777 Demolition have been contracted by Leslie Clark Construction Consultants to demolish a 4 storey office block with a roof top boiler room situated at City Road, Islington, London .
The Building has been scaffolded on all elevations due to its location.
The underground car park of the block is to remain as it still contains the main EDF Substation for the local area and will be propped by a Maybey System designed by our Structural Engineer to enable work by 360? machines.
This building is approx 300mm away from a newly opened development (Groveworld Limited) which means the first phase of the demolition needs to be done by hand , Top Down.
This is currently underway after negotiations with Groveworld Management to resolve any party wall issues. Once the first two bays ( 20m ) have been demolished a 360? machine will take over the next phase
Brokks are being used to hammer the floor slabs and ring beams cleared by Bobcats through an internal rubbish chute formed by a Brokk. All metal/wood is being separated at source to return back to Beddington Lane for recycling. Works are progressing to programme with approximately two weeks to complete the first phase of the Demolition works.

Demolition and dismantling specialist 777 Group has recently completed another major project in the centre of London using it two giant, 140 tonne Hitachi excavators. The latest undertaking centred on removing and recycling the subterranean foundations which once supported an uninspiring office block named Peggy Middleton House. With the building demolished several months previously, the removal of its foundations by 777 Group has ensured the site, which is currently at the centre of a £400m mixed-use regeneration scheme, will be available for developers on time and in good order.
Despite the immediate area having been earmarked for regeneration since the late 1990s, the recent extension of the Crossrail scheme to Woolwich has provided renewed impetus for a redevelopment scheme which includes the building a supermarket, 1000 flats and Greenwich council’s new civic offices on the site where Peggy Middleton House once stood. With the green light finally given to developers, 777 Group was given just eight weeks to break-out and recycle the building’s foundations; a task which proved more challenging that it sounds according to 777 Group’s Business Development Manager Daryl Pearce, “During our initial examination of the site it was difficult to tell the depth and strength of the building’s concrete foundations. These unknowns, coupled with a time restriction for completing the project meant we had to deploy our machines and operatives en-masse at the site. Suffice to say, it was a good job we have the in-house capability for such undertakings as the foundations have proved tougher and deeper than first thought”.
Instrumental in 777 Group’s ability to break-out, crush, back fill and compact the concrete foundations has been its extensive fleet of demolition machinery which includes two heavyweight Hitachi EX1200 excavators. Equipped with mass-excavation arms the EX1200s weigh in at nearly 140 tonnes each. Whilst one machine utilised a 7m3 MST bucket made from Hardox steel, the other hosted a brand new Atlas Copco hammer. Reputed to be the largest volume produced hammer in the world, the 10 tonne Atlas Copco HB10000 was used to good effect to break out over 50,000 m3 of reinforced concrete. The attachment housed a 24cm wide pin which can smash against concrete at a rate of 380 times a minute. According to Daryl the breaker’s performance played a vital role, “The combination of one of our EX1200s coupled with Atlas Copco HB10000 breaker really sped up the demolition process. With the Hitachi’s strong hydraulic power pack supporting the giant hammer the concrete came free at an impressive rate. Of course, having a second machine which can shift the giant slabs of broken concrete also helped things along”.
Although the two EX1200s have been the undisputed heavyweights of the project, 777 Group also managed to field an impressive array of other demolition equipment including numerous 20 tonne, 45 tonne and 70 tonnes excavators as well as a mobile crusher and dust suppression unit. The extensive array of equipment deployed ensured the basement was removed in an expeditious manner whilst minimising noise and dust.
The number of vehicle movements into and out of the site was significantly less than most operations of this size thanks to an on-site recycling programme. Approximately half of all the concrete arisings generated by the foundation demolition were crushed, backfilled and compacted in-situ in order to facilitate a level change for the base of the new building. “Had the requirement been to simply break out the foundations and take them off to our recycling facility the project would have been completed in an even shorter period of time. However, in order to reduce the number of journeys to and from the site and the amount of primary aggregate required for the new development, it was decided to recycle some 25,000m3 of concrete and reuse it on site. Utilising the Terex Pegson crusher and our heavyweight EX1200s the material could be crushed, backfilled and compacted in an expeditious manner”, said Daryl. Further to this, some 200 tonnes of rebar was extracted from the concrete foundations and removed from the site.
With the project completed on time and on budget, 777 Group’s ability to rapidly and safely remove irksome, stubborn structures such as the foundations of an uninspiring office have again been proven thus ensuring the long overdue redevelopment of central Greenwich starts without delay

