ESA offers a complete design service from the concept stage to final design and drawings for a project or development.

Our professionally registered designers apply the latest design methods and the designs comply in all respects with local as well as international codes and standards for hollow core slabs as set by the Fèdèration Internationale de la Prècontrainte.

If the client wishes to utilise their own design engineer to do the design, ESA will provide any assistance and design information to enable an economical solution to their project.
