EnviroHoard™

The UK’s First Net Zero Carbon
LCA Verified Hoarding System

Sustainable Construction Site Hoarding

A first for the UK construction industry, EnviroHoard™ is the first sustainable Construction Site Hoarding System to have been verified Net Zero Carbon.  This Net Zero Site Hoarding System has gone through an extensive cradle to grave Life Cycle Assessment (LCA), in accordance with the European wide standard EN 15804:2019.

Developed by Panthera Group, EnviroHoard™ is a patented Construction Site Hoarding System designed to help the industry eliminate the use of timber and plywood for the construction of site hoarding, to support their BREEAM, CEEQUAL and Considerate Constructor scoring, whilst also working towards Construction 2025, the UK Strategy for Sustainable Construction.

EnviroHoard™ is the only Net Zero Carbon Construction Site Hoarding System in the UK construction market, its panels are made from 100% post-industrial production and post-consumer waste uPVC and form part of our ‘Closed Loop’ solution.

To further support our client’s own sustainability targets, EnviroHoard™ comes with additional climate positive benefits – carbon offsetting and tree planting that can be directly attributed to the individual project.

The System

A Patent Pending, Engineered Sustainable Hoarding System for the Construction Industry

The brief was simple, to design the most sustainable and useable site hoarding system for the UK construction market.  We started by reengineering the simple concrete block that is commonly used for no-dig hoarding systems and then focused on the steel support frame; it needed to be robust, quick and easy to install – a simple yet inventive, ‘fixing free’ horizontal rail system was the goal.

The systems modular design has been developed so that it is temporary works compliant to be installed in the UK’s three wind zone regions, so whether your project is in London, or in the Yorkshire countryside, EnviroHoard™ modular design can be installed to comply TWf:2012 (Temporary Works Forum) guidance.

EnviroBlok

Our 800kg EnviroBlok is manufactured in-house and has been designed specifically to work with the EnviroHoard™ system.

A strategically positioned cast-in channel and M16 cross pin sockets allow the system to be installed on uneven ground with ease. Blocks are connected at all corners and stacked at free ends to comply with temporary work design requirements.

To meet the UK’s most severe wind zone 3, EnviroBlok can be stacked up to three high, with all blocks connecting to the steel support posts.

As you would expect, our block is low carbon and incorporates 50% Ground Granulated Blast Furnace Slag which is a sustainable cement replacement.  Using one tonne of GGBS in concrete reduces the embodied CO2 by around 900kg, compared to using one tonne of Portland Cement, and also increases its durability.

With a large slot for forklift tines and a 2.5ton rated lifting pin the block can easily and safely be moved around the site

  • Low Carbon with 50% GGBS cement replacement
  • Manufactured in-house
  • Engineered design with certified fixing and lifting points
  • Lifting slot for forklift tines or pallet truck
  • Shallowest footprint on the market for tight spaces
  • Blocks stackable 3 high and connect to post to meet UK’s 3 wind zones
  • Corner blocks connect for TW design compliance
  • Free end blocks stack and connect to post for TW design compliance
  • Unique shape and branded during pre-cast process

Support Frame

Designed to meet temporary works compliance and the demanding challenges of construction sites, the galvanized steel support framework is strong, simple and quick to install.

Adjustable upper and lower steel brackets connect the EnviroBlok to the steel support post with a simple yet effective adjustment mechanism, the system can be installed with a gradient of no more than 1:8.

Strategically positioned welded rail support brackets on the post allow horizontal levelling of the system on uneven ground.  A unique feature of the system is the ‘fixing-free’ rails – these help to increase speed of installation and, adapting and dismantling the system.

The framework can facilitate lighting and cable support brackets, can be extended to 3.0m and 3.6m high and can be used with a range of weldmesh panels to provide a no-dig temporary security mesh fence.

  • Engineered design to meet wind, notional and crowd loading
  • Adjustable brackets provide rapid levelling of the post in both axes
  • System can be installed to a gradient of up to 1:8
  • Simple, yet effective posts with strategically welded rail supports
  • Unique ‘fixing-free’ horizontal rails for ease and speed of installation

EnviroHoard™ Panels

Our panels are manufactured using post-production and post-consumer waste uPVC and have been independently stress tested.  They are reusable and provide ‘closed loop’ benefits. Panthera supply new A grade panels as standard but can offer ‘once used’ B grade panels for an even greater sustainability scoring.

Panels that reach the end of their life cycle are returned to the manufacturer where they are reprocessed back into pellet form ready to be extruded into shiny new EnviroHoard™ panels – a truly ‘closed loop’ product.

EnviroHoard™ panels can be extruded in thousands of RAL colours to support your branding and vinyl graphics can be applied directly offering a seamless visual to showcase your project and brand.

