Sisk has been appointed as the main contractor for the Office of Public Works’ (OPW) new 14-storey landmark office building at Opera Square in the heart of Limerick city.

The project marks a significant milestone in the wider Limerick Twenty Thirty (LTT) programme, which is transforming the city and region’s economic and urban landscape. Once complete, the building will stand as Limerick’s and the mid-west’s tallest, overlooking the Abbey river from Bank Place.

The OPW has engaged LTT to deliver the development, reflecting strong confidence in LTT’s proven track record, including recent delivery of the site-wide basement works and the One Opera Square building. Sisk will construct the building’s shell and core, including structure, façades, roof, and primary building services.

The 30-month construction programme will employ up to 300 people on site and will deliver 100,000 sq ft of high-quality office accommodation.

Designed to meet the Nearly Zero Energy Building (NZEB) standard, the development will operate entirely on renewable energy sources, supporting the state’s energy-efficiency and emissions-reduction goals.

Once operational, the building will serve as a major hub for government departments in the mid-west, consolidating up to 1,500 civil servants, 950 at any one time under a hybrid working model, into a modern, digitally enabled workspace. The project will also help reduce the number of buildings in the OPW’s portfolio while supporting the regeneration of Limerick’s city centre.

Leanne Broderick, Managing Director, Regional Building, Sisk, commented, “Having recently completed the One Opera Square building, we are looking forward to partnering with LTT again to deliver the OPW building. As we commence works on site, our local knowledge and collaborative approach will be central to delivering this project successfully.”

Local leaders welcomed the project’s progress. Príomh Chomhairleoir, Cllr Catherine Slattery, highlighted the positive impact on the city centre, noting that the development will bring renewed activity, investment, and footfall to Limerick. LTT Chair

Chair of Limerick Twenty Thirty James Collins emphasised the significance of delivering one of the most ambitious elements of the Opera Square masterplan and acknowledged the OPW’s confidence in LTT and its partners.
