Description
Auto-translated from fiKOy Domus Arctopolis has assigned the construction unit of the technical department of the City of Pori the construction management task for the renovation to be carried out at Liisankatu 20, Pori. The project will be implemented as a divided contract.
We request offers for the construction contract (including demolition work), the plumbing contract, the ventilation and control system contract, and the electrical contract. The construction contractor will act as the main contractor and principal implementer of the project. The plumbing contract, ventilation and control system contract, and electrical contract are sub-contracts subordinate to the construction contract. The contracts will be executed as lump-sum contracts.
Bidders must carefully review the requirements set out in the request for proposals, as the renovation object is a building of significant architectural history. The renovation of the property in question requires considerable prior experience in similar demanding renovation work.
The project involves the renovation of Liisankatu 20 in Pori city centre, within a building complex protected by the town plan and regional plan. The site consists of a former school building (the "old part") designed by architect Yrjö Sadeniemi, completed in 1902, and an extension (the "new part") completed in 1990, along with its yard areas. The building will be renovated for use by the adult education centre and restaurant operations.
The aim of the renovation is to create healthy, safe, accessible, and modern premises while preserving and respecting the building's historical and urban landscape values. The building is protected (sr II), and the renovation work will be carried out in cooperation with heritage authorities.
Key measures in the project include the restoration and return of interior surfaces to their original appearance, replacement of intermediate floor insulation and acoustic improvement, space modifications, renewal of building services systems, improvement of accessibility (e.g., elevators, elevator shaft modifications, and accessible toilets), restoration and partial replacement of facades and windows, repair and renewal of roofing and upper floors, foundation and drainage work, and the restoration and renewal of yard areas and external structures. Material and structural solutions will comply with building preservation requirements and the indoor climate class S2 and cleanliness management class P1.
The project will be implemented as a divided contract, with separate tenders for the following contracts: construction and demolition contract, plumbing contract, ventilation and control system contract, and electrical contract.
The building's scope is approximately 3,757 gross m², with a total area of approximately 4,356 m². The content of each contract will be specified in more detail in the tender and design documents.
