33 This evidence was consistent with Mr Carney's opinion as to how this collapse could have been prevented.
34 The evidence demonstrated that the obvious risk of this wall collapsing materialised. Mr Taric, a bricklayer of some 50 years' experience, broke both arms and suffered injuries to his neck, back, ribs and legs, when the bricks fell upon him. He also damaged his teeth when his chin hit concrete as he fell. On his evidence, about 18 courses of bricks fell. The wall was comprised of a single skin of bricks, otherwise unsupported. It was intended to tie the wall to the inside wall when that was built. Unlike Mr Carney and Mr Moussalli, he could think of no other way to build the wall.
35 Mr Baxter was a bricklayer of some 30 years' experience. He was also working on the wall when it collapsed. He broke his heel when he fell. On the previous day, he had raised a concern with Mr Moussalli about the wall which had been built that day. It was not as high as the one which collapsed, but he and another bricklayer noticed the wall moving and suggested that the wall needed to be braced. As a result, that wall was given a timber support. It did not fall, even though it was a windier day. Mr Baxter explained that he did not raise a similar concern about the wall which collapsed the following day.
36 On his evidence, that day was not as windy as the previous one and while there was a slight breeze which might have contributed to the collapse, he did not believe that wind caused it. He described the wind as blowing towards him, in the direction in which the wall eventually fell and agreed that as the wall increased in height, the bricklayers were sheltered from the wind, and may not have noticed, if the wind increased in strength.
37 In Mr Baxter's opinion, the wall was built too quickly and too high, given that it contained a number of large holes for doors or windows, over which heavy concrete lintels had to be laid, to support the brickwork above. This view also accorded with that of Mr Carney. In his statement to the Inspector, Mr Baxter said he believed the wall was 16 to 17 courses when it fell. In re-examination, he counted the courses which could be seen in photographs taken by the Inspector shortly after the wall fell. In the corner where he was working, where bricks had fallen out of the wall, there were about 18 courses. In the corner at the other end of the wall, where bricks had not fallen, there were 22. Mr Baxter's evidence was that the wall was being laid course by course, by the bricklayers working together.
38 On his evidence, Mr Baxter had concerns about the stability of the wall, as it was being built. His evidence was that he was not told how high the wall was to be built, before the work began. He was building the corner of the wall, which provided some support for the wall as it was constructed. As the day progressed, he was told to build the wall higher and began having concerns as to its height, but he did not raise them with Mr Moussalli, or with anyone else. In cross examination, Mr Baxter explained why he had that concern. On his evidence, the wall was raised to an unusual height. He described having not completed building the wall, but laying bricks, an arm's length above his head.
39 In his evidence in chief, Mr Baxter said that if he had been in charge, he would have built the wall only to lintel height, before building the internal wall. This would have enabled the cavity wall to be tied and would have allowed the external bricks to dry a little, before the lintels were put in place. In his opinion, that would have improved the stability of the wall. That evidence was consistent with advice which Infinity later received from its engineers, Ashby Doble and with the view Mr Carney expressed.
40 In cross examination, Mr Baxter agreed, however, that it was not normal practise to build the two walls comprising a cavity wall at the same time, or to brace the external wall, while the internal wall was being built. That evidence has to be understood, however, in a context where the wall was being constructed in sections.
41 The first lower section of this wall had been built with both walls comprising the cavity wall having been erected and tied together, about two days earlier. The work being undertaken on the day of the collapse, was to build the second section, up to finish level. On Mr Baxter's evidence, he would have built the upper part of the wall in two sections, not one, so as to improve the stability of the wall, as it was being built. On his explanation, because of the length and height of the wall being quickly constructed by up to six bricklayers, with the necessity to use heavy lintels to support the upper bricks, the mortar was too wet to ensure the wall's stability, given the height to which it was then taken. The lintels had the tendency to push down on the wet wall, exacerbating instability, to which the wind could have contributed, resulting in the collapse. Had the wall been raised only to lintel height, both cavity walls could have been built with wall ties to that height and the mortar would then have had a chance to dry somewhat, before the lintels were put in place and the wall was taken higher.
42 The evidence was that there were two lintels in place, each some 3.2 metres long. On the evidence, it would have taken two or three men to lift the lintels into place, given their weight.
