Background and Qualifications

About Paul Gaston, Construction Expert

Paul Gaston is a construction expert with more than 30 years in commercial, municipal, healthcare and retail construction. He holds an active City of Chicago general contractor license, has been a Carpenters Local 10 journeyman since 1989, and has served as a General Foreman for the Chicago Department of Aviation at O'Hare International Airport since 2007.

From Carpenter to General Foreman

Paul Gaston learned construction the way most good builders do: with tools in hand. He joined Carpenters Local 10 in 1989 and spent the following years framing, installing millwork, hanging doors and finishing interiors. Between 1994 and 2004 he worked as a lead carpenter and foreman for several firms, leading carpentry, framing, millwork and finish work on commercial, retail and residential projects, including work for Shriners Hospital, Marshall Field's and Jewel-Osco.

In 2004 and 2005 he served as Project Manager and Superintendent for Oakley Construction Contractors, managing commercial and educational facility upgrades that included accessibility modifications and flooring. From 2005 to 2007 he was a Foreman and Construction Supervisor for the City of Chicago Department of General Services, supervising renovation and maintenance across City facilities, including public safety buildings and offices.

General Foreman at O'Hare International Airport

Since 2007 Paul has been a General Foreman for the City of Chicago Department of Aviation at O'Hare International Airport. He oversees large-scale renovation, maintenance and construction work across terminals, concourses and public facilities, and directs a team of more than 25 skilled trades responsible for carpentry, flooring, plumbing, electrical and finish work.

The role demands constant judgment about workmanship. Work has to be done right the first time, inspected before it is turned over, and corrected quickly when it is not, all in a facility that stays open to the public. That daily experience of planning, checking and correcting work by many trades is the foundation of his expert opinions.

How Paul Approaches Every Engagement

Paul applies the same approach whichever side retains him. He reads the documents before he forms a view, inspects the work before he describes it, and separates what he observed from what he was told. Where a question falls outside his experience, such as structural design or engineering analysis, he says so early so that counsel can bring in the right professional. His services page describes the scope of a typical engagement.
