We at DCI Demolition explain all about. Residential Deconstruction

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.

What is Excavation?

The excavation is the process of moving earth, rock or other materials with proper tools and equipment, explosives were also used in some occasions. The excavation has important applications including exploration, environmental restoration, mining, construction and demolition. Including the construction is one of the most common applications for excavation.

In DCI Demolition, how does the process?

Before the excavation process can begin, the site should be carefully examined to ensure that the natural habitat and artifacts that surround it are persevered in any excavation. Then they plan for the size and depth of the site and make excavation company draws pictures of them to clearly mark the boundaries of the excavation site. Once you have taken these two important steps, excavation work can begin. All the excavation process includes:

establishing benchmarks corner
the topography of the ground and upper levels
excavation depth approved
dress the loose soil
doing to cut level
the construction of wells and trenches dehydration interconnection
making the building limits
construction of levees and drains
When building excavation used?

Who conducts the digging?

Excavation construction requires experience, skill and attention to detail. In DCI Demolition  we deal with large structures and cremos the basis for the entire project.

What is Excavating Contractor?

In the world of construction, excavation contractors do much more than haul dirt around; their responsibilities include site preparation, grading, trenching and many other soil-related tasks. And, yes, they do operate some very large pieces of heavy equipment.

Site Preparation

In a typical residential construction project, the excavation contractor shows up after the surveying crew determines the house and lot boundaries. The contractor removes the soil to the depth required for the new foundation and ensures that the soil is firm through compaction tests and compaction with equipment, if necessary. The dig requirements are precise, so the excavation contractor must be able to use a level and transit to match the grade posted by the surveying crew. After the foundation contractor pours the footers and stem wall, the excavation contractor backfills around the new foundation.

Contracting

Excavation contractors are business owners and are considered subcontractors because their job is often just one part of a larger project. A homeowner can contact an excavation contractor for a personal job, such as digging for a swimming pool, but the excavation contractor won’t oversee the entire project. Excavation contractors often work under the direction of general contractors, who solicit bids, coordinate subcontractor timelines and pay the excavation contractor when he completes his part of the project.

What is Wrecking Demolition

A wrecking ball is a heavy steel ball, usually hung from a crane, that is used for demolishing large buildings. It was most commonly in use during the 1950s and 1960s. Several wrecking companies claim to have invented the wrecking ball. An early documented use was in the breaking up of the SS Great Eastern in 1888-1889, by Henry Bath and Co, at Rock Ferry on the river Mersey.

DCI DEMOLITION

In 1999, the wrecking ball was described as "one of the most common forms of large-scale coarse demolition."[1] Although the wrecking ball is still the most efficient way to raze a concrete frame structure, its use is decreasing. With the invention of hydraulic excavators and other machinery, the wrecking ball has become less common at demolition sites as its working efficiency is less than that of high reach excavators.

Construction and design
Modern wrecking balls have had a slight re-shaping, with the metal sphere changed into a pear shape with a portion of the top cut off. This shape allows the ball to be more easily pulled back through a roof or concrete slab after it has broken through.

Wrecking balls range from about 1,000 pounds (450 kg) to around 12,000 pounds (5,400 kg). The ball is made from forged steel, which means the steel is not cast into a mold in a molten state. It is formed under very high pressure while the steel is red hot (soft but not molten) to compress and to strengthen it.

WWW.DCI.BZ

Method of use
To demolish roofs and other horizontal spans, the ball is typically suspended by a length of steel chain attached to the lifting hook of a crane boom above the structure, the rope drum clutch is released and the ball is allowed to free-fall onto the structure. To demolish walls the ball is suspended at the desired height from a crane boom and a secondary steel rope pulls the ball toward the crane cab. The lateral rope drum clutch is then released and the ball swings as a pendulum to strike the structure. Another method for lateral demolition is to pivot the crane boom to accelerate the ball toward the target. This is repeated as needed until the structure is broken down into debris that can easily be loaded and hauled away. The demolition action is carried out entirely through the kinetic energy of the ball.

Modern equivalents
The advancement of technology led to the development and use of blasting charges, safer than dynamite and more efficient or practical than wrecking balls, to destroy buildings. The most common use of blasting charges is to implode a building, thus limiting collateral damage; see demolition. Wrecking balls are more likely to cause collateral damage, because it is difficult to completely control the swing of the ball.

DCI DEMOLITION

However, wrecking balls are still used when demolition may not be possible due to local environmental issues or asbestos/lead building content.

Demolition of Housing

See also: Buildings Unfit for Human Habitation, Demolition Permit

What Permits Do you Need?

You need a demolition permit to remove housing. If you plan to deconstruct housing (to reuse material) instead of demolishing it, you may be able to get a permit before your building or use permit is issued. See our residential deconstruction permit page for details.

There are rules restricting demolition of housing that do not apply to demolition of non-residential buildings. You can demolish housing only:

• In a single-family zone, if it has not been used as rental housing within the last 12 months
• If you have already been issued a permit for a new use or a new building at the site
• If the housing will be relocated
• If we issue an order declaring the property unfit to live in

You cannot demolish housing to create non-required parking. There are also limits on demolition of landmarks; consult the Department of Neighborhoods Preservation Program. You need to follow the tenant relocation rules if the building you plan to demolish has tenants.

