Barr Surfacing & Civil Engineering has put to work its new Dynapac SD2550C tracked paver for use on projects across southwest Scotland.

Barr is using the machine on the A75 Hardgrove upgrade project laying 10,000m3 of cement bound granular mixtures (CBGM).

The paver was bought especially for this contract and to take the company into the CBGM and roller compacted concrete (RCC) markets. The SD2550C , coupled with a new 120s Rapidmix concrete plant, enables Barr to work in both of these markets.

Features of the SD2550C tracked paver include a safe impact system, integrated levelling, a sliding cabin deck and an energy-saving motor.

In addition to the large tracked paver, Barr also purchased two CC1200 tandem asphalt rollers. These are designed to be suitable for use in urban areas, with low noise, good visibility, easy operation, simple servicing and a 1200mm drum width.

Barr director Colin Morrow said: “The paver is performing well and producing a product to an excellent tolerance.”

He added: “We chose the Dynapac paver as it offers good value for money while offering all the essentials required to lay both coated and composite payments. We chose the tracked paver over the wheeled version for its ability to lay composite payments to greater depths and widths. Dynapac have provided strong service and an ability to respond quickly to our needs.”

Dynapac has been part of the Atlas Copco group since 2007 but Dynapac remains as the product name.

Delay to $62bn rail project catches HK government by surprise Completion of the HK$62.4bn (£4.8bn) Hong Kong section of Guangzhou-Shenzhen-Hong Kong Express Rail Link has been postponed by nearly a year due to construction delays including severe flood damage to a TBM.]]> Wed, 16 Apr 2014 18:03:37 +0100 http://www.theconstructionindex.co.uk/news/view/delay-to-64bn-rail-project-catches-hk-government-by-surprise http://www.theconstructionindex.co.uk/news/view/delay-to-64bn-rail-project-catches-hk-government-by-surprise

Completion of the HK$62.4bn (£4.8bn) Hong Kong section of Guangzhou-Shenzhen-Hong Kong Express Rail Link has been postponed by nearly a year due to construction delays including severe flood damage to a TBM.

Hong Kong’s transport secretary Professor Anthony Cheung said he was surprised and disappointed to learn of the situation. “Over the last weekend, I was informed by the chairman and the chief executive officer of the MTR Corporation that based on the latest assessment of the progress of the construction works, the project will be subject to some delay,” he said.

Construction started in 2010 and was due for completion next year, followed by up to nine months of testing. The project's completion has been pushed to 2016, with the line now expected to be ready for operation in 2017.

“The Express Rail Link project is a very large undertaking and immensely complex. Since construction began, we have been presented with numerous challenges which have put pressure on our schedule,” said TC Chew, projects director of MTR Corporation. “We have been very focused on catching up through fine-tuning designs and adjusting the construction works but this latest situation with the TBM makes it clear that completion of the project by 2015 is not achievable.”

During the 'black' rainstorm on 30 March 2014, a section of tunnel in Yuen Long connecting Tsat Sing Kong and Tai Kong Po was flooded when heavy rain washed soil and debris into the work site, blocking the surface drains. As a result, flood waters found their way into the partially bored tunnel where the TBM was located. After clearing the site, the MTR project team, the contractor and TBM manufacturer conducted detailed inspection of the TBM to assess the extent of the damage.

Their findings have concluded that substantial repair work is required, particularly complete replacement of the electronic components, before the TBM can become functional again. Further studies are being carried out to determine whether the TBM should be repaired or if an alternative method should be used to finish excavating the remaining tunnel section. The current assessment is a prolonged delay of up to nine months in the construction programme.

There are two other critical locations where the challenges are of particular concern. One is the extremely difficult ground condition at the West Kowloon Terminus site. The underground rock strata sitting at a higher than expected level is requiring more time to excavate. But progress has also been hindered by boulders and uncharted utilities that had to be negotiated during the excavation process. The second critical challenge involves the complex geology at the cross-boundary section of the tunnels under the protected wetland area. As marble caverns are known to be located in the zone, tunnel boring work have to proceed with extreme care and any unforeseen circumstances will have to be dealt with as they surface.

