Bilsdale mast ‘on track to be completed this year’

A new 314-metre mast at Bilsdale remains on track to be completed by the end of the year, the company behind the plan has said.

Arqiva chief executive Paul Donovan said the firm was striving to halve the time normally taken to replace such a towering structure on one of the country’s most environmentally sensitive sites at Bilsdale on the North York Moors.

The mast provides television and radio coverage to areas in the Harrogate district, such as Ripon.

Mr Donovan was speaking at North Yorkshire-based firm Severfield’s expansive plant at Dalton Airfield Industrial Estate, near Thirsk, as it was announced the steel firm had won the contract, thought to be worth tens of millions of pounds, to fabricate the 200-tonne structure.

Arqiva is expecting the final of five investigations, from the firm’s insurance company, into the cause of the fire which destroyed the previous mast in August last year to be completed in the next two weeks.

Mr Donovan said: 

“That I’m sure will be of great interest to everybody. It’s been a source of frustration for us that it has taken so long, but we had to have due process around something as significant as this.”

Severfield, which has previously worked on large-scale projects such as the London Olympic Stadium and the London Shard, said it had been handed “tight timescales” to produce the structure in order that viewers across Yorkshire and the North-East get a full restoration of signals as soon as possible.

The coming months will see the steel fabricated by Severfield, before going away to galvanised and being turned into flat pack-style units and taken to Bilsdale for it to be reassembled in a modular way.

Mr Donovan said: 

“I’m very satisfied with the progress we are making on what will ultimately be one of Britain’s top 10 tallest structures at 314m-high, weighing 200 tonnes with lots of very complex electronics and other equipment which needs to be installed upon it.

“At the moment it is on track, but as with all things it is weather dependent, as you can only work at height when the wind is below a certain velocity, so we’re hoping for a good summer.

“Everybody has really pulled the stops out to ensure their normal delivery timeframes get shrunk without any compromise to quality. We all realise the importance to people of getting this project finished so we can have service fully restored to what it was before.”

Different design

When asked if the new structure had been designed to avert a repeat of the catastrophic incident which irreversibly damaged the previous mast, Mr Donovan replied: 

“It’s too early to be definitive about that, but if you look at this structure it’s a fundamentally different design.

“The previous mast was a cylindrical structure, but the new mast will be a lattice-based structure which actually has some benefits in its ability to tolerate wind, but also if there were any fire on a lattice-based structure it is potentially less vulnerable to the kind of catastrophic outcomes we saw before.

“The previous tower was 50 years old and technology, construction and aerodynamics have all moved forward tremendously during that time.”

Over the coming months the firm will have to report to both Ofcom and the Department for Culture, Media and Sport about its overall response.

Mr Donovan said: 

“We have responded many ways in an exemplary way, going way beyond the contractual requirements we have with our customers. 

“In terms of processes there are things which we now know we would do better, but there isn’t anything I have seen so far that would have prevented what happened.”

Improvement expected for Ripon TV viewers after transmitter fire

The operator of Bilsdale transmitter has said it anticipates “significant improvement” to television coverage in Masham and Ripon.

Fire crews were called to the mast last week after reports of smoke was reported coming from the area.

The loss of the transmitter is affecting parts of Harrogate, Boroughbridge, Kirkby Malzeard, Knaresborough, Masham, Pateley Bridge, Ripon and other locations that rely on a signal that serves the Tyne Tees region.

An update issued by the mast operator, Arqiva, last night said that it now expected to be able to give better television coverage to Masham and Ripon.

It said a 15m mast was planned for Arncliffe Wood as part of the response to the fire. However, wider coverage is not expected to return until August 28.

A statement from Arqiva said:

“As per our previous update, we now expect to have completed the improvement of TV coverage from Eston Nab, and also the installation of a further 15m mast at a site in Arncliffe Wood by the weekend.

“These two developments should deliver a significant improvement in TV coverage for viewers in the areas including Darlington, Stockton, Catterick, Leyburn, Masham and Ripon. We will update viewers on any action they need to take with further updates later this week.

“Work on phase 2 of the recovery plan continues. We still anticipate the temporary mast to be effective by 28 August.”

Meanwhile, Freeview has issued advice to TV viewers who continue to have problems with their coverage.

It includes using online streaming, such as BBC iPlayer and ITV Hub, and on-demand services.

Freeview said repositioning aerials to pick up service from another transmitter was an option. But the company added that an accredited installer should be employed to carry out the work.

It said:

“Repositioning your aerial so that it takes a signal from a different transmitter may be an option for some viewers who wish to attempt to get some signal back in the short term.

“However, there’s no guarantee that another transmitter is available (reception is highly dependent on several factors such as local geography between you and the transmitter), and the signal quality might be variable.

“If you choose to have your aerial repositioned and pay for an installer to do this, you may wish to then have it repositioned again when service from Bilsdale is restored.

“If you wish to have your aerial repositioned, please do not attempt this yourself.”
