College of DuPage, Community College District No. 502, is requesting sealed bids for interior and exterior window washing services at its Main Campus and three regional centers, with bids due August 27, 2026 at 1:00 p.m. Central Time. The College has established a 30% aspirational Business Enterprise Program (BEP) participation goal for certified minority-owned, women-owned, and persons-with-disabilities-owned businesses.

The scope covers cleaning of interior and exterior glass surfaces—fixed and operable windows, block glass entrance doors, and reflective glass surfaces—across five locations: Main Campus (East and West), Carol Stream Center, Westmont Center, and Naperville Center. The contractor must furnish all labor, equipment, supplies, materials, and services. Work is scheduled across two years with an optional one-year renewal, requiring three cleaning cycles annually: exterior cleaning in October/November, combined interior and exterior cleaning in December/January, and exterior cleaning in April/May. All work must be performed during college regular business hours (8:00 a.m. to 5:00 p.m., Monday through Friday) by the contractor's employees, with a supervisor fluent in English on-site at all times. Prices are firm for the initial two-year contract period; renewal-year price increases may not exceed 3% with supporting documentation, submitted no later than six months before expiration.

The contractor must comply with Illinois Prevailing Wage Act requirements and maintain commercial general liability, automobile liability, and workers' compensation insurance with minimum coverage of $1,000,000 per occurrence and waiver of subrogation. The contractor is responsible for all damages to college property.

A pre-bid conference is scheduled for August 12, 2026 at 11:00 a.m. Central Time via Zoom (non-mandatory but highly recommended). Written questions are due August 13, 2026 at 12:00 p.m. Central Time.
