Expansion of Gasunie OLS

On behalf of N.V. Nederlandse Gasunie, De Romein Group executed the Deventer OLS project. This project was divided into three sub-projects: relocating the testing area & reorganizing the warehouse, optimizing the housing conditions, and expanding the assembly hall.

For this project, we carried out the following tasks:

Parking Lot

• removal of the existing paving
• supply and installation of drainage and catch basins
• grading to the construction height
• finishing the sand bed
• supply and installation of approximately 4000 m2 of concrete pavers
• supply and installation of approximately 750 meters of concrete curb
• supply and installation of street lighting

Assembly Hall Construction

• supply and installation of steel pipe piles
• installation of the foundation beam
• supply and placement of 63 tons of steel structure
• supply and installation of approximately 1500 m2 of cladding
• supply and installation of approximately 600 m2 of roofing
• supply and placement of 172 concrete slabs
• supply and placement of a 20-ton overhead crane

Internal Renovation of Canteen and Offices

• demolition and removal work
• supply and installation of floor tiles
• supply and installation of carpet tiles
• supply and installation of sliding partitions
• supply and installation of the kitchen unit

Internal Renovation of Warehouse and Welding Area

• demolition and removal work
• installation of approximately 150 m2 of concrete floor
• supply and placement of approximately 150 m2 of aerated concrete walls
• supply and placement of approximately 110 m2 of hollow core slab flooring
• application of coating on concrete floors
• supply and placement of steel staircase and railing
• supply and placement of warehouse lift
• supply and placement of overhead door

Internal Renovation of Testing and Workshop Area

• demolition and removal work
• supply and installation of steel pipe piles
• installation of foundation beams
• installation of approximately 250 m2 of concrete floor
• supply and placement of approximately 275 m2 of cellular concrete block walls
• application of coating on concrete floors
• supply and installation of frames
• supply and placement of steel staircase and railing
• supply and placement of overhead door
• supply and placement of a 5-ton overhead crane

The Challenge

In the warehouse and testing area, we worked with multiple concrete floors treated with a specific type of liquid-tight coating. This makes the floor highly durable and slip-resistant.

Height Difference

The height difference on the site posed a challenge. We addressed this by installing a retaining wall. Afterward, the construction of the assembly hall could begin.

Parking Lot

A portion of the parking lot needed to remain accessible for Gasunie employees during the work process. Therefore, we staged these activities in phases.
