Change in Work:
Revise pavement structural sections $556,000.00 Description of Change:
Due to the unavailability of suitable material at the mandatory borrow site, it is necessary to revise the structural section for hot mix asphalt pavement for the roadway widening, shoulders, and ramps. A portion of the change in work was previously approved under delegated authority in the amount of $180,000 to stabilize the subgrade. In order to complete the work, an additional 556,000 is needed. This exceeds the Director’s delegated authority limit and requires the Board’s approval.
The cost for this work is based on Section 3 of the contract specifications. No additional working days will be required because of this change.
Sufficient funds for this project are included in the Fifth Supervisorial District’s Transportation Improvement Program in the Road Fund Fiscal Year 2015-16 Budget. The Road Fund will ultimately be reimbursed with Westside Bridge and Major Thoroughfare Construction Fee funds as fees are collected.
