Project Summary

St. Joseph’s National School is a long-established school in Dun Laoghaire, County Dublin, with the original school opening 1860.

To prepare for a rise in student enrolments, the client required modular classrooms that would be completed in time for students starting the new term. McAvoy was appointed due to an acknowledged reputation for delivering high-quality modular buildings within the education sector and being able to respond and deliver within tight timeframes.

FacilitySmartClass® modular classrooms

Building Size401 m2

LocationDunLaoghaire, Co. Dublin

Time on Site16 weeks

The offsite Solution

Four SmartClass® modular classrooms with WCs were delivered  to site with 80% of the works having already been completed at our 70,000 sq ft purpose-built manufacturing facility, this included, electrics, internal partitioning, flooring, cladding and features an Air Sourced Heat Pump in accordance with NZEB requirements. The project was completed within 16 weeks and was delivered on time and to budget.

Harnessing innovation

This project also included early adoption of BIM due to the short deadline which allowed the project to be seen and reviewed in its entirety, identifying any issues at the design stage, and providing the client with a solution.

Comprehensive site works

McAvoy also facilitated site works including landscaping around the building, footpaths, and a small car park area for ease of accessibility into the classrooms.

Project Challenges

With a tight programme and a challenging site area due to a tree lined avenue, alot of planning went into scheduling as well as tree surgery and collaboration with local residents to ensure minimal disruption to them.
