In the realm of construction, ensuring the stability and durability of a building’s foundation is paramount. At CSMANLTD, we specialise in providing comprehensive underpinning services in London, designed to reinforce and stabilise foundations for both residential and commercial properties. Our expertise in construction underpinning, box underpinning, and mini pile underpinning ensures that your structure remains safe, secure, and long-lasting.

Understanding Underpinning

  1. What is Underpinning? Underpinning is a construction technique used to strengthen and stabilize the foundation of an existing building. This process becomes necessary when the original foundation is no longer capable of supporting the structure, often due to soil subsidence, changes in soil conditions, or additional loads from building modifications.
  2. Types of Underpinning: At CSMANLTD, we offer three primary types of underpinning services:
  • Construction Underpinning: This traditional method involves excavating sections below the existing foundation and pouring concrete to extend the foundation depth and width. It’s ideal for enhancing the load-bearing capacity of the structure.
  • Box Underpinning: This technique involves creating a reinforced concrete box around the existing foundation. It provides additional support and is often used in situations where the foundation needs extensive reinforcement.

Basement Construction London – What You Need to Know 

Basement Construction London: Adding extra living space to your home can be a great way to increase its value and make it more appealing to potential buyers. But, with space at a premium in London, it’s important to consider all of your options before you start construction. 

Many people in London choose to build basements in their homes, which are useful for a wide range of purposes. 

Underpinning basement construction 

Underpinning basement construction: In many homes today it is common to find a basement that has been designed, either during construction or at a later point by the owners, to function as a fully functional addition to the home. In some cases, the basement is used as a recreation room, while in others it may contain a bedroom or two (especially for teenagers), a bathroom, a kitchenette and one or more closets. 

The most important factor in determining whether your basement requires underpinning is a structural inspection. If you notice cracks in the foundation walls that are wider than a quarter inch, diagonal cracks, or movement of the building from its original position, then it is time to call in an expert. In most cases, underpinning will be necessary to correct faulty or unstable foundations. 

This process involves digging out sections of the existing foundations and filling them with concrete, or using piles driven into the ground to transfer load to deeper supporting soil. It is a highly specialist operation and should only be undertaken by an experienced contractor. 

Another benefit of underpinning is that it creates more headroom, making it possible to install better lighting fixtures. This in turn allows more natural light into the basement. In addition, homeowners are able to access the mechanics of their basement such as plumbing and insulation works, giving them the opportunity to repair any problems. 

Garden Basement Construction 

Creating extra space in your home can be a challenging task. But with the right basement construction contractor, your project can become a reality. Look for contractors that are reputable and have experience in the industry. You should also choose a company that offers competitive pricing. They should provide clear, detailed estimates and timelines to complete your project. Additionally, they should be willing to answer any questions you may have. 

The cost of Garden Basement Construction depends on the size and depth of the basement. To minimize costs, opt for a simple design and avoid constructing basements that will require extensive excavation work. It is also important to select the correct materials for your project. For example, choosing vinyl or laminate flooring will help you save money compared to more expensive options. 

Before beginning the construction of your basement, consult with your local council about their policies on basement extensions. The stance of each council will vary, but some will allow you to build a basement without planning permission, while others may require that you submit a full application. 

If you need to submit a full application, make sure that you follow all of the guidelines carefully. Additionally, it is essential to service a Party Wall Notice before starting construction work to ensure that your neighbours are aware of the work being carried out. 

Basement Construction London 

When it comes to basement construction in London, there are a number of things that need to be considered. For instance, you’ll want to make sure that you hire a contractor with the right experience and expertise. You’ll also want to choose a contractor that has good references and a proven track record. Finally, you’ll want to make sure that the contractor is licensed and insured. 

One of the best ways to get a quote for your basement is to contact a specialist construction company. These companies have the knowledge and expertise to create a basement that is both functional and aesthetically pleasing. They can also help you make sure that your basement is in compliance with local codes and regulations. 

Another important step is to consult with a structural engineer. This expert will design the basement shell and core. They will take into account all the survey information available and your project requirements. They will also create a detailed schedule and plan for the construction process. This will ensure that your basement is built to the highest standards. 

Finally, it’s a good idea to consult with your neighbours before starting any basement excavations. This will prevent them from being surprised by diggers and jackhammers on their doorstep. It’s also a good idea to warn them that the work may cause some noise and disruption, and to explain how they can mitigate this. 

Until recently, London’s boroughs had little in the way of regulatory guidance to shape and control residential basement construction. Some had a specific policy in place, but most did not. The result was a wave of excavations. 

