Our Projects

north-ringCork Northern Ring Road (Northern and Western Section) – Hydrology

Client: Cork County Council/Cork City Council

Location: Cork, Ireland

Capital Value: c. €175 M

Key Facts: The Cork Northern Ring Road project consisted of a northern and western section.  It included the production of Route Selection Report which considered various tunnel and viaduct bridge options over difficult and environmentally sensitive terrain.

On the western section, FT were responsible for the preparation of the Route Selection Report which included an examination of tunnelling and bridge options.  This included the River Lee crossing which will involve a landmark structure.

FT collaborated with the Lee Catchment Flood Risk and Management Study (LeeCFRAMS) team, including the Office of Public Works (IRE), which was ongoing at the early stages of the Contract.  The results of the LeeCFRAMS informed the design of the proposed bridges on the scheme.  The hydraulic river models were examined to provide an accurate interpretation for the road scheme.

Other FT responsibilites included:

  • Hydrological Impact Assessment for EIS
  • Input to cost benefit analysis
  • Input to the bill of quantities
  • Collaboration with our in-house geotechnical team on the results of the site investigation, for potential impacts on hydrology and drainage
  • Preliminary Design and Report
  • Bridge Feasibility Report and preliminary design for the:
    •  Glashaboy River crossing (approx 220m long with an estimated cost of €3 m)
    • River Lee (estimated cost of €15 M)
  • Input to cost estimate for the Works
  • Liaison with stakeholders, utility companies and statutory bodies.
  • Tunnel Feasibility Report with tunnel options of up to 1.5km in length at a depth of 80m

Drainage Impact Assessment

Galway-Wind-ParkGalway Wind Park – Hydrology Assessment

Client: SSE Renewables (Ireland) Ltd.

Location: Ireland

Capital Value: c. €2.0 million

Key Facts: Galway Wind Park comprises four separately consented wind farms, for which FT were responsible for the preparation the EIS and planning application of three of these permitted sites.

FT was responsible for consultation with interested parties, extensive ecological surveys and reporting, soils, geology, hydrogeology and peat stability assessments and water quality and hydrological assessments.

FT also prepared an additional planning application (and accompanying EIS) for the turbine delivery route for Galway Wind Park, which involved some works to widen the N59 Junction, to remove some pinch points and for the installation of passing bays along the local/forest road from the N59 to the site.

In preparing the preliminary drainage design and the turbine delivery route for these wind farms, FT’s responsibility was to ensure that the designs would avoid any adverse impact on the hydrological regime and water quality in the nearby receiving waters and lakes.

Governorate-of-JeddahSurface Water Assessment for Governorate of Jeddah, Kingdom of Saudi Arabia

Client: AECOM

Location: Jeddah, Kingdom of Saudi Arabia

Capital Value: N/A

Key Facts: The JEA comprised 15 Data Assessment (including surface water) and Analysis Reports, each of which addressed key areas of concern regarding the human and natural environment in Jeddah.

The overall objective of this assessment being the evaluation of the current state of surface water in Jeddah; the identification of sources of contamination that had the greatest influence on surface water quality, and the development of achievable and measurable improvement measures that will advance Jeddah from its current state to that of its vision to be a “world class sustainable city”.

As part of its remit on this project FT:

  • Undertook a desk based assessment and site walk over, to assess available data on rainfall patterns, historical flooding, to examine the locations and existing state of surface water infrastructure, to observe hot spots (evidence of pollution) and identified impacts and risks on surface water quality in the region
  • Potable water sampling was undertaken and interpreted with recommendations at 25 locations across the study area
  • Prepared an assessment and analysis report for surface water, which fed into a Summary State of the Environment Report for Jeddah
  • Identified the potential policy and regulatory options to improve surface water quality in Jeddah for sustainability of ecosystems and enhancing the amenity value of existing surface water infrastructure
  • Undertook a cost/benefit assessment of the options identified, with the aim of prioritising improvement measures.
