Winvic awarded emergency bridge repair project under national highways SDF

Winvic Construction Ltd, a leading main contractor that specialises in the design and delivery of multi-sector construction and civil engineering projects, has been given its first contract within National Highways’ new Scheme Delivery Framework (SDF). Routine investigations to the M62 Ouse Bridge, located between Goole and Howden in Yorkshire – or between junctions 36 and 37 of the M62 – identified a partial failure of a joint on the eastbound carriageway. Therefore, Winvic has been appointed as one of the organisations on the SDF undertaking temporary and then permanent repairs on the structure and highway. It was discovered that increased vibration from traffic had started to damage the concrete under lane three and a bridge joint, which allows the carriageway to expand and contract with the weather. A contraflow was immediately put into place, reducing traffic on the eastbound carriage to one lane, to allow temporary works to begin, while a series of overnight road closures during the week commencing 13 June facilitated a second eastbound traffic lane to open on Saturday 18 June minimising disruption to road users. Winvic installed temporary metal bridging plates across parts of the eastbound carriageway, which enabled a further eastbound lane and the eastbound exit slip road at junction 37 to be reopened on Friday 8 July.   Winvic has employed its ‘one-team’ approach and is working closely with a number of National Highways project partners; Jacobs is designing the repairs, traffic management is being led by Amey and Winvic, along with specialist Contractor VSL, is heading the joint repair and replacement. Together the companies are currently working on the complex design process required to replace all eight joints across both carriageways towards a solution that reduces the need for full closures in the future as much as possible. Temporary bridging plates have been installed over the damaged bridge joints as a temporary mitigation measure, and a second set will be added this autumn. The two most critically damaged joints on the eastbound carriageway will be replaced by spring 2023 and the project will be fully complete in Autumn 2023. Winvic won its place on the National Highways SDF in September, along with 49 other contractors that will deliver £3.6 billion of road renewal works on England’s motorways and trunk roads over the next six years. Rob Cook, Winvic’s Director of Civils and Infrastructure, commented: “We have been working hard with National Highways and the Yorkshire North East region to mobilise the Scheme Delivery Framework since we were awarded our place on it in September, so we were able to mobilise rapidly on this project on the M62 Ouse Bridge to begin the necessary immediate temporary works. We put multiple interfaces in place with the National Highway team and the other project partners, so we could work as one-team, towards one-goal with safety as the ultimate priority. “The surfacing and bridging plate works have met programme expectations, meaning road users have been able to go back to using multiple carriageways and the programme is in place to install more plates this Autumn; while the priority always must be safety, it’s also crucial that disruptions to people’s journeys is minimised as quickly as possible and negate the need for full road closures as much as possible. Once the permanent solution has been fully designed and  fabricated, we will undertake these permanent works, facilitating the long-term safe use of the Ouse Bridge.”  Members of the public can keep up to date about the project and any related traffic disruption, by visiting https://nationalhighways.co.uk/our-work/yorkshire-and-north-east/m62-ouse-bridge/.  Phil Jepps, National Highways Programme Delivery Manager, added: “The temporary repair work around the bridge joint and the permanent replacement of all eight joints on the Ouse Bridge is a very complex project. To complete this as quickly, safely and effectively as possible, it’s important we work with outstanding partners who share our commitment to working towards the highest possible standards. We would like to thank Winvic and our other partners on the Scheme Delivery Framework for their ongoing support to keep traffic moving safely while completing the vital resurfacing and bridging plate work.” For more information on essential safety work taking place on Ouse Bridge, visit the National Highways dedicated web page for the bridge https://nationalhighways.co.uk/our-roads/yorkshire-and-north-east/m62-ouse-bridge/ or follow National Highways Yorkshire on Facebook.

