Construction was completed in October 2018, now start work on the arrangement of business and public areas.

Facade Cleaning System
A unique system of hoisting mechanisms is tailor-made for Lakhta Center Tower to maintain (clean and current repair) of glazed facades which will successfully operate on the building of a twisted and convex shape.
Building maintenance unit is designed separately for each “leaf”.
A smart snow removal system is designed, PETD impulse method will be applied.
The total area of the facades is over 130,000 sq.m. of glass which should be maintained clean and the elements of the structures should be repaired, if necessary.
Up to elevation of 369m a Building Maintenance Unit operates comprising carriages, a platform, rails along the arris of the building. Rubber rollers prevent from damaging the façade.
The entire system ascends from the ground level. Two people can be on one platform. There are three safety steps, i.e. the main rope, a backup rope, a lock system.
The top of the pinnacle will be maintained by industrial climbers. They use electric traction hoists.
North and South Blocks of the Complex have fairly complicated inclined facades. To maintain them the following will be involved: two portable cranes with boom outreach 4.37m, six cranes with boom outreach over ten meters, the atrium inside other two cranes with boom outreach 12,5m.
To maintain the arch facades skylifts will be used with a maximum operating boom outreach 18m.
Cradle fixation points will be provided throughout the façade with a negative gradient. A cradle can be fixed and heaved alongside the façade as it goes up or down.
An overall time of glass cleaning in the tower is 94 days. The crew comprises 20 workers.
The cleaning of the facades of two blocks takes 119 days outside and 104 days inside. The crew comprises 20 workers.
