High altitude works

A large number of high-rise constructions are currently being used all over the world.

They include:

• industrial chimneys;
• radio and TV towers;
• mobile communication towers;
• power transmission towers;
• lighthouses;
• bridges, crossovers, viaducts etc;
• residential, administrative and industrial buildings;
• other high-rise constructions.

Being particularly exposed to deterioration, high-rise constructions require special attention. Various factors such as atmospheric precipitation, seasonal and daily temperature oscillations, wind pressure, chemical influences etc. have an impact on the condition of high-rise constructions.

Practice demonstrates that the condition of high-rise constructions requires recurrent monitoring.

Monitoring should extend to:

• condition of material the high-rise construction is built from (concrete, bricks, metal shape etc);
• condition of metalwork (the ratio of corroded metal to non-corroded metal, the condition of fastening elements, the condition of anticorrosive coating);
• condition of electric equipment on the high-rise construction (signal lights, lightning protection, electric light fitting);
• verticality deviation;
• condition of support structures (foundation elements etc.).
