What We Do

The Sails Building

Brosnan Construction was engaged as the main contractor to complete the structural repair for this project, a commercial building damaged in the earthquake of February 2011. The scope included the replacement of the façade system, the removal and replacement of precast wall panels, foundation upgrades, in-ground infrastructure replacement, car park formation, passive and active fire protection upgrades and interior fit-out works.

The building was occupied by 14 commercial tenants, all of whom had a vested interest in the project, which therefore demanded the highest levels of communication and consultation in order to understand and manage expectations as the works progressed.

The initial building levelling was completed by Uretek to raise the building up by 115mm to provide a level ground floor slab. This involved core drilling holes through the foundation so that grout jets could be installed. The building was then lifted by injecting specialist grouts through each grouting jet while fully monitoring the building levels using highly sensitive surveying equipment.

The demolition process included the disconnection of specific façade panels and removal without affecting the surrounding structure, which involved nibbling the panels away using a large excavator rather than cutting and removing them. This approach reduced the health and safety risks and potential associated structure damage to minimal levels.

Once the precast panel crack repair was completed using a high pressure injection system, the full Linea Weather Board façade was replaced. Interior upgrades and repairs were then undertaken, including fire protection and emergency lighting upgrades, ceilings, wall and floor coverings and interior painting works.

NZMA Carbine Road, Mt Wellington - Stage 1 & 2

Starting with a large, empty warehouse, the need to convert it to a state-of-the-art hospitality training facility and a very tight timeline placed the Brosnan team under significant pressure to deliver. The fact the finished product also went on to win an Award is just one indication of the successful outcome of the project.