It was a trend that made headlines with stories of noise complaints, vibration, and even subsidence caused by retaining wall piling operations and basement excavation. But even as the stories rolled in, the excavations continued. 

There were even reports of entombed JCBs left underneath oligarch’s homes because it was too risky and expensive to lift them out (although we think there might be a metaphor in there somewhere). The media seemed to get in on the action, publishing articles like How to pull off a stunning three-storey basement extension or drooling over Gordon Ramsay’s PS7m renovation. 

But there were also plenty of people who were irked by the disruption and expense. Some complained about their ‘selfish’ neighbours who were digging down below their properties while they worked, causing them to be constantly disturbed by noise and dust. Others blamed the basement works for their own structural problems, such as a subsidence claim by one celebrity. 

But the fact is, there are ways to minimise the impact on your neighbours and still get those amazing extra rooms you want. The key is to do your homework and talk to your neighbours before you start work, as well as to understand how much the addition will add to your property in terms of additional square metres.

Marathon’ bridge build completed on HS2

Contractors on HS2 have completed a ‘marathon’ bridge build at Streethay near Lichfield involving 18 specialist construction companies.

 

 

Work involved excavating 14,000 tonnes of earth, building a 140 metre retaining wall and moving a 2,600 tonne bridge deck 130 metres into place under the South Staffordshire freight railway.

The work was carried out during a 10 week blockade. It was completed by HS2’s civils contractor in the West Midlands, Balfour Beatty VINCI, and designers Mott MacDonald as part of a Design Joint Venture with SYSTRA (MMSDJV), together with teams from 18 specialist supply chain companies.

At the end of July, the 2,600 tonne bridge deck, which had been cast on land adjacent to the railway was moved 130 metres into position using self-propelled modular transporters.

Since then, each side of the bridge was backfilled, the rail tracks were reinstated, with the railway line was successfully handed back to Network Rail last week and now reopened.

The 25 metres long and 18 metres wide Streethay overbridge sits within HS2’s Streethay cutting and will enable HS2 trains to travel under the existing railway between Birmingham and Crewe.

Through design development, Mott MacDonald engineers were able to reduce the total length of wall structures for the railway at Streethay from 1.6 kilometres to 420 metres, meaning 80% less concrete is needed – saving around 420,000 tonnes of carbon, supporting HS2’s ambition to cut carbon on the project.

The Streethay bridge sits on top of the larger 420 metre long retaining wall structure which will have two additional bridges crossing it – the south bound A38 slip road bridge, and the Rykneld Bridge which carries the A38 north bound slip road and the A38 north and south bound carriageway.

At its peak, over 150 people worked on the complex construction operation, with teams from 18 specialist companies, delivering design, surveys, piling works, bridge build, concrete pouring, crane operations, reinforcements, modular transportation, track and systems removal and reinstatement.

The work was delivered in parallel to the construction of the nearby Fulfen Wood bridge, which involved moving a giant 6,200 tonne single span structure under the West Coast Main Line – the UK’s heaviest drive to install an intersection bridge.

David Millar, Rail Interface Manager at Balfour Beatty VINCI said: “The successful delivery of this complex and challenging piece of engineering near Lichfield is another proud moment for Balfour Beatty VINCI on the HS2 project.

“It’s only been possible thanks to the skill, dedication and support shown by the project team over the past few years, including our supply chain. Together, we’ve had to work around existing transport infrastructure, including the South Staffordshire freight railway and the A38, making this achievement even more rewarding.”

Prior to the railway blockade, retaining walls were installed on either side of the railway, enabling the areas to be excavated. The bridge deck was constructed on land adjacent to the existing railway, 130 metres from its final position.

Once the railway was closed to freight trains, the track and embankment were removed. Bachy Soletanche Balfour Beatty Ground Engineering joint venture then installed an additional 76 secant piles measuring 1.3 metres diameter and 30 metres deep, linking to the piles they installed prior to the blockade, to create two retaining walls which act as the walls for the bridge.

A concrete capping beam was installed over the retaining walls, then the bridge was moved into place using self-propelled modular transporters with 344 wheels. Concrete was poured to attach the deck to the capping beam, the embankment was back filled using 2,500 tonnes of structural backfill, on either side of the bridge, before the railway line was reinstated.