“And it will not be possible for the works to be completed in 2015. I have to say I was totally caught by surprise by such information, and obviously I felt very disappointed and deeply concerned about the delay," said Cheung. So I've asked the Corporation to provide me with a full assessment report on the progress of the construction work as soon as possible. Separately, I've asked the director of highways to conduct an independent review and assessment of the project progress.”

Amey's patchers fix potholes in two-minute drive-by Highway maintenance contractor Amey has invested in a pair of Roadmaster velocity patchers that can fix potholes in just two minutes.]]> Thu, 17 Apr 2014 07:48:02 +0100 http://www.theconstructionindex.co.uk/news/view/ameys-patchers-fix-potholes-in-two-minute-drive-by http://www.theconstructionindex.co.uk/news/view/ameys-patchers-fix-potholes-in-two-minute-drive-by

Highway maintenance contractor Amey has invested in a pair of Roadmaster velocity patchers that can fix potholes in just two minutes.

Amey is rolling out its new road maintenance vehicles on its two Highways Agency asset support contracts in East Anglia (ASC Area 6) and the East of England (ASC Area 8), which started this month.

The road patcher machines have been custom-built for Amey by Irish manufacturer Archway Products. can be fully controlled from the cab.

The Roadmaster is built on an 18-tonne single-axle Volvo truck with an automatic transmission. It is fitted with an elongated hopper to store chips and a container to store binder. It is also fitted with a hydraulically controlled articulated boom which, when not in use, folds across the front of the truck for safer transport.

Archway says that the Roadmaster delivers significantly lower cost per tonne compared to both traditional and other velocity patching methods. The capacity of the Roadmaster allows for a full day of operation – up to 7 tonnes per load of chips and two loads of chips per day.

Amey says that the machine can fill potholes in just two minutes, rather than the hour that conventional methods can take. This temporary reinstatement should be good for at least 12 months, it says.

The patchers will become part of a ‘find and fix’ assessment process whereby Amey carries out inspections of trunk roads and motorways with the vehicle with a pot hole being fixed rapidly once the pothole is reached. This can usually be carried out without the need for traffic management. The driver just extends the robotic arm from the cab over the pothole and fills it with material to fix the hole. The patcher can then move onto another location as needed.

 

 

The patchers are the major part of a £500,000 investment in new road maintenance vehicles for Amey. It has also bought a Swedish-made Brodd Europa high-speed sweeper, which has not been seen in the UK before. Thsi vehicle has a unit that is towed behind a tipper and can sweep at 20km/hour.

It will allow the road network to be swept more regularly, improving both its condition and road-user safety with less deterioration and surface flooding of the roads, Amey says.

Amey business director Margaret Seear said: “Things like potholes can be a real headache for drivers and we are pleased to provide an efficient and cost-effective solution that has real benefits for our customer, our employees and road users.”

Under the five-year contract for Area 6 Amey will be responsible for improving and maintaining routes through Norfolk, Suffolk, Essex and parts of Cambridgeshire. Area 8 covers Cambridgeshire, Hertfordshire, Bedfordshire and Milton Keynes.

The contracts, both worth up to £200m over five years, extend beyond routine maintenance to: scheme identification, value management, design and construction of schemes up to £5m; and design and management of schemes in excess of £5m.

New paver from Bomag A new 19-tonne class wheeled paver has been brought out by Bomag.]]> Tue, 15 Apr 2014 07:34:48 +0100 http://www.theconstructionindex.co.uk/news/view/new-paver-from-bomag http://www.theconstructionindex.co.uk/news/view/new-paver-from-bomag

A new 19-tonne class wheeled paver has been brought out by Bomag.

It is available for sale from next month and can be seen at the Hillhead exhibition in June.

The Bomag BF 600 P-2 has a maximum output of 600 tonnes per hour and a maximum paving width of 8m with the S500 screed.

