The strength of GRAHAM’s highways and rail sector expertise has been recognised by Countryside Zest (Beaulieu Park) LLP and Highways England following the recent award of a design and build contract for the Chelmsford East Beaulieu S278 Works (RDR Phase 3) project. The works in Chelmsford, Essex, comprise of a new viaduct over the Great Eastern railway and A12 and carriageway works (RDR Phase 3) linking into the Boreham Interchange. The scheme, which is being directed by Countryside Zest in partnership with Highways England, is subject to a single-phase procurement process, although the works will be split into two phases. The first, a £1.4m-valued ‘Stage 1 Pre-Construction Services’ appointment, will focus on design development in order to secure technical approval from the relevant authorities, including Highways England and Network Rail. Detailed site surveys and investigation, plus a robust assessment of possession requirements and timescales, represent complex elements of this phase. Stage 2 ‘Construction’, with an estimated value of £11.8m, will then involve the commencement of an engineering and construction programme based on the agreed outputs from Stage 1. Track record GRAHAM has a proven track record in the Chelmsford area having completed the award winning A138 Chelmer Viaduct – a £32m strategic highway, which has increased transport capacity and significantly improved journeys for motorists, cyclists and pedestrians. GRAHAM’s Managing Director for Civil Engineering, Leo Martin, is looking forward to his team delivering a similar high-calibre piece of infrastructure as part of the Chelmsford East Beaulieu S278 Works project. “This contract award is a tremendous result for us and it once again underlines our combined approach and reputation for excellence in both the highways and rail sectors,” said Leo. “The first phase of this contract requires a fully-coordinated design methodology that meets the approval and standards of Highways England and Network Rail. We have enjoyed long-term relationships with both organisations and fully understand their technical requirements. “I’m confident that our existing knowledge and design expertise will not only meet, but exceed, their expectations, which will ensure a seamless transition to Stage 2 and the beginning of the construction works. “As we proved with the A138 Chelmer Viaduct, we use our expertise and creativity to identify and implement solutions that reduce cost, drive efficiency and enhance outcomes and therefore we are looking forward to replicating this approach for the Chelmsford East Beaulieu S278 Works project.” Phasing The approved phasing of the development requires the initial stopping up of the existing Generals Lane highway and the subsequent demolition of the bridge structure, which currently crosses the Great Eastern railway line in advance of the commencement of the RDR Phase 3 carriageway and bridge construction. The design requirements for the project include a radial distributor road, a bridge structure crossing the Great Eastern mainline and drainage and services. Design work is well under way and is expected to be completed in 2020.
Being able to measure flow accurately is extremely important to many applications – this is especially true in industrial plants, where it can make a genuine difference to a company’s ability to make a profit. Lacking an understanding of flow can lead to issues not being corrected and the will impact an organisation’s bottom line. To measure flow, you need an instrument known as a flow meter. These devices are mused to measure either the volumetric or mass flow rate, or the amount of fluid passing through a pipe. Flow meters are used in a variety of different applications in measuring their volumetric flowrate or their mess flowrate. The actual application defines the type of capacity of the flow meter; both liquids and gases are measured in terms of volumetric and mass flowrate. There are actually many different types of flow meter, and the one that you need depends entirely on the application that you want to use it for. In this article we take a look at five of the common types of flow meter to understand their applications. Differential pressure flow meter One of the more common forms of flow meter found in applications around the world, differential pressure flow meters are often used in the oil and gas industries. They also have applications in everything from HVAC and pharmaceuticals to mining, paper and chemical production – their uses are clearly extremely wide. These meters measure the differential pressure across an orifice where the flow is related