Residential Deconstruction

What Is It?

Deconstructing a building allows you to take it apart systematically, so you can salvage reusable building materials and recycle materials that can’t be reused. Salvaging reusable building materials reduces the amount of construction waste sent to landfills and reduces the demand on natural resources.

If you are removing housing, deconstruction may allow you to begin the process before we have issued you a new building permit for your site. (A new building permit is usually required before you can demolish housing; see Demolition of Housing for other rules that may apply).

To qualify for a residential deconstruction permit, you must:

• Reuse a minimum of 20 percent of the building materials, by weight and excluding asphalt, brick, and concrete
• Recycle or reuse a minimum of 50 percent of the building materials, by weight and excluding asphalt, brick, and concrete
• Recycle or reuse 100 percent of asphalt, brick, and concrete
• Submit a Waste Diversion Plan with your permit application and plans (as described in Directors Rule 4-2009, Demolition Permits With Waste Diversion Plan)
• Submit a Waste Diversion Report that identifies the actual rates of salvaged and recycled materials when deconstruction is complete

If you want to deconstruct a building in an environmentally critical area, such as a wetland or a steep slope, there are different restrictions you must follow.

How Much Does It Cost?

The fee for a deconstruction permit is the base fee, per the Fee Subtitle, plus any additional review fees. You may need to pay additional fees if the disturbed ground area exceeds 750 square feet or if your project needs deep cuts in the soil or shoring (supports to prevent collapse).

You pay your fees when you submit your plans. You pay the remaining fees when you pick up your permit.

How Long Does It Take?

Our goal for completing a review of your residential deconstruction (demolition) permit application is 2 days.

We will review your plans to make sure they meet our code standards. Your inspector will review building code requirements on site during your inspections.

About Demolition Insurance?

Demolition insurance is a type of insurance protection that makes it possible to absorb the costs of tearing down a building that has been damaged beyond the point of repair. Sometimes referred to as a named perils of insurance policy, the coverage aids in razing structures that have been damaged by fire, wind or some other event and are no longer safe for use. Often, this type of insurance works hand in hand with personal and commercial property insurance to not only level the damaged building, but also to remove the debris from the building site.

One of the main benefits of demolition insurance is that it provides the resources necessary to remove a damaged structure from a piece of property. Most insurance contracts with this type of coverage call for inspection of the structure before the final razing is undertaken. Once both local authorities and the insurance company agree the damaged building is beyond repair and poses a threat to public safety, a crew is engaged and the building is leveled.

Some types of demolition insurance not only provide resources for tearing down structures damaged in a disaster, but also cover the costs of having the debris from the building removed from the property. In some cases, the owner’s property insurance will cover this aspect of the project, even though that insurance does not cover demolition. Should the property insurance cover the charges for hauling away the debris, that policy is considered the primary coverage for that portion of the project, with the debris removal provisions in the demolition insurance classified as secondary. This means that any costs not covered by the primary coverage may be further offset by the coverage in the secondary policy.

As with all types of insurance, any claims submitted on a demolition insurance policy must meet the qualifications named within the terms of the policy itself. For example, if a building is partially destroyed by fire, the insurance provider may not honor the claim until the property is inspected and the building is considered a total loss. Some providers will also require that local authorities examine the property and declare it unsafe for use and beyond the potential for repair as a means of bring the building back into compliance with local safety codes. For this reason, understanding local building codes and the exact provisions of the policy before securing demolition insurance is extremely important. Protect your property insurance demolition.

Guide House Demolition

Environmental Impact

In a rural area it is likely that a wildlife survey undertaken by an ecological consultant will be requested by the local planning authority, as part of the pre-application process for a replacement dwelling.

If evidence of endangered species is detected (typically bats, barn owls, badgers and great crested newts), a further report will be required from a specialist before work can proceed, and this will recommend the time of year that demolition work can take place and the mitigation measures required, such as providing alternative habitats.

Cost

A large part of the cost of demolition is landfill and haulage, so costs can be reduced if there is scope to reuse or dispose of non-toxic waste on site — such as clean hardcore for drives, paths, terraces and soakaways.

The time taken for demolition work depends on scale and complexity but will typically take four to eight days. If the building is a semi or terraced house, the adjoining buildings will require support following demolition, adding to the cost.

If there is specialist work required, such as removing asbestos (often found in the form of cladding, roofing and rainwater goods) this can complicate issues. There are strict rules on the removal and handling of asbestos, and it can be best to get a report and quote from a specialist contractor.

