Beam Splicing on Site

Safescope Team Articles

It is a standard practice, as suggested by the CDM Principal Designers and other relevant safety professionals, that if a steel beam is of a very large size and weight, it may be spliced into two and then connected back in situ on a construction site.

This is usually the case when logistical constraints on a particular site may make transportation and placement of the beam to its intended position difficult and unsafe, due to final placement height, craneage restrictions or the beam being too heavy and large to allow for or any reasonably safe manual handling operations.

However, where the benefit of splicing and reconnecting in situ is obvious, this process can also introduce adverse safety implications when not done correctly and carefully. Not carefully designed and connected splicing can reduce the load‐bearing capacity of the beam, increase the deflection or even a complete failure.

There is another immediate concern with splicing and reconnecting onsite. If the Principal Contractor (or any other relevant contractor) piles a significant load (particularly point load) above the surface (or above the connection) of the placed beam, i.e. excessive storage of construction materials without rearising that this may take the imposed load beyond the designed capacity (some what limited by splicing), then there is real chance that the beam may deflect and cause more concern during the site work.

It will be useful for Structural Engineers to point this out to the contractors by marking it on the drawings and noting in their Designer Risk Assessments (DRAs).

Design Safety ‐ Fire Protection of Steel Frame

Safescope Team Articles

To maintain the structural integrity of the steel frame (column, beams and bracings) in case of fire (and as an important part of the fire strategy of any building), during the building operation phase, a number of methods are applied during site works to protect the steel frame. This may include application of intumescent coatings, cementitious coatings and fire resistance board, etc.

However, there is another safety consideration that could create a weak link in this fire strategy method. The above methods have a shelf life which tends to be between usually up to approximately 20 years or, in cases, longer with proper maintenance. The useful designed or expected life of a typical steel‐framed building, however, is usually 50 to 75 years or perhaps even longer.

Question then arises as to whether the fire strategy is still valid after 20 years if the fire protections measures have passed their shelf life. This is something that designers may have to take into account when specifying these products and their application on site.

Statutory Documentation on a Construction Site

Safescope Team Articles

What must be displayed or be available on site

In today's digital world, it is easy to assume “it's on the server” is good enough. But when it comes to health and safety on a construction site, statutory documentation is not just paperwork ‐ it is legal protection.

Whether you're a site manager, supervisor, or contractor, knowing what must be displayed and what must be accessible is key to staying compliant, avoiding enforcement notices, and keeping everyone safe.

Legal Requirements at a Glance

Under the Construction (Design and Management) Regulations 2015 (CDM 2015) and supporting HSE guidance, the following documents are required on site:

What MUST be displayed on site:

These documents must be physically displayed in a prominent location (e.g., site entrance, welfare cabin, site office or a site notice board ):

F10 Notification (if applicable)

• F10 Notification is required for notifiable projects (the project lasts longer than 30 working days AND has more than 20 workers working simultaneously at any one point on the project OR exceeds 500 person days).
• Must be displayed where it can be read by anyone working on site.

Health & Safety Law Poster

• Mandatory under the Health and Safety Information for Employees Regulations.
• Must be current (2014 edition or later) and completed with the relevant details

Health and Safety Policy

• The signed “statement of intent” which must be dated within 12 months

Employers Liability Insurance Certificate

• Must be up to date and displayed.

Site Rules and Induction Notices

• Should include PPE requirements, site conduct rules, and key safety contacts.
• Must be clearly displayed for all workers and visitors.

Fire and Emergency Arrangements

• Evacuation routes, assembly points, and contact details for fire marshals.
• Include site-specific fire plan or risk assessment and location of extinguishers.

Site Traffic Management Plan (where relevant)

• If plant or vehicles operate on site, display a clear traffic plan with pedestrian routes.

What can be held electronically (but must be accessible)

The following documents can be stored electronically (e.g. via tablet, cloud, app, or shared drive) as long as they are instantly accessible on request by operatives, supervisors, or visiting inspectors:

Construction Phase Plan

• CPP must be developed before works start and kept up to date.
• A hard copy is recommended on site, especially for larger or notifiable jobs.

Risk Assessments & Method Statements (RAMS)

• All current and relevant RAMS must be accessible, regularly updated and dated within 12 months.
• Site teams should know where to find them and how to access them.
• RAMS must be signed by the workers working to them.

COSHH Assessments & Material Safety Data Sheets

• Essential for any hazardous substances in use or storage.

Training and Competency Records

• CSCS cards, plant tickets, asbestos awareness training, etc.
• These can be stored electronically but must be easily produced on request.

