The science block, which was first built in 1969, required earthquake strengthening and the school took the opportunity to modernise the facilities. Local firm W&W Construction completed the strengthening work and more than 90 per cent of the work had been done by other Wanganui contractors and subcontractors - BSM Group Architects, BPL Group Engineering, and Saunders Stevenson quantity surveyors and project managers.
Mr Moller said it reflected the school's policy of employing local business where possible and the work was funded by parent-paid attendance dues, which were part of the school's integration agreement and not part of the ministry grant.
The work started in December last year. The refurbished building now has "top-of-the-line" laboratory classrooms, a secure chemicals store room and an external dangerous-goods store.
