Bob Ball, who runs H&R Salvage of Mitchell, is in the business of destroying blades, something he says hes already doing with success in Iowa, where the issue has become a hot topic with increasingly aging blades.

Ball is already leading the demolition and burying of turbine blades in Lake Mills, Iowa, working out agreements to cut up old General Electric turbine blades and putting them into a Waste Management landfill.

They dont let just any hillbilly get their blades and cut them up, he told the Davison County Planning Commission. Im the most successful of anyone they know for chopping them up.

On Tuesday, the Davison County Planning Commission approved H&R Salvage to expand its existing operation to dismantle wind turbine blades. Final approval will be considered by the Davison County Commissioners on Dec. 10. The county does not have to rule on the landfill decisions.

Meeting with the Davison County Commission earlier on Tuesday, Mitchell Public Works Director Kyle Croce and Street and Sanitation Superintendent Kevin Roth said theyve been approached by H&R Salvage to put up to 700 tons of old wind turbine blades from Wessington Springs into its landfill.

Those blades would be cut down to 50-foot pieces and eventually down to 3-by-7-foot sections and would be placed in a ravine at Mitchells Old Landfill, which is located at 2801 E. Havens St. (Mitchells current 160-acre landfill, located southeast of the city on 257th Street, would not be taking wind turbine pieces, the city officials said.)

Those turbine pieces are made of non-toxic fiberglass and essentially dont decay or disintegrate over time. Its that potential white elephant factor that makes them a burden when theyre no longer usable for wind turbines, drawing the concern of Davison County Commission Chairwoman Brenda Bode.

Youre burying something that will never go away, Bode said. This is taking up land, making a footprint that is never going to be used. We need to do some due diligence.

Currently, Mitchell takes commercial trash and garbage, rubble and building debris for $36 per ton. Croce and Roth said they would consider a fee of $65 per ton for commercial waste outside of the landfills general five-county service area.

NextEra Energy owns the Wessington Springs Wind Energy Center, which has 34 turbines and has been in commercial operation since 2009. Earlier this year, NextEra began work to replace the previous 77-meter blades with longer, 91-meter blades, which can capture more wind energy and convert it to electricity with more efficiency. Blades usually weigh between 14 and 19 tons.

Croce said the city has not yet made any commitments to take the blade pieces, and said they want to have the plans approved by Davison County. Roth also said the city is changing the permitting on its old landfill to allow for up to 5,000 tons of garbage in a year, starting on Jan. 1. Currently, the landfill is permitted for 500 tons.

Thats why were considering the higher fee, Croce said. We want to deter haulers from coming in and using our landfill. We want them to be using the landfills in their contracted area.

Bode said that neither the city nor the county has the money for another landfill, so the decisions on how much material Mitchell is willing to take needs to be weighed carefully.

Is it worth filling it up with wind turbines? Everyone wants someone else to take their garbage, she said.

Commissioner John Claggett alluded that wind energy companies have been shopping around to various municipalities and counties to find places to take their old blades. Sioux Falls, for example, stopped allowing turbines to be dumped at the citys landfill, but only after two Iowa wind farms dumped more than 100 turbine blades, each measuring more than 120 feet long, the Argus Leader reported.

Ball said the South Dakota Department of Environment and Natural Resources generally wont let landfills take out-of-state turbines. He said he will only take 12 blades per day at its salvage location just west of Mitchell, because thats as much as his employees can get through in a days work. In Iowa, they are buried in a large pit, Ball said, and thousands of blades have been broken down to the point past recognition.

Its a lengthy process but once its done, its done, said Ball. These blades are going to have to go somewhere for a long time.

A time capsule will be uncovered underneath the Communications Center when the UI begins demolition in 2020.

The Communication Center is seen on Thursday, Sept. 19, 2019. The Center is the former location of the UI School of Journalism and The Daily Iowan newsroom. The Board of Regents have voted to raze the building.

The Communication Center is seen on Thursday, Sept. 19, 2019. The Center is the former location of the UI School of Journalism and The Daily Iowan newsroom. The Board of Regents have voted to raze the building.

Demolition of the University of Iowa Communications Center, which is more than a half-century old, will uncover a time capsule placed beneath the buildings floorboards 33 years before the capsule was supposed to be retrieved.

Built in 1953, the Communications Center formerly housed both the journalism school and The Daily Iowan. The building is slated for demolition after graduation in spring 2020, said Wendy Moorehead, strategic communications manager of UI Facilities Management, and the crew will hand off the unopened capsule to the journalism school following its recovery.

Moorehead said that construction fencing will be implemented in January, asbestos abatement on the Communications Center will occur through March, and the actual demolition of the building will begin in May. The budget for the project is $970,000, she added.

Substantial completion will occur in early August, Moorehead said. Permanent restoration of the site into a greenspace with pedestrian plaza will occur under a separate project in 2021.

