Sheikh Zayed Bin Sultan Street

(formerly known as Al Salam Street Upgrade)

Transgulf Readymix is one of a handful of suppliers worldwide that have successfully completed a project that exceeds one million cubic meters of concrete.

An on-site batching plant was installed to build this project. This upgrade includes a 2.2 km long cut and a cover tunnel, and a 1.2 km road leading through the tunnel. This project is expected to double the streets current capacity from 3,000 to 6,000 cars/hour including a nonstop “green drive” that has no traffic signals.

The busiest phase was in May 2010 when 72,000 m³ of concrete were delivered in the midst of the hottest season. Steam curing was incorporated for 4,000 precast pre-stressed I-beam concrete girders while achieving 44 mPa within 16 hours.

Samsung C&T was grateful for Transgulf Readymix’s perfect safety record for this project. We had absolutely no safety incidents and it was one of the highlight mentions in Samsung C&T’s appreciation letter.

Expolink Metro Route 2020

The Route 2020 is an extension of the existing Dubai Metro Red Line from the Nakheel Harbor and Tower station to the Expo 2020 site. The alignment for the project includes approximately 2 km of bored tunnel excavated by a tunnel boring machine (TBM) and 10 km of elevated structures, including five elevated stations and two underground stations. The project aims to link up the Dubai Expo 2020 site with the city’s existing metro services.

The construction of elevated stations, underground stations, and cut & cover tunnel sections comprises of raft slab, concourse slab, and roof slab cast in stages with connectivity to diaphragm walls. The raft foundation of each underground station was divided into 24 segments with an average thickness of 3.50m and over 36,500 m³, The excavation of the cut & cover tunnel was supported by shotcrete. As for the pilecaps and piers, over 200 were cast using Transgulf Readymix’s concrete from Nakheel Harbor to the Expo 2020 site.

Strategic Enhancement Tunneling Programme (STEP) – Abu Dhabi

This tunneling project is one of the largest of its kind in the middle east and it’s laid out to expand the city’s sewerage network as part of the Plan Abu Dhabi 2030 with an investment of 5.7 billion dirhams. . Measuring at 45 km long with a 6 meter diameter, the tunnel links the northern part of Abu Dhabi Island at a depth of 24 m to the mainland at a depth of 80 m.  The previous capacity of the city’s sewerage treatment system is 450,000 m³ of wastewater/day and the theoretical capacity with the tunnel expansion would raise that figure to 800,000 m³. The tunnel is designed for a 100 year operating service life in an aggressive environment exposing the concrete elements to high concentrations of chlorides and sulphates; This challenge was overcome with researching and developing the proper mixes for various exposure conditions.
