to be butted up to the original brickwork.<br />

At the 1/F there was spalling to ceiling and beam to external wall. The beam adjacent the<br />

Main hall wall was very damp, The beam to the courtyard side was spalled with badly corroded<br />

steelwork. The beams and columns had splits consistent with corroded internal rein<strong>for</strong>cement.<br />

There was spalling to the s<strong>of</strong>fit <strong>of</strong> the slab next to external wall.<br />

Spalling is not confined to the beams and columns<br />

but was also present in the slabs.<br />
