Systems: Plumbing, Hydronic Piping, Heating, Ventilation, Air Conditioning, Insulation, Controls
Size: 7 story office building with an attached parking garage
Note: We had to tie into existing city utilities in order to bring the building online. 3D coordination used throughout the project both in the field and in the fabrication process.
Systems: Plumbing, Hydronic Piping, Heating, Ventilation, Air Conditioning, Insulation, Controls
Size: 250,000 sq ft building with 1 floor of retail and 9 floors of office space.
Systems: Size: 7 story office building with an attached parking garage
Note: HVAC systems utilizes a custom desiccant air handling unit to serve over 900 chilled beams throughout. 3D coordination used throughout the project both in the field and in the fabrication process.
Systems: Plumbing, Hydronic Piping, Heating, Ventilation, Air Conditioning, Insulation, Controls

Systems: Plumbing, Hydronic Piping, Heating, Ventilation, Air Conditioning, Medical Gas, Insulation, Controls
Size: 9 stories including 7 floors of patient care
Note: Extensive 3D coordination and pre-construction work went into this project. Mainelli has maintained a full time staff at UNMC/NeMed campus since 2005 to address day to day mechanical system needs.
Systems: Plumbing, Hydronic Piping, Heating, Ventilation, Air Conditioning, Fuel Oil, Insulation, Controls
Size: 4,000,000 sq ft of data centers for one client
Note: Project consisted of a green field build out with multiple buildings to serve the needs of the owners ever changing needs. To expedite schedule, a second fabrication location was brought on-line working closely with our 3D design team to coordinate materials before the schedule required installation. Throughout the project, high level quality control measures and commissioning.
