Education Sector Development

Mackin was contracted to deliver the groundwork services including drainage, foundations and hard landscaping. The work was carried out on a 13,000m site which was an existing playing field

Education sector groundwork construction project


  • 4,000 tonnes of material was excavated from the site.
  • A 27,000 litre rainwater harvesting tank was installed.
  • Half a kilometre of below ground drainage was installed.
  • A 600m concrete slab (with 52 tonnes of steel reinforcement) was poured.
  • To improve drainage, Mackin to install a permeable paving solution for the car park and playground areas.


  • Maintaining site safety at all times.
  • The rainwater harvesting tank was installed after the building was constructed. The challenge was to avoid undermining the foundations. A temporary ground support solution was developed which involved using a ‘vibrational drive before you dig’ technique.
  • Working adjacent to a ‘live’ school meant delivery times were restricted during ‘school run’ hours.


The project was delivered on time and Mackin continues to work with Ashe on similar projects.
