Prime minister Boris Johnson has confirmed his government’s commitment to using construction to help rebuild the economy in the wake of the coronavirus crisis.
He has pledged to fund 40 new hospitals and provide large-scale investment in roads and rail projects.
A statement from Downing Street said the government was committed to an immediate £5bn package of capital investment in infrastructure projects, although some of those specifically named – such as a £1.2bn spend on schools – had been announced before, including in the Infrastructure and Project Authority’s pipeline of planned projects two weeks ago.
Johnson said a taskforce called ‘Project Speed’ would be set up to “scythe through red tape” and get projects delivered faster and hinted at changes to procurement rules to speed up appointments.
He said: “With every flood-defending culvert that we dig, with every railway station, hospital or school that we build, we will of course be tackling the next wave of this crisis by helping to create thousands of high-paid, high-skilled jobs.
“Because we know in our hearts that the furloughing cannot go on forever, and as the economy recovers we also know that the jobs that many people had in January are also not coming back or at least not in that form; we know that is the biggest and most immediate economic challenge that we face.”
A long-awaited National Infrastructure Strategy is due to be released in the autumn, Downing Street confirmed.
Balfour Beatty chief executive Leo Quinn welcomed Johnson’s speech: “The prime minister’s commitment to accelerate the UK’s long-term infrastructure pipeline is a critical factor for the country’s recovery. As well as stimulating regional and national economies, it will generate vast employment opportunities across the country and help provide our younger generations with employable skills. Without this, following the fallout from COVID-19, we could see widespread structural unemployment issues,” he said.
But Pinsent Masons infrastructure partner Jon Hart warned that the “eye-catching” commitments lack substance. He said: “The previously announced ‘pipeline’ contains a number of anomalies in respect of projects that have already been announced.
“During such an economically turbulent time, the government needs to remove uncertainty around approaches to procurement, particularly for schools and hospitals,” he added. “It will be interesting to see how tendering processes can be sped up and how the public-sector capacity gap within government for procuring schemes, when coupled with the industry’s own skills shortage, is going to be addressed.”
Federation of Master Builders chief executive Brian Berry called for the repair and maintenance sector not to be overlooked in government investment plans, and called for a VAT cut to boost that market.
UK Green Building Council chief executive Julie Hirigoyen said there needs to be more investment in specific measures to hit net-zero carbon emissions targets by 2050. She said: “The plans announced by the PM today make no reference to energy efficiency – perhaps the most urgent of all infrastructure priorities – that can create jobs right around the country, improve health and reduce costs to NHS, and increase consumer spending power by lowering energy bills.”

Air sealing is the process of restricting air movement through tiny cracks and gaps in your house. When you run heating or ventilation in your home this builds pressure. If leaks and gaps are present it can transfer conditioned air to the outside reducing efficiency. Air leakage can account for around 30% of a home’s heating costs. Air sealing prevents the loss of this conditioned air by filling in the tiny cracks and gaps.
A massive amount of energy is wasted due to the air leaking from cracks, holes and gaps in your house. This can cause several issues in your house spanning from thousands of pounds worth of repairs to medical issues. You can protect your home and family by air sealing your home. This will prevent high energy costs and create a comfortable living environment.
How Air Leakage Affects your Home?
Air leakage not only affects energy loss but also contributes to house deterioration. Obvious air leakages will be easy to spot and easily resolved; however, hidden air leakages are the root problem and can be harder to find and treat. Air that leaks must be replaced and is usually drawn in from the ground. If you don’t have an effective vapour barrier, moisture can be absorbed causing mould development, water damage or animal infestations. Moisture can enter your home using the tiniest gaps. This can aid in the damage of your home’s foundations.
How to Air Seal your Home
Depending on the location, cracks can be sealed with caulk, spray foam or weather stripping. In general, you should apply caulk to cracks no smaller than ¼ of an inch and foam for anything larger though exceptions can vary. To see whether your home needs air sealing, you should perform a check of the following areas in your home:
Exterior
Interior

Passive fire protection has been implemented since the 17th century. During the Great Fire of London, in 1666, it was proved that the wooden construction of the surrounding buildings had exacerbated the blaze contributing to the destruction of 13,200 houses, 87 churches, 52 livery company halls and obliterating the city’s infrastructure.
