  1. Reinforcement and formwork shall comply with relevant clauses of Specifications 822 STEEL REINFORCEMENT and 821 FORMWORK respectively.

829.07TOLERANCES
  1. The precast panels shall be manufactured to the dimensions shown on the Drawings within the following tolerances:

  1. Overall dimensions of length and width and height ±3mm.

  1. Cross-sectional dimensions ±3mm.

  1. Deviations from a straight line shall be no more than 3mm on a 2m template.

829.08TEST PANEL
  1. The Contractor shall produce a test panel to the dimensions and finish of any one of the panels shown on the Drawings.

  1. Prior to the commencement of production of panels for incorporation in the Works, the Contractor shall present the test panel for the Superintendent’s inspection.
/ HOLD POINT
829.09HANDLING AND STACKING
  1. The Contractor shall be responsible for all handling and stacking of the precast panels and shall ensure that no panel is removed from a mould until the concrete has gained sufficient strength to safely withstand handling stresses.

  1. During handling and stacking operations the panels shall be supported only at the points detailed on the Drawings and the Contractor shall take due care to protect the surface of the panels from deterioration.

  1. Any units damaged or distorted in excess of the specified tolerances prior to or during installation shall be replaced at no cost to the Principal.

829.10ACCEPTANCE
  1. Panels shall be rejected if they exhibit spalling or cracking, including hairline cracks, or staining or any substantial variation from the texture and colour of the test panel.

INSTALLATION
829.21INSTALLATION OF PARAPET PANELS
  1. Panels shall be fixed to the line and levels as indicated on the Drawings with the following tolerances.

  1. Change of alignment3mm/3m max

  1. Overall out of alignment10mm max

  1. Out of alignment on adjacent panels3mm max

  1. The finished line of the panels shall present a smooth and regular appearance.
