As group chief executive officer of Arabtec Holding, Hamish Tyrwhitt has successfully capitalised on the momentum the business began to build in Q1 2017, securing revenues of $2.5bn (AED9.2bn) in the last financial year.

The UAE-headquartered construction giant worked as the main contractor on projects including the Louvre Abu Dhabi, Dubai’s Damac Heights and Oud Muteena Villas, and Aramco Villas in Saudi Arabia.

The company’s ongoing portfolio includes work on Abu Dhabi’s Midfield Terminal Project in a joint venture (JV) with CCC and TAV, Bahrain International Airport in a JV with TAV, and Jordan’s Saraya Aqaba in a JV with CCC.

Tyrwhitt says that Expo 2020 Dubai is proving crucial for the local sector: “Expo-related development projects are expected to exceed $33bn (AED121.2bn), with more than 2,000 new structures being built in the UAE. [The event] is one of the single biggest opportunities for Arabtec Group within the next [year].”
