Thread: Estimating costs of new street construction

  1. #1

    Estimating costs of new street construction

    Looking for some help... Is there a way I can estimate the cost per sq. foot of a two lane residental street, constructed of asphalt with curb and gutter, meets Class-A all-weather standards, constructed on farily flat terrian?

    The best way is to call a city nearby that has done one recently. The costs are too varible to estimate otherwise.

    For a newly platted subdivision or in an existing area? Right-of-way required? Utilities or utility relocation? Catch basins and storm sewers? Street lights? Curb, gutter, and sidewalks?

    giff57 is right -- it's probably easiest to contact a community or developer that has done one recently and see if they will give you a 'ballpark' estimate.

    Upgrading an existing two-lane, in an urbanized area, to two 12' lanes, including acquiring r-o-w, utility relocation, curb, gutter and 5'-0" class "A" concrete walks will easily run $1M a mile.

    Griff & Gedunker have it. Costs vary wildy. Even on relatively flat terain you will have issues with sub-base, in some places you may need to do quite a bit to prepare the soil, in others, not so much. Other things to consider include drainage. With C&G I would assume you would need catch basins and a drain system. That will signifcantly increase the cost of the project. In addition, will this be built to AASHTO standards?

    Not to mention the impact in general of the construction market. Contractors will bid much more competitively when they're hungry...