Demolition Method

The following order of works is typical for demolishing a house:

• Cut off and cap all services such as main water and sewer connection, electricity, gas and telephone.
• Erect site fencing and protect the site; erect scaffold if required.
• Hazardous material (i.e. asbestos) removed under licence or by specialists if necessary.
• Soft strip all loose items, kitchen, sanitaryware, and remove all cabling, lighting, plumbing, radiators etc.
• Remove all doors, windows frames, linings, internal/external timber mouldings etc.
• Strip roof and lead flashings.
• Remove structural timbers, joists and trusses.
• Demolish walls, salvaging bricks for example. Unwanted materials can be removed for crushing.
• Break up remainder and grub up foundations and redundant drains.
• Planning Permission

Working With Neighbours

If you are demolishing a property other than a detached house, the likelihood is that adjoining neighbouring properties enjoy a right of support — a special type of easement recognised and protected in law.

When you undertake demolition works, you have a duty to support the remaining portions of the building and to ensure the new building continues to do so.

The same right of support applies if you are excavating ground adjacent to a neighbour, for instance for foundations or a new basement.

5 Steps to save money on your project demolition

1. Look in your local phone book- There is a section of the phone book that can direct you to local recyclers in you area by types of material to be recycled. Most materials that you will be recyling will be a charge to you, so make sure you find the best deal per ton.
2. Put an ad on your local classifieds (like craigslist)- We offered everything from roofing tiles, windows, doors, broken concrete and more online.
3. Hold a yard sale- You will be able to reach buyers that aren't as computer savy and have ready cash in hand.
   
4. Pull out all your electrical wire and copper piping- A local salvage yard will pay you for these items. Just make sure to seperate the materials before you go.  For everything else you need to dump, just call your local garbage company to arrange a garbage bin to be delivered to your dumpsite. It helps make clean up easier, plus it will motivate you to fill it up!
5. Once you get your house down to a shell, consider hiring a professional grader to tear down and recyle the concrete and lumber from your project.

We show as a building explodes to demolish

We show as a building explodes to demolish

DCI Demolition  we show as a building explodes to demolish. You can demolish a stone wall with a sledgehammer, and it's fairly easy to level a five-story building using excavators and wrecking balls. But when you need to bring down a massive structure, say a 20-story skyscraper, you have to haul out the big guns. Explosive demolition is the preferred method for safely and efficiently demolishing larger structures. When a building is surrounded by other buildings, it may be necessary to "implode"the building, that is, make it collapse down into its footprint.

In this article, we'll find out how demolition crews plan and execute these spectacular implosions. The violent blasts and billowing dust clouds may look chaotic, but a building implosion is actually one of the most precisely planned, delicately balanced engineering feats you'll ever see.

The Bigger They Come, the Harder They Fall

The basic idea of explosive demolition is quite simple: If you remove the support structure of a building at a certain point, the section of the building above that point will fall down on the part of the building below that point. If this upper section is heavy enough, it will collide with the lower part with sufficient force to cause significant damage. The explosives are just the trigger for the demolition. It's gravity that brings the building down.

Demolition blasters loadexplosives on several different levels of the building so that the building structure falls down on itself at multiple points. When everything is planned and executed correctly, the total damage of the explosives and falling building material is sufficient to collapse the structure entirely, so cleanup crews are left with only a pile of rubble.

In order to demolish a building safely, blasters must map out each element of the implosion ahead of time. The first step is to examine architectural blueprints of the building, if they can be located, to determine how the building is put together. Next, the blaster crew tours the building (several times), jotting down notes about the support structure on each floor. Once they have gathered all the raw data they need, the blasters hammer out a plan of attack. Drawing from past experiences with similar buildings, they decide what explosives to use, where to position them in the building and how to time their detonations. In some cases, the blasters may develop 3-D computer models of the structure so they can test out their plan ahead of time in a virtual world.

The main challenge in bringing a building down is controlling which way it falls. Ideally, a blasting crew will be able to tumble the building over on one side, into a parking lot or other open area. This sort of blast is the easiest to execute, and it is generally the safest way to go. Tipping a building over is something like felling a tree. To topple the building to the north, the blasters detonate explosives on the north side of the building first, in the same way you would chop into a tree from the north side if you wanted it to fall in that direction. Blasters may also secure steel cables to support columns in the building, so that they are pulled a certain way as they crumble.

Sometimes, though, a building is surrounded by structures that must be preserved. In this case, the blasters proceed with a true implosion, demolishing the building so that it collapses straight down into its own footprint (the total area at the base of the building). This feat requires such skill that only a handful of demolition companies in the world will attempt it.

