Project under construction
The new North Runway project in Dublin Airport is the most substantial airfield project in Ireland for a long time, and upon completion it will become a vital piece of national infrastructure, significantly increasing the capacity of Dublin Airport. Mainline are the Lead Electrical Contractor on this large scale Aviation project, and our scope includes the supply and installation of the following:
Project Completed: 19th of October 2018
The scope of this project included the supply and installation of a new MV cable to replace a 30 year old MV ring around the Airfield in Dublin Airport between Substation “A” and the West Substation.
The project was broken up into the following three segments. Each leg was to be upgraded on a phased bases in order to minimise disruption to the network. The three segments were as follows:
Mainline Power completed the following as a part of the project:
Civils Works
Electrical Works
At all-times one portion of the MV was required to be maintained and operational.
Project Completed: 24th of July 2018
Runway Guard Light systems were required in Cork Airport to improved awareness of an active runway
and to mitigate unauthorised entry to the Runway.
This project includes all electrical and civil works for the installation of additional Runway Guard Light
systems for Nine Taxiway/Runway and Runway/Runway intersections as detailed below:
Mainline Power completed the following as a part of the project:
Civils Works
• The cutting of saw cuts for secondary cable routes
• The construction of secondary ducting from new fitting location to way edge (saw cuts) including provision of ropes.
• The setting out and installation of concrete bases to house the new 12” shallow base pots in existing pavement
• The Sealing cable chases upon installation of all secondary cables.
• The coring and breaking out for new inset shallow bases
• The setting out of ducts, chases and shallow bases for AGL fittings
• Delethalisation works
• Quality Audits on inset fitting adhesive materials
Electrical Works
• Installation of free issue Primary Cabling (4 # 6.6 amp series Circuits) into existing ducts to feed all new Runway Guard Fittings – 10km
• Installation of new concrete bases to house new 12” shallow base pots
• Installation of free issue Shallow pots in 12” cores for Runway Guard (Configuration A)
• Make up and install new secondary cables, (including earth cable) via new saw cuts and ducts.
• Installation of free issue elevated Runway Guard fitting (Configuration A) into existing/ new shallow pots – 18 in total
• Supply and installation of labelling on all fittings, cables, transformers and manholes in accordance with the drawings
• Installation of free issue CCR’s into existing switch room,
• Supply and Installation of all accessories associated with the installation of the CCR’s including all LV cabling, PLC cabling, MCB’s, cable distribution etc.
• Test and commission AGL systems.
• Carried out Insulation resistance tests on all MV (FLYCYs) primary circuits at Substations prior to working on these circuits, measured and recorded results for comparison with identical tests carried out after works to confirm that no attenuation of the resistance of the circuit insulation occurred during the works.
The 28th of March was a major date for the D.A.A. as this was the date the re-designation took place of all the taxiways airside at Dublin Airport.
This project involved the installation of new taxiway signage to be ready for the implementation of the re-designation of the airfield in the locations.
Project Completed: 28th of March 2019
Mainline Power completed the following as a part of the project:
• Provided new cores on the existing/new concrete bases.
• Made safe, disconnected and salvaged existing signs including associated secondary cable (plug and socket) fly-leads. Signs were strip-out and returned to the DAA for refurbishment. The leads were held for reuse.
• Made up and installed new secondary cables (and earth cable) via existing ducts and connected them to the existing isolating transformer. Reused the leads previously stripped out.
• Made 20mm hole on the leg to allow the leg to be used as a raceway for the secondary, Arctic Blue cable thus providing mechanical protection form rodent damage.
• Cables were repositioned to suit the existing infrastructure.
• Installed new illuminated signs on existing foundations.
• Supplied and installed M12 fixing bolts for securing legs of the signs to the plinths.
• Supplied and installed earth rods and earth rail etc. in manholes.
• Supplied and installed transformer brackets to support transformers on the walls of the manholes.
• Supplied and installed labelling on the signage circuit fittings, cables (secondary cables) and transformers manholes in accordance with the drawings.
• Carried out Insulation resistance tests on all MV (FLYCYs) primary circuits at Substations prior to working on these circuits, measured and recorded results for comparison with identical tests carried out after works to confirm that no attenuation of the resistance of the circuit insulation occurred during the works.
Project by Numbers:
• 146 Signs Installed
• 389 Signage Legs Supports Installed
• 146 New Transformers Installed
• 584 Secondary Joints Completed
