Project Description

The BB Tower is the new headquarter office for YTL Corporation Bhd located along Jalan Bukit Bintang, in the heart of Kuala Lumpur. This 0.75 acre project development consists of a 32-storeys office tower over four basement level car parks, with a total built-up area of 25,800 m2.

The Requirement: To connect precast concrete staircases and walls without denting the appearance of architecture.

The Solution

Partnering with Invisible Connections, Halfen-Moment Malaysia offered an innovative solution by providing TSS41 to connect all precast concrete staircases with hidden connections in the walls for the entire building, offering clean streamlined aesthetics architecture, without using integral corbels.

The TSS units were developed as a connection detail between precast landings or stairs and walls in stairways, and all that is required in the wall is a recess. The inner tube is retracted into the unit during erection, to be pulled out into the recess when the precast element is in the correct position. A safety stop will prevent the inner tube from excess protrusion. A rubber pad at the support in the wall is available in order to reduce the impact sound transfer from the stairs to the walls. It provides hidden connection, quick erection, and no site work is necessary with bolts, welding or mortar.

Other than TSS41, Halfen Cast-In Channels with ETA-16/0453 approval & CE Marking approvals were supplied for façade fixings, while Moment® Coupler and Plakabox were also used in the development for connection reinforcement.

The Result

The TSS connectors were supplied to YTL for precast and installation work. It was chosen in compliance with the high quality finishes, as Invisible Connections products are being used to satisfy robust, quick, clean and efficient connection.
