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.

North Shore Hospital

North Shore Hospital

North Shore Hospital Building 5 was constructed in the 1960’s for the purpose of being occupied as staff accommodation. The structure of the building consists of an inadequately filled concrete masonry reinforced exterior cladding with a hollow clay block used as formwork for the 70mm concrete floors. The 2nd story resides of a mix of internal concrete brace walls and structural timber holding the light weight roof. The new purpose of the building is to create a hospital outpatients ward on level zero and offices and teaching facilities on level one and two.

Brosnan Construction have worked on numerous projects resulting from the damage caused by the Christchurch earthquakes, however, this one was a bit special. Involving an historic building dating back to the early 1900’s, it was one of few commercial buildings on Lichfield Street to still be repairable.

Enabling commercial tenants to resume trading in the shortest possible timeframe is a challenge in itself when repairing earthquake damaged premises, but when further damage is only discovered during the project, then it can place strain on both timelines and budget. Dealing with these issues professionally is paramount to success.
