Construction Contributions Drive Hospital’s Rise in Haiti

Constructing any major hospital is a challenge, but building a 320-bed state-of-the-art teaching hospital for $16 million in the highlands of Haiti is fraught with difficulties.

Construction of the 180,000-sq-ft teaching hospital for all of Haiti began in July. Plans call for it to be operational by Jan. 12, 2012. Despite challenging conditions, including a refugee crisis and a raging cholera outbreak that began in a camp a mile away, work is well under way. “We are about to pour our first big roof slab, which is a milestone,” said Ansara in early April. “It is a complicated slab—complicated reinforcing for what is normally done on the island. We are very particular about connections between beams and columns, which is really important seismically.”

Even with the oversight of a fairly well-trained general contractor and engineers brought in from the Dominican Republic, it is a challenge to create reinforcing plans that can be executed by untrained workers, says John Looney, principal of JML Engineering, Winchester, Mass., the structural engineer. “The labor pool in Haiti is extremely unskilled,” he says. Designs for roof slabs, such as the one about to be poured, need to be straightforward so that they can be applied to all situations. While a more complex solution may require less rebar, it is more prone to error.

Looney says the hospital’s 24-ft to 28-ft spans and load-bearing walls are unlike the 10-ft by 10-ft unreinforced modules that typically are found in Haiti. “Imagine a table with four legs on it … a building that is a concrete slab with ring beams around it and four columns. For a larger building they add more modules. To go taller, they stack them up,” Looney says. For full article click here.

  • Private Residence
    Mattapoiset, MA

    The plan of the house is a cruciform with spaces, which radiate from a central mechanical core. The shape of the house reflects a simple pyramidal form. Each side of the pyramid varies slightly, reflecting the functional changes taking place within. The house steps down following existing grades allowing higher ceilings in more active areas. Over the center of the roof is a widow's walk, which affords 360-degree views and gives the house a traditional seaside appearance. This space is also the natural ventilator for the house, allowing through-breezes to cool it.
