Geotechnical Services File: Strengthening market

Trevi mosul

Ground engineering is always the first to be affected when a downturn in the market hits because its work is focused on the early stages of construction but as a result it also always the first to recover too. Figures for the 2016 Geotechnical Services File (GSF) suggest that the UK ground engineering sector has not only recovered, the size of the market is now 20% larger than it was before the recession hit in 2008. 

Turnover reported by the top 35 UK geotechnical businesses for the GSF in the last couple of years has been around the £1bn mark – a level previously last seen in 2007. This year the same group has reported revenues of over £1.2bn and forecasts undertaken for the survey suggest that there is potential for continued growth in the next 12 months.

It is not just the top businesses that have seen improved turnover in the last 12 months either. In order to gain a place in the top 100 UK geotechnical businesses listing in 2015, companies needed a turnover of £0.5M or more. In 2016, just one business with a turnover of under £1M made it onto the top 100 listing. For the last few years the combined revenue of this group has hovered at around £1.18bn but this year the result for the top 100 is £1.47bn demonstrating the change of pace at all levels.



Although the growth has been widespread, the fortunes of the top companies has differed resulting in some changes in the top 10 this year. Bachy Soletanche has retained its lead position with a turnover of £92.6M up from £87M reported last year. Balfour Beatty Ground Engineering’s (BBGE) £10M improvement in turnover to £81.3M has seen the company move from fourth place last year to the number two slot in the 2016 GSF.

BBGE’s gains have knocked Roger Bullivant and Van Elle down to third and fourth position, respectively, despite modest gains in turnover by both over the last 12 months.

Fifth place this year goes to Cementation Skanska, which saw its revenues recover from the post-Crossrail boom low of £45M reported last year to £72M this year, which is more in line with the company’s normal performance.



New into the top 10 at sixth position is Aecom – the leading consultant in the listings – with a turnover of £67M. Last year Aecom only reported global figures for its geotechnical turnover and its buyout of URS in late 2014 meant that it could not incorporate or report on the UK turnover in time for the 2015 GSF, so it did not appear in the rankings last year.

The return of Aecom has knocked Bam Ritchies and Keller down to seventh and eighth places despite a respectable rise in revenues to £61.9M and £59M, respectively.

International growth and decline

International growth and decline

Fugro appears to be the only business in the top 10 that has seen revenues drop over the last 12 months. Last year the business reported a turnover of £66.5M but this year it has reported sales of £58M.

The final place in the top 10 is taken by a newcomer to this end of the market – RSK Group – with a turnover of £42M this year compared to £19.5M reported in the 2015 GSF.

Just outside the top 10, there were some other notable improvements in financial fortune over the last year. One of the biggest improvers is Keltbray Piling, which moved up from 16th position last year to 12th this year with an increase in revenues from £20M to £35M. If forecasts from the business bear fruit over the next year, it is likely that Keltbray will be muscling in on the top 10 in 2017.

Increased demand in the driven piling market also boosted Aarsleff Ground Engineering from 24th place to 21st with a 50% increase in turnover to £21M reported this year. Arup only moved from 12th place up one position to 11th but it was a 25% increase in revenues to £40M that drove the change, significantly outperforming growth reported by other leading geotechnical consultants.



While the rise in revenues is good news, there is still concern over small margins in the ground engineering sector with over 35% of respondents reporting this to be an ongoing concern for their businesses. 

Past performance

Many of the companies that weathered the recession well were beneficiaries of the Crossrail boom but that source of work is mostly in the past. Although new infrastructure schemes are coming on stream, or are expected to in the near future, the growth of the last 12 months has largely been driven by other parts of the market.

“The market this year has mostly been dominated by commercial contracts but next year the focus will shift more to infrastructure work as some major projects get underway,” says Bauer Technologies managing director Martin Blower.

Salary survey

“We have seen a slowdown in the commercial sector in recent months though and I think this is due to investors becoming nervous over the Brexit decision. Prime developers want certainty before committing and we’re seeing the same hesitancy as we saw last year ahead of the general election.”

Keller managing director Bob Thompson adds: “Up until 18 months ago the market was 30% private and 70% civils but that has now switched. The private sector is much more competitive but I believe it is still buoyant at the moment and hopefully it will continue that way until the expect civils pipeline comes on stream.”



Bachy Soletanche managing director Chris Merridew has also seen commercial work overtake infrastructure: “Over the last year we have seen a reduction in the number infrastructure projects with Crossrail and the Lee Tunnel works moving into a different phase, but there has been an increase in the commercial market, particularly at Canary Wharf and in the City. However the high rise residential market has been very strong over the past year, particularly within the M25.” 

