With experience working on a vast array of project types and sizes, Mainelli Mechanical’s VDC Team has the tools and capabilities to assist with all of your project’s modeling needs. Our Team utilizes the latest in construction modeling technology to preform everything from leading trade coordination to fabrication and installation of mechanical and plumbing systems. Our VDC Team strives to make our field installation as smooth as possible by writing any necessary RFIs, coordinating the systems in to place and providing precise installation and fabrication drawings before our field staff is even on site. This allows our field crews to go in with a plan and make your project more efficient.