directly to the square root of the differential pressure that is being produced. The meters work with two elements: primary and secondary. The primary element produces a change in kinetic energy either through a flow nozzle, an orifice plate or a venturi flow meter. The secondary element is used to measure the differential pressure and then provide the signal. Positive displacement flow meter Positive displacement (PD) flow meters are well known for being extremely accurate. This means that they have a range of uses in the transferring of oil and other fluids such as gasoline and hydraulic fluid. They even have use around the house with applications in water and gas. PD flow meters are used to measure a volume filled with fluid, deliver it and then fill it again. This allows the meter to calculate the amount of fluid that has been transferred. The majority of forms of flow meter measure some sort of parameter and convert the value into a flowrate – PD flow meters actually measures the flow of the fluid. Some of the meters include piston meters, nutating disk metres and rotary vane type meters. Velocity flow meter Another common form of flow meter is the velocity flow meter. These instruments are used to measure the velocity of the stream in order to calculate the volumetric flowrate. Velocity flow meters are less sensitive when the Reynolds number of the fluid is higher than 10,000. Some examples of velocity flow meters include electromagnetic and sonic/ultrasonic, turbine, paddlewheel and vortex shedding flow meters. Mass flow meter Mass flow meters measure the force resulting from mass accelerating through a pipe, this means that they are most effective in mass-related processes. They work by measuring the force of mass moving per a unit of time, rather than volume per a unit of time. Common forms of mass flow meters include thermal dispersion meters and Coriolis mass meters. Many of the major applications for mass flow meters are related to chemical processes. They are often found in the gas and chemical industries, as well as throughout power, pharmaceuticals, waste water and mining. Open channel flow meter Finally, we come to the measurement of liquid in open channels. This occurs in v-notch, weirds and flumes. They allow for a concentrated or a limited free-flow of liquid depending on the shape of the structure. Some of the most common applications for open channel flow meters include measuring free-flowing liquids such as those found in rivers, streams or sewers. Image courtesy of: Applications Engineering
If you’re involved in a farming operation, then you’ll be aware of just how much energy is needed to maintain a living. Whether it’s tractor use, ensuring the needs of livestock are met, or heating any number of crop stores – all are extremely energy-intensive. The predicament can be even more critical during the autumn and winter months, when harsh conditions make it more difficult for farmers to harvest, package and distribute produce. Add this to the challenges that come with heating rural, remote and off-grid agricultural locations (traditionally served by inefficient fuels like oil), and a farm’s energy supply can become quite problematic. For farmers looking for a greener, cheaper and more effective off-grid fuel solution that’s reliable even in colder seasons, LPG (liquefied petroleum gas) could be an alternative. LPG has increasingly become a go-to for farmers looking to meet ongoing heating or operational needs without compromising on outputs and the quality of their end product – or becoming dependent on an expensive alternative fuel. Farming and off-grid use Available in gas cylinder and bulk form, LPG provides an alternative to oil and solid fuels for off-grid agricultural use. It can be used for heating or transport in all types of farming processes, and delivers a range of operational and environmental benefits. From dairy processing and poultry rearing right though to maintaining the perfect temperature for crop drying (or even propane enrichment of biomethane in anaerobic digestion plants), farmers have turned to LPG for its cleaner, more cost-effective and easily-controllable capabilities. For farmers looking to understand the benefits of LPG, here is advice on how gas can become an essential part of efficient farming in the winter months: 1. Livestock and energy usage Whether it be barn ventilation, lights, supplying food and water or manure handling, poultry cultivation requires a huge amount of energy. For birds and livestock, a constant heat supply is crucial to their survival – especially during colder seasons. By choosing LPG, farmers and animals can potentially benefit from: – An efficient and cleaner-burning fuel, LPG reduces the risk of contamination within livestock (through feeds and litter) – ensuring that animals are kept as safe as possible. – The moisture produced by LPG heating is the perfect level to promote speedy feathering and weight gain amongst poultry. – Choosing an LPG supplier with a national supply network means deliveries can be made quickly and efficiently, keeping birds warm all-year round. 