|Project:||Demolition & Site Clearance of Sherwood E-Act Academy|
|Date:||Programme: 20 weeks|
Situated in a busy residential and commercial environment, Ron Hull Demolition Ltd were awarded the works following a competitive tender, based on competency and quality after demonstrating robust methods, policies and procedures.
The site was on multi levels with the land sloping away in a northerly direction. The buildings were of various construction and positioned at various levels across the site. The buildings were single or 2-storey construction and a combination of either clasp and block and beam, brick structures or steel portal framed structures.
Direction of demolition was carefully planned to not encroach within the identified trees for retaining footprint, care was taken to ensure that when demolishing the elevations adjacent to the trees the debris was pulled into the footprint of the building.
Ron Hull Demolition Ltd’s dedicated liaison team worked closely with local residents, businesses and all concerned at the Academy ensuring Client satisfaction at all times. Ron Hull Demolition Ltd believe that engaging with people from the beginning, understanding concerns within the local area is crucial to achieving a successful completed project.
Phase One – Various Buildings & Sports Hall
Comprised of clasp buildings which were prefabricated light gauge steel framed structure with concrete cladding external walls and a sports hall.
Commencing demolition from the east elevation, the excavator with shear attachment punctured into the end elevation removing the gable end side metal sheeting, these were placed to one side ensuring segregation form other waste streams. Once the internal steel framed structure had been exposed, the shear punctured and cut at the centre of the apex of the roof on the diagonal roof steel beams cutting 50-75% of the beam.
Phase Two – Boiler, Plant Rooms & Gymnasium
Comprised of single storey brick utility buildings (boiler rooms) and low-level assembly hall and gymnasium. The building extended to a two-storey classroom complex running along the south elevation of the site.
The first stage of the demolition works was to demolish the low-level boilers buildings and gymnasium.
Once all the boiler structure had been removed the area was cleared of demolition arising prior to bringing the chimney stack down removing the brick sections. The demolition works were carried out in reverse order to the building’s original construction.
Phase Three – Single Storey Annex
The machine progressed through the structure working between columns. Once the machine has got to its maximum reach potential works shall start on the adjacent area. To maintain the stability of the structure the excavator shall demolish the building evenly in an east to west direction. The direction of demolition will be to commence from the east side of the structure working through the upper floors then removing the first-floor area before clearing the ground floor. Working from column to column along the length of the structure, the arisings were cleared from the ground area and separated.
A 2-storey clasp construction structure building comprising of steel and concrete internal support structures with external concrete slabs. The excavator machine commenced demolition from the south west elevation of the building, commencing with the removal of the external concrete slabs to expose the inner structure. Progressively working through the structure in a northerly direction, working between the main column legs, ensuring structural stability to the remaining structure.
A complex 2-storey clasp construction structure building comprising of steel and concrete internal support structures with external concrete slabs. The building was built with a sequential number of annex structures attached with the main support beams running from north to south. The excavator machine commenced demolition from the south east corner of the building. Progressively working through the structure in a northerly direction, working between the main column legs, ensuring structural stability to the remaining structure. Once one annex structure had been demolished the machine tracked back and repeated the process working from the south elevation to the north.