Daily Briefings, Permits and Inspection Records

• Toolbox talks, lift plans, scaffold inspections, plant checks etc. can be held digitally.
• Must be updated regularly and shared with site teams.

Best Practice Tips

Always have a backup.

Technology can fail. We recommend keeping hard copies of the most critical documents, including the CPP, RAMS, and emergency contact info, available on site ‐ especially in remote or restricted-access areas.

Statutory documentation is not just a tick box ‐ it is a working toolkit to keep people safe. Make sure what should be seen, is visible, and what needs to be accessed, is findable.

Site Security Matters: Staying Safe and Compliant under CDM

Safescope Team Articles

Construction sites are vulnerable to theft, vandalism, and unauthorized access. Securing the site isn't just about protecting assets ‐ it's also a key requirement under the Construction (Design and Management) Regulations 2015 (CDM 2015). Here's how to stay safe and compliant:

Why Site Security is Crucial

• Protection of People: Unauthorised access can lead to injuries, especially where hazards like machinery and excavations are present.
• Safeguarding Assets: Tools, materials, and equipment are common targets for theft.
• Legal Obligation: CDM 2015 places a duty on the Principal Contractor to ensure that risks to unauthorised persons, including the general public, are minimised.

Key Security Measures to Implement

1. Secure Fencing and Access Control Erect robust perimeter fencing and control entry points with gates and security personnel.
2. Signage Display clear, visible warning signs to deter trespassers and inform workers of site hazards.
3. Lighting & CCTV Use adequate lighting and surveillance systems to deter intruders and monitor activity.
4. Storage Store valuable items in locked containers or secure areas at the end of each shift.
5. Site Inductions & Briefings Ensure all workers are aware of site security protocols during induction sessions.

Who is Responsible

Under CDM 2015, the Principal Contractor is responsible for:

• Securing the site: Taking reasonable steps to prevent unauthorised access.
• Maintaining safety: Ensuring risks are controlled, especially in areas accessible to the public.
• Monitoring compliance: Regularly reviewing security measures to ensure effectiveness.

Frequent inspections and collaboration with security specialists can help identify vulnerabilities and adapt measures as needed. Involving all site personnel in maintaining security ensures a collective effort toward a safer, more secure site.

Key elements of effective Risk Assessment and Method Statement (RAMS)

Safescope Team Articles

When we carry out Risk Assessment and Method Statement (RAMS) reviews at Safescope, we are often asked what makes a good set of RAMS.

RAMS are critical documents on any project, ensuring safe and effective work practices. Here’s a breakdown of what a good set of RAMS should include:

1. Clear Scope of Works Describe the task in detail, including its location, duration, and any specific conditions or hazards.
2. Hazard Identification List all potential hazards associated with the work which should be task specific, such as working at height, manual handling, or exposure to hazardous substances. These should come with a risk rating both before control measures are implemented (initial risk rating) and after control measures are introduced (residual risk rating) and should accompany an easy to understand risk matrix (sometimes a 5 x 5 grid with colour codes and numbers). It is helpful if hazards are ordered from higher risk to lower risk. The groups who could be harmed and how (always employees, also could be subcontractors, the general public, and others on site), must be identified.
3. Risk Control Measures Explain the steps taken to eliminate or minimise each hazard, using the hierarchy of control (elimination, substitution, engineering controls, PPE). These control measures should be reasonably practicable and specific for the task. No one expects to see 10 pages worth of control measures for each hazard. Irrelevant control measures should be removed and made specific for each task.
4. Method Statement Provide a step-by-step guide on how the task will be safely executed, detailing equipment, tools, and procedures. This should be detailed enough that the work process is explained properly but not too complicated for RAMS reviewer not to understand.
5. Roles and Responsibilities Identify who is responsible for specific aspects of the work, including supervision, task execution, and safety monitoring. The RAMS should also identify who the Principal Contractor for the works is.
6. Emergency Procedures Outline what to do in the event of an incident, including evacuation plans and emergency contact information.
7. Personal Protective Equipment (PPE) Requirements Specify the PPE needed for the task, such as hard hats, gloves, and respiratory protection. This again should be task specific.
8. Training and Competence Confirm that workers are suitably trained and competent to carry out the tasks safely.

It is also important to remember that RAMS must be dated within 12 months to be seen as valid and must also be signed by the workers who are going to be using them. Good RAMS not only help protect workers but also ensure compliance with the Health and Safety at Work Act 1974 and other regulations. Clear, concise, and well-structured RAMS promote a safer working environment and minimise risks.

