Authorize the execution of Change Order No. 2 in the amount of$175,653.75 to City Secretary Contract No. 41807 with Conatser Construction TX, LP, for Sanitary Sewer Rehabilitation Contract 56, Part 2, thereby increasing the contract amount to $868,088.75. DISCUSSION: On May 17, 2011, (M&C C-24912) City Council authorized the execution of a contract in the amount of$696,387.00 with Conatser Construction TX, LP, for Sanitary Sewer Rehabilitation Contract 56, Part 2. The contract was subsequently revised by one change order with a credit of$3,952.00 administratively approved by the City Manager on September 6, 2011. During sewer installation, existing wet soil subgrade was encountered on the project streets that caused backfill material to fail density testing.

The total cost of work under this change order is $175,653.75. Taking into account the previous credit of$3,952.00, the total contract amount will be increased by $171,701.75, or 24.66 percent.
