Gustav Pegel and his team played a significant role in the construction boom that emerged in Germany just after the German-French war. This led to the emergence of the ‘Made in Germany’ brand name, which was based on high-quality workmanship, sophistication, and durability. Pegel executed numerous infrastructure and industrial projects, storage and public facilities, administration offices, and hospitals.

From the 50s to the 70s, Pegel was involved in rebuilding Berlin and completed challenging flagship and landmark developments such as the Berlin Tegel Airport. The company then exported its expertise to the Middle East, specifically Saudi Arabia, United Arab Emirates and Oman, participating in the construction boom of the 70s and 80s. During this period, Pegel forged strong, long-lasting relationships with key players in the construction industry, both in the public and private sectors. Prestigious large-scale projects such as the King Khalid International Airport in Riyadh were executed during this time.

After the reunification of Germany in 1989, Berlin once again experienced a construction surge, with countless projects executed, and extensive infrastructure projects upgrading the former Eastern part of the country. In the 2000s, Pegel contributed to exciting construction projects that marked the decade in the United Arab Emirates, alongside leading industry players. Pegel's success can be attributed to its organizational skills, coupled with committed, reliable, and precision-centered individuals from the client to the worker.