2. Weighing up the green benefits For farmers looking for greener ways of working, LPG can offer environmental benefits. It’s a lower-carbon alternative to conventional fossil fuels, cutting carbon emissions by approximately 15 % compared to heating oil (and 33% compared to coal). It also doesn’t produce black carbon – which is a major contributor to climate change. As a transport fuel for tractors or other farming machinery, it’s also estimated that LPG (or propane) produces up to 24% fewer greenhouse gas emissions than gasoline, and 11% fewer emissions than diesel engines. Not only that, but the risk to the local environment is also kept to a minimum, as propane is non-toxic – providing a cleaner, greener, and cost-effective fuel solution for all kinds of farming uses. 3. When heating is needed for horticulture Maintaining constant temperatures for commercially grown plants and flowers is crucial to securing profits. When temperatures begin to drop, plants are naturally at greater risk of being damaged by frost, so it’s important to have the right heating system in place. LPG, as opposed to other off-grid options like oil, allows plant growers to benefit from a cleaner burning fuel, ensuring crops remain free from contamination. Depending on the size of the operation, farmers can also choose between an LPG gas bottle (which can easily be handled and lifted) and LPG gas tanks (which can be topped up automatically), meaning an energy system that delivers a constant heat supply for horticulture. 4. Using LPG to dry crops and grains When it comes to drying crops and grains, an LPG system can be a huge commodity to farmers looking to dry their produce quickly. As a highly controllable source of fuel, LPG makes for a more precise drying process, allowing farmers to maintain ideal levels of moisture without over-drying. The result is quicker drying all round, whilst also enabling farmers to preserve the quality of their crops, and ensure that the final product meets market specification. Additionally, with LPG grain drying technology, there’s the potential to recycle heated air, providing an even more efficient way to dry grain, without increasing fuel consumption.

Major public realm improvements and upgrades around Prescot train station are due to commence, along with walking and cycling routes to the £26 million Shakespeare North theatre. The 350-seat, 30,000 sq ft Jacobean court-style theatre also includes a study centre, education, and exhibition space. Knowsley Council is set to formally sign off £8.2 million funding for this project. Shakespeare North, which is currently being built by contractor Kier, will benefit from better links, which are set to transform the area around the railway station and features a shared-use walking and cycling route from the station to the town centre and on to the theatre. The project also includes a remodelled car park to up the number of spaces from 38 to 48, additional lifts to provide step-free access to the station and platforms and better wayfinding and signage to direct visitors to the town centre and towards Knowsley Safari Park. Liverpool City Region’s Strategic Investment Fund offered £7.9 million and the majority of it will be drawn down between 2019 and 2021. There is also a local contribution of £186,000 to take the total funding package up to nearly £8.2 million. Knowsley Council is set to sign off the funding at a meeting next week. Tarmac and SSE are the chosen contractors for the scheme. They will deliver all the public realm works, while Network Rail will deliver the new lifts and station access. Meanwhile, Kier is set to complete the theatre by December 2020, after beating rival bidders Morgan Sindall and Wates to the job last year. The public realm works are also likely to be completed around the same time. The theatre has been backed by £5 million from the Government, which was first announced by then-chancellor George Osborne in May 2016. The council is also providing £6 million towards the scheme, with the remainder coming from a £14 million contribution from the Liverpool City Region Combined Authority Single Investment Fund.
