TTM Post Tensioning, part of Saudi Arabia-headquartered KBW Investments’ business portfolio, has completed a $412,000 (QAR1.5m) post-tensioning contract for the K&H Al Mana 03 mall project in Qatar.

Located in Doha’s New Salata area, the mixed-use retail and hospitality development will include anchor tenants such as Carrefour, international food and beverage (F&B) outlets, and an expansive cinema installation.

Commenting on the project’s post-tensioning package, Sameel Hamza, TTM’s chief operations officer, said: “The initial mall designs used conventional RC slabs, which proved to be unsuitable for the cinema’s requirements because the span was inadequate. TTM was engaged to convert the original proposed concrete slabs to PT slabs, leading to a significant 20% reduction of the overall structural cost.

“All of the components, including the strands used in the K&H Al Mana project, were produced in the TTM factory in Milan, Italy, ensuring that only the best-quality materials were sourced for this structure,” he added.

The post-tensioning contract was awarded to TTM in February 2016, with the redesign commencing immediately thereafter.

A statement issued by TTM revealed that it completed its scope of work “well within the expected client-specified timeline”.

“TTM allocated a total of five team members to [the] K&H Al Mana mall development, including a structural engineer, project managers, supervisors, and technicians, with the structural PT slab design executed in house,” Hamza explained.

“The original foundation plans, at a thickness of 1,200mm, [were] significantly improved upon for a resulting thickness of 700mm, due to TTM’s implementation of PT rafts across approximately 3,230m2 of car park. This shift in design not only saved thickness, [but also] allowed for a hefty cost reduction in materials like steel and concrete, together with a shorter turnaround time. [It also] required less onsite labour,” he concluded.

The mall, which boasts a total built-up area of 11,773m2, comprises a basement, a ground floor, and a mezzanine and sky-light roof.

The project is due to complete in 2017.
