TTM Post Tensioning (TTM), a KBW Investments company, has completed a post-tensioning (PT) contract worth QR1.5 million ($411,500) for the K&H Al Mana 03 mall in Doha, Qatar.

The retail and hospitality complex, with confirmed anchor tenants like Carrefour and international food and beverage outlets, includes an expansive cinema.

“The initial mall designs used conventional reinforced concrete slabs, which proved to be unsuitable for the cinema because the span was inadequate. TTM was engaged to convert the original proposed concrete slabs to PT slabs, leading to a significant 20 per cent reduction of the overall structural cost,” said Sameel Hamza, chief operations officer of TTM.

All of the components, including the strands used in the project, were produced in the TTM factory in Milan, Italy.

TTM was awarded the job in February and completed its work within the timeline.

“The original foundation plans, at a thickness of 1,200 mm, was significantly improved upon for a resulting thickness of 700 mm due to TTM’s implementation of PT rafts across approximately 3,230 sq m of car park. This shift in design not only saved thickness, it allowed for a hefty cost reduction in materials like steel and concrete, together with a shorter turnaround time and required less onsite labour,” added Hamza.

The mall, scheduled to be fully complete in approximately six months, consists of basement and ground floors, a mezzanine and skylight roof with a total built-up area of 11,773 sq m.
