Project Overview

Westminster City Council in partnership with Parliamentary Estates is implementing utility ducting works within the following roads; Parliament Square and Parliament Street.

The proposed works are to include the following:

  • Trench Excavation;
  • Ducting Installation; and
  • Reinstatement of the Public Highway.
The ducting works are programmed to commence on 17 May 2018 and will be undertaken work over a 24 hour period. No noisy work will be undertaken between the hours of 11:00pm and 6:00am. Whilst steps will be taken to try to minimise the impact of noise on businesses, some of the works will be noisy. As a result of the proposed works it is necessary to ban certain traffic movements and close roads to ensure the works can be completed safely and within the planned duration.

Through collaborative working with all key stakeholders which include the list below the aim is to deliver the complete scheme by 22 May 2018:

Parliamentary Estates Directorate (PED);
Westminster City Council (WCC);
Transport for London (TfL);
MET Police; and
London Buses;

The proposed works phasing is designed to achieve the following objectives:
  • Safe working space for construction operatives and all road users;
  • Works areas with the least impact and most effective timescales and safe working space;
  • Access and security to frontages;
  • Minimise impact on surrounding traffic network whilst providing sufficient working space; and
  • Reduce the impact of the works on the traffic network by providing, where possible, at least one running lane.
