TEMP WORKS &
STRUCTURAL STEEL PROJECTS
Client: Morgan Properties
Project: Avenue Heights, Highgate
Scope: Demolition, Asbestos Removal, Hoarding, reduced level excavation.
Duration: 12 weeks
Evolution Demolition was 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, so Evolution 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 reroute to avoid the risk of damage.
Client: Beyond the box developments
Project: Esplanade Public House, Southend on sea
Scope: Demolition, land remediation, temporary works
Duration: 26 Weeks
Evolution Enabling Services was contracted in by Beyond the Box Developments as PC by competitive tendering 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 Enabling 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 (Not reported within site Demolition Asbestos report) was discovered by Evolution prior to any excavation taking place so Evolution then undertook an operation of Ground remediation, safely removing all buried Asbestos Material from the site. Evolution Enabling 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 Enabling were tasked with the Demolition, asbestos removal, site setup, hoardings and client mobilisation of the Lawns project. The lawns were a Six/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 long 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. Therefore, we were contracted to perform detailed exploratory works and provide the client with survey information to enable further design and rerouting 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.

Project: Mardyke estate
Scope: Demolition, Asbestos removal
Duration: 10 Weeks
Client: Bouygues UK
Project: Leon House
Scope: Demolition, Structural Alterations
Duration: 30 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 have been 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 are closely monitored to ensure safe working conditions. We have also undertaken 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 also drilled through over 1000lm of concrete for the installation of new services within the building.

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 follow on the program of the piling. Demolition works were undertaken using both high reach demolition plant and standard demolition excavators.
All material was crushed from 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: St Lukes
Scope: Demolition, Structural Alterations
Duration: 78 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 facade
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, therefore, 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: Vic Johnson House
Scope: Demolition, Structural Alterations
Duration: 5 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-licensed 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 and were cut out and lintels installed. Other required builders work was carried out along with installation of new permanent steels.
