Construction, function and follow up of multifunctional constructions for climate adaption

Purpose and goal

The project wants to simplify dimensioning, building and maintaining multifunctional BGG (Blue Green Grey) constructions for road traffic, reduce the risk of flooding and favor trees and greenery. To enable climate-resilient cities (less sensitive to climate-related events) and increase confidence in these constructions. A main aim is that the new solutions are durable and do not require a lot of maintenance. It is therefore important that construction methods are verified. In addition, it is important that already built constructions are followed up in order to build experience.

Expected effects and result

The effect of implementing more BGG constructions is that the load on stormwater pipes during intense rain is reduced. The peak flow can be delayed by using the street´s unbound rock material as a temporary delay reservoir. Trees and vegetation provide biodiversity but also a more pleasant climate. In addition, greenery and trees provide a more beautiful urban environment. The results are to be used, among other things, to simplify procurement by developing regulations for facility construction.

Planned approach and implementation

In order to implement these constructions widely and utilize their ability to handle both traffic loads, stormwater and trees, it is necessary that their long-term function be documented and that the information is widely disseminated. Therefore, we intend to: 1) Build and follow up new test surfaces and instrument these so that deformations, moisture and the living conditions of the trees can be followed up. 2) Evaluate existing multifunctional structures. 3) Produce information and education materials and hold a dialogue with municipalities and actors to share experiences.
