| The project comprised 144.32 tonnes of structural steelwork and 14.16 tonnes of purlins. |
| The beams and purlins provide the support for the upper level and are made of construction-grade wood, complete with knots and other blemishes. |
| Speaking through an interpreter Mr Candia described a wall moving after they pulled out timber purlins supporting a parapet wall. |
| Then they fastened an array of closely spaced purlins to the rafter beams, using traditional wooden pegs. |
| Horizontal tubular-steel purlins running over the arches in turn support vertically aligned tapered arms ending in stainless-steel fixings. |