It is powered by a Mercedes MTU 116 kW Tier 4 final engine and has an integrated Ecomode engine management system that matches power to demand reducing fuel consumption and exhaust emissions. A hydraulically powered water radiator fan automatically adapts the cooling power to demand, saving fuel.

The new S500 screed has a Magmalife electric heating system that Bomag says reduces costs and increases safety. It heats up in 20 to 30 minutes (depending on screed width and ambient temperature). This is a time saving of up to 25% compared to conventional systems, thanks to the better heat conductivity of aluminium. The aluminium plates ensure very even heat distribution across the full smoothing plate, even with extensions fitted, for a fine surface finish, Bomag says.

As well as the new screed, the BF 600 P-2 also has a large diameter auger for better material distribution, even at wide paving widths. The design avoids mix segregation and improves output, the manufacturer claims. To improve material transfer from truck to paver Bomag has designed adjustable bumper rollers that allow shock-free ‘docking’ of the truck. The bumper rollers can, as an option, be controlled hydraulically from the control stand. The rollers can be adjusted to different truck lengths and the shock absorbers and integrated rocker ensure smooth material transfer.

The operator’s platform on the BF 600 P-2 has the Sideview system, in which the seat and operating console form a single unit that can be adjusted in a variety of ways. The control stand can be extended sideways for a maximum overhang of 600mm. In contrast to conventional road finishers, the roof always protects the operator from the weather.

Bomag (GB) managing director Alan Batty said: “The machine represents a good step forward in terms of safety and productivity and operational efficiency. With construction on the up customers now have a viable alternative in the paving market.”

TBM Jessica takes to London’s streets Crossrail tunnelling machine Jessica has completed her latest journey through east London, but this time above ground on on the back of a lorry.]]> Fri, 11 Apr 2014 08:20:18 +0100 http://www.theconstructionindex.co.uk/news/view/tbm-jessica-takes-to-londons-streets http://www.theconstructionindex.co.uk/news/view/tbm-jessica-takes-to-londons-streets

Crossrail tunnelling machine Jessica has completed her latest journey through east London, but this time above ground on on the back of a lorry.

Two months after completing her 2.7km tunnel drive from Pudding Mill Lane to one of Europe’s largest mined caverns at Stepney Green, tunnel boring machine (TBM) Jessica made a 5km journey to her next launch point at the project’s eastern tunnel’s Limmo Peninsula site at Canning Town.

To make the trip, Jessica was dismantled, lifted out in pieces by crane, loaded onto heavy load-carrying flatbeds and transported from Stepney by road in a series of carefully managed operations.

This week, her 7.1m-diameter cutterhead and 65t shield were driven through the streets and through the Limehouse Link before being unloaded at Limmo Peninsula to be re-assembled and put back to work constructing the final Crossrail tunnels between Limmo and Victoria Dock Portal.

Dragados Sisk Joint Venture, the contractor constructing Crossrail's eastern running tunnels, has spent several months working with the Metropolitan Police and local authorities to plan the route through the heart of east London.

Wacker Neuson introduces new asphalt roller Wacker Neuson has launched the RD27, a new articulated asphalt joint roller available in two versions.]]> Thu, 10 Apr 2014 08:45:24 +0100 http://www.theconstructionindex.co.uk/news/view/wacker-neuson-introduces-new-asphalt-roller http://www.theconstructionindex.co.uk/news/view/wacker-neuson-introduces-new-asphalt-roller

Wacker Neuson has launched the RD27, a new articulated asphalt joint roller available in two versions.

The company said that advantages include a detailed control panel for a quick overview of all functions as well as a multi-function lever for controlling the vibration options and the water supply with one hand. The compact design without a lateral overhang provides for more flexibility in use, which also makes work in the edge regions possible. The RD27 has a turning radius of 3.6m allowing flexible use in limited space.

