Concrete is a conventionally used material for construction while steel is now gaining momentum for its flexibility and reduced construction time. Both concrete and steel framed structures have environmental issues associated with their use, including a high embodied energy in their manufacture.

Steel, while having a high lead time, is known for its fast erection on site. However, steel needs fire protection whereas within concrete this is inherent. Prefabrication of steel can allow thin film intumescent coatings to be applied offsite.
