Crossrail – Technical paper on Moorgate shaft base slab

As previously reported, Crossrail now has a Learning Legacy website dedicated to “the collation and dissemination of good practice, lessons learned and innovation from the Crossrail construction programme”. The material, consisting of case studies, technical papers, documents, templates and datasets, is being “shared for use by other major projects and is relevant to clients, corporates, and suppliers from main contractors to small and medium enterprises.”

Recently a technical paper was published on the Learning Legacy website about the design, detailing and construction of the Moorgate shaft base slab – a 1750 m3 pour carried out using Camfaud pumps.

The technical paper makes for fascinating reading, especially in regard to the pour preparations. As the paper concludes: “Careful planning of the concrete pour from reinforcement detailing through to road closures to give access to a constrained site in the heart of the City of London, the contingency measures for disrupted concrete supply and the control of concrete temperature led to the successful execution of what was at that time Crossrail’s largest concrete pour.”

Concrete magazine article – pumping heavyweight concrete

Crossrail C610 - Heavyweight concrete pumping

Crossrail C610 – Heavyweight concrete pumping

The February 2017 edition of the Concrete Society’s magazine Concrete, has an article about placing heavyweight concrete to form part of the Crossrail track slab in central London. The joint venture contractor installing the track on this project is ATC jv (Alstom, TSO and Costain), the concrete is supplied by London Concrete and the concrete pumping is being carried out by Camfaud.

Heavyweight concrete was considered the best option for this section of track bed in order to minimise the noise and vibration generated by the Elizabeth line when it is in service, especially in noise sensitive areas with recording studios above.

The heavyweight concrete used contains MagnaDense, a natural aggregate which is approximately twice as dense as normal aggregate. MagnaDense from LKAB Minerals is formed of black ferrimagnetic natural iron oxide (magnetite) and is mined in Kiruna and Malmberget in northern Sweden.

As the article notes, Camfaud Concrete Pumps chose a Putzmeister BSA2110HP static pump as the main pump, with another high-pressure pump being used as a backup and also to clean the lines using a water wash-out system. The concrete has been pumped through 1100m of pipeline, during which time there was approximately 40 tonnes of material contained in the line.

The same edition of Concrete magazine has an article about the new Medway valley crossing, built by BAM Nuttall to give access to the new 1000 home, Peters Village. Camfaud carried out the concrete pumping on this project too and further information about Camfaud’s work on this innovative bridge construction can be found here.

FORS Gold Award

Fleet Operator Recognition Scheme - FORS Gold Award

FORS Gold Award

We are pleased to announce that we have recently been awarded the Fleet Operator Recognition Scheme (FORS) Gold membership.

The Fleet Operator Recognition Scheme (FORS) is a voluntary accreditation scheme that promotes best practice for commercial vehicle operators. FORS encompasses all aspects of safety, efficiency, and environmental protection by encouraging and training fleet operators to measure, monitor and improve performance.

Congratulations are due to Richard Clark, our Plant & Transport manager, who manages the scheme for Camfaud, and to all of our pump operators, truck drivers and the drivers of our company vans and cars for their commitment to maintaining the highest driving standards.

For more information about this award, please visit the case study on the FORS website.

2016 – It Was A Very Good Year

Long distance concrete pumping - up to 1,100m

In 1965, Frank Sinatra recorded his classic hit “It Was A Very Good Year”. As we look back over 2016, we can certainly echo the sentiments expressed in the song title.

The year started with us moving into our new purpose built offices in our yard at Epping and ended with the announcement that Camfaud Concrete Pumps, South Coast Concrete Pumping and Premier Concrete Pumping had joined together with Brundage-Bone Concrete Pumping to create the world’s leading concrete pump hire group.

Our mobile boom pump fleet had a very busy year in 2016. We record the throughput of each of our mobile pumps so we can monitor the wear on the boom pipes and concrete pump wear parts. Last year our boom pumps pumped approximately 1,075,000 cubic metres of concrete. This is the first time that we had exceeded 1 million cubic metres of concrete pumped.

The highlight of the year, in terms of technical difficulty, has to have been the long distance pumping we have done using our static pumps. In 2016, we completed 43 pours that involve pumping though 500m or longer pipelines. The longest of these was in excess of 1,100m and several were around the 1,000m mark. If pumping that distance wasn’t difficult enough, 32 of the pours involved pumping heavy weight concrete. On the heavy weight concrete pours, at 1,000m, the pumps had to push around 44 tonnes of material on every stroke!

1000 Companies to Inspire BritainWe were gratified, in 2016, to receive recognition for our work from several diverse, external sources. Last year Camfaud was identified by the London Stock Exchange Group as one of the “1000 Companies to Inspire Britain”. We were also named as one of the “50 brightest and most innovative companies in Essex” by the Essex Innovation Programme. And Putzmeister, one of our two pump suppliers, featured our work pumping the concrete base for the British Airways i360, Brighton in a long article in the BAUMA edition of their Putzmeister Post and also in their 2016 Putzmeister Calendar.

And finally, 77,165 people visited our website in 2016 – including 102 on Christmas day, 5 of whom were considering applying for work at Camfauds!

Peel Ports Great Yarmouth – Outer Harbour Works

We have recently been working for Breheny Civil Engineering on their Outer Harbour works for Peel Ports Great Yarmouth. Breheny’s contract is for the construction of primary infrastructure and ground works for the offshore Galloper Wind Farm and East Anglia ONE Wind Farm projects. The contract includes the delivery of a yard storage and marshalling area, as well as the installation of heavy-lift quay facilities.

Last year, ScottishPower Renewables selected Peel Ports Great Yarmouth as its port of choice for the construction and installation activities for its £2.5 billion East Anglia ONE offshore wind farm.

The turbines for the project will be supplied and installed by Siemens, which also announced Great Yarmouth as the assembly and installation base for Galloper Wind Farm which is currently being constructed by innogy SE on behalf of the project partners.

(Camfaud have had another involvement with the Galloper Wind Farm project – pumping concrete for North Midland Construction on their contract to construct a new onshore substation to link the export cables from the wind farm to the National Grid.)

Siemens will supply 56 six-megawatt turbines for Galloper Wind Farm and 102 seven-megawatt turbines for the East Anglia ONE Wind Farm, which will have the combined capacity to generate enough energy for up to 836,000 homes a year.

To showcase the work that they have been carrying out for Peel Ports Great Yarmouth, Breheny commissioned a video which, shows a Camfaud boom pump working to construct an external slab for the yard storage and marshalling area. And, by happy coincidence, the video also shows our sister company Premier Concrete Pumping feeding a CFA piling rig of their customer Bachy Soletanche.
