To form a team dedicated to providing exceptional customer service. We aim to provide a professional approach to constructing exceptional quality projects which meet established budgeting and scheduling goals.

Our employees are our most valuable asset and we will continue to invest in them. We strive to provide competitive wages, quality medical and dental plans, pension and profit sharing and state-of-the-art technology systems and training. We want each employee to be proud to be a member of the Devcon Team.


As a respected construction firm, Devcon has partnered with many distinguished developers, owners, architects and tenants. We bring innovative construction expertise built on 45 years of successful business practices and projects. It is our goal to partner with accomplished, innovative consultants and experienced, responsive trade partners in order to maintain excellence throughout our projects. As the Bay Area leader in design/build, our services support all integrated aspects of design and construction, eliminating cost overruns and schedule delays without compromising design intent. We are uniquely experienced in many markets such as corporate campuses, educational institutions, housing, civic and sports centers. This diverse experience empowers Devcon to be a trusted partner in all aspects of shell and tenant improvement construction. Our construction teams in the field are comprised of proven, dedicated employees whose knowledge is informed by both the long-time construction experience here at Devcon and additional comprehensive, ongoing training in the areas of safety, technology, building systems, code compliance, cost engineering and sustainability. At Devcon, we consistently exceed expectations by delivering completed projects that respond to client requirements, adapting to changing work environments, incorporating sustainable materials and technologies, and providing quality structures that perform long after the construction is completed.


Building Services:

  • Design-Build - A unique method of project delivery in which the architect and contractor act as a design-build team and are under the same single contract to the client. This approach creates a unified work flow from conceptual design to construction completion.

  • General Contracting - We facilitate the overall coordination and oversight of our projects by orchestrating the construction site, the management of subcontractors and trades, and the communication between all involved disciplines and parties throughout the entire project timeline.

  • BIM - Building Information Modeling refers to the process by which designers create a 3D digital representation of both physical and functional characteristics in a space using various tools and technologies. Devcon generally uses BIM to coordinate between multiple building disciplines.

  • Estimating - Ultimately, the estimating process allows Devcon to establish a Guaranteed Maximum Price (GMP) that we will then use to create a detailed cash flow forecast and construction schedule.

  • Infrastructure - Our construction teams in the field are comprised of proven, dedicated, responsive employees whose knowledge represents not only long-time service here at Devcon, but comprehensive, ongoing training in the areas of safety, technology, building systems and code compliance.

  • Pre-construction - In the early planning stages of a project, our design and construction departments will work with the client to develop drawings, budgets, and schedules while providing insight into the contributing variables such as materials and construction methods.

  • Project Closeout - This process occurs during the last stage in the construction project lifecycle. During this process, the contractor must demonstrate that the project meets its completion criteria and that all project documentation is approved and tracked. Project closeout also includes the final closure of all contracts and financial packages.

  • Tenant Improvement - These improvements are required when an owner or developer agrees to provide interior improvements to their structure as a lease agreement with the tenant. These customized improvements are often very specific to the tenants needs. 


Our employees perform, our processes perform, and our buildings perform. The challenge in today’s construction industry is to be able to maintain and optimize strong performance levels through all phases of design and construction. We invest in innovative technology to support the management and coordination processes throughout each project. The contemporary software and organizational systems allows for the development of collaborative construction tools that include Building Information Modeling (BIM) and project review software Navisworks. Integrated processes and responsive solutions ensure that unexpected in-field coordination and schedule delays are avoided. These systems continue to perform for our clients, providing them with programs that monitor building energy consumption and operational costs at project completion, ensuring that buildings perform at optimum levels throughout their life cycle.



Our internal design team offers limitless resources and experience for developers, owners and architectural firms. Having an in-house design team allows us to deliver a synchronized communication style with consultants and clients alike throughout all phases of design and construction in an otherwise somewhat fragmented process. Revit and advanced rendering software have provided a collaborative platform for communicating knowledgeably and efficiently with our architectural consultant and trade partners through 3-dimensional visualizations and graphic communication. By partnering internally, we also become a resource for our own construction teams and our construction teams become a resource for our design team, each providing insight into questions concerning construction details and specifications. We take the concept of team very seriously at Devcon, by encouraging strong performance by both our design and construction departments, whether they are supporting a complete design-build model or an integrated project delivery method.



Education and integration are key to any design and construction firm. They are the two most important components of innovative sustainable building construction. Our process and practices are derived from harnessing the power of information from experienced consultants and providing the education to our own internal teams on innovational developments and requirements that are continually shaping the sustainable construction industry. We pride ourselves on the completion of over 100 LEED projects and having over 50 LEED professionals within our design and construction groups. At Devcon, we continue to incorporate and seek alternative sustainable building processes and practices, ensuring that our buildings not only meet our client’s current needs but the needs of the future.
