Precast Concrete Erection

DM&S has been involved with many structural and architectural precast projects. Often DM&S’ steel erection work complements the installation of precast facades on high-rise structures, providing a seamless project for our clients. DM&S field engineers provide a high level of quality control, ensuring proper layout and alignment. The company employs several field crews that specialize in precast erection and understand the importance attending to the details to make a project successful.

Special Projects

Although Daniel Marr & Son is well known for our expertise in high-profile structural steel erection projects, we also retain several specialized crews that work on smaller projects including miscellaneous metals, tenant fit-outs, renovation to existing structures, and unique rigging jobs. Typically smaller in size, these projects have a high degree of complexity that requires the right team to make it happen. In addition, many of these special projects require additional services such as shoring that goes hand in hand with our work, and with our sister company, Isaac Blair, we can manage and coordinate these activities to ensure a flawless outcome.
