ERSIGROUP: Spanish engineering for major infrastructure projects in the UK

Industrialisation is changing the way major infrastructure projects are built around the world. As opposed to traditional methods, an increasing number of projects are opting to shift a large proportion of the work from the construction site to industrial settings, where components can be manufactured with greater precision, safety and efficiency. In the United Kingdom, one of the companies driving this transformation is ERSIGROUP, a company with Spanish roots

From its Loughborough site, the company has become a strategic partner for some of the country’s most significant current infrastructure projects, providing pre-assembly solutions and a high level of expertise in steel engineering for concrete structures

Engineering for the manufacture of one-off parts

Beyond its industrial capacity, ERSIGROUP’s key competitive advantage lies in its detailed engineering. The company analyses complex reinforced concrete projects and optimises the design and detailing of corrugated steel reinforcement to ensure that each element can be manufactured in a viable and efficient manner. To this end, the ERSIGROUP team translates the knowledge gained over six decades of work into practical solutions, creating innovative construction procedures and refining existing ones to ensure precise, efficient and safe results in the use of corrugated steel and its integration into reinforced concrete structures.

The result is the manufacture of large-scale components with tolerances of just five millimetres, a technical requirement that is particularly important when it comes to components intended for major infrastructure projects

Among these components, the large steel frames stand out, some of which weigh more than ten tonnes. The manufacture of these structures requires a combination of detailed engineering, industrial capability and rigorous quality control to ensure that each component complies exactly with the design specifications

Construction moves to the factory

The concept is simple, although its implementation requires a high level of technical expertise. Rather than carrying out all the work directly on site, a large proportion of the components are prefabricated in the factory before being transported to the site and installed

This model offers clear advantages. On the one hand, it enables a significant reduction in construction times. On the other hand, it reduces the need for on-site labour and optimises the use of materials, thereby helping to cut costs and improve the sustainability of projects. In addition to the above, manufacturing in a controlled industrial environment makes it possible, above all, to achieve standards of quality and safety that are difficult to replicate on a conventional building site, particularly in large, technically complex reinforced concrete projects.

The Loughborough plant has a pre-assembly capacity of 3,000 tonnes per month and a capacity of 5,000 tonnes per month for cut and bent bars

Large size and millimetre-level precision

One of the products that best reflects the company’s level of specialisation is tunnel segments. These are precision-engineered steel cages that are embedded within the concrete structure; they are several metres wide and weigh up to eight tonnes, and are essential components in the construction of underground infrastructure, the manufacture of which requires extremely high levels of precision

The ability to produce these components with tolerances of just five millimetres is the result of extensive preliminary engineering work, which involves analysing designs, optimising formwork and developing moulds and assembly processes tailored to each project

With components of this type, a few millimetres can make the difference between efficient installation and problems arising during the construction work

Industrial capacity in the heart of England

The Loughborough plant is one of ERSIGROUP’s key assets in the United Kingdom. Its facilities have the capacity to produce up to 3,000 tonnes per month of pre-assembled components and a further 5,000 tonnes per month of cut and bent steel – a scale of production that enables the company to meet the demands of large-scale projects and maintain high delivery rates

This production capacity, combined with the company’s technical expertise, has enabled ERSIGROUP to consolidate its presence in some of the UK’s most ambitious infrastructure programmes

Today, the company is involved in major UK infrastructure projects, including the HS2 high-speed rail project and the future Sizewell nuclear power station. ERSIGROUP’s involvement in such projects highlights the confidence that major international construction firms and developers place in industrialised solutions capable of delivering efficiency, precision and safety. At the same time, it demonstrates the ability of Spanish engineering and industry to compete in particularly demanding markets and to export knowledge, technology and processes with high added value

El sistema de ERSIGROUP permite reducir el tiempo de trabajo en obra, ahorrar materiales y por tanto emisiones de CO2, disminuyendo los costes de mano de obra y mejorando los estándares de seguridad y calidad

A forward-looking model

The sector is moving towards fully industrialised construction, in which off-site manufacturing, resource optimisation and precision engineering will play a vital role. ERSIGROUP embodies precisely this new approach to infrastructure construction: a combination of industrial capacity and technical innovation that enables the delivery of more complex mega-projects, reduces lead times and costs, and raises safety and quality standards

From the heart of England, the company demonstrates that Spanish industry can play a leading role in some of Europe’s most significant projects and contribute, through detailed engineering and advanced manufacturing, to building the infrastructure of the future
