Greater Peoria Contractors and Suppliers Association (GPCSA) is an organization of qualified construction contractors and industry-related companies dedicated to skill, integrity, and responsibility. The fundamental goal of the Association is to address the needs, goals, and concerns of its members, thereby improving the quality of the local construction industry.
The Association provides a full range of programs and services including, but not limited to, networking opportunities, labor relations and collective bargaining, educational and professional development, plan room accessibility/lead generations, legislative and political awareness, as well as community connections, meeting space, and print scanning.
Much of Poettker Industrial’s projects include infrastructure work for electrical substations and transmission lines. In 2025, Poettker Industrial built 3,954 substation foundations across 461 acres and 1,074 transmission towers over 215 miles.
Poettker Industrial executed projects across six states, seven of which were renewable energy projects. For these projects, the team and trade partners are building foundations, resurfacing the area, driving piles, and installing below-grade electrical for new solar fields.
Continuing the community outreach legacy of Schlautman’s father, Charles Poettker, Poettker Industrial co-hosted an annual golf classic benefitting Big Brothers Big Sisters of Southwestern Illinois. With 70 participating teams and 38 Gold Sponsors, the event raised $61,000 for the nonprofit organization. Poettker Industrial also supports Junior Achievement as a Program Sponsor of the JA Trades STEAM Experience, an interactive learning experience that teaches students about trade career opportunities.
“I’m excited to see Poettker Industrial continue its expansion into the renewable energy sector, as well as grow our team to meet the energy needs of our clients,” said Trey Wiegmann, Vice President of Construction Services at Poettker Industrial. “We’re proud to support our clients in new states and provide the infrastructure they need to expand their service offerings to their thriving communities.”