Another advantage claimed for the roller is the option to switch between a low and high compaction force. The low centrifugal force is optimal for asphalt compaction while the high level is ideal for the compaction of granular materials. The contractor therefore only requires one machine for the compaction of various subsoils, said Wacker Neuson.

The vibratory roller RD27 is available in two versions. The base variant has forward and backward folding roll-over protective structure and anergonomic driver's seat. The second version additionally offers a central lifting point for the simple transfer of the roller, a left-sided armrest, drum-edge lighting, and a fold-down scraper bar, as well as an optional automatic vibration connection and water cut-off.

North East contractor buys JCB loaders and excavators Owen Pugh Group has bought two JCB 457 wheeled loading shovels for handling aggregates at its quarry in Whitburn, near Sunderland.]]> Thu, 10 Apr 2014 09:37:47 +0100 http://www.theconstructionindex.co.uk/news/view/north-east-contractor-buys-jcb-loaders-and-excavators http://www.theconstructionindex.co.uk/news/view/north-east-contractor-buys-jcb-loaders-and-excavators

Owen Pugh Group has bought two JCB 457 wheeled loading shovels for handling aggregates at its quarry in Whitburn, near Sunderland.

The company also purchased seven JCB tracked excavators - one JS130, two JS160, three JS220 and a JS260 model - in the same deal. These will be used for earthmoving, demolition and general works by the Owen Pugh Contracts team.

The two new JCB 457 wheeled loading shovels are operating at Marsden Quarry - on behalf of the Owen Pugh Aggregates division - loading quarried materials onto vehicles leaving the site.

The quarry provides a range of primary and recycled construction aggregates, including type 1 sub-base, pipe beddings and clean stone that supply markets throughout the north east of England.

Andy Mountford, general manager at Owen Pugh Aggregates, said: “The two new loading shovels at Marsden Quarry have directly replaced longstanding JCB equipment which has performed admirably for us over the years. We’re already seeing a positive impact on productivity as a result of the new machines, and as they boast fuel-efficient Tier 4i engines, we expect that over time we’ll  see a positive impact on fuel costs too.”

Paul Cockburn, general manager of Owen Pugh & Co Ltd, who oversaw the purchase of the new plant machinery, added: “ It’s important for us to work with recognised leading industry brands which our customers know and trust.  The excellent customer service and the parts and service back-up from Scot JCB also played a key part in our decision.”

The JCB 457 wheeled loading shovels are powered by an 8.9 litre engine delivering 186kW of power, an increase of 16% on the previous model. With a variable geometry turbocharger, high-pressure common rail fuel injection and a diesel oxidation catalyst with diesel particulate filter (DPF), this engine also provides an 18% increase in torque while meeting requirements of the EU Stage IIIB (EPA Tier 4 Interim) emissions regulations.

Hitachi introduces new wheeled loader Hitachi has launched the ZW180-5 wheeled loader, which has a maintenance-free diesel oxidation catalyst (DOC) system and boasts up to 10% better fuel consumption than the previous model.]]> Wed, 09 Apr 2014 08:14:15 +0100 http://www.theconstructionindex.co.uk/news/view/hitachi-introduces-new-wheeled-loader http://www.theconstructionindex.co.uk/news/view/hitachi-introduces-new-wheeled-loader

Hitachi has launched the ZW180-5 wheeled loader, which has a maintenance-free diesel oxidation catalyst (DOC) system and boasts up to 10% better fuel consumption than the previous model.

The 6.7-litre six-cylinder water-cooled turbo engine is designed to contribute to high productivity levels by enabling a powerful digging performance and high travel speeds. The ZW180-5 DOC reduces particulate matter from the engine exhaust without the need for a diesel particulate filter. A chemical reaction occurs at normal system temperatures, allowing a reduction of particulate matter in the exhaust without compromising performance. Fuel consumption is reduced by up to 10% compared to the previous model, thanks to the five-gear transmission and the new fully electronic controlled engine, which combines a high-pressure common rail system and the DOC.

