Restoration of the construction site

Basic

Requirements and Criteria Type: 
  • Technical Specification (Requirement Specifications)

Main Objective: 

Compound areas for the temporary storage of equipment, materials, vehicles, extraction of materials, etc. In construction projects, areas of land are appropriated and can result in stresses which alter the original natural environment.

To ensure that the area regains its ecological value and function, the construction site should be restored in a way which safeguards species, habitats and ecosystems.

Requirement Specification: 

Plans must be drawn up which stipulate how construction and compound areas, material extraction and roads will be restored to their original condition prior to withdrawal from the area.

Documentation of the Requirement Specification: 

Report on restoration of the construction site

Plant list

Information about the Requirement Specification: 

According to the UN, loss of the natural environment is as great a threat to the environment as climate. A development project will inevitably involve the appropriation of land and possibly have consequences for the natural environment. However, in order to minimise the impact, it is important to restore any areas that can be restored after the end of the construction period. A search in the Norwegian Environment Agency's nature database map service for valuable habitats in the surrounding area may show which species are indigenous at the site.

The following table lists measures that may be appropriate for returning the site to its original condition:

Measures

Description

Use natural indigenous species for revegetation. None of the species must be registered in the Black List, and the species should be subject to an ecological risk assessment.

Natural indigenous species support locally valuable natural diversity.

For example, some species of butterfly are associated with a particular plant.

Development of multi-layered nature

Plants are often divided into four layers or stories (floor, shrub, understory and canopy). Multi-layered nature contributes to greater natural diversity.

Stream clearance/restorations

Stream clearance or restoration represents a good opportunity to develop rich natural diversity.

Establish ‘rain gardens’ and ditches

Stormwater measures in the form of rain gardens and ditches facilitate the development of indigenous wetland vegetation.

Open sections with sand and small stones

Open sections of sand and smaller stones facilitate sand-dwelling insects, such as bees.

Dead trees or wood

Dead wood, particularly dead hardwood, can provide good habitats for insects.

Establish bug hotels

Bug hotels can create a home for solitary bees, etc.

Set up bird boxes

Support birdlife

Set up bat boxes

Can help to protect endangered species

The construction client must consider what measures should be continued in a contract.

Alien species are species that do not naturally belong in Norway. The Species Database assesses the ecological threat that these alien species pose to Norwegian nature. The species that have been subject to a risk assessment and are registered in the Black List under "high risk" or "very high risk”.

The term natural flora means that the land is restored with vegetation which means that the area becomes a natural part of the landscape/area in which it is situated.

If the measure involves the removal, temporary storage and restoration of agricultural soil, expertise within this field should be brought in and specific requirements established concerning how this should be carried out.

You can stipulate requirements regarding environmental expertise, such as a requirement for an ecologist to be used, as a qualification requirement to ensure that relevant expertise is brought into the project.

Requirement Specification: 

Plans must be drawn up which stipulate how construction and compound areas, material extraction and roads will be restored to their original or natural condition prior to withdrawal from the area.

The supplier must determine the measures that are appropriate for restoring the construction site. The report must document that inspections have been carried out prior to the construction work, including preparatory works, and must at least include:

  • A description of the current situation
  • Measures to increase the ecological value, including a plant list
  • An appropriate management plan for landscapes and habitats in the area for at least the first five years after completion of the project
