Engineer: Nussbaumer & Clarke, Inc.
The Ferry Grider Buffalo Municipal Housing Authority (BMHA) projects were originally constructed in the 1950’s. This is the first inner city reconstruction project performed in the area since then.
The scope of this 5 million dollar project replacing more than 15,000 SY decorative concrete pavement roadway, including concrete curbs and gutters. The decorative, exposed aggregate pavement on this job is used as a maintenance access road that runs through the middle of the complex and around the entire perimeter for property management personnel to maintain easy access into each courtyard.
Traffic flow and access were very critical for the residents in this complex, so Surianello used a mixture of high early-strength concrete, which allowed quick reopening and reduction of traffic congestion. Quality, safety, cost efficiency, and adherence to the project timetable also were important factors, as were the aesthetic qualities of the decorative concrete. In fact, noting the importance of the aesthetics, Surianello presented the pavement monthly to the Housing of Urban Development for acceptance.
The original spec for placing exposed aggregate pavement was used for the reconstruction project. It would have required pouring 5 in. of concrete, then seating 1 in. of aggregate, a method similar to those used to build many sidewalks.
Instead, Surianello suggested eliminating the separate aggregate seating process by spraying a retarder on the finished surface, and then, power washing it three hours later to achieve the same etch in the exposed aggregate. Surianello reasoned this also would improve the structural integrity, while also imparting a more uniform appearance.
