Distance first: slump and retarder
Trucks take Al Khail Road and then Ras Al Khor Road toward the harbour. At peak hours that drive lengthens a lot. We set the retarder dose for the expected travel time plus the wait on site, and we fix the target slump for the hour you pour, not the hour we batch.
For a large raft, tell us early. We would rather start the first trucks in the evening, when the roads are lighter and the air is cooler, than send a load into the afternoon queue at Ras Al Khor. A longer haul also means the dispatcher needs more trucks on the road at once to keep the same rate at the pump.
Waterfront towers in numbers
A 600 m³ tower raft is 50 truckloads. At that size the job is a continuous chain: trucks loaded at Al Quoz in sequence, a queue staged inside the site boundary, and two pumps if the raft layout allows. The site sets the placing rate, and our dispatcher adjusts departures as soon as it changes, so no truck sits for long with a turning drum.
Typical floors are smaller and steady. A 43 m boom works the podium levels, a 57 m boom covers longer reach from the perimeter road, and the upper floors go to a placing boom fed by pipeline.
Ground and neighbours
The district is on coastal ground with saline, shallow groundwater. Piling, shoring and substructure mixes are designed for chloride and sulphate attack with GGBS and a low water/cement ratio, with the cover your consultant sets.
Next door is the Ras Al Khor wildlife sanctuary. Washout, spillage and truck idling are things to agree with the master developer before the first load arrives, along with the internal route for mixers.
Questions from Dubai Creek Harbour sites
- Is the trip from Al Quoz too long for a big raft?
- No, but it changes the mix and the fleet. We dose the retarder for the travel time and put enough trucks on the road to keep the pour continuous.
- Who approves delivery hours in Dubai Creek Harbour?
- The master developer controls site access and truck routes. Check with them and share the approved slot with us.
