Pros, Cons and Best Practices of the Design-Bid-Build Construction Methodology
The design-bid-build methodology represents the most traditional project delivery approach leveraged across commercial building sectors and municipal infrastructure upgrades alike at nearly 60% market share. It's praised by some and criticized by others compared to alternative methods like CM and design-build.
But what's the real story behind this blog? Like many methods, there are positives and negatives. Here, we'll explore the advantages, drawbacks, when it fits best, and smart advice for using design-bid-build effectively.
In this blog, we will discuss important topics about the pros, cons and best practices of the design-bid-build construction methodology:

The Advantages of Design-Bid-Build Project Delivery
These are some of the primary advantages of the tried-and-true DBB system:
- Enhanced Quality Control
The structured design-bid-build phases foster strong quality assurance through expert task specialization. Architects and engineers concentrate exclusively on fully engineered drawings and BIM models before involving bidding general contractors. This checks and balances technique reduces missteps. DBB phases help ensure top-notch quality by focusing on expert drawings and models before involving contractors, reducing errors. - Competitive Transparent Bidding
Public DBB project specifications allow wide general contractor participation in RFQ processes. Broad competition pools for subcontracts drive bidding efficiency revealing current market pricing. Winners earn contracts without subjective preferential awarding muddying markets. Public DBB projects allow many contractors to bid, promoting fair competition and revealing current market prices. - Firm Fixed Price Contracts
Lump sum contractor proposals lock in set pricing after bidding concludes without creeping adjustments for materials or skilled labor inflation over multi-year projects. Owners maximize budget predictability knowing definitive construction costs before signing agreements. DBB contracts lock in prices, offering budget predictability without surprises due to material or labor cost fluctuations. - Greater Individual Owner Control
Because DBB keeps design and planning separate from build procurement, clients retain greater direct influence over specifications before securing a general contractor. Clients retain control over specifications before choosing a contractor, preventing overrides of their preferences. - Clearly Defined Participant Roles
Participant responsibilities stay well-defined over project lifecycles. Architects design. Engineers specify. General contractors estimate and build. Subcontractors supply specialized trades expertise. Owners monitor budgets. This assembly line approach prevents scope overlap inefficiencies.
While certainly beneficial across many public and private builds, DBB has its limitations...
The Disadvantages of Design-Bid-Build You Cannot Ignore
These are some of the drawbacks that can affect design-bid-build efficiency:
- Linear Phasing Hinders Adaptability
DBB's rigidly segmented phases limit collaboration between architects, contractors, and tradespeople until after the contract is signed. This restriction prevents early valuable input from builders, which could optimize functionality, maintenance, and budgeting, reducing costs associated with changes made later in the process. - Minimal Design Phase Collaboration
Builders typically offer advice during the bidding phase, missing out on opportunities to improve value through ongoing collaboration that is characteristic of more integrated construction methods.
- Higher Potential for Adversarial Contracts
DBB's sequential structure often limits collaboration once pricing becomes fixed. This can lead to an 'us vs. them' mentality between owners and builders. Owners might get frustrated with change orders, while builders may feel micromanaged while executing the signed scopes of work. - Unclear Design Details Generate Avoidable Changes
Incomplete or unclear drawings may lead contractors to propose changes to recoup costs for unaccounted work. This can create disputes between owners, who might feel surprised by extra charges, and contractors, who seek compensation for unforeseen adjustments. - Concentrated Financial Risks
Owners might face amplified financial risks due to the need to pay designers and contractors separately. Additionally, they bear the burden of price overruns caused by undocumented changes. However, early control over the project's direction might offer some offset to these risks.
It's important to recognize that no single construction approach fits all projects perfectly. Understanding these drawbacks helps in considering the nuances and determining when and how to appropriately use the DBB method for optimal project outcomes.
Factors to Consider When Choosing Design-Bid-Build Project Delivery
Selecting the right approach for construction projects is pivotal, and Design-Bid-Build (DBB) has its unique strengths. Evaluating certain factors helps discern the situations where DBB becomes a more suitable choice:
Optimal for Simpler Projects: DBB method fits well with straightforward endeavors, such as basic office renovations or constructing simple steel warehouses. Its linear structure is ideal for managing such uncomplicated tasks efficiently.
Early Clarity in Project Details: DBB performs exceptionally when project specifics are well-defined and complete from the outset. Having comprehensive details minimizes uncertainties, ensuring a smoother project flow during construction.
Focus on Budget Management: For owners more concerned about maintaining budget control than expediting project timelines, DBB offers advantages. Its transparent bidding processes empower owners to control costs using competitive market pricing as the primary selection criterion.
Dealing with Tight Budgets: In scenarios where budgets are stringent and inflexible, DBB proves beneficial. Even though DBB procedures may take longer, the method's defined scopes provide crucial cost predictability essential for projects with limited financial flexibility.
These circumstances highlight how the DBB project structure aligns better with effectively managing risks, maintaining expense controls, and delivering predefined designs within set budget constraints.
Tips for Effective Design-Bid-Build Implementation
To ensure successful execution of design-bid-build (DBB) construction, it's crucial to adapt strategies to fit specific project constraints. Here are some recommendations:
- Prioritize Comprehensive Design
Invest more time in thorough planning, including detailed specifications and precise surveys. This upfront investment helps avoid costly changes later in the project that could strain the budget. - Assess Builder Qualifications Thoroughly
Look beyond bid costs and examine a contractor's technical abilities, previous project performance, and their ability to collaborate effectively. Choose partners who align with your project goals. - Demand Contractor Guarantees
Ensure that general contractors provide financial surety bonds to cover potential replacement costs if they fail to deliver as agreed upon. These bonds protect against overlooked scope details in low bids. - Structure Service Contracts Wisely
Include clauses in contracts that enforce quality standards through penalties or milestone-based payments. Aim for fairness without unfairly burdening any party involved.
The widespread utilization of the design-bid-build model, coupled with tailored planning and communication, has consistently delivered successful outcomes in various commercial and public construction projects.
