The Kells New Road Construction

Treffgarne, Pembrokeshire

Client: Tarmac National Contracting
Contract Value: £1.2m

The scheme was to improve a dangerous section of trunk road, approx 1km long where many accidents occurred historically. The road is the main trunk road to Fishguard Port, used heavily by lorries and HGVs and therefore required large scale investment to reduce risk.

The scheme scope Involved large scale earthworks cutting though fields to form a new section of road with many different elements to the scheme in addition to the road construction including:

  • Landscaping/Pembrokeshire hedge banks/steep embankments/fencing
  • Large diameter pipe for storm water drainage
  • Environmental/ecology works- Badger passes, silt fences where close to water
  • Extensive traffic management on busy trunk road which had permanent dedicated management presence

Management of the scheme was crucial with many activities happening simultaneously and a programme constantly under review. Resulting successful delivery depended on continual and effective communication between all stakeholders, commitment to meeting critical path of the programme and quality of work produced.

All concerned received widespread praise for the scheme.

This is a rather belated letter to thank your company and congratulate you on the above contract. We felt we had to write to tell you how much we appreciated the efforts your Company and men made. The new road both looks good and has done away with a very dangerous bend.

Westfield Pill Cycleway

Neyland, Pembrokeshire

Client: Pembrokeshire County Council
Contract Value: £180k

The scheme involved upgrading a section of the national cycle network by providing an improved link between a higher level route leading to the south of Pembrokeshire, and the low level Brunel trail which runs through Westfield Pill nature reserve.

Works were in an area where ecology and the environment were of upmost importance, with a sensitive approach to working being required. The brief by the client’s ecology department to ‘maintain a stable balance’ in the nature reserve was met but this provided to be challenging when undertaking construction works.

The scheme included Challenging earthworks/site clearance to facilitate the change in levels of the 2 sections of existing path which were to be married together other elements within the work scope included machine laid macadam path installed as cycle route with post & rail fencing; Stone faced reinforced concrete walls and innovative reinforced earth retaining structures (web walls).

The web wall earth retaining structures were designed with planting sections where specified types of flora and fauna could be planted to attract particular types of butterfly.

A further complication to the scheme included easements through the work required for access/potential maintenance for a high pressure gas line. There was a requirement within this for a licence to be granted upon approval of working practices and supervision of work activities.

Traffic management was required for a section which joins the existing cycle route alongside a busy A road.

There were many different stakeholders in the scheme- Constant liaison with Fisher German (fuel line management), ecology, local councillors.

We received positive comments from all parties on completion of the scheme including public appreciation with innovative construction techniques deemed extremely successful and are to be designed into future schemes.

Just to say how delighted we are with the new zig zag cycle path from the Brunel Cycleway to the bridge. It’s wonderful.

Cwmgwili Junction Works

Cwmgwili, Carmarthenshire

Client: Tarmac National Contracting
Contract Value: £80k

The works were undertaken for Tarmac National Contracting on the A48 between Cross Hands and Pont Abraham roundabout, to improve the safety of the main Cwmgwili junction and also improve the safety of the carriage way crossings along this stretch of road.

The works involved large scale road construction involving excavation of existing carriageways and new road layout being installed including large areas of kerbing and safety fencing works.

The works were of a high profile nature due to the time constraints imposed on the scheme and further complications such as co-ordinating with service providers and contractors as well as adhering and operating effectively and efficiently within the formal contract for the scheme.

The scheme included a very large scale traffic management element which was paramount to carrying out the works in a safe manner for both our work force and the public.

The scheme was completed on time and very much to the clients satisfaction and has ensured that fatal accidents on this stretch are greatly reduced moving forward.

Pensarn Roundabout Works

Carmarthen, Carmarthenshire

Client: Tarmac National Contracting
Contract Value: £400k

The scheme was to undertake the signalisation and re aligning of the large Pensarn Roundabout in Carmarthen which serves as a node point for the trunk road within South West Wales.

These works were of a very sensitive nature due to the need for a complicated and secure traffic management plan in order to make the work areas safe for both our work force and the road users, which inevitably caused some short term delays for road users. As a result, we alongside Tarmac National Contracting took the decision to undertake some of the more technical and disruptive works at night during the project thus easing the impacts on the traffic flows during peak times, which involved completely changing the proposed work methods and shift patterns.

The scheme involved co-ordinating with and installation of service providers and their utilities, large scale drainage incorporating an integrated system into the kerbing of the new roundabout layout, elements of excavation, working on road crossings co-ordinated with traffic management on live carriage ways and finally finishing works inclusive of road construction, slabbing and landscaping.

The scheme has now been in existence and operating over a number of years and has been a success in easing traffic congestion in and around Carmarthen, particular from the A48 approach from the East Wales side.