Improved manual handling as each panel weighs just 5.7kg compared to around 23kg for a sheet of plywood. The standard height is 2.4m but they can be extruded up to 7m. Panels are 500mm wide, have a tongue and groove 35mm deep profile on each edge and a 35mm deep central profile for additional strengthening profile.

  • Manufactured using post-production and post-consumer waste uPVC
  • Independently stress tested
  • Closed Loop process – end of life panels are reprocessed into new panels
  • ‘Once used’ B grade panels for even greater sustainability scoring

Sustainability

Introducing the UK’s first Net Zero Carbon Hoarding System

It is now widely accepted that we are facing a global climate crisis, and all have a part to play to halt the increase in the rise in temperature of our planet. Construction is a high impact industry on the environment and faces many sustainability challenges.  However, an increasing number of main contractors are taking leading roles in improving sustainability in construction, which has been an inspiring factor behind the development of EnviroHoard™.

We at Panthera believe it should not be only large main contractors who take on these challenges faced by the UK construction sector alone; there are also many more small and medium sized subcontractors that can make change.

To play our own small part in making smarter sustainable choices, Panthera are proud to introduce EnviroHoard™, the UK’s first Net Zero Carbon Verified Hoarding System. Each installation method has gone through an extensive cradle to grave Life Cycle Assessment (LCA), in accordance with the European wide standard EN 15804:2019. In addition to the system being Net Zero Carbon, EnviroHoard™ comes with climate positive benefits, tree planting and carbon offsetting for every metre installed – a measurable benefit that can be attributed directly to the project for improved BREEAM, Considerate Constructor and CEEQUAL scoring whilst also working towards Construction 2025, the UK Strategy for Sustainable Construction.

Net Zero Verified

EnviroHoard™ is the UK’s first Net Zero Carbon Verified sustainable hoarding system. It has gone through an extensive cradle to grave Life Cycle Assessment (LCA), in accordance with the European wide standard EN 15804:2019.

A Life Cycle Assessment considers the consumption of energy and materials, plus the release of emissions throughout the supply chain. This is taken all the way back to their extraction from the earth, transportation, material production and through their product lifetime, ending with the waste management activities. This is completed to get a more holistic perspective. For EnviroHoard™, this provides the embodied carbon footprint of producing and installing the system.

Net Zero Carbon, also known as carbon neutrality, requires a detailed carbon footprint assessment, in accordance with international standards. Once this baseline is established, the remaining embodied carbon is mitigated, through carbon offset projects around the world. The carbon offsets were from Verified Carbon Standard (VCS) and Gold Standard projects and have benefits in all 17 of the UN Sustainable Development Goals. This balances the embodied carbon emissions, down to Net Zero Carbon

For the first time, Main Contractors can now choose a Net Zero Carbon, closed loop hoarding system over timber and painted plywood hoarding. Contractors will benefit from improved BREEAM, CEEQUAL and Considerate Constructor scoring.

Climate Positive Benefits

Panthera are passionate about eliminating the use of timber in the construction of its site hoardings. Our ambition is to eliminate the use of timber and plywood in the construction of our hoardings by 2025. We do not disagree with the use of timber in construction; however, we do understand that cutting down 30-60-year-old trees to be used for temporary short-term site hoarding just doesn’t make sense.

The introduction of EnviroHoard™ supports our ambition and we are proud to have partnered with UK charity, Trees for Cities where we will be planting trees for every metre of EnviroHoard™ we install. They are the only UK charity working at a national and international scale to improve lives by planting trees in cities.

In addition to our Trees for Cities partnership, we are also proud to have teamed up with Circular Ecology who are leading environmental sustainability experts. Their Director Dr Craig Jones carried out the Life Cycle Assessment (LCA) on EnviroHoard™ and has supported our drive to being sustainability leaders in the hoarding industry.

Through our carbon offsetting programme, we will be working with Circular Ecology and supporting their own programme with Eden Projects who plant trees across locations such as Madagascar, Haiti, Nepal, Indonesia, and Mozambique. These are all nations that have been ravished by deforestation.

Temporary Works

Engineer Designed & Certified Hoarding & Fencing Systems to Comply with TWf:2012

All EnviroHoard™ and EnviroFence™ installation methods are supported by Engineer Design Drawings, Supporting Calculations and Design Check Certificates, to comply with the latest Temporary Works Forum (TWf:2012) Guidance.

We directly employ a Temporary Works Co-ordinator (TWC) who is responsible for the implementation of our temporary works procedure, as well as the direct appointment of Temporary Works Supervisors (TWSs).

