TTM has been awarded a $275,000 (QAR1m) post-tensioning (PT) contract for C09 Lusail Marina in Qatar.

The firm, which is owned by Saudi Arabia’s KBW Investments, will be responsible for the design and implementation of PT technology at the development.

TTM was appointed by Al Wefaq Engineering, the contractor and developer of the $30.2m (QAR110m) project.

C09 Lusail Marina, which originally employed reinforced concrete (RC) slabs, has been redesigned by the PT specialist as part of the new contract.

Sameel Hamza, chief operations officer at TTM, explained: “The C09 Lusail Marina project was initially designed with the conventional method of RC slabs. TTM proposed that introducing PT would result in developer cost-savings, together with a much more efficient timeline of execution.

“TTM was awarded the [contract] based on the significant financial and technical benefits of implementing the PT method into the structure’s design,” he continued. “A PT system poses benefits for all parties involved in both the immediate term, such as the reduction of labour required on site, and in the long term, as slabs are designed crack-free, thereby enabling waterproofing.”

TTM estimates that the integration of PT technology at C09 Lusail Marina will result in a 25% cost reduction. It also stated that a steel-laden RC slab-beam installation would take up to 50% longer to build.

“All TTM strands are produced at [its] factory in Milan, Italy,” added Hamza. “The only PT company in the world that produces steel wire in house, the value proposition of TTM’s technology begins at the material stage.”

TTM’s project redesign for C09 Lusail Marina began in July 2016, and the firm is targeting a December 2016 completion date.

C09 Lusail Marina will boast a total built-up area of 2.59ha, and is scheduled to complete in Q2 2017, according to Al Wefaq.
