Commercial and Institutional Work

Chicago Commercial Construction Expert

Paul Gaston is a Chicago commercial construction expert with experience on retail, healthcare, educational, municipal and airport projects, including work for Shriners Hospital, Marshall Field's and Jewel-Osco and nearly two decades at O'Hare. He evaluates workmanship and contractor execution on Chicago commercial and institutional work against the specifications, submittals and adopted code.

Chicago Commercial Experience

Paul's commercial experience in Chicago spans three decades and several kinds of owners. As a lead carpenter and foreman he led carpentry, framing, millwork and finish work on commercial and retail projects, including work for Shriners Hospital, Marshall Field's and Jewel-Osco. As a superintendent he managed commercial and educational facility upgrades. As a City of Chicago foreman and general foreman he has supervised renovation of public safety buildings and offices and, since 2007, terminals and concourses at O'Hare International Airport.

Commercial Work Paul Evaluates

  • Retail and restaurant build-outs and remodels
  • Healthcare and institutional renovation
  • Office tenant improvements in Chicago's downtown and neighborhood buildings
  • Public facility renovation and maintenance work
  • Interior partitions, ceilings, doors and hardware, millwork, flooring and finishes
  • Furniture and fixture installation in public areas

Institutional and Public Work

Institutional and public projects in Chicago are heavily specified and inspected, with owner standards, phasing requirements and extensive documentation. Disputes often turn on whether the contractor followed those standards and procedures, not just whether the finished work looks acceptable. Paul's years supervising City of Chicago facility work give him practical knowledge of how such projects are run and documented.

Specifications and Submittals

Commercial work in Chicago is usually governed by detailed specifications, approved shop drawings and submittals, and sometimes owner or landlord building standards. Paul reviews these together in date order with RFIs and change orders, so that each disputed item is compared with the requirement that actually applied when it was installed.

Subcontractor Disputes

Commercial projects involve many subcontractors, and workmanship disputes often run between the general contractor and a subcontractor over backcharges, or among subcontractors whose work meets at the same location. Paul identifies which trade performed each disputed item, how adjacent work affected it, and what the subcontracts required. His knowledge of Chicago union trade practice helps identify who typically performs which work. See Chicago renovation defects and Chicago repair cost evaluation.

Turnover and Acceptance

Many Chicago commercial disputes arise at turnover, when an owner, landlord or tenant refuses to accept a space or withholds payment over open items. Paul reviews punch lists, close-out documents and correspondence to determine which items were genuinely incomplete or deficient, which were corrected, and which were added after the fact. That review often narrows a long list to the items that matter.