The DI reported in 1953 that the time capsule was slated to contain manuscripts, equipment items such as film and tape, and the script of a movie.

Former UI journalism professor Edward Mason was quoted in a 1950s DI article stating that the time capsule aimed to present an interesting and meaningful picture of the mass-media world of 1953 for the communications profession of 2053.

Not only will it provide record of today, but it will also mirror our hopes and aspirations for the future, Mason said at the time.

Longtime former DI Publisher Bill Casey said that it was time for the aging building to be torn down.

It was a great location, but in the summer it was too hot, and in the winter it was too cold, Casey said. It leaked when it rained, but great work was done out of there through the hard work at The Daily Iowan.

The center was poorly built and had temporary walls, Casey said, so the DI was moved to the Adler Journalism Building following the buildings construction in 2005.

I remember conversation about the time capsule that existed underneath the Communications Center and what was possibly in it, Casey said. There are surely old copies of the DI, but Im not sure about what else.

UI history Associate Professor Nick Yablon published a book about time capsules and their importance.

Yablon said the time capsule wouldnt technically be called a time capsule at all because of its location.

Instead, Yablon said, the object would be called a cornerstone, which requires the demolition of a building to be retrieved, while a time capsule does not. Nevertheless, he said the terms are typically interchangeable and witnesses can learn similar things from both.

We might learn about how students viewed their own present and life as a student in that year. It might contain predictions about the future, Yablon said. It would be interesting to see where our society lies compared to their predictions.

Yablon said that people criticized the production of time capsules in the 50s, and many wondered why sane people spent time and money on the object without understanding the importance of it.

We can use the past to legitimize parts of history and use memories to see how people viewed their own contributions to history, Yablon said.

Residents relieved as demolition starts on collapsing buildings in Tala - Cyprus Mail

Demolition expert S.B. Sarwate on Tuesday said that razing of the illegal flats at Maradu through controlled explosion would not have any significant impact on any structures in their vicinity.

Talking on controlled explosions at an event organised by the Institution of Engineers India, Kochi chapter, Mr. Sarwate, roped in by the government to help it pull down the structures that violated the CRZ rules, said that any normal structure would develop minor cracks after five years of construction. The character of soil in places like Kochi accelerates the process. He maintained that there was no need to link the cracks spotted at houses in the neighbourhood of the flats to the controlled explosion proposed for razing the towering apartment complexes to ground.

Mr. Sarwate, who holds a record in guiding over 250 demolitions through controlled explosions, said that from his experience, there was no need to harbour apprehensions about any danger from the proposed demolition at Maradu. The concerns raised by the residents in the neighbourhood had come to his notice, he said. But their fear is unfounded, he said.

The demolition, he argued, would be eco-friendly, as it would give rise to better atmosphere. It doesnt generate any chemicals. The concrete debris from the demolition can be removed and disposed of in about eight to 10 days, Mr. Sarwate said.

Demolition will not impact nearby structures: Sarwate - The Hindu

A decision on whether to demolish Napier's civic building and library has been put off after doubts were raised about whether it was severely earthquake-prone as previously thought.

Both buildings have been empty since 2017 after an assessment found them to be earthquake prone and council staff have recommended demolishing both so the site could be sold or leased to a hotel company.

The 2017 Strata assessment found the civic building only met 10 percent of legal requirements for earthquake strength under the New Building Standards, while the library only met 15 percent.

However, former top EQC structural engineer Graeme Robinson told councillors this morning that his own assessment of the building in 2010 found it fully complied with earthquake standards.

"I assessed the main office building at not less than 100 percent of the New Building Standard for current earthquake design loadings, and I found that the council chambers had some structural limitations, so I recommended that it should be strengthened or demolished within 20 years."

The Strata report recommended the building be strengthened or demolished within 7.5 years, but it did not explain the level of "earthquake horizontal force" applied in its calculations, Mr Robinson said

"That is a fundamental issue I have with that Strata report. Without identifying the level of horizontal force that a new building of the same style would now be designed to resist, it is impossible to stats what percentage of that horizontal force would cause the building to collapse."

Strata appeared to have identified two columns that were expected to fail in an earthquake, despite rigid walls absorbing the bulk of the shocks, he said.

"And it is only after they have yielded and deflected sideways by significant distances that the flexible columns will be called upon to resist horizontal forces."

"The Strata assessment appears to reverse this sequence of structural failure," he said.

The Strata report also calculated that the building would collapse at a very low-level of shaking, yet it had survived four large earthquakes since it was constructed in 1968, Mr Robinson said.

Napier City Council's director of city strategy Richard Munneke told councillors the proposal to demolish the civic building was not around seismic strengthening, but that it was no longer fit for purpose.

"The civic building was prohibitively expensive to get up to modern building standards. It was decided we could sell the site for other purposes ... the demolition is one step in that process and no hotel to date has wanted anything to do with the current building in terms of building a hotel on that site," he said.

