TMI's Plan & Spec projects include:


Swedish Covenant Hospital, Chicago
As this North Side hospital expands with a three-story, 11,500 square foot addition and accompanying 2,200 square foot renovation at its Galter Medical Pavilion, TMI is hard at work providing both HVAC systems and medical gas systems. The first floor of the addition will house Interventional Radiology and the second floor is dedicated to Invasive Cardiology and Cardiac Cath Labs. The third floor is an enclosed mechanical penthouse into which TMI is installing a new 30,000 cfm air-handling unit. Additional equipment installed by TMI includes a new 250-ton chiller and 5,000-gallon underground fuel oil tank. As with any hospital project, TMI's experts are careful to keep patients as undisrupted as possible. This new addition marks the 14th project TMI has performed for this growing hospital - a testament to a strong working relationship and to TMI's special abilities to perform complex mechanical installations in a busy and sensitive environment.


Little Village High School, Chicago
For this Southwest Side Chicago community, which didn't have an existing neighborhood high school, TMI is part of a fast-track construction team building a two-story masonry and steel structure including a swimming pool, auditorium, gymnasiums, full-service kitchen, plus music, science and other special classrooms. The 225,000 square foot school construction began in winter 2003 and is scheduled for completion by June 2005. The installation of the mechanical systems by TMI is particularly aggressive as the permanent heating system will be in use during the remainder of the project construction. TMI's work includes 17 major fan systems and equipment for heating and cooling, insulation of equipment and pipe, plus computerized temperature control systems.


Northeastern Illinois University, Chicago
In January 2004, TMI began the complete HVAC renovation of NEIU's 1960s-era, six- floor Building C. TMI conducted the demolition and replaced the outdated systems, including all piping and insulation. The project required extra coordination with other trades and line stops on existing piping. Rather than shut down the HVAC systems to the entire campus during renovation, TMI welded line stops to shut off the 300 degree, 300-psi hot water while construction was underway. A high-profile project, the completed Building C will house NEIU's entire administrative and executive branch of university, including the university president.


SBC, Northbrook, Ill.
TMI has handled several projects over the years for SBC, including the removal and replacement of two 500-ton chillers (main and backup) and related cooling tower systems at a critical SBC facility in Northbrook. To ensure 100% cooling redundancy at all times and to make certain this strategic SBC building stayed 100% functional during construction, TMI temporarily used truck-mounted 500-ton chillers and generators as backup. The end benefit of renovation to SBC is the modernization of its equipment and increased energy efficiency. Because of TMI's demonstrated ability to operate in and around SBC'c highly sensitive switching equipment, TMI is one of a select few contractors allowed to work in these facilities.


900-910 North Lake Shore Drive, Chicago
While black steel was a common construction material for pipe risers in the middle of last century, many smart building owners and managers, like those at 900-910 North Lake Shore Drive, are recognizing the need to preventively replace their pipe risers with copper pipe or other less corrosive material. For these twin, 30-story condos built in the late 1950s by influential architect Mies van der Rohe, TMI is conducting a proactive, multiphase, three-year replacement of all the heating/cooling pipe risers, 12 per building, that feed fan coil units in each condo unit. In all, the project will encompass the replacement of more than 10,000 feet of pipe. Because the condos are occupied, TMI is using copper, which makes for a cleaner installation with fewer fumes as it is soldered instead of welded. TMI has developed specially trained crews that are sensitive to the security and housekeeping concerns of tenants present in their condominiums while the work is in progress. TMI is also conducting the work during the milder spring and fall seasons so the residents can better accommodate the temporary HVAC shut offs. TMI, as a niche specialty, is currently performing phased multiyear replacement work at a number of other high rises throughout the city, including another Mies van der Rohe structure at 330-340 West Diversey. Many of Chicago's 30- to 50-year-old condominium buildings need such work completed before costly pipe failures occur.


Glenbrook North High School, Northbrook, Ill.
With the addition of a second pool, Glenbrook North High School now boasts one of the premier swimming facilities in the region. During the addition, TMI made certain the existing pool remained operational during construction, despite some shared elements between the old and new pool systems. TMI installed a Dry-o-tron HVAC/dehumidification system, which works as a heating, cooling and dehumidification system all in one. Strategic phasing was particularly key in this project. The second pool was added next to an existing outer wall of the original pool. Once the second pool was complete, the wall between them was removed and the original pool facility renovated. Now there are two pools in one large open space, but they are governed by two different HVAC/dehumidification systems.
