Construction Progress Update 22nd June 2009...
We are now 103 weeks into the 189-week construction phase of the project, and the Works remain “on programme”.
On all SKANSKA sites our target is ZERO ACCIDENTS – on the Heron Tower Project we are working hard to achieve this. After two years of demolition and new construction work our overall Safety Statistics (RIDDOR classification) are as follows:
- 22 minor accidents
- 1 reportable
- 7.5 lost days out of 700,000 man hours worked
Every incident which could affect the health and safety of anyone on site or the general public is investigated and recommendations for improvement are implemented so that we all benefit from lessons learned. The site team is actively encouraged to report every ‘near miss’ incident so that corrective action can be taken and the highest possible standards of safety are maintained.
Structural steel frame facts...
- Structural steelwork started in October 2008 and is planned to be completed by March 2010.
- the frame is erected up to level L22 (top floor level is L47).
- the building height stands at 94 metres (final height 203 metres – excluding the mast).
- almost 7,000 tonnes of steel erected so far (12,000 tonnes in total).
- About 3,600 individual pieces of steel have been erected (7,200 pieced in total).
Life at the top...
Sanding down – in preparation for final painting.
Tower cranes facts...
- Crane climbs: each crane will be climbed (and progressively tied to the building) 5 times in total as the building height increases.
- Two climbs have been completed successfully so far – next climb scheduled for mid-July (subject to fair weather conditions!)
- Currently, the cranes stand at 102 metres high (TC Nos. 1 &3) and 114 metres high (TC No. 2).
Inside the building...
Office air conditioning, fire sprinkler system, and lighting & power systems are currently being installed progressively on levels L2 to L10.
At Ground floor level...
The 40-tonne hydraulic excavator with a specially adapted telescopic grab has now been demobilised – after removing about 20,000 cubic metres of earth and rubble in preparation for the new basement construction.
Below ground...
The B2 basement slab and walls are now completed.
The B3 basement construction has started...
In total, approx. 6,000 cubic metres of concrete will be needed to construct the three basement levels.
