DISCUSSION:
On September 25, 2007, the City Council authorized the award of the Superior Avenue
Median Improvement project to GMC Engineering, Inc. The contract provided for the
construction of new landscaped medians on Superior Avenue from Ticonderoga Street
to Dana Road. The contract has now been completed to the satisfaction of the Public
Works Department. A summary of the contract cost is as follows:
Original bid amount: $634,118.50
Actual amount of bid items constructed: $629,989.80
Total amount of change orders: $11,439.25
Final contract cost: $641,429.05
The decrease in the amount of actual bid items constructed over the original bid
amount resulted from the reduction of plant material. As part of the original contract,
the contractor was required to lay out a sample 200 feet of plant material for City
approval. During our review, we noticed that some of the plants were too close
together. Upon consultation with the landscape architect, staff made a field adjustment
which reduced the number of plants to allow for proper growth. This resulted in a cost
savings in plant material. The final overall construction cost including three change
