At Priedemann any project starts with the determination of the planning basis, with the facts, requirements and possibilities – no matter when we start and always together with everyone involved in the project
Priedemann develops the facade concept for planning ready for approval – taking into account all planning principles and requirements determined up to that point, e.g. the climate plan, building technology and building statics.
Priedemann sees the implementation planning as a precise simulation of the construction process and the building – in detail, digitally and, depending on the complexity, as a 3-dimensional model.
For tendering and awarding contracts Priedemann defines and specifies the planned facades and details as well as the connections to adjacent components.
Priedemann provides clients with comprehensive advice independent of individual manufacturers and systems when selecting the best award procedure and the most suitable manufacturer.
We know the market: Our experience from hundreds of projects with various manufacturers is incorporated into our consulting services.
The first phase after the award of the contract is of particular importance. Often some time has passed since planning and a number of changes may have occurred, the planning team has changed, user requests have been added or additional requirements are putting pressure on the budget. Priedemann checks and assesses whether all of the documents are up to date, complete, feasible and if any improvements can be made, coordinates change management and is the contact for all questions of the planning team concerning the facade.Before the work is planned
The supervision of assembly and installation is particularly important for us, to ensure the agreed quality. Our principle is that deviations from the agreed planning must be identified at an early stage, documented and the implementation corrected. This controlling refers both to production and manufacturing as well as to the assembly on the building site:Regular inspection of production and assembly in the factory
The aim of Priedemann’s thermal-structural planning is to minimise heat losses and undesirable heat input through the exterior of the building and to avoid damage caused by weather conditions. The range of services includes identifying all influences and values relevant for the facade structure as well as the exact dimensioning and determination of the materials for the layer structure of the facade.
Buildings, their functions and methods of construction and their technical systems are becoming increasingly complex. Standardised calculation methods are often no longer adequate to determine building physics values. Here Priedemann relies on various computer-based simulation tools. We feed our simulation programs with the planned overall concept consisting of building services, the building structure and the facades and climate data in order to determine the achievable comfort values according to ISO 7730 or the heating and cooling loads.
The absolute, relative (perceived) and maximum room air temperature or the maximum number of hours in which these values are exceeded are often the main factors.
To this end, particularly critical rooms in a building are identified and analysed so that recommendations can be made for further specific planning. When we need to analyze particularly complex systems or processes, we use a range of 3-dimensional flow simulations (CFD Computational Fluid Dynamics). For this purpose, we convert the given three-dimensional building structure into CFD-readable data sets and enter the energetic, building physics and weather data into the program. For example, statements on flow velocities, temperature distributions in the room air and on surfaces can be determined.
We also use CFD programs for the verification of smoke extraction scenarios as well as necessary or planned smoke extraction and post-flow cross-sections. Cross-sections or the number of conventionally determined smoke extraction openings can thus be optimised and often reduced.
Facades have to cleaned and maintained. What sounds trivial is a component of facade planning and maintenance, which ensures the long-term value of a project, so it should not be underestimated. Priedemann keeps operating costs low by making the logistics of maintenance and cleaning an integral part of the planning right from the start. This is not only about equipment for maintenance and cleaning, the type and design of the facade itself can make a decisive contribution. Facade solutions that do not take this into account during planning and construction make maintenance more expensive over the entire service life.
