The City negotiated the compensation prior to the contractor's completion of the work. The work items are as follows: 1. As described in Change Order No. 1, the contractor disposed of material excavated from Aqua Lane off of the project site. As there was no bid item for this work, the contractor is being compensated on a time and material basis as detailed on the attached invoice. The total additional cost is $1,522.50. 2. In order to place the bituminous wearing course on the roadway areas, the contractor must adjust the manhole castings upward such that they match the new surface elevation. This adjustment involves exposing the manhole casting, "rolling" down the rubberized manhole seal, adding a concrete adjusting ring beneath the casting, replacing the casting, "rolling" up the seal, and backfilling/compacting the disturbed area. Of the 67 manhole castings to be adjusted; 36 required an additional section of rubberized seal, and 18 required additional excavation to extend the seal onto the top of the manhole cone. As this involved more work effort by the contractor than was expected in the contract, the contractor was compensated an additional $200.00 for each of the 36 manholes, and an additional $300.00 for each of the 18 manholes. The total additional cost is 36($200.00) + 18($300.00) = $12,600.00. Total Amount of Change Order No. 2: $ 1,522.50 $ 12,600.00 $ 14,122.50 An Equal Opportunity Employer