Temporary site Hoarding and Fencing falls under ‘Temporary Works’, which means, “Parts of the works that allows or enables construction of, protect, support or provide access to, the permanent works and which might or might not remain in place at the completion of the works”.

As you would expect there is a robust Temporary Works Design process to follow; the below shortened process has been provided as guidance and should be followed by all parties: –

  1. Design Brief – The client must provide the hoarding contractors’ TWC with a design brief
  2. The Design – The TWC passes on the design brief to a Temporary Works Designer (TWD) who must be a ‘competent’ person to carry out the design in accordance with the design brief.
  3. Design Risk Assessment – The TWD should issue a risk assessment to supplement the safe system of work and method statement.
  4. Design Check – A Temporary Works Design Checker (TWDC) should issue a design check form as part of the design process. The independence of the design checker to the designer shall be as set out using the BS 5975.
  5. Installation – Works installed in accordance with the design, Permits to Work and Hold Points are managed by our TWS.
  6. Temporary Works Inspections – Once installed and signed off by Panthera’s TWC it is the main contractor’s responsibility to maintain Temporary Works Inspections of the hoarding structure throughout the project.

Printed Hoarding Graphics

Eco-Friendly Printed Hoarding Graphics

Panthera are proud to have partnered with award winning graphics and signage specialist, Lavastar. This partnership combines two of the industry’s leading companies; the result is that we are able to offer our clients the most comprehensive nationwide, site hoarding and custom printed hoarding service. In addition to hoarding graphics, we can also supply high quality building wraps and for housebuilders, we offer a comprehensive, and cost-effective property development signage package.

Why are EnviroHoard™ graphics eco-friendly? Unlike traditional plywood hoarding where vinyl graphics are applied to aluminium sheet known as di-bond, EnviroHoard™ graphics are applied directly to the face of the hoarding. This removes the need for di-bond which not only has a cost associated to it, but it is generally scrapped at the end of the project increasing the carbon embodiment of the process.  Panthera are pleased to be partnered with an industry leader who can also offer PVC free vinyl suitable for indoor and outdoor graphic applications.

EnviroHoard™ offers a near seamless and smooth hoarding to showcase your brand or promote the project – it is the perfect canvas. Unlike other systems in the market there are no large vertical joint strips that interrupt the hoarding every 1.2m; these strips greatly reduce the visual impact of the hoarding graphics and instead of a seamless eye-catching design, this type of hoarding creates a visual appearance resembling a line of individually printed posters.

Commercial Benefits

Sustainability Doesn’t Have to Cost More?

As an industry, if we are really serious about helping slow down the climate crisis, we must act now! One way we can start is by changing the mindset of how construction products and services are procured; we believe it should not always be about the initial cost, rather, that the total cost of ownership should be built into the costing analysis.

Another factor that should be taken into account when placing orders is the environmental impact – as an industry we have a responsibility to reduce the CO2 of the projects we work on. Some of the UK’s leading construction businesses are taking on these challenges and lot is being achieved but we still have a long way to go until sustainability is a key factor in the procurement process, as decisions should not be made solely on price.

Panthera are confident EnviroHoard™ offers a cost-effective and viable sustainable hoarding system, one that delivers measurable cost savings over the lifetime of the hoarding – the true cost of something is the Total Cost of Ownership (TCO).

Commercial Benefits Include:

  • Zero Maintenance – No ongoing maintenance costs
  • Modular & Reusable Design – Reduces future labour and material costs
  • Procurement Options – Purchase, Short-Term and Long-Term Contract Hire
  • Guaranteed Buy Back – Recoup money back at the end of the project
  • Reduced total cost of ownership (TCO) over the project lifecycle

EnviroHoard™ not only helps us to meet our ambitious environmental targets, it also has real practical benefits. The panels needed to sit on top of a retaining wall with a 4m drop on one side. As EnviroHoard™ is installed from the rear, it eliminated the need for a partial road closure and the hiring of aerial platforms (MEWPS) which saved traffic disruption and cost and a further benefit was that the works did not have to take place at night.
The hoarding has a clean, professional looking appearance and does not need any on-going decorating maintenance and can be easily dismantled and reinstalled across the project with no loss in its visual appearance or structural integrity.
Matthew Davis - Project Manager
Kier Construction
Firstly, the hoarding system we chose needed to be able to last for the entire project; this is because we made a conscious decision early on that a key driver across the scheme was to look for environmentally friendly alternatives. The EnviroHoard™ solution enabled us to meet that requirement perfectly.
We had been testing the product on simulated sites, but the opportunity to install in a real situation was ideal and has reaffirmed the benefits of the system. When coupled with the benefits of using a closed loop recycled solution that eliminates the use of trees, we believe EnviroHoard™ is the way forward for site hoarding solutions.
