Project Overview

1-6 Sir John Rogerson’s Quay (1SJRQ) is a mixed-use development comprised of two retail units and 10,487m² of office space arranged over six floors with a 24-metre-high sculptural atrium above the entrance lobby. The building overlooks the River Liffey with a subterranean carpark, lockers and shower facilities. No.’s 2 and 4&5 Sir John Rogerson’s Quay are areas of conservation within the project. No. 2 SJRQ is the remnants of an old tram depot which retains a redbrick façade, creating a dramatic entrance to the property from the main street. This leads into a landscaped courtyard before entering the six-storey atrium of the new building. No.’s 4&5 SJRQ were previously Georgian houses that have now been renovated into office spaces on the upper floors and connecting into the new main building. The ground floor of No.’s 4&5, a café / bar, opens into a three-story glazed atrium courtyard to the rear of the buildings. This atrium separates No.’s 4&5 from the office units of the new development. The riverfront elevation to the new building, including a curved portion, is clad with a full-height floor to ceiling frameless glazing system which also includes external, vertically spanning glass fins. The building has an overall floor area of 15,000 m² and is constructed to a LEED platinum standard.

The project involved extensive and complex elements of temporary works design and coordination. Due to the confined nature of the site, innovative solutions were developed to reduce impact to our neighbours and traffic movements local to the project.

The implementation of BIM on this project benefited all aspects of the project delivery. A primary example of this was the installation of the three catwalk bridges which span 14 metres across the main atrium space and weigh approximately 20 tonnes each. One of the main challenges faced on site for this item of works was determining a safe and controlled method to install the bridges. We carried out a detailed analysis of this method, in collaboration with our in-house BIM team, and using Fuzor software we simulated the operation in full. This facilitated the detailed communication of the sequence to the installation team, ensuring that all bridge sections were installed in one eight-hour shift. The engagement of our BIM capabilities through a collaborative approach to complete this phase of the works was key to the successful implementation and completion of these works on site.
