Our Purpose: 
To discover and deliver value better than anyone in any industry.

Herrero Builders is a San Francisco-based commercial general contractor, proudly serving Northern California since 1955. We are recognized leaders in Integrated Project Delivery (IPD) and Lean Construction.
  
Our work spans new construction, seismic upgrades, and tenant improvements across a diverse range of markets, including healthcare, education, commercial, retail, historic, and hospitality.
  
Through the Herrero VIP™, we take a value‑driven approach to project delivery. We begin by discovering what matters most to all project stakeholders, then align everyone around those shared values. From there, we implement the processes, systems, metrics and culture required to consistently deliver on values.
  
Herrero has earned a strong reputation among our customers and industry peers for integrity, innovation, and service. More than 20 years ago, we pioneered a groundbreaking journey by adopting Lean construction principles, Integrated Project Delivery (IPD) methodologies, and Virtual Design and Construction (VDC) technology. These innovations have transformed how we build and continue to elevate our ability to deliver meaningful, lasting value on every project.

VALUES / CORE IDEOLOGY

Our values and core purpose guide every project, every hire, and every decision. We obsess over discovering what’s most valued and aligning everyone to deliver it. Revealing what matters most is where we excel.

Finding
what’s valued.

We take the time to understand what customers truly value. Every project begins with the Herrero VIP™, a disciplined approach that makes value visible, measurable, and actionable, identifying what matters most to all stakeholders, we drive better alignment and stronger outcomes.

Listen. Align. Deliver.

We have a process for that.

Our processes drive reliable results. We approach every project with holistic, systems‑based thinking, planning intentionally, capturing meaningful data, and continuously improving. These systems enable us to deliver consistent, predictable outcomes for our clients.

Plan. Do. Check. Act.

Count on me.

We stand behind our commitments and deliver on our word. If circumstances affect that promise, we take full responsibility and accountability to make it right. Trust is key to success.

Promise. Deliver. Trust.

Always learning. Always teaching.

We are a learning organization that believes in teaching as much as doing. By sharing knowledge across teams, clients, academia, and our industry, we help build a better future for everyone involved.

Learn. Share. Improve.

Relationships matter. Deeply.

Relationships matter most to us. We show up to help, to serve, and to build lasting connections with our customers, trade partners, and team. Our success is rooted in a deep investment in people.

Connect. Respect. Collaborate.

Herrero VIP™.

The magic is in our ability to make hidden values visible.

A Lean Approach: Understanding what you want and give it to you

Herrero Project VIP™, is our leadership process for discovering collective value, defining what success truly means, and delivering that value exceptionally well throughout the project’s entire lifecycle.

 Our strength lies in our ability to make hidden values visible. We align values, behaviors, and processes, while intentionally blurring the traditional boundaries between owners, designers, and builders. This Lean, integrated approach creates shared ownership, stronger collaboration, and better outcomes for customers.

Safety

We live by our core values and nowhere is that more true than in our Safety practices. We understand that projects are built, not by processes or procedures, but by people. We have been entrusted with the precious responsibility of keeping our people safe, and in turn, we provide our people with the systems and the autonomy that are essential for job-site and workplace Safety.

Herrero voluntarily exceeds state and federal regulatory Safety standards. Aligned with Lean construction practices, our Safety program uses a systematic approach with a focus on continuous improvement. The key elements of this program are: management leadership in safety, worker participation, consistent implementation, regular evaluation, and both corrective and preventive action planning.

Safety Awards

Herrero Builders has received the President’s Safety Award from the Construction Employers Association (CEA) for the last four out of five years and we have also been a recipient of the CEA’s Safety Excellence Award for the past seven years.
