The design of buildings includes a specialised field of engineering to evaluate and design the structure. For a new building design, structural engineers model the structure to determine the sizing, strength and stability of foundations, columns, beams, slabs, and roofs. This process accounts for local building codes, properties of construction materials, soil and climate conditions, and architectural design.

Petram also works on projects with existing buildings that need repair or retrofitting. The design proposal addresses the wear and tear of the existing system and provides a solution for increased longevity of the building.