Post-completion Roof Access Design - HSE Enforcement Action on Man-safe Systems

Safescope Team Articles

We recently interacted with the HSE regarding post-completion roof access and the provision of man-safe systems (fall arrest or fall restraint systems).

The HSE made it clear that for any roof access, the starting point for the designers must be the provision of collective protective measures (i.e. parapets, handrails and balustrades etc). If this is not practicable, individual protection measures such as man-safe systems may be considered, however, there must be a formal and demonstrable consideration of the collective protection measures and a credible justification for why collective protection measures have not been provided.

The HSE is now issuing legal contravention notices with a potential threat of further enforcement action against Designers and CDM Principal Designers who fail to consider the above.

The HSE position on the above is based on the following legal requirements:

• Designer duty (regulation 9(2) of the CDM Regulations) stipulates that the Designer must take into account the General Principles of Prevention (i.e. Hierarchy of controls) and Pre-construction Information (PCI) to eliminate, so far as is reasonably practicable, foreseeable risks to the health or safety of any person.
• Principal Designer duty (regulation 11(3) of the CDM Regulations) stipulates that in fulfilling the duties (as mentioned in paragraph 1 of said regulations), the CDM Principal Designer must identify and eliminate or control, so far as is reasonably practicable, foreseeable risks to the health or safety of any person.

In practical terms, the above legal requirements mean that in relation to the post-completion roof access, the following process and information should be available from Designers and CDM Principal Designers:

1. Formal identification of the risk of falls for roof access and work at height (as access required for general maintenance, services (including plant), PV panels, biodiverse roof and other relevant items), considering the height of the building and, frequency and intensity of access required.
2. Recorded details of how the above risk has been managed in the design following General Principles of Prevention (i.e. Hierarchy of controls). This requires that collective protective measures are given preference which includes the provision of parapets, handrails and balustrades etc. The collective measures significantly reduce the risk of falls and avoid individual human action, control or behaviours (hence a safer option).
3. Recorded details of plausible and reasonable formal justification for why any of the above collective protective measures have not been provided. The test for this is the application of the principle of quantum of risk and sacrifice involved.
4. Recorded details of justification for the provision of man-safe systems (fall arrest or fall restraint systems) as these are regarded as individual protection measures which rely on individual action, control and behaviour (and hence are relatively unsafe) and they are also difficult and costly to maintain for the client in the long run, as annual checks and regular maintenance of the system are required. Individuals accessing roofs are also required to have the correct equipment and be trained in working at height and the use of lanyards/harnesses etc.

The above information should be recorded in the shape of a designer risk assessment, design risk register, design risk matrix or any other suitable way to convey to the relevant parties.

Surcharge Load on Excavations

Safescope Team Articles

We carry out nearly 500 construction site health and safety inspections every year and come across different hazardous situations.

Recently, we have seen situations on sites where excavations have been left with the risk of collapse with unprotected vertical edges or soil and spoils stacked high or even existing ground cut deep on one side with the additional load of an excavator or other plant working on top of the soil or spoils stacks.

These situations create a risk of a sudden collapse potentially resulting in the risk of a serious injury or even a fatality. The risk created in these situations is explained as follows.

In plain ground conditions, any load is sustained by the underneath soil based on its bearing capacity without too much risk. It is important to note that any load is transmitted or spreads into the ground at an angle of 45% to the horizontal (as shown in Figure 1 below).

When an excavation is dug or soil is stacked with a vertical ex-posed (weak) edge/side, this vertical side, if not supported, can collapse due to the weight of the soil especially in the case of any additional (surcharge) load introduced near the excavation top edge or above the soil stack in the shape of an excavator or any other plant, load from scaffolding or piled pallets of bricks or any other materials etc (please see Figure 2).

It is important that this simple principle of load spread is understood so that measures can be taken to avoid the collapse of any excavation and soil stack etc. reducing the risk of injuries.

CDM Principal Designer vs BSA Principal Designer

Safescope Team Articles

The Building Regulations 2010 were amended in October 2023 as a result of the Building Safety Act enactment in 2022. These changes to the Building Regulations require similar to the CDM Regulations 2015, that a Principal Designer is appointed by the Client, when the building works involve more than one contractor, to ensure that the proposed design is compliant to the Building Regulations.

This new role called BSA (Building Safety Act) Principal Designer or Building Regulations Principal Designer is completely different from the existing CDM Principal Designer.

When Building Control require the details of duty holders or details of the Principal Designer they are in fact asking for the details of the BSA or Building Regulations Principal Designer, not the CDM Principal Designer.