43 Mr Kamaledine was also working on the wall and sustained cuts and bruises to both legs and a bloody nose, when the wall collapsed. He had some 10 years' experience in bricklaying and labouring, but was not a qualified tradesman. He had his back to the wall when it fell and unlike Mr Baxter and Mr Carney, could not explain why the collapse had occurred. In his statement to the Inspector, he said that 14 to 16 courses had been laid, when the wall collapsed. He was taken to the photograph showing the corner where Mr Baxter was working and counted some 18 courses there. On his evidence, normally brickwork would only be built to eyelevel. That was because the bricks are laid against a line, which is moved up as each course is built, to ensure that the brickwork is laid straight. It is necessary for the bricklayers to be able to see the line, to lay the bricks straight. He agreed that for him, 17 to 18 courses would be at his eye level.
44 Photographs to which Mr Kamaledine was not taken, showed that the number of courses laid in the opposite corner, which had not fallen, was 22 courses of bricks. It follows that those bricks must have been laid above eye height, as was Mr Baxter's evidence, also increasing the risk that the wall was not laid straight. It follows that this too, might have contributed to the collapse of the wall.
45 The double brick wall built two days previously had been connected by wall ties. The single wall that was being constructed on 12 February was not tied or braced, when it collapsed. On Mr Kamaledine's evidence, bracing was only undertaken when it was windy and the day of the collapse was not a windy day. Like Mr Taric, he thought the approach adopted to the building of the wall was a normal one. On his evidence the height of the wall was known to the bricklayers. The height was usually marked and it was the corner man, one of whom on this day was Mr Baxter, who usually told the other bricklayers when the required height was reached. It was Mr Baxter's evidence, of course, that the height to which the bricklayers were working that day had not been advised to them. Rather, they were instructed to continue raising the wall, as the morning progressed.
46 Mr Moussalli himself, gave no evidence as to what his instructions were that day. There was no reason to doubt Mr Baxter's evidence. In many respects, it was supported by the evidence of other witnesses.
47 When the wall fell, Mr Kamaledine understood that they were only about one course away from completing the wall. It was intended that they would then break for lunch and that in the afternoon, they would return to lay the inside wall. The wall was not complete when it fell.
48 Mr Huber also fell from the wall, braking his patella. On his evidence, the wall fell because it was raised too quickly and the bricklayers were not conscious of the wind. His evidence was that about 18 to 21 courses had been laid.
49 Mr McLennan was a senior site supervisor employed by Infinity. He had been asked if he would take over as supervisor of this site, a short time before the collapse of the wall. On his evidence, he visited the site twice before the collapse, for half an hour to an hour and started working at the site on 16 February. On his evidence, when he visited the site on the second occasion, he had concerns both about the quality of some of the brickwork which had been laid and the approach being adopted on site to safety. In his view, brickwork was being laid too quickly. He saw heavy lintels put onto walls which were too green - that is not set enough to support their weight. He spoke to Mr Moussalli about the need to prop the lintels, to support their weight. He explained that without such support, the lintels put pressure on the walls, causing them to move out of a straight line, giving rise to a risk of collapse. Mr Moussalli did not dispute this evidence.
50 Mr Richardson's evidence was that he never saw Mr McLennan on the site. The only occasion when Mr McLennan called in, he did not leave his car, only dropping some supplies. Mr Richardson was, however, on leave for two weeks before 9 February. On that basis, it is plainly possible that Mr McLennan's evidence and that of Mr Richardson were not inconsistent.
51 What Mr McLennan said he observed and discussed with Mr Moussalli was plainly a serious safety issue. On his evidence, Mr McLennan also raised his concerns about those safety issues with a director of Infinity, Mr Theo Orfanos. Mr Orfanos did not have responsibility for this site. It was the responsibility of Mr Alan Yazbek, another director. On Mr McLennan's evidence, Mr Orfanos told him to speak to Mr Alan Yazbek about the matter, because he did not have time to deal with it. Mr McLennan could not remember whether or not he tried to contact Mr Alan Yazbek, but he did not speak to him, or to anyone else who Infinity had at the site, with responsibility for safety, or even Infinity's safety officer, Mr Carney. Mr McLennan did not return to the site before the wall collapsed on 12 February. Mr Orfanos denied that Mr McLennan had raised this matter with him at all.
