Mott MacDonald has extensive expertise in the design and
specification of settlement control measures such as compensation
and fracture grouting, jacking and traditional underpinning.
Drilling of grout injection pipes (TAM’s) from a
shaftIt is important to identify the appropriate set of
measures to protect structures or services from certain
construction activities. Otherwise the measures may, in themselves,
create as much or more damage than the main construction
activities.
Following an assessment of potential risks of damage to structures
and services a strategy of monitoring and protective measure is
developed.
Where deep basements are specified, substantial excavation support
is usually required. This may take the form of diaphragm or bored
pile walling, with strutting or ground anchors to control lateral
stability and structural deformations. Such support combined with
the overall method and sequence of construction is also critical to
the estimation and limitation of ground movements - a fundamental
aspect of soil structure interaction. In addition to a full design
service ranging from basic retaining walls to deep complex
multi-strutted sub structures, Mott MacDonald also offers the
associated geotechnical expertise in ground instrumentation and
monitoring.
