The Party Wall Act - Excavation
The excavation near neighbouring buildings falls into two categories:-
In this article we will look at the Three Metre Notice
Three Metre Notice
On a Party Wall award you can have a Three Metre Notice as well as a Six Metre Notice and the normal Party Wall award; so you can have three notices on one project.
Section 6(1)(a) and (b)
This section applies where, and to quote The Party Wall etc Act 1996:
a) a building owner proposes to excavate, or excavate for and erect a building or structure, within a distance of three metres measured horizontally from any part of the building or structure of an adjoining owner; and
b) any part of the proposed excavation, building or structure will within those three metres extend to a lower level than the level of the bottom of the foundations of the building or structure of the adjoining owner.
This section can probably best be explained by the following diagram:
The building owner's property is on the right side of the diagram, in this case if you can imagine it to be a Victorian property, it is likely to have stepped brick foundations, approximately half a metre in depth. The adjoining owner's property is on the left hand side. It is also a Victorian property, again having stepped brick foundations, approximately half a metre in depth. If the building owner wishes to build, for example, on top of a rear single storey, the foundations would then need to be increased to 1 - 1.4 metres or deeper depending on local circumstances. This therefore, assuming of course the adjoining owner's building is within three metres, requires a notice, because it both fulfils the requirement (a) to be within three metres, and (b), stands lower than the level of the bottom of the foundations of the building or structure of the adjoining owner.
Within Three Metres
Remember this Act also applies if it is within three metres.
Frequently Asked Questions - FAQ
Do trial holes or bore holes require a three metre notice when
considering such work, or indeed not?
It is fair to say that over the years we have heard arguments for and against, including John Anstey who thought that hand dug holes are likely not to require a Party Wall Act Notice, whereas mechanically dug holes would. This may have been fair to say in days gone by but today we find that nearly all holes are dug mechanically so it is very difficult to know where to draw the line. We think probably the best comment here would be, subject to agreement, and the jury is still out as what legally is correct.
Does an impact driven pile require a three metre notice?
Strictly speaking it doesn't, but we are not aware of any surveyor that wouldn't serve one.