London Borough of Sutton
The project consisted of a two stage contract. Stage 1 comprised preliminary works and demolition to foundation level. This stage included asbestos surveys, a controlled substance analysis, location of services and arranging disconnections, and the carrying out of building structural surveys and scaffold designs. Works were also undertaken in relation to the Wet Dock structure, carrying out all survey works both from dry standing and wet areas including below water surveys. All necessary licences and permissions were obtained to enable commencement of demolition works, and formal agreements were made with the local authority to progress works on a 24 hour basis. This was necessary due to the location and close proximity of structures in relation to occupied properties, businesses, public footpaths and major roads as well as the wet dock.
Structures occupying the site were constructed in various forms from traditional brick and block, solid 450mm stock brick construction, steel frame, concrete frame and cast in situ concrete silos to 65m. Works were completed with all buildings being demolished to slab level.
Stage 2 of the contract consisted of the removal of slabs, foundations, pile caps, pile probing and reduced bulk excavation, ground stabilisation and the installation of a designed piling mat. In all we removed some 18,240 tonnes of contaminated material from site. The company also remediated, screened and reused 9,500 tonnes of material excavated from below ground and 19,000 tonnes of crushed concrete from the building demolition which was processed to a certified 6f2 grading and used within the piling mat and ground stabilisation.

Our entire spectrum of services offered include:
Demolition, Asbestos Removal, Asbestos Surveys (Type 1, 2 & 3), Waste Management, Recycling, Diamond Drilling – UK’s Largest Super Long Reach Currently in Operation.
777 Group has been making the headlines for one of the most extensive fleet’s of machinery in the country including the two largest Long reach excavators in Europe today.
The 777 Group have a projected turnover for 2009 in excess of £25 Million
The company’s strategy is to maximise the recyclable materials from all waste streams eliminating potential transport costs and increasing its environmental gains
The increasing demand for replacement of out date and redundant tower blocks has enabled 777 to demonstrate our ability to dismantle tall structures safely and securely. Whether blocks are system built or structures cast insitu, the heights determine that different methods of dismantling are required. This is a complete package including the removal of any asbestos prior to the works and includes the design and installation of tower crane bases.
Before any crane lifting operations are commenced, site-specific studies are undertaken, detailing the exact planned position of the cranage, the types and weights of the elements to be lifted and the precise cutting operations to be effected.
The face of the demolition industry has changed beyond recognition in the last decade and we have always been at the forefront, driving these changes. As well as keeping ahead of new methods and machinery, constantly-evolving legislation and new codes of practice, we are always aware that the safety of both our operatives and the general public is all important.
Every one of our projects is planned with careful consideration to both the immediate environment, where we make great efforts to minimise disruption to nearby businesses and neighbourhoods, and the environment in general. We are genuinely proud of the fact that 98% of the materials removed from all of our sites are either re-used or recycled keeping the need to use costly and damaging land-fill to an absolute minimum.
As well as our ongoing investment in people, with one of the highest levels of staff training and certification in our industry, our investment in plant and machinery is second to none. Our latest acquisition, a second long reach machine with a standing height of 200ft, is the tallest in the world and unique to 777 Demolition
Working in this high-risk area for over 30 years, 777 Environmental recognises the absolute necessity for a safe and efficient service managed well beyond the standards of current legislation.
Asbestos surveys are carried out by our industry-leading and fully-qualified surveying team whilst removal is implemented by our ARCA-trained personnel. All work is constantly monitored both internally and in compliance with the ARCA Audit Accreditation Scheme. Any size of work can be carried out from a single domestic dwelling to massive multi-floor, multi million pound strip-outs. Soft strip and delicate demolition work, especially in highly sensitive situations such as operating hospitals and occupied offices, has become an area for which 777 Environmental has developed an enviable international reputation
777 Group continues to consolidate its position at the forefront of this critically important technology. Waste Management has rapidly become much more than just an industry.