The machine has two simple work modes, suitable for particular tasks. In standard mode, the engine speed is controlled, which allows for efficient acceleration during loading, regular operations and travelling on level terrain. The P mode is useful when greater traction force is required for heavy-duty excavation and travelling quickly uphill.

The ZW180-5 also has a new clutch cut-off system, which controls the timing of the clutch for smooth operation when loading, regardless of the terrain. When travelling at high speed on flat terrain, the clutch can be released early so the wheel loader slows down smoothly by applying the brake pedal. When travelling slowly uphill, the clutch is released by pressing the pedal firmly to allow for easy unloading.

Further ways to minimise fuel consumption are using the eco display, which shows the operator when the wheel loader is operating economically in eco drive; and the optional auto-engine shutdown, which avoids fuel wastage while the wheel loader is long idling.

In the cab, the heated air-suspension seat can slide further back, providing more legroom. The tilting telescopic pop-up steering column has also been repositioned to create additional space.

To enhance safety on the job site, the ZW180-5 offers greater visibility from the operator’s seat thanks to a pillar-less windshield, optional rear-view camera and large sun visor. The counterweight is also now visible from both sides of the machine.

Hitachi introduces new hybrid Zaxis Hitachi has introduced into Europe the first of a new generation of excavators, the ZH210LC-5 hybrid.]]> Mon, 07 Apr 2014 08:39:25 +0100 http://www.theconstructionindex.co.uk/news/view/hitachi-introduces-new-hybrid-zaxis http://www.theconstructionindex.co.uk/news/view/hitachi-introduces-new-hybrid-zaxis

Hitachi has introduced into Europe the first of a new generation of excavators, the ZH210LC-5 hybrid.

The latest Zaxis-5 model has been designed to produce fewer emissions and use less fuel than conventional models.

The ZH210LC-5 hybrid incorporates the company’s latest technologies adopted from hydraulic, electric and battery-powered excavators. The resulting Trias HX system, which reduces fuel consumption and CO2 by up to 31%.

According to the company, the new ZH210LC-5 hybrid excavator will provide energy-saving performance, but without compromising on power, speed or ease of operation. The combination of a proven hydraulic motor and an eco-friendly electric motor enables it to provide the same high levels of efficiency and smooth swing motion as all Zaxis-5 hydraulic models, said Hitachi.

The hybrid system incorporates a swing motor that converts energy generated during swing braking into electrical energy. This is transferred via the power control unit and stored in the capacitor unit, before being used to help the engine accelerate and move the upper structure.

The Trias hydraulic system employs a three-pump/three-control valve system, designed to result in greater accuracy and to reduce pressure-loss. The ZH210LC-5 also has an electric power-assist system that comes into force for small swing operations. It uses energy from electric swing motors to carry out such movements, further reducing the machine’s fuel consumption.

In addition, the ZH210LC-5 has been designed with a monitoring system, which highlights fuel consumption and energy usage on an average hourly and daily basis. This gives the operator an accurate indication of the machine’s efficiency and encourages greater awareness of economic operating techniques.

Prior to launch, the ZH210LC-5 hybrid excavator underwent a rigorous winter test in the Arctic Circle under the supervision of Finnish contractor Maansiirtoliike Kemppe Oy. It used the machine for earthmoving and loading trucks from January until March 2014 on a road construction project in Rovaniemi alongside its existing fleet of conventional medium Zaxis-3 and -5 excavators.

In freezing temperatures that plummeted to -30°C, the machine was tested by experienced operator Kari Saraniemi. “The swing motion on the hybrid excavator means that it is even more smooth and precise than a conventional machine,” he said. “In addition, it is less noisy in the cab and the fuel consumption is excellent.”

Crossrail’s tunnelling marathon is now three-quarters complete following the breakthrough at Whitechapel by tunnel boring machine Victoria.

More than 32km of tunnelling has now been carried out and more than 2.5 million tonnes of earth removed.

