Firstly, apologies for plagiarising and modifying the post WW2 “export or die” slogan which was generally associated with the motor industry, in the days that we had we actually had one, and the need for foreign money to keep Britain afloat. However, in this fast paced digital age, I can’t help feeling that the principal of the adage applies as strongly now as back then.

This sequence explains the method for installing a Hydraulic Waler System, complete with optional End Bearers within a trench. Waler frames provide 2-way support to trenches and are used in conjunction with trench sheeting.

Hello and welcome back to the drawing board with me, Steven Lloyd. A few months ago I talked to you about the design of hydraulic struts and I mentioned that at the end of the strut there’s always this hydraulic unit now the reason it's there is so you can pump some fluid in and adjust the length of the props so they will always meet the size requirements.

Today we are going to take a look inside the hydraulic cylinder and see how that works. I’m going to start simple talking about single acting cylinder. This basically means that you can pump it out but you can’t pump it back in, strictly speaking.

Dublin-based Howard Building Contractors found itself facing a delicate problem when employed to build a new house on a vacant plot in Blackrock, Co. Dublin.

Once again welcome back to the drawing board. In the last couple of videos we talked about the design of equipment and the resistances of that equipment. We looked at the props and we looked at the wailers. Now we will have a look a bit at the other side, where the forces come from. 

Groundforce has taken its training capability to a whole new level with course additions and accreditations, one of which makes the company the only provider to offer such. Less than two years after opening the purpose-built training centre in Worksop, the company has won EUSR (Energy and Utility Skills Register) accreditation for its one-day course “Appreciation of Excavation Safety”. This is the course that only Groundforce can offer.

Welcome back to the drawing board and today are we talking about the design of walers as well as the combined effects that act upon them.  When I say combined effects I’m talking about axial force, bending moment and shear forces all acting on the waler at the same time. I won’t be talking about torsion because you don't usually see torsional effects on the kind of walers that we do.

 Following on from an earlier entry about the humble road plate, I thought I’d make a showcase of the often abused, manhole shutter. It may seem like a simple, primitive piece of equipment but even these simple tools have a raft of technical data and calculations to back them.

Considering that the shutter is, for the most part, just a 2mm thick sheet of steel, they are deceptively strong. This is primarily down to the way in which they carry the load from the fresh concrete within.

Prior to the adoption of Eurocodes in the UK, all the load capacity verifications and charts for our standard CHS struts were determined from BS 5950; EC3 although on the face of it, being a limit state code, is a natural progression from BS5950 however numerous detail changes exist within the document. 

To celebrate the Diamond Anniversary of Vp plc, Groundforce launched a competition to all readers of their seasonal e-newsletter.

For many years, Groundforce has been supporting young engineers by providing employment, training and education in many forms. Over the last five years in particular, we have sponsored a steady stream of budding engineers through university on a part time basis.

Following on from last month’s blog regarding preparations for the annual Ground Engineering Basement Conference; now this has been and gone and the dust settled, perhaps it is time to reflect on the event and to assess whether it has all been worthwhile.

After the summer’s “blog holiday” I am pleased put pen to paper again so to speak and report on our preparation for our headline marketing event; that is Ground Engineering’s Sixth Annual Basements and Underground Structures Conference; which is incredibly and rather worryingly less than a week away. 

In April’s technical blog I touched upon some of the basic principles of BIM and then started to look at what this could mean for our industry in general. 

When groundwater is likely to be encountered within and below an excavation, this generally means bad news for the designer at least due to a number of undesirable effects, including increased loads on supports, flow of material, boiling (see photo opposite) or heave of the formation etc.

Constructing a new building in a city centre requires a great deal of expertise if disruption to nearby residents and businesses is to be minimised. Speed and efficiency are key to getting the job done with the minimum of fuss and are essential to delivering the project on time and to budget.

This month I thought I would add a small introductory piece of the very topical subject of Building Information Modelling otherwise known as BIM. Grateful thanks to my colleague Dan Cuthbert for penning this blog.

British standards may come and go as do the latest industry trends and buzz words but how much has really changed in shoring in recent years? 

Apologies once again for not posting for a while; the best laid plans and all that. At least it’s good to be busy, or so they say! 2013 has already seen quite a few changes to the Groundforce Technical Department. A makeover of our main office, which has been looking a bit tired of late, has just been completed.

An unusually treacherous journey into work this morning reminds me that yet another year has flown by and the well earned and looked-forward to Christmas break is fast approaching.

Apologies for not posting for a while, poor excuse I know but the months just seem to fly by. For something a bit different from my usual offering, I have asked one of my technical colleagues Helen Aird to put something together along the lines of “a day in the life of a Technical Sales Engineer”. 