777 Group has moved further into the tyre recycling market with the official launch of new technology capable of removing 100% of metal from used tyres.
This investment in tyre shredding technology at our Beddington recycling centre, has enabled us to increase our tyre reprocessing capability of 30 tonnes of tyres a day into rubber chippings.
The tyre shredding plant was officially launched On August 22nd 2008, with the technology allowing 777 to reprocess spent tyres from the public, councils and commercial businesses.
The technology, based on magnetic extraction, will allow 777 to increase its foothold in the tyre recycling market, making it capable of producing between 15 and 30 tonnes of 20 mm rubber chippings a day which are then sold onto third parties for use in artificial flooring surfaces or to be further processed.
Spent tyres from cars, trucks and larger plants are fed into a pre-shredder, which cuts tyres into 200ml strips before they are fed into the main shredder, which then further processes the tyres into 20ml strips. The strips are then passed under a magnet where metal wiring in the tyres is extracted.
The 777 Group offers a collection service for tyres, as well as accepting tyres delivered to the site from local businesses such as tyre fitters and garages. During commissioning stages 20,000 fly-tipped tyres were reprocessed on behalf of Croydon council. Any Enquires should be directed at Malcolm Beattie on 0208 689 6861
Ever changing regulations relating to the assessment for Business Rates make full decommissioning of buildings a viable option where the rental market turns down. It can be a costly process to leave an existing structure empty for landlords - We have seen a large demand for decommissioning especially in this uncertain economic climate.
Buildings can be zero rated where all of the non structural elements are removed and the building is therefore incapable of being put into beneficial use. 777 will undertake this decommissioning as part of our complete solution.
We specialise in Pre-Demolition site enabling works which render difficult sites suitable for development.
Site remediation and enabling works address the following areas:
1.Sites secured
2.Diversions set in place and existing services terminated;
3.Demolition work and removal of structures and hazardous materials;
4.Removal of below ground obstructions;
5.removal, recovery, recycling and disposal of contaminated soil via 777 Recycling; excavations and site-wide clearance and preparation works including haul roads, access ramps, berms and piling mats

History
777 Demolition & Haulage Co Ltd later to become the 777 group was established in 1964 by the late Mr John Pearce. Mr Michael Pearce joined 777 Demolition in 1967 with the grand purpose of expanding and developing the company whilst working alongside his father and founder. At that time 777 employed just four staff and operated only two standard demolition machines and two lorries. 777 have come a long way since then.
Demolition and Asbestos removal has always been our primary activities and over the years we have evolved dramatically into a company that is able to provide a full and comprehensive “One Stop Shop” service.

777 recently announced the acquisition of a new baby in the form of the latest addition to its family of robotic demolition machines, the diminutive Brokk 50. Originally designed to remove tiles from industrial settings, the 50 has found uses ranging from cleaning kilns for the ceramics and brick-making industries, to an essential role in the world's many nuclear power plants.
Now the Brokk 50 is proving invaluable to 777 Demolition as its ability to climb even the narrowest of staircases means this little wonder really can reach the places others cannot reach. But dispite its tiny footprint, the 50 manages to fight well above its weight and packs a mean punch.

777 GROUP SUCCESS STORY AT NHS LEWISHAM HOSPITAL DEMOLITION
The Lewisham Hospital Project was taken on as a Design and Build process, consisting of the demolition of 7 ward blocks located within the live hospital and included major asbestos surveying and removal.
There was extensive surveying and asbestos removal around live services as well as a re-insulation process, undertaken within confined spaces and extreme temperatures resulting in complex working methods and site set up being achieved.
The project also included duct strengthening works and civil engineering works - namely the installation of a new bespoke duct system, construction of a new 2 storey link and the construction of the major ground works, drainage and formation of car parks including associated M&E installations.
The project continues with the major refurbishment of a steel framed 3 storey building as a cladding and envelope lining package.
The Lewisham Hospital Design and Build package resulted in partnerships being formed with organisations such as Cyril Sweet PRC Engineering Ltd, Campbell Reith Consulting Engineers, Ansell and Bailey as well at DGT Structures.
The Gross Value of the Project currently stands at £5.6M
777 Group - 62m Super Long Reach hard at work
777 Demolition and Haulage Co Ltd were previously engaged by the London Borough of Barking & Dagenham to take the roll as Principle Contractor for the purpose of demolishing this 15 Storey high rise residential block, plus two 7 storey residential tower blocks and associated structures as part of London Borough of Barking and Dagenham's ongoing regeneration scheme.
Works include extensive asbestos surveying and removal, termination of all mains services including external lighting systems, the provision of hoarding to exclude third parties as well as providing temporary roads and vehicle access gates. The company provided a fully resourced team to execute the contract including structural, scaffolding and temporary works engineers, asbestos surveyors and removal staff, service engineers and demolition staff. 777 were a single sourced contractor for this project
777 Group continues leads the way drawing on an impressive range of high specification machinery in particular the specially-commissioned, highly-engineered giant 120 tonne Hitachi long-reach excavator with its 200 ft reach giving cost effective access to the most difficult of high rise structures, such as The Linton's.
777 now have acquired a second super long reach machine which can reach a massive height of over 200ft which really sets 777 firmly above other demolition companies.

