Debbie Darling:

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 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, with values 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 innovations from BST’s ongoing Research and Development. . 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 cost-effective solution to our client’s foundation problems.

Core Competencies

• Large Diameter Rotary Bored Piles

• Secant Pile Walls

• Diaphragm Walls

BAUER Mobilises Rigs for Principal Place Residential Piling Works

2017-02-14T11:58:22Z

Debbie Darling:

BAUER Technologies, a subsidiary of the BAUER Group, has been awarded the main piling works design and construct package at Principal Place Residential in London, which is a new mixed-use development being developed by a Joint Venture between Brookfield Property Partners, Concord Pacific and W1 Developments.

This award by Main Contractor Brookfield Multiplex Construction Europe, follows BAUER’s successful completion of an Early Works package, where BAUER installed 25no. 1200mm and 1500mm diameter piles over 50m deep in secant pile walls. These piles have a combined structural function as bearing piles for a 50-storey residential tower and as retaining walls for the new Network Rail ‘8-track’ corridor. The installation of the Early Works was complex, requiring BAUER to work next to live Network Rail assets on a designed steel gantry structure constructing piles under bentonite. Working on a steel gantry demanded the use of bespoke piling rig configurations and rigorous adherence to agreed Method Statements. The Early Works scope also included coring of sub surface obstructions, forming guidewalls and the installation of 1800mm diameter bitumen coated, permanent steel liners.

With an overall contract value of £5million, including the Early Works, the main works scope requires BAUER’s BG40 and BG30 piling rigs to construct 27no. 1350mm and 2000mm diameter bearing piles under bentonite for the main 50-storey residential tower and includes the installation of 14no. large section ‘plunge’ columns. For the smaller structures BAUER will install 26no. 880mm rotary piles, while the 15-storey adjacent residential building will be founded on 36no. 900mm diameter, 27m deep CFA bearing piles. As the project will be constructed using a ‘top down’ method to form 3 levels of basement, the 150 linear metre site boundary is supported by a load bearing 880mm diameter secant bored pile wall.

The installation of ’plunge’ columns under bentonite in bored piles demands the use of a specialised temporary guideframe and careful execution of robust work plans at all stages of construction to achieve extremely tight tolerances. As part of the deployment, BAUER will use an ‘on-top reaming’ tool. This is a new drilling tool developed on a previous international BAUER project that is designed to maximise pile diameter where temporary casings are used.

The Principal Place Residential project, which commenced with Early Works in July 2015, is expected to be substantially complete by 2019.

Speaking about he project, Martin Blower, Managing Director of BAUER Technologies, commented: “This is an exciting and prestigious project for BAUER in the London Private Residential market. It requires us to construct piles to extremely tight tolerances in difficult ground conditions. The many challenges that the project presents also give us an ideal opportunity to demonstrate the capabilities of BAUER and our newly developed ‘on top’ reaming tool.”

BAUER delivers foundation solutions for Battersea Power Station

2017-02-14T11:56:02Z

Debbie Darling:

On behalf of its Malaysian shareholders, Battersea Power Station Development Company has awarded the Phase 2 piling works to Bauer Technologies, a subsidiary of the BAUER Group. Phase 2 of the Battersea development involves the restoration and refurbishment of the power station itself to create more than 250 homes, 500,000 sq ft of commercial use, 350,000 of retail, a food hall set within 6 acres of new riverside park. The main contractor for Phase 2 of the development is Skanska.

Developed by the Malaysian consortium comprising Sime Darby, S P Setia and Employees’ Provident Fund, the mixed use project will require Bauer to install over 600 no. bearing piles (diameters varying from 0.75m to 2.0m) up to 60m deep; (500 no. ‘dry’ piles and 100 no. piles under bentonite) together with 900 no. secant wall piles, all within the power station itself.

Bauer mobilised to site at the end of February 2016 to commence the Advance Works that involves the installation of the preliminary test piles and piling works for 2 no. tower crane bases, followed by obstruction removal work in advance of the start of the main works in June 2016.

Project challenges include the limited footprint available for heavy duty piling rigs and equipment, restricted access and, in places, restricted headroom when working around and under existing structures, removal of substantial manmade obstructions and the presence of a deep scour feature in the London Clay.

Speaking about the project, Martin Blower, Managing Director of Bauer Technologies, commented “This is both an exciting and extremely challenging project, requiring a variety of rigs on-site and the removal of a significant manmade concrete obstructions before work can begin. We are pleased and honoured to be awarded such a prestigious project. To ensure robust delivery, it’s of paramount importance that the right resource is available at the right time and by working collaboratively we anticipate and manage for all potential risk factors as the project progresses.”

BAUER Mobilises Rigs for A19/A1058 Coast Road Piling Works

2017-02-14T11:55:33Z

Debbie Darling:

Sisk Lagan JV, the Main Contractor grouping responsible for the A19/A1058 Junction Improvement project in Newcastle has recently awarded the piling scope of works for critical structures on the Highways England project to Bauer Technologies.

Work is now underway to create an improved A19/A1058 Coast Road junction which will support opportunities and economic growth in the North East. The £75m scheme involves the upgrade of the existing roundabout to an ambitious three-level interchange.

Bauer’s scope of works is to install 583 contiguous rotary bored piles with diameters ranging from 600mm to 1500mm. The piles, which are up to 31m long, are founded in sandstone bedrock to form contiguous pile walls, creating the trough for the future A19 ‘dive under’. A number of the retaining wall piles also act as hybrid design elements by carrying the load of three major single span bridges across the underpass. In order to verify the capacity of these critical foundations, Bauer will carry out three permanent pile load tests using the innovative Osterberg method.

The project is particularly challenging, as it involves Bauer working within a live, major roundabout with a heavy volume of traffic. In order to manage the associated risks efficiently, Bauer is working closely with SLJV and Highways England in order to implement stringent health and safety processes. In addition Bauer is enthusiastically participating in Highways England’s “Raising the Bar” scheme which is designed to raise standards in Efficiency, Quality and Health and Safety.

Piling works started in December 2016, with mobilisation of a Bauer BG30 rig, which will be followed by a second machine in early 2017. Piling works will be carried out in two phases and are expected to be complete by the end of 2017.

Speaking about the project Martin Blower, MD of Bauer Technologies, commented “We were delighted to be awarded this project, as it further demonstrates our capabilities in the Highways sector and strengthens our position as the major independent national specialist foundations contractor.”
