Tianjin Financial Growth
The construction of CTF Financial Center in Tianjin (China) being actively underway. The construction passed of no return point, when it is easier to finish it than to conserve. At the beginning of 2016 were completely erected the building podium and a couple dozens of storeys. Given the tower’s profile, the traditional scaffold and climbing formwork cannot be used during the construction stage, thus making the tower one of the most challenging skyscraper construction projects ever seen in China. The geometric design of the façade structure is a significant complexity of the development. Careful layering and arrangement in the tower’s facade is designed to allow more efficient buildability.
Tianjin CTF Finance Centre is designed as a massive 530m tall edifice. Aside from its tremendous height, the detail-designed and intricate building façade is one of the most significant components contributing to the upcoming icon of the district.
The overall façade consists a total of staggering 14,000 components originally, with the geometric design of the façade structure which greatly increased the difficulty during the construction. However, with the help of the latest BIM technology, the building process is now speeded up substantially. Furthermore, the surface geometry of façade is divided in 1/8 for repeated modelling, which rationalizes the complexity of geometry and enhances buildability.
The tower’s quadrate-shaped bottom makes intelligent use of space, with the shape of the tower becoming further and further narrow as it stretches to the upper levels, creating a uniquely beautiful irregular spiral appearance. In terms of functions, the retail podiums and offices are designed for the lower storeys running from the G/F to level 48, where the interior layout is more rectangular in shape which allow the tower to better facilitate the functions as shops and workplaces.
Furthermore, materializing the spiral shape of this super high-rise tower, the whole structural and layout is put into consideration. Specific structural loading based on accurate calculation is put into practice to enhance efficiency and avoid vibration of the building.
Furthermore, the tower is split to cater various functions including retail, office, serviced apartments, hotels and restaurants, adding diversity and multi-purpose to the development. MEP floor is arranged to separate the building usage as well as security control.
The subletting schedule is a tool for procurement management. It is prepared before the contract was awarded. This schedule comprises the trades of works to be subletted, and drawings to be ready by Consultants in corresponding with Master Programme. The schedule includes all NSCs, Direct Contractors and the Domestic Subcontractors, which will be reviewed regularly to avoid any late nomination.
Since this is a cost plus contract, the procedures on award of subcontracts is closely monitored and participated by Client, Consultants and the Main Contractor. The dispatch of document, interviews, clarifications and assessment will be carried out under the team work approach. We believe with such close collaboration works among different parties no time delay will occur in this process.
Tianjin CTF Finance Centre is 530m tall skyscraper consisting 97-storey towers, 5-storey podium and 4-storey basement. It is a comprehensive development project comprising retail, office, hotel, and serviced apartment. Its design accentuates its mixed-use nature.
The project is located in Tianjin Economic Development Area with total GFA of 389,980 sq. m. including aboveground GFA of 291,610 sq. m. and underground GFA of 98,370 sq. m. Completion of the construction is planned in 2018.