The 150m-long machine is named after Queen Victoria and began her journey at Limmo Peninsula in east London at the end of 2012. She broke into the underground space at Whitechapel where work is taking place 35m below the surface to create over a kilometre of new platform and passenger tunnels for the new Crossrail station.

Tunnelling will continue during the second half of 2014 but the project’s focus will begin to shift to fitting out the stations and tunnels.

Mayor of London, Boris Johnson, said: "With three quarters of tunnelling complete, we're tantalisingly close to finishing what is without doubt a monumental feat of engineering. It's quite remarkable what the Crossrail team has achieved so far and we now look forward to the next exciting stage of the project - the fitting out of the Crossrail stations of the future."

Demolition of the Red Road tower blocks is seen as a bold and dramatic statement of intent from a city focused on regeneration.

The blow-down of five of the six remaining blocks, at one time the tallest residential structures in Europe, will take just 15 seconds and is claimed to be the biggest demolition of its kind ever seen in Europe.

This event will be beamed live into Celtic Park via a 100 metre-wide screen occupying the entire south stand of the stadium. It will form part of the opening ceremony, the curtain raiser to the largest sporting and cultural event Scotland has ever hosted.

An estimated television audience of 1.5 billion people around the world will see the 30-storey blocks fall to the ground, transforming the city’s skyline.

The blocks, owned by Glasgow Housing Association (GHA), were originally due to be demolished over the next two years. However GHA was keen to explore the possibility of bringing five down at once to minimise the number of times residents had to be evacuated. One block is currently used to house asylum seekers and will come down later.

The opportunity presented itself to bring the five blocks down during the Commonwealth Games and Glasgow City Council, Glasgow 2014, GHA and demolition contractor Safedem have been collaborating on bringing the two projects together.

Safety will be paramount as the blocks are demolished under strictly controlled conditions using more than 1,250kg of explosives. Safedem successfully brought down two of the Red Road blocks in 2012 and 2013. The blow-down will only take place during the Opening Ceremony if and when it is safe to do so.

Councillor Gordon Matheson, leader of Glasgow City Council, said: “The Opening Ceremony will be the moment when we welcome the world to Glasgow. It will be a ceremony like no other, showcasing our city’s unique style and personality and with our people and communities at its very heart. We are going to wow the world, with the demolition of the Red Road flats set to play a starring role.

“Red Road has an iconic place in Glasgow’s history, having been home to thousands of families and dominating the city’s skyline for decades. Their demolition will all but mark the end of high-rise living in the area and is symbolic of the changing face of Glasgow, not least in terms of our preparations for the Games.”

Built between 1964 and 1969 on the site of a former cabbage patch, Red Road was constructed to address the Glasgow’s growing housing needs and once provided accommodation for almost 5,000 people. Early residents revelled in the clean modern design and facilities such as central heating and a bathroom, which offered vast improvements from the slum tenements that many were moving from.

Embassy Demolition adds five Volvo machines Embassy Demolition has added four new Volvo ED220D excavators along with a high-reach demolition rig.]]> Fri, 04 Apr 2014 08:14:27 +0100 http://www.theconstructionindex.co.uk/news/view/embassy-demolition-adds-five-volvo-machines http://www.theconstructionindex.co.uk/news/view/embassy-demolition-adds-five-volvo-machines

Embassy Demolition has added four new Volvo ED220D excavators along with a high-reach demolition rig.

The bespoke three piece demolition rig is mounted on a Volvo EC480D giving a maximum pin height of 26m and a forward reach of 14m. The machine can, if needed, be converted quickly back to standard backacter thanks to its modular boom joint.

The Edmonton-based company’s fleet of crawler machines is now virtually 100% Volvo. Embassy Demolition specialises in demolition and recycling for projects covering Greater London and the Home Counties. “It’s the build quality and reliability we like about the Volvo machines,” said managing Director Jim O’Doherty  “They are robust and well specified for this sort of application.” Volvo’s level of after-market support is just as important to his operation with all of his Volvo equipment being covered by Volvo’s Blue Customer support agreements. Under this arrangement all his Volvo machines are serviced and maintained by qualified Volvo service engineers including regular inspections, oil sampling and analysis and comprehensive, proactive reports to maximise machine productivity with the aim of enhancing residual values.”

