The foundation of our success.

Hathaway Dinwiddie’s leadership in the construction industry is built upon the professionalism and dedication of our employees, combined with the integrity of our client relationships.  This foundation has fostered a culture that incorporates client focus, innovative thinking, proactivity and teamwork to deliver superior services.  As a result of our highly collaborative approach, we often enjoy repeated client work engagements.

General Construction

For Hathaway Dinwiddie, no job is ever too large or too small.  We provide general contracting and complete project planning and management services in California’s most dynamic markets. For over a century, we’ve helped the nation’s premier companies and institutions develop landmark structures and quality interior spaces. With a tradition of innovation and superior project delivery, we are a leader in the construction of large-scale, commercial and institutional projects, tenant improvements and historic renovations. We specialize in a variety of project delivery methods, from the traditional plans and specs approach to full service program management and design-build. Our vast project portfolio covers everything from 1,000sqft interiors and renovations to 1,000,000sqft+ ground-up and core-shell buildouts.


Hathaway Dinwiddie provides advanced preconstruction services utilizing the most progressive techniques and technologies available. Our team is composed of individuals who possess the experience, techniques and capabilities necessary to successfully deliver projects to the total satisfaction of our clients. We establish, develop and maintain relationships with all members of the project team, and create an environment based upon open communication and mutual trust.  In doing so, we quickly gain a thorough understanding of project goals, interrelationships, responsibilities, schedules, budgets, protocols and accountabilities in order to ensure predictable and effective project delivery.


Hathaway Dinwiddie believes that design-build success begins with mutual respect for all team members.  We foster a work environment that simplifies both free-form and structured information exchange between all participants.  Hathaway Dinwiddie design-build professionals are experts in their field, who partner with owners  and manage all aspects of the project, from architecture and engineering to the design and installation of the trades. Our design-build engagements  cover entire construction projects or specialty components, such as  trade management, MEP, drywall, grade shoring systems, curtainwall, exterior framing, fireplaces, pool design and more.

Construction Management

Hathaway Dinwiddie project managers see the big picture and the minute details.  We help clarify overall goals before design time is invested, and stay highly engaged through project completion. We recommend the best delivery process and then coordinate and track all resources to achieve scheduling milestones. Experts in planning and time management, we build project plans that incorporate conceptual and detailed estimating, budget tracking, sub-contractor identification and construction scheduling. Every component of our management process is built around project delivery that is safe, timely, cost-efficient and of premium quality.

Interiors and Special Projects

While primarily known for larger projects throughout California, Hathaway Dinwiddie is also one of the most active interior and renovation contractors in the state.  On average, we complete over one hundred million dollars’ worth of interior construction per year.  Regardless of project size, we approach every one with the same level of detail and collaboration.  Our interiors group is highly specialized and understands the challenges inherent in this type of construction. Occupied buildings, tight budgets, fast track schedules and quality workmanship are our strengths.  Projects range from small remodel work to large buildouts in both core-shell space and occupied buildings.
