Rosslare Europort Tower Remedial Works Completed

GRA Networks Ireland has completed a series of tower remedial works at the Rosslare Europort Terminal for Irish Rail.

GRA Networks Ireland were initially engaged to survey five existing towers at the terminal. Surveys and climbdowns were carried out to determine the general condition of each tower and to identify remedial works that should be undertaken to preserve the longevity of each tower. 

During the survey, towers 2 and 5 were found to have excessive corrosion and would likely require a major intervention, or be replaced with new tower structures. 

Towers 1, 3 and 4 were found to have medium levels of corrosion, however would require bolt replacement, descaling, painting and earthing.

GRA Networks Ireland used Jotamastic 90 as the paint coating, specially designed for areas where optimum surface preparation is not possible. The paint provides long lasting protection in environments with high corrosivity such as Rosslare Europort with a high level of exposure to weather conditions and the proximity of the towers to the sea.

The remedial works to towers 1, 3 and 5 were successfully completed and delivered to meet the outcomes of Irish Rail and the Rosslare Europort Terminal.

Four Year Mast and Tower Maintenance and Inspection Services Award

GRA Networks is delighted to announce that it has been awarded a four-year, multi-million euro contract with Iarnrod Eireann for the provision of maintenance services for approximately 204No radio masts, monopoles, and towers and 200No CCTV masts and towers including climbable, cantilever and fixed on the Irish Rail Network. 

The program also includes the rigging and cabling services to install GSM-R antennas and equipment on new towers and monopoles on the rail network.

Irish Rail were impressed with GRA Networks Ireland, considering that the company demonstrated a full understanding of the duties and procedures of a contractor working rail side and who could combine an end-to-end service for the SE&T department.

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.

GRA Networks Ireland deliver abseiling projects across a diverse range of industries. We offer a safe, secure, and competitive service, with a commitment to technical excellence and our worldwide reputation in telecoms contracting, we can work with clients to develop bespoke rope solutions that meet every requirement.

Mullingar AO Wall Remedial Works

Global Rail Services were contracted by ESB Telecoms to undertake remedial works on the boundary wall of their mast location in Mullingar. 

The project consisted of removing and relocating the existing power supply to the Vodafone cabin on site, demolishing the existing boundary wall and rebuilding the wall in-situ. 

This site was complex due to access constraints and limited space – Global Rail Services also had to maintain parking for the adjacent businesses during the construction works.

The existing wall had extensive cracks leading to structural failure of the drystone section. The failure was ultimately due to the internal compound level, which had been approximately 1 metre above the carpark level, and exerting pressure over time on to the base of the existing wall.

This project was successfully completed on time by the Global Rail Services engineering team to meet the clients expectations in terms of program, cost and quality.

Global Rail Services civil and structural engineering capabilities take full project responsibility and offer a fully managed and integrated service for Irish clients within the built environment.

The company provide civil and structural engineering solutions from initial project planning and design, to enabling works covering site surveys, hazard and environmental assessments, procurement, onsite construction and equipment installation, through to final commissioning.

The business has a flexible approach and can undertake civil engineering projects on a turnkey, consultancy, main contract, sub-contract or resource supply basis to meet each individual client’s requirement. Skills are applied to new build, refurbishment and maintenance projects.