This confusion is a result of a similar name given to two different roles. Our founding Director Dr. Khalid Bhutto, did a couple of CPD sessions for our Clients on BSA duties in October 2023. Recording of these sessions is available on YouTube, click on The BSA Duty Holders - CPD - Dr Khalid Bhutto - 6 October 2023, please.

CDM for construction projects with only one contractor

Safescope Team Articles

The CDM 2015 Regulations now apply to all construction. projects, regardless of the project size and duration, and whether the project is domestic or non-domestic.

The appointments of a Principal Contractor and Principal Designer however are not always required, depending on the number of contractors involved in the project.

If a contractor will be carrying out all works on a project themselves and will not be using any other subcontractors to carry out any part of the works then this would be classed as a one contractor project and a Principal Designer does not need to be appointed.

The appointment of a Principal Contractor is also not required however, the contractor would still be required to prepare a Construction Phase Plan for the project and, in the case of a Domestic Client Project, they would still be responsible for fulfilling the Client Duties, which include (among other duties) submitting the F10 notification to the HSE if the threshold is met.

It should be noted that most projects will involve more than one contractor. Even if there will only be one contractor on site at a time (i.e. one contractor finishes their work before the next contractor starts) or one contractor is carrying out the main bulk of the works and another contractor will only be on site for a few days/ hours for some minor works, this would still mean the project is more than one contractor.

Be aware that if the client on a non-domestic project fails to appoint a Principal Designer and/or a Principal Contractor (in writing) when more than one contractor is involved, then the Client themselves will automatically assume the legal duties of both roles.

On a domestic project if the client fails to make the appointments then the role of Principal Designer automatically falls to the main designer and the role of Principal Contractor automatically falls to the main contractor.

On our website you can find several helpful flow diagrams and charts which make it easier to understand how the CDM regulations apply in different project scenarios.

Knowledge Corner - Scaffold Inspections

Safescope Team Articles

It is the scaffold users/hirers responsibility to ensure that all scaffolding has been inspected as follows:

• Following installation/before first use
• At an interval of no more than every 7 days thereafter
• Following any circumstances liable to jeopardise the safety of the installation e.g. high winds.

All scaffolding inspection should be carried out by a competent person whose combination of knowledge, training and experience is appropriate for the type and complexity of the scaffold.

Competence may have been assessed under the CISRS or an individual may have received training in inspecting a specific type of system scaffold from a manufacturer.

A non-scaffolder who has attended a scaffold inspection course could be deemed competent to inspect a basic scaffold structure. Please refer to the CISRS guide on who is competent to inspect a scaffold.

The scaffold inspection report should note any defects or matters that could give rise to a risk to health and safety and any corrective actions taken, even when those actions are taken promptly, as this assists with the identification of any recurring problem.

Hidden killer still in your workplace

Safescope Team Articles

It is not uncommon to think that asbestos is just an issue of the past, after all, we don't use asbestos anymore and the worst forms were banned almost 40 years ago, with a final total ban 24 years ago.

A large number of those currently working in construction will not have been involved when asbestos was widely used in the same way that products are used such as plasterboard, glass fiber insulation, jointing, packing materials, vinyl flooring, decorative finishes and many more.

In the UK we used over 3,000 different types of asbestos products in the construction and maintenance sectors. Although asbestos use may now be seen as a thing of the past, the same cannot be said of the devastation and impact that it has left. Each year more than 5,000 people die in the UK from asbestos–related diseases – a figure that has continued to rise year on year for decades.

A large percentage of this death toll comes from those who have worked in the construction sector or continue to work in the construction sector, where asbestos exposures continue to occur on a daily basis. The risk of exposure to asbestos is high for anyone working on buildings being refurbished, maintained, or demolished. This risk is highest for buildings built before 2000 as the final ban did not occur until 1999.

For decades, health and safety legislation has been introduced to try and combat issues around asbestos. However, these haven't been as effective as we might have hoped – evidenced by the upward trend in the annual death toll. This in part will be due to the latency period of asbestos related health conditions. This is the lag period between being exposed and then developing one of the associated fatal diseases. Unlike many other fatal hazards, there are no instant signs to show when someone has already been exposed. You cannot see the deadly fibers when they are airborne and you won't know that you have breathed them in. The fibers are then lodged within your lungs forever. Signs of a disease won't appear for anything from 10 to even up to 60 years later.