The council was in discussions with a hotel group to sell or lease the site, it confirmed.

However, in light of Graeme Robinson's report the council voted to delay its decision until the next council meeting on December 19.

Napier demolition put on hold after doubts raised over severity of earthquake risk - RNZ

This years anniversary of the Babri Masjid demolition comes after the historic SC verdict of Nov 9 that the disputed land would be given to the Hindu parties.

The Hyderabad city police have imposed Section 144 from Thursday to Saturday across the city. The move by the police comes a day ahead of the 27th anniversary of the Babri Masjid demolition on December 6.

We have received information that certain groups are trying to create disturbances affecting public peace and order in the city, inciting communal animosity between different communities on December 6, the police said, in a statement to media.

Police have said that Section 144 will be in force from Thursday 6 pm to Friday 6 am.

The police have prohibited all kinds of processions, dharna, rally (including motorcycle rally) or public meetings during the period. Prohibition has also been placed on individuals or groups of individuals from making any speech, gesture or displaying pictures, symbols, placards, flags etc, which are likely to create religious animosity or hatred between different communities or individuals or is likely to cause disturbance to the public peace and order in the limits of the city, except those permitted by the police.

This years anniversary of the Babri Masjid demolition comes after the historic November 9 verdict by the five-judge bench of the Supreme Court (SC) that gave a unanimous judgment in the Ayodhya case. The Supreme Court held that the disputed land would be given to the Hindu parties.

The SC also ordered alternate land measuring five acres for the Sunni Muslim Waqf Board. The verdict was given by a bench headed by Chief Justice Ranjan Gogoi, and comprised Justices SA Bobde, DY Chandrachud, Ashok Bhushan and S Abdul Nazeer.

The Centre has been tasked with the creation of a Board of Trustees for the construction of the temple at the disputed site. The trust has to be set up within three months from the verdict and the trust will take over the management of construction of the temple.

The disputed 2.77 acre land, which includes the inner and outer courtyards, will be handed over by the Centre to the trustees. The rest of the land will also be handed over to the trustees.

Detroit The City Council's rejection of the Duggan administration's request to add a $250 million bond proposal to the March ballot will stand.

The City Clerk's Office on Monday confirmed that none of the panel's nine members had filed a motion to have the vote reconsidered by the 4 p.m. deadline. The council turned down the proposal by a 6-3 vote last Tuesday after weeks of contentious debate and a packed town hall meeting that drew upwards of 500 residents, activists, clergy and lawmakers.

The council's vote came soon after Detroit's auditor general released a critical report of city-administered demolition work that cited unreliable data, a lack of transparency and documentation and other failures.

Duggan has said herespected the council's decision and intended to meet with each member to discuss alternatives to the original measure that met opposition over its timing and a lack of details over how the city-funded program will operate going forward and who will oversee it, among other concerns.

Duggan and council members have not counted out the prospect of a proposal to put a bond initiative before voters in November 2020.

The mayor's effort to come up with additional funding for demolition comes as some $265 million in federal Hardest Hit dollars wind down. Duggan has touted that the30-year bond would have wiped out the city's remaining 19,000 blighted houses by 2025.

Under its debt-cutting bankruptcy plan, the city gets $50 million each year for blight, $30 million of which is earmarked for residential demolition.

Crews removing the final piece of the Alaskan Way Viaduct. (Jon Jussero, KIRO 7)

After months of work, the demolition of the Alaskan Way Viaduct has finally come to an end.

Crews finished clearing the final pieces of the viaduct late Thursday morning, for what the Washington State Department of Transportation labeled a giant recycling project.

To that end, concrete from the demolition was reused to fill the Battery Street Tunnel. In total, roughly 240 million pounds of concrete was recycled, as well as 15 million pounds of steel rebar.

Nothing about this job was easy, Secretary of Transportation Roger Millar said in a news release. The demolition project was a remarkable accomplishment as the viaduct stood perilously close to buildings and utilities and a critical rail corridor.

Crews have been working since February to dismantle the structure thats stood along Seattles waterfront since the 1950s.

If youre looking to get a piece of the action, youre in luck WSDOT is giving out concrete pieces of the viaduct free of charge.

You can get your piece of the viaduct at the Waterfront Spaceon the corner of Western Avenue and Union Street, any time between Wednesday and Sunday from 12 p.m. to 5 p.m. The space is currently a showcase for Seattles reimagined waterfront, run by Friends of the Waterfront Seattle.

In the days ahead, the waterfront along Alaskan Waywill be completely overhauledto include a 20-acre park and public space, a promenade and bike path, an overlook walk, a seawall, and more.

Construction has already begun on two-way bus lanes on Columbia Street to connect transit between 3rd Avenue and SR 99 south of downtown.
