INDIAN RIVER COUNTY, FLORIDA MEMORANDUM B.E. CONSENT TO: Jason E. Brown, County Administrator THROUGH: Richard B. Szpyrka P.E., Public Works Director Nad FROM: Keith McCully, P.E., Stormwater Engineer SUBJECT: Approval of Change Order No. 2 to Work Order No. 2 and Approval of Final Payment of Work Order No. 2 with GK Environmental, Inc. for Osprey Acres Floway and Nature Preserve Landscaping Services. DATE: June 19, 2020 DESCRIPTION AND CONDITIONS Construction of Osprey Acres Floway and Nature Preserve (Osprey Acres) is complete and Work Order No. 2 with GK Environmental, Inc. for Shallow Marsh #2 landscaping services is complete. The purpose of this agenda item is to approve closeout of Work Order No. 2 and to approve Change Order No. 2 to clear up a final billing issue with GK Environmental, Inc. (GKE) regarding its work in Osprey Acres' Shallow Marsh #2 under the Work Order. To pay GKE's final invoice for Work Order No. 2, $651.25 must be added to the Work Order amount. The funding deficit resulted from unforeseen additional service work that GKE was required to perform during Osprey Acres construction. GKE was hired under Work Order No. 2 to perform landscaping and landscape maintenance services at Shallow Marsh #2, while the bulk of the project was still under construction by West Construction, Inc. (West). To meet grant construction timeframes, Osprey Acres was bid for construction before Shallow Marsh #2 landscaping design was complete. Staff subsequently completed the landscape design, and the planting and plant maintenance services were awarded to GKE, with the understanding with West that West would provide a firm calendar date as to when Shallow Marsh #2 would be ready to receive plants. This would allow GKE to schedule planting of certain landscape material in nursery containers so it would be the proper size when the site was ready to receive the plants. Unfortunately, West slipped significantly behind in its construction schedule after notifying GKE of the target planting date. Because of the delayed planting date, the potted plants grew too Targe for their containers, resulting in the growers having to split, regrow, and maintain hundreds of plants several times until the site was finally ready to receive them. Another unforeseen additional service item performed by GKE was caused by West's inability to properly regrade a Shallow Marsh #2 area that experienced serious erosion prior to GKE installing littoral plants in that location. After West made several unsuccessful attempts to properly regrade the area, staff verbally instructed GKE to perform the Work because West's inability to do the repair was preventing GKE from completing its planting. 48