The UK's current asbestos regulations primarily revolve around responsibilities to manage risks from asbestos containing materials (ACMs). In recent years there have been growing concerns that the UK government isn't doing enough to deal with this deadly material. As a result, in the latter quarter of 2021 the Department of Work and Pensions (DWP) launched a public inquiry into how the UK government regulates and manages asbestos. The public enquiry produced a report of its findings in late April 2022 with 10 key recommendations. The most contentious of these was the removal of all high–risk ACMs within a 40–year period. Along with a national database to highlight where all ACMs are located within public buildings.

The government issued a response that focuses predominately on existing arrangements and a need for everyone to better understand and implement their responsibilities for managing asbestos risks. However, as our increasing death toll demonstrates, existing arrangements are not effective enough and something needs to change.

In the short term this may result in more enforcement action. Those with responsibilities for identifying and managing asbestos risks must increase their knowledge and understanding. We all in the construction trade are a duty holder under the Control of Asbestos Regulations 2012, by being anyone 'who has by virtue of a contract or tenancy, an obligation of any extent in relation to the maintenance or repair of non-domestic premises, or any means of access or egress there from'. Some ACMs will need to be removed, however until such time as everyone fully understands how to assess the risks and properly identify what they must do, then we will most likely continue with our upward death trend which is why it is so important for your employees to be aware of the risks associated with asbestos.

A new asbestos management qualification is due to be launched soon aimed at those with responsibilities for managing construction and maintenance works. It is hoped this will go some way to resolve the lack of awareness.

If you are interested in getting your employees asbestos awareness trained, please visit asbestos training section on this website or contact Zac Norman on 01473 407020 for further information.

96% Construction deaths caused by Work at Height

Dr. Khalid Bhutto Articles

10 fewer construction operatives were killed whilst at work between April 2021 and March 2022 than in the previous annual period, a 25% reduction.

Despite the reduction, the construction death rate last year was the highest of any industrial sector.

Of those killed in construction 64% were employed and 36% were self employed. This is why getting working at height right is so important as it is one of the most dangerous site activities if the correct control measures are not in place.

Ensuring the correct equipment is used for each task, having all employees adequately trained, having weekly inspections on scaffolds, checking that ground conditions are inspected prior to use, ensuring rescue plans are in place, having adequate edge protection, considering the use of crash decks and ensuring toe boards are in place are just a few of the control measures that should be in place to help prevent accidents while working from height. Many of the heaviest fines are issued in the wake of working at height accidents.

Digging Safely - don't dig yourself into disaster

Dr. Khalid Bhutto Articles

Digging into the ground is a potentially dangerous activity and it seems that more and more companies are doing this in an unsafe way with electrical cable strikes increasing by 46% since the end of lockdown. On average, 70 people each year are seriously injured as a result of contact with underground electricity cables.

Digging can be much harder in urban areas such as London where there are narrow streets and lots of traffic.

HSG47‐ Avoiding Danger from Underground Services from the Health and Safety Executive (HSE) provides importance guidance and outlines three important stages of safe work during excavation:

• Planning the work
• Locating and identifying buried services
• Safe excavation

Figures show however that not everyone is following this practice with a third of construction workers failing to check for underground cables.

Here are 5 crucial tips to help you when you are going underground:

1. Research the project carefully

Designing the preferred route includes making a request for the statutory drawings for utilities. It is also crucial to take time to walk the route because this will provide a clear view of any physical challenges in the area. A visit to site can help identify risks in the work location the may not be marked on drawings. This is far more common that you might realise, as the drawings rarely keep pace with the new addition of road layout, new street furniture, pipes and cables.

2. Plan and Check

Although a CAT scanner can be used to track electrical cables, it does not provide accurate depths. If cables have been laid incorrectly this can be very dangerous to anyone working on the project. Sometimes high voltage cables have been laid at 180mm depth when the depth should have been 750mm. Planning and checking could save your life.

3. Give it enough time

Projects are always time pressed, especially when working in the city with tight deadlines. Sometimes it is not always about time, but about space. Ideally, an excavation contractor should work 500mm either side of a cable to avoid contact, but, if a cable lies very close to the edge of the allocated work area it could be tempting to lift the tarmac and see what is there. This is where accidents will happen. It is vital to take time and assess how to proceed to undertake the work safely (by extending the work zone or extending the permit). Planning ahead means that decisions are not left to a time-pressed site manager who may make bad decisions with the best intentions.

4. Pre-plan and assess proposed routes

This can highlight danger areas. Potential problems can be controlled by instructing excavation teams on how to investigate (for example, by implementing no dig-zones) clear instructions can reduce the risk of a bad decision being made.

