The Countryside Council for Wales is in the process of improving public access at Cors Caron National Nature Reserve (NNR). As part of this programme of works it is necessary to improve the surface of the old railway walk.

None

This track has been open to the public since 1967 following the closure of the railway.

The work will be carried out by a contractor.

Repair to potholes

All potholes are to be repaired along the bridge over the River Teifi to the entrance at Ystrad Meurig. A distance of approximately 800 m (See attached map).

The potholes should be cleared of standing water before filling. This should be done by baling or pumping.

The sides of all potholes should be excavated to give vertical sides before repairing.

Sub-base type II should be used as the fill. The contractor is welcome to suggest other suitable material.

Where a number of potholes occur in close proximity then the area should be excavated as a whole and resurfaced.

Resurfacing

A section of the railway of approximately 1,400x3m wide needs resurfacing. Only minor excavation should be needed to clear soil and mud from the surface. Excavated material can be deposited over the sides of the railway embankment - NOT on the verges.

100 mm of Sub-base type II shall be laid down and compacted. The contractor is welcome to suggest other suitable material.

The contractor will aim to make a cambered surface to shed water.

Before tendering, the contractor should make an appointment with the Reserve Manager. He/She should satisfy him/herself as to the full extent and character of the work and site conditions affecting the contract. The tender quotation should be for all the work necessary to complete the contract to the required conditions and specification.

The contractor shall prove that they possess a fully comprehensive insurance-policy to a minimum value of £2.000,000 to cover any claims arising from the CCW or any third party in respect of damage or negligence on the part of the contractor. A copy of the certificate must he sent with the tender. Unless previously supplied.

Site hazards: The contractor should carry out a risk assessment to the satisfaction of the CCW for the scheduled work. The work area is adjacent to a public access route within the NNR. Suitable precautions to minimise risk to public and staff should be taken by the contractor. A copy of the risk assessment must he forwarded with the tender.

The contractor shall carry out any mutually agreed variations or additional work after discussion with CCW staff. Both parties to the contract must confirm variations and any extra cost involved in writing.

The contractor can sublet or assign any of the work involved in this contract, but not without the knowledge and written consent of the CCW.

All requirements of the Health and Safety at Work Act 1974, and all relevant regulations and codes of practice must be adhered to. Failure to comply with this requirement will result in the job being stopped immediately and until such time as the contractor is able lo comply.

All users of chainsaws must hold the relevant National Proficiency Test Council competence certificate. Copies of certificates must be forwarded with the tender (Unless these have been provided previously).

All plant and machinery to be used for the work must have current certificates of worthiness where appropriate. Copies of certificates must be forwarded with the tender.

Vehicle access routes and use on site must be agreed with the CCW.

Suitable extra precautions such as warning signs and/or diversion barriers must be taken for sections of the work on or near public access areas of the site.

The railway walk is generally open to the public. So the contractor must ensure that appropriate safeguards are in place throughout the work.

Deep ditches and river channels that are liable to flood after heavy rain.
