# Cleaning and window cleaning at the DIFFER building

NWO-I sought a single-company framework agreement for cleaning and glazing at the DIFFER research building in Eindhoven. The building is about 10,000 m²; only some laboratories are included because of sensitive research materials. The scope covers regular cleaning, floor care, windows, solar panels, patio and roof. The initial term was 36 months with two optional one-year extensions. The official API now marks the procurement as awarded, but the materials reviewed do not identify the awardee or award amount.
