We provided
Consultancy
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
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 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- Checking that the documents provided are complete
- Comparison with possible project changes and updates
- Determining the status quo for the start of construction
- Checking the system components to be implemented
- Clarification of unresolved questions, communication with the planning team
- Priedemann checks and comments on the contractor’s structural assumptions as well as the performance in terms of energy and acoustics
- Checking and evaluating the contractor’s work schedule
- Checking relevant facade elements and how they interface with other trades
- Evaluation of the contractor’s planning and system design
- Checking of technical specifications for materials such as glass, stone etc. as well as data sheets for sealing and insulating materials, surfaces, system descriptions etc.
- Checking and assessing the facade supply chain for compliance with the applicable guidelines as well as technical and quality standards
- Comparison of test data with specified or actual performance data
- Updating change management
- Investigation of options for production, materials and technology, if necessary making improvements whilst retaining the agreed qualities, costs and dates for implementation
- Evaluation of facade materials that the facade manufacturer provides as an IFC (issued for construction) alternative
- Statement on the suitability, quality and equivalence of alternative material proposals in relation to the materials in the original plans
- Assessment and evaluation of the behavior of the products when processed
Scale does not just changes the perspective and the proportions, only in the 1:1 model can the loads a component is exposed to be tested realistically.
Usually, mock-ups are only created after being awarded to the manufacturer of a facade. We support the planning and implementation already during the planning phase in order to ensure greater reliability of planning, design and implementation at an earlier point in time.
- Support and advice when carrying out facade tests
- Control of the standards and requirements to be met, involvement in tests
- Evaluating and commenting on the test reports
- Recommendations for potential improvements
- Support and advice on the construction of a facade sample to match the design requirements