The four new Volvo EC220D machines have been equipped with falling object guarding as well as additional third hydraulic service lines to handle a variety of demolition attachments. Hammer/shear and quick fit hydraulics are provided as standard. “Equipping the machines this way means we can have full flexibility for the contracts we are undertaking which can be anything from demolition to muck shifting, material or waste rehandling,” says Jim O’Doherty.

The EC220D has Volvo’s Stage IIIB D6 engine, delivering 175hp (129kW) of power and 849Nm of torque, coupled to an improved hydraulic system with larger pumps which in turn significantly improves hourly fuel consumption with shorter cycle times.

The EC480D supplied to Embassy Demolition has a bespoke three piece demolition rig designed and manufactured by Messrs Kocurek of Ispwich. It replaces an older EC460B model. It is capable of handling a tool weight of 2500kgs. At the heart of the machine a Stage IIIB V-Act 13 litre engine develops 348 nett hp and is matched to a hydraulic system with an automatic sensing mode. The equipment features a hydraulic modular joint which enables the machine to be fitted with either ultra-high-reach demolition equipment or a straight boom arrangement or to operate as a standard backacter for digging duties.

New trucks help cut gas pipe repair times TT-UK/RSP has worked with Hitachi Capital Commercial Vehicle Solutions and National Grid to introduce six 12t Mercedes vehicles that combine coring and suction excavation technologies.]]> Thu, 03 Apr 2014 07:47:58 +0100 http://www.theconstructionindex.co.uk/news/view/new-trucks-help-cut-gas-pipe-repair-times http://www.theconstructionindex.co.uk/news/view/new-trucks-help-cut-gas-pipe-repair-times

TT-UK/RSP has worked with Hitachi Capital Commercial Vehicle Solutions and National Grid to introduce six 12t Mercedes vehicles that combine coring and suction excavation technologies.

The trucks combine the capability of two trucks into one to reduce roadside repair times with keyhole repair technology. On jobs where the technology can be used staff no longer need to enter trenches to carry out repairs, so are now personally safer, and there will be fewer large open excavations by the roadside.

The trucks combine a TT coring unit and an RSP suction excavator into one for improved gas repair times. Where keyhole technology is suitable, it can cut roadside gas repair times from five days to as little as four to five hours. This will help to reduce traffic delays, congestion and inconvenience to the public, say the developers.

The coring unit produces a ‘keyhole’ access pit measuring from 18 to 24 inches in diameter in road surfaces and footpaths made of asphalt or concrete. Using a special clamping device the core is removed from the surface in one circular piece and high powered suction excavation technology is used to remove the remaining spoil to expose the pipes. Repairs can then be completed using long-handed tools, which are able to reach down to the damaged section of the gas mains.

When the repairs are completed, the stored excavated spoil is used to refill the hole and a soil compaction supervisor (SCS) pad is placed at the base of the excavation pit. This pad provides accurate readings to a hand-held device on the surface, which manages and documents performance of the compaction activity; ensuring construction regulation standards for compaction are met. The original cored road surface is then replaced into the keyhole bore and sealed using a cement grouting sealant.

Less material now needs to be removed from the excavation and the original cored road surface can be used in the final reinstatement process. In addition, as the bored hole is circular rather than square, the hole is less likely to develop stress fractures, meaning the surface will remain intact for years to come.

Andy Martin, operations and maintenance contracts manager, National Grid said: “These specialist vehicles provide a solution to a number of challenges faced by any company when digging up the road to access utility services. By combining two vehicles, they not only speed up the repair process, but also improve safety and provide cost savings. The development process was very complex and Hitachi Capital was the perfect partner to manage the collaboration between ourselves, TT-UK and RSP in Germany.”
