Building Jordan: SIGMA


This feature is part of a series highlighting the most prominent engineering and design consultancy firms with headquarters in Jordan or that have a significant presence in the Kingdom.


Founded: 1975

President and Managing Director: Hani Hakki

Number of employees: Approximately 320

Offices: Jordan, Palestine, Saudi Arabia, Qatar, Libya, Iraq, and Yemen


SIGMA was formed through the merger of three local companies back in the 1970s. Sole ownership was later taken on by Hani Hakki, who today leads a company that’s been responsible for some of the most impressive construction projects in Jordan and the wider region.

Within Jordan, SIGMA has designed numerous high profile projects, including the Amman Grand Hyatt Hotel, the Mövenpick in both Tala Bay and the Dead Sea, and is of course now famous for the Abdali project’s 50-storey, 427-room Rotana Hotel, which at a height of 188 meters, is now the tallest building in Jordan.

SIGMA has also recently designed the Al Fahares Development Project. Construction of the 2 kilometer stretch along the Dead Sea has not yet begun, but it’s set to be a significant addition to the Dead Sea’s beachfront. The development will include a beauty and treatment hotel, a heritage site, a museum, residential villas, a promenade, and a five star hotel.

More further afield, SIGMA won a bid to design the Advanced Learning School in Saudi Arabia over American, Turkish, and other Arab firms.

Despite SIGMA’s recent achievements, the last few years have been challenging with the sector hit hard by the global financial crisis. “It affected us quite a great deal,” said Ismail Hakki, director of Development and Planning at SIGMA. He explained that of the four buildings they were commissioned to design for the Abdali development, two were put on hold.

But matters now seem to be back on track for SIGMA, with several new promising projects in the pipeline. If all goes according to plan, Hakki expects the company will double in size in the near future.

Hakki said his firm now intends to expand its reach internationally. “We’re exactly in the transition now where we’re focusing more on the international market,” he explained, adding that he expected the number of SIGMA’s international projects will overtake domestic ones by next year.
