Tideway unveils vision for new public space along the River Thames
Tideway London
September 2018


Quote:
New images that offer a vision of how the River Thames will look in the future have been released by Tideway, the company building the Thames Tideway Tunnel.

The images depict seven new public spaces that are to be built as part of works to build the tunnel, more commonly referred to as London’s ‘super sewer’.

The 25km super sewer is a vital infrastructure project that will modernise London’s ageing sewage system and dramatically improve the environment by preventing millions of tonnes of sewage overflowing into the river each year. But for Tideway, it’s more than just cleaning up the river.

Sir Joseph Bazalgette, who designed London’s original sewer system over 150 years ago, built out onto the river creating the Victoria, Albert and Chelsea Embankments. Tideway will be honouring that legacy by also building out onto the river, creating seven new landscaped areas which will include sites at Chelsea, Albert, Victoria and Putney Embankments, as well as at Blackfriars Bridge, King Edward Memorial Park and Heathwall Pumping Station.

Parts of the new spaces at Victoria and Chelsea Embankments and at King Edward Memorial Park will be ‘floodable’ at high tides, giving Londoners the first opportunity of its kind to dip their toe in what will be a cleaner River Thames.

Roger Bailey, Tideway’s Chief Technical Officer, said: “When Sir Joseph Bazalgette unveiled his vision for London’s sewer system more than 150 years ago, he changed the look and character of the city with the creation of the Chelsea, Victoria and Albert Embankments. Similarly, the construction of London’s new super sewer will create three acres of new public space designed to reconnect the capital’s residents and visitors with the River Thames. In keeping with Bazalgette’s legacy, the new public spaces will be designed to enhance the environment and provide a lasting legacy. Our ambition is to celebrate the River Thames as the heart of London.”

Tideway’s designers have worked closely with artists at each location to develop a trail of contemporary artwork that explore themes from the River’s history and its significant role in the city’s development.

The new public spaces will follow the example set by Bazalgette, as demonstrated on the embankment river walls which includes the now iconic sturgeon lamp posts.

Tim Heading, Architecture and Landscape Lead, Arup Atkins Joint Venture, said: “A healthy River Thames plays an essential role in the wellbeing and prosperity of London and its people. The Thames Tideway Tunnel will help transform the river and we are very pleased that the valuable experience, expertise and approach of the combined Arup and Atkins teams is being utilised to promote a positive change in the relationship that Londoners and visitors have with the Thames.”

Harbinder Birdi, Hawkins/Brown Architects, said: “We are delighted to be part of this once-in-a-lifetime opportunity to work alongside engineers and artists in re-imagining London’s relationship with the River Thames. In developing the designs for these ambitious new public spaces as architect for the central section, we have responded to the unique characteristics of each site; from the natural, contemplative context of Chelsea Embankment to the prominent position of Blackfriars Bridge, where the landscape tells the story of the lost river Fleet while opening up new views of St Paul’s. The sites are connected by a common aim: to bring people closer to the river.”

Steve Bell, Weston Williamson and Partners, said: “It is a tremendous privilege to be part of a project that is key to the rehabilitation of the River Thames, and to create new public spaces at the river’s edge. The team, comprising Architects, Contractors, Engineers and Artists, are working closely together to sensitively manage the impacts of the massive below-ground engineering on existing communities and physical context and deliver memorable new public realm.”

Planning policy prevents other developers from reclaiming land from the river in this way, so Tideway have a near unique opportunity to enhance people’s experience of what is London’s largest open space – the iconic River Thames.

Work on London’s super sewer is gearing up with tunnelling set to start later this year.

The plans for these new embankment extensions doesn't seem to be a well executed as the vision suggested. Possibly on the Tideway documentary, I'd heard the vision was about opening the embankment up to the river and stepping down to the water. I don't really see this being the case?

Unfortunately it looks more like dressing up an engineering solution as apposed to something more integral and less obvious.

Well, maybe it looks that way because it is "dressing up an engineering solution".

Thay are building massive sewer, not a museum or an art instalation. It is nice they try to do something positive but you can't expect they will go over the top. The whole thing is already quite expensive...

I disagree. This is often the attitude with big infrastructure projects and whilst understandable, it’s a real shame. The cost differential between doing these bits well or badly is likely less than .5% of the total budget but the difference it might make to the urban environment likely worth it.

What might London had lost if Bazalgette had had this attitude on the Embankment for example.

