D7R dozer is also being used. The two pieces of equipment are not, however, <br />being used during the same construction season. The task states that the D"IR <br />dozer, in conjunction with the 315C excavator, will be used in the first five <br />years of the extended liability period for rill and gully repair (for 80 hours <br />each year). This is the period when vegetation is not yet established and <br />extensive erosion damage is possible. The D3C dozer is then used for the <br />remaining five years of the extended liability period (for 40 hours each year). <br />During this time, vegetation should be fairly well established and erosion <br />damage should be minor and limited in nature. The Division will not adjust <br />this task. <br />14 <br />
