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 in 
cluding 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 (Ap 
pendix 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 ap 
pointed inspector: 
• Component specifications 
• Drawing of the raw casting
