Spencer Dock

This urban regeneration project by Spencer Dock Development Company Limited involved substantial demolition and site clearance at the former C.I.E. terminal building and Campshire sites on North Wall Quay. Extensive basement excavations were carried out to service both the new Price Waterhouse Headquarters block and the National Convention Centre. This involved the management, excavation and removal of 150,000 cubic metres of materials including disposal of a large volume of hazardous material to licensed facilities in Ireland and abroad. An extensive pumping and dewatering system was set up for both basements which extended to 14m deep in this tidal site.

As part of the overall site development, a section of the Royal Canal bounding the site was remediated and realigned. This involved damming, clearing, constructing of various bunding configurations for flow management, over-pumping, installation of settlement tanks and the removal of all silt and accumulated fill from this section of the canal. These materials were heavily contaminated and were subject to rigorous examination and categorizing before disposal at relevant disposal outlets, again in Ireland and on the continent. Included in this diverse package of works was extensive civil engineering and infrastructure works in the complete development of this 50 acre plus city centre site involving:

  • Modification and addition to existing utilities on the busy port roads surrounding the site, involving road openings, traffic management and liaising with all the Local and Civic Authorities.
  • Installation and testing of 3.50 km of various watermains and associated fittings.
  • Installation of 25km of service ducts for new utilities.
  • Construction of 7,000m2 of site road network including all preparations.
  • Provision and placing of 4,000m2 of natural stone paving along with 1,200m of kerbing to include preparation and protection.
  • Installation of 2km of surface water drainage along with outfall manholes into theLiffey. A similar amount of foul drainage was installed along with connections tomain drainage systems on New Wapping Street. These works were carried out in conjunction with officials from Dublin City Council.
  • We also worked closely with other contractors in forming a path for new Luas line, involving sweeping the line path for services/containments and the construction of service ducts, bases, sub-base and the like for the new railway line.

These extensive works, valued in excess of €25M, were carried out in complete harmony and in an unbroken programme of 5 years under the main contractors – CMP.
