The method comprises maintaining, in a building information database (40) of a building information server system (44), a building information model of the building space (2), receiving, in an external maintenance service (50), a maintenance request from a client (20, 60), associating, by the building information server system (44), the maintenance request with the building information model of the Building space (2), and enabling access, by the external maintenance service (50), to the building information model of the building space (2) as response to receiving the maintenance request from the client (20, 60) for providing the physical and functional characteristics of the building space (2) to the external maintenance service (50).

Description

Method for maintenance work and maintenance system
FIELD OF THE INVENTION
The present invention relates to a method for maintenance work of a building space of a building, and more particularly to a method according to the 5 preamble of claim 1. The present invention further relates to a maintenance system for maintenance work of a building space, and more particularly to a maintenance system according to the preamble of claim 15.
BACKGROUND OF THE INVENTION
Buildings comprise usually one or more separate building spaces, such as apartments, offices or the like, which need maintenance work from time to time. The maintenance work may comprise renovation work, such as pluming, electricity, air conditioning, heating or structural renovation work. The maintenance work may also comprise changing, cleaning or repairing surfaces, 15 structures or equipment of the building space, such as window washing, sweeping or cleaning of air conduits or the like. Conventionally, the owner or occupant of the building space calls to a service provider who comes to the building space for inspecting the physical and functional characteristics of the building space for evaluating the maintenance work needed and the technical characteristics of the 20 maintenance work.
One of the problems associated with the prior art is that inspecting the physical and functional characteristics of the building space is time consuming and difficult task to be performed by the service provider. Accordingly, the service provider has to rely on manual inspection or measurements of the physical and 25 functional characteristics of the building space. The manual inspection may also be difficult as certain physical and functional characteristics of the building space cannot be inspected manually without breaking structures, such as pluming. Therefore, also technical drawings, comprising physical and functional characteristics of the building space, may be used to evaluate the needed 30 maintenance work. However, often the technical drawings are created when the building is built and they are not updated later when maintenance work or renovation has been carried out in the building or in the building space. Therefore, the service provider seldom can rely on the technical drawings.

BRIEF DESCRIPTION OF THE INVENTION
An object of the present invention is to provide a method and maintenance system for maintenance work of a building space of a building so as to solve or at least alleviate the prior art disadvantages.
The objects of the invention are achieved by a method which is characterized by what is stated in independent claim 1. The objects of the invention are further achieved by a maintenance system which is characterized by what is stated in independent claim 15.
The preferred embodiments of the invention are disclosed in the 10 dependent claims.
The invention is based on the idea of providing a method for maintenance work of a building space of a building or in association of maintenance work of a building space. The method comprises maintaining, in a building information database of a building information server system, a building 15 information model of the building space, receiving, in an external maintenance service, a maintenance request from a client the maintenance request with the building information model of the building space, and enabling access, by the external maintenance service, to the building information model of the building space as response to receiving the maintenance request from the client for 20 providing the physical and functional characteristics of the building space to the external maintenance service.
The method may comprise associating, by the building information server system, the maintenance request with the building information model of the building space, and enabling access, by the external maintenance service, to the 25 building information model of the building space as a response to receiving the maintenance request from the client for providing the physical and functional characteristics of the building space to the external maintenance service.
The building information model of the building space is a commonly known and utilized technical model of the building or the building space. The 30 building information model defines and comprises physical and functional characteristics of the building space. By definition, building Information model (BIM) is a digital representation of physical and functional characteristics of a building. A BIM is knowledge resource for information about the building. A BIM reaches 3D representation of the building, augmenting the three primary spatial 35 dimensions (width, height and depth) with time as the fourth dimension (4D) and cost as the fifth (5D). BIM therefore covers more than just geometry. It may also
20185696 prh 24-08- 2018 cover spatial relationships, light analysis, geographic information, and quantities and properties of building components and structures.
The maintenance request may comprise maintenance characteristics of the maintenance work of the building space. The maintenance characteristics may 5 comprise or may be directed to any physical and functional characteristics of the building space, such as structures, electricity system, pipings, devices, components or the like of the building space.
