Construction Sites

The construction of the Proposed Scheme will be subdivided into sections, each of which will be managed from construction compounds. The compounds will act as the main interface between the construction worksites and the public highway, as well as performing other functions. Construction compounds will either be main compounds or satellite compounds, which are generally smaller. Some compounds will be used for civil engineering works and others for railway installation works, and in some cases for both.

In the Stoke Mandeville and Aylesbury area there will be one main compound and four civil engineering satellite compounds and five railway installation satellite compounds (of which three will continue to use compounds previously established for the civil engineering works).

Risborough Road satellite compound

This compound will be used for civil engineering works only, between south of Stoke Mandeville to Aylesbury. The compound will:

  •  be operational for approximately three years, commencing in 2017;
  •  support approximately 70 workers each day throughout much of the civil engineering works period; but will increase to approximately up to 155 workers each day during the peak period of activity;
  •  not provide worker accommodation facilities;
  •  be accessed via A4010 Risborough Road, A4010 Aylesbury Road to Princes Risborough and then either A4010 to High Wycombe and M40 and/or A4129, A418 to the M40 and/or A4010 Risborough Road, B4009 and A413 to the M40 via A355 and A40 or A40 to Denham and the M40; and
  • be managed from the Small Dean viaduct main compound.

The compound will be used to manage construction of Stoke Mandeville south embankment and Aylesbury south cutting, which will take approximately three years and will include the A4010 Stoke Mandeville Bypass and overbridge, which will take one year and nine months.

There will be one residential demolition, one commercial demolition and the loss of out buildings at one further residential property and one farm holding. Two pylons will also be demolished, together with the cemetery associated with the former site of the Church of St Mary’s.

Princes Risborough to Aylesbury rail overbridge satellite compound

This compound will be used for civil engineering and railway installation works, to the west of Stoke Mandeville and adjacent to the Princes Risborough to Aylesbury Line. The compound will:

  •  be operational for approximately two years and nine months, commencing in 2017, including rail installation works for approximately six months (the civil engineering and railway installation works will run concurrently at this satellite compound).
  •  support approximately 60 workers each day throughout much of the civil engineering works period; but will increase to approximately 130 workers each day during the peak period of activity; and support approximately 40 workers throughout the railway installation works, increasing to a maximum of 50 workers each day during the peak period of activity;
  •  not provide worker accommodation facilities.
  • be accessed via M1 in the east at Milton Keynes, then onto the A421, the A4146 and A418 Oxford Road and/or M40, A41 from Bicester and A418 and/or M40, A418 Oxford Road. The final approach will then be along the site access road to the compound; and
  •  be managed from the A41 Bicester Road embankment main compound for the civil engineering works and from the Chilterns main compound (rail systems) (CFA9) for the railway installation works.

The compound will be used to manage construction of the Princes Risborough to Aylesbury rail overbridge (including rail realignment works), which will take approximately two years and nine months to construct.

Princes Risborough to Aylesbury rail overbridge satellite compound (west)/ Princes Risborough to Aylesbury rail overbridge satellite compound (east)

These two compounds will be used for railway systems installation works only, to the west of Stoke Mandeville and adjacent to the Princes Risborough to Aylesbury Line. Each compound will:

  • be operational for approximately nine months, commencing in 2018;
  • support approximately 20 workers throughout the railway installation works but will increase to a maximum of 25 workers each day during the peak period of activity; and will be managed from Chilterns main compound (rail systems) (CFA9).
  • The Princes Risborough to Aylesbury rail overbridge satellite compound (east) will be accessed via the railway line or via the Princes Risborough to Aylesbury rail overbridge satellite compound. The Princes Risborough to Aylesbury rail overbridge satellite compound (west) will be accessed via the existing Princes Risborough to Aylesbury Line only.
