BAUER Technologies is the UK contracting arm of the BAUER Group. We perform deep foundation works
on major projects in the UK. We specialise in the design and installation of large diameter piles, diaphragm
walls, under-ream piles, plunged column piles and in-situ piled retaining walls.
The BAUER name is synonymous the world over, with the highest standards in
foundation engineering. By concentrating on our core competencies we are able to
ensure we maintain these high standards in the UK. We specialise in major projects,
value in excess of £500K, and technically complex projects.
All our piling and diaphragm walling equipment is manufactured by BAUER. This
equipment is particularly suited to dealing with hard strata, including the removal
of reinforced concrete obstructions where these obstruct the position of a proposed
foundation.
As a wholly owned subsidiary of the BAUER Group we are fully supported by the
technical departments of our parent company BAUER Spezialtiefbau (BST) in
Germany, allowing access to additional rigs and specialist resources as well as
enabling us to benefit from the latest improvements from BST's Research and
Development department. By maintaining close links with our worldwide network we are able to draw upon
the full depth of BST's experience and engineering knowledge to develop the most innovative and costeffective
solution to our client's foundation problems.

1. Palm Paper Project, Kings Lynn
BAUER Technologies performed the contract for the piled foundations of Europe's largest paper
machine. The scope of the project was to install a secant pile wall (hard/hard) and foundation piles
to support the machine hall area to a design developed by BHM INGENIEURE Engineering &
Consulting GmbH. The final value of the works performed by BAUER amounted to £4.4 million.
2. Waste to Energy Facility, Newhaven
BAUER Technologies executed a diaphragm wall and foundation barrettes to a circular shaft for the
facility in Newhaven for Hochtief UK. Different options and alternative technical solutions were
proposed and offered during the tendering phase before Hochtief, in joint venture with vonRoll
(Switzerland), awarded the project to BAUER Technologies Ltd.
3. Severn Power CCGT, Newport
BAUER Technologies were awarded the £15 million contract for the piled foundations of the new
Uskmouth Power Station which consists of two power generating units, each a variety of structures
covering an area of 60,000sqm. The scope of the piling contract involved the construction of the piling
platform, a preliminary pile testing regime, the erection of an on-site concrete batching plant, the
installation of the piled foundations, comprising 439nr 620mm diameter bored piles, 426nr 880mm
diameter bored piles and 711nr driven cast iron ductile piles.
4. Pembroke Power Station, Pembroke
BAUER Technologies completed the £5 million contract for the installation of the piled foundations
at Pembroke CCGT. Each unit consisted of a variety of sub-structures covering a total area of
40,000sqm. The scope of the piling contract comprised the construction of the piling platform,
preliminary trial bores to verify ground conditions and rock head level in the piling area, a preliminary
pile testing regime including a fully instrumented test pile, construction of 2,307no. 600mm
reinforced CFA piles, 421nr 900mm unreinforced CFA piles and installation of 10nr 1200mm diameter
steel liners to 10m depth at the condensate pit, including all associated piling attendances.
5. Pembroke Jetty, Pembroke
BAUER Technologies completed these extremely complex works on a 50 year old jetty on the
Severn Estuary at the site of the new 2000MW, Combined Cycle Gas Turbine Power Station, to support
the Leibherr LGD 1750 and its 387.5 tonne superlift required for the safe off-loading of five 400-
tonne turbines as part of the stations' construction. BAUER chose its rotary system for the job, using
thick walled casing with tungsten carbide cutting teeth rotated to toe using BAUER's powerful BG28
rig. For the marine piles, 1220mm diameter casing (19mm thick) was fitted with BAUER spec
cutting teeth to ensure penetration through the boulders.
Work was undertaken 24 hours a day, 7 days a week to complete the piling and ensure that the tight
deadline was met as the ships in Rotterdam were on equally tight schedules to depart.
6. Tottenham Court Road Station Upgrade, London
BAUER Technologies performed large diameter (2m+) piling down to below 65m deep, diaphragm
walling 1m thick x 41m deep, 11nr plunged columns installed into large diameter 48.5m deep piles
of diameter 2.4m and various secant pile walls. The project included numerous challenging
operations such as;
- Construction of a 2m diameter bearing pile with permanent liner in a 'D Shape'.
- Design and installation of a new bespoke plunged column frame 23m long equipped with laser
guides which for the first time in the UK bears on naked soil rather than a steel casing clamping the
frame in place. The plunge columns are by far the heaviest and longest that the industry has seen
for a while with a mixture of 600 x 600 and 700 x 700 columns up to 33m long installed.
- Installation of a diaphragm wall within a working area of 25m x 30m surrounded by London traffic.
Project value £18.9m in JV (BAUER portion £14m). Main Contractor Vinci Bam Nuttall JV. Client
London Underground.
7 & 8. Whitechapel and Liverpool Street Stations
BAUER Technologies have been successful in securing two Crossrail Advance Work Stations at
Whitechapel and Liverpool Street, for main contractor Bam Nuttall/Kier JV. The contracts consist of
Diaphragm Walling, Large Diameter Piling, Pile Removal and Barrettes. Wall thickness reaches a
maximum of 1.5m, with depth reaching 60m. Combined contract value £25m.