In response to this, King Charles II instructed for all buildings to be made of stone and for the roads to be widened. In addition to this, the government introduced the 1667 London Building Act, which, among its laws, stipulated that buildings be constructed with masonry to resist the break out of fire and prevent the spread of it. It was thought that passive fire protection was created at this time.
Whilst building regulations have improved significantly since the 17th century, there is still more work to be done to ensure that correct modern standards are correctly implemented. According to Home Office statistics, the number of fires that the Fire Services have to attend and the number of deaths that are caused by fire related incidents are increasing.
The Importance of Passive Fire Protection
Passive fire protection is built into the walls and floors of buildings to separate them into areas of manageable risk. Each area is able to prevent the spread of the fire to other areas. The idea is that the fire is contained long enough in one of these areas for occupants to evacuate from the building and for the fire brigade to fight the fire.
Most products of passive fire protection resist the fire instead of fight it. Fire resistance is achieved through constructions such as columns, walls, floors and doors. Each of these constructions will be able to resist fires in one of three ways:
All floors in a building must have components that resist fires in all three ways.
Passive Fire Protection in High Rise Residential Buildings
In the event of a fire, high rise buildings are designed to provide fire resistance that ensures the prevention of the fire spreading from where it originated. This can only be relied upon if the fire resistant materials were compliant with building regulations at the time of construction and they have been properly maintained and managed throughout their lifetime.
Due to the reliance of a high-rise building’s passive fire protection, residents are asked to stay put in the event of a fire breaking out. This is thought to be the safest option for them as the alternative may see residents leave their place of safety. Unfortunately, as we know in the recent events of Grenfell, the stay put method can only be relied upon if the appropriate passive fire protection is installed. If it isn’t, it can prove fatal as it did that day when 71 people tragically lost their lives.
Passive Fire Protection and the Law
Building owners who own property that do not pass regulations are now able to be prosecuted under the Regulatory Reform (Fire Safety) Order 2005 with some sentences going as far as being custodial. Since this came to pass, more emphasis has been placed on buildings being compliant.
Under the Buildings Regulations of England and Wales, contractors have the responsibility of handing over appropriate fire safety information to a ‘responsible person’ on completion of the building or extension of the building and it first being occupied.
Furthermore, the fire safety information given should include all design measures in appropriate detail and accurate enough so the ‘responsible person’ understands what they need to do to maintain the building safely. Building work should have been completed with adequate and proper materials sufficient for their intended use.
Despite the specific detail that these regulations go into, it is very common for built in passive fire materials, to not be compliant.
Overcoming Non-Compliance
Currently, the construction of a residential building requires the input and expertise of many fields – from architects to fire engineers to contractors. Throughout the process, the building undergoes many inspections to ensure compliance. In her interim report into the Grenfell fire, Dame Judith Hackitt acknowledged that it is therefore difficult to focus the blame for non compliance on one specific area.
She recommended in her report that there is a process change and that duty holders be tasked with ensuring compliance to a new body made up of the Health and Safety Executive, Local Authority and Fire and Rescue Professionals. This new body would be called the Joint Competent Body.
If this were adopted and implemented, it would ensure not only that more residential buildings were constructed compliantly but be able to sanction duty holders if they weren’t.
Further Incentive for Getting Things Right
Passive fire protection items that are condemned at handover or any time after fall on the responsibility of the construction company to correct. Items that are enclosed within the building can be extremely costly to repair possibly resulting in the loss of millions of pounds. This would undoubtedly bring its own financial implications.
Improvements
Small changes to attitudes and processes could reap significant improvements in passive fire protection compliance.
It is important for the sake of a building’s fire compartmentalisation that drawings are understood accurately and that architects are encouraged to be more specific of what design and materials are used.
Principal contractors should be discouraged from splitting passive fire protection into different sub-contracted packages. This method could lead to a lack of focus and could result in non-compliance.

Passive fire protection (PFP) is an essential component of structural fire protection and fire safety in a building. PFP attempts to contain a fire or prevent the fire from spreading to other parts of the building by the use of fire-resistant walls, floors and doors. A fire protection system for any building will have the following:
Any surface that is used for fire resistance is required to have a fire rating. Surfaces are rated by being fire tested where surfaces are exposed to temperatures upwards of 1100°C. Many of these tests are undertaken to test the survivability of the surfaces under realistic conditions.
