Part  B  -  Verifications  and  approval  requirements

•  In  the  case  of  concrete  components,  checking  the  following  after  production  and  prior  to
commissioning
-  The  age  of  the  concrete,  resp.  its  consistency  prior  to  subjecting  it  to  loads  (possibly  including ­
  a  hardening  test)
-  Surface
-  Cracks
-  Desiccation
-  Joints  (e.g.  construction  joints,  grouted  joints,  material  transitions)  and
-  Fixtures.
•  In  the  case  of  concrete  components,  inspection  of  the  following  after  production  and  prior
to  commissioning
-  Recorded  information  and  concrete  delivery  notes  and
-  Levelling  log.
•  In  the  case  of  precast  concrete  components,  a  respective  check  at  the  préfabrication
plant.
•  In  the  case  of  precast  concrete  components,  inspection  of  the
-  Labelling  and  delivery  notes
-  Monitoring  reports  of  the  recognised  monitoring  body
-  Certificate  of  compliance  and
-  Verifications  with  respect  to  special  manufacturing  processes  (e.g.  spun  concrete).
•  When  installing  precast  concrete  components,  checking  the
-  Lifting  anchors
-  Limiting  dimensions  (components  and  connectors)
-  Storage  and
-  Possible  transport  and  installation  damage.
•  When  installing  precast  concrete  components,  inspection  of  the  installation  instructions.

2.4.2.1.4  Monitoring  of  the  production  phase  (grouting)
With  respect  to  grouting,  the  requirements  set  down  in  the  individual  Technical  Approval  (Appendix ­
  2)  shall  be  observed.  The  on-site  monitoring  measures  for  a  construction  site  classified
as  a  monitoring  class  3  site  in  accordance  with  DIN  1045-3,  as  well  as  any  other  additional
monitoring  measures  required  as  a  result  of  the  individual  Technical  Approval,  shall  be  carried
out,  resp.  commissioned,  by  the  contractor.  The  specialist  assessment  shall  be  conducted  by
the  assessor  engaged  by  the  approval  holder.  The  results  of  one's  own  and  any  third  party
monitoring  measures  shall  be  submitted  to  the  appointed  inspector.

2.4.2.1.5  Monitoring  of  the  production  phase  (cast  components  of  the  support  structure)
The  cast  components  to  be  monitored  include  all  cast  components  that  have  an  impact  on
the  stability  of  the  installation  (e.  g.  cast  nodes).
With  respect  to  cast  components,  the  following  documents  shall  be  submitted  to  the  appointed ­
  inspector:
•  Component  specifications
•  Drawing  of  the  raw  casting
