Site preparation and crushing of concrete rubble for UNDP's Rubble Removal from the Gaza Strip programme (Package 4). MACC prepared a 15,000 m² crushing and storage pad and crushed 111,000 tonnes of war debris into graded aggregate of 10–80 mm, separating out reinforcing steel and plastics.
Scope of work
- Pre-screening of rubble on an 8 cm bar sieve
- Crushing of 111,000 tonnes of concrete rubble to 10–80 mm, with removal of reinforcing steel and plastics
- Dust suppression during crushing
- Crushing and storage pad of 15,000 m²: cut and fill, compaction to 95%, 0.12 mm polyethylene sheeting and a 25 cm crushed-aggregate layer
- Stockpiling of crushed material to a height of 6–8 m
- Weighing of crushed output at the nearby dump-site weighbridge
- Laboratory testing of the crushed material at two laboratories, and a stakeholder workshop
Technology and key components
- Mobile jaw crushing plant of at least 150 t/h with magnetic separator, hydraulic jaw and vibrating feeder
- UXO awareness training for site staff, UXO risk insurance and coordination with UNMAS on unexploded ordnance
