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

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 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
While the work is being planned
  • 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
Additional services
  • 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.

Physical mock-ups:
  • 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
Visual mock-ups:
  • Support and advice on the construction of a facade sample to match the design requirements

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
Regular inspection at the building site
  • 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

Value Engineering is part of the Priedemann DNA. We ask about the motives and objectives of a project: Which functions should the facade fulfill, which requirements? What is the design requirement? Based on this, we develop alternatives and evaluate these options with regard to any possible improvements that can be made to the overall solution. At the same time, we take into account the criteria of the entire building life cycle.

The aim is to provide a transparent basis for making decisions in order to make them easier for our clients. This minimizes risks, bad planning and poor decisions. Simultaneously we improve the calculability of the overall project and save time in planning and execution. We see value engineering as a fundamental component in overall planning which helps optimize all processes and procedures.

Specials

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.

  • Moving components: Facades today contain a large number of movable and electrical components. Individual components require regular maintenance. This needs to be taken into account right from the start.
  • Glass: Glass can be damaged, replacing glass must be possible at any point with reasonable effort. Today, individual panes weigh several hundred kilos, floor-to-ceiling triple glazing weighs up to one ton and more. We plan the right solutions for this.
  • Cleaning: Glass cleaning and the cleaning of horizontal surfaces are part of regular operating expenses. We provide simple, secure access with as little technical effort as possible. We make cleaning recommendations and create complete cleaning plans right up to the choice of cleaning agents and necessary intervals with which cleaning can be carried out most effectively.
  • Facade development: We plan all facilities for the development of the facade areas, determine the loads of fall protection systems, walkways and access systems and consider the points of contact and passage through the facade to the building shell during planning.