The 18 companies which delivered the project were:

J. Murphy & Sons constructed the bridge deck and the concrete elements during the blockade
Bachy Soletanche Balfour Beatty Ground Engineering JV (SB3) undertook all piling works, both before and during the blockade
The bridge parapets were made by Explore precast
Podtrak and RSS Infrastructure delivered rail systems work
Balfour Beatty VINCI delivered earthworks
Pile break-down was by Pile Breaking Systems UK Ltd
Trackway supplied by TPA
Jacking the structure and modular transportation by Mammoet UK
Survey works track monitoring by Aecom
Crane supply by King Lifting supported by BBV lifting teams
Concrete provided by CEMEX
Reinforcement by ROM – specialist reinforcement manufacturers
Temporary works by RMD
Permanent works design by Design JV (Mott Macdonald and Systra)
Temporary works design by Taylor Woodrow

Innovation Showcase | Track-free travelling formwork drives pace of HS2 green tunnel work

Innovative moving formwork is helping to speed construction of High Speed 2’s Copthall Tunnel in north west London.

Copthall Tunnel is one of five green tunnels being built along Phase 1 of High Speed 2 (HS2) between London and Birmingham.

Situated between HS2’s Northolt Tunnel and the Colne Valley Viaduct, the 880m long reinforced concrete Copthall Tunnel will blend into
its natural surroundings, covered with trees and plants once construction is complete.

The project is being delivered by Skanska Costain Strabag Joint Venture, with Kilnbridge appointed to complete the reinforced concrete works. Making the tunnel a concrete reality has been possible with custom formwork travellers engineered by Peri’s specialist infrastructure team.

As the travellers were expected to be in use over an 18 month period, the main drivers influencing their design were durability, productivity and sustainability.

To support the specified construction sequence, Peri’s engineers designed two carriages which enabled the site team to cast the walls and roof slab simultaneously, ultimately accelerating the programme. These carriages comprised four units in total, two for the wall and two for the roof.

The carriages are designed to reduce material, manual labour and craneage as the main operations such as striking, positioning and travelling are completed hydraulically.

The wall forms are built from special modular steel panels. Each set is designed to build 20m long and 7.5m high walls.

The panels are suspended from a carriage which is designed using off-the-shelf components from Peri’s Variokit range, with some specially fabricated connection parts. Variokit rails provided additional support for the formwork, reducing through ties to less than half the quantity required in a traditional panel system.

“We’ve been able to save around five days per wall in comparison to traditional formwork systems, as we can complete installation and prepare the system for concreting in one day,” says Kilnbridge project manager Teresa Martin.

The internal and external formwork on the wall carriages raise, lower and retract hydraulically, eliminating crane use and reducing labour requirements and cycle time by over 80%.

The roof carriage is built from a mix of special and standard components. In addition to fully supporting the rebar and concrete load, it features hydraulic cylinders which enable the traveller to be lowered, collapsed, pushed under the carriage in front and repositioned to allow rebar fixing and pouring operations to be concurrent. 

Peri senior sales engineer Dan Biggs says: “Special steel formwork was ideal for this project as the forms can be reused up to 30 times, so there is an obvious material saving advantage in addition to time savings, as panels do not need refacing, unlike a
plywood faced system.”

Following on from the installation of the roof traveller, the next steps will be progressing the tunnel so all three elements – base slab, tunnel walls and roof slab progress concurrently without conflicting. Tunnel construction is expected to be completed by February 2025.

Meet the company using discarded oyster shells to cut energy costs and keep France’s buildings cool

Cool Roof France has found an innovative way to use the 130,000 tonnes of waste oysters produced every year in France.

As heat waves continue to scorch Europe, many of us are looking for cheap and innovative ways to keep our homes or workplaces cool.

While air conditioning often proves effective, its environmental cost contributes further to the climate crisis.

So what if we look into the past and to other parts of the world for inspiration and startpainting our roofs white?

“This technology is just pretty old actually, but this is quite innovative to make it so technical,” says Julien Martin Cocher, deputy CEO of Cool Roof France.
But does having a white roof really make a building cooler?

What is oyster shell roof paint?

Cool Roof France (CRF) is on a mission toreduce the ambient temperature inside buildingsin a sustainable and cost effective way.

Traditional paint is made up of calcium, solvent and water.

“The oyster was at the beginning just to use a waste that we are finding quite easily in the west part of France and to replace this calcium that we are usually finding [in paint],” Julien explains.

Its innovative team of scientists soon discovered that the oyster shell maximises the paint’s performance and makes it more durable.

Can white paint make my home cooler?

CRF’s oyster-enriched, thermo-reflective roof paint is applied in three layers. The first two layers make it a durable product which will last for around 20 years.

By adding the third layer, the paint is able to reflect 90 per cent of the sun’s rays away from a building.

This results in an average temperature reduction of six to seven degrees Celsius.

“Usually companies areusing ACand when they are using AC, that means that if we are lowering the temperature, we manage toreduce the AC use.

“By reducing the use, we are also dropping down the energy consumption for the AC,” Julien adds.

