Overview

Constructed in 1998, Block LM comprises the library and music teaching facilities at Wellington High School.

The library portion is a single storey building with a basement to a portion of the floor plate. Seismic resistance is provided by a mixture of timber framed walls, reinforced concrete block masonry walls and concrete frames. Precast nibs and infill flooring is present over the basement area.

The music portion is a two storey building. Seismic resistance is provided by a mixture of timber framed walls, reinforced concrete block masonry walls and concrete frames. The suspended floor is formed by precast concrete hollow core planks.

A detailed seismic assessment (DSA) on Block LM determined the following structural weaknesses –

Library:
• Seating of precast rib and infill flooring as well as seating of precast shell beam elements

To address the aforementioned it is proposed to:

• Install structural steel seating angles to precast floor elements

Music:
• Install structural steel seating angles to precast floor elements
• Install structural steel frame to support the western end of the precast elements
