Having built up a list of local construction firms working on the giga-projects, GSN has analysed the shareholding records for several contractors, using data provided by Diligencia in a partnership to help sharpen understanding of those involved. It shows that the companies most heavily involved are often decades old, with the exception of Saudi Real Estate Infrastructure Company (Binyah). They are mainly in private hands (Red Sea International is an exception) and often held by generations of the same family.
