Quality and Safety in construction projects is ensured through careful planning, scheduling, execution and control of the work. The certification of construction professionals with specialised knowledge of the construction and legal framework is considered essential both to ensure quality and safety in construction and to protect workers, users or the general public. The construction industry has a direct impact on the daily lives of modern people, with the result that a lack of quality at any stage of construction can lead to serious accidents and damage. In addition, poor quality work and lack of expertise potentially results in financial and human losses. With the demands in the modern construction industry being strictly increased, the provision of work by construction professionals needs to offer all the necessary guarantees to ensure quality and safety. The certification of the professional strengthens his professional identity and validates it through the monitoring of new technologies (spectroscopy, machine learning) to detect control, quality and the required project specifications. In this way, it becomes established on the labour market. In addition, continuous training promotes the development and competitiveness of workers and companies in the construction sector by upgrading professional knowledge and skills. Certification is a stepping stone, opening up new opportunities in the construction sector and concerns specialisations such as: Certified expert Building Information Modeling (ce-BIM), Insulation Technician-Masonry Technician, Carpentry Technician, Masonry Technician, Coatings Technician, Painting Technician, Dry Building Systems and Related Fireproofing Systems Technician, Ceramic Tile Installer, Concrete Moulding and Injection Masonry Technician, Concrete Reinforcement Iron Installation Technician, Fitting Technician, Plumber, Project Machinery Operator, KNAUF and THERMOPROSOPSIS KNAUF Ready-Mix Plaster Technician, KNAUF Ready-Mix Plaster and THERMOPROSOPSIS KNAUF Plaster Technician, KNAUF Fireproofing Specialist, Geographical Information Systems- GIS Specialist, Explosives and Grouting Management Specialist, Project Management Executive, Integrated Automated Design and Project Management Systems Specialist, Smart Buildings Planning Specialist, Leveller, 3D Design Specialist, Smart Urban Infrastructure Management Specialist, Facilities Management Specialist, Construction Protection Technician
