Appendix A – Assumptions register

Appendix A – Assumpt ions register

Note – these assumptions are used for the purpose of drive option identification onlyand may change as design develops.

Item Criteria/const raints Requirements and assumptions

1 Main tunnel design general

Main tunnel internal diameter from ZoneS11 Abbey Mills to Zone S3 WansdworthBridge

7.2m internal diameter

Main tunnel internal diameter from ZoneS3 Wandsworth Bridge to Zone S0 Acton

6.5m internal diameter

Main tunnel internal diameter from ZoneS2 Barn Elms to Zone S0 Acton

6m internal diameter

Main tunnel primary lining Reinforced concrete segment lining thickness0.35m

Main tunnel secondary lining (assumed itis required for this EOR) In situ reinforced concrete lining thickness0.3m

Vertical alignment Alignment to give adequate clearance tothird-party infrastructure (including theproposed National Grid Kensall Green cabletunnel) with tie in to Abbey Mills Shaft F.

Not less than 2m clearance below existing BTOpenreach tunnel

G di t l ibl t 0 12%



Appendix A – Assumptions register

Item Criteria/const raints Requirements and assumptions

CSO drop shaft size 6m to 24m internal diameter

Shaft construction and type Shaft type to suite size, depth, ground andgroundwater conditions.

4 Programme const raints

Overall duration of construction period 6 years

Main tunnelling long average drive rates Programme to allow for initial start-up periodfollowed by long average tunnel drive rateswhich are 100m/wk in London Clay, 90m/wk inLambeth/Thanet Sand, and 80m/wk in Chalk.EPBM in Chalk 50m/week.

Main long average secondary lining Programme to allow for initial set-up followedby rate of 140m/wk.
