The incorporation of materials, techniques and mechanisms into engineering most innovative constitutes one of the most revolutionary creative processes, changing the rules within the field, leading to a variety of responses facing the problem raised. This gives rise to the use of materials such as fibers and resins in the structural solution of the building, to the use of modern home automation to create spaces where all facility parameters are controllable, achieving bioclimatic and environmentally friendly realizations. In this field, ARQTEL distinguishes three areas of action. A first intended to the design and structural calculation of different structural typologies applied to the building, as well as structural rehabilitation projects. In this field of action is collaborated from the preliminary project to the end of execution, carrying out the Project Management of the implementation. A second would cover the functions of Technical Building Control Office, which allows us to collaborate with numerous clients carrying out the technical control of the execution, as well as with insurance companies that need to carry out necessary controls to contract the ten-year insurance of the works. A third area of expertise would be in Installation Engineering, which allows us to design and calculate the systems for air conditioning, water, electricity, security, gas, fire protection, home automation, and new technologies in all types of buildings, collaborating from preliminary studies to construction management and commissioning verification.
