Consultancy takes leads role in pair of dismantling contracts.

INEOS ChlorVinyls – Europe’s largest polyvinyl chloride (PVC) manufacturer – engaged sector-specific CDM coordinators and project managers RVA Group, to oversee the safe execution of these two major projects and ensure the maximisation of income from the resale of redundant plant and metallic arisings including high-value exotic alloys.

RVA commenced its role at INEOS ChlorVinyls’ Barry site after manufacturing ceased in March 2010 as part of a consolidation of activities. Having planned to decommission and clean the site before handing it back to the landlord with the plant intact, INEOS sought RVA’s isolation and decommissioning guidance. However acknowledging the financial implications of INEOS’ proposed site exit strategy, RVA conducted a series of in-depth feasibility and option studies to investigate more commercially attractive routes for the client.

Utilising its vast knowledge and experience of asset recovery, RVA recommended that INEOS hand the site back as flat slab, as plant demolition and dismantling could generate an income from the sale of the process equipment – some had potential for reuse whereas other items (as a result of their high-value metallurgy) would create a positive income stream.

To demonstrate their confidence in the proposed alternative site exit strategy, RVA agreed to work for six weeks – at risk – to test the feasibility of their solution. If the project plan had proven unachievable, RVA would have waived all costs for work undertaken during this investigatory period.

However, as RVA had anticipated, the team was able to demonstrate that the project could be delivered with significant cost savings thus reducing the financial burden for INEOS.

Now RVA is project managing the dismantling and demolition of INEOS ChlorVinyls’ production facilities including process vessels, aluminium and concrete storage silos, a boilerhouse and three steel 1,500 cubic metre storage spheres. With a 27-man team on site, and kit ranging from excavators with shears and grab buckets to an ultra long reach machine safety remains the number one priority.

Colin Hopwood, INEOS ChlorVinyls’ site services manager for Runcorn explains the reason for RVA’s extensive involvement in the Barry site project: “RVA’s role with INEOS in fact commenced with the team’s development of a detailed redundant asset management review for our Runcorn site.

“The Company drew upon its technical engineering experience to assess a number of plants, projected costs of removal, optimised sequencing and a potential rolling decommissioning programme for several areas of the 125-hectare top-tier COMAH site. The quality and integrity of this guidance not only led to us proceeding with the Runcorn works, but I also then recommended their services to a colleague heading up the Barry project.”

Since the sequential decommissioning and demolition of five redundant chemical processing plants began on the high-hazard Runcorn site in August 2010, the site has remained operational elsewhere. Meticulous planning and project coordination has therefore been essential to ensure minimal disruption and utmost safety for all parties.

Priority was given to the complex dismantling of INEOS’ four distillation columns, ranging from 40 to 60 metres in height, which had to be dismantled to a low height before the arrival of the year’s high winds. However due to their proximity to high-hazard pipelines, and given the inherently dangerous nature of hot-cutting techniques, an alternative dismantling process had to be devised. Instead RVA oversaw the more time-intensive, but far safer alternative, of using high pressure abrasive water jets that ran around the circumference of the columns’ cut lines to eliminate the flammable risks, before the top sections could be removed with a lifting nail attached to a 500t crane.

With six months of the programme still to complete, RVA is currently planning for the dismantling of INEOS’ anhydrous caustic soda plant – a procedure that will take place in May 2011. Although the asset is no longer needed by INEOS, the plant is in good condition and is being carefully dismantled for re-erection elsewhere.

Vertical drop ball preferable to “Aussies or Yanks” says New Zealand demolition man.

A demolition expert believes Christchurch’s tallest hotel, the Grand Chancellor, will probably have to be knocked down by dropping a wrecking ball through the roof above its 26 accommodation floors.

“It will have to be done straight away – it’s not the sort where you can actually deconstruct it, because it is leaning,” said Demolition and Asbestos Association president Diana Stil.

Stil is in Christchurch to join other industry experts in advising civil defence authorities on how to clear central Christchurch of earthquake debris.

“When I saw it last night it was very unstable. You can’t load it – it’s already leaning, collapsing on one side – so the scenario of a ball and crane is probably the safest as that means there is no human exposure. We believe it can’t be saved, but that’s up to construction engineers.”

Alec Burrell, of Auckland’s Burrell Demolition, said it was unlikely that controlled explosives could be used to bring down the building because that would involve long preparations requiring people to enter the building to lay them.

“But at this stage no decision can be made until things have stopped moving,” he said. “Maybe it will be possible to take off the damaged side floor-by-floor and then rebuild it on new piles. I have no idea, but it would be a lot cheaper than mowing the whole thing down and starting again. Until the engineers are allowed a proper look at it nothing can be done – it might look 10 times worse than it is.”

Mr Burrell said local contractors and structural engineers would be well up to the challenge of dealing with the building – a task which would be far more straightforward than the Newmarket motorway viaduct project.

“What concerns us is the Aussies or Yanks may say nobody around here can do it and they’ll bring in a bunch of people and God help us.”

Fire tears through Tyne Bridge Tower, Gateshead

Firefighters battled a blaze at a derelict landmark building on the banks of the Tyne yesterday.

Rush-hour commuters watched as smoke billowed from Tyne Bridge Tower, a 13-storey block on the Gateshead side of the river, currently undergoing demolition. DemolitionNews understands that the contractor on the site is MGL Demolition, but this has yet to be confirmed.

The blaze was reported to fire crews shortly before 8.40am and eight fire engines were sent to the scene on Cannon Street.

When fire crews arrived at the scene, demolition workers who had been working to bring the building down were attempting to put out the flames using fire extinguishers.