5. Put safety first!

Everyone knows the importance of putting safety first not only for ourselves but for our colleagues and our clients. With accidents on the rise on excavation projects, it is time to put that same focus on ensuring contactors adopt robust safety standards.

New Construction Fire Safety Guidance

Dr. Khalid Bhutto Articles

The Health and Safety Executive has recently published a revised version of its fire safety in construction (HSG168) document.

Several years in the making, the latest edition contains guidance explaining the need to eliminate and/or mitigate fire risks during the design phase.

The guidance, aimed at all those working on construction projects who produce, design, develop and manage construction sites, including clients and designers, is intended to enable construction professionals to achieve good fire safety management and compliance with the Construction (Design and Management) Regulations (CDM) 2015.

It also suggests how to prevent fires from starting and ensuring people's safety if they do.

Construction fire safety needs to be managed from the earliest stages of design and procurement and needs to address the risks both to site works and to persons living or working in neighbouring buildings. This may mean reviewing particular construction methods, materials, or a site specific location to achieve effective fire risk reduction at the planning stage. Where design risk reduction is not practicable, specific mitigation measures must be identified by the designers and Principal Designer.

It is essential to consider fire measures throughout all stages of the design and procurement process and to implement them effectively during the construction phase.

The risk assessment and fire safety measures must identify high-risk activities or construction methods where fires can spread quickly, and situations where evacuation plans are complex. All risk assessments and control measures must be reviewed during the construction phase to ensure they remain suitable and sufficient during the ever changing environment and conditions.

The new guidance can be found here.

Simple and Visual CDM Duties

Dr. Khalid Bhutto Articles

In an effort to make the CDM Regulations easier to understand, we at Safescope we have prepared the following CDM Duties Guides (for Client, Designer, Principal Designer and Principal Contractor). These guides are simplified on page and visual versions to help understand different duties in an easy and visual manner. Any feedback or comments are most welcome.

A Simple Guide*to CDM 2015 Regulations

Dr. Khalid Bhutto Articles

The CDM Regulations are complex and difficult to understand, especially for those who are not involved with them on regular basis. We (Safescope) have put together the below guide to explain as simply as possible how the CDM Regulations apply on different construction projects.

Domestic Clients: domestic clients are people who have construction work carried out on their own home, or the home of a family member, which is not done as part of a business, whether for profit or not.

Non-domestic (Commercial) Clients: non-domestic (commercial) clients are people or organisations that have construction work carried out in connection with a business, whether for profit or not. For example, a client is having work carried out to their own home but is paying for the work through a company; this makes them a non-domestic client. One Contractor: means that only one contractor (including any sub-contractors) will be involved in construction work.

There are essentially four project scenarios:

1. Domestic Client Project Involving One Contractor

• Client Duties: to be fulfilled by the contractor.
• Designer Duties: to be fulfilled by the designers involved.
• Principal Designer (PD) Duties: PD appointment is not required.
• Principal Contractor (PC) Duties: PC appointment is not required.
• Construction Phase Plan (CPP): to be prepared by the contractor.
• Health and Safety File: Health and Safety File is not required.

2. Non-domestic Client Project Involving One Contractor

• Client Duties: to be fulfilled by the client.
• Designer Duties: to be fulfilled by the designers involved.
• Principal Designer (PD) Duties: PD appointment is not required.
• Principal Contractor (PC) Duties: PC appointment is not required.
• Construction Phase Plan (CPP): to be prepared by the contractor.
• Health and Safety File: Health and Safety File is not required.

3. Domestic Client Project Involving More than One Contractor

• Client Duties: to be fulfilled by the appointed PC by default or by the PD by written agreement.
• Designer Duties: to be fulfilled by the designers involved.
• Principal Designer (PD) Duties: PD appointment is required. If the client fails to appoint a PD then the designer in control of the pre-construction phase of the project automatically becomes the PD.
• Principal Contractor (PC) Duties: PC appointment is required. If the client fails to appoint a PC then the contractor in control of the construction phase of the project automatically becomes the PC.
• Pre-construction Information: to be prepared by the PD.
• Construction Phase Plan (CPP): to be prepared by the PC. Health and Safety File: to be prepared by the PD.

4. Non-domestic Client Project Involving More than One Contractor

• Client Duties: to be fulfilled by the client
• Designer Duties: to be fulfilled by the designers involved
• Principal Designer (PD) Duties: PD appointment is required. If the client fails to appoint a
• PD in writing then the client must fulfil the PD duties.
• Principal Contractor (PC) Duties: PC appointment is required. If the client fails to appoint a
• PC in writing then the clients must fulfil the PC duties.
• Pre-construction Information: to be prepared by the PD.
• Construction Phase Plan (CPP): to be prepared by the PC.
• Health and Safety File: to be prepared by the PD.

