Construction Leadership Since 1919

Experienced Professionals

Strong leadership serves as a building block for all our operations. At J. Vinton Schafer, our staff is our greatest asset. We know that our success and, ultimately, the success of your project, relies on our employees. We understand that you place your trust in us to build your project because of our staff’s qualifications, experience, and knowledge in delivering construction solutions. Each of our project managers and superintendents are required to have 30-hour OSHA training every five years.

Safety: First. Last. Always!

We are committed to construction safety. It is a commitment and the first core value that we have built into our culture. This commitment begins with the philosophy of “Safety First” in everything we do. We mean it when we say, “Safety: First. Last. Always!”. We are dedicated to centering each construction phase on resident, staff, visitor, and employee safety. Safety guides our processes, planning, and approach to each project.

At J. Vinton Schafer, our standards are guided by our core values that define our commitment to providing a safe work environment supported by policies that meet or exceed federal, state, and local laws. We are constantly thinking about ways to work safely. We define success in safety when every employee on every project site can return home to their families safely.

Our safety program is integrated into our culture and on our job sites through training, education, and going beyond industry standards. We make an industry-wide effort to train our colleagues to prevent any worker in the industry from suffering an injury. We provide on-site training for various hazards that workers may encounter, including job safety analysis, OSHA 10- and 30-hour training for construction and general industry (500 & 501), and even confined space, excavation, fall protection, and equipment operating training. We are vigilant in inviting OSHA consultants and private safety consultants to survey our safety program and provide feedback to keep every single site an injury-free zone.

Our construction team personnel are certified in First Aid, CPR, AED, and OSHA 10-hour at a minimum. Each year, our team members complete additional safety training to enhance their knowledge of project-specific challenges. We also have a Text Observation Process (TOP) program used for superintendents and project managers to report Safety Observations easily and Near Misses and corrective actions in real-time from an app on their phones. Safety Talks are presented every week and shared with subcontractors. We also have a subcontractor prequalification process to review subcontractors’ safety process and financials. We believe in the importance of regular safety inspections and weekly job site inspections. Year after year, we can maintain our EMR rating well below the industry average of 1.00.

Our most important asset is our people. We consider every individual in our offices and on a job site our company’s responsibility. Employee safety not only affects what happens on the job, it also affects the personal lives of our workers and the people they love.

The Markets We Serve

From healthcare to senior living to student housing, we have the resources to construct your most demanding projects.

Civic / Government

We are committed to advancing how construction supports and fosters civic life. We build safe and welcoming buildings where citizens can grow and learn, and where they can strengthen their community ties. Our civic portfolio includes firehouses, libraries, and federal office fit outs that shape the built environment and create lasting value for the communities they serve.

We understand the unique approach that corporate and specialty facilities require from multi-story corporate offices to mission-critical data centers. We work closely with each client to establish a vision reflecting the company’s mission, culture, and current and future needs. This approach supports changing technologies, provides flexibility for growth, and enhances a corporate sense of community to attract and retain the best and brightest employees. With a hands-on approach to construction management and single-source solutions, we provide clients with confidence that their facilities will be completed on time, on budget, and to their specifications.

PK-12 Education

Every school building program sets out to achieve a mission. This mission aims to establish a foundation that enables students to gain the skills necessary to become productive and successful adults. Likewise, we realize that a winning project begins with a team approach. From planning through occupancy, we will work with you and your design professionals to refine and monitor the scope, cost, schedule, and quality of your project, which will serve the needs of your students for decades to come.

Higher Education

Just as any building needs a strong foundation, our students need a strong foundation as they advance their education. We are continually inspired by opportunities to build physical environments that enhance academic communities across the full spectrum of programs, organizational structures, and institutional missions. We are dedicated to creating dynamic, learning environments that provide opportunities for students to collaborate and inspire intellectual an physical activity and social connections. We keep current with educational trends and supplement our project experience with independent research initiatives and post-occupancy evaluations. In addition to building instructional and research spaces that are responsive and adaptable to the program needs, we also place a great deal of attention on “in-between” spaces to foster social interaction and the cultural attributes of the academic community. We realize the value of a close working relationship as we collaborate with you and the design professionals to refine and monitor program scope, cost, schedule, and quality. We construct facilities that serve the needs of your students for decades to come.

Pride in our Community

Dedicated to giving back and supporting the communities where we work, live, and build, we are committed to providing financial support, giving our time, and bringing smiles to those in need and to our community heroes.
