In 1827 Demut-Malinovsky and Pimenov sculpted decorations for the arch of Rossi's General Staff Building. Pimenov was particularly responsible for the chariot of Glory on the attic of the arch. Pimenov's later work included the chariot of Apollo for the Alexandrinsky Theatre between 1831 and 1832, and statues of Homer and Plato for the Imperial Public Library over the same period. In 1830 he had produced a similar composition to the General Staff Building's one for Vasily Stasov's Narva Triumphal Arch, but by this time he had fallen out of favour with Emperor Nicholas I, supposedly over Pimenov's portraits of Nicholas and his wife Alexandra Feodorovna. Nicholas criticised Pimenov's characters for the Narva Arch as being too thin, and ordered a new competition. Pimenov was forced to resign from the Academy, though he was still able to complete his design for the Arch, sculpting the figures of "Glory", and supporting characters in 1832.
