It is therefore proposed that, at the tender preparation stage, issues pertaining to the environment be handled as follows:
. The Economic Feasibility and Preliminary Engineering Design Report should take into account the recommendations of the Environmental Impact Assessment Study carried out;
* At the Detailed Design Stage any necessary environmental mitigation (or enhancement) measures identified in the feasibility stage should be incorporated into the design and all its construction details drawn up;
* Pre-qualification of contractors for invitation to tender should be made to require, as far as is possible, submission of an environmental protection statement and a health and safety
statement, which would then be developed into full action plans in the final bid.
In order to assist with this, existing provisions in the Conditions of Contract which refer to environmental issues are listed in the tables below.

Construction details for environmental mitigation measures identified at feasibility stage are normally drawn up by the Consultant in the Book of Drawings which forms Vol. IV of the Contract Document.
The Special Provisions to the General Specifications normally contain a write up on management of environmental matters
The Bill of Quantities would normally contain pay items based on the General Specifications' measurement and payment, for mitigation measures against the impacts on the environment that are to be executed.
142
The Items in the Bill of Quantities relating to environmental mitigation measures should include the following aspects of work:
