- John van Roon
from UBA Bouw
In the Karspeldreef in Amsterdam, contractor John van Roon supervised the work carried out by UBA Bouw on the ‘KARSP!’ project.
This involved a transformation project in Amstel III, an area that is predominantly used for offices. But it will become an urban neighbourhood in the future. The Karsp! project is scheduled to build 274 houses, a modest commercial-social programme (about 1,140 m² GFA), a parking garage with 101 parking spots, and a bicycle storage space with 808 bike parking spots.
Construction on a postage stamp
A solution was needed for proper building site facilities to ensure the construction process went smoothly. A collaboration with Heras was sought to find a good solution for enclosing the terrain with access control.
The situation that had to be allowed for:
- Construction on a postage stamp
- Supply route is a busy street
- Lorries had to get off the street quickly
- Lorries have a limited turning circle
- An office landscape with lots of pedestrians around the building site
- Access control required for people and vehicles
- PPE-free area required
- The fences were installed semi-permanently to ensure that they were installed as tightly together as possible. This allowed the fences to be hung on poles with clamps. This removed the risk of stumbling over blocks and no valuable space was needed to install struts.
- A combination of cityfences / readyhoard was chosen as an alternative to traditional mobile fences. These are fences were the lower half is fitted with a sheet piling profile. This minimised the nuisance to pedestrians and speeding traffic from windblown dust as much as possible and partially reduced the visibility of the building site. The employees are also not inconvenienced by headlamps from traffic driving towards the building site. A neat appearance is also an additional advantage of this solution.
- Mobile boom barriers were fitted with ‘skirts’ to ensure that supply lorries could quickly and effectively enter the building site.
- Access control is arranged with Heras Smart Access. So, everyone that is authorised can quickly and securely enter the terrain. And, the overview is in real-time. That is, who works for who and who is located on the terrain in the event of an emergency.
- Finally, the combination of city fences created a safe walkway around the office landscape and provided a clear PPE-free area.
We asked contractor van Roon about his experience with Heras Mobile Fencing & Security on this project
With such a project where we have our required changes, there are always small issues that come up. Heras always find a solution. Everything went as we wanted it to as well successfully installing access control.
Right from the start, Heras provided expert advice and all starting points in the plan were all achieved in practice.
It’s teamwork between us and Heras. We made clear agreements, which led to our preparations and your work always being well coordinated with each other. This resulted in a pleasant collaboration and most importantly, smoothly working access control.
The speed at which you can organise matters is really great.
