DEMOLITION
PROJECTS

Project: Transfer Tower Demolition

​

Scope: Temporary Works, Strip Out, Dismantling and Demolition

​

Duration: 5 Weeks

Evolution Demolition were tasked with the demolition of the existing grain transfer tower.

 

The works required the temporary propping of the existing adjoining transfer gantry and the subsequent demolition of the tower in readiness for the erection of the new tower.

 

Given the close proximity of the structure to adjacent buildings and other ongoing works as well as the challenging weather conditions on the river front, the project had to undergo extensive planning and preparation.

 

Fire and dust explosions were a risk that had to be managed during the works as well as the extensive temporary works. To enable demolition, the works had to be planned to accommodate the construction of the new structure. The temporary works were monitored for a prolonged period during construction.
 

Scope of work included:

​

  • Design, supply & erection of temporary works including piled foundations

  • Erection of temporary tower to support cantilever section of the attached gantry

  • Preparation of the structure for demolition

  • Demolition of the structure

  • Removal of the foundations

 

​

Project: Agar Grove

​

Scope: Demolition

​

Duration: 19 Weeks

​

Evolution were tasked with the asbestos removal, demolition and enabling works at the Agar Grove estate.

 

The works required logistical planning due to the large amount of asbestos present in the buildings and the tight program of the piling.

 

Demolition works were undertaken using both high reach demolition plant and standard demolition excavators.
 

All material was crushed for re-use on site. As part of the enabling works, a reduced level dig was undertaken and contaminated spoils were removed from the site.

 

Evolution also undertook the removal of a large number of trees to make way for the new development. The trees are due to be replaced at a later date.

​

​

Project: Friern Park

​

Scope: Strip Out, Demolition and Crushing

​

Duration: 6 Weeks

Evolution Demolition were tasked with the demolition of the structure in Friern Park.

 

Demolition preparation works involved the strip out, removal of asbestos and fly tipped rubbish, waste removal and full scaffold.

 

Demolition was undertaken using high reach demolition machinery and dust suppression machinery.

​

All waste was segregated on site for removal and recycling with suitable arisings crushed and left on site for future use.

​

The works also involved significant knotweed removal and protection measures.

 

​

Project: Folkstone Beach Huts

​

Scope: Demolition and Waste Removal

​

Duration: 12 Weeks

Evolution Demolition were tasked with the demolition of multiple concrete panel construction beach huts on the South coast.

 

The demolition itself was simple, logistics and access were not.

 

With all routes to the structures along the pedestrian sea wall and the works open to the elements, the works had different challenges. The beach huts were spread over approximately 4 miles of coast line and with the sea wall and beach area remaining open for the duration of the works. Delivery of plant and materials and the removal of waste had to be carefully planned.

​

The works also included significant sea wall strengthening and saw cutting of additional drainage run off locations.

​

Project: Avenue Heights, Highgate

​

Scope: Demolition, Asbestos Removal, Hoarding, Reduced Level Excavation. 

​

Duration: 12 Weeks

Evolution Demolition were contracted by Morgan Properties as PC by competitive tendering to undertake demolition, hoarding and reduce level excavation of Avenue Heights in Highgate to make way for a new high-end residential development.

​

The tower block and car park were occupied throughout the demolition phase meaning Evolution’s management went far beyond the works package with constant interface with residents and visitors meaning logistical plans in and around the site required updating and managing regularly.
 

Scope of work as follows:
• Design, Supply & Erection of site hoarding
• Vehicular & Pedestrian traffic management
• Controlled dismantling, demolition of structure using 

   conventional and robotic demolition techniques c/w full 

   environmental monitoring.
• Asbestos Removal
• Land Remediation
• Earthworks
 

Asbestos material buried sub-surface and within the ducting under the slab (not reported within site demolition Asbestos report) was discovered by Evolution during excavation. The team then undertook an operation of ground remediation, safely removing all buried asbestos material from the site. There were also a number of un-surveyed services that entered the tower block through the ground floor slab which Evolution were required to locate and re-route to avoid the risk of damage.

Project: Esplanade Public House, Southend on sea

​

Scope: Demolition, Land Remediation, Temporary Works

​

Duration: 26 Weeks

​

Evolution Demolition Services were contracted in by Beyond the Box Developments as PC to undertake demolition and ground clearance of the Esplanade Public House on Southend-on-Sea seafront, to make way for a new high-end residential development.

The building was actually set fire prior to Evolution starting on site.  We were then called in as an emergency to make the fire-damaged steel frame structure safe once the Fire Services had finished their work.

 

Evolution Demolition's scope of work thereafter was as follows:​​

​

  • Controlled dismantling and demolition of structures using conventional and robotic demolition techniques c/w full
    environmental monitoring

  • Temporary works to secure retaining wall (the building is at the foot of a steep cliff that has suffered landslides in the last twenty years towards the seafront)

  • Concrete crushing and construction of piling mat with crushed material

  • Vehicular & pedestrian traffic management

  • Design, supply & erection of site hoarding

  • Asbestos removal

  • Land remediation

 

Asbestos material buried sub-surface was discovered by Evolution prior to any excavation taking place, Evolution then undertook an operation of ground remediation, safely removing all buried asbestos material from the site. Evolution Demolition Services handed the site over to the new build contractor fully prepared, level, asbestos free, and stable, complete with prepared pile mats and a tower crane base (from recycled clean crushed concrete) ready for new build activities on time and within budget.

