Whether it be an industrial warehouse or a high-rise block of flats, each demolition project is totally unique. Demolishing a building certainly requires a lot of careful consideration – the way in which a structure is demolished and the machinery that is used is based on several varying factors including the materials used in the construction, its size, the surrounding environment and the location of the structure.
Planning the correct Methodology and Plant and Equipment to use is the key to a successful project.
At Hughes and Salvidge we carry out demolition work on a wide variety of building structures across several sectors, ranging from chemical plants and airports to tower blocks and schools. We ensure that every possible factor has been considered so that the correct method of demolition and machinery is chosen for the job in hand.
Low Level Demolitions
For houses and other small buildings that are only one or two storeys high, the demolition process is reasonably straightforward. Small buildings can be demolished by hand, although this is obviously not the most time-effective option. Alternatively, small buildings can be pulled down mechanically with the use of specifically designed demolition excavators.
Hydraulic excavators are essentially tracked plant that demolish small buildings. We operate 1 tonne to 100 tonne excavators and the range in both size and function allows the excavators to work on a variety of tasks within various project areas. At Hughes and Salvidge we use a variety of different attachments to suit the job in question. Another key benefit to using hydraulic excavators for demolition is their ability to perform a number of different tasks with the use of different attachments such as rotational grapples, pulverisers, steel shears and impact breakers.
High Level Demolitions
The use of Hi- Reach excavators is a relatively modern method of demolition, and involves the use of a machine with a particularly large boom arm. Designed to reach the upper storeys of multi-storey buildings, these excavators have, in some instances, taken away the need for scaffold and demolishing buildings using mini excavators. Excavators are equipped with different tools such as pulverisers, shears, breakers, and selector grab attachments – each attachment has a function in the work carried out by Hughes and Salvidge. Hi-Reach excavators can be used on various building structures such as steel, concrete and mixed material.
Hughes and Salvidge have a wide range of machinery other than excavators that are used on demolition projects of various sizes, for a number of different functions. These include:
Dust Boss Machines: Used for dust suppression during the demolition process, Dust Boss machines minimise dust pollution in the immediate environment by spraying a fine mist of water onto the demolition.
Bobcat Skidsteers: These are used alongside operatives during the initial soft stripping of buildings before structural demolition.
Low Loaders: Transporting large excavators and crushers from site to site.
Concrete Crushers: Our sister company, K&B Crushers, operate 10 mobile concrete crushers – the largest fleet in the UK. This plant is used for producing recycled aggregate from demolition brick and concrete arisings. Recyclability on the majority of Hughes and Salvidge projects is above 95%.
HIAB Trucks: These are used to deliver and remove small plant and machinery or other tools and equipment to and from the site.
Roll On / Roll Off Wagons: Delivering and collecting various types of waste arising from the works. Generally operated by our sister company Aasvogel.
Wheeled Tippers: These are used to remove either uncrushed or crushed masonry/brickwork and concrete.
Explosive methods may be chosen when demolishing large structures, bridges and chimney stacks, and is a very quick and effective method of demolition. Using this technique, the main supports of the building are fixed with explosives. In these cases, Hughes and Salvidge use a specialist and certified contractor to carry out the weakening and explosion of the structure and assist in all logistics and setting up of explosive zones.
Once the structures are felled and deemed safe to return to site, plant and machinery go about processing arising materials.
Explosive demolition takes planning and co-operation of all parties and stakeholders, including Councils, Police and other Emergency Services.
As an audited member of the National Federation of Demolition Contractors, Hughes and Salvidge can guarantee a well-managed and safe demolition project. If you would like to find out more about our demolition services, or any of our machinery, please contact us for more information.
