The development of smart modular construction processes, combining steel, concrete and wood with factory-prefabricated modules, demonstrates the focus that Eiffage Construction places on innovative building methods. The aim is to consolidate efficiency, quality, safety and durability.
Building is Eiffage Construction’s core business. The company continuously seeks to innovate to improve the quality, durability and safety of its designs, as well as the efficiency of its construction methods. Whether through progress in timber construction processes (smart modular construction) or through the mass production of ready-to-use HVA ConceptTM bathrooms, Eiffage Construction continuously strives to reduce its environmental impact, its production times and costs, and thereby improve its competitive excellence.
Unlike traditional “wet” building techniques, modular (dry) construction does not require water and makes use of eco-materials such as wood that are environmentally friendly.
Timber, the core of the smart modular process, offers a number of advantages:
Used alone or combined with concrete, glass or steel, timber can be adapted to all types of construction project: new builds or renovations, residential or tertiary applications, facade structures and high-rises.
This is why Eiffage Construction has been developing timber-based construction projects for over a decade and has even created a subsidiary specialising in projects in which wood is dominant.
Eiffage Construction’s main accomplishments in wood include:
As part of its ongoing drive to reduce build times and costs, Eiffage Construction has developed a range of factory-built products ready to be installed in buildings undergoing construction.
Mass customisation: the bathroom modules in the HVA ConceptTM range made at Eiffage Construction Industries’ factory in Fresnay-sur-Sarthe are available in four different versions and finishes (PVC, ceramic, tiles and paint/tiles).
These bathroom units, featuring a concrete floor structure, are entirely factory-assembled and include all facilities such as toilets and showers as well as all necessary connections for electricity, plumbing and ventilation. HVA ConceptTM bathrooms can represent time savings of 5 to 7 weeks for buildings with 80 rooms, such as retirement homes, hotels or serviced residences.
HVA ConceptTM bathrooms satisfy the most stringent standards in terms of acoustic performance and fire resistance. They present the added advantage of being low maintenance and recyclable.
Whether the aim is to monitor the durability of structures throughout their life cycle or to reduce repetitive tasks on site, Eiffage Construction is engaged in a permanent drive to test new technologies.
Eiffage Construction is pioneering new ways of monitoring concrete structures through a scientific partnership and cutting-edge experimental platform.
Eiffage Construction Nord, the French Research Institute for Software and Hardware Components for Information and Advanced Communication (IRCICA), the Civil and Geo-Environmental Engineering Lab at Lille University (LGCGE), and the Innovation Centre for Contactless Technologies (EuraRFID - CITC EuraTechnologies) have together created a smart totem in Villeneuve d’Ascq to validate findings on smart concrete. The totem is equipped with a network of autonomous, wireless sensors that measure creep, temperature and humidity levels in reinforced concrete in real time and during an entire life cycle.
The exoskeleton (or exosuit) is a mechanical system that mirrors the human skeletal structure. It makes lifted objects feel much lighter and relieves intense and repetitive effort. Used within the construction industry, exoskeletons could help reduce risks linked to carrying tools and make it easier to handle heavy objects.
Pradeau Morin, a subsidiary of the Eiffage Group specialising in the rehabilitation of historical monuments, has performed trials with the exoskeleton on the renovation of a mansion in Paris. Findings show that this technology is best suited to repetitive tasks in open spaces. For the time being, its bulk prevents use in confined spaces. However, it has demonstrated a tangible ability to reduce fatigue and repetitive strain injury.
