Botton-Champalimaud Pancreatic Cancer Centre

The building is made up of five independent structural modules. In order to make this project viable, a 1200x1900 mm ovoid collector crossing the site had to be diverted to Av. da India (the bicycle path area). The building is divided into 5 floors, with the two lower floors being used for car parking, technical spaces and storage areas.

The work was divided into 3 phases.

Phase 1

To carry out the work, a variable excavation of approximately 2.5 metres to 6 metres was made, combined with a previous excavation of 1 m. Taking into account the existing confrontations, the excavations for the building's boundary walls were subject to special peripheral containment processes of pile walls type. The foundation piles were also carried out at this stage.

The work involved the construction of 800 mm diameter secant piles, 70 centimetres apart and self-supporting, with lengths varying between 5 m and 12 m. The curtain wall piles will be self-supporting. The pile walls will be self-supporting, headed by a capping beam with a cross-section of 0.85 x 0.8 m2.

The foundation piles were made up of ∅600mm and ∅800mm reinforced concrete piles with lengths varying between 7.5m and 12m. Micropiles for the foundation in module E had lengths varying between 13m and 15m.

Phase 2

Phase 2 was a continuation of the excavation and containment works of the previous phase.

The work consisted of the following tasks:

• Demolition of the cap of the foundation piles (carried out in Phase 1);

• Earthworks (opening up the foundations);

• Reinforced concrete structure;

• Metal structure;

• Earthing networks.

The building consists of a reinforced concrete structure and a metal structure, with solid beamed slabs, ground floor paving, sun shading slab, solid foundations and beams, columns, walls and reinforced concrete cores, as well as a metal deck-type roof on the ‘Penthouse’ floor with a metal support structure of beams and pillars.

The pillars and load-bearing walls were mostly made of reinforced concrete, mainly being more architectural than structural. This is the case with the separation wall between the exterior and the high building with large elliptical openings, made of reinforced concrete similarly to the existing wall in the main building of the foundation on the Tagus River side. Likewise for the metal pergola, which is also similar to the one on the main building but located on the opposite side.

The curved exterior wall in this project, unlike the main building of the Foundation, was clad on both faces.

The metal beams were connected to the reinforced concrete elements either by metal connection plates and chemical anchors or by metal plates with rag-bolts, to be left in place during the concreting of the structural elements that support them. Finally, this phase included work on the building's glazed façades and their cladding in lioz stone with a sawn finish.

Phase 3

Phase 3 continued the construction of structures from the previous phase.

The building is divided into 5 floors, the lower two of which are used for car parking, technical spaces and storage areas.

This phase of the work consisted of:

• Demolition to adapt to the new building in the peripheral connection areas;

• Excavation and reinforced concrete in a partial exterior area to the existing building, not included in Phase 2;

• Masonry of ceramic bricks, concrete blocks, and blocks with radiological protection;

• Painted plasterboard partition walls;

• Acoustic partitions;

• Insulation and waterproofing;

• Thresholds, window sills and stonework cladding;

• Fire-resistant, flame-retardant and airtight openings;

• Various carpentry (cabinets, benches and tops, furniture, counters, shelves, finishing strips, locker room benches, and wall cladding);

• Various metalwork (pergola, cappings, benches, fencing, and stairs);

• Glass openings;

• Interior ceiling cladding with painted plasterboard, mineral fibre boards and wood;

• Exterior ceiling cladding with plasterboard;

• Interior wall cladding with paint on blocks and plaster, painted stucco, vinyl, ceramic, glass, wood veneer and lead;

• Exterior wall cladding with stapled stone on a ventilated façade;

• Interior floor covering with vinyl, ceramic, parquet, carpet, technical flooring, epoxy and metal grating;

• Exterior floor cladding stonework and tiles;

• Walls and floors painting in the car park;

• Sanitary ware and equipment, lockers and benches, glass and mirrors;

• Blinds;

• Car park equipment;

• Façade cleaning system;

• Electrical, security, telecommunications, mechanical, hydraulic, natural gas and medical gas installations;

• Lifts, escalators, walkways and platforms;

• Pneumatic conveying system;

• Landscaping (pavements, drainage, walls, planters, bins, irrigation network, and gardening).

The floor designated for car parking and technical areas has two connections to the existing building: one for vehicles to the current parking area and another at level -0.60 for service and patient access between the research centres.

The connection to the existing building via a tunnel is ensured by the implementation of two moving walkways according to the specialised project.

This floor has 218 car parking spaces and 18 motorcycle parking spaces. It is designated for parking, technical areas, storage, and a sterilisation area with a connection at level 2.30 to the existing building.

There are five vertical access zones to the Pancreatic Centre plus two designated for emergency exits. At the connection to the existing building at level 2.30, which is fully underground, there are compartments dedicated to technical and sterilisation areas serving the entire building. This floor has 136 car parking spaces, 41 for electric cars, 3 priority spaces, and 3 for limited mobility, 33 motorcycle parking spaces, and 55 bicycle parking spaces.

This floor is at the entrance of the new pancreatic centre with a lobby and access overlooking the interior lakes in the courtyard, created by the arch wall lined with lioz stone and the ellipses lined with stainless steel.

In the eastern circulation areas, the corridors are large and house the Day Hospital receptions as well as the multidisciplinary clinic area.

The Day Hospital will have 24 chemotherapy stations, a room for individual treatment, consultation and nursing offices, clinical pathology collection stations, a reserved waiting area, as well as all the necessary support and sanitary facilities, some of which being suitable for patients with reduced mobility.

The Multidisciplinary Clinic area will have 20 consultation offices, 2 observation rooms, 1 nursing office, and sanitary facilities, including facilities for patients with limited mobility.

The open-plan administrative area includes 2 meeting rooms.

There is also a cell processing research laboratory. The Research Laboratory is intended for the study of pancreatic cancer with all support areas and offices.

This floor houses the Surgical Centre with two operating rooms. Public access is provided via two lifts and a central escalator.

In the eastern area, there are 29 inpatient rooms, of which 4 are isolation rooms with positive pressure, 2 with negative pressure, and 2 nuclear. In this area, there are 4 control stations with respective work areas, a medication room, a medical office, and a nursing office, as well as all support services.

In the surgery unit, there are 2 operating rooms, 2 individual preparation areas, changing rooms, 9 individual Intensive Care Unit (ICU) rooms, and 6 recovery rooms, as well as control stations for all service areas attached to this unit.

An expansion area has been considered on this floor so that the surgery area can be extended according to future needs.

This floor only has an administrative area (administration offices) and a technical support area for the entire pancreatic centre.

The administrative area has a raised floor 0.35 metres above the finished floor level.
