Summary

Roughan & O’Donovan-AECOM was appointed to provide technical consultancy services for the Athy Distributor Road project in April 2015. Our appointment covers all stages of the project, including detailed design, procurement, construction supervision and contract administration.

The project involves the construction of a 3.4km single carriageway distributor road around the southern side of Athy, largely following the line of the disused Athy-Wolfhill railway. The route crosses the River Barrow, a Natura 2000 site that forms part of the River Nore and River Barrow Special Area of Conservation. It requires the construction of an 80m single-span steel composite bridge across the River Barrow and a two-span bridge over the Dublin to Waterford railway line.

The design incorporates extensive improvements to pedestrian and cycle facilities, including the repair and repurposing of a listed, disused railway bridge over the River Barrow as a cycleway/footway. Dedicated links will be provided to the Barrow Way, a long-distance walking trail that follows the original towpath of the river, and to Athy Railway Station.

Solution

Traffic patterns

ROD–AECOM developed both macro-simulation and micro-simulation traffic models to assess the optimum solution to traffic congestion on the N78 through Athy.

Constraints and route selection studies

We undertook constraints and route selection studies of routes to the north and south of Athy, which were assessed in accordance with the Common Appraisal Framework headings of economy, safety, environment, integration, accessibility and social inclusion.

Preferred Route

Following the publication of the Route Selection Report in August 2016, we further developed the preferred route.  This culminated in the publication of the Environmental Impact Statement (EIS), Natura Impact Statement (NIS) and Compulsory Purchase Order (CPO) in April 2017. 

Planning

ROD-AECOM provided expert witness testimony in support of the proposed development at an oral hearing, which took place in July 2017.

In October 2017, An Bord Pleanála granted planning consent and CPO approval for the scheme without the imposition of any additional conditions. 

  • We have not read such a superbly crafted witness statement that dealt with the submissions/objections in such a seamless manner. It should be a template for everyone going forward.

Challenge

The River Barrow SAC

Developing a bridge solution that minimised impacts on the qualifying interests of the River River Barrow SAC represented a challenge.

Asbestos materials

Athy has a manufacturing past that produced asbestos materials, and there are a number of known asbestos disposal sites in the town.  During the route selection phase, the known sites were identified, and the route options were designed to avoid impacts on these sites. 

The ground investigation works undertaken as part of the preliminary design sought to determine the extent of a known asbestos disposal area located adjacent to the scheme and whether any previously unknown sites existed along the route. 

Latest developments

Works have been progressing in Athy, with an advance works contract carried out to install the Bennetsbridge Stream culvert and fencing and walling between the N78 and Fortbarrington Road.

Other enabling contracts to facilitate the main construction works include:

  • rail removal contract
  • advance fencing contract
  • diversion of a 315mm diameter gas main
  • diversion of the 110kV overhead high voltage ESB powerline

The main construction contract was procured under a restricted procedure, with award based on 80% price and 20% quality criteria. Tenders were received from six contractors in May 2021, and, following the tender assessment process, the letter of acceptance was issued to BAM Civil Ltd. in October 2021.

ROD-AECOM is currently providing the Employer’s Representative and a team of site-based supervision personnel to undertake the administration of the contract through the construction and handover stages.

  • Multidisciplinary ecological surveys
  • Screening for Appropriate Assessment
  • Stage 2 Appropriate Assessment (Natura Impact Statement)
  • All assessments for, and the preparation of, the Environmental Impact Statement (EIS)
  • Advance contracts, including topographical survey and geotechnical investigation