A number of multi-million pound contracts has been awarded by Network Rail in Scotland and the North East. Totaling £467 million, the contracts were handed over under two Control Period 6 frameworks. Valued at £320 million, the most significant contract for a renewals and enhancements framework went to BAM Nuttall. The contractor will replace and refurbish structures across the rail route, as well deliver improvements at stations. Meanwhile, two Geotech frameworks worth a combined £147 million have been awarded to Story Contracting (London North East) and QTS (Scotland) as part of the procurement process. “We are exceptionally proud of the collaborative work QTS has carried out during the last control period, with some outstanding geotechnical projects delivered across Scotland. It is a testament to the hard work of our team during the CP5 contract, and the strong relationship that we have built with Network Rail, that has allowed us to be successful in this CP6 tender process,” said Alan McLeish, QTS Managing Directo. “Our expertise and commitment to finding further efficiencies for Network Rail by using innovative plant and methods, stands us in excellent stead to continue providing a high standard of work over the next five years,” he added. In addition, five-year contracts have also been awarded, with an option of two-year extensions on the Geotech framework. “Work to renew our infrastructure is increasingly important to improve reliability for our passengers, and making sure we have the right suppliers to deliver those improvements is paramount. We look forward to working closely with our supply chain to build on the progress that has already been made and ultimately, build a better railway for our customers,” commented Kris Kinnear, Interim Regional Director for SNE. The latest contract awards complete the procurement activity for Scotland and North East, which is anticipated to hold one of the largest work-banks for the coming five-year funding period.
A vacant land at South Humber Bank Power Station will see the arrival of a new multi-million pound energy centre. Set to create around 50 new jobs, the £300 million facility would generate 49.9MW of electrical power, which is the equivalent to supporting around 500,000 homes. The planning application for the scheme has been submitted by EP UK Investments Ltd (EPUKI), which owns and operates South Humber Bank Power Station. The application was validated in December by North East Lincolnshire Council and a decision is due to be made by the end of March. “We are very pleased to announce the proposed development of an Energy Centre at the South Humber Bank Power Station and it follows the completion of our recent £53 million investment in the existing site,” said James Crankshaw, head of engineering at EPUKI. “The project is not dependent on securing a Power Purchase Agreement (PPA) or other form of secured income such as a Contract For Difference (CFD) as other EFW projects have required and, as such, EPUKI expect to progress to the construction phase soon after planning is approved,” he added. If the planning permission is granted, the South Humber Bank Energy Centre will be powered by approximately 620,000 tonnes of refuse-derived fuel annually. “The Energy Centre will provide much needed new power generation and energy recovery facilities, as well as creating permanent local jobs. We look forward to working with the planning authority and local community over the coming months,” James concluded. A subsidiary of Europe’s seventh biggest power generator EPH, EPUKI aquired in 2017 2.2GW of combined cycle gas turbine (CCGT) power stations from energy giant Centrica. Moreover, the firm put plans in place last year to boost its portfolio further by commissioning a new 420MW biomass power station at Lynemouth, Northumberland. EPUKI also has development consent to deliver up to 4.2GW of new build CCGTs in Eggborough and King’s Lynn.
A £2 million funding boost has been offered to a number of energy projects in the South West. Bristol City, Devon and Plymouth Councils secured a grant from the European Investment Bank and the European Commission to fund new energy efficiency, renewable, sustainable transport and heat networks projects across the region over the next three years. “This is yet another really exciting step towards carbon reduction in Bristol. The scale of sustainable development generated by the last ELENA grant made an enormously positive impact on our ability to deliver clean energy for the city, so we have high hopes for the opportunities that come with this latest round of European funding,” said Cabinet Member for Energy, Waste and Regulatory Services, Councillor Kye Dudd. “It’s great that Bristol has once again been recognised as a national leader in the field of sustainability as our goal to become a carbon neutral city by 2050 moves a step closer. It’s even more exciting now that we are in a position to share our knowledge and expertise with other parts of the region, helping them to reduce carbon and provide clean energy to towns and cities across the South West,” Cllr Kye added. Bristol City Council is the lead organisation, therefore it will manage the projects with its central delivery team. Councillor Roger Croad, Devon County Council’s Cabinet Member for Environment, also commented: “The funding will help us to kick start a range of projects which will support the council in delivering its target of reducing the Devon region’s carbon emissions by 80% by 2050. These projects will also give us more control over energy use, will reduce air pollution from transport and generate energy which will improve the quality of life for Devon’s residents.” “We anticipate that this funding will stimulate Devon’s renewable energy sector and lead to at least £16 million being invested into low carbon projects in the county,” Cllr Roger concluded.
