Top 10 Mistakes Owners Make in Design-Bid-Build Projects

Design Bid Build in California is a traditional project delivery method where the owner hires an architect to complete the design, then solicits competitive bids from contractors, and finally selects a general contractor to build the project. It is widely used across the California construction industry for public works projects, commercial buildings, and tenant improvements.

Many owners prefer this method because it provides clear project phases and competitive pricing. However, without proper planning and oversight, Design Bid Build in California can lead to construction cost overruns, change orders, and construction timeline delays. Below are the top mistakes owners make—and how to avoid them.

Top 10 Mistakes Owners Make in Design Bid Build in California

1. Incomplete Construction Documents

What it is:
Starting the construction bidding process with unclear or unfinished architectural plans and project specifications.

Why it happens:
Owners rush through the architectural design phase to save time.

How to avoid it:
Ensure drawings are detailed and coordinated before bidding. Complete documentation reduces risk allocation disputes and minimizes change orders later.

2. Choosing the Lowest Bid Over the Most Qualified Contractor

What it is:
Selecting a contractor solely based on price.

Why it happens:
The competitive bidding structure encourages owners to focus on cost rather than experience.

How to avoid it:
Evaluate general contractor selection based on:

• Experience with similar California projects
  
  

• Knowledge of California building regulations
  
  

• Financial stability
  
  

• References
  
  

The lowest bid often results in quality issues or claims.

3. Poor Scope Definition

What it is:
Unclear project scope or undefined responsibilities in construction contracts.

Why it happens:
Owners assume the architect and contractor will “figure it out.”

How to avoid it:
Define scope clearly in writing, including materials, finishes, systems, and timelines. Clear scope reduces disputes and prevents construction cost overruns.

4. Ignoring Local Regulations and Permitting

What it is:
Underestimating California’s strict permitting and code requirements.

Why it happens:
Owners unfamiliar with California construction laws overlook compliance details.

How to avoid it:
Understand local permitting processes, especially in cities like San Diego, Los Angeles, and San Francisco. Factor in:

• California Building Code
  
  

• Environmental regulations
  
  

• Accessibility standards
  
  

Regulatory delays can stall projects for months.

5. Underestimating Change Orders

What it is:
Failing to plan for modifications during construction.

Why it happens:
Owners assume the original plans will remain unchanged.

How to avoid it:
Budget contingency funds (5–10%). Many change orders stem from incomplete documents or evolving owner preferences.

6. Weak Construction Management

What it is:
Lack of structured project management oversight.

Why it happens:
Owners assume the contractor handles everything.

How to avoid it:
Implement strong project management practices:

• Regular progress meetings
  
  

• Cost tracking
  
  

• Schedule monitoring
  
  

• Risk assessment
  
  

Without oversight, delays and disputes escalate quickly.

7. Lack of Communication Between Architect and Contractor

What it is:
Minimal collaboration after bidding.

Why it happens:
In Design Bid Build in California, the architect and contractor operate under separate contracts.

How to avoid it:
Encourage coordination meetings to resolve conflicts early. Clear communication prevents errors and rework.

8. Unrealistic Budget Expectations

What it is:
Expecting 2020 pricing in today’s California construction market.

Why it happens:
Material costs, labor shortages, and supply chain fluctuations are underestimated.

How to avoid it:
Request updated cost estimates during the design phase. Compare market conditions in the California construction industry before finalizing budgets.

9. Skipping Pre-Construction Planning

What it is:
Failing to conduct constructability reviews before bidding.

Why it happens:
Owners focus only on design aesthetics.

How to avoid it:
Involve professionals early to review:

• Buildability
  
  

• Scheduling feasibility
  
  

• Site logistics
  
  

Pre-construction planning reduces construction timeline delays significantly.

10. Not Hiring Professional Construction Management Services

What it is:
Managing a complex project without expert guidance.

Why it happens:
Owners try to reduce upfront costs.

How to avoid it:
Professional oversight improves coordination, cost control, and compliance. In high-regulation states like California, expert management is critical for success.
