MDS works with owners and architects, federal, state and municipal agencies to create and build libraries, museums, community centers, transportation and religious facilities to serve the public. We understand that public or private projects must account for and demonstrate value for money in capital cost and operation. We strive to create resilient and sustainable systems to last and serve for many years in the future. At the same time, we believe it is our responsibility to preserve the past. Our historic preservation projects showcase modern and robust mechanical systems that integrate with the existing structure while maintaining their historic fabric.
