Procurement structure in Slovakia The weight of particular information flows during the procurement process Peter Matiasovsky Institute of Construction and Architecture. Slovak Academy of Sciences
Design steps • Providing of the input data • Pre-design documentation for the decision about location of a building • Documentation for a building license • Detailed documentation • Documentation for a construction • Documentation of the actual state after a construction process
Triangle of a design processPerformance simulation and modelling of the system: Environment – Building – Structures – Materials ... - User • Iterative simulation • - Whole building performance • - Structural/detail performance • Modelling • Parameters: • Material • Geometry • Boundary conditions: • Outdoor • Indoor
Influence of particular procurement phases on the PBBBC – Boundary Conditions for simulation , PBD – Performance Based Design, PBM – Performance Based Manufacturing, PBU – Performance Based Use
Databases • Codes, regulations and standards • Urban plan, boundary conditions (geology, hydrology, climatology, etc), building typology • Building performance simulation models and tools, databases of material parameters and boundary conditions • Construction information systems, catalogues of buildings, building parts, products and materials • Data for a whole building performance simulation
Conclusions - barriers to the performance approach • Lack od a complex system of construction information (in comparison with the previous period) • Incompletness of the widely available knowledge, tools and databases for complex performance simulations • Lack of the stimulation/funding/competitivness
