smaller and smaller in relation to the level of the roadway. In such instances, the old pavement needs to be removed prior to curb and gutter work. On Black Avenue the old pavement was successfully removed, allowing reuse of the existing curb and gutter, at a significant cost savings. In removing the pavement in the gutter pan on Division Street, it was discovered that the existing curb and gutter was not monolithic (i.e. built as a single unit). Instead, the gutter was constructed independent of the curb, and in fact, the gutter portion has settled. Additionally, the pavement thickness constructed over the concrete gutter varies from 1 inch to 5 inches and the curbing was constructed 8 inches tall instead of 6 inches (see Figure No. 3). As a result of this discovery, greater quantities of asphalt and additional curb, gutter and adjacent sidewalk and driveway, will need to be removed and replaced. The estimated cost of this additional work is $65,000, the anticipated amount of proposed Change Order No.1, to the Vanguard Construction contract. Staff recommends authorization to execute this Change Order and the transfer of $65,000 from the Annual Street Resurfacing project and leaving intact the original project contingency amount of $49,550 for additional work or changes that occur during the construction phase.
