"Creating this new event with SEIMAT offers the exciting prospect of being able to meet up again with our market in 2021 in an atmosphere which will once again be conducive to dialogue and business. We strongly believe that this gathering will epitomise the resurgence of major construction projects and fresh impetus among all the organisations who work on them and have remained active and innovative throughout the crisis. The display format that we have selected will offer centre stage to demonstrations so that visitors can discover, in real-life conditions, the new solutions and innovative machinery that will help them further increase their efficiency on their construction sites tomorrow. We therefore look forward to meeting up in September for this unprecedented experience at the heart of a life-sized showcase for the future of construction.”

We are delighted and proud to be working alongside Comexposium for the launch of this new trade event in our construction equipment sector. There is a clear appetite for a physical gathering, as expressed by SEIMAT’s member companies, and therefore we quickly identified the necessity of an event in 2021 to support the recovery and dynamism of our market. We want Construction Days to fulfil the expectations of all the stakeholders in our sector; indeed, we co-created this event on the basis of an initial dialogue with manufacturers. We want this event to be a convivial and innovative occasion, focussed on the French market, and a place where exhibitors will be able to promote their service and equipment ranges and demonstrate their know-how.”