777 goliath Hitachi's make small work of Silos
777 Group recently completed the safe demolition of six Silos at the Tate & Lyle site at Blackwall, London.
The high rise demolition works were rapidly completed with thanks to 777's two super long reach excavator both with a gigantic reach of over 60 metres.
Please see the dramatic photos featured on this story
The Atlas Copco HB10000 is reputed to be the world’s biggest and most powerful volume-manufactured hammer. It weighs 10t and is capable of an impact rate of 380 blows per minute. This is the first one in the UK.
777 Group won the contract for the final clearance of the 1.5 acre site in Woolwich, which was formerly occupied by Peggy Middleton House, a six-storey office block. The office building had already been demolished and removed, but the reinforced concrete foundations remained. With a tight time schedule for completion, sizeable financial penalties for overrunning, and the additional complication of working hour restrictions, speed and efficiency were called for.
To help meet the tight schedule, the company moved its two Hitachi EX1200 excavators to the site. One of these was equipped with a seven cubic metre MST bucket for clearing broken concrete. For breaking the concrete, however, which proved even tougher and deeper than was initially anticipated, the company decided that it needed to equip its second EX1200 with the HB10000 hydraulic hammer attachment.
The hammer broke out more than 50,000 cubic metres of reinforced concrete over a seven week period at the Woolwich site. It could have done the job even more quickly, the contractor said, had it not been decided to recycle 25,000 cubic metres of the concrete and reuse it on site to reduce the amount of primary aggregate needed for the new development.
“The HB10000, powered by the EX1200’s very capable hydraulic power pack, was able to break out the concrete at a truly impressive rate,” said 777 Group business development manager Daryl Pearce. “In fact, there’s little doubt that without it, we would have found it difficult to complete the contract on time. Our HB10000 was a significant investment, but it’s already proved its worth on this project, and it will undoubtedly be an invaluable asset for us on future contracts.”
The Atlas Copco HB10000 hydraulic breaker is suitable for use with carriers in the 85t to 140t class. It has 24-inch pin capable of up to 380 impacts per minute and operates at hydraulic pressures between 160 and 180 bar at flow rates of between 450 and 530 l/min. The breaker incorporates PowerAdept, a protection system that shuts it down if it receives excessive pressure from the carrier, and AutoControl, a monitoring system that allows it to automatically adapt its frequency and power output to match the operating conditions.
The undertaking centred on removing and recycling the subterranean foundations which once supported an uninspiring office block named Peggy Middleton House. With the building already demolished, the subsequent removal of its foundations by 777 Group has ensured that the site, which is currently at the centre of a £400m mixed-use regeneration scheme, will be available for developers on time and in good order.
Despite the immediate area having been earmarked for regeneration since the late 1990s, the recent extension of the Crossrail scheme to Woolwich has provided renewed impetus for the redevelopment scheme which will include building a supermarket, 1000 flats and Greenwich council’s new civic offices on the site where Peggy Middleton House once stood. With the green light finally given to developers, 777 Group was given just eight weeks to break-out and recycle the building’s foundations; a task which proved more challenging than it sounds according to 777 Group’s Business Development Manager Daryl Pearce, “During our initial examination of the site it was difficult to tell the depth and strength of the building’s concrete foundations. These unknowns, coupled with a time restriction for completing the project, meant we had to deploy our machines and operatives en-masse at the site. Suffice to say, it was a good job we have the in-house capability for such undertakings as the foundations have proved tougher and deeper than first thought”.
Instrumental in 777 Group’s ability to break-out, crush, back fill and compact the concrete foundations has been its extensive fleet of demolition machinery which includes two heavyweight Hitachi EX1200 excavators. Equipped with mass-excavation arms the EX1200s weigh in at nearly 140 tonnes each. Whilst one machine utilised a 7m3 bucket, the other hosted a brand new Atlas Copco hammer. Reputed to be the largest volume produced hammer in the world, the 10 tonne Atlas Copco HB10000 was used to good effect to break out over 50,000 m3 of reinforced concrete. The attachment housed a 24cm wide pin which can smash against concrete at a rate of 380 times a minute. According to Daryl, the breaker’s performance played a vital role, “The combination of one of our EX1200s coupled with Atlas Copco HB10000 breaker really sped up the demolition process. With the Hitachi’s strong hydraulic power pack supporting the giant hammer, the concrete came free at an impressive rate. Of course, having a second machine which can shift the giant slabs of broken concrete also helped things along”.
The number of vehicle movements in and out of the site was significantly less than most operations of this size thanks to an on-site recycling programme. Approximately half of all the concrete arisings generated by the foundation demolition were crushed, backfilled and compacted in-situ in order to facilitate a level change for the base of the new building. The remainder was dispatched to 777 Group’s recycling facility nearby. Some 200 tonnes of rebar was extracted from the concrete foundations and also removed from the site.
With the project completed on time and on budget, 777 Group’s ability to rapidly and safely remove irksome, stubborn structures such as the foundations of an uninspiring office have again been proven thus ensuring the long overdue redevelopment of central Greenwich starts without delay.

