is supplied for installation.
Additionally, each pile cage has a complex
internal cage structure including tightly
pitched helical and additional 40 mm rebar
to withstand the forces being applied to the
piles from the overlying structure.
All of the pile fabrication solutions were
trialled within the manufacturing plant to
ensure compliance with the specifications
and a safe and quality product was manu-
factured. Both Aarsleff and Centrum ensured
a transparent approach was adopted from
the outset and invited the client to witness
the factory and supported full production
Specifically, the works will include installing 174 piles
20m long and 350 mm square piles at Ditton, foundations
for a bridge. There will be 244 piles each 21 m in length
and 350 mm square at Victoria, which forms the foun-
dations for the approach viaduct to the new Mersey
Piling will be carried out using the company’s own
Junttan PM20s complete with high performance 7 t and
a 5 t hammer.
Speaking about the scheme, Stephen Black, Aarsleff’s
on-site Project Manager for the Merseylink development
“This is an exciting infrastructure project and
the first major highways project Aarsleff has
been involved with and where there has been
the provision of a dedicated resident Project
Manager in recent years.
“The use of raked precast engineered piles
overcame some of the many variable challenges
associated with the project, ranging from space
restrictions through to contaminated ground.
The challenging complexity of the scheme de-
manded a solutions-based approach working
closely with the client and client’s designer. “
The project construction works are being delivered
by a construction joint venture between FCC Construction
S.A., Samsung C&T ECUK Limited and Kier Infrastructure
and Overseas Limited, and is a continuation of works,
in which Aarsleff has been involved, with future works
expected to follow.
