This paper is based, from a general point of view, on a project for the construction of a large span hangar for United Parcel Service. The design and construction stages, the space and material requirements, and the challenges faced in carrying out this type of project are analysed. The work continues with a brief feasibility analysis of the project. This study provides an overview of the current situation at Cologne airport with traffic statistics for the last few years and how this traffic is likely to develop in the future. It also studies the company's traffic volume, as well as its evolution and incident data in order to economically justify the realisation of this project. With this data, a strategic profitability map and costs estimations are made in order to evaluate whether it is worthwhile to continue with third-party maintenance or, on the other hand, to invest in the construction of a hangar, i.e. a major capital investment. Several factors are then considered, such as the size of the hangar, the height of the structure, the space requirements for the aircraft, the type of construction material and safety requirements. The hangar structure will be made of structural steel, which is a strong and durable material. Prior to the design of the structure, a geotechnical study is carried out, along with a study of the different aeronautical easements that may affect the dimensions of the building, as well as a preliminary layout and a building use plan. It is also taken into account that the building will be located in another country with different construction regulations. In terms of structural design, a truss gantry frame typology is used to lighten the weight of the structure. An inverted T shaped aircraft entrance gantry is designed, with a vertically opening canvas door. On the other hand, the foundation of the structure is calculated using insulated shoes and bracing beams, in addition to the provision of a reinforced concrete paving slab for the interior platform of the hangar. In order to give the work a broader scope, a design of the main installations of the structure is made and a general budget for the project is drawn up. Finally, the plans of the structure are annexed together with the plans of the installations.

This document presents a project for the design of a hangar for aircraft maintenance at Reus Airport. Two main objectives are established: --On the one hand, define the feasibility of the proposal, taking into account a 25-year horizon in which a traffic forecast and a profitability analysis are developed. Finally, the proposal is complemented with the case study of the Ryanair hangar located at Sevilla Airport, which can facilitate decision-making in some further sections of the project. --On the other hand, obtain a structural design proposal that can really adapt to the airport environment, considering all possible factors for the calculus and needs of the infrastructure. To carry out the first point, a brief study of the current situation of the airport was executed. Later on, the airport's available growth capacity was analyzed and the expected annual operations and passenger flow were projected. In addition, in the economic analysis, following the forecasts analyzed above and after obtaining costs, revenues and profits, the aim is to delimit the profitability indicators (NPV, IRR and Payback) in order to be able to conclude the viability of the project. As for the structural design, a solution has been chosen using a metallic structure, porch type with trusses and sandwich panel enclosures. In addition, the foundations of the structure are calculated and a slab is proposed for the paving of the hangar. Prior to the design and calculation of the structure, the needs and design requirements of the hangar are introduced, analyzing factors such as the geotechnics of the terrain, the restrictions marked by aeronautical easements or the type of aircraft maintenance foreseen. Finally, different hangar facilities are designed to make the project more plausible and to limit the values of the final budget presented as much as possible. Finally, two documents associated with this report are presented, Document II. Annexes, in which the characteristics of each section are analyzed and described in greater detail, and Document III. Plans where the entire hangar design is graphically depicted.
