2.2 Protective and safety scaffolding, as well as any scaffolding required on and in roofs for e.g. bay windows, chimneys, backs of gables, will always be listed separately and invoiced separately in accordance with VOB/C.

3. obligations of the Client / use of scaffolding

3.1 Scaffolds may only be used for the purposes specified in the offer or order. Structural changes to the material, to the anchors or the attachment of safety nets etc. may only be carried out by the employees of Mack Gerüstbau GmbH. The customer takes the scaffolding into his care during the holding period and is responsible for careful handling, maintenance and proper use of the scaffolding.

3.2 Permits for the special use of public land as well as third-party land and buildings must be obtained by the client before the scaffolding is erected. Possible fees shall be borne by the client. If a registration or the permission of an official body or the consent of a neighbouring landowner is required for the erection of the scaffold, the client shall ensure that these requirements are duly met before the start of assembly.

3.3 The client undertakes to acknowledge the reports drawn up by us, e.g. on the number of anchors, number of ladder accesses, etc. If the number and condition of the anchors and the scaffolding deviate from the acknowledged condition, the client shall be liable for the consequences thereof and shall release us from any liability.
