■ Acceleration and lean efficiency;
from concept to site delivery inside
12 months, prioritising only the
most critical works.
■ Renovation means reviving and
making assets sound again as new
for the 21st century, using
innovation, economics and whole
life design. In other words, it’s not
simply a full rebuild.
■ Utilising network outages efficiently
to access the most vulnerable parts
of our UK network.
■ Boosting UK engineering resources
and capability, i.e., competent and
trained professionals.
■ Standardisation of work scope,
modular off-site build and economies
of scale.
■ Resolving work backlog and deliver
