Design-Build’s modern resurgence is a direct response to the the construction industry’s need to overcome the limitations of more segmented approach of Design-Bid-Build.

Today, Design-Build stands at the forefront of modernity, innovation, and efficiency. Celebrated across various sectors, it transforms the typical construction workflow into a flexible, client-focused, and results-driven process.

What Is Design and Build in Construction?

Design-Build is a project delivery method where a single entity - the Design-Build contractor - is responsible for both the design and construction phases.

Unlike traditional models which separate these stages, Design-Build integrates them, enabling the contractor to manage the entire design build construction process, often leading to more efficient outcomes.

Historically, Design-Build isn’t a new concept. Master builders of the past handled both design and construction, but in the 20th century the industry largely shifted to the traditional Design-Bid-Build method, where design and construction duties were distinctly divided.

However, as projects grew in complexity and the demand for faster delivery increased, the industry began reevaluating its methods. This reevaluation spurred what is now seen as a renaissance of the Design-Build method during the late 20th century, aimed at integrating and optimizing construction workflows in response to modern demands.

Today, it’s increasingly adopted as a modern, efficient project delivery method, especially in commercial construction, public infrastructure projects, and industrial sectors.

Recent statistics from The Design-Build Institute of America (DBIA) underscore its impact and growing preference:

• Design-Build is supposed to constitute nearly 47% of U.S. construction spending by 2026.
• Design-Build is also noted for being 6% less costly and 33% faster than traditional methods.
• Nearly 80% of U.S. states now authorize Design-Build for critical public infrastructure projects, emphasizing its increasing adoption and success.

Design and Build Advantages

As we look to the future of the construction industry, it's evident that Design-Build leads the way. Beyond the previously mentioned benefits Design-Build offers additional advantages that further reinforce its value.

Let's narrow down why Design-Build stands out as the preferred choice for construction projects:

• Superior project quality with consistently exceptional results.
• Unified collaboration sparking innovation at every step.
• Accelerated delivery for quicker completion at lower costs.
• Stable costs early on, providing budget clarity from the start.
• Reduced revisions, minimizing changes and disputes.
• Optimized risk management with risks handled by the experts.
• Adaptive design that flexibly responds to evolving needs.
• Clear, direct communication for effective interactions.

Comparison of Project Delivery Methods in Construction

How Does Design and Build Work?

Design-Build approach begins with the initial concept, where the client and the Design-Build team collaboratively define the project scope, objectives, and expectations.

Following the initial agreement, construction kicks off as soon as the first design phase is completed—this overlapping of tasks is referred to as concurrent development. As construction on the early phases begins, the design team continues refining subsequent phases, allowing for continuous progress without delays typically associated with traditional methods.

As construction advances, any necessary adjustments identified are fed back to the design team for immediate action, reducing the likelihood of costly and time-consuming reworks. This dynamic interplay between construction and design teams optimizes problem-solving and decision-making throughout the project.

Design and Build Project Management

Key to this process is design-build construction management, which maintains clear and constant communication among all stakeholders. This continual dialogue guarantees swift and effective project adaptations, making the Design-Build approach particularly suitable for commercial construction, where rapid coordination and response are essential.

Project management software such as Lcmd enables real-time updates, full transparency and effective coordination. This means that all processes in the design-and-build approach can be optimally supported by digital tools.

Examples of Design and Build in Commercial Construction

In commercial construction, Design-Build has proven to be invaluable. It enables large-scale projects to progress with fewer interruptions and greater coherence among the project team.

By having a single entity oversee both design and construction, the approach meets the complex needs of commercial spaces—whether they’re offices, retail complexes, or corporate campuses.

Here are some notable commercial projects that utilized the Design-Build approach:

1. Apple Park (Cupertino, CA, USA) – Apple’s headquarters showcases how Design-Build can manage complex, large-scale corporate facilities with unique architectural demands.
2. Berlin Brandenburg Airport Terminal 2 (Germany) – A key project in Germany that employed Design-Build for its new terminal, demonstrating the method's suitability for commercial infrastructure on a large scale.
3. Siemens Headquarters (Munich, Germany) – The Siemens corporate headquarters used Design-Build to integrate sustainability and energy-efficient technologies seamlessly into a modern office space.
4. The Leadenhall Building (London, UK) – Known as the "Cheesegrater," this skyscraper used Design-Build to accommodate its innovative and challenging design within London's commercial district.
5. Erasmus Medical Center (Rotterdam, Netherlands) – An advanced medical facility where the Design-Build approach was used to ensure integration of modern technology and services, all while maintaining a commercial operation.

Case Study: Design and Build Success in Elbphilharmonie Hamburg (Germany)

The Elbphilharmonie in Hamburg started with a traditional Design-Bid-Build approach, facing delays and a cost overrun from an estimated 77 million euros to 866 million euros. Completion was pushed from 2010 to 2016.

Switching to the Design-Build method in the final stages allowed for better coordination communication, leading to the successful completion of this 120,000-square-meter concert hall with a capacity of 2,100 seats.

The shift demonstrated how Design-Build could rescue complex projects, avoiding further delays and costs.

Conclusion

Design-Build is a proven response to the evolving demands of construction. Its ability to integrate teams, adapt to changes swiftly, and reduce costs makes it nowadays the preferred method. Notably, as projects grow more complex, Design-Build’s collaborative nature is set to drive the industry's future.
