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
