Description
For $29,257.15 in additional payment authority for Contract 146646 for Change Order 2, for additional construction administration and design work for the Aviation Department. This work was required due to a change in soil conditions and a change in grade elevation for a utility structure during construction of the Phoenix Goodyear Airport Taxiway A Rehabilitation and Strengthening Project AV41000075. The contractor encountered saturated soils requiring additional work by the contractor and the engineer to develop solutions to overcome subgrade failures caused by excessive moisture. The frequency and severity of storms that occurred during construction required remediation of the soil to stabilize the subgrade and meet the project requirements.
