For Metro Detroit the winter of 2013-14 was the second snowiest season on record, bested only by the winter of 1880-1881. This had a terrible effect on the city’s roads and in the suburb of Southfield, officials assessed the poor state of the asphalt and concrete streets and realised the conventional patch and fill programme would not be sufficient.Instead the contract was modified to cover mill and resurfacing the numerous asphalt and concrete roads throughout the city. Local contractor Allied Construction was brought in to carry out the work within a short timescale.
The contractor was given a list of project streets at the beginning of the month with the mandate to keep traffic flowing and to minimise the time at each location. As the company completed the first projects on budget and within the 15-day completion windows provided, the authorities extended the contract and added new sites to the repair/reconstruction list.
