Tower Steelwork Assessments and LiDAR
Reference Number : S1186
Lot 1: Tower Steelwork Assessment:
Main Site : Throughout NORTHERN IRELAND.
NIE Networks has a requirement to carry out steelwork inspection and assessment of lattice towers. This relates to single and double circuit towers operating at 275kV, 110kV and 33kV.
NIE Networks intends to carry out refurbishment works to overhead lines on an on-going basis. Part of these works can include replacing corroded steel bars on towers due to corrosion, or to strengthen towers to carry larger conductors. In order to facilitate these works, it is necessary to individually assess the condition of each bar on the tower. Towers are graded 1-6 in accordance with National Grid Specification 3.04.31.
The appointed Contractor shall provide a complete service, whereby each individual bar is surveyed and photographed on site and assessed in terms of its condition. Data shall then be presented in summary for the tower as a whole. It is envisaged that the method of survey will be via helicopter or an Unmanned Aerial Vehicle (UAV) Drone. The tenderer should detail their proposed method. NIE Networks has no preference to which method is selected; however the tenderer should note Section 1.7 Inaccessible Bars within this specification and satisfy themselves that bars which cannot be fully surveyed will be taken into account during the evaluation process of the tenders.
It is assumed that the assessment element will be carried out in a desk-based environment using the images obtained in the field at an earlier date.
Bidders must have at least 3 years' experience of carrying out similar condition based assessments on lattice steel towers for other UK or Ireland electricity network operators. Previous experience must include assessment of at least 50 structures (or equivalent circuit length).
The contractor shall also hold all required licences, authorisations, training certificates and insurances to operate the drone/helicopter and to survey electricity equipment. As a minimum, this shall include either:
1) Valid CAA Standard Permission for flying small unmanned aircraft and provide CAA ID number;
2) CAA Exemption for low level powerline patrols by helicopter.
