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