The project involves the design of a public olympic pool for the expansion of an existing swimming program of the Municipality of Humacao, Puerto Rico. It is located in an unfinished parking lot serving a newly developed Coliseum to the north, with a water creek bordering from south to west, and to the west, a newly inaugurated Fine Arts Center. With a 1000+ people capacity, longevity and minimal budget were the client's primary concerns, as is typical of public architecture developments throughout the country. As a result, most spaces employ natural ventilation, with the exception of the gym and small offices, and the principal surface finish is exposed concrete. However, we strived to propose a contemporary solution, with precast elements and the aid of pattern-generating algorithms.
