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
- What is the design concept?
- Which local standards apply?
- Urban planning requirements?
- Energy requirements?
- Weighing up the priorities in the “magic triangle” of quality, costs and duration
- Definition of an objective as a benchmark for all subsequent planning phases
- Development of the evaluation criteria as expert assessors in architectural competitions
We design different variants based on the strategic objectives, we identify their advantages and disadvantages and keep on developing the preferred solution.
- Sketches of concepts drawn by hand
- Taking into account different options for materials and the construction
- Inclusion of structural and thermal loads
- Dependencies in the building structure are taken into consideration
- The physics of the building and acoustic requirements are taken into consideration
- Fire protection and smoke extraction are taken into consideration,
- Cleaning and maintenance plan, access at heights
- Outlining solutions, costs and timings
- Inclusion of existing solutions to clarify the design
- Support during the initial sampling
- Documentation in report form
- Ongoing updating or further development of the design
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.
- Detailed hand-drawn sketches
- CAD-based layout plans and CAD-guided details
- 3-dimensional analysis of the shell of the building for complex facades
- Selection of the materials and type of facade
- Drafting of the facade plan on the basis of the building physics and acoustic specifications
- Integration of fire safety and smoke extraction plans
- Security requirements are taken into consideration
- Collaboration on the overall design so that it can be approved
- Joint design, joint width and depth in accordance with the building movements identified and relevant tolerances
- Documentation in report form
- Ongoing updating and further development of the design, cost estimate and construction scheduling
- Support in the planning and implementation of 1:1 facade samples to ensure that the design is progressing as intended, e.g. in design-and-build processes
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.
- Guide-detail planning as CAD drawing on a scale of 1:1 with all connections to adjacent components
- Detailed representation of the layers, components and individual components of the facade solution supplemented by material descriptions and dimensioning
- Planning on the basis of static pre-dimensioning for the relevant facade components – glass, profiles, fixings
- Advanced planning for the building physics and acoustics
- The specified security and fire safety requirements are taken into consideration
- Planning and integration of control and operating components
- Updating costs and the construction schedule
- Agreed plan for the materials
- Glass specifications
For tendering and awarding contracts Priedemann defines and specifies the planned facades and details as well as the connections to adjacent components.
- Summary of technical requirements as well as client and user specifications for construction and materials as “Technical Preliminary Remarks”.
- Compilation of the design and additional technical criteria in coordination with the planning team
- Drafting of the service description
- Individual quantities and components are recorded
- Differentiation of the various trades when awarding contracts to different contractors, clear definition of the interfaces
- Collation of all documents in a single set of documentation
Priedemann provides clients with comprehensive advice independent of individual manufacturers and systems when selecting the best award procedure and the most suitable manufacturer.
- Comparison and evaluation of the tenders that have been submitted
- Creation of price comparison lists
- Evaluation of alternative providers
- Evaluation of the qualification certificates of the facade manufacturers
- Assessing the capabilities and capacities of potential contractors
- Involvement in the discussion when contracts are awarded
We know the market: Our experience from hundreds of projects with various manufacturers is incorporated into our consulting services.
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- Verification of compliance with the approved design, ensuring compliance with the agreed qualities, standards and test series
- Regular reporting on production progress; the reports contain recommendations for possible improvements as well as a list of unfulfilled services, performance arrears, defects identified
- Verification of compliance with the approved design, ensuring compliance with the agreed qualities, standards and test series
- Inspection of examples of facade sections as reference values for determining the quality of workmanship – benchmark inspections
- Involvement in performance tests on the facade on the building site (water impermeability, sound insulation, blower door test, etc.)
- Random inspection of the installation work on the building site
- Regular reporting on the installation work including the identification of discrepancies with the original planning
