Construction activities (construction-installation or demolition work performed with the aim of the construction, remodeling, expansion, renovation, rehabilitation, improvement, maintenance, repair, demolition or relocation of a structure, a section of a structure or group of buildings) may only be performed with a final and executable building permit, with the exceptions listed in Annex 1 to Government Decree No. 312/2012 (XI. 8.) on the construction and building inspection authority procedures and checks as well as administrative building services.
A building permit shall be obtained for the whole construction activity performed on one plot (land area registered under one property lot number) in a given period.
An administration shall be involved in the building permit procedure if required by Annex 6 of Government decree 312/2012 (XI. 8.) on the construction and building inspection authority procedures and checks as well as administrative building services.
Developer may request a preliminary opinion from the competent administration before applying for a building permit.
In case of construction work performed on one plot in several phases, a building permit may either be obtained for all phases at the same time – by indicating the specific phases – or for the specific phases separately, while describing the whole construction project.
Applications may be submitted electronically, through the ETDR electronic documentation system that supports the permit procedure of the construction authority, or in a hard copy.
Tender plans are typically devised for large-scale projects, where the construction plans take long to draw up, and the developer wants to start preparation for the construction before those plans are completed. The tender plan includes a not fully detailed construction plan documentation based on the building permit plans, and a Bill of Quantities by the designer, which is a part of the construction plan. Typically it is less detailed in respect of junctions and detailed plans.
The tender plan provides the developer with a good approximation of the costs of the building with the current technical quantities, which significantly helps with the financial predictability and potential pitfalls of the project.
Once the building permit plans have been approved, architectural and specialist designers work together to create a sufficiently detailed plan, the construction plan, based on which the building can be built, unambiguously and in high quality.
Materials are specified here and this plan contains detailed calculations. It gives clear instructions to every participant of the construction process as to what, how much and how should be built in and used. Based on the construction plan, the appropriate general contractor can be selected, and it can be used when the parties settle, as the developer knows what exactly contractors were required to do and how much material they can charge the developer for.
Without construction plans the general contractor, or the bricklayer or the joiner, etc. will decide the cover of the facade the type of thermal insulation or what windows to install. It is easy to see that the interests and priorities of constructors and developers are often different.
The cost of the construction plans will pay for itself many times over in the course of the construction. What shall be included in the construction plans, and when these plans shall be submitted are provided for by Government decree No. 191/2009 (IX. 15.) on building contractor activities.
Buildings constructed according to the permit drawings and construction drawings almost always diverge from the original architectural and specialty plans. As-built plans are drawn to indicate these modifications, according to the actual parameters of the building.
The essence of this is to record the information we, as designers, provided for the construction after the construction drawings were completed, and the discrepancies in the actually constructed building that exceed the tolerance.
By drawing the as-built plans we intend to record the parameters of the completed building so that information on the building is available in case of disputes, and for the observation, operation, maintenance, renovation, sale, remodeling or extension of the building, and for construction projects in its immediate environment.
The accuracy by which the costs of the planned project can be estimated depends on how detailed the plans are. If you track a project from the first drafts, it improves the planning security of finances and helps avoid surprises. The first cost estimate is calculated according to the size of the planned functions, and later, when technical quantities are more detailed, a more accurate budget can be devised with the specific geometry and the building materials assigned to the surfaces. Based on the construction plan, an itemised list is created including every element to be built in, also considering and calculating the necessary technology and time. This Bill of Quantities can be used in the call for proposals, while the Priced Bill of Quantities provide the most realistic calculations possible.
Operational plans contain information required for the effective operation of the completed building and the description of the modern technology and equipment that have been installed. In addition to the functional description of ventilation, heating, water treatment, shading, etc. systems, an interactive operation interface can also be created. For this, it is essential to have a set of plans that sort of closes the design process.
Accurate information on the measurements of the building, its cooling surfaces, the rooms to be illuminated, the operational lifts, etc. provide help in estimating future operational costs and adjusting operational parameters. In addition to all of the mobile and energy consuming equipment, the surfaces exposed to environmental effects and the number and activities of the people using the building are also essential for the accurate calculation of the annual cycle.
Plans created in BIM contain information on the whole life-cycle of the buildings. This set of information is different for every project. Our experience and continuous learning ensures that we use the optimal work processes to meet the clients’ needs, thus delivering a product that is cost-effective and yet professional.
As a dynamic engineering team, we are committed to innovative solutions and services. We believe that 3D representation is much more than mere visualisation. Assigning reasonable data and properties to the elements of 3D models provides a great advantage in all areas of construction projects. With the information models we create this way, time, energy and money can be saved in the course of construction, the preparation of the construction, and operation; all through to the demolition of the building.
As our group’s activities include both planning and implementing construction projects, our staff is much more experienced than firms that “only” offer BIM processing.
With our up-to-date office infrastructure and comprehensive knowledge of software programmes (ArchiCAD, Revit, AutoCAD, Tekla, AxisVM, Vico Office, Solibri) we can meet the needs of even the most demanding clients.
For every project, we consider the type and scale of the given task to assess what is needed for the project; once that has been established, we make a proposal about the necessary work processes to the client.
If we want the building information model (BIM) built by the engineers to be created with maximum efficiency, it is important to facilitate the undisturbed, effective and efficient cooperation of information. Accordingly, related consultancy is an essential service of TSPC BIM Kft. With this, we save time, energy and money for the client and for the designers.
Within this type of service, we deliver the following:
