Providing a Full Range of Construction Services
Lead. Plan. Execute.


We minimize risk by prioritizing client goals and fostering collaboration. Successful design-build projects require transparent communication, accountability, collaboration and the right team of design and construction professionals. We draw from our network of creative designers to assemble a high performing professional team to meet the vision and technical requirements of each unique project.

Our leadership during design ensures schedules are maintained, budgets are closely monitored and the constructability is on track. Our experience has shown that a well-led design-build project results in faster delivery, high quality and effective cost management. More importantly, we ensure our clients are always informed and in control. Our number one priority is that the client’s vision for the project is achieved.

"The team quickly helped us to focus our project to best align with our mission and our vision for the Cathedral Parish and Harrisburg Catholic Elementary School. Each step of the way, they guided us not only with expertise but with integrity ensuring that our dreams would come to fruition. While exhibiting professionalism to the highest degree, I came to see quickly that the JEM approach is a personal approach. This is the secret of their success. JEM has become part of the Cathedral and Harrisburg Catholic Elementary School family."
