Structure, Operation and Administration


The work of the Scientific Committee will take place in the context of Highway’s England’s A303 Stonehenge: Amesbury to Berwick Down Road Scheme. The Committee is not expected to address wider questions of need or strategic choice, but to support implementation of the project in a way that best addresses its opportunities and impacts and ensures it is managed for the benefit of the OUV of the WHS. The Committee will not have any statutory function in its own right, but its advice and guidance will be available to inform the statutory consent processes. Highways England should give careful consideration to any advice given by the Scientific Committee and have due regard to that advice, general recommendations and the particular observations of the Committee on specific aspects of the scheme in relation to its archaeological mitigation.


The Scientific Committee will not be required to provide a consensus view but will capture the full range of expertise and advice of the Committee’s membership. The Committee will have an independent chair.


Both HMAG and the Scientific Committee will be supported by a secretariat provided by Highways England. The secretariat will prepare agenda and record minutes / actions, collating the range of views and advice from both HMAG and the Scientific Committee and managing the provision and distribution of project information to Committee members. The secretariat will prepare a formal report to Highways England on meeting proceedings.


The Scientific Committee will meet quarterly or at such frequency as the needs of the project dictates. From time to time and as the needs of the project dictates the advice of individual members of the Scientific Committee may be sought outside of Scientific Committee meetings in relation to their particular areas of expertise.


Conduct Guidance to individual Scientific Committee members


Conduct should be in the spirit of the Nolan Principles1 for public service. All Scientific Committee members are requested to respect the confidentiality of proceedings. The Chatham House Rule2 will apply to the Committee meetings. Highways England may from time to time lead news releases about the workings of the Scientific Committee. Consultation prior to release will always be sought from Committee members. Consequently, individual members or their organisations may adopt a Highways England news release and disseminate information after Committee meetings – recognising nothing should be done to identify, either explicitly or implicitly, who said what.


Reimbursement of Travel Costs


Although Scientific Committee members will not be remunerated for participation in the Committee Highways England will reimburse reasonable (evidenced) travel expenses.