Project: The Lawns 

​

Scope: Demolition, Asbestos Removal

​

Duration: 15 Weeks

​

Evolution were tasked with the demolition, asbestos removal, site setup, hoardings and client mobilisation of the Lawns project. The Lawns was a seven story building in the centre of Stoke Newington with heavy passing traffic and a school in close proximity, with a number of pinch points, parts of the demolition were undertaken out of hours and with full road closures.
 

Both standard and high reach demolition specification excavators were employed to reduce the building down to ground level. Foundations were excavated down to 7m and broken out and removed. Pile mats were excavated and constructed and a surplus of over 6000m2 of crushed material was removed off-site.

Evolution provided asbestos removal, demolition, and working platform construction. In addition, extensive utility and service investigations were conducted to facilitate demolition work. As a result of various construction phases and varying main contractors, the condition of existing utilities was unknown.

 

We were contracted to perform detailed exploratory works and provide the client with survey information to enable further design and re-routing of existing utilities to enable demolition.
 

The project is adjacent to a busy school and located within an estate that has previously undergone high-profile construction. In order to mitigate the noise and dust generated by demolition and construction works, we utilized cutting-edge 24hr sound and dust monitoring systems. All demolition materials were salvaged for re-use on site or in the surrounding area using high reach excavators.  

Mardyke Estate 

​

Scope: Demolition, Asbestos Removal

​

Duration: 10 Weeks

​

It was Evolution Enabling's task to undertake specialist demolition and cutting works to an existing 24 storey building in Croydon High St. The project was scheduled to be completed within a tight time frame with demolition works taking place in and around other trades.
 

Our onsite management had undertaken robotic demolition and concrete cutting to parts of the structure with trades works in the vicinity. Our on-site management and programming of works were crucial to ensuring works are carried out safely with the minimum of disruption to other trades whilst still achieving the dates required by the MC. Noise, dust and vibration were closely monitored to ensure safe working conditions.

 

We also undertook the removal of concrete cladding panels to the exterior of the building on the 23rd floor.

 

The removal of the panels was an extremely high-risk operation with working methods devised, adapted and monitored by our onsite management team. To date, we have  drilled through over 1000lm of concrete for the installation of new services within the building.

Project: Leon House

​

Scope: Demolition, Structural Alterations

​

Duration: 30 Weeks

Evolution undertook the demolition of the network rail logistic yard adjacent to the main rail line.

 

Works involved separation of the structure from adjacent buildings, soft strip and recycling of all waste and arisings.

​

All works were completed on program with the site back open in time for follow on works to start.

​

With the adjacent building remaining occupied for the duration of the works, the adjacent rail line and asbestos present on site the works required careful planning and management.

Project: Chestnut Rail Depot

​

Scope: Demolition, Structural Alterations

​

Duration: 5 Weeks

Various sites across Kent required demolition to enable construction of residential dwellings.

 

Evolution teams were despatched to undertake the demolition, site clearance and securing of the works areas. The teams worked across multiple sites with supervision and management in place to manage the various different site and differing stages of works.

​

Due to the nature of the site significant management of local residence and boundary lines was required.

Kent Garage Sites

​

Scope: Demolition, Structural Alterations

​

Duration: 10 Weeks

We were employed to undertake the demolition and structural alteration of 3 listed buildings to the St Luke’s development in Muswell Hill.

 

Our works included:

 

  • Full demolition of elements of the structures conception, design and implementation of a temporary works scheme

  • Full strip out and removal of all timber elements

  • Excavation and formation of 3 new basements

  • Conception, design and implementation of permanent structural steel elements

  • The construction of all new timber floors

  • All buildings work to include new internal brickworks and new works to the retained listed façade

 

The project was extremely complex due to the fact all 3 buildings were listed. The buildings also sat at the entrance point to a major £56m new development posing significant logistical issues.

 

Due to the complexity of the works we were employed to provide the client with a blank canvas and sound structure to fit out on completion of our works. We undertook the design and management of all temporary façade retention and permanent structural elements.


Our on-site management team had to adapt to the ever-changing scope of works found within complex refurbishment works. Our management team liaised with various other subcontractors on-site and worked closely with the main contractor to ensure our work and the logistic constraints on site worked in conjunction with the main development, and the project finished on time and on budget. All builders' work included restoration of arch detail brickwork to match 200-year-old designs. 

Project: St Lukes 

​

Scope: Demolition, Structural Alterations

​

Duration: 78 Weeks

Evolution were contracted to undertake the partial demolition and ‘cut and carve’ works to Vic Johnson House. The scope involved complex demolition of the wings to either end of the building and an independent dwelling. The complexity was born out of the live, inhabited status of the remaining building at the centre of the works. Evolution’s diamond drilling and cutting division assisted with the separation cuts and robotic Brokk demolition of the concrete staircases and interfaces. All demolition arisings were crushed on site for use in the pile mat.

 

Evolution also undertook the licenced and non-licenced asbestos works involved in the project. The demolition moved onto the structural alterations phase. The building required many new structural openings; they were propped with designed temporary work solutions, cut out and lintels installed. Other required builders work was carried out along with installation of new permanent steels.
