Title
Action to approve Resolution 20-047, a Resolution Authorizing Change Order No. 1 for the 2019-03STI, 20th Street South Improvement Project; Bowes Construction Co., Inc.
Body
Summary:
This project is the reconstruction of 20th Street South from Main Avenue to Rio Grande Avenue. The project involves storm sewer, water main, sanitary sewer, grading, curb & gutter, asphalt paving and a new 8’-wide concrete shared use path along the south side of the street.
It was found that the water table is very high in the area along 20th Street South between Rio Grande Avenue and Western Avenue. The geotechnical engineer recommended to install drain tile along 2,000 feet of 20th Street South to stabilize the subgrade and gravel. The City will use surplus pea rock from the 2019 Chip Seal Project to backfill the drain tile. In addition, staff identified a low area that will require additional storm sewer pipe and a storm drain.
This resolution will increase the contract by $45,130.00 which will be paid out of the drainage fund and will extend the substantial completion date by two (2) working days for completion of the additional work.
