Requirements and Criteria Type: 
  • Contract Terms

Main Objective: 

The purpose of conducting an environmental risk assessment for construction work is to prevent accidents and limit the impact on the external environment (and the local environment).

Requirement Specification: 

During the detailed project planning, environmental risk assessments must be conducted in accordance with NS 5814 “Requirements concerning risk assessments”. This must be updated in the event of project changes that result in changed risk conditions.

As a minimum, environmental risk assessments must assess activities that have consequences on the following environmental impacts:

  • Contamination of water and soil
  • Air pollution including dust
  • Natural assets
  • Biodiversity
  • Greenhouse gas emissions from energy and material consumption
  • Waste management
  • Natural resources
  • Discharge to recipients

The contractor must identify the risk of and measures against acute contamination from storage, filling and leakage of fuel and chemicals.

The contractor must document environmental risk using the BIM model, which is followed throughout the project planning and implementation phase.

Prior to the commencement of construction work, environmental risk assessments must be conducted in accordance with NS 5815:2006 “Risk assessment of construction work”. The report must be submitted to the developer no later than <XX> days prior to the commencement of the activity.

Personnel that hold relevant expertise in the coordination of requirements concerning the external environment must conduct the environmental risk assessment through working groups that include representatives from relevant fields, as well as project management and representative(s) of the developer who are authorised to make decisions.

The ALARP principle may be used as the basis for assessing risk-reducing measures. The ALARP principle implies a reverse burden of proof.

This means that identified measures are selected unless there is an unreasonable disparity between costs/disadvantages and benefit. Documentation of the disparity is normally required for major risks.

Documentation of the Requirement Specification: 

Report – environmental risk assessment and overview of prioritised risk-reducing measures.

The contractor must document risk assessment meetings and interdisciplinary reviews to assesses and ensure that the necessary measures are performed.

Expertise must be documented by the requirement and the selected subjects being linked to the project’s environmental goals/ambitions and the other criteria that are selected.

This must be documented through a CV and specification showing the environmental coordinator’s duties and role in the project by the specified deadline. The environmental coordinator must have adequate expertise to manage the coordination of the work to follow up on the environmental goals and requirements for the project.

Information about the Requirement Specification: 

The Norwegian Government Agency for Financial Management recommends that the responsibility for the review of environmental risk assessments with the project team be assigned to qualified personnel with relevant expertise in the coordination of requirements concerning the external environment. The person responsible for the working group must ensure that persons with adequate expertise are present during the review.

Both the conditions and the risk situation may change throughout the different project phases. It could therefore be appropriate to update the environmental risk assessments before and during the implementation phase.

This contractual condition can be used if you are unsure whether the market already has the requested expertise but may be able to obtain the expertise after the tenderer has been selected. If the market is immature in an area/subject, it may be appropriate to allow the contractor to obtain such expertise after the tender competition. If there is adequate expertise available in the market, this can be done in connection with award or qualification.

By default, the ALARP principle forms the basis for assessing risk-reducing measures here. The ALARP principle involves a reverse burden of proof.

This means that identified measures are selected unless there is an unreasonable disparity between costs/disadvantages and benefit. Documentation of the disparity is normally required for major risks.