Spencer Group to begin unique temporary walkway works on heritage bridge

Industry leading multi-disciplinary bridge works specialist Spencer Group has come up with a unique method to carry out essential works on an historic structure. Spencer Group is carrying out the design, construction, installation and maintenance of a temporary walkway for Grade II listed Connel Bridge, in Scotland, ahead of major deck replacement works. The walkway, which will be cantilevered off the east side of the bridge, will allow for pedestrian and cyclist access during the works to replace the entire deck, which will take place over the course of the next two years. The walkway is expected to be completed in four months, with the possibility of retaining the facility depending on a feasibility study and full public consultation. The walkway construction has been programmed to cause minimal disruption to traffic and the local community. The A828 Connel Bridge was the second largest cantilever bridge in Europe when it was built by Sir William Arrol in 1903. It links the villages of Connel and North Connel, close to Oban. Originally a railway bridge, it was used for both rail and road traffic from 1914, until the railway closed in 1966. The new steel walkway design will be in-keeping with the heritage of the bridge, with Spencer Group also self-delivering integrated street lighting. Spencer Group is carrying out the project for BEAR Scotland, a service provider in the Scottish roads maintenance sector, on behalf of the national transport agency for Scotland, Transport Scotland. The temporary walkway is part of the critical enabling works ahead of the deck replacement scheme and Spencer Group, which specialises in providing innovative solutions to complex engineering projects, is mitigating the impact the walkway works will have on traffic and the local community. Luke Fisher, Sector Lead for Bridges and Structures at Spencer Group, said: “We’re delighted to have been selected to carry out this important project, which is the latest in our growing portfolio of heritage bridge works. “During the tender process, we focused our proposals on a sympathetic walkway design and methodologies that reduced traffic management during the construction works. “Our designers proposed a traditional steel walkway design that was in-keeping with the heritage of the bridge, clamping to the existing structure where possible, to minimise invasive construction works to the bridge interface points. “A key element of the project is also to minimise the impact on local residents and traffic, both on Connel Bridge and on the A85 below. “The original design intent was to install support brackets over the side of the masonry viaducts that would require rope access for installation, meaning traffic management would have needed to be in place on the A85. “We’ve come up with an alternative design solution that mitigates this, with brackets that can be installed from the confines of the bridge parapets. In addition, we’ve developed an installation methodology that allows our teams to install the new walkway progressively from the leading edge, almost eliminating the requirement for traffic management on the bridge during the works.” Eddie Ross, BEAR Scotland’s North West Representative, said: “We appreciate the historical importance of the A828 Connel Bridge and the vital transport link it provides to local communities. “This project will allow teams to install a temporary footway on the east side of Connel Bridge, in advance of the deck replacement works which are scheduled to take place next year. The temporary walkway will maintain a route across the bridge whilst the bridge deck is replaced, as we will need to close the existing footpath and carriageway. “Alongside Transport Scotland, we are currently considering making the walkway a permanent facility and will carry out a feasibility study of the options available, which will include consultation with all key stakeholders.” Spencer Group delivers innovative engineering and construction solutions in the transport, infrastructure, materials handling, energy and industrial sectors.

Scaffolding Association concerned that 1 in 3 employers have not talked to staff about their mental health over the past year.

New research by the Advisory, Conciliation and Arbitration Service (ACAS) has found that over a third (35%) of British employers have not spoken to their staff about their mental health and wellbeing over the past year. A survey conducted on ACAS’s behalf by YouGov, asked businesses in Britain about whether they had personally talked to their staff about their mental health in the last 12 months. The poll found that: Robert Candy, Chief Executive of the Scaffolding Association said; “Businesses must do more to support employees with their mental health and wellbeing. It is inevitable that the pandemic will have exacerbated pre existing concerns. It will have also created new mental health and wellbeing issues among individuals and employees. The easiest thing a business can do is to talk with their staff, so it is concerning that over a third have not taken this basic step”. Office for National Statistics (ONS) figures show that more than 2,000 construction workers took their own lives in the UK in the decade to 2017 which is more than four times the number of construction workers killed during the course of their duties for the same period. The Scaffolding Association recently established a Health and Wellbeing Committee which aims to help employers in the sector improve the support they provide in relation to mental health and to encourage employees to talk with employers and colleagues.

New bridge is a UK first to combat risk of flooding

A new stainless steel and concrete bridge, the first of its kind in the UK, has opened to pedestrians and vehicles in Pooley Bridge, Cumbria. It replaces its 250-year-old stone predecessor, which was destroyed during severe flooding as a result of Storm Desmond in 2015. The new single-span bridge has been designed to withstand extreme weather conditions and is in keeping with its location in Ullswater on the edge of the Lake District National Park. Hanson UK worked with contractor Eric Wright Civil Engineering Ltd to create a bespoke concrete mix for the lower arch of the steel bridge, designed and constructed to provide structural strength, and also supplied and laid the asphalt to complete the project. The steelwork for the new bridge was manufactured off-site in two sections, fabricated and welded on an adjacent piece of land, where the concrete lower arch was installed to allow the whole structure to be lifted into place over the River Eamont. The high early strength concrete mix included Hanson Regen GGBS (ground granulated blastfurnace slag), a cement replacement product which enhances the durability of the concrete while adding to its sustainability credentials. It is a by-product and using it to replace one tonne of Portland cement reduces the embodied CO2 of the concrete by around 780kg. Its use in large pours also helps minimise the production of heat, reducing the risk of thermal cracking. In total 1,200 cubic metres of concrete containing Regen have been supplied by Hanson’s nearby Penrith concrete plant to create the lower arch, bridge deck, bridge abutment and walls, highway approach retaining walls and several temporary works. “Concrete supply to this project was always going to be a challenge due to the location, unique characteristics of the bridge and the tight deadline,” said Nick Graham, technical sales officer at Hanson Concrete. Technical services manager Terry Balmer added: “Our technical team was involved early in the design stage due to the complex concrete requirements, especially for the high-quality visual concrete that makes up the deck composite, and this partnership working was fundamental to the success of the project.” To complete the project, Hanson supplied 275 tonnes of asphalt from its nearby plant at Shap, which was laid by the company’s specialist contracting team. This included 130 tonnes of Tufflex, chosen for its durability and high resistance to cracking, for the surface course. In addition to the complex nature of the bridge, the final abutment work, concrete arch and composite deck – as well as the asphalt – were all supplied under the added pressure of the Covid-19 pandemic and the associated issues entailed with furloughed staff and social distancing protocols.