A lot of Passive Fire Protection systems use many different materials in the design and construction of their systems. Most common endothermic building materials include calcium silicate board, concrete and gypsum wallboard. During fire testing, concrete slabs have been known to emit water as they boil and gypsum commonly loses all its strength when exposed to fire. The use of endothermic materials is established and proven to be sound engineering practice. The chemically bound water inside these materials sublimes. During this process, the unexposed side cannot exceed the boiling point of water. Once the hydrates are spent, the temperature on the unexposed side of an endothermic fire barrier tends to rise rapidly. Too much water can be a problem, however. Concrete slabs that are too wet, will literally explode in a fire, which is why test laboratories insist on measuring water content of concrete and mortar in fire test specimens, before running any fire tests.
PFP measures also include the use of intumescent (a substance that swells under heat exposure) or ablative materials. Any of these surfaces on their own would not be effective against exposure to fire and so need to be organised into a highly effective system that is subject to rigorous testing at multiple times.
Passive Fire Protection is designed to contain the fire in its place of origin, preventing the spread of fire and smoke for a limited amount of time. Firestops, fire walls and fire doors undergo the above-mentioned fire testing and fire resistance is usually determined in how many hours these particularly materials can contain the fire for. Their certification will provide the limitations that are present with these materials.
Unlike Active Fire Protection, Passive Fire Protection does not usually involve any form of activation or degree of motion with the exception of fire dampers and fire door closers which must move, open and shut in order to function as well as all intumescent products which rely on swelling to operate effectively.
There are mainly two types of Passive Fire Protection; intumescent and vermiculite. With vermiculite protection, the structural steel members are covered in a thick layer of hydrous phyllosilicate mineral that undergoes significant expansion when heated. This is a cheaper option to the intumescent materials but is not aesthetically pleasing. Furthermore, if the environment is corrosive, then the vermiculite is not advisable as there is a possibility of water seeping into it and will make it difficult to monitor corrosion. Intumescent fire protection is a layer of paint with a coating system along the structural steel members. The thickness of this coating depends on the steel section used. Intumescent coating is relatively low in thickness which makes it more pleasing to the eye and produces a nice finish with an anti-corrosive nature.
In the event of a fire in a building, the steel structure will eventually collapse once the steel hits its critical core temperature of around 550°C. Passive fire protection will delay this by creating a layer between the steel and the fire. This can potentially add another 2 hours to the integrity of the structure saving lives and damage to property inside the building.

NICE has published guidance, ‘Indoor air quality at home’, arguing that since we spend 90 per cent of our lives inside, poor air quality within our structures is an imminent risk to everyone’s health. The document issues recommendations to a range of stakeholders, including local authorities, healthcare professionals, and ventilation specialists.
Mr Macklin, group technical director at Elta Group, commented: “There has been significant research into the impact of bad air quality in our buildings, especially as the insulation of structures reduces levels of natural ventilation. Sick building syndrome has made an unwelcome return and the link between CO2 and concentration levels in schools is alarming.
“However, it is in homes that we spend most of our time – about 60 per cent according to NICE’s guidelines – and it is crucial that we raise awareness of the problems associated with bad domestic air quality. We are at a critical juncture and as emerging technologies equip us with means to make our homes healthier, we have a responsibility to do so.”
The guidelines emphasise the full range of this culpability, identifying opportunities for local authorities to understand the sources and symptoms of poor indoor air quality and what actions to take should they encounter it. It also contains advice for healthcare professionals, highlighting those who are most at risk and suggesting practical steps to overcome the adverse effects of pollutants.
However, it is in the building, renovating and refurbishing of homes that there is the greatest opportunity to action change.
Mr Macklin concluded: “Ventilation manufacturers must work closely with architects, designers, builders and developers to ensure homes are provided with the best solutions. From product design through to installation, the focus must be on adopting a whole-house approach to heating and ventilation, taking energy efficiency into account while striving for optimum air quality.
“As we strive to eliminate the major sources of pollutants in the outside world, we must do everything we can to make our homes a healthy sanctuary, and take an intelligent approach to implementing effective ventilation.”
