Sligo Station

Project Description

Sligo Rail Station is a busy mainline rail station. In order to clean and paint the high level steelwork above the track and platform area it was essential to protect the train tracks from debris and to establish a strictly controlled safe method of working.

The work process involved:

· Protection of all tracks & surrounding amenities, with netting to catch debris

· High-pressure washing of steel work at 30,000psi

· Mechanical and hand cleaning of girders with grinders, needle guns, wire brushes and scrapers

· Spot priming

· Epoxy / polyurethane coating to required specification

Special Requirements

· Protection of rail traffic and workers on the line

· Working in a busy mainline rail station requiring strict safety compliance

· Working along live rail line with work stoppages for each train entering / exiting the station

· Close co-ordination with station personnel

· Cleaning and painting carried out from hoists above rail track

· Strict quality control involving third-party inspection

Enniscorthy Station

Roof Demolition

  • Removal of vegetation
  • Removal of existing slates, battens, fascia, barges, rainwater goods, timber decking boarding on canopy, timber rafters, asbestos gutter & rainwater pipes

New Works to Roof

  • Supply & fix new rafters / treated battens /pressure-treated decking boards /  roof slates / softwood soffit & barge / gutters / rainwater pipes / metal box gutters
  • Paint soffits & barges
  • Re-point loose stonework to southwest corner of  building

Remove Tree

  • Remove existing tree & carry out structural repairs to retaining stone wall

Waiting Room

  • Remove existing plaster each side of steel columns / clean down & de-rust steelwork / fix expanded metal & re-plaster / make good paintwork to walls
  • Re-point ridge caps

Re-Grinding of Tiles

Project Description

Cork, Limerick & Galway – Tile Re-grinding & Platform Marking

  • Remove broken tiles and replace with new to match existing – this process commenced 3-4 days before commencing grinding to give time for new tiles to set prior to grinding
  • Grind existing floor tiles to spec – this process needed to be repeated to achieve required spec.  Existing lines and stencilling were removed during this process
  • Sweep platforms to remove any flaking or loose material
  • Works areas fitted with masking tape as required
  • Apply temporary white line with temporary line-marking spray
  • Re-grout tiles & polish tiles
  • Once platforms are re-grouted and polished, apply chlorinated rubber paint to yellow and white lines, alternating with roller, brush, draw-box and spray-gun
  • Line out templates for new stencilling
  • Apply new stencilling using two-pack epoxy, applied by spray-gun
  • Dry lines and stencils with a blow torch if they have not dried adequately naturally
  • All areas to be left safe for passengers’ use at start of operational hours

Limerick – Step Nosings

  • Erect mobile barricade system at base of steps
  • Ensure stairs are clean, free of debris, dust, grease and oil
  • Mark out & drill for nosing fixings
  • Apply adhesive to the underside of the nosing
  • Screw stair nosing firmly into place, ensuring screws are flush to avoid show-through on the insert material
  • When works are complete, remove all excess materials and tidy up site

Ballynalty

Project Description

This is a five-span bridge over the River Shannon at Ballynalty in Limerick.  The bridge is 150 metres long with a total surface area of  5,500 m2 of steel.  The work process involved:

· Site set-up and complete scaffolding of bridge

· High-pressure washing 6000-8000 psi

· Grit-blasting to SA 2½ standard

· Priming

· Stripe-coating

· Epoxy / polyurethane coating to required specification

· Removal of scaffolding

It was particularly important that our health and safety policy functioned well during this project, as the work was carried out along an operating rail line.

Special Requirements

· Working in a tidal zone requiring a manned rescue boat at all times; working during full operation of passing trains

· Day and night shifts were necessary, increasing the risks involved and requiring flood-lighting

· Co-ordinating with other structural repair works being carried out at the same time

· Twenty-four hour security was required and this was also provided under our contract

· Strict quality control involving third-party inspection


Athlone Viaduct

Project Description

This bridge is the main rail access East – West across the River Shannon with an average of 33 train crossings each day.  The works involved:

· Site set-up and complete scaffolding of bridge with suspended, fully sheeted scaffolding

· High-pressure washing 6000-8000 psi

· Mechanical cleaning & shot-blasting of surfaces

· Epoxy coatings to complete steel structure of the bridge

Protection of rail traffic and workers on the line as well as fisherman, boats and other river and road traffic passing underneath the works was of the utmost importance. As Project Supervisor Construction Stage we developed and implemented a detailed works and safety plan for the contract.

Special Requirements

· Working above a busy waterway requiring strict safety compliance included a full time manned rescue boat

· Pollution control for waterway

· Working along live rail line with work stoppages for each passing train

· Day and night shifts were necessary, increasing the risks involved and requiring flood-lighting

· Night time road closures under bridge on one of main routes through Athlone town

· Strict quality control involving third-party inspection


Line Marking

Project Description

We have carried out line marking on platforms in many of Dublin’s train stations including Heuston, Connolly and Tara St stations. As these stations are operational 24 hours a day, planning and co-ordination of the works with Iarnród Éireann’s team is very important. Works were planned in advance, methods and work areas agreed and generally carried out at night. Renewal of line marking involves:

· Washing down platforms

· Removal of existing markings by chipping and grinding surfaces

· Priming surface where necessary

· Layout of marking with stencils or hand marking

· Application of line marking paint including

We have used M6 two pack line marking paint equivalent to liquid plastic coatings with 5 minute curing time.

Special Requirements

· Protection of rail traffic and workers on the line

· Working in busy mainline rail stations requiring strict safety compliance

· Working along live rail lines with work stoppages for each passing train

· Strict quality control involving third-party inspection