Building professionals understand that there are many steps to ensuring that the power system in a construction runs properly– but what are the essential power requirements to remember for large projects? These three tips will highlight the key areas to aim for when incorporating secure power sources and appliances into the process of building on a large scale. Speedy energy sources are vital for any building, especially if built to host a range of different activities simultaneously, such as an apartment block or a hospital. Cost-Effective Outlets When planning a large-scale construction, such as an apartment block or school, ensuring that energy can be consumed as cheaply as possible can help maintain the reputation of both businesses in a building partnership. This can be achieved most easily through smart planning by the building and design team, a process that benefits immensely from regular engagement with the buyer. Advice from energy-efficiency as well as financial experts may also help to produce a power source design that is affordable for both the buyer and the prospective property users and works to protect the environment through conserving energy. Locating cost-effective power sources is, therefore, an important requirement, and hugely advantageous, for a large construction project. Green Energy Sources Building regulations are greener and more sustainable than they have ever been: initiatives like the Code for Sustainable Homes ensure that a high percentage of properties built in the UK are as energy-efficient as possible – but unfortunately, this is yet to extend to all buildings. So, when it comes to large structures, it is especially important to use the greenest products on the market. Construction project leaders that locate brands offering AC-DC power supplies for multiple applications, who comply with the latest global energy efficiency standards such as XP Power, are able to power large buildings through efficient energy sources. As this benefits the reputation of a building company as well as the planet, professionals who adopt a greener power supply service may even benefit from more building business partnerships in the future. Back-up Power Supplies Once power has been installed in a large property or construction, a back-up system is necessary for making sure that operations expected to take place in the building can still function should the original supply cut out. This can be particularly critical for large buildings where supplementary power facilities can guarantee that a large number of people are not left without means to carry out essential activities like cooking when one power source fails. Power failures that have occurred in densely-populated areas like East Midlands Airport highlight how full accessibility to all power systems can help to secure the constant and reliable running of energy in a large, heavily-used area. Large Construction Projects require a huge amount of attention and consideration in their planning, particularly when it comes to power sources. However, the environmental and financial advantages that successful power systems bring to most people underlines the significant role that building continues to play in everyday life.
A 12-month contract has been agreed between Siemens Gamesa and the ABP Port in Hull to store 37 wind turbine blades destined for the world’s largest offshore windfarm, the Hornsea One Project. A six-acre area located at the Port of Hull’s Eastern Access, on King George Dock, is now being leased for the storage of the 75 metre, 30 tonne blades in order to accommodate the expanding business. An operation is underway to transport the fibreglass blades nearly two miles from the current site on Alexandra Dock. “We’re proud to be able to say that we have been an essential link in a major green project such as this, which will eventually see the blades powering one-million homes. It’s also another example of our expertise in handling such large and specialist components. We have worked closely with Siemens Gamesa to offer solutions and to support their business growth, so that together as partners, we can keep Britain trading and provide the nation with environmentally-friendly power,” commented David Morriss, ABP Humber Head of Property. The transportation process requires for a remote-controlled loader to be guided by an operator to carefully transport the wind turbine blades through the port to its new location at 5mph. Each blade takes around 1 hour 15 minutes to move during the early hours of the morning to cause minimal disruption to port traffic. “Siemens Gamesa is delighted to again be working with ABP, continuing a ground-breaking partnership in Humberside. To deliver clean, green energy to millions of UK households is a complex team effort, and ABP is a crucial member of that team,” said Anton Bak, Factory Director, Siemens Gamesa Renewable Energy Hull. Hull City Council has also made improvements to the Northern Gateway Roundabout to help facilitate the movement of abnormal loads, as well as create further investment opportunities in the city and port. The council utilised funding from the Green Port Growth Programme to create a route through the centre of the junction and part-time signals to control traffic during the movements.
