The contractor's objectives of how the environment will be safeguarded in the project and on the construction site

Groups: 
  • Design-Build Contracts
Category: 
  • Emissions from the Construction Site
  • Rigging and Operations

Basic

Requirements and Criteria Type: 
  • Award Criteria

Main Objective: 

Motive

Construction site activities can result in relatively large environmental impacts over a short period of time. These could be emissions of greenhouse gases, the production of waste, the use of chemicals, impacts on the local ecosystem, dust, noise, resource use and other emissions to air, ground and water. Some emissions may have greater consequences in cities than in more rural areas.

Argument

If the project has an ambition to reduce the environmental impact of the construction period, it may make sense for contractors to compete on this. This lets you allow contractors to come up with good solutions. This can lead to contractors developing in this area and finding new products, solutions or methods.

Requirement Specification: 

The contractor's objectives and description of how the environment will be safeguarded on the construction site will be evaluated based on the description of the following issues:

  1. How environmental considerations will be safeguarded in the event of time pressure during the construction project. There is a great deal of time pressure in construction projects and it is easy to neglect to address environmental considerations
  2. Emissions of greenhouse gases from the construction site, and reducing these
  3. Construction waste means wasted resources – how will reuse and material recovery be handled?

                                                       

The tenderer is asked to complete table 2.41.1 on environmental qualities on the construction site

Documentation of the Requirement Specification: 

Contractors must fill in table 2.41.1 as documentation of how the relevant environmental issues will be addressed on the construction site.

Issue

Contractor’s goals for the project

XX – must be quantified by the contractor
Brief description of how the contractor will achieve the goals

Score 0-10 (must be filled in by the buyer)

 

a) There is considerable time pressure in construction projects and it is easy for environmental considerations that exceed the minimum requirements of Acts, Regulations or requirements specifications to be neglected [clarify the environmental considerations that are most relevant for the construction project] Qualitative description    
b) Greenhouse gas emissions from construction sites represent a substantial proportion of the total emissions associated with, for example, a city or municipality.  Estimated consumption of fossil fuels by construction machines on the construction site and heating/drying: XX litres    
c) Construction waste is resources that have gone astray

Total amount of construction waste generated by the project must not exceed XX kg/m2 GIA

 

Separation rate: XX% separated
   

Documentation of goal attainment must be submitted before takeover and must contain the following:

  1. Documentation of how responsibility for the environment was addressed in the form of signed job instructions covering the entire project period, conducted risk assessments, the training that has been provided in the project in the form of a signed project participant list, a schedule showing how the environment was safeguarded, and reported environmental deviations.
  2. Statement of the amount of fossil fuel used for various purposes, documented by receipts from fuel suppliers.
  3. Completed waste plan which shows the planned quantity and actual quantity of construction waste by the various fractions, as well as confirmation from the operator of the waste reception centre.
Information about the Requirement Specification: 

If this award criterion is used with the aim of assessing the reduction in emissions from a construction site in relation to a contract, it is important that the client has examined, planned, and facilitated the optimisation of the infrastructure in advance, e.g. district heating or another planned energy carrier. Where there is a need to talk to the market in advance, such that they are prepared and can plan to secure access to available technology such as electricity, hydrogen, etc., the results of the dialogue must be taken account of in the tender documentation such that the tenderer is familiar with these conditions. Read more about what zero emissions construction sites are on Difi's issue pages.

Guidance on documenting waste must be provided in the contract follow-up, what are the practices out there? Do they report once a week? A month? Upon reaching milestones? What is good guidance here? For example, as a waste statement and this should be reported. To what extent is it possible to connect district heating, mobile transformers, etc. If you do not know the practice in your market, you must talk to the market

Contractors will be evaluated based on the contractor's goals for the different issues in the project and the responses in table 2.41.1.

Table 2.41.2: Environmental qualities on the construction site – help with evaluating contractors
Issue

Evaluation of contractor’s responses with examples of what should be provided in the responses from the contractor.

a) There is a great deal of time pressure in construction periods and it is easy to neglect to address environmental considerations properly.

The organisation and management of the environmental work and risk assessments, with suggestions for risk reducing measures such as training, safety rounds, how the environment is included in schedules, etc.

The evaluation will be qualitative. The best scores 10 points on a scale of 0-10.
b) Greenhouse gas emissions from construction sites represent a substantial proportion of the total emissions associated with, for example, a city or municipality. How much energy is estimated for:

Volume in litres of fossil fuels and fuel estimated consumed in the project.

The evaluation is linear where the zero-consumption scores 10 points and the highest consumption scores 0 points
c) Construction waste is recoverable resources, plan for reusing materials in temporary structures during the construction phase

Total amount of waste (kg/m2)

Reuse of materials for temporary structures during the construction phase (formwork, scaffolding, stairs etc)

Goals and measures for separation in excess of the minimum requirement of 60% in TEK17

Possible points for construction waste are 10 points divided by quantity and separation. Points for quantity and separation are added together:

  • The evaluation of quantity is linear where the one with the least waste scores 5 points and the one with the most waste consumption scores 0 points.
  • Evaluation of separation: Whoever separates 100% of their waste score 5 points, those that separate 70% score 0 points, linear method