*Please note that the above guide is only a simplified version produced to clarify the basic duties. However, project specific details will be required to provide accurate information and advice on application of the CDM Regulations.

Types of Asbestos Surveys

Dr. Khalid Bhutto Articles

There appears to be some misunderstanding on type of asbestos survey required for construction work. We will explain this as follows:

There are 2 main types of asbestos surveys; a management asbestos survey and a refurbishment and demolition (RAD) asbestos survey.

A management asbestos survey is required during the normal occupation and use of a commercial building or common areas of a residential building (i.e. staircases and corridors within a block of flats) to ensure continued management of any asbestos containing materials (ACM's) in-situ. The purpose of this survey is to locate, as far as reasonably practicable, the presence and extent of any suspect ACMs in the building which could be damaged or disturbed during normal occupancy, including foreseeable maintenance and installation, and to assess their condition. A management survey can be completed using a combination of sampling ACMs and presuming ACMs or just presuming.

A refurbishment and demolition (RAD) asbestos survey is necessary when the building, or part of it, is to be upgraded, refurbished or demolished. This type of survey is used to locate and describe, as far as reasonably practicable, all ACMs in the area where the refurbishment work will take place or in the whole building if demolition is planned. The survey will be fully intrusive and involve destructive inspection, as necessary, to gain access to all areas, including those that may be difficult to reach. A refurbishment and demolition survey may also be required in other circumstances, e.g. when more intrusive maintenance and repair work will be carried out or for plant removal or dismantling. In this type of survey, asbestos is identified so that it can be removed (rather than to 'manage' it), the survey does not normally assess the condition of the asbestos, other than to indicate areas of damage or where additional asbestos debris may be present. However, where the asbestos removal may not take place for some time, the ACMs' condition will need to be assessed and the materials managed.

In a nutshell, for proposed construction works a refurbishment and demolition (RAD) asbestos survey is required.

CDM - Designer Risk Assessments

Dr. Khalid Bhutto Articles

Construction (Design and Management) Regulations (CDM) 2015 require designers to provide comprehensive information, about the risks originating from their designs, to client, principal designer, other designers, principal contractor and contractors (Regulations 8(6), 9(3)(b) and 9(4)). The above information should include design, construction and post-completion maintenance phases. For clarification, 'designers' include architects, consulting engineers, quantity surveyors, chartered surveyors, interior designers, temporary works engineers, technicians or anyone who specifies or alters a design.

It is now a well established practice to use Designer Risk Assessments (DRAs) to fulfil the above requirements. However, this information can also be included on drawings etc. We (Safescope) act as Principal Designers and receive a number of DRAs on a regular basis. Disappointingly, the majority of DRAs (almost 90%) tend to be very generic and a tick box exercise. In reality, DRAs are a great opportunity for designers to proactively inform the relevant parties about the risks that they are aware of in a project .

Residual DRAs at post completion stage are essential to inform the client about the residual risks that the client is expected to manage. Failure to provide this information can lead to injuries during post completion maintenance phase resulting in potential liability or even prosecution for designers.

However, it is also a fact that there are no good examples or effective CPD training courses available to assist the designers in writing project specific and effective DRAs. The DRA template should include design, pre-construction, construction and post completion sections and ideally should be no more than two A4 pages for a medium size project (say up to £1m). Safescope have developed 'A Practical Guidance on Designer Duties' and a 'Sample DRA' to assist designers. Please contact us to receive a free copy of the Guidance and Sample DRA.

CDM Principal Designer (PD) Role

Dr. Khalid Bhutto Articles

Who is the Principal Designer?

A Principal Designer (PD) is the designer with control over the pre-construction phase of the project. This is from very earliest stage of a project (i.e. concept design) through to planning and may extend right up to the delivery of the construction work. The PD must be appointed in writing by the Client for any construction work that involves more than one contractor.

What does the Principal Designer do?

A PD, in principle, is responsible for health and safety aspects of the design. The PD must make the Client aware of their duties under the Construction Design Management Regulations 2015 (CDM Regulations). PD then must plan, manage and monitor health and safety in the pre-construction phase, including; identifying, eliminating or controlling foreseeable risks; and ensuring Designers carry out their duties.

The PD has many more duties which are explained under Part 3 of CDM Regulations and HSE Guidance Document L153.

The Principal Designer and Domestic Client Projects!

