Monitoring of site investigation trenches was undertaken at the site of the Dublin Waste to Energy Project, Poolbeg, Dublin 4 between September and December 2014. Monitoring of ground works and site investigations was recommended in an EIS undertaken for the project in 2006. Site investigations were conducted over two phases in the area of the Dublin to Waste development site. In total 23 test trenches were excavated, ten in Phase 1, 13 in Phase 2. The majority of the trenches encountered significant modern fill deposits associated with estuarine land reclamation south of the modern Pigeonhouse Road. Test trenches excavated as part of Phase 2 (Test trenches 12 and 13) exhibited the partially truncated remains of a metalled surface and walling. These remains are considered to have formed part of the causeway which led to the 19th-century Pigeonhouse Fort. Both test trenches were only excavated to a depth where extant services could be identified. The archaeological remains exposed were covered with a protective layer of sand before backfilling.
The site of a coffer dam associated with a pump station for the facility was excavated during October 2015. Significant reclamation deposits overlay navigation channel silts with modern debris inclusions. Nothing of archaeological significance was recovered.
