In Heumen, the Netherlands, Boskalis is working as a subcontractor in a project to build a sluice and channel. The one-and-a-half-kilometer-long work site borders on a residential area.
“We’re actually working in what used to be the local schoolchildren’s playground”, explains Project Manager Marcel ter Wengel. “The main contractor wanted to fence off only part of the site, but with NINA in mind we felt that wouldn’t be enough. Just putting up a ‘No Entry’ sign, definitely won’t keep children off the site. So we said, ‘if you don’t put a fence up, we will’. NINA teaches you to take responsibility for the situation, even if the formal responsibility is someone else’s”. The main contractor has since fenced off the entire site.
