Description:

The Hospital General Universitario Gregorio Marañón (HGUGM) is one of the biggest hospital complexes of the Public Healthcare System of the Comunidad de Madrid. Its origins go back to 1567. An endless amount of relocations and mergers with other assistance centers, plus several and diverse architectural restructurings, have derived into a complex setup of circulations, assistance spaces and departments in the more than 20 buildings which nowadays make up the hospital.

The block, surrounded by the streets Doctor Esquerdo, Ibiza, Maiquez and Doctor Castelo, is organized placing several buildings in line with these streets. The middle of the parcel is taken up by a set of three buildings (IPMQ, Clinic & PASA), which setback from Docotor Esquerdo street to take in the main entrance.

The building lot for this operation is part of the free space in the hospital enclosure, west of the Ambulatory Assistance Pavillion (PASA), whose partial reformation is also part of the project.
The IPMQ (Medical-Surgical Provincial Institute) is the main building of the complex and contains seven floors above ground (ground floor + 6), lower ground and basement, for a total of nine storeys. The lower floors (up to ground floor) are composed by perimetral blocks forming an octagon and two perpendicular blocks in the center, making four pentagonal courtyards between them, while the higher floors (from first floor) do away with the external blocks, with only the central blocks rising up in a cross, which feature a central communication. At the southwest side of the octagon the rectangular block gives way to a five storey cylindrical block attached to the rest of the building.

The projected operation entails the Reform and Expansion of the current PASA to build a new Surgery Block, made up by 30 operating rooms, with their corresponding support and post-surgery areas, in the remaining free space from the building to the inner avenue, to increase the available space per floor of the operation, minimizing the surface increase of the current building so as to unify all of the hospital’s operation rooms, nowadays scattered throughout different buildings, as well as the post-surgery recovery and support spaces, to improve the assistance quality and optimize its performance. This new block will contain most of the new operating rooms in the higher floors and will serve to completely free up the first floor of the PASA, relocating in the new block the affected services in the current building.

The different areas of the program will be distributed among the floors according to their functional necessities. As such, existing services will be relocated to the lower floors, improving their current conditions and freeing up spaces needed for the reform.

The shape of the free space in which the new building will be constructed is almost rectangular and the area it will take up is approximately 900 m2.

The total built surface is gauged at 14.418 m2 and the material execution estimate is 14.339.491€

The production is carried out maintaining assistance activity at all times, which involves an added complexity that has been considered by dividing it, therefore, in 3 phases.
The Project contemplates a planification of up to 22 months, although it accounts for two months between the three phases proposed for the corresponding transfers, so the net duration of the operation would be of 20 months distributed among the three phases as follows:

- 1st phase. 9 production months
- 2nd phase. 6 production months
- 3rd phase. 5 production months
