As part of the Department of Education’s enhanced modular buildings programme, Actavo Modular was selected to provide a state-of-the-art two-storey building to Hollywoodrath School in Hollystown, Dublin 15, covering 4,223sqm. The project was completed in only 14 months.

Scope of works
Actavo Modular created a bespoke design to meet the school’s requirements. It comprises of 24 classrooms, a two-classroom special education needs unit and external facilities. Material quantities included:

• 150mm concrete composite floor (cast off site in manufacturing facility in Kill and transported and installed on site).
• 750m2 of brick slip
• 375m2 of render
• 1,200m2 of curtain walling
• 4,850m2 of external paving
• 4,500m2 of roadways and car park area
• 20,000m3 of reduced level dig
• 1,400m3 of raft slab

Services delivered
• A comprehensive turnkey service that includes design, fabrication, installation and delivery of 152 steel framed modular sections, comprising 4,223sqm in total and incorporating a feature staircase. The heaviest module weighed over 36 tons.

• All civils works were carried out, including external hard and soft play areas, two ballcourts, car parking and bus set down areas.

Key successes
• As the largest enhanced modular buildings project in Ireland to date, this project marks a pivotal moment in the modular construction industry.
• Combination of permanent and modular building solutions with the use of concrete flooring.
• High safety compliance on site with zero LTIs for the full duration of the project.

Community engagement
Throughout the duration of the project, we remained consistently attentive to the needs and concerns of the surrounding community. There was proactive engagement with the Neighborhood Watch group and a system was established to promptly address any concerns. Controlling noise pollution was prioritised to ensure minimal disruption to local residents.

Solutions to challenges
• Bringing in 152 modules without disrupting traffic or surrounding neighbourhoods was a challenge. Actavo Modular worked in conjunction with our transport partners and neighbouring communities to safely deliver the 4m wide modules.
• Challenging ground conditions on site required extensive civils works to be completed prior to module delivery to site.
• Significant planning and care went into the logistics of lifting such extreme loads in the manufacturing facility and their installation on site. Complex lifting plans were put in place to assess the weight of each individual module and to strategically place temporary supports and lifting points to each module. This ensured modules ascended and descended vertically and level into position.

Benefits to client
• In excess of 80% of the building fit-out was completed in our factory pre-delivery, saving the client time and money.
• The building’s standard 60 year structural warranty will serve the local community for generations.
• Using innovative materials, the school is designed to achieve optimum energy efficiency, flexible interconnectivity and structural integrity.
