Every Level of the Organization

Contractor conduct disputes ask how decisions were made at every level of a project: in the field by the crew, by the foreman directing the crew, by the superintendent coordinating trades, and by the project manager responsible for schedule, cost and documentation. Paul has worked at each of those levels.

Superintendent and Project Manager

As Project Manager and Superintendent for Oakley Construction Contractors, Paul managed commercial and educational facility upgrades, including accessibility modifications and flooring. That role carried the responsibilities at the center of most contractor conduct disputes: scheduling and coordinating subcontractors, maintaining site records, managing changes, checking work and closing out projects.

Public-Sector Supervision

With the City of Chicago, Paul supervised renovation and maintenance across City facilities, including public safety buildings and offices, and was responsible for adherence to safety, accessibility and construction codes. At O'Hare he oversees large-scale renovation, maintenance and construction projects across terminals, concourses and public facilities, directs a team of more than 25 skilled trades, and coordinates work so that airport operations continue without interruption.

Public-sector work is heavily documented and inspected. That experience informs how Paul evaluates a contractor's records and quality control.
