CIHT / Ringway Innovation Award

Winner

A-one+, Urbis Schreder and Highways England
 
winnerOn the M621, M180 and M18 in Area 12, A-one+ have delivered a series of projects to renew lighting on 24 overhead sign gantries for Highways England. The scope replaced the conventional gantry lighting with a newly developed lighting product called LED Sculp, a national first. 
 
Originally designed for use in architectural ornamental lighting, A-one+ worked in collaboration with lighting specialist Urbis Schréder to adapt the technology to work for overhead sign gantries on the strategic road network. 
 
The benefits the LED Sculp innovation has delivered on the Area 12 network has included: 
  • £889,600 of whole life cost efficiency savings 
  • 70% reduction in annual energy consumption 
  • £10,000 annual energy efficiency savings 
  • 40.8 tonnes annual carbon reduction 
  • Better quality product for customers 
  • Reduced working at height for maintenance operatives 
  • Reduced maintenance visits and network occupancy 
The way they have developed this product has now locked in the improved value to ensure the multi-benefits of Sculp can be replicated around the country. 
 
This is a true example of taking innovation from another industry, modifying it for the highways sector, and improving value by locking in safety, customer, cost efficiencies and environment benefits.
 
Judges' Comments
"The judges were very impressed by the new use of this innovative technology and its application to the highway environment. A great example of adapting a product solution to create a transformative impact on road user safety, ease of operational installation and maintenance, environmental sustainability and cost. The simplicity of the solution, its transferable potential and considerable impact, persuaded the judges of it representing an excellent example of innovation excellence, striking impact and long-term societal benefit."

Balfour Beatty, Electrokinetic Ltd and Highways England
 
A14 CambridgeIn November 2015, working for Highways England, Balfour Beatty started an £8m project to carry out a series of twenty distinct maintenance schemes on the busy A14, M11 and A428 near Cambridge.   
 
On the westbound carriageway between junctions 34 and 33 a fractured surface water drain had caused the soil in the embankment shoulder to become saturated resulting in the embankment slipping.  Conventionally, slope remediation involves significant earthmoving, large plant, intensive work on the slope and significant environmental impact with the removal of trees and vegetation, plus one of the two lanes of the A14 would need to be closed for several weeks causing substantial disruption to the road users.   
 
An alternative solution was used utilising the innovative Electrokinetic Geosynthetic (EKG) Slope Stabilisation System, developed by specialist consultant Electrokinetic Ltd. This system remediates the existing embankment fill in situ by using electro-osmosis to remove water from the ground and increase the effective stress resulting in consolidation without surcharging. Electrodes are then converted to soil nails with an electrochemically enhanced soil/nail bond. 
 
The EKG Slope Stabilisation System reduces costs, environmental impact and improves safety.
 
Judges' Comments
"Embankment repairs traditionally involve significant earthworks intervention and disruptive impact to the transport systems they typically adjoin. This entry brought a very competent and creative solution to an increasingly widespread problem for earthworks assets made more vulnerable resulting from an increasing frequency of extreme weather events. This innovative engineering solution demonstrated technical excellence, disruption minimisation and value for money."

Gammon Construction Ltd
 
Tuen Mun-Chek Lap Kok linkThe construction of numerous bridges in marine and land conditions is required to link China to Hong Kong through its newly constructed Boundary Crossing Facilities.  
On the Tuen Mun – Chek Lap Kok (TMCLK) link bridge project, construction is being facilitated by the off-site pre-construction of approximately 2,600 match-cast concrete segments to high standards of accuracy, so they may be transported to site and erected quickly to readily construct these bridges with minimum impact on the environment and Hong Kong International Airport infrastructure.  
 
“The K-Frame Family” of Bridge Deck Erection Machines 
These new machines were developed to help enhance project delivery, combining multidiscipline technologies integrated with permanent works design. 
This entry features development of the ‘K-Frame Family’ of machines currently in use on the TMCLK project. With the capacity to create eight machines providing different functions from a Parts Library, the challenges of complex bridge construction have been minimised, and reduced the need for ‘monster’ sized launching gantries that dominate project programme and costs. 
Use of hydraulics for all functions has enhanced functionality and the efficient lifting capacity to self-weight ratios. This has helped to minimise deck loading during construction, which is typically the most onerous condition experienced by a bridge during its life cycle.
 
Judges' Comments
"The judges considered this to advocate very well the creative capital of the construction industry in creating a grand and highly innovative approach to facilitate the execution of major civil engineering works. A genuinely innovative solution befitting such a project, in terms of scale and complexity."

S&C North Alliance - AmeySersa working in partnership with Network Rail
 
SC North AllianceIn September 2016, S&C North Alliance, a powerhouse partnership between AmeySersa and Network Rail, made UK rail history on the East Coast Main Line by reopening the line immediately after renewing a switches and crossings (S&C) turnout at 125mph.  
 
Expanding on these techniques, in February 2017 the team reopened the line at 125mph at Sandy South, Bedfordshire after renewing a much more technically complex track layout, consisting of three crossovers and one turnout.  
  
By harnessing innovative techniques, deploying world-first technology and by pursuing a relentless focus on right first time quality, S&C North Alliance has paved the way for making high speed handback the norm. Creating better passenger journeys, improving asset quality and reliability, while reducing whole of life costs.
 
Judges' Comments
"This entry emphasises the advancement in and use of technology in construction equipment and methods to facilitate high performance and precision outputs in demanding and complex engineering environments. In this case, to permit 125mph handback on S & C renewals within safety-critical, operational railway environments. A great example of transferable, efficient and innovative techniques to deliver sustainable customer and user benefits."
