The Aylesford-based firm used 100 separate tiles, each 2.1x1.22m, creating over 250m2 of digital imaging.
The frieze is mounted on hoardings surrounding the first building site in a 20-year redevelopment of the hospital. It features a series of images of patients by photographer Richard Bailey, which are interspersed with Great Ormond Streets "The child first and always" slogan.
ESP selected pre-cut sheets of 3mm Dibond rigid aluminium laminate due to the substrates ability to withstand the rigours of the building site.
The firm also screen printed a UV over-varnish to give further protection.
ESP managing director Stephen Hood said the opportunity to do work for Great Ormond Street was "a dream come true".
