Before starting the installation, it is necessary to check the works and analyze if
there are deviations in the existing works (structure alignment, dimensions, etc.)
that could concern your own works and stop you installing materials properly.

Your own works must be inspected regularly to verify that all the works are
being developed according with the manufacturer’s instructions and the
construction rules.

When defects in the alignment, etc. the contractor should correct the defects or
installing a substructure prior starting our works.
Maximum deflection of purlins must be considered to avoid water retentions on
the roof.
