This waste to energy plant at Poolbeg in Dublin will be the largest within the Republic of Ireland. Once operational it will incinerate up to 600,000t of waste per year, generating enough electricity for up to 80,000 homes.
All corners on the building are rounded, while the building also curves and slopes upwards. This created many technical design and construction challenges, including complex steelwork geometry. Such a challenging shape would not have been possible without the use of BIM, according to all of the design and steelwork team members. PM Groups’ use of Revit and model management tool Navisworks and Severfield’s use of Tekla, allowed for a detailed co-ordinated fabrication model that did not clash with the extensive process and services models.
Detailed planning went into the erection sequence and logistics due to the site being so confined. Also, working at height to lift large steel elements into place was another challenge that was overcome due to the extensive design and construction coordination between PM Group and Severfield.
All of the project’s processes are housed within one large steel-framed structure that will minimise noise. It measures approximately 200m x 100m, rising to a maximum height of 52m (excluding the flue which will be 100m-tall) and is due to be fully operational in 2017.
