Route and retarder
Fifteen kilometres across the city is the point where travel time starts to show in the slump. For summer day pours we set a retarder dose for the trip and the hour, and keep the slump target at discharge. If your consultant has a placing-temperature limit, a night pour is the simplest way to meet it.
Mid-afternoon in summer is the worst slot: hot concrete, heavy traffic on both approach roads. If you cannot pour at night, an early start gets most of the volume placed before the heat peaks.
Gate and access inside the zone
Silicon Oasis is run by its own authority, and many plots sit inside fenced campuses with a security gate. Check with the zone and the building management for any delivery permit, allowed hours and the gate trucks must use. We need that information the day before, including the name of the person who opens the gate.
Plots on the grid usually have a clear side road for the pump. That makes the setup simpler than in older parts of Dubai.
Frames, raft foundations and pump reach
Residential buildings and campus blocks here are larger frames. A 400 m³ raft is 34 trucks; at a pump rate near 40 m³ an hour that is a ten-hour continuous pour with a truck every eighteen minutes or so. For pours this size we agree a dispatch plan and a backup pump before the day.
Upper slabs on a mid-rise block are usually within reach of the 43 m boom. The 57 m boom is the right call when the pump must sit far from the building face or the slab is wide. For tall frames, a placing boom on the slab fed by a static line is often cleaner than moving a mobile pump each floor.
Questions from Dubai Silicon Oasis sites
- Can you supply a continuous raft pour in Silicon Oasis?
- Yes. Give us the volume, the pour rate your crew can handle and the start time, and we plan the truck sequence and a backup pump.
- Do I need a gate pass for trucks?
- Often, yes. Check with the zone authority and building management, then send us the pass details.