Blasters approach each project a little differently, but the basic idea is to think of the building as a collection of separate towers. The blasters set the explosives so that each "tower" falls toward the center of the building, in roughly the same way that they would set the explosives to topple a single structure to the side. When the explosives are detonated in the right order, the toppling towers crash against each other, and all of the rubble collects at the center of the building. Another option is to detonate the columns at the center of the building before the other columns so that the building's sides fall inward.

Generally speaking, blasters will explode the major support columns on the lower floors first and then a few upper stories. In a 20-story building, for example, the blasters might blow the columns on the first and second floor, as well as the 12th and 15th floors. In most cases, blowing the support structures on the lower floors is sufficient for collapsing the building, but loading columns on upper floors helps break the building material into smaller pieces as it falls. This makes for easier cleanup following the blast.According to Brent Blanchard, an implosion expert with the demolition consulting firm Protec Documentation Services, virtually every building in the world is unique. And for any given building, there are any number of ways a blasting crew might bring it down. Blanchard notes the demolition of the Hayes Homes, a 10-building housing project in Newark, New Jersey, which was demolished in three separate phases over the course of three years. "A different blasting firm performed each phase," Blanchard says, "and although all of the buildings were identical, each blaster chose a slightly different type of explosive and loaded varying numbers of support columns. They even brought the buildings down in different mathematical sequences, with varying amounts of time factored in between each building's collapse."

Once the blasters have figured out how to set up an implosion, it's time to prepare the building. In the next section, we'll find out what's involved in pre-detonation prepping and see how blasters rig the explosives for a precisely timed demolition.

Principal Demolition Methods

Principal Demolition Methods

Demolition methods can vary depending on the area where it will be held on, the building material, the purpose of the demolition and the way that debris is going to be disposed. In the article we present with some of the most used methods for demolition of structures.

Demolition Method: Implosion

Implosion is a violent bursting inward that allows the sequential elimination of structure supports.

Enough explosives are used to eliminate the critical vertical structural supports. Theplacement of the charges and the sequential detonation timing is if vital importance, allowing the collapse of the building induced by the weight of the structure. Implosion demolition methods are used in urban areas and often involve large structures.

For a successful demolition a complete set of structural blueprints must be analyzed to study the main component of such building. Also another important step is to have theblaster crew complete an assessment of the structure of the buildings to identify other areas that need to be blasted, in addition to the ones identify on the blueprints. As a final step is important to decide the type of explosives to use, where to position them in the building and how to time their detonations.

High Reach Arm

High reach arm is another traditional method of demolition. The threshold for defining a high reach demolition is when it reaches a height of more than 20 meters.

This method is usually formed by a base machine (excavator, tank, engine, counterweights), a demolition arm consisting of three sections or by a telescopic boom and a primary tool attached to the base machine (crushers, shears, hammers).

High reach demolition machines can be equipped with different tools to make them suitable for executing demolitions of structures. This method is used on reinforced concrete, masonry, steel and mixed material structures. The machines used in this type of demolition are not the only machines used in the process; there must be additional components used for secondary operations such as crunching of material. Several factors control the method like the height of the structure being demolished, site conditions and structure shape.

Demolition Method: Crane & Ball

One of the oldest and most commonly used methods for building demolition, the ball and crane use a wrecking ball weighing up to 13,500 pounds to demolish concrete and masonry structures. During the process, the ball is either dropped onto or swung into the structure that is to be demolished. The ball and crane, however, is unsuitable for all demolition applications. Some limitations:

• Additional work removing rebar in concrete structures is needed.
• Only highly skilled and experienced crane operators should be used on ball and crane demolition
• Smoothness in controlling the swing of the ball is CRITICAL since missing the target may tip or overload the crane.
• The size of the building that can be demolished with this method is limited by crane size and working room, including proximity to power lines.
• This form of demolition creates a great deal of dust, vibrations and noise.

Demolition Method: Selective Demolition

Also known as strip-out, this process is very popular right now. As recycling andsalvaging of material are very attractive to builders during these days, allowing them to re-use material or recycle it. Selective interior / exterior demolition or recycle of wood, brick, metals and concrete are all recycled for future use in new structures blending the old with the new. This demolition process is not limited to removal of interior equipment, walls, floor, ceilings and exterior components. The main purpose of this method is to recover the maximum amount of primarily reusable and secondary recyclable material in a safe and cost-effective procedure. Although it is a labor intensive process and can be very difficult to achieve in a timely and economical manner for light framed buildings.
