Demolition Costs – how are they calculated?

I have a large demolition project. Can you give me an idea of how work out how much it will cost? A question we quite often get asked at Downwell Demolition.

Demolition Costs

In many cases when we are asked for prices especially from people searching the Internet is to be as helpful as we can and give a budget price. This we usually do.

However, to give a truly accurate price there are a number of factors we have to consider. These are:

Building types

Buildings require different methods of demolition dependant on the way it is constructed so this, in turn, affects the cost to demolish.

Any structure can be demolished with the right method, experience, and qualified site team, therefore the variety of buildings and structures Downwell Demolition price is a pretty extensive list and include

  • Residential buildings
  • Office buildings
  • Schools
  • Warehouses
  • Factories
  • Industrial buildings
  • Tower Blocks
  • Chimneys
  • Bridges
  • Stadia

Demolition Methods

One project can contain a variety of structure types and require different methods such as top-down demolition, mechanical, and hand demolition.  The demolition method and location of the building is big determining factor on cost. For instance, if a building is in an area without any other buildings close by the demolition cost will be considerably lower than the same building in a confined area with other buildings close to it.

Size of the demolition site

The number of buildings, the size, and the structure type are all factors in the pricing of demolition works.

Materials

The cost of demolition will also be dependant on the materials the building is made from. Different materials have different costs associated with them. Hazardous materials that have to go to landfills are very expensive to dispose of. When pricing demolition we need to have surveys to establish the amount of hazardous materials present for their removal and disposal.

Where possible a demolition company will recycle or reuse up to 96% of materials from the site. If materials remain on-site there is a cost for crushing or screening but there are massive savings on transportation and disposal.

Certain metals have excellent scrap value and these costs can often be offset against the cost of the demolition. These are referred to as credits.

Restrictions and locations

The location of a project has a big impact on demolition costs. An inner-city location will usually have tight access to a site, as well as require protection for nearby buildings and the general public. It is most likely that in a built-up area, that scaffolding along pedestrian routes and liaison with the local community is needed.

Downwell is experienced in working on ‘live’ sites requiring special precautions and access routes. We can work adjacent to schools and railway lines. The protection of existing services, substations, and remaining buildings can also arise on projects.  All these are taken into consideration when costing a demolition project.

Bill of quantities

The pricing of demolition work is also based on years of experience and quite often we are asked to break down costs to the removal of windows per item but generally, we prefer to give an inclusive for the overall demolition. Any hazardous waste, disconnection of services etc is always shown separately.
