Reducing the carbon footprint of telecom towers |
 |
VSL has provided design, precasting and construction services for a pilot project to build eight of the patented, award-winning Ericsson Tower Tubes (ETT) in Saudi Arabia. The towers house base stations and antennas. They have a smaller footprint and a lower environmental impact than a traditional steel tower. |

D-walls construction in Hong Kong |
 |
The Entasis-Intrafor Consortium has built 1.5m-thick diaphragm walls to depths of 55m for the West Kowloon Terminus approach tunnel (south) as part of Hong Kong’s Express Rail Link. Work also includes the installation of shear pins, fissure grouting and the removal of an existing breakwater. |

Avoiding disturbance in Hong Kong |
 |
Construction of a two-storey basement in Sheung Shui in Hong Kong brought considerable challenges as the adjacent three-storey buildings stood on shallow friction concrete piles and pad footings. Intrafor’s careful choice of methods and equipment avoided any disturbance or settlement of the surrounding buildings. |

High-speed wall in Hong Kong |
 |
Intrafor has taken just four months to build a 1.2m-thick diaphragm wall with a total volume 24,000m³ and a depth reaching 60m below sea level in Hong Kong. The design and construct project was for the basement of a new residential development in Tseung Kwan O for leading property developer Sung Hung Kai. |
|
 |
Intrafor has completed its deepest ever shaft, finishing four months ahead of schedule. The 91m shaft is part of Hong Kong’s Harbour Area Treatment Scheme. Intrafor developed patented sacrificial void formers for the project. Achieved tolerances on verticality were extremely low, well within requirements, and the jointing between the panels was made with high quality, thus avoiding the need for expensive and time consuming concrete finishing or trimming. |

Diaphragm wall for the Central Wanchai Bypass in Hong Kong |
 | Intrafor is working on a 21,000m³ diaphragm wall project: the Central Wanchai Bypass Central Interchange. Challenges include busy traffic, buried seawalls and low headroom, for which Intrafor has developed a special rig. A BC40 cutter and two excavation cranes have been mobilised for the project. | |
 | Intrafor has secured a major contract to construct one of the most challenging sections of the MTR’s new Express Rail Link (XRL), a part of Contract 820. The section passes under a densely populated and heavily piled area. Intrafor’s responsibilities encompass foundations, ground treatment and diaphragm wall shaft work. | |