Centre of Excellence in Temporary Works and Construction Method Engineering

The main aims of the Centre of Excellence are to provide opportunities in Temporary Works and Construction Method Engineering, with a postgraduate course available and targeted research projects with direct industry involvement. About The Centre of Excellence comprises a large number of academic staff across engineering disciplines who are committed to addressing industry challenges associated with construction processes.  This groups has many years of experience in providing insight into practical problems and have access to state-of-the-art testing facilities that allow exploration into simple and complex problems. People Research The main aim of the Centre of Excellence is to undertake research that will support the Temporary Works Forum (TWf) in driving “long-term change and waste reduction in the way we construct”. The Centre of Excellence at City, University of London, supported by the Temporary Works Forum (TWf), have two doctoral research projects on-going, please see the descriptions below: 1. Safety of Working Platforms for Tracked Plant Formed from Construction Demolition Waste. The key design criterion for working platform design is whether it can safely support the application of an extremely high monotonic load applied eccentrically through the tracks of plant. Thus, the design criterion is stability. The BRE guide idealises this load case as load acting over an equivalent area, rectangular in plan, which lies on layered ground. The depth of the upper layer, the working platform, is determined by assuming a punch through failure mechanism in this layer and conventional bearing capacity failure in the subgrade.  Designers following this method then need to determine the appropriate angle of friction to be used in the calculation of the resistance of the platform material (construction demolition waste) to punching failure.  The aim of this approach is to provide a conservative design method given that insufficient data exists. This research is being carried out by Greta Tanghetti under the supervision of Dr Richard Goodey. 2. The strength and stability of steel reinforcement cages in their temporary state. The contributing strength of a steel reinforcement cage to that of a reinforced concrete column, beam, slab or wall is well understood.  However, the strength and stability of that same cage during its assembly, handling and whilst lifting into position prior concreting is not.  Whilst a number of guidance documents exist for industry to consult, they contain no real guidance for their technical assessment. This poor understanding of the behaviour of these highly flexible structures, coupled with changing industrial practices involved with their construction, means that there continues to be accidents from stability collapses and tie failures during the temporary state. The aim of the project is to establish the strength and stability of reinforcement cages in their temporary state to make suitable recommendations and assessment methodologies to improve industry guidance and best practice leading to a safer construction environment. This research is being carried out by Konstantinos Kalfas under the supervision of Dr Brett McKinley. If you are interested in contributing to either of these projects please contact the Director of the Centre of Excellence Dr Andrew McNamara. Facilities Civil Engineering Laboratory We have access to an array of recently refurbished facilities, including exceptional laboratories. The Geotechnical Centrifuge Facility is the centrepiece of the Civil Engineering Laboratory which also accommodates a large flexible laboratory space used for centrifuge model preparation, model testing at 1g, concrete testing and teaching.

Mabey debuts real time load monitoring

A new wireless load monitoring system is in use at an Oxford construction site to provide real-time measurement of forces on basement props. Temporary works specialist Mabey is using its new LIVEpin load monitoring system for the first time to monitor prop loads at the 85m x 300m basement propping scheme for the £500m Westgate Centre redevelopment. Laing O’Rouke is the project’s main contractor for Crown Estates and Land Securities. Sitting in the place of the shear pin that anchors a prop, Mabey’s LIVEpin technology comprises a data-enabled shear pin that measures the axial load on the prop, communicating wirelessly with on-site dataloggers that save and retransmit the data. Readings are transmitted every 30 minutes. Although LIVEpin was not specified for this project, Mabey opted to install LIVEpins on two out of the 114 props it has supporting the excavation. The system allows for the setting of load thresholds which, when exceeded, trigger a switch to a 60-second reporting cycle to enable fine-grained analysis and recording. Once loads drop below the preset threshold, the reporting cycle is reset to every 30 minutes. The dataloggers on site store the data and simultaneously upload it to the Mabey LIVEsite web portal for real-time monitoring and analysis. Mabey engineering director Dave Holland explained: “We wanted to be able to ascertain the load in a strut using the most accurate method possible. By locating the gauges in the shear pin at the end of the strut, we have achieved an exceptionally high accuracy of ±2% under concentric and eccentric loads and at varying temperatures and magnitudes. Redundancy is built into the system, so the LIVEpin and the dataloggers store data as well as transmitting it, meaning that no data is lost in the event of a network or wireless outage.” Mabey’s LIVEpin is the latest addition to its range of LIVE instrumentation products, which includes environmental monitoring, geodetic and geotechnic monitoring, and temperature monitoring, all integrated into Mabey’s LIVEsite web portal.
