ADD - SDOT Standard Plan 410 and 411 to the Special Provisions
II. Reason and Background for Change
SCI and Salinas proposed this change initially. Typical construction sequence when using cement concrete curb and
gutter and PCCP roadway is to install the curb and gutter before the PCCP roadway. Using a 410C curb type allows
PCCP roadway to be installed before the curb, and the curb can be installed after vehicles are using the new pavement
surface. This shortens the time vehicles are traveling on the temporary gravel surface. This also creates wider outside
concrete panels, going from approximately 9' wide by 12' long, to 10.5' x 12' long, creating panels closer to square in
dimension, which potentially increases their strength. Under the traffic island, the use of a traffic curb would result in
6' wide x 12' long panels. KSP 5-05.3(8)require the larger dimension to be no greater than 150% of the smaller
dimension.
The City specified WSDOT standard 1.5" dowel bars for the PCCP roadway. The City reviewed this with their
geotechnical and pavement design consultant and determined 1.25" dowels would be more appropriate for the 8.5"
pavement thickness specified in the contract. The City and Contractor agreed to a credit for this change.
SCI initially presented this change proposal, including the dowel bar credit, to the City with a total cost of$5,487.44.
The City countered at no cost, as the per plan design has worked successfully in the past. The Contractor then agreed
to make these revisions at no cost.
