Main project Of GNEE
GNEE specializes in structural steel engineering for infrastructure, commercial buildings, industrial facilities, and offshore & marine engineering. Leveraging integrated capabilities in connection detailing and construction management, GNEE has established a systematic project execution framework that encompasses design optimization, structural detail design, and full-process construction control.
In terms of detailing and connection design, GNEE utilizes a BIM-based collaborative design platform combined with Tekla Structures for 3D modeling and steel connection detailing. By integrating parametric modeling with construction sequence simulation, GNEE achieves precise, end-to-end control spanning from structural detailing to fabrication and on-site erection.
