SPIE specialises in electrical engineering, mechanics, climate control, energy, communication networks and infrastructures.

SPIE was responsible for the technical renovation of a number of buildings at Pegasus Park in Diegem (Brussels). During the pre-commissioning phase, the ducting within these buildings had to be cleaned, to ensure that the ventilation system would be able to immediately provide healthy indoor air. Hamster Cleaning completed the work and removed all debris left over from construction from the air ducts. Using extensive footage, the difference between pre-cleaning and post-cleaning was shown in the report provided by Hamster Cleaning.