Following problems identified by the HSE regarding single pin connections to quick hitches, Piletec has worked with Miller UK to develop the best possible solution to the problem when working with Excavator Mounted Vibratory Piling Hammers. This research and development has taken some considerable time as Piletec considered that many of the "quick fix" fabrications offered by other suppliers actually create as many safety risks as they avoid.

After the brain ache sessions of the last two months blogging on thermal effects in struts, I thought it better to provide perhaps a gentler themed blog commensurate with the holiday season being in full swing. 

Last month we looked at the basic theory behind calculating thermally induced load effects in steel props. This month we’re going to attempt to bring this more into Groundforce’s arena by applying these theories to one of our modular hydraulically operated props.

Continuing last month’s technical theme, this month’s blog discusses another old chestnut; the effect of ambient temperature change (thermal effects) on hydraulic struts. 

Why do we so often apply the 45° rule of thumb for the influence that surcharges have on the design of excavation support?

Miller Piling needed to install a total of 1500 concrete piles on two major high profile projects in the centre of London, one residential and one mixed use. Although in close proximity to each other, both projects had different and equally challenging ground conditions to contend with. Having worked with Piletec previously on a number of projects, Miller chose to hire two Free Suspended Vibratory piling hammers.

Apologies for not posting for a while but an exceptionally busy end of year placed great demands on the technical team. It’s nice to be busy or so they say!

With a welcomed boost in activity over recent weeks, I thought this month we would give you a whistle-stop update into what is going on within Groundforce`s European adventure, an overview of some of the projects we are working on at the minute and even show you some pictures of our equipment in the ground.

For those of you who have been on tenterhooks since the basic principals of hydraulic struts entry back in March, your wait is finally over as in this edition I intend to take it one step further and delve into more advanced workings of hydraulic struts.

Firstly apologies for not submitting a blog entry for a while, must be a sign of my age but the months seem to fly by particularly when you have to compile a monthly departmental report! 

Construction of a major new hotel on London’s South Bank has required the excavation of a large two-level basement in poor ground conditions in an extremely built up location. The main contractor is GTM, a joint venture between McGee and Galliford Try, which has taken the unusual step of eliminating the use of subcontractors wherever possible.

I know last month’s entry promised you more on the principals of hydraulic struts, however there has been so much going on in the technical camp since my last transmission that I thought it might be preferable to hear about that instead……. so you’re just going to have to wait a little longer before we get back on with the joys of pre-stress!

I thought that this month I would take the opportunity to go back to basics and give a brief insight into how Groundforce propriety equipment operates and to try and explain what is actually going on within the struts when you get to work on the hand pump, or when you simply flick the lever on the labour saving motorised pump.

The second Tyne Tunnel is a £260m scheme to alleviate traffic congestion through the existing single lane each way tunnel bore. It is one of the largest road infrastructure projects in the UK in recent years. The Tunnel, due for completion in 2011, is being constructed by French contractor Bouygues mainly using traditional cut-and-cover techniques on the North and South approaches and immersed precast concrete tunnel segments sunk into the river bed for the tunnel itself.

After a well deserved festive week off, followed by the usual slow first week back, construction sites are starting to make noises again and 2011 is underway, and at pace!

As the end of year fast approaches and the wind-down begins in earnest (hope the MD does not read this!), there is a definite change in the mood of the camp here in the technical department; the telephones ring less often, the number of new projects starts to dwindle, staff rush to use up their remaining holiday entitlement and the seemingly never ending supply of sweets and cake from kind suppliers becomes available.

Value engineering (VE) is a current buzz phrases within the industry. It is a systematic process which either identifies and eliminates unnecessary costs or increases utilisation.

The latest development in proprietary support systems is the ability to equip struts with integrated wireless load monitoring capability. 

The initials “SWL” are one of the most easily recognised and understood acronyms in the construction industry; you know that something marked “SWL 5 Tonnes” can safely support a maximum load of 5 tonnes in real terms.

Construction of an unusually wide basement box in poor alluvial soil requires exceptional lateral support for the piled retaining walls. The traditional method of bracing such an excavation is to install a specially designed framework of structural steel – a method which is both expensive and time consuming.

The Limerick Tunnel is a E570 million public-private partnership scheme for the Irish Republic’s National Roads Authority. Designed to carry four lanes of traffic under the River Shannon, it forms the centrepiece of a major by-pass project for the city.

Groundforce Shorco have provided a unique ground support solution to Barhale Construction for a flood alleviation scheme in Gloucester.
