As a result of particular impacts and stresses affecting reinforced concrete cooling towers and chimneys and strengthend by their special structures and conditions of operation, adequate instructions are required for contractors initially applying or renewing surface protection systems. This Guideline therefore takes the form of additional technical stipulations to supplement the existing standards and codes. In this spirit, the Guideline is intended to assist the customer as an aid to decision-making and a basis for inviting tenders, placing orders and performing work of this kind. The customer in this context may be the owner and/or operator or a company employed by these.
Other applicable VGB publications on newly constructed cooling towers and chimneys include the Guidelines “Structural Design of Cooling Towers” (VGB-R 610)  and “Planning of Cooling Towers” (VGB-R 135)  as well as the Instruction Sheets “Industrial Chimneys – Evaluation of Designs, Notes on Construction and Commissioning” (VGB-M 642)  and “Chimneys for Operation without Flue Gas Reheating after FGD” (VGB-M 643) .
This Guideline is of particular importance in conjunction with the VGB Guideline “Code of Practice for Lifecycle Management of Reinforced Cooling Towers in Power Plants” (VGB-R 613 e) , the practical transposition of which is intended to ensure the usability of cooling towers throughout their service lives, preserving the function of surface protection systems. Recommendations for chimneys can be found in the VGB brochure “Zustandsüberwachung von Schornsteinen” (Condition Monitoring on Chimneys) (VGB-B 602) .
