Thanks to innovators at Goodeve Manhire Partners, the structural design company of the project, most drop panels in the cast-in-place structure were eliminated. "Drop panels are expensive" explains Yves Taillefer, director of estimating and design at Brigil. "We like shear rails because we can save money and time on formwork while helping our architects and engineers with their design" adds Mr. Taillefer. Indeed a slim concrete floor gives more freedom to designers: especially in projects with exposed concrete ceilings.