You must meet asbestos survey requirements before you can obtain a demolition permit. Contact the Puget Sound Clean Air Agency at (206) 689-4058.

Research the Code

Read the Seattle Municipal Code (SMC) section on demolition of housing, SMC 23.40.006.

About Hauling Truck Services

Most hauling trucks have a two-axle design, but two very well known models from the 1970s, the 350T TerexTitan and 235TWabco 3200/B, had three axles. Haul truck capacities range from 40 short tons (36 t) to 400 short tons (363 t).

Large quarry-sized trucks range from 40 to 100 tons. A good example of this is the Caterpillar 775 (rated at 70 short tons (64 t)). Quarry operations are typically smaller than, say, a gold/copper mine, and require smaller trucks.

The industry uses demolition hauling service as an important step in the process.
The logistics of the number of trucks used in demolition project depends on the size of the demilicion.

A balance between quantity and capacity should be used. So saving time is guaranteed cleaning and debris removal.

It is very important to know the capacity of the trucks to use the right amount.

You must select the material that can be recycled and trucks can know where to put the waste from demolition.

Personnel operating the equipment must be highly qualified. Our truck drivers have the experience to do the job very well. Regularly receive training in waste management and implementation of new techniques.

Concrete Driveway Fundation Steps by DCI Demolition Company

To ensure your concrete driveway will look good for years to come, there are important steps that DCI Demolitions Company makes during installation. How well your driveway looks and works long term is largely due to the quality of workmanship and materials that go into it. To help ensure a trouble-free way



A properly prepared sub-base
The uniformity in both soil composition and compaction is the key to good subgrade-one that will provide adequate support, ensure uniform slab thickness and avoid liquidation of the slab and structural cracking. Soft spots should be removed and replaced with good material, such as gravel or crushed stone. Many Western states have expansive soils. Under these conditions, from 2 to 8 inches of crushed rock should be used as sub-base material, depending on the degree of expansion. If you are not sure about the characteristics of the soil in your area, consult a soil engineer.

Do not let the concrete is placed on the subgrade must be completely dry Spray the first sub-base to cushion will keep water fresh concrete is absorbed.

Plate compactors and rollers are the most common machines used for compacting the subgrade residential driveways.

Correct concrete mix
Mix design will impact the performance and longevity of a concrete driveway.

Control Joints driveway can be incorporated in a decorative pattern.

Joints positioned correctly
To help prevent random cracking, control joints should be placed at a maximum distance of 10 feet of a roadway slab 4 inches thick. While random cracks are generally not a structural problem and not reduce the life of the road, which can be an eyesore. Also avoid joint patterns that produce rectangular or triangular sections. The depth of control joints is also critical. The concrete installer must hand tool or saw cut to a depth equivalent to one quarter of the thickness of the slab (or 1 inch for a slab 4 inches).

Reinforcement
The use of steel reinforcement provide additional structural capacity to your driveway and is especially important if the slab will be exposed to heavy traffic. The reinforcement will not prevent cracks, but will help keep them together if they occur. Reinforcement may be wire mesh or ½ inch (# 4) of the steel reinforcing bars placed in a grid pattern with a spacing between bars of approximately 12 inches. In any event, the blocks must be used to maintain low reinforcement centered within the concrete.

Placing concrete in the proper thickness
The thickness is the main factor (even more than the strength of concrete) in determining the structural capacity of a driveway. Place concrete with a minimum thickness of 4 inches. Increasing the thickness of 4 inches to 5 inches will add approximately 20% of its specific cost, but also increase the capacity of almost 50% of its driveway. In DCI Demolitions Company also considers the thickening of the edges of the road for 1 or 2 inches to provide additional structural support in the most likely area that is subject to a heavy load, with the thickened section extending from the edge of the slab 4-8 inches.

Suitable finish
The largest errors occurring during the finishing of concrete walkways are overworking and performing surface finishing operations, while the bleeding water is present.

The finish is usually a three-step process. We at DCI Demolition Company relaizamos the following:

Level or strike the concrete with a ruler to achieve a uniform surface.
Float concrete with a wood or magnesium bullfloat before bleed water accumulates.
Apply a simple broom finish to enhance traction, unless the plans call for stamping the road or applying other decorative textured finish.
The final finish with a steel trowel is unnecessary and can actually do more harm than good to seal the concrete surface prematurely and preventing water evaporation bleeding.
Proper drainage
To eliminate standing water in your driveway should slope toward the street, away from existing structures (like your house and garage) a minimum of 1/8 inch per foot. If proper drainage is prevented, because the concrete slab is wedged between two structures, you may need to install a drain that collect water at a low point in the concrete and divert it away.

Curing techniques appropriate
Cure the concrete as soon as finishing is completed. Curing of concrete is the final step of the process, and one of the most important. Unfortunately, it is also one of the most overlooked. In extreme cases, failure to cure the concrete immediately after the final finish can result in strength reductions up to 50% by reducing the resistance of concrete to weather effects and increasing the possibility of defects in the surface.

Curing methods include covering the concrete with plastic sheets or blankets moist curing, continuous spraying and the application of a curing compound forming liquid membrane. For slabs that will be acid stained, wet curing is the best approach, since a curing compound should be completely removed to allow the acid stain to penetrate. To cure the most common single or integrally colored concrete forms, however, is the use of a liquid curing compound. Read more about why it is important concrete curing and how.