The Brexit effect

The GSF survey and interviews for this analysis were undertaken ahead of the EU Referendum in June but it was clear that the vote was already having an effect on the market and, whatever the outcome, it would continue to affect demand.

Construction industry forecasting business Glenigan reported in early June that there had been a sharp fall in the number of new project starting on site in May, which it attributed to the Brexit vote.

Merridew says his firm was already seeing a slowdown in schemes being turned into awards in the two months before the referendum as investors/developers waited for the decision. This uncertainty will continue for some time as the new political environment is defined.

Several industry leaders warn that it will still take time for investors to regain confidence and start awarding work as was seen after the general election last year.

There are also concerns that the vote to leave could add to the skills shortage issues (see box) that the UK ground engineering industry is facing.

Market prospects

Again it is worth emphasising that the GSF survey were undertaken before the EU referendum. But with a clear upturn in the geotechnical market in the last 12 months, many were optimistic for continuation of this trend. Just 1% of respondents to the GSF survey expected workloads to decline in the next 12 months. There is much greater confidence in further growth with 62% expecting workloads to increase, which is in line with the 67% who predicted an increase in the 2015 GSF.

“The forward pipeline of infrastructure investment is encouraging,” says Arup director and global geotechnics skills leader Nick O’Riordan.

He sees the main opportunities in the next 12 months coming from growth in the highways sector, rail upgrades and High Speed 2, as well as projects involving deep geology.

Regional growth decline

Merridew adds: “There are a number of large projects starting in the next 12 months. Works will start on the three main works contacts at Thames Tideway starting with the main drive shafts. There are also a number of hot spots, in London for instance, with ongoing works and with further works planned, Nine Elms, Kings Cross, Olympia and Shepherds Bush, and Canary Wharf for example. We are seeing an increase in schemes between Leeds, Manchester and Birmingham.”

According to Beales, major projects will dominate the market in the next 12 months and he sees good growth potential ahead for both large and small players in the market.

Sector growth declines

Sector growth declines

Respondents to the GSF expect the main growth in geotechnical work to come from the rail (59% of respondents), energy (46%), private residential developments (44%) and roads (40%) markets. Few are predicting declines but around 16% of respondents expect retail work to decline over the next year with other expecting a fall in demand from the education (10%) and private residential (9%) markets.

In terms of where the growth and decline will happen on a regional basis, significantly more respondents predicted growth than decline across all regions. The main regions expected to grow in the next year are London (54% of respondents), the south east (41%), the north west (37%) and the Midlands (36%).

Procurement approach

With the infrastructure market gearing up for major investment, a number of businesses have reported seeing a change in approach to procurement.


Staff number growth

“We have seen a change in the behaviour of clients in the last 12 months,” says Aecom head of ground engineering in UK and Ireland Stephen Beales. “They are now more focused on the relationship with project partners rather than on the price or quality as they were in the past. Clients are now more interested in the behaviours of their partners and whether the companies they work with share their vision.”

Beales believes that this shift is a benefit for businesses like Aecom, which have a defined way of working.

Combined service offering

“Clients are also looking for a combined service offering,” he adds. Nonetheless, Beales still believes that there is room in the market for smaller, independent consultants as businesses like his “can’t compete on the smaller schemes”.

Nonetheless, the change is having an impact on SME businesses, according to Byrne Looby technical director David Beadman. “As an industry there are lots of SMEs in geotechnics but the current approach to infrastructure work seems to exclude this part of the market,” he said during discussions at the recent GE Infrastructure Summit. “I am not sure how that could be changed but these major projects are missing out on the expertise in the early stages and we only seem to get brought in in the latter stages to deal with specific issues.”

Risk management

The change in procurement practices is also bringing a change in the way clients expect the supply chain  to manage and accept risk. Excessive risk transfer has long been a concern in the ground engineering market and around a quarter of GSF respondents said they are worried about how this will affect business in the next 12 months. 

The way the industry is working is also changing with 38% of respondent reporting an increased use of BIM in the last 12 months. Around a quarter of respondents are now using it on a regular basis and a further quarter working on adopting BIM practices.

Speaking at the Summit, Atkins practice director for ground engineering David French said: “There has been a huge acceleration in the technology that is being used. We still need people to deliver project but geotechnical people need to be adaptable to change. Technology will change the way we work significantly in the next five years.”

While the way work is delivered may change over the coming years, what is clear is that there is a strong pipeline of work ahead and, for the first time in many years, it will be spread across multiple sectors.
