Major transformation
The complete Tatneft Tower modernisation appointment, undertaken as a subcontractor.

OSAN / DISCIPLINE 05
New possibilities within an existing building.
What the discipline brings together
Existing buildings can demand change at very different scales. OSAN’s references range from the complete major modernisation of Tatneft Tower to interior refurbishment and landscape work at Lotte Hotel Moscow.
Modernisation begins with an existing architectural condition. The extent of intervention may concern the whole transformation or a particular part of the building; the appointed scope defines OSAN’s responsibility.
ENGINEERING IN FOCUS
Modernisation connects an existing condition with a proposed architectural expression. Understanding what is retained and what changes establishes the logic of the intervention, from the building’s overall form to the places where old and new meet.

New envelopes, revised spaces and altered circulation create relationships with retained construction. These meeting points require the transformation to be read as a connected whole, preserving clarity between the original building and the work introduced by the renewal.
Renewal is a staged construction process. The order of removal, adaptation and new work influences how the project can be organised. The extent of the appointment determines whether the work concerns a complete modernisation or a particular part of a building.

From brief to delivery
Identify the intended use, work boundaries, design responsibilities, programme and relationships with adjacent packages. A clearly framed brief provides the starting point for engineering and construction decisions.
Consider architecture, engineering, procurement, mechanical and electrical works and construction together where they form part of the appointment. Resolve the relationship between the visible finish and the work supporting it.
Translate the agreed scope into a sequence of site activities. The building, its interfaces and its finishes call for different levels of coordination throughout the work.
Bring the appointed work to its intended handover. The relevant scope, programme and contractual requirements determine what is delivered and which records accompany it.
References demonstrate the specific packages described on their project pages; they do not imply a complete turnkey appointment.
