At Boston Sand and Gravel, Massachusetts the challenge was to increase production and retrofit an existing plant located right in the middle of the city in order to gain maximum capacity for 24 hour batching for the BIG DIG, while retaining many of the older facilities.
The original dry loading bay and weigh hopper were preserved; additional cement storage, high-speed conveyors and a 12 yd³ reversing drum mixer were added.
