design and construction of your HVAC system is provided by a single entity. Design-build provides one point of contact and minimizes owners risk and reduces project delivery time by overlapping design and construction phases.

Why design-build?

 By project delivery, we mean a comprehensive process including planning, design, and construction to execute and complete a building or other type of project. 


Within the construction industry, there are multiple project delivery systems (design-bid-build, multiple-prime contractors, construction management at risk, and design-build) owners choose from to complete their project - design-build is one of those options.

It is not uncommon under traditional forms of project delivery that the information provided is not sufficient to bid and build the project. When this happens, disputes, claims and change orders are often the result, with the owner caught in the middle of the finger-pointing between the designer and the contractor.

History of design-build

Design-build is often compared to the concept of the master builder which existed in ancient times and into the Renaissance. Many of the great wonders of the world were created using this methodology. The master builder was not a contractor, an architect or an engineer. The master builder was the embodiment of all three disciplines. The master builder concept depicts the earliest model for delivering design and construction as an integrated service.

design-build history

Toward the end of the Renaissance, design and construction began to separate. Individuals began to identify themselves as either designers or construction tradesmen. Guilds were formed. As the Industrial Age unfolded, specialization affected all aspects of western culture. Professional associations and societies came into being, further defining the separation between architects, engineers and contractors. Specialization continued to support more segregated project delivery models throughout the nineteenth and early twentieth centuries. 

Over the years, the design and construction industry degenerated from a culture of cooperation, teamwork, trust and mutual respect to one of fragmentation and inefficiency. There are many historical reasons this happened, but in the past few decades, many organizations are making efforts to restore the design and construction industry to its collaborative roots. Design-build has thrived because owners see the need for change in the way projects are delivered. 

Design-build is intended to be a highly collaborative, fully integrated process that is built on trust, mutual respect, teamwork, innovation, create problem solving. Design-build unleashes the power of team to deliver projects faster, better and for optimum cost - best value for the money, time and effort invested. Owners find that when design-build is done right, their level of engagement with the entire team is more meaningful than is experienced with other delivery methods.

Across the country and around the world, design-build successfully delivers both horizontal and vertical construction projects with superior results, no matter the project type. 

Advantages of design-build construction

  • Saves time - numerous studies have shown projects can finish 12% - 33% faster than projects where the contractor and designer are under separate contracts. 

  • Value engineering - brings all members of the contract team together to address issues of cost, schedule and constructibility.

  • Budget - instead of waiting until the project is underway, issues are addressed at the onset of the project. United Team Mechanical can provide best-value solutions for various HVAC elements before the design is complete. Some studies show a savings of up to 6%.

  • Owner friendly - reduces owners risk for design errors, mounding change orders and additional headache. Design-build keeps the owners and general contractors from being placed directly between the architect/engineer and the contractor. Furthermore, this relives the owner of major legal and managerial responsibilities.