CDM Regulations apply to all construction work including Domestic Client projects. PD duties must be fulfilled on any Domestic Client project which involves more than one contractor. A Domestic Client project is any construction work carried out purely for someone's own personal residential use and is not intended for profit and has no connection with commercial or voluntary organisations. Domestic Client duties under CDM Regulations are passed on to others who are carrying out the work on their behalf (such as main Designer and main Contractor).

The Pre-Construction Information!

The PD is responsible for ensuring that the right information reaches the right people at the right time. It should be prepared early in the project so that it can be provided to any designers and contractors as part of the tendering and procurement process. This enables those preparing bids to assess the resources they will need to allocate to perform their duties under the CDM Regulations. The amount of detail included in Pre-construction Information (PCI) should be enough to ensure that significant risks can be anticipated, focussing on those risks that could not reasonably be anticipated. Information generally required in the PCI include but not limited to; project description, key dates, contact details of project team, extent and location of existing information etc. along with safety hazards such as existing services etc . health hazards such as asbestos etc and significant design and construction hazards and Health and Safety File format etc.

Timber Frame Buildings, 16 Steps to Fire Safety

Dr. Khalid Bhutto Articles

Timber Frame Buildings and 16 Steps to Fire Safety - Principal Designer and Principal Contractor Considerations

Fire is a hazard during most construction processes and it is important that precautions are in place to both prevent fires and ensure that people can escape to safety if fire does occur. During the construction phase timber frame and structural timber buildings are more vulnerable because the precautions for the finished building are not in place. It is therefore critical that suitable and proportionate steps are taken to manage the risk from fire and that these are planned during the design and pre-construction phase, and then implemented fully during the construction process.

The Principal Designer (PD) should review and Implement steps 1 to 3

The Principal Contractor (PC) should review and implement relevant steps 4 to 16

• Step 1: Legal and insurance requirements (design stage)

• Step 2: Designing out fire risk (design stage)

• Step 3: Consideration of fire risk during construction (design stage)

• Step 4: Legal requirements (pre-site start)

• Step 5: Appointment of a Fire safety co-ordinator to take ownership of the fire risk assessment process (pre-site start)

• Step 6: Preparation of Site Fire Safety Plan (pre-site start)

• Step 7: Effective Communication and Regular Liaison (pre-site start)

• Step 8: Promoting a 'fire safe' working environment (construction phase)

• Step 9: Installation of Fire Detection and Warning systems (construction phase)

• Step 10: Establishment of Emergency Escape Routes (construction phase)

• Step 11: Site Security (construction phase)

• Step 12: Fire Safe Site Facilities (construction phase)

• Step 13: Plant, Equipment and Vehicles (construction phase)

• Step 14: Site Organisation and Tidiness (construction phase)

• Step 15: Checks, Inspections and tests throughout the construction phase (construction phase)

• Step 16: Implementation of Permits to Work system (construction phase)

CDM Client Duties

Dr. Khalid Bhutto Articles

Who is a Commercial Client?

Organisations or individuals for whom a construction project is carried out that is done as part of a business.

Who is a Domestic Client?

People who have construction work carried out on their own home (or the home of a family member) that isNOT done as part of a business.

Commercial Client Duties Summary

Make suitable arrangements for managing a project, including making sure:

• Other duty holders (including Principal Designer and Principal Contractor) are appointed as appropriate
• Sufficient time and resources are allocated
• Make sure relevant information is prepared and provided to other duty holders
• The Principal Designer and Principal Contractor carry out their duties
• Welfare facilities are provided
• HSE are notified about the construction work using F10, if threshold requirements are met.

Domestic Client Duties Summary

Though in scope of CDM, their client duties are normally transferred to:

The contractor for single contractor projects

The Principal Contractor for projects with more than one contractor

However, the domestic client can instead choose to have a written agreement with the Principal Designer to carry out the client duties.

The Domestic Client and The Principal Designer!

CDM applies to all construction work including domestic projects. As a domestic client your duties under CDM are passed on to others who are carrying out the construction work on your behalf (such as designers and contractors). If a domestic client has appointed an architect (or otherdesigner) on a project involving more than one contractor, they can ask them to manage the project and take on the client duties instead of the Principal Contractor. The designer then takes on the responsibilities of PD and must have a written agreement with the domestic client, confirming they have agreed (as PD) to take on the client duties as well as their own responsibilities.

Any designer in charge of co-ordinating and managing a project is assumed to be the PD. However, if they do not have a written agreement with the domestic client to confirm they are taking on the client duties, those duties automatically pass to the Principal Contractor.