“So that means, when we are getting minus six, minus seven degrees Celsius we manage to demonstrate that we are getting between30 to 50 per cent less energy consumption, which is huge.”

Cool Roof France has already painted many shop, hospital and office roofs and the results are astounding.

In France, the company has worked closely with the police and government to paint the roof of a sniffer dog handling unit. The ambient temperature of the building was reduced by 10 degrees Celsius.

Last year, schools across Europe wereforced to close because it was too hotfor the children to be inside.

“We shouldn’t fall into this kind of situation,” Julien says.

“We have 1 billion AC (air conditioning units) today. We estimate that we may get 5 billion in 2050.AC is a solution that is making some cold inside the building by making some hot outside.So we are all impacted by this kind of crazy solution.

“Today with a white paint, this is super smart and so easy to implement.”

Can I paint my own roof white with Cool Roof France?

Currently, Cool Roof France mainly works with businesses, schools and hospitals to reduce the temperature inside buildings filled with hundreds of people.

Its staff are able to paint the roof of an office building much quicker than the same area across multiple homes.

By painting many large roof areas white in an urban environment it helps to fight against theurban heat island effect. This is whencities suffer from much higher temperaturesas the heat is contained by tall buildings and large amounts of asphalt. Cooling down bigger buildings can help reduce the overall temperature of a city or town.

But fear not, if you do like the idea of a white roof for your home (and have a love of DIY), CRF also sells its thermo-reflective roof paint via its site.

Using white paint for good around the world

With every building they paint, Cool Roof France monitors and evaluates its product’s performance. It is constantly innovating when it comes to paint.

The company also uses 10 per cent of its profits to help fund projects to support people living in heat vulnerable areas.

“Last year we went to Senegal, painting 30,000 square metres of buildings, schools, hospitals, individual houses and just to help people because this is part of our DNA,” says Julien.

“We just want to make sure that we are going beyond because today we are all suffering from thesedaily heatwaves.”

FIRST LOOK FCBS completes makeover of world’s first iron-framed building

Feilden Clegg Bradley Studios has adapted the Grade I-listed Shrewsbury Flaxmill Maltings into a £28 million social enterprise hub for Historic England after first being engaged on the project nearly 20 years ago

The Grade I-listed Shrewsbury Flaxmill Maltings was built in 1797 and was the world’s first iron-framed building, a technology developed to give better fire protection.

For nearly a century the site operated as a steam-powered flax mill and was later converted into maltings. During the Second World War the site was used as a temporary military barracks. Following the closure of the maltings in 1987, the future of the site was uncertain before it was bought by Historic England in 2005.

Historic England made it a flagship heritage regeneration project and the former maltings has been gently adapted into a workspace, leisure destination and social enterprise hub.

The project has also introduced a new ground-floor teaching space, which tells the story of the mill’s role in the industrial revolution and world architecture, alongside a café. Above, four floors of offices provide workspaces for 360 people, circulation and meeting space within the former kiln for commercial tenants, as well as access for visitor tours to the restored Jubilee Tower.

The cast iron frame, which had suffered cracking due to settlement and was under-engineered to today’s standards, has been reinforced by strengthening the masonry around the existing iron to enable it to act as an alternative load path in the event of failure. The entire frame has been put back to work through the addition of a hidden steel grillage and six new columns at ground floor level.

Putting the building back to work required comprehensive repairs to the existing fabric and insertion of new core facilities. A light-touch conservation approach was employed to preserve its character.

The pyramidal Malt Kiln, which has many level changes internally, has been converted into a new entrance. This has been left unheated to reduce energy use.

A total of 110 former windows have been reopened. This move, and refitting with new metal windows with high-performance solar glazing, reintroduces natural light and ventilation.

Thermal upgrading of the existing solid masonry walls was researched through on-site trials and hygrothermal modelling. As a result, wood fibre insulation was used to reduce heating costs.

The name ‘Shrewsbury Flaxmill Maltings’, painted in 2m-high lettering across 50m of the principal elevation, was chosen by the community following local consultations.

A heritage skills programme was delivered during the construction works, using the site as a space for learning.

Feilden Clegg Bradley Studios has been working on the project as strategic advisers and architect to Historic England and Shropshire Council since 2003. The scheme won initial planning in 2010. In 2012, the redevelopment (initially costing £52 million) won Heritage Lottery Fund backing.

Client’s view
The commitment, design creativity and attention to detail from FCBS has been impressive throughout the project. Working in close collaboration with Historic England, FCBS has delivered a fine, conservation-led solution. There is now a real sense of pride, and a positive future ahead.
Duncan Wilson, chief executive, Historic England