Demolition and Dismantling specialist 777 Group has recently deployed an innovative new protection system during the demolition of a seven storey office block in East London. The company successfully suspended a giant ‘protective blanket’ in between the condemned building and an area of ongoing construction work immediately adjacent to it.
The entire undertaking was something of a rarity as felling tall structures that are in close proximity to other buildings is usually the preserve of ‘top-down’ demolition techniques whereby the building is demolished floor by floor using small plant and labourers. This is often perceived as a slower, more expensive task but one that is normally necessary to prevent nearby buildings being damaged. The new technique found favour on the site in Greenwich where the blanket allowed the principle contractor to continue, unhampered by the adjacent demolition work, with the construction of Woolwich Central — a mixed use development that will include 1000 homes, a superstore and new council offices.
The innovative technique consisted of suspending a 28 metre long section of rubber matting in between the tower block and the ongoing construction project located immediately behind it with the assistance of a mobile crane. One of 777 Group’s Hitachi EX1200 ultra-high reach machines then demolished the structure in a conventional fashion with the rubber mat ensuring any debris that threatened to fall behind the tower block would not damage the adjacent construction work.
Produced specifically for the task in Greenwich by Lifting Gear UK Ltd, the giant mat is made from 7 metre wide sections of rubber conveyor belt which are clipped together. The clips allow the mat to be adjusted in length according to the task in hand. Complete with four half-tonne ground anchors located at the bottom of the mat, as well as its own block and tackle, the entire ensemble tips the scales at just over five tonnes. The task of suspending the entire blanket aloft during the project went to a mobile crane operated by Baldwins. Reaching into the London skyline, the crane was able to suspend the mat in a suitable position at the rear of the building.
With an estimated two hundred and fifty construction personnel working on the adjacent redevelopment, a series of safety mechanism were brought into play by 777 Group, crane hire firm Baldwins, and the company responsible for the nearby building work. With 777’s mammoth Hitachi EX1200 ultra high reach demo rig ripping down the office block piece by piece, an exclusion zone was established around the entire structure. Further to this, five banks men were positioned behind the building, just outside the exclusion zone to observe the undertaking. Equipped with walkie-talkies, the team could, if necessary, radio the Hitachi operative. Other considerations included wind speed and direction, both of which were monitored to prevent the suspended mat from tangling itself or impacting on the two structures.
Despite the use of the protective mat, the demolition of this 1960s tower block inevitably generated a degree of dust; a side effect that was mitigated by the use of a Dust Boss dust suppression unit. This pint-sized unit discharged a fine mist across the site ensuring clouds of dust did not affect business and homes nearby.
With just four weeks allocated by the principle contractor for 777 Group to surgically remove the council office building and the postal office immediately in front of it, the deployment of this ingenious protective blanket proved a godsend to those working on the demolition of the Greenwich’s past and those just a few metres away who are busy building its future.
