GRA Networks Ireland Delivers Abseiling Excellence

GRA Networks Ireland has completed abseiling contracts for three clients – namely Iarnrod Eireann, Imagine Networks and Vodafone. The company uses IRATA trained operatives to deliver this work.

Iarnrod Eireann – Drogheda Viaduct

Iarnrod Eireann required abseilers to install LED systems on Drogheda Viaduct. GRA Networks Ireland completed these works at night with a River Rescue boat in place for emergency recovery. Heavy LED lights were installed below the bridge which could only be done using an abseiling technique with the use of ropes. GRA then completed a second visit to replace faulty lights with the same scenario for a rescue boat. Faulty lights removed and hauled up to the top of bridge.  New light lowered and installed. All works done at night.

Iarnrod Eireann – Drogheda Viaduct

GRA Networks supplied abseilers to complete the successful installation of a new lighting system on Athlone Railway Bridge for Irish Rail.  Structural steel on the bridge was assessed for suitability prior to carrying out the works on a live railway during night-time hours under track possession.  GRA Networks Ireland liaised closely with Irish Rail and Waterways Ireland to complete the works. A rescue boat was in place on the River Shannon for the duration of the works.

Vodafone Ireland – Minch Norton

Vodafone contracted the GRA Networks Ireland team to install Antennaes and RRU’s at the Minch Norton grain silo site. GRA were required to rig and abseil off the side of a grain silo building to install Vodafone antennas and RRU. 

To accomplish this, GRA Networks installed stand-off steelwork on the side of building and created a safe work/drop zone below all works areas to ensure the wellbeing of staff and satisfactory completion.

Imagine Networks – Royal Hotel Bray

Imagine Networks engaged the GRA team in Ireland for the decommissioning of an antenna, RRU and cabling from the side of the Royal Bray Hotel building. A secure drop zone was initially erected below the area of the hotel. The area was very busy, so pedestrians were re-routed during the works. All works completed safely and efficiently and with minimal disruption to hotel.

Imagine Networks – RTE Donnybrook

Imagine required GRA Networks Ireland’s abseiling team to decommission and remove all antennas, cable management and cables from the Donnybrook Tower. All Imagine equipment was located 60 meters from ground level. GRA Networks set up the site and delivered an abseil solution that met the requirements without incident or accident and to meet the desired program.
