Monopole Tower and Civils Project Completed in Cork

Global Rail Services has been commissioned by Irish Rail to complete the installation of telecoms towers and monopoles including associated civils and electrical works to facilitate the roll out of the GSM-R project as part of the GSMR 3A Civils works package 2 on the Dublin to Cork railway line for Irish Rail. 19No sites in total were completed by Global Rail Services.

As part of this major program of the works, the team at Global Rail Services has recently completed a complex 15m monopole tower project in Cork.

Due to the limited area on site, a large bulk excavation was completed, which then required an engineering retaining support system to be installed prior to commencement of the Mast base location works at this site. This consisted of a large gabion basket structure to retain the existing ground profile prior to the start of the excavation.

The 1.5m excavation was completed adjacent to the rail line under lookout protection, 3m away from the running rail. Global Rail Services installed a 300mm lean mix layer below the base. The steel reinforced foundation cage was installed on site – 3.5m x 3.5m and 1.2m deep. Peri shutters were used to cast the foundation base. All concrete on site was pumped.

All associated ducting for ESB and fibre works were completed as per specification. Fibre works were completed at night under T111 possessions, road railers and rail dumpers were used to install 2No precast JB4A manholes and 45m of ducting over existing fibre, which was completed to connect to the Irish Rail network based in NTCC in Dublin.

Palisade fencing and gates were also completed to create a standalone Telecoms compound.

A crane hard standing area was then constructed to lift the new Monopole into location. Our rigging team completed installation of the 15-metre monopole, which due to the proximity of the track and the requirements for safe working was installed during a TIII absolute possession of line. This element of the project was completed by sister company GRA Networks Ireland (GSMR crews) under the supervision of Michael Ging.

As the team exited the site, they undertook landscaping works, which included planting trees, topsoiling, and seeding.

The works were delivered by our team which included David Byrne and Ger Delaney and were expertly organised, planned and coordinated by Senior Project Manager Damien Carroll.

Ballast Containment Rail Project at Portlaoise Completed

Our Irish business – Global Rail Services – has completed its ballast containment works contract at Underbridge UBC161 in Portlaoise, for client Iarnród Éireann – successfully meeting the desired program and project outcome. The project was completed under a TIII absolute possession over an intense 4-week period – based out of Kilbricken Depot.

The significant ground engineering scope included installation of 77No Ischebeck Titan mini piles followed by 80m of galvanised ballast retention units and guard rails.  During the project Irish Rail implemented a speed restriction, reducing the 100km/hr line down to 50km/hr during the day – enabling one line to be completed at a time.

This successful project was a real team effort, with Irish Rail staff working collaboratively with Global Rail Services teams to complete these works on an extremely busy line. Global Rail Services were ably supported by supply chain partners Mannings Engineering, MDH and Breffini/Dixon Bros.

Special thanks also to Stefan Aspatartei and Stelian Poiana who delivered the project from start to finish, helped by Ger Delaney, David Byrne, Ollie Brenan and Mario Baciu.

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.

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.

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.
