A new Nuclear Advanced
Manufacturing Research Centre
(NAMRC) to be based in South
Yorkshire alongside the AMRC,
is currently under construction.
The new £25 million Nuclear
Advanced Manufacturing Re-
search Centre (NAMRC) led by
the University of Sheffield with
Rolls-Royce, will be based at the
Advanced Manufacturing Park.
Funding for the project com-
prises £15 million from the De-
partment of Business, Industry
and Skills and £10m from the
regional development agency, Yorkshire Forward.
Concrete specialist Richlea Developments are
main contractors on the scheme to install a new
horizontal boring machine within NAMRC’s existing
facility at Waverley Technology Park in Sheffield.
With the heavy foundations complete, the Re-
search Centre could install the large, heavy preci-
sion engineering equipment. The largest one of its
kind in a research facility in Europe, capable of ma-
noeuvring work-pieces of up to 100 tonnes in the
The bases required to support this massive ma-
chine are being constructed in a large excavation
using more than 1,200 m³ of concrete and over 100
tonnes of steel reinforcement.
The concrete foundations are supported by 78
auger-bored concrete piles, each 600 mm in diam-
eter and spaced at 2 m centres. These were drilled
from the underside of the existing floor slab before
work started to excavate the surrounding material.
The excavation, which is roughly T-shaped, meas-
ures approximately 35 m long x 18 m wide and var-
ies in depth from 3.1 m to 4.9 m.
Groundforce Shorco supplied the support sys-
tem, which comprised the company’s Mega and
Maxi braces with 900 Series braces of varying
They also supplied HY6 trench sheets whichwere
used to line the excavation whilst Piletec supplied a
MS4 EMV piling hammer to install them along with
a Taets pile breaker to cut down the concrete piles
to the required length.
Using a modular hydraulic bracing system mini-
mised obstructions in the excavation which was
crowded with the closely-spaced piles. Working
space was optimised by breaking the pile caps with
the Taets machine as digging progressed. In all,
about 5,000 tonnes of spoil was removed from the
