Body
Dear Sir:
On November 15, 2018, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 14-108-5F, Streambank Stabilization Projects for Addison Creek, Northlake and North Riverside, Illinois, to Industria Inc., in an amount not to exceed $1,546,000.00, plus a five (5) percent allowance for change orders in an amount of $77,300.00, for a total amount not to exceed $1,623,300.00. The scheduled contract completion date is January 9, 2023.
As of January 24, 2020, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $110,000.00 from the original amount awarded of $1,546,000.00. The current contract value is $1,656,000.00. The prior approved change order reflects a 7.12% increase to the original contract value.
Item 1: During in-stream work at the North Riverside project site, District field staff identified two backflow preventors on existing 6-inch and 8-inch storm sewer end sections that had failed and were resting in the creek bed. The District determined that two new backflow preventors and replacement storm sewer sections should be added to avoid potential backups during high flow storm events. On October 1, 2019, the contractor submitted a cost proposal (CO-03) for an extra in the amount of $4,365.69. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO03, that the Engineering Department would recommend its approval.
Item 2: In an effort to improve on the vegetated soil lift design based on previous performance observed, the District issued a request for proposal to Industria Inc. to increase the quantity of seeding and flood tolerant native plugs, and to install a geotextile material to retain backfilled soils. On October 16, 2019, the contractor submitted a cost proposal (CO-04) for an extra in the amount of $5,320.73. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO04, that the Engineering Department would recommend its approval.
Item 3: Two 30-inch diameter trees were identified in the contract drawings to be protected during the construction of improvements at the Northlake site. Upon inspection by District field staff, the trees were determined to be in poor health and posed a safety hazard to residents. The District issued a request for proposal to Industria, Inc. to remove both trees. On October 21, 2019 the contractor submitted a cost proposal (CO-05) for an extra in the amount of $4,070.00. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO05, that the Engineering Department would recommend its approval.
The above three change orders are in compliance with the Illinois Criminal Code since the changes are germane to the contract.
It is hereby recommended that the Board of Commissioners authorize the Director of Procurement and Materials Management to execute three change orders to increase Contract 14-108-5F in an amount of $13,756.42 (0.83% of the current contract value), from an amount of $1,656,000.00, to an amount not to exceed $1,669,756.42.
Funds are available in Account 501-50000-645720.
