Frequently asked

Glossary

1

GWW (Grond-, Weg- en Waterbouw)

The Dutch shorthand for the earthworks, roadbuilding and waterworks sector that InfraRelatiedagen serves. If a Dutch exhibitor describes itself as a GWW contractor or supplier, it works in this civil engineering field rather than in building construction.

2

RAW specifications

The standard Dutch specification system used to describe and price civil engineering works in public tenders. Exhibitors at Hardenberg often present products that are written into RAW bestekken, so buyers ask which RAW clauses a product satisfies.

3

CO2-Prestatieladder (CO2 Performance Ladder)

A Dutch certification that rewards companies for measured carbon reduction and is used as a tender advantage in infrastructure contracts. Suppliers on the show floor frequently display their ladder level as proof of emission performance.

4

Sewer relining

Trenchless rehabilitation of an existing sewer by pulling or inflating a liner inside the old pipe. A recurring product family at the fair, aimed at municipalities replacing ageing riolering without digging up streets.

5

HDD / gestuurde boring (horizontal directional drilling)

Steerable trenchless drilling used to lay cables, ducts and pipelines under roads, railways and waterways. Exhibitors show rigs, drilling fluids and locating equipment for these crossings.

6

Kabels en leidingen

Dutch for cables and pipes, the utility network layer that runs beneath streets. The term covers gas, water, electricity, data and district heating lines, and it appears across exhibitor catalogues at the show.

7

Herinrichting openbare ruimte

The redesign of public space such as streets, squares and verges, including paving, drainage and street furniture. Municipal buyers visit the fair looking for suppliers across this whole package.

8

Circular asphalt

Asphalt produced with a high share of reclaimed material or at lower production temperatures. Roadbuilding exhibitors increasingly present it as a way for provinces and municipalities to hit CO2 targets.

9

Verkeersmaatregelen (traffic management measures)

Temporary signage, barriers and diversion plans required when works close a lane or road. Suppliers of these systems exhibit alongside the contractors who have to implement them.

10

BIM for infrastructure

Building Information Modelling applied to roads, bridges and waterworks, producing a digital model used through design, construction and asset management. Software and survey exhibitors use it as the integration story across the show floor.

11

Area development (gebiedsontwikkeling)

Integrated planning of housing, infrastructure, water and green space in a district or region. It explains why the fair draws municipal and provincial planners alongside pure roadbuilding contractors.

12

Beheer en onderhoud

Asset management and maintenance, the ongoing care of roads, bridges, sewers and waterways. A large share of public buyers at InfraRelatiedagen come for maintenance solutions rather than new-build projects.
