C0583 Knockmore To Lurgan Rehabilitation Project - Lidar Survey

Tender description

The railway line between Knockmore (south of Lisburn) and Lurgan consists of twin track railway with a maximum linespeed of 90mph. In areas actual speeds have been reduced by Permanent Speed Restrictions (PSRs) and further Temporary Speed Restrictions (TSR’s). Northern Ireland Railways Infrastructure Division are proposing a programme of works utilising track ballast rehabilitation methodologies. The Primary objective of the Track Ballast Rehabilitation Programme will be to return to, and maintain the operational line speed on the network to the design speed as a result of rehabilitated permanent way ballast. In advance of the ballast cleaning works, a LIDAR survey of the railway corridor will be carried out to cover the track bed, embankments and cuttings out to the railway boundary. In addition, a topographical survey of the track, up to 3m either side of the rails, will be undertaken. The topographical survey does not form part of this scope. Translink have included multiple options for the procurement route. The tender will be initially assessed using a combination of both Lots 1 and 2 as the commercial component. If the budget Translink has for this work is not enough to award a contract for both options the tenders will be re-assessed using Option 1 only. This contract will commence in November 2015 for a duration of 2 months.
