FORMAT:Consent Agenda SYNOPSIS INCLUDING PRO & CON: Change Order No. 1 to RW Excavating Solutions in the amount of $24,270.00. During the pond excavation the material being dredged was determined to be unsuitable for disposal onsite as planned during the design process, and was recommend to be disposed of offsite. The original intent of the design was to mix the dredge spoils with the other excavated soils and place in the proposed berm at the end of the driving range. Duet to the amount of dredge spoils, silt material which does not support shaping due to a lack of cohesion between soil particles, there was not enough competent soil to mix the spoils with. After evaluation, it was decided that if the original design approach was followed, the berm would not be able to support golf course operation at project completion. Change Order No. 1 includes the cost for removing the dredge spoils, disposing the material offsite and for the cost of maintaining the truck route on/off the golf course. Representative from Bolten & Menk and City Staff have reviewed the quantities and find them to be accurate.

During the pond excavation at the Sugar Creek Municipal Golf Course, the material being dredged was determined to be unsuitable for disposal onsite as planned during the design process, and should be disposed of offsite. The original intent of the design was to mix the dredge spoils with the other excavated soils and placed in the proposed berm. Due to the amount of dredge spoils, silt material which does not support shaping due to a lack of cohesion between soil particles, there was not enough competent soil to mix the spoils with. After evaluation, it was decided that if the original design approach was followed, the berm would not be able to support golf course operations at project completion. It was determined that the dredge spoils would be disposed at an area at the public works facility north of the golf course using road legal dump trucks. Change Order #1 includes the cost for removing the dredge spoils, disposing the material offsite and for the cost of maintaining the truck route on/off the golf course. The original contract value of $135,805.00 will be increased by $24,270.00 to a new contract value of $160,075.00. Please see the Change Order 1 for a full summary of the additional items. It is anticipated that the total cost of the construction contract will be less than the revised contract amount as approved with this change order, approximately $15,000 due to underrunning of other contract line items. The exact amount of the deductions will be made at project closeout, and included in the final contract closeout change order. Bolton & Menk, Inc. recommends the approval of Change Order 1. Please let me know if you have any questions. Sincerely, Bolton & Menk, Inc.
