The Illinois Supreme Court building was constructed in 1906. The Illinois Capital Development Board procured the nearly $16 million renovation and restoration of the courthouse. In May 2013 Korte & Luitjohan Contractors, Inc., was selected as the coordinating contractor for the project. K&L's contract covered $7.7 million of the total renovation cost. Del Scott served as K&L's Project Manager and coordinated all work of the other prime contractors and over twenty subcontractors. Under Mr. Scott's supervision, K&L completed the renovation and restoration on time (13 months) and within budget.

The parking lot, which is shared with the Illinois Attorney General's Office, was removed and rebuilt, incorporating retaining walls, bollards, security walls, surveillance and traffic circulation improvements.

Asbestos-containing material was removed from the flooring, pipes and window caulking.

The building required new electrical and HVAC systems. Because it shares a multi-building steam loop, the new heating system utilizes this heat in a new, forced-air system. A new sprinkler system was installed in the first, second and third floors, plus the attic. All of this work was performed inside walls and crawl spaces between floors without disturbing historic walls, ceilings, floors and woodwork. An original one-man elevator was removed, and new ductwork was installed to allow for cleaner air flow.

Over the years, fluctuations in humidity in the building took its toll on important documents and plaster murals and even caused a wooden column to split. K&L took great care during construction to protect historic material and finishes by climate-controlling all rooms and spaces. A new climate-controlled room was built in the basement to house the historical library collections.

While working in the basement to prepare the area for the new mobile storage system, K&L discovered a high water table. To solve the problem, sub-terrain groundwater collection systems were installed in two rooms to prevent future water leakage in the basement.

The project also included new restrooms in the basement and on the second floor, and renovation of all other public restrooms in the building. Existing marble was removed, cleaned and reused to meet ADA codes in lieu of incurring the expense of new marble. Life safety items were upgraded and remodeled. The roof received structural modifications as necessary.

Historic preservation of public spaces, courtrooms, library, interiors and support spaces for the Court returned those areas to their original 1906 colors and appearance, including detail down to silver flaking on carvings in the woodwork. Restoration professionals spent countless hours painstakingly cleaning century-old tapestries and removing, repairing, cleaning and restoring the light fixtures. All original doors, plaster murals, stone, marble, art glass, hardwood floors, painted finishes and elevator were also restored.

Korte & Luitjohan Contractors, Inc., is proud to have played a part in this important renovation of our State's Supreme Court Building in restoring it to its original splendor.