Bazalgette was working for a government body, in an era where government bodies were allowed or even encouraged to do things in a way that maximised holistic benefits for the population they supposedly serve, even if that couldn't be reconciled with positive numbers on the balance sheet. Of course these days we know better and the political/economic "consensus" (HAHAHAHAHAHA) is that any govt body having the temerity to operate in the black is stealing profit from the mouths of honest private sector entrepreneurs, and must be privatised immediately, whereas any govt body running in the red is proof that govt bodies are innefficient and reckless wasters of public cash and must, therefore, be privatised immediately.

Once safely privatised, holistic social benefits that will make no difference to Thames Water's bottom line can be safely ignored - hell, not just can, must be ignored, it would be immoral dereliction of duty of shareholders to do otherwise. And the dreadful inefficient wasted cost of doing things to Bazalgette standards can be redirected back to where the money rightfully belongs in an economy: bigger salaries for C-grades and bigger dividends for shareholders. Some of which can of course be shuffled off towards their dinner party media-owner mates to keep pumping out the "govt = bad, 'red tape' = bad, 'free market' = saviour" propaganda to keep this utterly crooked and dishonest intellectual "consensus" in place, and their dinner party politician mates to keep the privatisations and tax-breaks coming.

Given the way austerity has become permanent normality and the gini coefficient is staying nice and high, the system is working perfectly as intended as far as I can see.

All that said I don't really have a problem with these works, they look ok to me!

These look great, and not a 'branded experience' pavilion or privatised security guard in sight. Good stuff.

But they're not done badly? For what they are I think they're done quite well but I think it's the nature of what they are which you are unsatisfied with.

Unfortunately the engineering solution here didn't necessitate anything anywhere near as dramatic as Embankment. The extent of that reclamation was necessitated by the need for a sewer, road, and underground line.

Why is anything more than what is proposed needed? Just take this as some nice bits of public realm that we would otherwise not have but for Tideway.

Have some reservations about municipal water features because councils often neglect these leaving them as incongruous, dry eyesores. Hopefully WCC and CoL are good for keeping them functioning.

But otherwise are of the same quality as the Victorian embankment they extent which is great. Love the little wetlands elements - more of that in other places on the Thames please.

To be clear, I wasn’t necessarily criticising what’s being proposed, more the comment that money shouldn’t be spent ‘dressing up an engineering project’. I think there’s often plenty of value in doing just that and it rarely makes a substantial difference to cost.

A catalogue of engineering challenges during cofferdam and shaft construction has left the project team looking for major cost-savings.
The project’s holding company, Bazalgette Holdings Group, confirmed the total project spend so far has reached £1.48bn amid unforeseen cost pressures early on in the project.
Now contractors are being pressed to find savings and raise productivity as a value engineering exercise is undertaken and overheads are cut.
The 25km tunnel is due to be completed by 2023 at a cost £4.2bn and Tideway said it was confident the project would be completed on time and to budget.
Cost pressures were revealed as former Crossrail finance boss Mathew Duncan joined the project last week as new finance director replacing Mark Corben, whose intention to stand down was announced last year.
Key sites facing engineering challenges are at Blackfriars, where two large Victorian gas mains have caused problems, cofferdam construction at King Edward Memorial Park and Albert Embankment and shafts at east area sites.
In a statement just after the first tunnelling started last week, the firm said: “Following significant progress on the project and now having mobilised on 20 of our 21 sites, Tideway has identified several cost pressures in the programme.
“Taken together with general cost pressure across the programme this has substantially eroded available contingency.
“To mitigate the cost pressures Tideway has begun to implement cost-saving measures in partnership with our contractors and remains focussed on achieving the baseline target.
“These cost-saving measures include working with our contractors to eliminate overlap, taking measures to increase productivity, undertaking value engineering and delivering overhead savings.
“It is too early to conclude the extent to which these measures will mitigate the cost pressures, and an update will be provided on these and the cost savings programme in Tideway’s annual report and accounts next March.”
A spokeswoman for Tideway added: “There have been a number of complex engineering challenges and risks to overcome in the early stages of the project.
“With these behind us and having put in place several measures to reduce cost, our budget is intact. Tunnelling for the project started last week from our site in Battersea and we are set to complete the project on schedule and to budget.”
The interaction issues with other utilities were always bound to be problematic especially those installed over one hundred years ago. Does anybody more detail about the Victorian Gas Mains - Such as how big ?, What is the nature and condition of the existing gas pipe structure?, Is the area serviced by these mains capable of by supplied by other parts of the network?
