Sign installation at Warrington

Case Study: innovation in 20mph scheme for Warrington Borough Council


Warrington Borough Council (WBC) has committed to introducing 20mph speed limits in the majority of residential roads. The project aims to improve the quality of life for all residents by giving greater ownership of streets and public spaces, as well as encouraging healthier forms of transport, such as cycling and walking, and reducing the number and severity of collisions.

Following a successful 18 month pilot, WBC undertook a comprehensive tender exercise and appointed JPCS as the installation partner for the delivery of the rollout


  • Minimising disruption to in residential areas
  • Generating cost efficiencies


To deliver the programme as efficiently and diligently as possible, without compromising on quality, the partnership considered innovative methods and approaches. JPCS recommended Groundscrew – an innovative, concrete-free foundation, which would enable significant cost and construction time reductions, whilst improving quality, safety, and environmental outcomes. WBC committed to using Groundscrew where possible, equating to approximately 50 per cent of the signs.

A cost-effective, robust alternative to traditional concrete bases, Groundscrew – which is faster and safer to install – has enabled a more efficient delivery due to the significant gains in installation times.


The Groundscrew approach has highly benefited WBC and residents, as well as demonstrating best value in terms of cost savings, quality of service, safety, end user satisfaction, and programme delivery:

  • Installation time is unbeatable, on average seven times quicker than conventional processes. The system eliminates costly, time consuming excavation and concreting, thereby increasing safety/customer satisfaction
  • Whilst the initial, estimated completion date was 2015, using Groundscrew has enabled the partnership to stay ahead of schedule, with all 20mph speed limits now expected to be implemented by August 2014 – saving almost 40% on overall project duration
  • Reducing the time spent on site has increased safety and reduced labour costs. Less time on site also means the new speed limits can be in place quickly, safely, and with as little disruption to residents as possible, bringing forward the visual impact from a lower speed restriction
  • Cost-effective solution, saving 25% on estimated costs, with over £190k saved
  • Groundscrew is also much less weather dependent, which has avoided significant delays with the recent weather – the wettest on record. With no digging, excavation, wet trades, or curing time, challenges due to weather conditions have been minimised
  • The adaptability of Groundscrew has already been demonstrated. Following feedback from residents about the positioning of some of the posts, the partnership has been able to relocate them economically, quickly, and safely – due to the flexibility of the Groundscrew foundation against concrete – therefore improving resident satisfaction. In contrast with concrete foundations, removal also generated minimal landfill requirements, leaving very little impact to the landscape
  • Maximum efficiency and minimised risk, hazard and disruption to residents/road users.

The innovative Groundscrew concept and pioneering approach to the programme has delivered benefits to all stakeholders, demonstrating the partnership’s commitment to excellence. The scheme was shortlisted in two categories at the 2014 CIHT North West Awards, being Highly Commended for Safety Project of the Year.
