Jones Bros Leading the Way
HEATHER WILLIAMS asks what do we know about a successful local business whose
vehicles we regularly see on the roads in North Wales
In September, we had an interesting visit to the Clocaenog area, where Jones Bros was at the final
stages of completing the installation of turbines for the new wind farm.
Founded in the 1950s by brothers Glyn and Elwyn Jones, Jones Bros is unique in having the in-
house expertise to take on some of the UK’s biggest civil engineering projects, while maintaining the
flexibility and personable approach of a family business. Operating from its head office at Tŷ Glyn,
the former ADAS and Denbighshire building off Park Road, Jones Bros now also has regional offices
in Swansea, Oxford, Inverness and Edinburgh.
The key areas in which the company specialises are renewables and energy, construction of waste
management facilities and landfill engineering, flood and coastal protection, marine infrastructure,
quarrying and aggregate production, highways and surfacing, and also infrastructure and plant hire.
Typically, Jones Bros works on joint ventures with other companies to undertake more complex
contracts—particularly in relation to wind farms and highway construction projects.
Renewables and Energy
In the 1970s, having established techniques for
constructing forestry access tracks, Jones Bros
was in an ideal position to help with the
challenging development of wind farms which
involved the construction of access roads to
accommodate abnormal loads, turbine
foundations, substations and electrical
infrastructure for on-shore wind farms.
Its largest contract to date involved 76 turbines at
Pen y Cymoedd in South Wales, as well as
others in the UK, and in particular in Scotland.
The Jones Bros website (jones-bros.com)
provides details of the location of these sites and
the dates when the sites were developed, as well
as contract values.
The company also provides infrastructure and
ground preparation for solar farms.
Construction of waste management facilities and
landfill engineering
From being a leading contractor for the
construction of landfill sites, Jones Bros has
become a specialist in the construction of waste
management facilities and waste recycling
plants. A local example of this is in Wrexham,
where Jones Bros has developed plant extracts recyclable material from domestic refuse and
transforms the residue into fuel for multi-fuel power generation facilities.
Flood/coastal protection and marina infrastructure
Jones Bros has tackled projects along the Welsh coast, to improve the coastal protection, some of
which have involved shoring up the sea defences with rocks, such as the Tywyn coastal defence
scheme. Other projects have included the Deganwy marina construction, Llanddulas jetty demolition
and the Terminal 3 development at Holyhead.
Quarrying and aggregate production
Jones Bros extracts and processes aggregates on site, reducing the need to import materials
required for highway and infrastructure work. It has one of the largest heavy plant fleets companies
in the UK.
Highways and surfacing
The company has worked on many major road contracts which have included construction of by-
passes, which have included the A5 Tŷ Nant to Dinmael rock cutting remedial work, the A487
Porthmadog by-pass, and they are currently working on the construction of the Caernarfon to
Bontnewydd by-pass.
North Wales Hospital
In partnership with the North Wales Building Preservation Trust, Jones
Bros is the preferred developer for the North Wales Hospital site, in
Denbigh.
Training & career development
Finally, the company offers supportive training and career
development opportunities. Rhys Roberts, the Site Agent who gave a
presentation to members of RADCA at the Clocaenog Forest wind
farm site is an excellent example. He joined Jones Bros in 2007
having been offered an apprenticeship after doing work experience
with the company while completing his A levels. After graduating from
the Civil Egineering Training Scheme, he has built up significant
experience while working on a number of renewable energy projects.
In 2015 Rhys completed his registration as an Engineering Technician
(EngTech) with the Institution of Civil Engineering (ICE).
He said “Jones Bros has given me plenty of opportunities to build up my skills and experience. I am
responsible for a number of duties on site, including the design and assessment of site tracks and
helping with controlling plant across site.
“I really enjoy my job, and love putting site plans into place so that you can see visible progress on
the project as the weeks pass by.”
So, in conclusion, it has to be said that we are most fortunate to have this forward-looking company
based here, which certainly is providing a sustainable future in the civil engineering field.

The Clocaenog Windfarm…
•
Covers 4,000 hectares
•
Originally was planned for 32 turbines but this was reduced to 27
•
Project has taken 10 years with planning permission granted in 2014
•
Construction work on site started in March 2018
•
Was originally due to complete on 5/9/19 but is now 2/12/19. Too much wind was main
problem in meeting the original date!
•
Project involved developing site compound, construction of 5 miles of roads, blasting stone
from local quarry, construction of concrete plant used for turbine foundations (72ft wide x
11½ ft deep) and electricity substation
•
Steel for cables is from Ireland
•
Turbines are from Denmark and transported by sea to Ellesmere Port thence by road
•
Blades are 167ft in length
•
Is shut down if wind speed is more than 55mph!
•
Electricity substation on site links to Scottish Power then National Grid at St Asaph
•
employed 1,200 people overall —75% of them being local
