BACKGROUND/ANALYSIS: On August 24, 2010, the City Council awarded a contract to Vincor Construction, Inc. for the McCoy Equestrian Center Site Improvements project. On January 11, 2011, the City Council approved Change Order No. 1 in the amount of $95,142.02. The majority of the additional costs were associated with expanding the size of the arena from 100 ft. by 200 ft. to 135 ft. by 250 ft. Since that time there have been a number of small changes to the work which necessitate a request for a second change order in the amount of $5,242. These changes include: • An additional 130 LF of 6-inch sewer line and adjustments to the grade of the existing sewer line to achieve proper flow. Additional cost: $12,438. • Providing and installing a new circuit breaker and related, ancillary material in the existing cabinet adjacent to the new storage building. Additional cost: $3,580. • Modifying one of the Musco light poles to address differing site conditions. The contractor encountered rock prior to achieving the optimum depth of the pole and had to shorten and re-coat the pole prior to installation. Additional cost: $1,000. • Modify the dust control for the new arena by upsizing the pipe to 1-1/2 in. diameter pipe and using a larger, type 1-90 irrigation head. Additional cost: $1,760.
