Peruvian Institute of Neoplastic Diseases – Torre Esperanza (Hope Tower)

Key data

The National Institute of Neoplastic Diseases (I.N.E.N.) is the first national institution for oncological treatment, with cancer prevention, detection and treatment services, through surgeries, endoscopies, chemotherapy, nuclear medicine, disease palliation etc.

The building measures over thirty thousand square metres, dedicated to the care of the population and will tend to an average of 250 thousand patients per year.

System implemented

Comprehensive steel construction service: Supply, fitting out and industrially reinforced steel reinforcement, and installation of the steel already sized and/or reinforced “in situ”, of the various structures which made up the work.

The project execution works were undertaken according to the following guidelines:

  • Shoring the ground by means of walls anchored to the ground.
  • Excavation below level «0» was carried out until three basements were completed.
  • From the level of the foundations of the last basement, tower cranes were installed to shore up the undertaking of the work. From the foundations emerge the vertical elements – industrially pre-assembled in the workshop and served and spliced on site – and the horizontal elements (solid slabs in the basements and waffle slabs in the rest of the levels).
  • On the levels earmarked to nuclear medicine, the floors and walls had to be reinforced with much stronger concrete structures in order to absorb the radiation which is emitted internally.
