1. The present tender texts are a sample bill of quantities and make no pretentions to completeness

2. Use of these text modules does not release planers/users from the responsibility of checking the specifi c local features at the construction site and other regulations existing for fi re safety, etc.

3. Applicable technical and legal construction regulations must also be observed.

4. When the product is not specifi ed specifi cally, it shall be assumed that the system tendered is offered.

5. If materials other than those listed in the bill of quantities are used, it is legally obligatory to verify their equality with the materials described in the tender by means of analysis values (test reports from offi cially recognized testing institutes or equivalent verifi cations).

6. Before performing the described work, all required connections (such as pipe passages, windows, exterior doors, window sills; electrical installations, etc.) must be completed.

7. The subsurface must be dry, supporting and free of grease or oil; it must be ensured that the roof or wall has not been penetrated by moisture from the outside (e.g. driving rain).