But it eventually took 22 firefighters to quell the blaze. It is believed the fire started in the lift shaft between the sixth and seventh floors.

Lightning strikes twice as second power plant falls.

The structures around the 284 East Power House in central Hanford came crashing down Friday.

It was a repeat of the explosive demolition of the power house’s near twin, the 284 West Power House, two weeks ago – except Friday’s was larger. The east power house had an additional filtration structure and a coal silo.

Crews at the 284 East Power House Friday demolished two 76 metre (250-foot) fall exhaust chimneys, three 27 metre (90-foot) tall air filter structures and a coal silo.

In addition, they brought down a nearby water tower, one of two towers familiar to Hanford workers for their “Work Safely” signs.

Worker on post=quake New Zealand clean-up punches friend.

An overstressed demolition worker who assaulted a friend on Friday night has been sentenced to do community work.

Duty solicitor Shannon-Leigh Litt said Shane David Sampson-Arps had been working on demolitions in the centre of Christchurch the February 22 earthquake.

“He had requested counselling for what he had been seeing,” she told Christchurch District Court Judge Michael Crosbie today. “He had found it very distressing, though he knows he acted out of turn by assaulting his friend.”

Sampson-Arps, a 19-year-old labourer, pleaded guilty to the assault charge at a sitting of the court at Rangiora Court House today.

Police prosecutor Sergeant Jeff Kay said the incident happened at 8pm when Sampson-Arps and his friend were in a car outside a house in Aranui.

While they waited for a friend to come out of the house, Sampson-Arps repeatedly leaned across and sounded the horn. They exchanged words about that and when they got out of the car Sampson-Arps punched his friend twice in the chest and once in the face. The victim’s shirt was torn and he had a sore cheek.

Demolition work underway on San Jose soccer stadium.

For the San Jose Earthquakes, last Thursday was Demolition Day, as the Northern California club began what could be a long process toward the completion of a new stadium.

The Quakes’ new stadium, which is expected to hold 15,000 fans, expandable to 18,000, could cost between $40 million and $60 million in an area called Airport West. Though demolition at the site has begun, the club acknowledged that it has no completion date as it waits for a signature sponsor to help finance the project.

The stadium is the latest project in Major League Soccer, which over the past few years has made the construction of soccer stadiums a priority.

Lock away your tofu; DemolitionNews is coming to the US or A.

It’s the worst kept secret this side of Charlie Sheen’s attraction toward the opposite sex; DemolitionNews is coming to America (or going to America, depending where you’re reading this).

That’s right. From 21 through 24 March, DemolitionNews will be opening a temporary editorial office at the Las Vegas Convention Center and/or The Luxor Hotel. That’s just three weeks from now so any of my American friends that have taken offence at any previous comments have plenty of time to order up the horse head accessory for my bed before I arrive in town.

Of course, the primary reason for being in Vegas is to check out all the new demolition kit on show at the ConExpo-Con/Agg exhibition. But we’re really hoping to catch up with some of our readers and demolition professionals during our flying visit.

So, if you’re going to be in town, if I haven’t offended you recently, or even if you merely have a recommendation of places to eat, things to see, or maybe even places to avoid (and please don’t say The Luxor – It could be worse, I could be staying here), please drop us a line.

And we hope to see as many of you as possible while we’re there.

Workers to help scour beaches for waste from demolished hotel.

Demolition crews will help check Galveston beaches over complaints that debris from a hotel being torn down is falling into the water.

City spokeswoman Alicia Cahill says the contractor will canvass the beach daily during low tide to remove any possible debris from the former Flagship Hotel, which was built on pilings. Cahill said Wednesday that more containment netting will be used.

Beach patrols will watch for potential glass and concrete pieces. The Texas General Land Office is also involved.

Reports confirm that two men may have died in bridge demolition accident.

Reports have confirmed that, contrary to our earlier news, TWO men may have died in the incident earlier this week on the old Mississippi River bridge near Greenville.

According to the Washington County Sheriff’s Department and Washington County Coroner Methel Johnson, the accident occurred about 2:30 p.m.

Washington County Coroner Methel Johnson tells the Delta Democrat Times that a 46-year-old worker died at the scene Wednesday and a 21-year-old employee died later at a Jackson hospital.

Johnson says the names have not been released until authorities contact relatives. The men worked for Granite Construction, a subcontractor on the dismantling project.

Unopened Vegas hotel has become the “poster child for non-confirming work”.

MGM Resorts officials, very quietly and with no public fanfare, want to demolish the unopened 27-storey Harmon Hotel, one of the components of its $8.5 billion CityCenter development.

But litigation and pinpointing blame for the troubled building will prevent anything from happening to the unfinished tower until late 2012.

In its recent third-quarter earnings statement, MGM Resorts said it took a $279 million noncash impairment charge for the Harmon and concluded “it is unlikely the Harmon will be completed using the building as it now stands.”

In an interview this week, CityCenter Chief Executive Officer Bobby Baldwin said the company has hired two sets of structural engineers to determine the building’s condition and what steps might be taken. MGM Resorts will bring in a third group of experts to analyze the building.

A report on the findings will be filed with the Clark County District Court, as part of CityCenter’s lawsuit against Perini Building Co., the project’s general contractor.

Clark County Building Department officials will not allow any construction to be done to the Harmon, which was originally designed as a 47-story hotel and condominium tower. In 2008, inspectors found structural work on the Harmon did not match building plans submitted to the county. The construction issues involved improperly placed steel reinforcing bar. In January 2009, MGM Resorts scrapped the planned 200 condominium units for the upper floors and stopped the tower at 27 stories.
