Examples of Proposal Request Aids

In order that specification sheets for the rehabilitation of sewers can be laid down in a professional and safe manner and that they contain all the information to enable the tenderer to work out a price and to execute the work, aids to proposal requests have been developed by various institutions in the past years, such as:

• ATV-M 143 Part 5 (Abschnitt 5.6.3.2.4.1) : "Allgemeine Anforderungen an Leistungsverzeichnisse für Reliningverfahren" (General requirements of specification sheets for relining processes) [ATVM143-5a] ;
• AGI (Abschnitt 5.6.3.2.4.2) : "Kanalinstandhaltungs-, -sanierungsarbeiten - Leitfaden für Leistungsverzeichnisse" (Maintenance-, rehabilitation work - guidelines for specification sheets) [AGI94a] ;
• Standardleistungsverzeichnis (Standard specification sheet) (Abschnitt 5.6.3.2.4.3) [GAEB] with Leistungsbuch LB 309 (Specification book LB 309) (Abschnitt 5.6.3.2.4.4) [LB309] as well as LB 310 [LB310].
