7/28/2019 Guide to Ground Settlement- April 2014

1/2

The proposed ThamesTideway Tunnel isa major new sewer

urgently required tohelp tackle dischargesof untreated sewageto the tidal RiverThames.

This leafet explains what you need toknow about settlement and how wewould manage any possible impacts

on property.

What is settlement?

For this project, settlement

is a term used to describe

how the ground can move

due to the construction of

new infrastructure below the

surface. The constructionof shafts, tunnels and

combined sewer overow

(CSO) interception works

will cause some small

movements in the ground.

Depending on the location

and proximity of existing

infrastructure and buildings

to the proposed Thames

Tideway Tunnel we would

expect some ground

movements to aect these.

The extent to which these

ground movements have an

impact on structures would

depend on several factors

including the:

size and depth of the

construction works

existing soil conditions

methods of construction

type of structure, its

condition, and its

foundations.

How could settlementafect me?

In most cases you would not

be able to see the eects

of settlement but in some

cases there may be small

cracks in plaster, and doorsor windows may stick.

How do I qualify fora Settlement Deed?

If you are concerned bythe proximity of a property

that you own to the tunnel

alignment, then you may

be entitled to a SettlementDeed. You can contact us

to nd out more about this

and whether your propertyqualies. You must have a

legal property interest in all

or part of a building which

could be aected.

We must have reasonable

notice from the owner prior

to construction of the partof the tunnel intended to

go under the property. The

notice must give sucientinformation in order for us

to complete the deed. At

this stage we would conrm

or refuse the ownersapplication for a deed. On

receipt of a deed the owner

must return his counterpartcompleted within 21 days.

Where a qualifying building

is in multiple ownership

each owner will be entitledto a deed.

What happens ifI want to sell myproperty?

The deed will remain inplace and stays with the

property.

How would youknow if my propertyis afected bysettlement?

Before construction starts

in the area, an inspectionof the property would be

undertaken to determine

what, if any, monitoring

and surveying would benecessary to accord with

the terms of the deed. The

results of this assessmentwould be made available

to the owner prior tocommencement of relevantconstruction activity.

What if my propertyshows signs ofmovement?

If you become aware ofdamage to the propertythat you believe may be

caused by the projectsconstruction, contact us torequest a further inspection.This would be conductedat our expense and may betriggered by the owner atany time.

We may need to installadditional monitoringequipment or additionalpreventative works tomitigate the eects ofsettlement that may betaking place.

On completion of theconstruction activity inthe area, if there has beendamage caused by theThames Tideway Tunnelor the owner suspects anydamage to the building,we would undertake a postconstruction conditionsurvey. We would write areport which would identifyand explain any dierencesfrom the pre constructioncondition survey that willhave been held on recordby both ourselves and theproperty owner.

Will you pay forany repairs to mybuilding?

Where buildings may beaected by settlement we

will take reasonable steps

to limit the impacts andwill discuss these with the

relevant property owners

and occupiers. If damage

does occur due to ourconstruction works, we

will agree the costs of the

repairs with you before anywork is undertaken.

Do I need aSettlement Deed tobe protected?

No, the deed will simply putinto a personal contract

the obligations andcommitments made in theSettlement Information

Paper which is available on

our website.

Will you bemonitoring alongthe route and atconstruction sites?

We will have detailed

monitoring in placeto ensure the safe

construction of the ThamesTideway Tunnel project

throughout and beyond

the construction period. Ifyou are concerned about

settlement, please contact

us for further information.

What is a SettlementDeed?

If you own a property,you can ask us about a

Settlement Deed which is a

legal undertaking between

ourselves and you as theowner.

We provide this deed to

give reassurance to thosewho during the lifetime of

the project may benet

from us giving a guarantee

on their property.
