Tekla is a software platform for the construction industry that provides tools for building information modeling (BIM), structural engineering and construction management. Tekla was developed by a Finnish company called Tekla Corporation, which was acquired by Trimble Navigation in 2011.

Tekla software is used by architects, engineers, contractors and construction professionals to design and manage building projects. It allows users to create 3D models of buildings and structures and share those models with other members of the project team. Tekla software also includes tools for cost estimating, scheduling construction activities, and managing materials and resources.

Tekla is widely used in the construction industry, particularly in the areas of detailed steel design and precast concrete design. The software is known for its accuracy and reliability, as well as its ability to handle complex construction projects.
