After two years of re-construction and renovation, the Maas Tunnel reopened on 19th August 2019.
The monumental tunnel was built in 1942 and is the oldest in the Netherlands. The recent overhaul and upgrade involved both structural and technical aspects, among them a major alteration of the tunnel ventilation.
The importance and complexity of the job to preserve the monument was further stressed by new regulations. This entailed implementation of a longitudinal ventilation system to create safe conditions for the evacuation of people in the event of fires and to provide fire brigades with smoke-free attack routes. NOVENCO Building & Industry supplied and installed tunnel fans firstly as a temporary measure during the construction phase and subsequently also for permanent use. The installation consists of unidirectional tunnel fans type AUR 1250 and reversible fans type ARC 710, all made of stainless steel. The close cooperation with the municipality of Rotterdam and the Building-combination went smoothly. As stated by the Dutch newspaper AD last week: ‘The Maas tunnel passed its final exams: in case of fire, there will be a storm’ and in this case the storm is guaranteed by NOVENCO’s tunnel fans.
